It almost sounds like your asking how to rubberband a line. If not, ignore my comments but if you are looking to have the bitmap drawn in your WM_PAINT handler and you want to stretch a line from some starting point to where the mouse cursor is, this is normally referred to as "rubberbanding".

Here's an old post of mine describing how to rubberband a line (btw, the idea is basically the same for a rectangle). Rubberbanding Lines[^]

NOTE: One you commit to the line being at some location permanently, you would need to keep track of that object and also draw it in your WM_PAINT handler but only after you no longer want to rubberband it. I reference the book by Ivor Horton which is truly a must have if your going to pursue a drawing project as he basically builds one in the second half of the book.

Also, this is all using MFC but the concepts can be easily adjusted to WIN32.
