Exception error in the statement

                  GL.glMatrixMode(GL.GL_MODELVIEW);
                  GL.glLoadIdentity();
            }

and which exception?  "division by zero"? if yes, check that "s.Height" is not zero in protected override void OnSizeChanged(EventArgs e)

please wait I will check it by opening my file

type initialization exception was hadled in the statement  base.onchanged(e)

I am running the above Csharp program in  VS2005 ....I am getting the error message as

Type initialiazation exception for csgl.OSLib unhanled

can you show the code of base.onchanged(e) and the line the exception was thrown?

the jpg file
pic.jpg

can you click "view detail" and post it here?

view details
pic2.jpg

it says: "the dll csgl.native.dll could not be found"

did you install csgl properly?

Could you tell me the exact procedure what I have to do
to install csgl in your project

post-overlapping .. check my last comment ;)
