    Not drawing to rendering context...

    ok, this is a new problem with my wrapper class for opengl initialization, nothing can get drawn to the rendering context.
    no compiler errors/warnings, Everything loads up fine, I can clear the background color fine, however I cannot draw anything to screen. I have included the project, as I cannot find out where it is at, even though all my initialization code etc. looks fine(yes, i did check for same names in functions this time )

    edit:

    havent implemented anything with the keyboard yet, so ALT+F4 is the only way to close it currently.

    What are you using for rendering code?

    Code:
    void Render()
    {
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glLoadIdentity();
    
    glTranslatef(0.0f,0.0f,24.0f);
    glBegin(GL_TRIANGLES);
    glVertex3f(-1.0f,0.0f,0.0f);
    glVertex3f(0.0f,1.0f,0.0f);
    glVertex3f(1.0f,0.0f,0.0f);
    glEnd();
    
    
    SwapBuffers(g_EchGL.g_hdc);
    };

    glTranslatef(0.0f,0.0f,24.0f);

    should be
    glTranslatef(0.0f,0.0f,-24.0f);

    that works, i was under the impression though that gltranslatef worked in reverse, i.e. gltranslatef(6.0f,0.0f,24.0f) would move it 6 unites to the left and 24 inward. I really need to practice more, my current school schedule is killing my programming ability. not only is it killing my programming ability its almost killing me. I have almost committed suicide(chickened out cause i dont like the sight of my own blood) this past month trying to make sure I have a 4.0 GPA.

    I figured that was your problem. I did the same thing one time and got frustrated, until I figured it out.

    edit: I remembered last year telling myself "Next year I'll hit the books and get a 4.0 GPA all throughout the year." I then realized why I have never kept a 4.0 GPA in high school, once the year started. I had a 3.5 last quarter, and I think I'll get like a 3.6 this time. Mid-terms should bring them both up though. The only reason my grades are as a low as they are is because I don't do homework. I've turned in a total of 10 assignments this quarter, and the quarter only has 2 more weeks.
