[wxPython-users] Distributing a wxpy app - central server or each workstation

[Geoff Skerrett]

Thanks for your response we have tried the network share and everything
works fine.  We have designed our app to ensure that that the "work"
files are unique to the user, so we aren't to worried about those types
of collisions. 
 
 I guess my questions is more related to .dll's and perhaps it is more
about dll's in general than specifically wxpython.  By way of
explanation, I am a newbie to development and I have this vague
recollection from a conversation several years ago where someone
mentioned that .dll's in a Windows environment can't be shared between
applications ... might honestly have been from Win95 days and might even
have been related to .vbx files, not .dll's at all. 
 
So let me apologize my vague question earlier and I will try and be more
precise.   I understand that the practice is to install the .dll on the
workstation, however, are there any "technical" barriers to have 50
instances of the client application using a single set of .dlls loaded
on a network share.  -- ie, do .dll's have some sort of locking
mechanism that prevents "sharing" or once the app loads the .dll and
accesses it's functions/objects is app's instance of the .dll unqiue to
that app ?

Hi

Well, that should be farly easy to test. Just put your app on one
computer and share the directory. Mount that as a network share on a
different machine and fire it up. There could be all kind of problems if
your single install can't handle multiple clients though. Like all
instanses share the same directory to store data and stuff like that.
But I have at least been able to run an installer written in wxpython
from a network share so there's nothing that stops you from doing this
if the app is designed "correctly". All the dll's is in the same dir as
the app so windows will be able to load the dll's.

	We are distributing a wxpython application using py2exe.  We
have a new client with approx 50 workstation and were wondering if need
to install the supporting .dll's on each workstation or could we install
these on network share and then have a short cut on workstation desktop
that points to the .exe on the network share.
	 
	Thanks for any assistance on this.
