Controlling the Display
The icons and folders on your desktop are rendered and maintained in a ListView control that Explorer creates. When IconLock.exe starts up, it loads LockIcon.dll, which installs a thread hook to wait for a message from Explorer. When a message is received, LockIcon.dll subclasses the Explorer controls SHELLDLL_DefView and ListView so that it can process the required messages. This technique of injecting a DLL into another application's process space is well documented in Jeff Richter's book Advanced Windows (Microsoft Press, ISBN 1-55615-677-4).
