Problem


zApp does not build sucessfully using MSVC 6.0.


Cause


zApp build fails with the following error:

D:/spm7_patched/parts/zap0310wsourcesrcdispinfo.cpp(190) : 
error C2664: 'EnumFontsA' : cannot convert parameter 3 from
'int (__stdcall *)(void)' to
'int (__stdcall *)(const struct tagLOGFONTA *,const struct tagTEXTMETRICA *,unsigned long, long)'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast
NMAKE : fatal error U1077: 'cl' : return code '0x2'
Stop.



Action


In the file dispinfo.cpp in spmpartszap0310wsourcesrc, change line 186 from:

   EnumFonts(hDC, faceName, fp, (LPARAM)p);

to

   EnumFonts(hDC, faceName,
(int(__stdcall*)(const tagLOGFONTA*, const tagTEXTMETRICA*, unsigned long, long))fp,
(LPARAM)p);

The entire function should look like:

RWTPtrSlist* zDisplayInfo::getFontList(char *faceName) {
lock();
RWTPtrSlist *p = 0;
if (hDC) {
p = ZNEW RWTPtrSlist;
FARPROC fp = MakeProcInstance((FARPROC)fontGrabber, zAppGetAppVar(app)->instance());
EnumFonts(hDC, faceName,
// Just typecast param 3 to what the compiler wants callback to look like
(int(__stdcall*)(const tagLOGFONTA*, const tagTEXTMETRICA*, unsigned long, long))fp,
(LPARAM)p);
FreeProcInstance(fp);
}
unlock();
return p;
}

Save the file and rebuild the library. It should now build successfully.

IMPORTANT: Using zApp with MSVC 6.0 is not supported by Rogue Wave even if this change is made to the zApp source code.
