Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Occurs when the application finishes processing and is about to enter the idle state.
public:
static event EventHandler ^ Idle;public static event EventHandler Idle;public static event EventHandler? Idle;member this.Idle : EventHandler Public Shared Custom Event Idle As EventHandler Event Type
Examples
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the Idle 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 Form and make sure that the event handler is associated with the Idle event.
private void Application_Idle(Object sender, EventArgs e) {
MessageBox.Show("You are in the Application.Idle event.");
}
Private Sub Application_Idle(ByVal sender As Object, ByVal e As EventArgs)
MessageBox.Show("You are in the Application.Idle event.")
End Sub
Remarks
If you have tasks that you must perform before the thread becomes idle, attach them to this event.
Caution
Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result.
