Viewing the OnMouseMove calls
Use a block like #ifdef BOGUS at the start and #endif at the end to temporarily comment out the CPopView::onMouseMove code inside the brackets and replace it with these three lines.
This way you'll see an X at each position where the mouse sends a an OnMouseMove call. Notice that if you move the mouse fast the X's are further apart. Also notice that if you resize the window after putting the X's in it they go away. Why is that?
The reason the three suggested lines look as they do is because you need to have a CDC object in order to call a 'graphics' function like TextOut. You can get a CDC from a CView using the GetDC function. The only requirement here is that when you get a CDC like this, you need to release it with a ReleaseDC call before leaving the block of code where you got the CDC.
