In VB what is the difference in hDC and hRC?

[John Jenkins]

I know it is a VB question but it is very important for OpenGL programming.

Judging from those variable names, I'm guessing hDC is an HDC and hRC is an HGLRC. The difference is that the HDC is a handle to the device context for the Window, and the HGLRC is a handle to the rendering context for OpenGL.
