We've got a BIG application server (50 remote datamodules, LOTS of methods per datamodule) that was developed using BCB3 C/S. We desperately need to upgrade to BCB4 Enterprise (or maybe 5, but I haven't heard many good things), but how should I go about migrating all of the code? I've actually gotten the v3 code to compile using BCB4 (I had to make some minor syntax changes for some things -- most of those were noted in the docs), but it won't run. When my client app (also rebuilt under 4) makes its first Midas connection call, I get some sort of COM/DCOM error. I've create identical apps from scratch using both 3 and 4 -- then compared the code. There are definitely some differences. Could these differences (in the auto-generated code) be the reason why my v3 app compiled under v4 won't run? What are my options? It would take FOREVER to start with an empty app and re-create this app server from scratch (even if I did cut/paste the code from the methods in the old code). Has anyone been down this road before? I posted about this a year ago, and never got any response (other than "try posting in the xxxx newsgroup"). I'm attending BorCon in a couple of weeks -- I hope to be able to corner some gurus during it and get some answers on this. Any help would be GREATLY appreciated!!!! Thanks in advance, Kevin Talley (ktalley@edge.net)
