 ## Examples  
  The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the <xref:System.Windows.Forms.Form.InputLanguageChanged?displayProperty=nameWithType> 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 <xref:System.Windows.Forms.MessageBox.Show%2A?displayProperty=nameWithType> with <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> or appending the message to a multiline <xref:System.Windows.Forms.TextBox>.
