Flickering

[Robot]

Hello,

I am creating an application using C# .NET.
In the main form is has got a few labels, panels,
buttons and treeView.
While changing size of window (by handling
right-bottom corner), everything is flickering in
horrible way. Each component is flickering in its
own way.

Of course, I set up doublebuffering:
SetStyle(ControlStyles.UserPaint |
ControlStyles.AllPaintingInWmPaint |
ControlStyles.DoubleBuffer, true);
UpdateStyles();

Unfortunatelly, it has not fixed the situation.

How to successfully set up doublebuffering?
I have read much about this, but did not find
any working solution.
Why doublebuffering set up by SetStyle
does not work?

Thanks in advance.

Double buffering only works for the individual window attached to each
control. You cannot double buffer the whole form.

You may be able to reduce the problem by managing the layout events.

I assume you are repositioning and resizing the controls on your form as it
is resized. Wait for Whidbey, maybe. Supposedly it will handle your case.

I had a similar problem and tried the same things. In my case, I developed a
user control in which I wanted its constituent controls resized in the
Designer. The code works but there is some flicker. The other thing I tried
that you didn't mention was to handle the Layout event. In the event handler:

this.SuspendLayout

// Resize and reposition controls

this.ResumeLayout
