Perhaps someone can see a solution to my problem. I have put together a file maintenance section to reindex files on the PocketPC if necessary. I would like to give the user feedback with a status SAY and a progress bar. The progress bar works flawlessly, but updates to the SAY are blocked until the indexing is complete. The sample below (sorry for the length) works with the customer.dbf in the \SAMPLES directory.
Thanks in advance!
