search the help for "backgroundworker"

If you want it more simple (and not multithreaded), simply add
Application.DoEvents()
somewhere in your loops.
If there are many loop runs, you shouldn't do this in EACH run of the loop, but for example only if loopcounter mod 10 = 0 (to give some time to the UI), because otherwise your loops will run much longer.
And of course, somewhere in your loop you need to check if the user canceled the job.

Don't advise people to DoEvents; get them not to perform their work on the UI thread.
