James Zhou 2000: How to use Windows Timer API

Monday, November 25, 2013

To create a timer:

SetTimer(g_AppWindow, // handle to main window

IDT_TIMER1, // timer identifier

//1000/60, // 1/60-second interval

41,//1000/24, // 1/24-second interval

(TIMERPROC)NULL); // no timer callback

To use the timer to do sth:

case WM_TIMER:

switch (LOWORD(wParam))

{

case IDT_TIMER1:

// do sth here

// time your code

g_tick2 = g_pfnGetTickCount();

if (1)

{

WCHAR buffer[50];

swprintf_s(buffer, 50, L"Debug: %d ms passed ...\n\0",

(g_tick2 - g_tick1));

OutputDebugStringW(buffer);

}

g_tick1 = g_tick2;
