What I'm trying to do:
I have a seperate window that displays parts of a bitmap to make a map. Image is attached:
I'm using the reverse video to show where the person is.
I've gotten all that to work. My problem is that only way I've been able to get the window to refresh itself is to use two ShowWindow commands to hide and then show. I've tried using SendMessage with a WM_PAINT but it won't redraw it.
