Working with win 32 timers.
-
Hello All, I have a working timer in MFC can anyone tell me how to change it to Win 32.
MFC Timer Code. // Declarations #define ELAPSED_TIMER 101 time_t lStopTime; time_t lStartTime; CTimeSpan cteElapsedTime;//Start Timer time(&lStartTime); SetTimer(s->m_hWnd,ELAPSED_TIMER, 1000, NULL);//Kill Timer KillTimer(s->m_hWnd, ELAPSED_TIMER);//Timer Function void CSDlg::OnTimer(UINT nIDEvent) { if(nIDEvent == ELAPSED_TIMER) { time(&lStopTime); cteElapsedTime = CTimeSpan(lStopTime-lStartTime); CString csElapsedTime; csElapsedTime.Format("%02d:%02d:%02d", cteElapsedTime.GetHours(), cteElapsedTime.GetMinutes(), cteElapsedTime.GetSeconds()); if(IsWindowVisible()) { m_TIME.SetWindowText(csElapsedTime); } } CDialog::OnTimer(nIDEvent); }How to change it to win 32 application ?? what are the changes which I have to make in the below code????int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { // TODO: Place code here. INT_PTR mRet = DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAIN), GetDesktopWindow(), MainDlgProc); return 0; } BOOL CALLBACK MainDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam) { switch(Message) { case WM_INITDIALOG: { SetTimer(hwnd,IDT_TIMER, 1000,(TIMERPROC) NULL); } break; case WM_CLOSE: EndDialog(hwnd, 0); break; case WM_COMMAND: switch(LOWORD(wParam)) { case IDC_EXIT: EndDialog(hwnd, 0); break; case IDC_Start: //Starts the timer on button click break; case IDC_End: //Ends the timer on button click KillTimer(hwnd, IDT_TIMER); break; } default: return FALSE; } return TRUE; }Thanking you, Suresh HC -

You need to add one more case here,
case WM_TIMER:
if((UINT)wParam== ELAPSED_TIMER)
{
//do your stuff

Hi Prasad, Thanks for the response. In the declaration only I am getting error. But it is working in MFC. Hw to do it in Win32 ???

Its
MFCstuff. Usedifftimeinstead. See itsMSDNexample.Prasad Notifier using ATL | Operator new[],delete[][^]

Hi Prasad, No much information in MSDN. i got this link for win32 timers. http://msdn2.microsoft.com/en-us/library/ms632592.aspx

I was taking about difftime[^] example from

Prasad example gives the time diffrence only.
int main( void ) { time_t start, finish; long loop; double result, elapsed_time; printf( "Multiplying 2 floating point numbers 500 million times...\n" ); time( &start ); for( loop = 0; loop < 500000000; loop++ ) result = 3.63 * 5.27; time( &finish ); elapsed_time = difftime( finish, start ); printf( "\nProgram takes %6.0f seconds.\n", elapsed_time ); } -

difftimeis used as substitue forCTimeSpan.Prasad Notifier using ATL | Operator new[],delete[][^]
