// Creates a message filter. [SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.UnmanagedCode)] public class TestMessageFilter : IMessageFilter { public bool PreFilterMessage(ref Message m) { // Blocks all the messages relating to the left mouse button. if (m.Msg >= 513 && m.Msg <= 515) { Console.WriteLine("Processing the messages : " + m.Msg); return true; } return false; } }
