Remarks

Triggers the WinApplication.CustomHandleException event. If the event’s Handled parameter is not set to true , the message box is displayed via the Messaging.Show method (an overload that takes the caption and exception parameters is used).

The HandleException method is called each time an exception occurs when running a Windows Forms application (see the snippet from the Program.Main method below).

• C#

static void Main() {
    // ...
   try {
        winApplication.Setup();
        winApplication.Start();
    }
    catch (Exception e) {
        winApplication.HandleException(e);
    }
}
