Delphi连接到OpenEdge Progress-4GL数据库

Question

Folks:

Has anyone had success connecting to a database with ? I've been unable to establish any connection with the ODBC driver provided by the vendor ( Progress OpenEdge 10.1C Driver ). I've entered (what I believe are) the right parameters, but keep on getting an error whenever I test the connection:

   "[DataDirect][ODBC Progress OpenEdge Wire Protocol driver] Socket closed."  

Background: I've been tasked to re-design a 13-year-old application, but the original programmer did not provide any supporting documents, passwords, configuration setup, etc. (I'm on my own)! To make things worse, online help and useful documentation about Progress is scarce (I had never heard about this database until now).

I want to examine the existing data, maybe create an ERD to familiarize myself with the schema, but I can't even access the data outside of the OpenEdge code.

Any help is appreciated!

Answer 1

If you need help with Progress I suggest you enlist in one or more of the Progress mailing lists at PEG .

Progress is a niche product, and didn't age well, or at least the technical decision taken (and defended) by Progress were abandoned by the rest of the industry, so some things you may take for granted will prove cumbersome or at least a bit alien.

Anyway, PEG is a great resource and the people in there are very knowledgeable and usually eager to help people working with Progress technology (or so they were when I used to subscribe, a few years ago).

I've seen that databasen when I was on college. We had some excerises with it and as far as I remember it was awful experience.

Maybe this link will help. I whish I could help more, though.
