RE: Remote COM Objects
> Does anybody have any experience with using Remote COM Objects? I've done a little DCOM stuff. > is there a big performance difference? It depends. Typically, when you use DCOM, you might have a centralized DCOM/MTS server, and all your web servers talk to that server. Just like with any other non-local service, there's a price to pay for network traffic, but the reward may be worth it from a management perspective. If, on the other hand, you want to have remote distributed services all over the place, DCOM will be very slow for that. That's really the big impetus for things like SOAP and Web Services - they work better over larger networks. > What happens when the remote COM object changes? Typically, when using something like MTS, whether locally or remotely, you'll end up cycling services when objects change. > and help or documentation here would be great.

RE: Remote COM Objects
Yup I have experiece but not using CF to call them but using VB instead. You have to use DCOM (distributed COM). If the COM object changes it will get recompiled and re-registered so when your app creates an instance of the object these changes will be reflected. It's been a while since I looked at DCOM but if I remeber correctly the COM object must be out of process i.e. it is a .exe (runs in it's own process space) as opposed to a dll. As far as performance goes it all depends on what the COM object does. If it throws back loads of data to your app then I guess there will be a performance hit otherwise I can't see it being an issue. -- Andrew Ewings Project Manager Thoughtbubble Ltd http://www.thoughtbubble.net -- United Kingdom http://www.thoughtbubble.co.uk/ Tel: +44 (0) 20 7387 8890 -- New Zealand http://www.thoughtbubble.co.nz/ Tel: +64 (0) 9 488 9131 -- The information in this email and in any attachments is confidential and intended solely for the attention and use of the named addressee(s).
