if i want to draw something on the control, then how can i do it?
For example, when i call function named WriteSomeThingOnPanel(),

Then there will be a line drawn on Panel?

I have tried to get the Graphics of the Panel by
Graphic.FromHwnd(panel.Handle);
then draw the line, but nothing can be drawn?Thanks


You use the Paint event, just as in the code that you posted. The event arguments contains a reference to the graphics object that should be used for drawing, just as in the code that you posted.

To trigger the Paint event, you call the Invalidate method on the control.
