On click of a button I have this code with is should show a dialog on top of the current form and display text, wait for one second, change the text and then finally close it:

Form p = new Form();
p.ShowDialog();

p.Text = "Start.";
Thread.Sleep(1000);

p.Text = "Counting.";
Thread.Sleep(1000);

p.Text = "End.";
Thread.Sleep(1000);

p.Close();

However once it executes p.ShowDialog(); it stops the code until the form p is closed and it doesn’t work as I intended it to. Can I get some guidance on this? Not necessarily the solution, but at least maybe some keywords I could google on?

UPDATE: due to the difficulties I am facing trying to access business logic, which is irrelevant to the problem, I am delaying providing the working example. Stay tuned and sorry 🙂

SOLUTION: what I did is in fact used Show() instead of ShowDialog(). Since i was impossible to access form from business logic, BackgroundWorker came in handy and was being used between them. I cannot share any code or the layout of the project structure, but in conclusion, the accepted answer’s main statement was the key to the solution 🙂

    That is the point of ShowDialog(). It creates a modal form and does not return control to the calling function until you are done. If it doesn’t need to be modal, then use .Show(). If it does need to be modal, then put code in the Form Load method to update the text as needed.
