Can not activate the GL rendering context

OpenGL OpenGL: Basic Coding

Hi,

I am using OpenGL in my application under windows. I have strange error: Can not activate the GL rendering context.

It have worked until morning. I have not changed my code.

Why does it happen? And how can I solve it?

(I found that it happens on wglMakeCurrent).

Thank’s
Alexei
