I'm beating my head against this and couldn't find anything in the archives or the MSKB (they seem to never have heard of error 3310), so I'm looking to you guys for assistance. We have an app that does nothing but watch a folder and import the files it finds there. To stress test it, we set it up with a single file (which is actually a zip file containing a series of comma delimited text files, each compatible with a table in the database structure) to import repeatedly. The import specs are there, and the thing behaves beautifully ... For a while. Then suddenly, after it has happily imported the same file several hundred times, it loses its mind and starts throwing a 3310 error, "This property is not supported for external data sources or for databases created with a previous version of Microsoft Jet" for each text file in the archive. Mind you, this is within 60 seconds of having imported the thing before. After that, NO imports are possible in the database, even from the UI until you close and restart Access. Nothing else has changed, and the database is not overly large. It isn't an unhandled error somewhere, because the module level and global variables are still populated. I can open the unzipped text files and see the data in them, but Access can no longer import it, not even from the UI. I'm not getting an Out of Memory error or anything else, but I can step through the code and see it break on DoCmd.TransferText. We're running on XP but I can replicate the behavior on Win2k and it is fairly consistent across machines with different speeds and memory, although the details of *when* it breaks vary slightly. I have a restart functionality built, shelling out to a restart app, but I want to know what's going wrong, not just paste a bandage on it. Has anyone else every encountered (and overcome) this?
