Subject: how to connect to xmpp server

hello experts,

i want to build an application that will connect to xmpp server and allow users to do voice and text chat...
my first tasks is straight forward... i am using dotnet... how can i connect to xmpp.. i have installed openfire on my local network..192.168.0.58, i guess it works on 5222 port....

 protected void Page_Load(object sender, EventArgs e)
        {
            string uri = "http://chd-wrkstn-043:5222";
            string fileName = Server.MapPath("test.xml"); 
            WebRequest req = WebRequest.Create(uri);
            req.Method = "POST";
            
            req.ContentType = "text/xml";
            //req.ContentLength = 790;
            StreamWriter strw = new StreamWriter(req.GetRequestStream());
            strw.Write(GetTextFromXMLFile(fileName));
            strw.Close();
            WebResponse resp = req.GetResponse();
            StreamReader sr = new StreamReader(resp.GetResponseStream());
 
            string a = sr.ReadToEnd().ToString();
            sr.Close();
            string str = resp.Headers.ToString();
            string ssd = resp.ResponseUri.ToString();
        }
 
        private string GetTextFromXMLFile(string file)
        {
            StreamReader reader = new StreamReader(file); 
            string ret = reader.ReadToEnd(); 
            reader.Close(); 
            return ret; 
        }

XML file

<iq to='chd-wrkstn-043'
type='set'
id='sess_1'>
<session xmlns='urn:ietf:params:xml:ns:xmpp-session'/>

Hello Alex,

I did download one agsxmpp... but couldnt get any help... the documentation lists a bundle of classes which are quite confusing... the sample has sytax for making connection... so how would i send message to the other user... and also wht abt voice chat... what classes are used to handle these tasks..
thats why i started with creating my own....
i guess we only need to post the xml on openfire... and it shd do the rest... so whts the way to connect to openfire... without any of the above library

please study the MiniClient example. There is all you need.

this is not included. You have to extend agsXMPP for the XMPP Jingle protocols.

As I said before, please use one of our libraries MatriX or agsXMPP for connecting to your Openfire server. Or any other library you prefer. Connecting to a XMPP sever is a complex task and much more than only sending a small XML snippets.

If you still want to wrote your own code then please study the RFCs which I mentioned in my previous post.
