XMPP Component [IP*Works! V8]

Properties Methods Events Configuration Settings

The XMPP component is used to create a lightweight messaging client using the XMPP (Jabber) protocol.

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

A call to the Connect method will perform the entire logon process after which a Connected event will fire indicating connection status. For simplicity, the entire interface is synchronous: the component will not return until a call is completed.

After a successful connection, the component will automatically begin the process of receiving the user's buddy list. The component will parse the XML as it comes in from the server and will set the appropriate properties. Once the entire buddy list has been retrieved, a Sync event will fire.

Sending a message is as simple as calling a single method. One call to the SendMessage method will cause the component to connect if it has not already done so, send the specified message to a specified user, and return to the original connection state.

The XMPP component interface supports messaging, list and presence management. Other features of the XMPP protocol are supported through the SendCommand method and PITrail event.

Example (Connecting and Sending a Message)

IMControl.Connect("myusername", "mypassword") IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser")
Example (Sending a Single Message)

IMControl.User = "myusername" IMControl.Password = "mypassword" IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser")
