Picture control

Hello all,

I am using the methods of the pic control (line, scale etc.) to draw lines on it.

Here's the problem: When the form containing the picture control looses focus, all the lines I have drawn dissappear !!

If I use API calls to do this, would I still have problem ? Any ideas ? (The use of the picture control is a must)

Hi, you have 2 options:
(1) Put all drawing commands in the PictureBox's Paint event, or
(2) Set AutoRedraw of PictureBox to true, before the drawing commands.

The AutoRedraw method would probably be the best method if your drawings occur at different times.
