    hello,
    just trying my hand at some winsock programming and i'm obviously missing something cause i keep getting errors such as:

    wsclient.obj : error LNK2019: unresolved external symbol _WSACleanup@0 referenced in function _main
    wsclient.obj : error LNK2019: unresolved external symbol _closesocket@4 referenced in function _main
    wsclient.obj : error LNK2019: unresolved external symbol _recv@16 referenced in function _main

    ok, the code i'm working with is taking from here

    http://frenchwhale.gotdns.com/winsockt/Lesson2.htm

    there is a #include <winsock.h> so why can't the linker see the functions???

    do i have to set special parameters for the project properties or something??

    im using VisualStudio.net btw

    any help or ideas would be appreciated,
    bostitch.

    Have you added wsock32.lib to your list of library files?

    Not sure if it's the same with .NET but in VS6 it's under Project->Settings->Link, the 'Object/libraries modules' box.

    added the file WS2_32.lib to the project properties under

    properties->linker->additional dependencies

    and it all seems to work sweet now!!

    You can also use pragmas to link to libraries in your source files.
    #pragma comment(lib, "WS2_32.lib")

    Sometimes I find this better when writing wrappers for Window stuff and don't want to have to add stuff to the project settings each time.
