Thanks Allen.
Regarding "But, that being said, if the second one worked, you now have a scoped thread that you can reference without hunting." Do I understand correctly that <cfset myScope = StructNew() /> <cfset myScope.MyNewVar = "bla"> <cfoutput>#myScope.MyNewVar#</cfoutput> Is considered scoping a variable? I thought it had to be prefixed with request. or variables.? I would think that if you have a udf on your page named MyScope that returns a structure with a key named MyNewVar, that that would take precedence, per http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec09af4-7fdf.html ?

I don't remember the exact order, but it does happen. But, that being said, if the second one worked, you now have a scoped thread that you can reference without hunting. It used to be the "variables" scope was used for all unscoped variables. Doesn't seem to be the case any more but I haven't really paid any attention to it until I saw this thread. If creating a struct and naming the thread as a member of that stuct works, you should be good to go. I will warn though - make sure it also works on CF9 - I've had some things fail that were "scoped functions" on CF9 with insanely obscure errors (these worked with no problem in CF8). I won't go into detail here unless someone wants to know specifics, but make sure you test on 8 and 9.

The code you refer to uses unscoped variables, which causes scope hunting. Mischa. Date: Thu, 26 May 2011 08:25:00 -0400 Subject: Re: [ACFUG Discuss] CFThread name issue From: [email protected] To: [email protected] A thread is a "forked" process... the whole point of running something in a thread is usually that you what to "fire and forget" Ie do some batch stuff then email the results. OR you want to fork to multiple threads and have them do the batch in multiple threads (possibly shortening your batch by the number of threads you spawn) If you want to find out how long that thread took to process it you can always cflog the results... the CF docs have an example of doing what you want: http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=Tags_t_04.html On Wed, May 25, 2011 at 5:51 PM, Mischa Uppelschoten <[email protected]> wrote: I think this is more about naming the thread itself than passing values into it.

From: [email protected] To: [email protected] Date: Wed, 25 May 2011 16:19:23 -0500 Subject: RE: [ACFUG Discuss] CFThread name issue I’m thinking that when you send something to thread, you have divorced it from the request scope entirely, hence, your inability to reference it as a request scope variable even with a syntactically correct var name. Based on what you’re posting, I’d say scoping it into variables would solve the problem, yes? Or am I misunderstanding what you’re saying completely?
