Hi,

can someone tell me how to reduce/eliminate the flickering and speed up redraw in this project.

http://dl.dropbox.com/u/18687229/Versions.7z[^]

I've been fiddling with:
userpaint
doublebuffer
suspendlayout
begin resize / end resize

The custom controll GradientGroupBox is working perfectly in some other projects I made, so I don't think this is the problem.

Can someone help me with this one.

Thnx

This is a common problem with common mistakes. Your attempts look correct, but may be insufficient. Please show some code (minimize it but keep it 1-compiling, 2-manifesting the problem)

Solution 1

Use double buffer wherever you make graphics operations in the paint event.

Comment from OP:
As you can read in my question, I've already tried this.

Yes, I have read your question, but I have done this kind of work countless times and so I do know you just have to use double buffer to avoid flickering, so maybe you are not using double buffer in the right places. Just want to put you in the right direction.

I've tried double buffering in all places, no improvement. Take a look at the code if you have the time.

Thnx
