timegettime

Can someone help me figure out how to use TimeGetTime(); ?? Please.

You can use timeGetTime to get the duration between execution points as follows.

DWORD start = timeGetTime();
...... Do Some Job ......
DWORD end = timeGetTime();

DWORD ellapsed = end - start; // in milisecond unit

// CStopWatch.h

#ifndef CSTOPWATCH_H
#define CSTOPWATCH_H

#include <windows.h>
#include <mmsystem.h>

float Stop(); // stop stopwatch, return = number of seconds

private:
int Resolution; // set timer resolution in milliseconds (only effective on WinNT)

CStopWatch :: CStopWatch()
{
Resolution = 1;
StartTime = 0;
}

CStopWatch :: CStopWatch(int res)
{
Resolution = res;
StartTime = 0;
}

void CStopWatch :: Start()
{

#ifdef _WIN32
StartTime = timeBeginPeriod(Resolution);
if (StartTime != 0) throw(0,"Unable to set requested resolution","CStopWatch");
StartTime = timeGetTime();
#endif

}

float CStopWatch :: Stop()
{
float RT = 0.0;

#ifdef _WIN32
RT = (timeGetTime() - StartTime)/1000.0F;
StartTime = timeEndPeriod(Resolution);
#endif

return RT;
}

Add winmm.lib to linker settings if necessary

Note I would like this to work under MFC if at all possible. I would like it to function as a timer for a simple 2D animation. (I need more help understanding)
