    unable to get gl context

    I need some help with these two related problems:
    Computer: Sony Vaio PCG-GRT170 Pentium(R)4 - 2.8GHz, Windows XP Home v2002 service pack 1, GeForce FX5600 graphics card

    1- Simple Opengl application under Visual C++ 6.0 Pro:
    Compiling: ok
    Linking: warning message "LNK 4098: defaultlib "MSVCRT" conflits with use of other libs; use /NODEFAULTLIB: library.
    I fixed that but it does not change so much.
    Executing: The program opens the window, the commands seem to be working, but it does not render anything.
    Debugging: I notice that the function wglCreateContext (...) returns NULL pointer, and the code error is 1114.

    2- Paradigm/Vega Marine application under Visual C++ 6.0 Pro:
    Compiling and linking: ok
    Execution: Vega return the following warnings and errors:
    => warn : Unable to get gl context for root window!
    => warn : OpenGL VENDOR: (null)
    => warn : OpenGL RENDERER: (null)
    => warn : OpenGL VERSION: (null)
    => fatal: jsWindow: Unable to get gl context!

    These two applications run perfectly in my desktop computer under Windows 2k, GeForce 4 and the same Visual C++ Pro.

    Does anybody have any idea what's going on??

    Thanks, David Sicuro

    This is an OpenGL ES specific discussion forum. You might have better luck asking on an OpenGL or Visual C++ newsgroup.
