OpenGl inside MFC

[Baguette]

Hello,I'm trying to create a MFC app with OpenGL. I followed a tutorial posted on CodeGuru(I can't find link to it, but if someone want it I will try to find it), but my app didn't work properly-the field with OpenGL control was black and there weren't any shapes witch i wanted to draw. So i switched to different guide(http://steinsoft.net/index.php?site=Programming/Tutorials/opengl_dialog),and i
got same problem. I tried to use "copy/paste method" and again same thing.
I'm using Visual Studio 2010. I'll be grateful for any help.
