text capture

I'm looking to capturing and processing text that is spit out of a textbox of an application running in windows. How would I go about being able to "spy" and hopefully steal the text coming out of a particular program in my own .net program?Please ask all Windows Forms questions on the dedicatedWindows Forms Forums.
Are you talking about using asp.net, or a windows application?

One thing you could do is have a key capturing program installed on your computer, that inserts every "Key stroke" into a text file. Then you could have you asp.net application read from that text file. Depending on what you want to do, you might even be able to build some pretty nifty functions out of asp.net.
