This method is only called if you implemented the
IwodSFTPNotify interface in your application and the
wodSFTP.Notification
property has received a reference to an instance of your
implementation.
The StateChange notification method is called each time
wodSFTP changes its internal state. Initially it is set to
Disconnected. Once you initiate a new
connection, it will change to Connecting, etc..
Using this notification you can see if wodSFTP is doing something or it is idle and waiting for your
commands.
You can determine the current state by using State property.
