Periodic function

I'd like to execute a function at 100Hz. IOW, every 100Hz I'd like to call say a 'foo' method. At issue: I only have Visual Studio Express (2005 and 2008). My research thus far suggest that I'm not able to use the Windows API suite (SetTimer, CreateEvent etc. etc ). True/False?

Is it possible then to achieve my objective via QueryPerformanceCounter or std::clock?

Thanks in advance

True. The standard windows timers can't even come close to what you want.

Hz is not a unit of time. Your question doesn't make sense.

The meaning is clear despite the incorrect units. Every 10 milliseconds = 100Hz. And yeah, you'll need a kernel-level interrupt mechanism to guarantee that sort of granularity.

I might have a follow up question on this, nonetheless, thanks Alin, Skizmo and Lindley.

Programming is an exact science. Using the correct terminology is important.
