BUG: Incorrect prototype for VDMStartTaskInWOW()in VDMDBG.H file
The information in this article applies to:
The function declaration for VDMStartTaskInWOW() API in VDMDBG.H is missing the WINAPI keyword as follows:
BOOL WINAPI // this keyword is missing in vdmdbg.h VDMStartTaskInWOW( DWORD dwProcessId, LPSTR lpCommandLine, WORD wShow );
Without the WINAPI or PASCAL keyword, the Visual C++ Linker looks for the symbol _VDMStartTaskInWOW, which is not available in the VDMDBG.LIB. With the WINAPI keyword, the Linker looks for the correct symbol, _VDMStartTaskInWOW@12 and finds it.
Fix the prototype in your local copy of VDMDBG.H file as follows:
BOOL WINAPI VDMStartTaskInWOW( DWORD dwProcessId, LPSTR lpCommandLine, WORD wShow );
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
