The type initializer for 'CsGL.OSLib' threw an exception.

Alexandr Dermenji — Sun, 27 Sep 2009 17:42:24 -0000

Hi.

I'm really new to OpenGL. I was programming on a x86 computer and my applications run fine, but recently i moved to a x64 machine, and it throws the following exception: "The type initializer for 'CsGL.OSLib' threw an exception." Please, help me deal with this issue?

Here is the part of code where the exception is thrown:
protected override void OnSizeChanged(EventArgs e)
{
base.OnSizeChanged(e);
Size s = Size;

GL.glMatrixMode(GL.GL_PROJECTION);
GL.glLoadIdentity();
GL.gluPerspective(45.0f, (double)s.Width / (double)s.Height, 0.1f, 100.0f);
GL.glMatrixMode(GL.GL_MODELVIEW);
GL.glLoadIdentity();
}

It is thown on the first line: base.OnSizeChanged...

Model Import Problem

Hi! Hope youre having a good time.

Im sorry to bother you with such nonsense
(as you may see this) but Ive got some big trouble
that Im unable to solve by myself. Ive already tried
to solve it trough friends, professors, programmers,
mailing lists and almost any way I thought of. However,
Ia afraid I came out with the necessity to ask you for
help.

Im using the ObjReader you wrote, along
with the ObjModel. In ObjModel there is an DisplayList
called obj which contains the list generated by CsGL.
This obj object contains an attribute called Base,
which is used lately in the Init method as parameter in
GL.glNewList. However, obj.Base (which is a uint)
generates an exception. I guess its improperly
initiated when the obj object is constructed. However,
it is inaccessible. The question is: How can I correct
this error? Id love to get the source code of a simple
functional program which uses these .cs classes, since
Ive been unable to find any example on how to use
them. Hope you can help me, since this is beginning to
get on my nerves. Thanks a lot.

Greetings,

Gabriel Hernandez.

Weird problem with texture mapping

Anonymous — Thu, 09 Oct 2003 20:41:51 -0000

Hello,

I am having a problem texture mapping. I have derived
a control from OpenGLControl and have put an instance
on a form. The instance has an OpenGLTexture2D
object with a texture stored in it that I use to texture a
square polygon.

You can rotate the polygon using the mouse and left
mouse button.

You can change the polygon by pressing the F1 key and
browsing your file system for a specific texture.

I use the following code to implement my rotation.

base.GrabContext();
GL.glMatrixMode(GL.GL_MODELVIEW_MATRIX);
GL.glPushMatrix();
GL.glLoadIdentity();
GL.glRotated(alpha, axis.x, axis.y, axis.z);
GL.glMultMatrixd(rotMatrix);
GL.glGetDoublev(GL.GL_MODELVIEW_MATRIX, rotMatrix);
GL.glPopMatrix();

The problem I have arises when I do a rotate and
change the texture. If both of these things have been
done, then on my call to m_texture.Bind() I get an
exception "invalid enumerant".

I have attached the source for a simpe application that
has the problem. I am not a beginner with OpenGL and
have troubleshot this for a while. I'm not sure if there is
a bug in the wrappers or if it's in my code. If someone
could please look at this problem and help me out it
would be much appreciated.

If you would like to contact me directly my email
address is Drew.McLean@__nospam__cedara.com with
the __nospam__ removed.

Thanks in advance.
