    	MessageBox(NULL,msgbuf,"Error",MB_ICONERROR);
    }
    This didn't help me at all, I want to display the error as a string, not a #. Thanks though.

    Hunter, I'll see what I can do with it.

    The supplied code will display the error message associated with the supplied error number.

    Code:
    bRet = ReadFile(...);
    if (!bRet) {
         DisplayError("Some Context.", GetLastError() );
    }
    Sample output:
    Some Context.
    Windows Error 38: Reached the end of the file.

    Alternatively you can write a thousand plus switch case with the error messages and numbers found here:
    http://msdn.microsoft.com/library/en...rror_codes.asp

    Please consider actually trying the code.

    Have Fun!
