OS :WinXP
LeadTools : v14.5 OCX with delphi 7
---------------

I programmed health care information chart viewer
(** image chart viewer ** ) with Leadtools v14.5, but implemeted clients not yet.

Personnel health care infomation requires security.
Some users uses print screen
and pastes into painter , saves images into USB or etc.

Is there any property or methods to protect copy images ?

We
do not have a specific function in LEADTOOLS to override the 'Print Screen'
key. This is a global key that works Windows-wide, and not specific to our viewers.

You may find such a function or event in the Windows API documentation, but I'm afraid I don't know where exactly.
