AREV, OIENGINE.DLL (AREV Specific)

Had anyone had any experience using the OIENGINE.DLL (I think that's the name of it) that's in Open Insight, to read AREV 2.03 files?
If I convert the AREV 2.03 files to AREV 3.12, can I use OIENGINE.DLL to read AREV data into Visual Basic-based applications?

You can easily use OENGINE to read compatible (3.1+) linear hash files from within VB or similar. We covered the technique in an early SENL but using Delphi as a reference.

OpenInsight includes Xrev.dll, which an activex object which can be used from Visual basic to read and write data.

We did do this, but it was terribly slow at startup. Of course that was across a WAN over partial T1 lines. Startup times for the app where like 5 minutes. After startup it ran not great, but it was the VB Gui.
On the main network it was just slow at startup. Once started the apps ran ok to slow depending on the client.
Our biggest problem had to do with what the T1 carrier called 'line bounce' - the T1 would connect/disconnet/reconnet several times a second. This usually resulted in a broken connection to Oengine from the client and locked-up our user. They where never happy about the re-boot as it meant another terribly slow startup.
The app that is still in use, saves nearly all the "in-process" data into an Access table local on the server, and when the user chooses the "finished" or "all done" button, we transfer the data to Oengine. This seems to be the most accepted way - decouple the on-going data collection and validation from the main server, then just all the data (400+ fields) in one big blast.
We called this the ArevDataObject as it kind of looks like ADO in VB, but not really.

Pre 3.x AREV files don't work (AFAIK), but 3.x files work with OENGINE or the ActiveX control. Converting the files from 2.x structures to 3.x is a bit of a job (particularly some symbolics) and removing the "dots", but after that's done you shouldn't have any problems. VB's GUI can sometimes be a bit of an issue across slower connections (timeouts, etc.).
