Window Not Responding when running external programs

[James Li]

I have a windows form application (C#) that launches multiple external batch
files to do various installation tasks. I want to show some status on the
win form, say simply update the text on a Lable control, "task 1
starting...", "Task 1 completed.", etc.

However, the text for the label is not being updated/showed. I understand
that the window is not responding to the Paint event anymore, How do I work
around this?

I see programs like InstallShield can do this, how did they do it?

The Paint() won't happen while the main thread is processing some other
request. One option is to handle the long task using a separate thread which
updates the label text at the appropriate times.
