Question about modal forms and flows

Question

In the main thread, I need to do the following:

• Create a second thread where I show a modal form that will act as an “activity indicator”
• Run the task (this task MUST be executed from the main thread)
• Close the form created in the second stream.

The question is that I don’t know how to show the modal form and not stop the main thread.

Any suggestion?

Answer 1

I would use ThreadPool thead ... something like ...

ThreadPool.QueueUserWorkItem(o => dlg.Show());

This will launch the dialog in a separate thread. Your main thread will continue processing.
