AutoCAD 2013 plugin compatibility with AutoCAD 2019

[EMD1954]

acedCommandS(RTSTR, _T("LAYER"), RTSTR, _T("T"), RTSTR, csLayer, RTSTR, NULL, RTNONE);

csLayer is a CString.  This line causes AutoCad 2019 to crash.

Any ideas?

Sorry - please disregard the "title".  It's just acedCommandS()

acedCommandS(RTSTR, _T("_LAYER"), RTSTR, _T("_Make"), RTSTR, LPCTSTR(csLayer), RTSTR, _T(""), RTNONE);

Alexander,

Thank you.  I have been doing it that way for more than 10 years and it worked in every previous version.  Without you telling me, how would I have ever found it.

Best,

Ed

Your code is completely incorrect:

1. NULL after RTSTR can produce Fatal Error

2. csLayer may have other pointer than LPCTSTR(csLayer)

3. Option _SET (e.g "T") can be used only if layer previously  created, but "_Make" create and set layer current.

Yes, now I understand.  But for the record, it worked that way in Autocad 2010, 2012, 2015 and 2017 without any problems. 

Thank you - problem solved.

Fwiw, I see from an internal bug report that this crash was noticed in 2019 and is being looked at. Probably it was just an accident that the "incorrect" code (RTSTR followed by null) worked (or at least didn't crash) prior to 2019. And then some changes to AutoCAD's command handling implementation caused the code to suddenly start crashing in 2019, as an unintended side effect.

Thank you.  I knew I wasn't crazy!
