See Also: IMessageFilter Members
This interface allows an application to capture a message before it is dispatched to a control or form.
A class that implements the System.Windows.Forms.IMessageFilter interface can be added to the application's message pump to filter out a message or perform other operations before the message is dispatched to a form or control. To add the message filter to an application's message pump, use the Application.AddMessageFilter(IMessageFilter) method in the System.Windows.Forms.Application class.
