Вот так таймер работает:
| Код | int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int cmdShow)
{
SetTimer(NULL, NULL, MY_TIME_PERIOD, (TIMERPROC)MyTimerProc);
MessageCycle():
return 0;
}
VOID CALLBACK MyTimerProc(HWND hWnd, UINT uMsg, UINT_PTR idEvent, DWORD dwtime)
{
i++;
}
void MessageCycle()
{
MSG msg;
BOOL bRet;
while ((bRet = GetMessage(&msg, NULL, 0, 0)) != 0)
{
if (bRet == -1)
{
// handle the error anpossibly exit
}
else
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
} |
А вот так нет:| Код | int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int cmdShow)

Как организовать работу MyTimerProc?
