Hello,

EnumChildWindows is defined as follows:
   BOOL EnumChildWindows( HWND hWndParent, WNDENUMPROC lpEnumFunc, LPARAM lParam ) ;

With C++Builder 5, I used the following call:
   EnumChildWindows( HANDLE, EnumFunct, PARAM ) ;

That does't work with BDS2006, I have gotten the following error message:
   [C++ Error] ...: E2034 Cannot convert 'int (__stdcall *)(void *,long)' to 'int (__stdcall *)()'
   [C++ Error] ...: E2342 Type mismatch in parameter 'lpEnumFunc' (wanted 'int (__stdcall *)()',
                          got 'int (__stdcall *)(void *,long)')

After casting EnumFunct as WNDENUMPROC
   EnumChildWindows( HANDLE, (WNDENUMPROC)EnumFunct, PARAM ) ;
compiling was successful.

Any comments would be highly appreciated!


Thanks and greetings
Udo
