I have used windows time(VC++)r to call my function at interval of 11 millisecond but when I print time in my callback function I found out that it is not getting called at interval of 11 ms but it is getting called at 15-16 milliseconds. If I give interval as 17 it is getting called at interval 31 to 32 milliseconds.
I dont know why this is happening??

then I have called similar function in C# on same machine, it also shows same interval. I am using Intel Core to Duo machine with 2 GB RAM.
When I read timer MSDN I found out that it gives acceracy upto 10 milli second.
Can Anybody suggest me proper solution to my problem so that it can get accuracy upto 10 millisecond.
Thank you in advance for your help.

Windows timers generally run off the hardware timer, which has a resolution of 10 - 15ms (depending on the hardware, most run at 15.6ms intervals) so when you ask for a lower interval, you get an accuracy of 10ms in teh timer value, but a resolution of 15ms in the timer interval.
