same thing in command line twice?

[Anonymous]

hi,
i load vba routine thru lsp file which is loaded at startup.the syntax is

(defun c:ndoor ()
(command "-vbarun" "ndoor.dvb!ThisDrawing.ndoor"))

when i type ndoor in command line same thing is asked twice.in first line nil is written.

Command: nd -vbarun
Macro name: ndoor.dvb!ThisDrawing.ndoor
Select inner edge of wall: nil
Select inner edge of wall:

when i run this thru vb editor,it works fine.what is the problem?
thanx

I think the solution is to add a vbcr before your prompt, like:

ThisDrawing.Utility.GetEntity obj, points, vbCr & "Select MultiLeader: "

thanx allen,
problem still remains.i have many vba work and same problem comes to all. only first line is asked twice.and first has nil.may b thr is problem in vbarun syntax?

Bhuta, problem is I think in Lisp and not VBA, a Lisp will print the final statement twice, once as you intended and the second time as the output of the program.

Finish your Lisp routine with a (princ) command and this should stop, i.e.

(defun c:ndoor ()
(command "-vbarun" "ndoor.dvb!ThisDrawing.ndoor"))
(princ)
)
