Re: [Csgl-users] CsGL.Util.NativeException was unhandled. Message="The pixel format is invalid.

[<Hai...@co...>]

Hello,

I found out that the application has "The pixel format is invalid"
exception that caused byt he following line. As soon as I take it out the
3D chart works fine. Any body has any idea why MdiParent cause the problem?
What should we do if we want to keep the following line?

myResultForm.MdiParent = this;

Thank you,
Haiping
