How to paste text into a different application with C#

Here is my scenario: A user has two applications open. Let's say one application is Notepad with some text in it and the other one is my C# application.

A user now positions the mouse cursor somewhere inside the Notepad text and then clicks a button in my C# application. As a result, a text string from my application gets pasted in Notepad where the cursor was positioned.

My question is: what would a general approach be to accomplish the above, and possibly what classes etc. are recommended?

I would look into using interop calls to accomplish this. Look at specifically GetWindow() and SendMessage with the WM commands (http://msdn.microsoft.com/en-us/library/windows/desktop/ms644927(v=vs.85).aspx#system_defined) and GetDesktop().

GetDesktop will allow you to obtain all of the top level child windows of the desktop (all top level windows are children of the Desktop window).

You should then be able to use GetWindow to obtain the window handle you are looking for and then SendMessage to set the text into the textbox.
