Doing print abort with a toolbar button

[CodeBrain]

I have a printing application which works quite good for some years now. It uses a modless abort dialog which can be used to abort the banded printing process. The dialog uses the well known "keep the message pump alive" method which is e.g. described in this article (http://www.codeproject.com/threads/TemplatedLengthyOperation.asp[^]. So the printing process queries an abort method of the dialog continuously which keeps the message handling alive and checks the abort button. This works very good for years now. But now I want to use a progress bar and an abort button in the toolbar of the print preview view instead of the dialog - but I am not sure if this will work with the same technique like in the abort dialog. I could not find any information about it. Everyone seems to use a dialog. Has anyone an idea if this works?

Printing in a background thread and when the UI thread tool button is clicked us PostThreadMessage to inform the printing thread of the abort.

Thanks for your answer. Of course this would work, but I try not to change how the internal printing routine work. So want to avoid using a thread if it is possible.
