Name
IMessageFilter
Synopsis
This interface is implemented by classes that want to filter messages
before they are dispatched to your application. You should implement
the PreFilterMessage()
method, to intercept
messages, carry out any additional processing you require, and then
either pass them on to the rest of the system (by returning
false
) or cancel the dispatch by returning
true
.
To install a message filter, you can use the
Application.AddMessageFilter()
method. Note that
the installation of message filters can impede the performance of
your application, as it requires a small block of extra code and a
method call for every message dispatched.
public interface IMessageFilter { // Public Instance Methods public bool PreFilterMessage(ref Message m); }
