echo off in VB

Anonymous · ‎03-14-2007

In lisp when "command" function is used "cmdecho" variable turns on or off
the command line "messages". In VBA, however, this variable does nothing.
I'm using SendCommand method in VBA and setting up the "cmdecho" variable
does not affect the command line "echoes" anyway. Is there any other
"variable" that can be used in VBA for similar purpose?
Thanks,

Probably because the SendCommand method is asyncrnous and will run after your vba finishes, thus, you don't see any effect. Try using ThisDrawing.SetVariable instead.

The only way not to see anything is to avoid the SendCommand function and use the object adding/modifying methods -- however, you can clean up what is written to the command line by getting rid of the prompts by setting NOMUTT to 1.

For Example:

Thisdrawing.SendCommand "line" & vbcr & "0,0,0" & vbcr & "999,999,0" & vbcr & vbcr

... will display as:

line
0,0,0
999,999,0

... just remember to turn it back on when done (kinda hard to use commands when you don't know what AutoCAD is asking).

The best thing is to only use SendCommand as a last resort only when absolutely necessary.

I've never done this before, but couldn't you set cmdecho to 0, then use SendCommand, but send it as a small lisp routine that does what you want?

The problem is not what SendCommand sends, but using SendCommand. Your vba would execute and then when its done, cmdecho would toggle on/off.

So just to clarify, if it were to be toggled off before you did anything in vba, you wouldn't have a problem?

CMDECHO has no affect on echoing of prompts
and input from SendCommand(). It doesn't matter
when you turn it off.

Well that's what i would have thought. I would relate SendCommand() to actually typing in the command manually.

Sorry, my mind was on a single track. But even if cmdecho did affect echoing of SendCommand, because SendCommand is asyncronous, it would not have solved the original problem. The OP was apparently using SendCommand do do many things, not just set a sysvar. So this could be a lesson on using SendCommand to set any sysvar.

What should happen:
Turn sysvar off
process
Turn sysvar on

What was happening:
process
vba finishes
SendCommand begins
Turn sysvar off
Turn sysvar on

Lesson: use SetVariable(), not SendCommand
