Hi again folks,
Some of you might remember the question I asked
about 12 days ago about opening processes under
Windoze.
I made some more investigations on this topic, and
it looks like on Mac, processes can be opened (and
apps launched) by a MC standalone, and when it
quits, all apps & processes remain open.
OTOH on Win, things are different : a MC standalone
kills all processes it opened (and all apps it launched)
when quiting (or closing).
For instance, if your standalone opens a browser or
another standalone, everything will quit when your
standalone quits or is closed.
Fortunately, there's a workaround for this problem.
Actually, I needed to detect the presence of QT during
a preopenstack, then launch QTinstaller if no QT and
quit the stack. Of course, QTinstaller would quit shortly
after launching, when the calling MC app would quit.
Here's what I did : I built another (small) standalone
that just launches QTinstaller on openstack.
This new standalone is launched by the main MC app
on preopenstack.
The idea looks like this :
App1 --> App2 --> QTinstall
And the script in App1 :
on preopenstack
get QTversion()
if = 0 then launch App2
wait 500
quit
When App1 quits, it also quits App2, but NOT the
process opened by App2 (QTinstaller in that case).
Finally, when QT installation is over, App1 & App2
have quit long time ago (and in a very clean manner).
I would apreciate is anyone has comments and/or
similar experience to share on this topic...
Thanks
JB
