Application.RemoveMessageFilter Method (IMessageFilter)
Removes a message filter from the message pump of the application.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You can remove a message filter when you no longer want to capture Windows messages before they are dispatched.
Before you can use a message filter, you must provide an implementation for the IMessageFilter interface. The following class creates a message filter called TestMessageFilter. This filter blocks all messages relating to the left mouse button.
