hi ,

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 .

TSR is pretty out dated, it doesn't work in Windows environment. Although, this (http://www.dev-archive.com/cpp/w-p/system/misc/article.php/c5733/) isn't exactly what you need, but it will demonstrate how you can do that.
