You can't.
The Tick event happens asynchronously, but occurs on the same thread as the original code - so if your code starts a timer and then does a long running operation while loading you still won't see anything. The only way to get round that is to move the long running operation to a second thread (see the BackgroundWorker class[^] and report progress to the main thread to update the display.

And your code won't work, because your Nonameclass creates a new instance of the Form1 class which is never displayed. To display anything you would need to access the actual instance that created the Nonameclass instance and that means passing the Form1 instance to the constructor. Which is a bad idea, because it breaks OOPs and locks the two class designs together, as does exposing the TextBox publicly in your Form1 class!

You need to think about exactly what you are trying to achieve here, because the route you are trying to go is a bad idea. What you really want to do is probably possible, and even quite easy - but this way is not a good route to that (or anything else!)
