You can do this with Windows XP, just not Windows 7. If I am understanding your inquiry correctly, you have to hold down the "Start" button key on your keyboard while dragging. You have to let go of the key on the keyboard before letting go of your mouse. Otherwise, your art will be deleted. Pull up a window (i.e. Microsoft Word) and shrink the window. You can drag this around, and use it as an "eraser" if you will. I hope that this is what you are looking for.

if you want to use the paint method then you should handle all repaint event and other complexities of GDI+ . but the easy way is to create a panel with borders on mouse click and when the mouse is moving change panel properties and with mouse release you will have the panel and your rectangle and no need to worry about repaint and ... .
