I'm looking for a line of code in Delphi which can disable sending keys to an application. For example I have a game.exe, I want to disable sending keys to it, so you can not play it.
How to do that? Please Guide me step by step :)

I still don't understand. At the moment, in order to answer this, we have to guess what you mean. Please spend more time editing the question to explain exactly what you want, preferably with some examples to make it 100% clear.David Heffernan– David Heffernan2011-08-04 12:42:36 +00:00Commented Aug 4, 2011 at 12:42

Hiding and blocking input should be separate questions. Your question is so vague that I'm tempted to vote to close it, but here are some general ideas instead;
If you want to block all input from getting to an application,you can simply grab the focus away from that particular application, or keep your window on top and make it full screen. This is often called "Kiosk mode".
You could also forcibly hide all the application's windows.
You could intercept the window messages that are bound for that application and handle them yourself. See the link from Johan on Keyboard hooking.
