GL Control

I've made it work in the past, though I can't remember how. Basically I'm having glcontrol issues. The real problem is that I don't understand how it works in conjunction with threading, so I keep getting errors such as these:

Cross-thread operation not valid: Control 'glc1' accessed from a thread other than the thread it was created on.
Failed to make context 196608 current. Error: 170
Failed to swap buffers for context 196608 current. Error: 6

so my question is this: how does gl control work, and how do i ensure that i'm trying to access it on the same thread?

When rendering, you need to access it from the same thread as the Windows.Form you added it to, you can't use the GLControl in a background thread. You can however have a shared OpenGL background thread for rendering to a framebuffer or for loading resources etc.. but not an instance of GLControl, which must be on a Form.
