More info about acedCommand

[Anonymous]

I am working on the legacy code, I came across the following code

acedCommandS(RTPOINT, pt, 0);

any idea about what it does?  I looked for the definition of RTPOINT and it is as below in the file adscodes.h

#define RTPOINT   5002 /* 2D point X and Y only */

My legacy code is not working properly because this piece of code is not working properly and I am not able to find anything about the same. Thanks in advance.

You have to call acedCommandS with full command. Such as: acedCommandS(RTSTR, L"_POINT", RT3DPOINT, pt, 0);

But you can not call acedCommandS with not full command data.

In any case, I recommend not using acedCommandS/acedCommandC and replace it with own code.

Thank you Alex for reply, I found this in my legacy code which was working in the prior versions, it was acedCommand instead of acedCommandS.

if we go with acedCommandS(RTSTR, L"_POINT", RT3DPOINT, pt, 0); it will create a point entity. but this code was not meant for creating point. Any idea or observation where it is used in the form I mentioned? Thanks a lot in advance.

It can was used in loop of providing vertexes of Polyline such as:

acedCommand(RTSTR,L"_PLINE", 0);

for (int i = 0 ; i < n; i++)
{
  acedCommand(RTPOINT,pts[i],0);
}

acedCommand(RTSTR,L"",0);

But with acedCommandS you can not do the same as far as acedCommandS have to be have full command list from start to end. For example,

acedCommand(RTSTR, L"_PLINE", RTPOINT, pts[0], RTPOINT, pts[1],  RTPOINT, pts[2], RTSTR, L"", 0);

Thank you so much Alex, this is something I was not really aware, acedCommand(RTPOINT...). Now we can't replace this with acedCommandS() as it accepts only full parameters. So as you said it was getting used for setting the vertex of a polyline. How we can replace in ObjectARX 2017? Any clues? Thanks in advance.

In order to try help you I have to see your code.

Hello Alex,

I am able to move ahead with the input you gave, thanks a ton for the same! Command could be ended in the earlier versions of ARX by using acedcommand(0). So if I call acedCommandS() for line or polyline command, is there any way I can do it like acedCommand(0)? Will appreciate your input.

Thanks in advance.

You try to do impossible things. Please look at this sample (it is using acedCmdS instead of acedCommandS):
