User interface controls can only be accessed from the UI thread that created them, and attempting to update a control from another thread can result in the program becoming non-responsive or terminating abnormally. Because this event is generated in the context of the client thread, not the thread that created the class instance, you cannot directly modify a control from within this event handler. Instead, you must create a delegate and use the Invoke method to marshal invocations to the associated UI thread. For more information, refer to the documentation for the control.
