One of the features of our main app is the ability to convert data from competitors' DBs into our DB, which actually happens pretty frequently. That is done by having the client's files from the competitor's SW on the same computer that we install the current PB app onto, and usually using ODBC drivers for their database type to read their data and save it into our DB, using DataStores for the transferring.

I'm wondering how that would work in an Appeon Web version of the application, since as I understand it all DataWindow data-access work is then done on the server, not on the client. So could it read data from local files on the client?

Would part of the solution be uploading the files to the Appeon server? But can our code then even access such files? And since the DBs involved (DBase, Access, and DBISAM) aren't ones that are claimed to be supported by Appeon, would it even be able to access them, even if we were running Appeon on a Windows server and had those ODBC drivers installed?

Or is there some completely different approach we should be thinking about? I don't want to have to remove this feature. (Of course, we could offer to do it locally for a price, but honestly that's an administrative task I'd rather our small business didn't have to be involved with, given that currently the users can do it themselves!)

Thanks.
