I’ve read on here and in other places ways to deal with this. I’m going through and removing unused table definitions. I did the same with templates. I suppose if push comes to shove, I can create 2 or more data.dlls and create application groups, and use JSON and NetTalk-based services to pass dat…

Hi again, I’m gonna get to this over the weekend. I have dozens of DLLs and 13 Frames that are defined to withj current, single dictionary. Is there a trick to defining to two and/or I think I’m in a corner when it comes to creating more browse/form/views/reports. Any thoughts or help?

The SegDef error occurs when you have a single CLW which contains too many segments. So, for example, if its a Clw with procedures you reduce the number of procedures in the CLW. For NetTalk Server apps there are a couple of potential choke points and techniques for avoiding the error. I presume t…

Bruce, Thanks so much. Well, today is the day I sit down with it. I intended to go your way with it. Also, I do watch you folks on YouTube. I just can’t do it live because of scheduling. Too many irons…Thanks again, Dave

Hey Bruce, I am going down your path. I was just surprised to see that response. Anyways this is the data.app that compiles into a dll with just the dictionary. This alone gets the error. Every DLL/EXE refers to it, including my 9 NetServers. I intend to move a field research app to the field as a …

My App Splitter is not going to help with the Data DLL and too many DCT files.

I’m assuming this is your data dll… Check the instructions for using StringTheory in a data dll. This might be relevant https://www.capesoft.com/docs/StringTheory3/StringTheory.htm#HandCoders Add the StringTheoryLinkMode and StringTheoryDllMode project defines to your project. Set StringTheory…

We have a single DCT with 1230+ tables. It is impossible to have only one data.dll without “Too Many SegDef” error.. So, we split it to two data.dll’s (it is still only one dct, everything else remains the same at it was before).. How to do that is explained in my previous post…

BobZ explanation from 2004.

Another thread on SegDef.

I have noticed Alexey always defines his variables with the Auto attribute, this may help reduce the incidence of SegDef errors. I dont know, not looked into it too much at this stage.
