Microsoft Progress bar component

[joice]

Hi:
How can Microsoft Progress bar component serve as a progress bar? From my understanding, it should be running there before everybody else is ready. When everything is loaded, it disppear. But I do not know how to achieve that.
I appreciate the help you gave me(really benefit a lot), and hope you can help me this time!

I myself When need to show some progress,will create a worker thread and place the progress function in my worker thread,it sends messages periodically to the main application thread(host of the progressbar)to update it and show the progress percent.
