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