Command line results to Message box

[David_Prontnicki]

Hi,

Is it possible to take the results from a command line command and place them in a message box? For example, the command, LISTAVAILABLEPOINTNUMBERS will display the results in the command line. I would like to take those results and have an alert display them.

Thank you

[I assume that's a Civil3D function, since it's not in native AutoCAD.]  Do you know whether it also puts its findings into anything like a variable, from which they could be extracted to put into an (alert) message?

[David_Prontnicki]

Yes it is a Civil 3D command, and unfortunately no I don't know if it puts its finding into a variable. I have been looking for where the command originates from to see but with no luck.

How about something simple:

(defun c:ListAvailablePointNumbers! nil
  (command "ListAvailablePointNumbers")
  (alert (substr (getvar 'LASTPROMPT) 1)) ; change 1 to 26 if you want to show the range only.
  (princ)
)

BeekeeCZ,

Simple is always better. Sometimes you overthink things. 🙂 It seems so obvious now. LOL.

Real quick so I understand whats going on:

1 - shows the range only

26 - shows nothing

Thank you so much!!!!

No. At least not to me. This is what is listed to my command-line:

Command: LISTAVAILABLEPOINTNUMBERS!
ListAvailablePointNumbers 1-4294967294

Routine then takes a part of the second line starting char number (1 or 26) to the end. So 1 is the whole second line, 26 is just a range. (word "ListAvailabelPointNumbers" has 26 chars or so) 

[David_Prontnicki]

OK got it. For me the issue is my command line displays like this:

So there is nothing at the 26th char.

Thank again!

I guess you have 'cmdecho off.

[David_Prontnicki]

Yes that's what it is. So I added get current cmdecho, set to off, and restore previous. Since I don't know what each person has it set to. That way I can just keep it set to one.

Thank you again for all your help.
