C++ windows pause timer

I'm using SetTimer to create a timer in my application with an interval of 50ms, this timer is going to be used to draw an object, and move it around.

Now I don't want the object to move when the window is out of focus, but I still need it to be painted. And having it paint every 50ms, seems unnecessary. And performance is extremely important in this project.

So I need a way to pause the timer, but still draw the object, but preferably only when needed.

Just a note aside to you initial problem.
I would not rely on Windows Timer with such low resolution. It's a low priority message and if you have lots of heavy duty things going on in you program, the timer might be invoked at higher intervals that you expect.

When you get WM_ACTIVATE, decide whether to call KillTimer or SetTimer.
