thanks for your support.. i have written simple client server program in vs2008 using winsock.h with the help of tenouk.com/Winsock/Winsock2example2.html and it's work fine.but the problem is that i have to generate a http url for server on which the client open that and send the data to server. i can't understand how client communicate with http url and how the data received by server just by opening that url by client.user1196792– user11967922012-03-05 10:06:18 +00:00Commented Mar 5, 2012 at 10:06

From reading the comments, it sounds like you're going in the direction of using sockets directly. Don't do that. Use an HTTP client library. The basic HTTP protocol is simple enough that the sockets approach is workable for a rudimentary client, but you won't support features like HTTP keepalives, proxy servers, encryption (https), HTTP/1.1, compression, chunked encoding, or 100 continue without completely reinventing the wheel.
Use libcURL. When writing in C, uploading a file to an HTTP server is only a few dozen lines of code, including boilerplate.

If you want to send a file, read up on the PUT method. In its simplest form you can just send the method, the headers, a blank line, then the contents of the file, then close the socket. But libcurl will do all of this and more for you and it will be a lot less work and more compatible. You didn't explain your objection to using libcurl or another HTTP client library.

ya we can use libcurl for sending file to server but how http server received it there end.what we do for receiving from server .i m using vs2008.window xp ,client side written in c .

You didn't ask about a server, you asked about a client. How you accept the file on the other end is a separate question and depends what you want the server to do with the file and what web server you are using.
