Isn't a web service just an asp.net app w/out the html user-interface goo? My guess would be you'll have all the same problems.
I guess a winforms app is out of the question on this? I bet it'd be way more efficient not to be moving all those bits to/from a server... -Roy -----Original Message----- From: Discussion of advanced .NET topics.

Thank you Peter for the reply and information. I always had the impression that even if I did use the GC.Collect() that even then it doesn't garuntee that the GC will fire then and free the disposed objects. Am I correct on this? I believe I read in one of the refered links that the File objects arent recognized by the GC and would be a good reason to use the Collect on it. I might try this and see what happens. What about the WebService route? I know I didn't really go into detail on the project itself but in regards to rtf generation, memory usage and such do you see any advantages to using a webservice to do the blunt of the work? Thanks again for the time and information. Steve -----Original Message----- From: Discussion of advanced .NET topics.

I've seen suggestions that GC.Collect be called when done with large chunks of memory or large complex objects that are only allocated once per invocation.
