MFC Fixes

The following MFC issue has been fixed:

Alpha Fix: The FindTextA functionality cannot use some common dialogs, such as CFindReplaceDialog.

Debugger Fixes

The following Debugger issue has been fixed:

Alpha Fix: IDE remote debugging causes a dialog to appear with the error "Cannot initialize the debugging subsystem."

General Debugger note:

Whenever you have a conditional loop that is given an integer as its condition, as in the case of while(1), the Alpha compiler will optimize the loop out of the executable image.

The following code illustrates how to work around this issue.

Code example of issue:

SendMessageFunc();
int myi9=0;
while(1); // loop line.
myi9=1;
return 0; // return from WinMain().

Code example of workaround:

SendMessageFunc();
int myi9=0;
bool btrue=true; // or bool btrue=1;
while(btrue); // loop line.
myi9=1;
return 0; // return from WinMain().
//By replacing the while(1) with a while(variable=true), the problem goes away.// 

SP3 will update MSVCRT40.DLL  from version 4.10.6038 to version 4.2000.0.6171. Version 4.2000.0.6171 is a forwarder .DLL. Calls are forwarded to MSVCRT.DLL.

MSVCRT40.DLL version 4.1.6038 contains a bug detailed in the ReadMe.htm document in the x86 release of Service Pack 3.

Refer to Knowledgebase article Q214661: Daylight Savings Time Bug in C Runtime Library for more information. MSVCRT.DLL will provide correct functionality.

Note   Windows NT3.51 does not include MSVCRT.DLL. Therefore, if you need to redistribute MSVCRT40.DLL for deployment on NT3.51, it should be redistributed with MSVCRT.DLL.

Note   When using the Package and Deployment Wizard to genarate a package against an application which uses msvcrt40.dll, you need to manually add msvcrt.dll to the package.

Sample Case:
1. Launch VB with standard EXE
2. Add reference to DAO 3.51 Object Library (dao350.dll)
3. Compile this project and generate a package with the Package and Deployment Wizard

Result:
msvcrt40.dll (the forwarder dll) is included in the package but msvcrt.dll is not. To ensure your setup kit will install msvcrt.dll, use the PDWizard to manually add a reference to msvcrt.dll as shown below:

1.  Launch PDWizard and choose a standard package
2.  Continue until the dialog box [Package and Deployment Wizard - Included Files] is displayed
3.  Click the [Add] button and select msvcrt.dll
4.  The dialog box [Missing Dependency Information] will appear, click [OK]
5.  Progress until the PDWizard is completed.

There are no updates to the Alpha Edition of Visual SourceSafe in this Service Pack.
