ThreadProc ( ) : void	the main update thread for the data. Since the information is coming from a web service which might take a while to respond, it is not logical to let the application hang while waiting for response. Therefore, running the request on a different thread frees the application to continue working while waiting for a response. Please note that in this case, synchronization of shared resources must be addressed, otherwise you might end up getting unexpected results.
