Error 1 error C3861: 'MustSwitchTo_acedCmdC_or_acedCmdS': identifier not found

[DWhiteley]

Hi,

I'm programming with C++ (VS 2012) using ObjectARX 2016

I have a line:-      if (ads_cmd(rbCommandList) != RTNORM) {......

The ads_cmd gives the following error:

Error 1 error C3861: 'MustSwitchTo_acedCmdC_or_acedCmdS': identifier not found 

I see that this is defined in adsmigr.h as:-

#define ads_cmd MustSwitchTo_acedCmdC_or_acedCmdS

How do I correct this error?

Many thanks in advance,

Dave

ads_cmd() is defined in adsmigr.h.

Until ARX2014 it was defined as acedCmd().

Starting with ARX2015 AutoCAD switched over to "fiberless operation".

Due to this breaking change acedCmd() must be replaced bei either acedCmdS() or acedCmdC().

The same change applies for ads_command() / acedCommand().

Please read the docs about "fiberless operation".

I would recomment to avoid acedCmd*() / acedCmd*() whereever possible.

If you are lucky you can use the "S-type" functions. The usage of the "C-type" functions is horrible.

Many thanks for your help.

Hello,

I have had the same problem, and with the help of the arx's migration guide, I could see that I have to change acedCmd for (acedCmdS/acedCmdC).

I have began changing them for acedCmdS, but I am having an error with the command "Break" when I want to break a line. This is my code:

ads_name NameSegment;

VOK(acdbGetAdsName(NameSegment, GetObjectID()));

ads_point PointBreakNode={BreakPoint.x, BreakPoint.y, 0};

//create break command

struct resbuf* pCommand = acutBuildList(

RTSTR, L"_.BREAK",

RTENAME, NameSegment,

RTPOINT,PointBreakNode,

RTNONE);

ALLOW_NEXT_COMMAND;

//int nResult=acedCmd(pCommand); //My old code

int nResult = acedCmdS(pCommand);//My new code

The message error is the following:

"Exception thrown at 0x000007FED35F1157 (accore.dll) in acad.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.

If there is a handler for this exception, the program may be safely continued."

If anyone have experimented a similar situation and could give me any clue to solve it, I will be thankful.
