What is wrong with this code?

OpenGL OpenGL: Advanced Coding

I have been playing with different ways of creating different RC’s and wglMakeCurrent. This code will draw two different scenes onto two different forms. However, the second form is not redrawing correctly. I don’t have any animation so I don’t know if it is just drawing once and then stopping.
fullscreen = false 'never mind the next
two statements they just are part of NEHE
CreateGLWindow frm, 640, 480, 16, fullscreen
CreateGLWindow2 Form2, 640, 480, 16, fullscreen
wglMakeCurrent frm.hDC, hrc
Do While Not Done

        DrawGLScene
        SwapBuffers (frm.hDC)
        DoEvents
        DrawGLScene2
        wglMakeCurrent Form2.hDC, hrc2
        SwapBuffers (Form2.hDC)
        DoEvents
        wglMakeCurrent frm.hDC, hrc
        

    Loop

Looks like you’re drawing nothing in window2

try:
wglMakeCurrent Form2.hDC, hrc2
DrawGLScene2
SwapBuffers (Form2.hDC)

how can you have 2 fullscreen windows ?
