Luc, I assume that this 4D database is running on Windows since DDE is a Windows technology, I think DDE is Dynamic Data Entry which is a way of communicating between Windows programs, I think it was quite commonly used to send/receive information from Excel and also other applications. I think OLE technology came later possibly as replacement. Not sure how this can be done via 4D v17 - perhaps Windows experts can offer suggestions?
The solution for replacing 4D Oracle is probably to use a 4D ODBC driver (I think there is one?) on Windows and then use the native 4D SQL commands. I did something like this on Windows many, many years ago but it was to replace the 4D Sybase plugin.

They finally decided to upgrade to a more current version. I am doing a quick analysis to assets the amount of work that needs to be done. I can see the v2003 use old plugins that does not exist anymore. Most of them I can deal with but the plugins 4D for Oracle and DDE_Tools are the one that concerns me. I think M. Miyako Keisuke has developed something that duplicates the old 4D for Oracle plugins. Is it a plugin or a component ? I am not sure as I am starting to look into this. I am not too familiar with DDE_Tools. I am wondering if someone can point me in a direction to help me have more information on that plugins and how to replace it in V17. Maybe there is something similar out there now. A new plugin, a component or tech note that would help me replace it and move to v17.
