    In part. You need to interrogate the system for the current user name (look up GetUserName() in the win32 SDK). "..../&#37;USERNAME%/Local Settings/Temp" is also a directory; you need to append a filename to the path.

    GetUserName() in the win32 SDK has two arguments (a pointer to a buffer that will receive the username, and the length of that buffer) and returns a BOOL (zero for failure, non-zero for success). You are presumably using some other library.

    The username needs to be substituted in where you have &#37;USERNAME%, and (for example) a filename named file.dat needs to be appended on the end of the path (so if the user is "grumpy", the filename will look like "C:/Documents and Settings/grumpy/Local Settings/Temp/filename.dat"

    ok


    when compiling i get the following error
    error C3861: 'GetUserName': identifier not found

    is this because i havnt got
    #include <windows.h>

    if i add that
    i get this error
    fatal error C1083: Cannot open include file: 'windows.h': No such file or directory

    is this because im using the visual C++ express edition ?

    Could be; I've never used the express edition, so don't know its shortcomings relative to the flagship products.

    You may need to specifically specify the include path which contains <windows.h>. I don't know how to do this with Microsoft compilers. On the other hand, maybe that compiler doesn't even have those functions.

    You could always try a different compiler.

    Yes - You need to instal Windows SDK and add paths of SDK include, library and executable directories to your IDE settings -
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    >> ok ty i will look into getting a diffrent complier

    Why? Just finish installing the VC++ Express. Part of the installation process is to download the SDK separately.

    because im asuming that with other compliers you will be also allowed to make win32 applications

    with this i can only make win32 console applications and windows forms applications

    No, you can also make Win32 windows applications without forms.

    I think you're looking for a resource editor, which VC++ has. I'm not sure about express, though.
