I had similar thread problems with ZJetDA. I hacked around it by loading a new instance of the COM object for each thread. You can look at my code as an example. I'm sure there are much better solutions, though. http://www.zope.org/Members/jfarr/Products/ZJetDA --jfarr ----- Original Message ----- From: "Phil Harris" <phil.harris@zope.co.uk> To: "Tim Lakey" <tim@carbonwave.com>; "Chris Withers" <chrisw@nipltd.com> Cc: <zope@zope.org> Sent: Wednesday, March 07, 2001 1:29 PM Subject: Re: [Zope] Make a Zope object single threaded
Tim,
Have you called the pythoncom.CoInitialize() method before using your COM object?
This is required to use COM objects relaibly from Zope.

I am using Com Object to pull in an ActiveX control for Windows Media Encoder. I am experiencing some strange behaviours and crashes, which I believe has to do with Zope's threading model conflicting in subtle ways with Com's. So, I am thinking, that if I turn off the threading on this one object in Zope, it might solve my problem. I don't really want more than one access to the Com object happening at a time anyway, so turning the threading off shouldn't cause a loss of desireable functionality in that sense. Unless it causes problems within Zope.
I remember there being a package that can be pulled into the product to do this, but I can't find it now.
Do you have any advice?
Thanks, Tim

Out of curiosity, why do you want to? :-)
