WinForms controls are flickering when resizing on Windows7 x64

This very strange.

When I resize a WinForms dialog the controls are flickering very bad, some of them are disappearing. It happens only when using th开发者_如何学JAVAe application under Windows 7 64.

The solution for my problem is listed here:

Double buffering is disabled in Windows Forms by default, and unfortunately you get this flickering issue as a result. It's a pain, but that's the way that it is. You may want to read the following, or provide some more information about your situation if these do not solve the problem.

I had a similar problem with onResize event and I finally could fix it adding Invalidate():

protected override void OnResize(EventArgs e) {
 Invalidate();
 base.OnResize(e);

}

I know that redraw the screen each time the event happens is not the wished way to do it, but it worked for me.
