In Visual Basic looks like that: glReadPixel xpos, ypos, 1, 1, rpRed. pxlByte, Variable How do you make new date type to make "pxlUnsignedByte" instead of pxlByte? Reason I asked that is because pxlByte output is 0 to 127 and it discard any minus number in VB. I think it is final problem for VB with OpenGL Waldoo

Public Const pxlUnsignedByte &H1401

Shove that in a module somewhere and you should be able to pass that to glReadPixels.
