Trapping Exit of AutoCAD

Anonymous — Sun, 16 Apr 2000 21:24:33 GMT

In r12 selecting Exit AutoCAD under the File menu actually invoked the Quit command. By redefining this command I was able to prompt the user to make sure the drawing was saved when certain conditions were detected.

In A2k selecting Exit under the File menu doesn't seem to call the Quit command. My redefinition won't work. Is there a way to trap an attempt to exit AutoCAD and display my custom dialog as I was able to do with r12?

I discovered a slick workaround for this problem!

Look at the line for Exit in the ACAD.mns file:
ID_APP_EXIT [E&xit]

If you look at the ***HELPSTRINGS section, there is _no_ ID_APP_EXIT listed.
I found that if you change that helpstring on that line to something else,
e.g. ID_My_Exit, you can undefine Exit & roll your own! This also works for
the Close menu item.

This doesn't really solve the problem. There are a
few other ways to terminate AutoCAD which don't use
any commands (e.g., clicking the X in the caption
bar for example).

Unfortunately, command redefinition is not the
solution here.

Yes, it only solves the pull-down menu pick. I thought I had tested it, the
first time I discovered this feature, with the X button, but I guess not.
:-(

Oh, come on, Tony, wasn't it cool?! Who would have thought changing the help
string would change the behavior of those two menu selections?

Robert;

It's good to know that. Maybe dcleghorn will benefit
directly. For fun, did you notice whether you can re-define
File/New also? (I've done very little menu customization.)
For myself, I'm trying reactors for my current task.
The :vlr-beginClose reactor seems to trap all these variations
of the close event:

1. if SDI=0, File/Close (the drawing containing the reactor)
File/Exit
Window "exit" button

2. if SDI=1, File/Close
File/Exit
File/New
Window "exit" button

File/New is easy. No jumping thru hoops (or menu edits) required. Just
Undefine New, then create your own (defun C:New () . . .)

One of these days, I'm going to have to start some serious development on
reactors. Wish I had only 1,000 things to do, instead of millions! Maybe if
I change my title from "Net Admin" to "At Home, Don't Bother Me,
Programmer"? . . .

I don't think it has anything to do with the helpstring or the
command named "EXIT" (that command is not issued when you pick
File|Exit).

It's the menu item identifier "ID_APP_EXIT" that associates
the action with the menu item. This action, along with a
number of others on the file menu, are "hard-wired", so by
changing "ID_APP_EXIT", you're changing the hard-wired macro
that's associated with the File|Exit menu item, that's all.

My advice is to avoid command redefinition. You're taking
the right approach with reactors.

If only reactors weren't such a PITA with VLisp... 😞
