    `SetCooperativeLevel' undeclared (first use of this function)

    I am getting gobs of errors with this script:

    Code:
     IDirectDraw4::SetCooperativeLevel(hwnd, DDSCL_FULLSCREEN | DDSCL_ALLOWMODEX | DDSCL_EXCLUSIVE | DDSCL_ALLOWREBOOT);
    It doesn't like anything I have in the second argument,
    Plus it doesn't even recognise the SetCooperativeLevel() function. Why is this?

    The function doesn't exist
    You spelled it wrong
    You got the capitalisation wrong
    You chose the wrong build options (maybe it's conditionally compiled in)

    Find the function in the header file, check it's spelling, which class it's a member of, whether there are any #ifdef surrounding the function.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    As far as I remember, this function is not static. You need an instance of a class implementing IDirectDraw4 to call this function.

    Maybe you could consult a newer tutorial, DD is up to version 7 with a standard install of Win2K. The problem you have will persist though, it's a coding issue, not a version conflict.

    She was so Blonde, she spent 20 minutes looking at the orange juice can because it said "Concentrate."

    When in doubt, read the FAQ.
    Then ask a smart question.
