Examples

The following code example demonstrates using this event to determine whenever a notification is created. This code example is part of a larger example provided for the Notification class.

' You can use the BalloonChanged event
' created by tracking each time the notification is made visible.
Private Sub OnBalloonChanged(obj As Object, _
  balevent As BalloonChangedEventArgs) Handles Notification1.BalloonChanged
   If balevent.Visible = True Then
    ' You can add code here to add 
    ' functionality such as user interface 
    ' changes that should occur when
    ' the notification is displayed.
   End If
End Sub

// You can use the BalloonChanged event
// created by tracking each time the notification is made visible.
private void OnBalloonChanged(object obj, BalloonChangedEventArgs balevent)
{
    if (balevent.Visible == true)
    {
        // You can add code here to add 
        // functionality such as user interface 
        // changes that should occur when
        // the notification is displayed.
