Hi... I have a dialog based MFC app. In OnInitDialog, I start a timer with 1000msec delay. I use the standard SetTimer. Whenever the time passes, I call WM_TIMER and run an algorithm. My question is this: the algorithm I run is very important and needs to be precise. But WM_TIMER is a low priority message. How do I improve the accuracy, or how do I make the message more high priority? I want to try avoid multimedia timers because I have tried them and got lost. Standard SetTimer is nice and simple.
