Notification in thread

Question

Hi,

I use a notification balloon in my application to alert users about a specific event.When the BalloonChangedEvent is fired, I dispose the notification.

When I call notification from the UI (e.g. a button click), the balloon is disposed correctly but when I call it from a background thread, the event never fires up.

Thanks,

Answer 1

1. Raise and event in your background thread. 
2. Add a handler for that event to your UI code.
3. Inside the event code handler, Invoke a Delegate method to change the state of the UI.  You cannot change the UI directly from the event, you must Invoke a Delegate to allow the STAThread process to execute the change.

Hi,

Thank you for your answer.

I finally used Action class to show the nofitication

Invoke(new Action(() => ShowMessage()));

and it worked perfect.
