hi ,
How are you? I am using a software for my business.I want a tsr program which can help me stop using of some buttons from the keyboard.Like cntrl+delete combination key, f6 function key and some others. And in the same way i want a program to deactivate the above program to make the keyboard keys function normally. I am using windows xp .Please help me .

and it would not be a TSR. That name is specific to a category of DOS programs that would load and stay in the background.

some keys cannot be hooked by the way (they are reserved for the OS e.g control+alt+del)
