If you could adjust your code so that you set a flag once a process has begun and then check that in the UI before you start an additional operation I think you'd have a much easier time coding this. I would create a delegate that could be called from the thread in the threadpool or user created thread to update on progress in the UI. Once the background process has been completed switch the flag and now normal UI operations can continue. The only caveat you need to be aware of is that when you update UI components you must do it on the thread they were created on, the main/UI thread. In order to accomplish this you can call the Invoke() method on any control that lives on that thread and pass it the delegate and parameters you need to call it.

Here's a link to a tutorial I wrote some time ago about how to use Control.Invoke():
