I'm using OpenGL with visual basic and i'm trying to do something that i don't know if it is possible to do.
I need to draw points on a picturebox with an image.
The problem is that i'm not able to draw anything on top of an existing image, because OpenGL Clears everything on the picturebox
I've allready tried to play with
glClear
and
glClearColor
but nothing useful happened
Can you help?

My thanks in advanced
