Add WinSock (Not winSock2 ) Class into


  • Hi To all,

    I need to add winsock class into my Project.plz tell me how to add  old winsock class into my 2008...

  • VC.Net is just an IDE. The winsock.h file is in Windows SDK. Refer to Windows SDK documentation like "using windows headers" for proper usage of Windows SDK files. If you need more help in using Windows SDK files, ask in the Windows SDK forum.
