render OpenGL geomatry on dialog box button press

sorry if this is the wrong forum....it could be placed in either the game programming forum or the windows programming forum...but i decided to put it here...anyway, i have a dialog box, and when one of its buttons are pressed i wan't it to call a function that contains code for rendering 3D geometry (ie a cube).

my code:

Code:

---

BOOL CALLBACK InsertBrushDlgProc(HWND hWnd, UINT Message, WPARAM wparam, LPARAM lparam)
{
    switch(Message)
    {
        case WM_INITDIALOG:

        return TRUE;
        case WM_COMMAND:
            switch(LOWORD(wparam))
            {
            case IDSCUBE:                                       
                                glPushMatrix();
                                SolidCube(1.0, 1.0, 1.0, 0.0, 0.0, 0.0,
                                        FALSE,
                                        0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0,
                                        0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0,
                                        0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0);                               
                                SwapBuffers( hDC );
                               
                                EndDialog(hWnd, IDCANCEL);
                                break;

                        case IDHCUBE:
                                break;
                               
                        case IDCANCEL:
                                EndDialog(hWnd, IDCANCEL);
                break;
            }
        break;
        default:
            return FALSE;
    }
    return TRUE;
}

anyway on the button press it will not create the geometry....but i think somthing is happening, because when i press the button, my 3D grid which is rendered by default, changes color?

any help will be much appreciated!
