What do you mean by exchange text box control

Seriously. Read a book. Make some effort to learn something before you start asking questions.

I did a search on MSDN and Google and couldn't find one entry for the " exchange text box control"... must be something new coming in VS.Net 2014?

I think it's more likely a "lost in translation" language problem.
