Summary
Wrapper component for the RegisterShellHookWindow and DeregisterShellHookWindow Windows API functions.
Pascal
run\JvShellHook.pas
TJvShellHook = class(TJvComponent);
Description
- JVCLInfo
Wraps calls to RegisterShellHookWindow and DeregisterShellHookWindow into a simple to use component. RegisterShellHookWindow registers a specified shell window to receive certain messages for events or notifications that can be useful to shell applications. The event messages received are only those sent to the shell window associated with the specified window's desktop. Many of the messages are the same as those that can be received after calling the SetWindowsHookEx function and specifying WH_SHELL for the hook type. The difference with RegisterShellHookWindow is that the messages are received through the specified window's WindowProc and not through a call back procedure. See MSDN (http://msdn.microsoft.com, search for "RegisterShellHookWindow") for more details

Notes
The RegisterShellHookWindow and DeregisterShellHookWindow API functions may not be available on all versions of Windows. To detect if the API is available, set Active to true. If it remains true, the API is available. If it is reset to false, the API is not available.
