Subject: Can't connect to server (ASP.NET)
Hello,

I try connect to my server from my ASP.NET application. But I can't do it.

When I trying connect to my server from MiniClient it will be connected successfully.

Its my code:

void btnConnect_Click (object o, EventArgs e) {

    agsXMPP.XmppClientConnection xmpp;

    xmpp = (agsXMPP.XmppClientConnection)Application["xmpp"];
    if (xmpp == null)
    {
        xmpp = new agsXMPP.XmppClientConnection();
        Application["xmpp"] = xmpp;               
    }

    xmpp.OnLogin += new agsXMPP.ObjectHandler(xmpp_OnLogin);
    xmpp.OnReadXml += new agsXMPP.XmlHandler(xmpp_OnReadXml);
             xmpp.AutoPresence = true;
   
    xmpp.AutoResolveConnectServer   = true;

    xmpp.Port                       = 5222;          
    xmpp.UseSSL                     = false;
    xmpp.Server                     = "myserver.com";
    xmpp.Username                   = "login";
    xmpp.Password                   = "pass";
   
    xmpp.Open();
}


private void xmpp_OnLogin (object sender) {
    litConState.Text = "logged in";
}

private void xmpp_OnReadXml (object sender, string xml) {
    txtServerResult.Text += xml + "\r\n";
}

Event OnLogin not firing. I don't understand why

did you look at the basic webclient example which ships with the SDK?
Does it work for you?

If not please post your Xml log.

I try to add OnWriteXml and OnReadXml events, but it's not firing. When I click on button (btnConnect) I have page postback and nothing else. I don't recieve any error. Can I debug connecting process other way?

add the source or a debug version of agsXMPP to your code and start debugging with the Xmpp.Open call.

Sorry, Alex, but I don't use VS2008. I have only VS2005. Do you have WebClient example for VS2005?

no, there is no VS2005 version. Yuu can create a empty project and add the sources.

Finally I found where is my error. This error is not an error in SDK. In xmpp_OnLoad event I try to set value in litConState.Text, but in this function it's not working (I think because this event called in another thread). In MiniClient example I saw instructions:

    if (InvokeRequired)
            {
                // Windows Forms are not Thread Safe, we need to invoke this :(
                // We're not in the UI thread, so we need to call BeginInvoke               
                BeginInvoke(new ObjectHandler(XmppCon_OnLogin), new object[] { sender});
                return;
            }

Can I use something like this in my ASP.NET page to marshal the call to the proper thread?

I am also experiencing this problem, you are now resolved? Server-side events to trigger the client can not be changed, and the winfrom Yes, I would also like to know why

Please read other threads about this topic.
agsXMPP is running on the webserver. And by default HTTP is not a bidirectional protocol. So the webserver cannot raise events on the browser.

But there are techniques like Comet which make this possible. So you have to use them and combine them with agsXMPP. Or you have to use Silverlight and MatriX. Silverlight is running on the Browser and it much easier for you.
