OpenGL

Blender is a big project.
I have found a source unwrap in 3dkingdom.
I'm analyzing it.
My college started teaching C #.
I am moved to Csgl.

You can see my questions on CodeProject about OpenGL C + +
I follow the instructions of http://www.developerfusion.com/article/3930/opengl-and-c-part-1/

Now I have a few problems:
1. if I use Csgl, I need to copy. dll into app folder when running on another pc?
I think csgl is Refrences.

2. from the guidance of developerfusion, I added code to glDraw in OurView.cs

Cube obj = new Cube();
             obj.CubeColorBlue = 1.0f;
             obj.CubeColorGreen = 0.5f;
             obj.CubeColorRed = 0.0f;
             obj.glDrawCube();
             obj.Rotate = true;
             obj.fRotate = 1.0f;
             GL.glFlush();

but the result is cude not rotate.
I was wrong? in class Cube bRotateCheck = true;-> fRotate + = 2.5f;->glRotatef (fRotate,...)

3. how the width, height of view = 500.
I tried view.height = 500; view.width = 500.
but it still fill.
I do not want to fill because I need to use the control

Thanks for the help
