SYMPTOMS

This patch fixes two different Visual C++ 4.1 problems described below.

  • It fixes a problem you may be seeing in an MFC application that uses the Microsoft database classes. While using certain ODBC drivers, you may get "Out of memory" errors. See below for a list of files updated.

    For more information, please also see the following article in the Microsoft Knowledge Base:

          TITLE     : FIX: Run Out of Memory or Assertion in
                  GetBufferSetLength()


  • It also fixes the debugger problem in the Microsoft Developer Studio
   where you may not be stopping at breakpoints you have set if your
   project was built from a directory structure that contained long names.
   This problem did not exist in Visual C++ 4.0. See below for a list of
   files updated.

      MORE INFORMATION
      
 

      
Several of the MFC files that will potentially get patched are optionally
installed.  You may get a message in the patch log stating that a
particular file wasn't found and that is OK.  If you didn't install the
Unicode MFC libraries for instance, the patch program won't find them.

      
For any other potential problems and resolutions, please refer to the
readme file in the patch.
