I've been using the CMfcOglView class provided with the
Microsoft MFCOGL with great success.

But now I want to create 2 or 3 OpenGL context regions
all within the same Window. How would I go about doing this?

This routine goes right into setting up the OpenGL context
without even giving me a chance to specify/setup other windows:

void CMfcOglView::Init()
{
	PIXELFORMATDESCRIPTOR pfd;
	int         n;
	HGLRC		hrc;
    m_pDC = new CClientDC(this);
    if (!bSetupPixelFormat())
        return;
    n = ::GetPixelFormat(m_pDC->GetSafeHdc());
    ::DescribePixelFormat(m_pDC->GetSafeHdc(), n, sizeof(pfd), &pfd);
    CreateRGBPalette();

    // create a rendering context and make it current
    hrc = wglCreateContext(m_pDC->GetSafeHdc());
    wglMakeCurrent(m_pDC->GetSafeHdc(), hrc);

Any help would be greatly appreciated.
