    1. Why do you think you need to "read the contents of the edit box when the thread is getting executed"? How often do you need to do it?

    2. I already gave you a link to a very useful essay about using worker threads here. Have you read it (the essay)?

    Windows is a message-oriented operating system, so you don't need a separate thread for doing that. Whenever a button is pressed, a message will be sent that you can handle. Preferably with message maps if you're using MFC.

    Indeed you can read the content using the edit box member variable. But you have to do it in your main GUI, not from within a worker one!

    As said in one of your other threads, do not access the UI from worker threads, only from the main thread.
