Welcome to the Release Candiate 3 Build 2715  


It is Very Important to read this entire file. Please read it. It contains lots of new info, on 
new features!  This file can also be viewed with NotePad and will install in the VO Root 
Directory ie \CAVO27\  This build will more than likely be the release build. Please test it
throughly.


Compiler:
=========
- Fixed several memory leaks
- Fixed a 'double memory free' problem that would trigger a 'Compiler memory Allocation Anomalies'
  dialog
- Fixed a problem with expressions such as xValue += 1 and xValue -= 1
- Fixed a problem with global arrays that were filled with a negative value, like in:
  GLOBAL aValues := {1,-1} AS ARRAY
  GLOBAL aValues := {1.0,-1.0} AS ARRAY
  Also added compiler warning for complex initializers such as:
  GLOBAL aValues := {-1.0 * 2.0} AS ARRAY [179]
- Fixed various other problems with negative constants [12483]
- Fixed a problem with operations such as: 
  Self:FloatIVar += -LocalVar and 
  Self:FloatIVar -= -LocalVar [12508]
- Fixed a problem with the optimizer and expression such as:
  x * 1, x / 1, x + 0, x - 0, x ^ 1, x ^ 0
- Fixed various problems with operations such as a := -b  and a := b + -c
- Fixed overflow errors and missing overflow errors for BYTES and WORDS
- Fixed a problem with compiling code where the return value of a PCALL was 
  passed as a parameter to another method/ function, such as in the next line:
  oRet := GetObjectByHandle(PCALL(gpfnSpltPaneAssocGet, SELF:Handle(), nPane - 1))


IDE:
====
- Touch all Entities did not refresh the Application Icon
- Fixed a problem where the debug status was not shown properly in some situations
- Added  "D <Off>" text in debug Column for entities where Debug is switched off at the
  module level.
- Fixed an alignment problem with Toolbar buttons
- Fixed transparency issues with some of the buttons in the various editors
- Pasting a module would not update the treeview properly. This has been fixed.
- Fixed some other refresh problems in the IDE.
- Switching projects will reread IDE settings and window positions from the Project File
- The 'Setup Project' menu option is disabled when 'Save settings in project file' is unchecked.


Debugger:
=========
- Fixed several memory leaks

Adam:
=====
- Fixed a problem that caused a GPF during reindexing
- Fixed a problem that would occur when recompiling the SDK libraries


SCC:
====
- Fixed several memory leaks
- Remove from SCC did not work. This has been fixed
- Fixed several other issues

Source code Editor:
===================
- Fixed a GPF when closing the window collapsed entities

GUI Classes

Fixtext.prg

Fixed bug in fixedtext:textvalue assign


Changes for 2715 
------------------------------
std_dlg.prg
Allow access/assign of default extension of StandardFileDialog

------------------------------
treeview.prg
corrected datatype of parameter of Treeview:__CreateDragImageList

------------------------------
edit.prg
Corrected spelling of SingleLineEdit:CreateFormattedString()

------------------------------
appwnd.prg
SELF:QueryOnClose() was inneffective for this class - now fixed

------------------------------
dialog.prg
New method DialogWindow:ExecModal()

Allows programmer greater control over Windows message handling in dialog windows.

Normally ExecModal() will cause program execution to pause when the window is shown and then continue once the window is closed. 

However the programmer can create a new class which inherits from DialogWindow implement his own method ExecModal(). As an example the programmer could use the following version which performs no action:
 
METHOD ExecModal() CLASS DialogWindow
    RETURN NIL
 
Now the program control comes back immediately after calling the
Show() method. This is very useful for cases where your
code wants to control the windows dispatcher loop with the function
ApplicationExec(EXECWHILEEVENT):
 
Method xyz() class xyz
    Local oPDlg as ProgressDialog // inherit from DialogWindow
 
    oPDlg := ProgressDialog{SELF, "Processing is going on!"}
    oPDlg:Count := oServer:Reccount
    oPDlg:Show()
 
    //ProgressDialog is modal, the user can do nothing during the processing other than what 
    // your code permits.
    //In this example you can abort the loop. 
 
    oServer:GoTop()
 
    do while oServer:Eof
        IF ! oPDlg:Step()  //FALSE if abort button is pressed - there ApplicationExec is called also.
            exit
        endif
        //do something
        oServer:Skip()
    enddo
 
    oPDlg:EndDialog()





2714 Start here

Adam
====
- When a new app is created, this app now gets a copy of the current default compiler 
  options from the project. This is done to avoid problems where an app would not compile 
  without errors after importing in another project with other default compiler options.

- Adam would die without graceful error messages when the maximum appsize was reached.
  It will now show an error dialog telling what has happened (and still die...)

--------------------------------------------------------------------------------
IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT
--------------------------------------------------------------------------------
- We changed the way RIDS in the Repository are created: 
  In the past a RID consisted of 12 bytes AID followed by 20 bytes Unique RID ID.
  We have changed this, because some of you were approaching the maximum app file 
  size (128 Mb).
  The new layout of the RIDS is now:
  8 bytes AID followed by 24 bytes Unique RID ID.
  This allows for larger App file sizes (2048 Mb) 
  As a consequence of this the maximum # of apps in a project has been reduced from 
  4096 to 256. We hope nobody has projects that large (the IDE would be crawling anyway)
  This also solved enhancement request [156]
- Exception errors are now also written to the file IDE-ERR.LOG. If you experience a GPF, 
  please attach this file when reporting the error.


Compiler:
=========
- Fixed problem where logical expressions (xx .AND. yy , aa .OR. bb ) were 
  NOT shortcutted in some situations [166] and [12507]


Import AEF and New App Wizard
=============================
- The show Readme dialog is not longer modal [12603]
- The import process does NOT show a dialog anymore when trying to extract external 
  files (such as PRGs, Resources etc), that are exactly ONE hour older or younger 
  than existing files on disk, to avoid unnessary warnings because of time differences 
  caused by Daylight Saving.
  The new behavior is that the existing file is NOT overwritten in these situations.


IDE
===
- Fixed a GPF when dragging a module from one app to another
- Listviews would be redrawn after changing Debug status of a Module/Entity. 
  This is now suppressed.
- Optimized some code to get even better performance when building the Listviews &
  Treeviews

Debugger
========
- Fixed the problem that modifying the value from a variable did not work in the 
  "View Locals" window [12451]
- When setting a breakpoint on a non-code line or a line that is part of a Multiple-
  line statement, the debugger now breaks on the last line before that line that has
  actual debugging info. 


Editor
======
- Size of function/method prototypes in the popup menu is now limited to avoid 
  the menu from overflowing the screen [12605]
- Removed blank entries from the "Go back" menu option [12598]


Automation Server code generator
================================
- Classnames that start with a number are now prefixed with 'VO' [12607]

Window Editor
=============
- Will now show confirmation when Ole Controls have been added/deleted to/from the 
  palette [12554]


Runtime
=======
- Fixed several issues with regard to the macro compiler:
  x Constructs like the following could fail when the GC was triggered:
    Evaluate ("oMyObject:X := oMyObject:Y") [91] & [131]
  x cMac := &("{|a|-1}") would fail [12570]
- Added symbol handling to the macro compiler. You can do this now:
  Evaluate("FieldGetSym(#LastName)")

_DBFCDX RDD
===========
- Fixed a problem with DbClearIndex [12595]
- Fixed a problem where Tags would be sorted alphabetically [12594]
- Speeded up OrderKeyCount in shared environments [85]

System Library:
===============
- The default error handler now adds a message to the error dialog when the Old
  runtime DLL (CAVORT20.DLL) is found in memory

   
Win 32 API
==========
- Fixed a prototype error for TabCtrl_AdjustRect [12614]

GUI Classes
===========
Added new module XP Theme Support

Window Class
============
- Moved theme related entities to Theme module
- Changes to support brush drawing
- fixes for W Moore issues of 07/12/03 - keyup & space to trigger button press

Control Class
=============
- fixes for W Moore issues of 07/12/03 - keyup & space to trigger button press


Window:Dispatch()
- Fixed the call to DrawThemeParentBackground

Brush Class
- Correct support for hatched and pattern brushes
- Allow change of brush type

TextControl:Brush
- Hatch/pattern brush support

textControl:BackGround
- treeview background fix

DataWindow:BackGround:
- improved background access/assign

__FormFrame:Brush
Fix problem with brush assignment to subdatawindow


Bitmap:init()
- DOC: second parameter is the load option see API LoadImage()
- added third and fourth parameters - width and height

Icon:init()
- Second parameter added - is the load option see API LoadImage(). Defaults to LR_DEFAULTCOLOR
- added third and fourth parameters - width and height



New Class: HyperLink (Thanks Sven Ebert)

- Inherits from FixedText. (No additional properties or methods)
- Mouse cursor changes to a hand when it passes over the control
- When the control is clicked on it will attempt to "open" the text of the control - See the WIn API ShellOpen for details on what "open" means. Essentially if the text is a URL then clicking the control will cause the default web browser to open and navigate to the URL. 
- If the text of the control contains the @ character then it will be automatically prefixed by "mailto:" (if it does not already exist) when the open is attempted
- Example:

oFont1 := Font{,8,"Microsoft Sans Serif"}
oFont1:Underline := TRUE

oHL1 := HyperLink{SELF,-1,point{190,25},dimension{0,0},"http://www.grafxsoft.com"}
oHL1:font := oFont1
oHL1:size := dimension{150,20}
oHL1:textcolor := color{COLORBLUE}
oHL1:font:underline := TRUE
oHL1:show()




VO 2713
=======


IDE
===
- Stops registering the .AEF and .MEF extension to avoid frustration for users using the 
  VOPP export explorer
- Fixed various refresh problems [12593]
- 'Save settings to project' on New Project dialog is now saved properly [12592]
- Fixed a GPF when opening the editor on a class entity in class view [12588]
- Pressing ^E will now open an EMPTY editor, even when an entity is selected
  in the listview


Compiler
========
- Fixed a GPF that could occur after switching projects in the IDE
- Fixed a memory leak that could occur after switching projects in the IDE
- Fixed GPFs reported by Wolfgang Riedman and Rod da Silva. 
- Now Recompiled with C7 !
- Fixed problem with initialization to 0.0 of Float IVars in classes
- Fixed various other errors


Source code Editor
==================
- Fixed a very difficult to locate memory leak !
- Some of the Edit menu options were disabled in this build. That has been fixed.
- Context menu will not replace context menu of the scrollbar anymore [12597]



Debugger
========
- Fixed a GPF in the debugger

Runtime DLL
===========
- Fixed a problem with Acopy [12582]
- _GetPrevInst() always returns a NULL_PTR. This function is not supported by
  Win32, but the Runtime function is kept for backward compatibility [12573]
- Researched problem that Beta tester has with the result from Integer(). Beta tester 
  was convinced that Integer() uses SINGle precision internall. The result:
  Integer uses DOUBLE precision internally. The algoritm used is:
   If x > 0
      return Floor(x)
   elseif x < 0
      return Ceil(x)
   else
     // x = 0
   return x
   I tested Floor with C++ and it has the same results [12571]
- Fixed a problem with StringAlloc: It used to stop copying when a NULL byte was
  encountered. it now copies everything, including the NULL bytes.[12586]



System Library
==============
- Fixed overflow errors in _UnformatC, _UnformatN and _UnformatL
- The Class WinDLLVersion has been moved from Windows 32 API Library [12581]


Windows 32 API Library
======================
- The Class WinDLLVersion has been moved to System Library[12581]


RDD CLasses
===========
- Fixed a problem with DbServer:Eval() with regard to scoping.


GUI Classes
===========

Note: some if the changes relate to "flicker" issues:

The developer must be aware that now a resize of a window not automatically
refreshes the complete window, only the new seen window parts are added to
the invalid window region and becomes repainted. If you need complete
refreshing of the window after resizing, simply add a SELF:Repaint() in the
Window:Resize() method.

Also there is a new Owner Alignment sample - shows automatic control
resizing and positioning when a window is resized.


------------------------------------------------
imagelst.prg
Changed ImageList:init(). 

Doc Update: 

Third parameter to imagelist:init() is a bitmap or icon object to add to the imagelist. 

Fourth parameter is Set of bit flags that specify the type of image list to create. This parameter can be a combination of the following values, but it can include only one of the ILC_COLOR values. 
ILC_COLOR
Use the default behavior if none of the other ILC_COLOR* flags is specified. Typically, the default is ILC_COLOR4, but for older display drivers, the default is ILC_COLORDDB.
ILC_COLOR4
Use a 4-bit (16-color) device-independent bitmap (DIB) section as the bitmap for the image list. 
ILC_COLOR8
Use an 8-bit DIB section. The colors used for the color table are the same colors as the halftone palette. 
ILC_COLOR16
Use a 16-bit (32/64k-color) DIB section.
ILC_COLOR24

Use a 24-bit DIB section.
ILC_COLOR32
Use a 32-bit DIB section.
ILC_COLORDDB
Use a device-dependent bitmap.
ILC_MASK
Use a mask. The image list contains two bitmaps, one of which is a monochrome bitmap used as a mask. If this value is not included, the image list contains only one bitmap.
ILC_MIRROR
Version 6.00. Microsoft Windows can be mirrored to display languages such as Hebrew or Arabic that read right-to-left. If the image list is created on a mirrored version of Windows, then the images in the lists are mirrored, that is, they are flipped so they display from right to left. Use this flag on a mirrored version of Windows to instruct the image list not to automatically mirror images. 
ILC_PERITEMMIRROR
Version 6.00. Specify this flag if ILC_MIRROR is used on an image list that contains a strip of images. ILC_MIRROR must be specified for this flag to have any effect. 

If you pass the fourth parameter you should include the ICL_MASK in the value.

Window:SetExStyle(dwSetStyle, lEnable). New method to set window extended styles

Window:DrawBackground(hdc, oWindow). New method. Called on WM_ERASEBKGND.

If you draw background for yourself return TRUE otherwise FALSE
The oWindow object is normally identical with SELF except SELF is a DataWindow. In this case oWindow can be the oSurface (__FormDialogWindow) object. In a DataWindow you should draw background ony if oWindow == oSurface, otherwise it is superfluous.

------------------------------------------------
fixtext.prg
FixedText:__SetColors()
Because the Fixedtext handles painting of background and textcolor for itself, avoid the call of      TextControl:__SetColors() in the new method FixedText:__SetColors() only if SELF:lUseDrawText is true

------------------------------------------------
txtcntrl.prg

Internet Classes
================
cEmail.prg, cftp.prg, chhtp.prg, cimap.prg, cmailabs.prg
cmessage.prg, cnews.prg, cnntp.prg, cpop.prg, csession.prg, 
csmtp.prg, csocket.prg, defines.prg, funcs.prg, rc.prg


The basis of these classes is the original VO SDK, substantially modified
by Uwe Holz. This library is a cut-down version to support FTP and Email
Classes only - most of the HTTP classes and IMAP classes work fine. Whilst
the original code worked perfectly out of the box, it nevertheless was
quite limited in its functionality. This is not a criticism as the sample
code and apps were provided merely as a start point to developing your
own classes.

The main improvements sought for our classes was to provide support for
multi-part and mixed emails. The original example classes cannot accommodate
this as sub-boundary conditions are required in addition to he main one.
Secondly, the original classes received, decoded and saved out the various
components of the email during the receiving phase. This is a problem if
there is a communications failure part way through. To compensate, our class
receives the entire email and stores it unencoded. The email can then be
decoded at will or retransmitted without modification. This also provides
for better virus and spam control.

The new classes also provide a mechanism to scan just the headers of the
emails without downloading the bodies. This can give rise to further spam
and virus prevention measures and also reduce download costs.

Next, the SMTP server was given an authentication mode to enable it to
offer separate login user name and password. SMTP servers will require
EHLO authentication instead of HELO.

Lastly, some of the decoding functions have been modified to work with strings
instead of files. These functions have been extended with the usual xxxEx()
nomenclature.



SDK
===
The SDK AEF files are now created during the Repo Build process, 
to make sure they have absolutely the same options that were used 
during the Repo build process






changes & fixes in 2712
-----------------------

Compiler 
========
- The ProcName/ProcLine switch now only sets ProcLine. ProcName is on by 
  default but can be switched on/off with the ~"PROCNAME+" or ~"PROCNAME-" 
  pragmas

- Fixed a memory problem that could cause a GPF in the compiler

- _sizeof() was returning a LONGINT. It now returns a DWORD (because size can 
  never be negative)

- The compiler now checks to see if a structure is a NULL_PTR before it
  accesses structure members.

- The compiler now checks to see if an object is a NULL_OBJECT before
  directly accessing ivars or calling methods on strong typed objects

  For example in a situation like this:
  
  CLASS MyObject
     EXPORT lValue as LONG
     
  FUNCTION Start
  local oObj as MyObject
   .
   .
  ? oObj:lValue

The compiler will now check to see if oObj <> NULL_OBJECT and will generate
a runtime error when it is indeed a NULL_OBJECT.
The error generated is EG_NULLVAR and can not be defaulted.



Runtime
=======
- The ClassChecking code generated by the compiler routine could generate a GPF 
  in the runtime if the object involved was not a valid VO Object

===
IDE
===

Settings
========
- The project Settings dialog has now a better place (in the File Menu). [12572]


Debugger
========
- Fixed a problem at program shutdown that could cause a GPF in the debugger [12548]


Editor:
=======
- If a method declaration line was split over more than one line
  the method-lookup combobox would not be displayed. This has been fixed.

New App Wizard
==============
- Fixed a problem with appwiz files pointing to the old \CAVO20 folder [12461]
- Fixed a problem with the appwiz dialog on Windows 98 systems [183]

Ole Automation Code generator & Ole Control code generator
==========================================================
- Code generation for the IUnknown and IDispatch methods is now suppressed 
  (QUeryInterface, Release, Invoke etc)
- Fixed a bug where Interfaces without Progid would get the progid
  from another Interface in the same typelibrary [EdR]
- Fixed a bug in the Code generation for OLE Controls that could occur
  when containing objects of type OleAutoObject were generated [12554] & [Oskar]
- Changed tab and new line generation in generated source code 
  to satisfy beta testers desires [12554]

Window Editor
=============
- Suppressed extra page feed when printing the window editors contents [12556]
- Fixed a problem with the resource generation for the ES_NUMBER style for
  edit controls [12557]
- Updated the credits screen 

Menu Editor
===========
- Fixed problem where toolbar local was generated after all buttons on a
  menu had been removed
- Removed the (unused) properties Gapsize and Seperator size in the Menu 
  Property Container
- Added Call to Self:PreInit() and Self:PostInit()
- Fixed a probem with the code generated for USe Bands [80]
- Fixed a problem when the ribbon name was changed from empty to <Auto> or back [81]
- Changed tab and new line generation in generated source code to satisfy beta 
  testers desires [Geoff & Patrick]

DbServer Editor
===============
- Fixed a problem when importing field names > 10 characters from a table that
  was opened using the ADSADT Driver [12471]
- fixed a problem in the [macros] section with the macro for the FieldSpec generation.

Jasmine support
===============
- Jasmine classes removed from system repository to the samples
- Jasmine editor not in CAVO27.CFG by default anymore

GUI Classes
===========
- Fix bug 185: Display of TabControl Tooltips Window.PRG
- Bug: in a number of places a single number (not one of the predefined) passed to Color{}, intention being it is the colorref. Changed those places: ListView:BackgroundColor, AppWindow:dispatch, RichEdit:textColor
- CheckBox access/assign image (related to earlier change for buttom images)
- Icon:Size access
- Fixed: FixedText wrapping 
- Fix Bug 98. ListviewItemDrag fixed. (wcstruct.prg, ddserver.prg)
- Fix "Bug" 12525. Owner draw support for controls/status bar: Control.prg, dispatch.prg, statsbar.prg, appwindow.prg

- Moved VOObject to System Library
- Window:ControlNotify performance improvements
- tool Custom draw support
  change to AddBand method so that it uses 3rd parameter iPos to determine where to insert the band
- Added Clipboard:FileCount - how many files dropped
- Added Clipboard:RetrieveFiles(lMustExist) retrieve array of filenames - if lMustExist is true the file must actually exist to appear in the array.
- Icon:init change to use LoadImage, avoiding the LoadIcon size restriction that icons conform to SM_CXICON/SM_CYICON system metric values.
- Windows:Dispatch Fix for animation control start/stop
- ImageList:imageCount - return number of images in list
- change to ImageList:AddMask - AddMask(oBitmap, oMaskColor) - allows mask color to be specified
- change to ImageList:init - allow imagelist without a mask if appropriate wColor specified
- New method Edit:CreateFormattedString() - this is called instead of direct assignment of __FormattedString, allowing overriding and use of something other than __FormattedString.
- FixedText control:
The changes that have been made to FixedText give the flexibility of using
the DrawText options. Included in this is the ability to set the FixedText
style to Transparent in the Window Editor - in VO 2.6 and before this was
not effective, in 2712 it is - without the need for the modified window
procedure.

If you really need the old style fixed text 2712 will have a instance
variable called lUseDrawText which defaults to TRUE but can be set to FALSE
for the old behaviour.

If XP themes are enabled and you want to stop the drawing of the theme background behind the fixed text then set the instance variable lDrawThemeBackground to FALSE

RDD Classes
===========
- Fixed a problem with SetOrder method [167] 
- Fixed a problem with OrderInfo method [12444]

Internet Classes
================
- Fix Bug 119: Change to cSession:Open to use proxy if already assigned. cSession.prg



System Library
==============
- Fixed a problem with SetOrder function [167] 
- Moved VOObject from GUI Classes to System Library
- Added oCargo as Object to the VOObject Class
- Fixed a problem in the __UnformatD function [12543] & [12555] 


Win32
=====
- Added support structure and defines for OsVersionInfoEx
- EnableMenuItem() changed to return a LONG
This changes the return value of Menu:DisableItem(), Menu:EnableItem() - they now return a LONG indicating the previous state of the item. If the menu item does not exist, the return value is -1.



changes & fixes in 2711
-----------------------

IDE General
==============
x Fixed a refresh problem in the Error browser
x When saving an entity in the editor the listview part of the RepoBrowser was redrawn a couple of time
  and the entity that was selected in the listview got deselected.
  The Listview now restores the selection to the entity with the same relative position in the list.
  If you are adding/deleting entities this may be a different entity, but otherwise the selection should 
  stay on the same entity in the listview.[12524]
x The linker dialog is now also visible when linking from the editors

Compiler
========
x The compiler would corrupt literal strings like "Test\%Hello" during the process of replacing
  macros such as %cavodir%. It would strip the first part of the string including the % character.
  This has been fixed.[138]
x Starting the compiler in the source code editor could lock the editor when a tokentip, parametertip
  of method listbox was visible.

Linker
======
x Fixed a bug that could GPF the linker when corrupted resource were being added to the EXE

Debugger
========
x Double clicking a binary Menu entity would open the menu definition in the editor[39]. This has
  been fixed. The new behaviour now is:
  - Double clicking a debuggable source entity opens it in the debugger
  - Double clicking other entities  (binary but also resources and external function declarations)
    will open the editor associated with the entity.

Sourcecode Editor
=================
x Create EXE button was enabled when editing a Library. has been fixed [12522]

Window Editor
=============
x Removing the FillUsing() for listboxes and Comboboxes would fail if the listbox was filled with a 
  literal array. This has been fixed [70]

Menu Editor:
===========
x Editing a menu entity could cause a GPF in the IDE. This has been fixed. [12537]


GUI Classes
===========
x Changed the __WCToolBarUpdate structure to get rid of 'member needs a kid' warning and asjusted
  the Toolbar code to work with the new structure [12475]
x Fix bug 185: Display of TabControl Tooltips Window.PRG
x Bug: in a number of places a single number (not one of the predefined) passed to Color{}, intention being it is the colorref. Changed those places: ListView:BackgroundColor, AppWindow:dispatch, RichEdit:textColor
x CheckBox access/assign image (related to earlier change for buttom images)
x Icon:Size access
x Fixed: FixedText wrapping 
x Fix Bug 98. ListviewItemDrag fixed. (wcstruct.prg, ddserver.prg)
x Fix "Bug" 12525. Owner draw support for controls/status bar: Control.prg, dispatch.prg, statsbar.prg, appwindow.prg
x Fix Bug 119: Change to cSession:Open to use proxy if already assigned. cSession.prg

RDD Classes
===========
x Fixed a problem with DbServer:Count() [12479] and [12535]
x DbServer:OrderBottomScope assign would return FALSE in stead of the scope value [84]
x DbServer:OrderTopScope assign would return FALSE in stead of the scope value [84]
x Assigning a NULL_STRING to a MemoField could cause a lock failer for two updates on the same
  record in Optimistic mode [130]

DBFNTX RDD
==========
x Order names were Case sensitive in 2.6. This has been restored to case insentitive just like in VO 
  2.5 and before[12477]
x Fixed a problem with seeking and scopes [84]:
  - Set TopScope to 'CA' and seek 'CA' now succeeds 
  - Set TopScope to 'CA' and seek 'CAM' now succeeds.
x Would return an OrderKeyCount == RecCount when no index was open  [12518] Now returns 0.

DBFCDX.RDD
==========
x Fixed a ansi-oem conversion problem that could occur with SetAnsi(TRUE) [2]
x Fixed a problem with SetRelation. Caused by same SetAnsi settings as before [180]
x Fixed a problem that immediately after creating an index the OrderInfo(DBOI_NAME) or OrderInfo(DBOI_FULLPATH) would
  return incorrect results.[59]
x Would return an OrderKeyCount == RecCount when no index was open  [12518] Now returns 0.


Runtime
=======
x Fixed a Round Error [15]
x Fixed a bug in Ntrim() for Scientific notation [12511], in combination with insufficient Digits for float
  values. [12511]
  With SetDigits(10 (The default) the values will now display as:
  9999999.1    9.999999e+06
  99999999.1   1.000000e+08
  999999999.1  1.000000e+09
  9999999999.1 1.000000e+10
x Fixed problem that would occur after you had set the memory size using the DynSize() function[63]:
  The Dynshrink function would then release memory until the number of pages that were speficied in 
  DynSize() was reached, even when these pages were in USE <grrrrrr>
  An example: 
  For example you set DynSize(5). Now your app uses 10 pages. If the DynShrink gets called (and it 
  is called internally in the runtime) it would shrink the memory to 5 pages, even though you were 
  already were using 10 pages!
x The Classname function now returns 'InvalidVoObject' for non-VO Objects (COM Interface wrappers)
x The AsString() function used to display the name of the last object when called on a Null_object. 
  This has been fixed. Now it does NOT display a name
x The asstring() method could GPF when called on a Non-Vo Object. It now displays 'InvalidVoObject'
x Added stricter object checking:
  The following code would GPF in previous builds and previous versions but will generate a decent 
  error message now:
  local o as Object
  o := Object(_CAST, 1)
  ? o:Test()
  o:SomeIVar := 1234
  ? o:SomeIvar
  Also corrupted objects are detected. The following code corrupt an object and the runtime would 
  generate a GPF. Now it detects that the object is corrupt and will not display its classname 
  and will generate a DATATYPE error when calling the Throw() message, because it detects
  that the object has been corrupted.

  local e as Error
  e := Error{}
  ? ClassName(e)
  MemSet(Ptr(_CAST, e), 0,8)
  ? CLassName(e)
  e:Throw()
x Added the IsVoObject() function to the runtime that checks if the given object is a valid VO Object
  It will check the object for the following:
  - Is it not a NULL_OBJECT
  - Can the header be read/written
  - Can the data be read/written
  - Can the Classpointer be read
  - Can the ClassInfo be read
  - Is the size of the object >= size defined in the ClassInfo

  It does NOT check :
  - if the object is located in the current dynamic memory pool
  - if all the dynamic properties of the object are valid

x Added the IsVoString() function that checks if a given string is a valid VO string. 
  It will check the string for the following:
  - Is it not a NULL_STRING
  - Can the header be read/written
  - Can the data be read/written


Changes in build 2710:
======================

IDE
===
- Adam will no longer disable the warning 51422 when initializing the repository
- Some of the Setup/Editor-Settings (for example Tabstops) were not saved properly
- Changed the caption of the Shellwindow to <ProjectName> - CA-Visual Objects
- Speeded up Repobrowser Listview redraw 
- Fixed various problems when renaming the current project. 
- The project properties dialog now has an option to specify if you want to "store settings
  in project file". When checked the IDE will read the system settings from the VOPRJ file.
  When unchecked it will only read settings from the CAVO27.CFG file.
- Some subsystems were bypassing the project file to read their settings. This has been 
  changed.
- Added TemplateDirectory to System Options dialog. This is written to the entry Templatepath in the [Directories] section of Cavo27.CFG and the VOPRJ files.
The DbServer Editor, FieldSpec Editor and Window Editor now use this directory to locate the template files. 

There is no Project Settings dialogs right now (will probably come in next build) but this feature will allow you to have project specific templates

DbServer Editor:
================
- Reads template from Template Directory
- The code generation for Server:FieldDesc and Server:IndexList was partially hardcoded.
  That is now also template driven.
  We have added a [MACROS] section to CAVODED.TPL that has currently 3 entries:
  - FieldDesc
  - Index
  - Order
  Each entry has a template for that particular piece of code.

  Something that you may not be aware of in relation to the DbServer Editor:

  You can add as many sections to CAVODED.TPL as you like. Each section will 
  generate its own entity. You can use all the macro strings that are used
  everywhere else in the CAVODED.TPL. 


FieldSpec Editor:
================
- Reads template from Template Directory


Window Editor:
================
- Reads templates from Template Directory
- FieldSpec properties were removed for Dialog Windows. That has been changed. 
  It is now also possible to assign fieldspecs for Controls on dialog windows


Compiler:
=========
- Fixed a bug with Peephole Optimization involving byte sized or word sized members
- Fixed a bug with determining the size of structure members
- Fixed "GetExpDescriptor failed" message for Register variables (_BP, _CS, _DS, _ES, _SS) in debug version   of the compiler
- The behavior for strings with embedded ampersands has changed. See example below
  Function Start
  MEMVAR WORLD
  WORLD := "Robert"
  ? "Hello &World"	
  // 2.6 will display Hello Robert
  // 2.7 will display Hello &World
  // To get the 'old' behavior you need to call the StrEvaluate() function.
  ? StrEvaluate("Hello &World")
  // All versions of VO display "Hello Robert"
  wait
- A bug with compiling textblocks has been fixed.
- When initializing the repository Adam would disable the check for warning W51422 
  (converting numericals x <-> y). This has been disabled.

CAVOLBOX.DLL
============
- Fixed a problem that could cause a GPF in the debugger

Runtime
=======
- Fixed a problem with the Crypt() function
- Fixed problem with conditional indexes where the Index conditions had an embedded
  ampersand.
- MemCopyString would not pad the memory block with spaces, but NULLS when the source
  string was shorter than the memory region. This has been fixed
- Asort() would not accept objects with an eval method. This has been fixed
- ASort() would only work correctly with strings of unequal length if SetExact() was TRUE.
  Now it turns SetExact(TRUE) on internally when needed.
- Str(123.45,4) would return "****" in VO 2.6. Restored old (2.5) behavior which returns "123."
- Fixed an out-of memory error that could occur during repeated floating point calculations in a loop with no other operations that triggered dynamic memory allocation.
- "Dynamic Memory Low" erorr messages would try to allocate dynamic memory for the errorbox   This could cause recursion in the Error Handler, resulting in a GPF in kernel32.DLL. 


- Fixed a stack corruption error in OleFrame::OleFrame()


Ole Runtime:
============

- Fixed a Dynamic Memory corruption problem in the Ole Runtime where
the GC was called in the event handling code.

- Fixed a stack corruption error in OleFrame::OleFrame()


_DBFCDX
=======
- Fixed a problem that was introduced in the first release of 2709

All VO Code 
===================
- Changes to remove 51422 warnings

System Library
==============
- Fixed a problem with the missing Default Error Handler that was introduced in 2709.
- Fixed a problem with the OrdCondSet() function 
- Fixed a problem in SetInternational that could cause the default value for SetDecimal()  to be incorrect
- Fixed various 51422 warnings


System Classes
==============
- strong typed some internal methods in DataServer and FieldSpec


RDD Classes
===========
- Fixed a problem with DbServer:GetLookupTable()
- DbServer:Commit() could fail for Float values because of differences in non-significant
  decimals. The relevant code in DbServer:__RLockVerify() has been changed to only check for the significant decimal positions
- DbServer:OrderInfo() did not use the 4th parameter. This has been fixed.
- DbServer:Rlock() would fail when no recordnumber was passed to it. This has been fixed.
- DbServer:Total() would produce an empty result file when a For or While condition was set without a Scope.

SQL Classes
===========
- Fixed a problem with SqlSelect:Delete() where the last column is a Long Column
- Fixed a problem with SqlSelect:AppendRow() where the last column is a Long Column
- Fixed a problem with SqlConnection:Connect() where the DataSourcename or the UserId or the Password is exactly ONE character !
- Fixed a problem with SqlSelect:FieldPut() for Decimal & Numeric Columns


GUI Classes
===========


Button
------
Under XP Visual Styles the image on a button needs to be provided in an imagelist. The button class will now automatically convert an image into an imagelist under XP visual styles.

Button ACCESS/ASSIGN image - changed to internally use an imagelist under XP visual styles
Button ACCESS/ASSIGN imagelist - used when run under XP visual styles

New class: ButtonImageList, inherits from ImageList.

ButtonImageList:Init (oImage) 
	oImage == Icon/Bitmap object
	only one image in ButtonImageList
ButtonImageList:image
	return the image from the imagelist


----------------------------------------
FixedText
New method: SetDrawStyle(dwStyle,lEnable) see API DrawText() for dwStyle values

----------------------------------------
Bug 103: Doc Change

If you don't want to define your own resource you need to pass "IDD_DEFDLG" for a child dialog or "IDD_DEFDLG2" for a popup dialog.

e.g. 

o := DialogWindow{oS,"IDD_DEFDLG",TRUE}

or 

o := DialogWindow{oS,"IDD_DEFDLG2",TRUE}

It is likely that you will also want to set the size and the origin.

----------------------------------------
Fix to __SplitView:SetPaneClient() 
only call set style if parameter is a window

----------------------------------------
Listbox/Combobox

Text typed into a combobox edit did not update textvalue or value properties. Fixed.
Bug 12457: Also corrected problem from 2708 where querying textvalue after window was destroyed returned a NULL_STRING.


Corrected behaviour when text typed into combox box to match the docs: "When text is directly entered, ComboBox:CurrentItemNo is set to 0 and the new text is stored in ComboBox:TextValue and ComboBox:Value."

Allow assignment of NIL to listbox value - reset Textvalue to NULL_STRING, CurrentItemNo to 0 and CurrentItem to NULL_STRING.

Related bug 112 and response:
There appears to be a bug in the ComboBox Value property. It will never return to NIL once it has had a value. For example if you have a dropdownlist combobox on a form and select an item from it Value changes to reflect that choice. However, if you then set the CurrentItemNo to 0 using code the Value property still reads the same as before, rather than reverting to NIL.


It appears that the Clear, FillUsing and maybe other methods do not
refresh the Value property either.


When CurrentItemNo is zero it is still possible to have a combobox textvalue and value. c.f. Combobox Class in the help: "When text is directly entered, ComboBox:CurrentItemNo is set to 0 and the new text is stored in ComboBox:TextValue and ComboBox:Value."

However it is now possible to assign a value of NIL to listbox. This resets Textvalue to NULL_STRING, CurrentItemNo to 0 and CurrentItem to NULL_STRING.

Clear and FillUsing now reset value to NIL.

Note: ACCESS TextVaue CLASS CheckBox removed, now handled by super.
----------------------------------------


30 Sep 2003

----------------------------------------
Fix Bug 12478: CAVOWED.INF. Inclusion of Day State in Month Calendar styles.

----------------------------------------
Fix Bug 12476: Diagnosis of problem (mousemove behaviour) not 100% but bug found in BoundingBox:PointInside()

----------------------------------------
Fix: HelpDisplay:Show() Parameter of HelpContents did not show the contents page correctly. Fixed for HLP and CHM.

There is a new value for Show() first parameters: HelpSearch (applicable to HTMLHelp only) executes HH_DISPLAY_SEARCH, i.e. selects the Search tab in the help navigation pane.

There is a new second parameter to Show() (applicable to HTMLHelp only). symLookupType controls the lookup type:  
HH_KEYWORD_LOOKUP or HH_ALINK_LOOKUP. Keyword lookup is the default. ALink is used to call up Associative links in the helpfile. Associative Links are not displayed in the index, keywords are.

New instance var: DefaultPageOnContents. (applicable to HTMLHelp only) LOGIC. Determines whether the default page should be shown when HelpContents is requested. Defaults to TRUE. If FALSE, HelpContents will display the Contents tab but leave the current topic displayed.

----------------------------------------

DOC Change:

HelpDisplay:Show()

HelpIndex
-----------
The VO help says this:

HelpIndex: Displays the Contents topic as defined in the application help file

which is incorrect. It should say it brings up the Index page.

HelpOnHelp
-----------
This only exists for old HLP - it calls up WinHelp.HLP. There is no equivalent for CHM.


----------------------------------------

New: 
Clipboard:InsertRTF(cRTF) insert RTF string into the clipboard
ClipBoard:RetrieveRTF(dwLen) get RTF string from the clipboard

Help Files
-------------
New help file (Work in Progress) constructed with Help & Manual

Known Issues already fixed in 2711 (GUI Classes)

-Fixed Text does not wrap
-Use of an icon on a button will give an error
-an image on a checkbox does not show




Changes in 2709
===============



SDK
---
x Renamed some files to avoid file name conflicts when all the PRGs are
  copied to the same folder

x Removed some unused defines and string table resources from System Classes

x Added define WM_VOAPP (WM_APP + 0x1000) to Windows API
  This define can be used by VO users to avoid conflicts with windows messages
  used in the VO runtime classes

x There are LOTS of changes in the runtime code. They are listed below.


New DLL names
=============
x VO27RUN.DLL replaces CAVORT20.DLL
x VO27NAT.DLL replaces CAVONT20.DLL
x VO27ORUN.DLL replaces CAVOOLE.DLL

Note:
------
This may also influence C Dlls/RDDs that you have created before. We will upload a
new VO27RUN.LIB and VO27NAT.LIB to the Beta FTP site, so you can relink your C DLLs.
Please make sure you use these. Please don't use the old CAVORT20.LIB and CAVONT20.LIB anymore !

Do NOT cheat and copy CAVORT20.DLL in the directory and  keep using this one. You will
have two copies of the Workarea system and two copies of the memory manager running at the
same time, and we are pretty sure you will get all kind of unexpected results !

Changes in the runtime
======================
x the RDD_VERSION has been incremented to 2700 for this build.This will/should break
  olrder RDDs

x While expression for VoDbLocate() was not registerkid properly

x Default Memory settings are no longer read from registry. You will have
  to use the Set..() functions that we have listed below. We are still
  open for suggestions if you think that one of the defaults is too large or too small.

x Default RDD, HPLocking, NewIndexOffSet are not read from registry anymore. You need 
  to use the existing built-in functions (RddSetDefault(), IndexHPLock() and 
  NewIndexLock()) to enable them in your application

x STOD() function now accepts string and not a PSZ

x FERASE() function now accepts string and not a PSZ

RDDs
====

- DBFCDX, _DBFCDX, DBFMEMO, DBFBLOB are now all recompiled in C71.

- All RDDs now use the new Vo27RUN.DLL and VO27NAT.DLL


SDK
===

- The SDK code now links to the new VO27RUN.DLL, VO27ORUN.DLL and VO27NAT.DLL


GUI Classes
===========
- During the migration of OLE code from OLE to GUI some of the code got lost.
  This has been corrected in 2709.



Adam
====

x Added support for %templatedir% and %projectdir% system variables

x Fixed a problem with trhe Class Dependancy file for the System Library during System Building

x Caches system variables (such as %cavodir% and %aefdir%) during the build process to increase
  compilation speed


IDE
===

x The compiler runs now in the foreground in stead of a background process. This should increase
  the speed of the compiler. The progress info from the compiler is now also shown on a progress 
  dialog. Please let us know what you think of this.

x Fixed the error message on the Project Selection dialog after reindexing a project with no project 
  open.

x fixed an icon problem with the Window Editor


Known problems
==============
x There may be incorrect compiler warnings when using structures or typed pointers when
  you have type inferencing enabled

METHOD ShowEditBalloonTip(cTitle,cText,dwIcon), 
METHOD RemoveEditBalloonTip()

A balloon tip can be displayed pointing to an edit control. Edit balloon tips are only available under Windows XP or later.

The tip always points to the current cursor position within the control, and is dismissed by either clicking on it, by moving focus to a control other than the control the tip is assigned to, or by typing into the text box. Showing the tip automatically sets focus to the control at the last cursor position. A form can not show more than one tip at a time, and if the tip is repeatedly shown, the previous tip is destroyed first. Tips never get focus, and there is no message sent when the tip is dismissed. If the tip is displayed up to the system timeout value for tool tips, it automatically disappears leaving focus on the control. 

cTitle 
Title displayed in the tip

cText
Text displayed in the tip

dwIcon 
TTI_ERROR Use the error icon.
TTI_INFO Use the information icon.
TTI_NONE Use no icon.

Changed/Fixed in 2708:
======================

General:

- VOPRJ files are now associated with VO in the windows explorer.
  Opening a VOPRJ file will open the project in VO IDE, unless it
  is already opened in another IDE.

- The Project Listview has a new menu option 'Create Shortcut on Desktop'.
  This will create a shortcut to the selected VO project on the
  Windows Desktop (The User Desktop).


Because VO now creates new registry entries for the file associations,
exiting associations for the AEF and MEF files are overwritten. 

If you have associated AEF/MEF files with Pauls VO Export Explorer, 
You will have to manually re associate your AEF, and MEF.


Compiler:
=========
- Sometimes the message "Out of memory in ProcessGlobalEntity" was shown. This has been fixed.

Preprocessor:
============
- A bug is fixed that could cause a GPF in the preprocessor

Repository:
===========
- When an AEF has an external file that needs to be extracted to a non-existing directory
  a question will be asked if the directory should be created.
  When no is answered, or the creation of the directory fails, the file is extracted to the
  current directory

IDE:
=====
- The New project dialog is now larger and centered on the screen
- The Select directory buttons in the IDE now use the new style BrowseForFolder dialogs and 
  also allow you to create a directory
- File/Import dialogs are now resizable
- File/Export dialogs are now resizable
- The File/Export All progress dialog show project name of project being processed.
- Ctrl-E would not open new entity in the editor anymore. Fixed
- VOPRJ files are now associated with VO in the windows explorer. Opening a VOPRJ file will open the
  project in VO IDE, unless it is already opened in another IDE.
- The Project Listview has a new menu option 'Create Shortcut on Desktop'. This will create
  a shortcut to the selected VO project on the Windows Desktop (The User Desktop). 



Window Editor:
==============
- Double click on a tab page would not open the form. This has been fixed
- An GPF in cavoatom could occur when saving a new form. This has been fixed
- A couple situations with uninitialized strings were found and fixed

Linker:
=======
- Linux support has been disabled
- The binary file headers that are attached to every EXE and DLL are now without version
  number and the names of the former developers have been removed

Runtime:
========
- A bug in _DebOut32 (that would show double lines when run as an exe) has now been solved. 
- VODBOrdSetFocus could fail if the GC was activated from the RDD. This is now fixed.
- VODBOrderInfo could fail if the GC was activated from the RDD. This is now fixed.
- VODBSetOrderBlock could fail if the GC was activated from the RDD. This is now fixed.

GUI Classes
===========
- A Vo ChildAppWindow running in a foreign environment that received a window handle as parent (such as
  VO subsystems in the IDE or a VO DataWindow activeX running in another app) would generate
  a runtime error in the init method. This has been solved.


GUI Classes & OLE
=================
- There were several Ole related window methods (for AppWindow, DataWindow & ShellWindow) that were
  stored in the OLE Library. These methods have now all been moved to the GUI classes
  In those situations where they actually refer to classes in OLE (such as OleObject) or to functions
  in CavoOle.DLL checks have been built in to test for the existance of the classes or the existance of
  CavoOle.DLL.

OLE
===

- OleAutoObject:Init() now also accepts another OleAutoObject as the first parameter.
  This means that in situations where you only know the type of an object at runtime you 
  can still use the generated code.

  For example the Outlook Items collection may return different types of items, depending of the level
  in the folder hierarchy you are. The generated code looks like this:

  // To use a pre-defined class here,
  // change OLEAutoObject to desired class name
  uResult := if(uRetValue:pInterface!=NULL_PTR, OLEAutoObject{uRetValue}, NULL_OBJECT)


  Unfortunately you can't change this since you don't know the type at compile time.
  The new feature allows you to do the following:

  local oContact as OL_ContactItem
  local oItem 	 as OleAutoobject
  .
  .
  oItem    := oItems:Item(1) 
  oContact := OL_ContactItem{oItem}
  .

  Of course the reference count on the item object is incremented because there are now two VO objects
  pointing to the same ContactItem object !

- There was an error in the OleAutoObject class that caused all dates to be returned as NIL. This has been
  fixed.

- OleObject:CreateFromInsertDialog would fail with the VO 2.7 code. This has been fixed.

Ole Server
==========
- Type library generation was broken in 2707
- Dispinterfaces now have a leading underscore in stead of a trailing underscore to follow the Ms Standards
- Exported Floats were mapped to singles (Real4). They now export as double (Real8)

- Reindex from Project Dialog will yeild the message "Can not get the applications" This will be 
  addressed in the next build 2709 







Changes in 2707

Compiler:
----------
- Fixed bug that would show message 'Too many words in UDC' after changing projects

Adam:
-----
- When a UDC or CH file is written to a different location during import, the application properties
  are adjusted to reflect this.
- Changed .APP extension to .VOA to avoid problems with System Restore on Windows XP and Windows ME.
- Deleting a project will now also try to delete the project folder if it is empty.


Menu Editor:
------------
- Accelerator for the Numeric Delete key (VK_DELETE) is not correctly generated
- Fixed problem that the new Link button was not working. 

IDE:
----
- Adding or Opening projects now also selects the project
- Some cosmetic changes with regards to the Listviews in the browsers.
- The code that shows Readme textblocks after importing could hang the IDE when running
  in release mode. 
- Treeview Root in explorer window shows build number (during Beta)

Ole Automation code generation
------------------------------
- Ole Code generation for OleAutoObjects and OleControls fixed
- Code generator now uses the new 'Prefix' and 'remove underscore' features. This also
  helps to avoid name conflicts with built-in classes.
- Ole Code generator now also includes the necessary libraries in the app 
  (OLE for OleAutoObjects, Ole, GUI, System Classes for OleControls).

Debugger:
---------
- Tooltips in the debugger are now working again !!!!
- Fixed a bug with Debug/Workareas

Editor
------
- F12 key (Save) now works as before
- Fixed problem when deleting rows with bookmarks on them
- Fixed problem that the new Link button was not working. 
- Fixed problem that "Goto Linenumber" on the Goto dialog (^G) was not working properly.

Runtime:
--------
- OS Function now has an extra parameter. Without the parameter the functions returns 
  "Windows 2000 ....." for W2K, WXP and Windows Server 2003.
  With the parameter (the type is unimportant) it returns the correct OS name, such as
  "Windows XP" or ""Windows 2003 Server"

- The Instring() function and $ operator would sometimes return incorrect results. This has been
  fixed.

- The MakeLong function (Windows 32 API, Module Windef) now returns a Long (as the name suggests) in
  stead of a DWORD

Image Editor:
-------------
- starts properly
- fixed 2 memory leaks


Known Issues:
-------------
- There is a small memory leak when switching between projects because the compiler does NOT free some
  of its memory properly
- Reindex from Project Dialog will yeild the message "Can not get the applications" This will be 
  addressed in the next build 2708 







Changes in 2706:

Explorer windows
================
x Some menu commands would not work from the Explorer. This has been fixed.

x When no window positions were saved the IDE would open with a treeview only

x Changed the Clipboard Formats, to enable Copy/Paste between different concurrent
  IDEs

x Added Autosize for All columns of the listview. 

  PS: We will need to see if this works on all Win32 platforms and it this does not 
  slow down things too much.


Menu Editor
=====================
x Added Linker button To the toolbar
x Added 'Inherit From' property for the toolbar in the menu properties list and 
  changed the Sourcecode generation to use this
x Enabled Promoting/Demoting for menu separators 
x Fixed memory leak in CavoLBox.DLL


Source code editor
==================
x Added Linker button To the toolbar

x Changed right mouse menu behavior in the Editor:
   Actually there were a couple of different right mouse menu options, depending
   on the context
   1. Goto Menu
      a when on class name, it would show Class declaration and Init method
      b when on an access/assign/method it would jump directly to the access/method
   2. Expand Prototype
   3. None
   All of them now show Cut/Copy/Paste first, followed by a seperator and the optional
   list of Goto items.

   Also changed the editor to NOT drop the highligh for a selection when the right 
   mouse menu is selected.

   In case nothing is selected VO will default to cut/copy the current line

   Also Change Windows popup menu key to show right mouse menu in the editor
   And Finally the F11 key has the same behavior as the Windows Popup Menu key.

x  Something that needs to be documented:
   When you issue a Goto.. from the right mouse menu, VO remembers the current 
   entity. By clicking Shift-F11 you can skip back to that entity.
   You can also remember the current entity by pressing the Ctrl-F11 key

x  Ctrl-G will now show the Goto-Routines dialog. Added a Goto Line number button 
   on this dialog

x  Added a "Edit All" button on the Find-Advanced dialog


Note There is still a small memory leak in the editor. 



Debugger
========
x Fixed/Checked issues detected during Beta. Especially the GPF when running in the IDE.
  This was caused by the IDE not checking the Thread Id of the process to run.

x NULL_OBJECTS and NULL_ARRAYS now displayed in the Debugger in stead of the 
  {|00000|0x00000000} notation. Also NULL_PTR now displayed in stead of the 0x00000000 notation

x fixed a problem in the View/Locals window where a usual that changed type was not properly
  displayed (It would display another local twice !)



Project Selection Dialog
========================
x The Reindex button will now reindex the right project !
  It also closes the current project before the reindex and reopens it afterwards

x The Reindex and Delete buttons will check to see if a project is in use before 
  continuing

x Display the Username and Workstation name that have a project locked in the Listview

Repository
==========
x Recompiled without overflow checking

Runtime
==========
x Fixed a bug in the Runtime where Symbol2String() would GPF for a NULL_SYMBOL

x Fixed a bug in the Nation module that prevented CAVONT20 to load


Repobuilder
===========
x Checks if it is not running twice


Fixes in 2705:
==============

- Bug in the runtime caused the Pizza sample to fail
- Save/Restore desktop works again
- Added Icons for Project Selection Dialog


=====================

New features: 2704
=============
- New project Selection Dialog. ALso gives access to:
  x Delete/Remove Project from Catalog
  x Create/Add Project to catalog
  x Reindex Project

- IDE opens with project selection Dialog

- Changed Adam to start without open Project. In this new situation you MUST select a 
  project using PrjSelect() before you can actually use Adam

- Initializing the Compiler will only work when a project is loaded. (It caches commonly used
  entity IDs and Atoms). Therefore the call to CompInit has now been moved to the _PrjOpen() 
  function

- For the same readon CompExit() has been moved to _PrjClose()

- Added function PrjOpen(LPSTR ProjectFileName) to Adam
- Added function PrjClose() to Adam

- Selecting a new project in the RepoBrowser now will result in a refresh of other open
  RepoBrowser windows as well.

- Most of the subsystems have the memcpy, memmove, memset and memcmp functions now 
  redirected to vomemcpy, vomemmove, vomemset and vomemcmp (in CavoStr.Dll). These 
  functions perform a an additional memory check operation to check for the memory 
  status. This is done in an attempt to find all locations where memory 
  corruption is caused. This has severe performance consequences, but it helps us 
  find a couple  of spots where corruption occurred. The behavior can be switched ON
  by including the define VOMEMCHECK for the project.
  At this moment the behavior is activated for:
  CAVO27.EXE, CAVOACT.DLL, CAVOEDIT.DLL, CAVODED.DLL, CAVOERR.DLL, CAVOFED.DLL, 
  CAVOIED.DLL, CAVOJED.DLL, CAVOLBOX.DLL, CAVOMED.DLL, CAVOSED.DLL, CAVOSSYS.DLL, 
  CAVOWED.DLL

- Changed all IDE subsystems to NOT use FindWindow anymore to locate their 
  FrameWindow,  but Look Up into the Window chain to find it.

- Added EIDMGR_NOTIFY, PROJECT_CHANGED event to the IDE. Gets send after new project has
  been selected. Is used by explorer windows to refresh themselves. 

- Increased Max # of Search libs for one app from 32 to 48

- Increased Max Length of Application/Module names from 31 to 63

- Increased Max Length of project names from 31 to 63

- Debug version of Adam shows progress between Compilation Cycles during AppMake
  Appmake compiles in the following order:
  In   Compilation Cycle 0: defines, Classes, structures, globals
  In   Compilation Cycle 1: anything except methods, accesses, assigns
  From Compilation Cycle 2: anything, that is left

- Adam will automatically create a backup of Cavo27.CFG (Called Cavo27.VO) if it can't
  find this file. When Cavo27.CFG is missing it will try to copy the contents of 
  Cavo27.VO or display a fatal error message if that file is missing as well.

- If you add the entry BuildIniFile=1 to the [Adam Options] section of the Cavo27.CFG it
  will add all entries to the CFG file that the program tries to read and can't find.




Fixes:
======

- Fixed memory leak in the Repobrowser that would occur when an Application Filter was set

- Fixed memory leak in the Editor

- Fixed memory corruption caused by the Compiler

- Fixed memory corruption in the Debugger

- Fixed Overflow error in the Linker

- Removed some unused Menu resources from the IDE

- Removed some duplicate strings from string table in the IDE

- Removed some duplicate code for MessageBoxes (ie: loading strings from stringtable) in the 
  IDE by calling the VoMessageBox() function in stead

- Moved calls to EIDMgrExit() and EIDMgrInit() to IDEPrjSelect, to make sure they are in balance

- Debugger seems to work now, after the fixes mentioned above

- Reindex program now works, and displays the correct version number 

- Incorporated the GUI changes from Paul.


Known Problems:
===============
  
- The Tooltips in the debugger are not working in this release. This causes memory corruption
- Restoring the Desktop does not totally work as expected. Fixed in 2705

For a next build:
=================
- Associate .VoPrj files with VO and open them on double click
- Create Shortcuts to the Project files in the \Cavoxx\Projects folder and/or the desktop
- Lock icons for locked projects in the Project Selection Dialog.// Added in 2705


Notes for the DOC/Help-team:
============================
- we need to add help for the Project Selection Dialog (and a HELPID for the IDE)
- We need to add help for the Project Open Dialog (and a HELPID for the IDE)
- Document new SDK functions 

        PrjOpen(LPSTR ProjectFileName) 
        PrjClose() 



Enhancements in this build.
 

IDE.
Like Visual Studio and most other Dev. products, VO now will run multiple copies of itself! 
The IDE has also been changed not to open ALL projects upon startup.(It's default behavior with 
2.0,2.5, and 2.6) With version 2.703 VO will open the default project. (This will change in 
future versions.)You may now open multiple copies of VO with a different project in each.
You may *NOT* open the default project,or any other project twice. To run more than one copy 
of VO for now.

o  Open VO with the default repo.(This is the default behavior for now)
o  Create a second project
o  Switch to Project 2 by highlighting vo's top level in the repo browser.
o  In the right panel of the repo browser you will find a list of your current projects. 
o  Highlight the project that you want to open. (Project 2) 
o  Right Click you mouse and select the open project. You can also use double click to open.
o  You are now running the first copy of VO with project 2 open.

Start a new copy of VO, this will open with the default project. 
You now have second instance of VO running!

Once again, you can not open two copies of the default repo, or any other project. You will 
receive an error saying that the project is in use by (username) We are still working on making 
this error happen for the default project, but if you try to open the default project twice 
you will get some ugly error. (This will obviously change in future builds)  

Take a look at File--setup options under the explorer tab. Something that most VO programmers 
have been asking for...Please report any problems with this, as we have had a few reports, but 
can not reproduce them. (If I only had a nickel for every time I've said, 
"it works on my machine")

VO2704 has more debug information in it. We have had a number of issues with un-initialized 
string values. If you see any error messages, please report them with the steps to reproduce 
them.

Report Bugs to Bugshunter@cavo.com
All bugs reported should have small AEF attached to.(If possible,if not a small set of 
steps to reproduce the bug will be sufficient along with a bitmap of the error 

If your receiving this Beta, it's probably because you've reported a bug in the past.
Please test your bug, and let us know 1. It is still a problem, or 2 the issue has been 
resolved.
