[转帖]回調函數中不能使SETVAR、ENTMOD….等的原因.

龙龙仔

Haven't had any problems with setvar but any reactor
that uses 'all-documents notification or is contained in
a separate namespace vlx might not work or might
operate inconsistently with setvar, since setvar works
only with the activedocument. Instead (vla-setvariable
can target a particular variable in a particular document).
The same thing goes with getvar vs. vla-getvariable.

If all your reactors are set up locally, then the above
might not be a problem. In some cases, an elock
violation can possibly occur, although I haven't noticed
that being a big problem. That seems to be more of
a problem with (entmod)
I don't believe sendcommand is a problem but its been
so long since I have played with it, I can't be sure. I knew
that (command... will cause a problem and make the
reactor not appear to operate. Some kinds of errors
don't report to the user within reactors. In general,
any command that would require user interaction should
definitely be avoided.
