    Read this.
    Use WinMain instead of main (search for it on the above).
    Also read up on window procedures (WindowProc) and message loops.

    Failing that, post some code, ideally in the Windows Programming board.

    Where, in your code? As far as I know there's no requirement of main2 for anything, so it's probably just a badly-named function.

    this is its first appearance
    Code:
    int main2(int argc,uchar *argv[])
    { 
    lots of code 
    }
    and then here

    Code:
    // bic -> int main(int argc,uchar *argv[])
    int WinMain(int argc,uchar *argv[])
    {
    #ifdef PROTECT
        // REMOVED: exe integrity check
    #endif
        return(main2(argc,argv));
    }
    i guess its a func specific to this program that doesnt need to be changed? =)
    im a newb, sorry =)

    That appears to be a passthrough, in that it passes the arguments used to start the program (main) directly to this second function main2. Really though, I wouldn't do it like that. This "EXE integrity check" thing should be stored in a function rather than clogging up main (Which, I'll have to assume, was the reason for main2).

    You should be able to cut the code from main2 and paste it into main, deleting main2 in the process.

    Also, WinMain is defined in the MSDN library as:-
    Code:
    int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow);
    It's not a case of just changing the name of the function, these arguments are specific to Windows. If you get errors after making this change, have you included windows.h (i.e. "#include <windows.h>" should be at the start of the code)?

    Great. Now how about you take the first error or warning, and fix that. Repeat that process until all of your errors and warnings are gone.

    Oh, I suppose you expected me to pull the answer out of my ass or something, right? I mean really, you didn't expect us to provide you with an answer just because you gave us the number of errors and warnings, did you?

    You did, didn't you? Now that's just sad.

    Hope is the first step on the road to disappointment.

    Simply renaming your DOS 'main' into a windows 'winmain' isn't going to make it any less DOS-like than it already is.

    More likely, it simply isn't going to work as you would expect, since windows programs are fundamentally different from console programs.

    Your best bet is to locate some particular magic on the net somewhere which allows you to wrap up DOS programs as a win32 service.
    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.
