now, I need your help . can you please give me some information about these functions, how to use them, & finally how can I write this program also I want to know which hooking functions should be apply to my program .
In other words, you're asking for a course of lessons on various programming aspects including Windows architecture basics, Windows native hooks and code injection, system call interception and possibly interprocess communication as well, as long as your "Word trick" thing looks much more tricky than you think of it. Do you have a faintest idea about what time that course would take? And correspondingly what money it would cost?
