• Visual Studio Express Editions How to create an Icon image file

• Windows Forms OpenGL control

  Hello everyone ! I'm new to windows forms ( actually I started kinda...today)...  I was able to bind an OpenGL context to a form, and later create a GLForm derived from Form.

Is there any way I can "pipe" the output of one datareader t ...Show All
