Get A Timer That Runs A Process Every 31.25 Milliseconds?

I'm in need of a timer that runs a process every 31.25 milliseconds. Thus, after 768 "ticks" have gone exactly 24 seconds.The control "Timer" that exists in Visual Studio does not accept decimal values.So I had to round the value of the range to 31 or 32. But this raises a problem since the end of the 768 ticks there is a difference of half a second or more. And I need to run the 768 ticks in exactly 24 seconds.I've been researching, and I read some things about the "High-Resolution Timer. " But I did not understand exactly how to use it, and how to set your interval to 31.25 mils, and do that every period of this interval to run the code.
