2) I have a lengthy procedure running and I am trying to use a

the window with the bar does not draw it self. The program is
busy with the procedure and the window is at an "Not Responding"
state. After that I can see the bar full and the procedure to end
Do I have to put it in a thread? But I don't want the user to do
other things. He has to wait to finish. I have tried it with a
timer but the same thing happens.
You should put the procedure in a thread and somehow prevent the
user from proceeding while the procedure is running.
I accomplish this by placing my progress indicators onto a sheet
window. I then use "ShowWithin" to display it, start the thread
(which updates the progressbar), and then Close that sheet window
when the thread is done.
That performs 2 functions - it keeps unnecessary clutter off of the
main interface (the progressbar) and prevents the user from doing
anything until I close the sheet window when the thread completes.
Or in a moveable modal dialog (this way, the entire application is
locked. Also, I find more ugly a sheet window with only a progress
bar (and an optional cancel button) than a modal dialog with only a
progress bar)).
