Bitmaps and threading model

[WRH]

Hello
I have a Form where I display DirectX Direct3D stuff on one panel
and a WebBrowser in another. Compiles & runs fine until I add
one line...

private Bitmap bmpForm= new Bitmap(typeof(Form1), "frame5.bmp");

Compiles ok, but does not run... I get a System Thread Exception
where I instantiate the web browser...
"Could not instantiate ActiveX because the current thread is
not in a single-threaded apartment".

Does loading a Bitmap change the threading model? What should
I do to get my bitmap?

WRH,

I wouldn't create the bitmap in the declaration. Rather, try it when
the form loads, after the window and the webbrowser control is created.

Hope this helps.

That did the trick! Thanks.
