I need to write a C++ code, where if theres a String called "hello" in the code each character should appear (character by character) on the mouse focus.

That means where ever i click my mouse (Even on an external program), and when the on focus sign appears the characters of "hello" should appear there.

I studies that theres a function in C++ called SendKeys but i am not sure if its that i should look for. Can some one tell me the keywords to google or if your'l know any example to start on, please tell me, because it would be very useful.

Help !!
