C#: Detecting which application has focus

Question

I\'m looking to create a C# application that changes content according to which application currently has focus. So if the user is using Firefox, my app would know that. Sam

Grrr. As is often the way, I spent some time Googling before posting this question.

Once I finally posted the question, my next Google search revealed the answer.

I've yet to test it, but it looks as though GetForegroundWindow() is the key.

Rather than me rewrite what's already written, here's a link to the page that provided the information:

Appologies for anyone's time I've wasted by asking a Googalable (?) answer.
