Porting a large Object ARX C++ application from AutoCAD Map 2015 to 2020

[JohnGaeta1192]

Hi our organisation has a large Object ARX C++ application which we are porting to from AutoCAD Map 2015 to 2020

The application has an Oracle and ESRI SDE interface, it has similar functionality to Automated Utility Design (AUD from SBS) which is what we are eventually moving to but in the meantime the app requires upgrading.

I'm using VS2019 compiling as 2017, I have managed to compile the ARX and it loads into AutoCAD Map via the debugger.

Question 1/ what changes should I look out for when porting from 2015 to 2020 that may cause me issues along the way.

Question 2/ When the arx is loading via the debugger I get  "acad.exe has triggered a breakpoint." Is this something that is an issue or can be ignored? How do I get further information when source is not available?

Cheers

John

Re question 2/ I started AutoCAD Map with the debugger but without loading the ARX automatically and still received  the error message "acad.exe has triggered a breakpoint." so the arx is not triggering this issue... would still be good to know what is triggering this

I was able to load it manually within AutoCAD without error.
