c# winform drawn image flashing

Question

I have a image drawn in an winform app and i designed a brush that moves after the cursor. The Brush is drawn every time so the image keeps flashing because the image is also redrawn . How can i avoid this ?

Answer 1

Simply set the form's DoubleBuffered property to true. That should solve the flickering.

No reason to make it more advanced than this, in such a simple scenario.

Answer 2

Use double-buffering. Draw each frame to some kind of memory bitmap representing the back buffer and once it's drawn show it on the first.
