    how do i "link the winsock library??"

    In the tutorial
    http://www.hal-pc.org/~johnnie2/winsock.html
    it says this:

    "Remember that any code presented in this tutorial should be linked with the Winsock library, usually wsock32.lib or something similarly named."


    how exactly do" i link the winsock library??"

    #include wsock32.lib???
    #include wsock32.h??

    doesnt work

    wsock32.lib's in binary
    using vc++ 6.0 btw

    Add your library to the list already there

    You can do that, but I prefer to use this (before #including winsock.h)

    Code:
    #pragma comment(lib, "wsock32.lib")
    Only because it makes it easier to transer code from IDE to IDE (or compiler). Also because I hate going from mouse to keyboard alot.

    What makes you think ANO compiler will pay any attention to that pragma?

    Well it works with VC and I'm pretty sure it works with DevCpp. Besides, I use it mostly so that I don't have to mess with windows and go right to typing.

    Besides, when working with other people, if it does work, then they won't have to mess with settings and if it doesn't work, then it should be a clue that they have to mess with settings.

    > unresolved external symbol _main
    Your code begins with winmain(), which is a GUI project

    But you've set things up to be a console project which always starts at main()

    That pragma is not supported by GCC (unless it changed recently). Since DevC++ uses gcc ("mingw") I would think that it won't work.
    Generally, stuff in a pragma is non standard and should be used with caution.

    Personally, I would love to see a preprocessor command to link a library included in the standard.
    I still dream of C++ unit-support to get rid of seperate header files and libraries...

    The other problem with tricks like this
    #pragma comment(lib, "wsock32.lib")

    Is what do you do when you want to link with a debug library in a debug build, and a release library in a release build.

    Let me see now, I know, I'll put the correct name for the library in the link options for each type of build.

    >>#include <winsock.h>
    Since all Windows versions from 98 up support Winsock2, and 95 can get the upgrade, I'd suggest using winsock2.h. Also, then I think you need to get rid of the #include <windows.h>, to avoid redefinition errors - if it works on your computer, fine, but if you get those weird errors, you'll know where to look (winsock2.h completely replaces windows.h I believe).

    >>Is what do you do when you want to link with a debug library in a debug build, and a release library in a release build.
    Just link the release build then... But seriously, I never even knew that there were such things as "debug libraries"

    I'd suggest doing whatever you like... I personally usually use #pragma, because then it gets linked if/when I include my header file for my sockets class, meaning I need about 6 fewer mouse clicks and quite a bit fewer keyboard strokes to get started with using Winsock in my program Of course Salem, what you said has validity too, but I'm too lazy to bother with The Tab.

    Which is my preference, I thought was clear, but, yea, so, yea.
