Erasing rectangle drawn with DrawRectangle

[Guest]

I want to use Graphics.DrawRectangle to draw a rectangle at a position on the
screen, and then a few seconds later, erase it. How do you erase a rectangle
that you just drew (without affecting the original background of the
window(s) behind the rectangle)?

Thanks...

If you force the background object (form, control, etc) to repaint
itself. You can use the invalidate method I believe.

Try ControlPaint.DrawReversibleFrame. Call it once to draw, call it again
with the same args to erase. The disadvantage is that you can't precisely
control the rectangle's color.
