<p><font face="Verdana, Arial, Helvetica, sans-serif" size="2">TCPKeyBlockHook is a Low Level Keyboard Hook which can be used as a Component or Directly as a DLL from.<br>
within your Delphi Projects. TCPKeyBlockHook can hook into the keyboard driver and capture any character or system key<BR>
combination and also Block or Disable them from being processed. The Component encapsulates the procedures
and<BR>
functions
within the separate DLL and uses Memory Mapped File (MMF) to send a custom message with the keyboard<BR>
information
to the calling application or process.
You can use this Component and DLL to disable any or all Keyboard Keys. </font></p>
