beginner's problem

Hello! I''m working on creating some separate ("generic") files to use for a few projects I have in mind, but have come to a really easy sounding obstacle. I can''t get the OpenGL window to clear itself or change the background color to black. In fact, whatever is on my screen at the time is what shows up in the OpenGL window. It works pretty much like a "screen capture" utility, but without a save feature... At any rate, I''m wonder how to overcome that. I have 2 files thus far... The main one for WinMain and for user input (using Win32 stuff), and the other OpenGL class for creating the window and supposedly clearing out the window and making the background black. For a better glimpse at how this is working, this is how I create the actual window from the main file: screen.makeOGLWindow(WINDOW_TITLE, WIDTH, HEIGHT, COLOR_DEPTH, false, &hWnd, &hdc, &hrc, WndProc); Anyway... that''s the problem. Window shows up, but it never clears. Any ideas?

Good news! It works now! Yay! I noticed that everything went R E A L L Y slow when I tried the screen.draw() in the loop, and realized it''s ''cause I put it in the wrong spot...hehe.. whoops! But it''s working soundly, now.

Also, if you set the window.hbrBackground to the BLACK_BRUSH, OpenGL *can* still change that value. But I set it back to NULL, just ''cause I''m a scared sissy. =)

Thanks everybody... only a few more months until my engine rivals the power of Wolfenstein... especially with me at the coding helm....

Onward with progress. =)
