Application.EnterThreadModal Event (System.Windows.Forms)

.NET Framework Class Library

Application..::.EnterThreadModal Event

Occurs when the application is about to enter a modal state.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

Public Shared Event EnterThreadModal As EventHandler

public static event EventHandler EnterThreadModal

public:
static  event EventHandler^ EnterThreadModal {
	void add (EventHandler^ value);
	void remove (EventHandler^ value);
}

member EnterThreadModal : IEvent<EventHandler,
    EventArgs>

Remarks

Caution
Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result.

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the EnterThreadModal event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox..::.Show with Console..::.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a Windows Forms and ensure that the event handler is associated with the EnterThreadModal event.


Private Sub Application_EnterThreadModal(ByVal sender As Object, ByVal e As EventArgs) 


    MessageBox.Show("You are in the Application.EnterThreadModal event.")

End Sub


private void Application_EnterThreadModal(Object sender, EventArgs e) {

   MessageBox.Show("You are in the Application.EnterThreadModal event.");

}
