Hi Andrew,

Thanks for quick reply. I am able to configure the Performance
Counter, but my application is hanging when i try to use it. The code
which i am using is as below.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

LARGE_INTEGER liDelay;
// Query number of ticks per second
if (QueryPerformanceFrequency(&liDelay))
{
// 1ms delay
liDelay.QuadPart /= 1000;

LARGE_INTEGER liTimeOut;
// Get current ticks
if (QueryPerformanceCounter(&liTimeOut))
{
// Create timeout value
liTimeOut.QuadPart += liDelay.QuadPart;
LARGE_INTEGER liCurrent;
do
{
// Get current ticks
QueryPerformanceCounter(&liCurrent);
// Delay until timeout
} while (liCurrent.QuadPart<liTimeOut.QuadPart);
}
}

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

liDelay.QuadPart /= 1000; // for milli seconds divide by 1000
liDelay.QuadPart /= 1000; // for second divide by 1

The statement i am varying according to my requirement. But only thig
is when i am trying to get microseconds delay with this code, my
application is getting hanged and it is terminating itself. Any
suggestion from you will be a great help to me. Hope you understand my
problem.

With warm regards,

Chandra.
