There are many ways to do this (TCP/IP for instance), and most of them can be found with a simple Google search. CodeProject also has many articles on the subject.

Hi! It depends on how you want to send the info to your server(whether it's in XML format or some other format). If it's XML use IXMLHTTPRequestPtr::open() to connect with the server and IXMLHTTPRequestPtr::send() to send ur XML content to the server. IXMLHTTPRequestPtr::responseText; to get the response from server. Some body has already posted the whole code for this at the XML/XSL forum.

I didn't fully understand your question. You can call open() function with "POST" as first parameter and the url or IP address of ur server as second parameter. Please go through the link I've given. It contains code that can be used as such if you are working with a VC++/MFC or a Win32 project.

I would almost venture to say raw sockets over your own API is the best method for a learner... everything else, including HTML/XML/Web Services is based on the socket foundation. So understanding sockets can be a great foundation.

Either use MFC wrapper classes or Windows API (try sockets, unless you want to write a totally custom driver). Use the Linux API sets for programs that you want to run on Linux. Alternatively you could use a third party networking solution (library), but I recommend coding a front end networking class that will load up different definition files based on the values of a set of macros (ex. #define OS WINDOWS). If your object oriented skills are up to par, then it should be no problem to write it once and port it to future programs, occasionally modifying the definitions based on the API updates/changes for each respective operating system you want to support.
