ethernet programming

I want to write a program in Visual C++ to transfer data between a computers and microcontroller via 10/100 Ethernet RJ-45.

What i need (libraries, or is there any help in MSDN.)

What i figured out is that i need "winsock" for programming.(TCP client and TCP Server)
Where should I start.

thanks

If you are using MFC, you should read up on http://msdn.microsoft.com/library/default.asp url=/library/en-us/vccore/html/_core_Windows_Sockets_in_MFC.asp.

Otherwise, http://msdn.microsoft.com/library/default.asp url=/library/en-us/winsock/winsock/wsasocket_2.asp is a good place to start, as it's got an example covering the basics.

MSDN would be a nice place to start. There are several examples there, which should give you an impression of where to go and what to do.

For a more comprehensive socket tutorial, you could turn to Beej. See http://beej.us/guide/bgnet/.

The ability to find the right technical documentation is a skill that one develops on ones own (i.e. try to refrain from using this forum to ask people to locate links to existing documentation). Also, please note that this forum is specifically for C++ language issues. I would direct this type of question in the Win32 newsgroups. In particular, this is the appropriate place for your question: http://msdn.microsoft.com/newsgroups/default.aspx dg=microsoft.public.win32.programmer.networks&lang=en&cr=US
