Can someone tell me why I get this error when trying to compile this code using VC++ 5.0? error C2664: ''SetTimer'' : cannot convert parameter 4 from ''void (void *,unsigned int,unsigned int,unsigned long)'' to ''int (__stdcall *)(void)'' ##################### CODE ################################### int PlaySnd(void) { SetTimer(hwndMain,PLAYBUTTON_TIMER_ID, nSndSampleLen,PlayTimerProc); return 0; } VOID CALLBACK PlayTimerProc(HWND hwnd,UINT message, UINT iTimerID, DWORD dwTime) { // Stuff..... } ###################### END OF CODE ############################## Thanks

Timer call backs dont (ie cant) take any parameters, and return as int

    //no ah ahVOID CALLBACK PlayTimerProc(HWND hwnd,UINT message, UINT iTimerID, DWORD dwTime)int PlayTimerProc(){return(false);}

You will need to use a cast on the last parameter of the SetTimer function, ie do this:

SetTimer(hwndMain,PLAYBUTTON_TIMER_ID, nSndSampleLen,(TIMERPROC)PlayTimerProc);

Hope this helps.

good question ha ha :-)

I like game very much, so I want to make more people like it !

Thanks for your suggestions...

I downloaded the latest Platform SDK from
Microsoft that includes the lastest headers
and libs. That fixed the problem. My code
now compiles as is.

Thanks again.
