PRB: Functions of the VC++ WPL May Not Respond as Expected (155190)
The information in this article applies to:
- Microsoft Visual FoxPro for Macintosh 3.0b
This article was previously published under Q155190 SYMPTOMS
When building a library of C functions to access with Visual FoxPro for
Macintosh (with the SET LIBRARY Command), you may choose to use the
Microsoft Visual C++ (VC++) compiler, which offers a set of functions (the
Windows Portability Library, or WPL) that may be ported to the Macintosh.
These functions may not work as expected or desired when loaded under
Visual FoxPro for Macintosh.
CAUSE
Visual FoxPro for Macintosh was not designed to work with the functions of
the Windows Portability Library. Many of these functions allocate
memory outside of FoxPro, which is something that is not recommended within
a library that will be loaded from FoxPro.
WORKAROUND
Use functions provided in the FoxPro API Library or the Mac Toolbox.
You may also be able to create a stand-alone application, using the
functions of the Windows Portability library, that may be run from Visual
FoxPro via AppleScript, using the FoxPro RUNSCRIPT command.
STATUS
Microsoft is researching this behavior and will post more information in
the Microsoft Knowledge Base as it becomes available.
