Folks:

Has anyone had success connecting to a Progress-4GL database with Delphi? 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!
