GetPage in C++?

[_charmz]

I basicly need a function that will that will grab the HTML from any webpage and place it into a string (or?) Teach me how to do it, or give me the function please. I have been looking all over the internet but nothing has helped yet .

I want to copy what GetPage from SCAR does, if you are familar with it.

Thank You

	InternetCloseHandle(hConnection);
	InternetCloseHandle(hSession);
	return retVal;

And, as you may have deduced: server is the name of the site to connect to, and path is the remote file path. A valid call would be:

string s = GetPage("www.sythe.org","/index.php");
cout << s;

   // Get the response.

   // Display the content.
   Console::WriteLine( responseFromServer );

   // Cleanup the streams and the response.
   reader->Close();

   return 0;
}
