the data analyser written by JPR https://kb.4d.com/assetid=77253
had code that could essentially be used to retrieve structure information out of a data file. (but it's a compiled database) I used it to write this tool to edit the UUID of a structure and data file (was WEDD resource in v2004) for support purposes (remember catalog.xml ?) https://github.com/miyako/4d-utility-uuid-manager 2019/06/07 10:38、Jörg Knebel via 4D_Tech <4d_tech@lists.4d.com<mailto:4d_tech@lists.4d.com>>のメール: Thanks for all the input. I’m aware that I’m talking about some “hacking” a data file with a generic structure to retrieve the content. And I know about all the UUID used since v11 but I’m wondering where all the UUIDs are stored in the data file. As of now this all turned into an interesting theoretical matter to think about. ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
