Timer

[geek@02]

Hi!
I'm having some trouble with creating a timer (for the 1st time) for my win32 dialog app. I tried to call SetTimer() from the dialog procedure, and created a Timer procedure for it. But it didn't work. The breakpoint inside TimerProc() never got hit. What i'm doing wrong, please?

INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
				   LPSTR lpCmdLine, int nCmdShow)
{
   DialogBox(hInstance, MAKEINTRESOURCE(IDMAINDLG), hWnd, 
			reinterpret_cast<DLGPROC>(DlgProc));
   ...............
   ...............
}

LRESULT CALLBACK DlgProc(HWND hWndDlg, UINT Msg,
			WPARAM wParam, LPARAM lParam)
{
   ...............
   ...............

   SetTimer(hWndDlg,IDTIMER1,1000,(TIMERPROC)TimerProc);

}

VOID CALLBACK TimerProc(HWND hwnd,UINT uMsg,
		UINT_PTR idEvent,DWORD dwTime){	

   ...............
   ...............

}

Try this

SetTimer(hWndDlg,IDTIMER1,1000,(TIMERPROC)&TimerProc  c);

Sorry it doesn't seems to work.
I also tried to call SetTimer() within WinMain(), and placed a WN_TIMER event handler in DlgProc(). But no luck either.

INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
   LPSTR lpCmdLine, int nCmdShow)
{
   HWND Dlg;
   SetTimer(Dlg,IDTIMER1,100,NULL);
  ..........
 }

LRESULT CALLBACK DlgProc(HWND hWndDlg, UINT Msg,
WPARAM wParam, LPARAM lParam)
{
   ...............
   switch(Msg){
   case WM_TIMER:
     switch(wParam){
     case IDTIMER1:
        .....
        .....
     }
     .......
   }
}

Wherever you declare your globals:

#define IDC_TIMER 600 /* Your choice for ID */
UINT g_unTimerRet;

In your message callback:

LRESULT CALLBACK WindowProcedure(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) {
     switch (message) {
          case WM_CREATE: {
               g_unTimerRet = SetTimer(hWnd, IDC_TIMER, 1000, &TimerProc);
               break;
          }
          case WM_DESTROY: {
               KillTimer(hWnd, g_unTimerRet); /* Don't forget to cleanup your mess! */
               break;
          }

Declare your callback for the timer (prototype) wherever you plan on putting the whole function. For example in main.c:

/* Prototype */
void CALLBACK TimerProc(HWND, UINT, UINT, DWORD);

/* The timer function that is executed every second according to when it was created */
void CALLBACK TimerProc(HWND hWnd, UINT uMsg, UINT idEvent, DWORD dwTime) {
     /* Whatever code you want executed here */
}

I know this works because I use it in my apps and I acquired it from MSDN.

Thanx.
