how do windows applications work?

[ilovegold69]

i am trying to make a simple application that just types a random number in a search engine. i can do everything except for making the program do things on the screen. i tried making a windows application with visual c++ but its like learning a new language. can someone tell me how i can make a program just type something in for me?
