title: manipulating the simple windows Calculator using win32 API in c#?
body: <p>Well, I've tried my best to look at code examples and posts all over the web on how to do this, but I haven't been able to make any headway in a few months using windows API to interact with another program that's already running. I'm not the greatest programmer and some of this stuff is beyond me. </p>
  
  <p>The most I've been able to do is find the Calculator process and its handle, and use that with SetWindowText to change the title. What I'd really like to learn how to do is make my program use the windows user32 (I think this must be the correct library) to enter some numbers by actually pressing the number key buttons on the software calculator to do a simple calculation.</p>
  
  <p>I don't really have a use for this program, it's just a goal I'm trying to reach to learn how to use the windows API past my very beginner level SPECIFICALLY in C#. If no one has the code for this, or even if you do, I'd most appreciate some suggestions for books or resources on the web I should be reading to learn how to do this.</p>
