Insert text into Wordpad

You want to write C# code that inserts text into an open instance of wordpad ? Judging from the subject you chose for your post, I'd say that this is completely beyond you. You should buy a basic 'for dummies' C# book and work through it, then move on when you have some basic programing skills. Even then, the task, if I get it right, can only be done via hacks that are not reliable, or recommended. Why would you want to do such a thing ?

As baconbutty said, you'll need to use the methods within the user32 library. But, I would also guess that this is a bit advanced for you, though a little help in google can do it.

You'd have to first find the handle for the window, then use SendKeys to send the text to it. It can be done, but you'll have to do some research (google). Since I don't know straight off the top of my head how to do that, and since doing the research won't help me in anyway, it's up to you to do it.
