RE: When is a struct not a struct ?
>>Hmm, so how can I reliably tell I'm holding a struct and not a CFC ? >>isStruct() and not isObject() ? I think you can tell when you are holding a struct and not a CFC like this: this is a struct this is an Object Since isObject() will only return true if it is an object, if you check both of them to confirm you have a structure, you will know for sure. Of course, if you just interrogate isStruct() then you won't know for sure, but if you check both, you will since we have proven that isObject() returns false on a structure, even if you have loaded it with functions to make it LOOK like an object. Of course, if you're checking to see if something is an object, you don't have to check both, you can just do isObject(), but in your case, I think you want to know if it is a structure and I think based on what we've seen, to be 100% sure, you have to do both.

Re: When is a struct not a struct ?
CFCs can also be treated as structures for most purposes. StructKeyExists(), StructKeyList(), etc. will all work on a CFC instance.

RE: When is a struct not a struct ?
>> From my understanding, I thought an object was a special kind of structure - a structure with processes (methods). On the other hand, it may look and act like an object, but it isn't one. The code below shows that you can create a structure that 'looks' like an object, (with what appears to be a method, but is really just a reference to a UDF), but doesn't return true for isObject(). I think this is right behavior. This is also a good example of why it's good to prefix variables because if you saw stDate.getDate() without st in front of it, you would probably start looking for a createObject() function somewhere but would never find it. #isStruct(stDate)# #isObject(stDate)# #stDate.getDate()# ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:310114 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

RE: When is a struct not a struct?
When you call duplicate(cfcatch) it returns a structure. Then you can pass it to a UDF where the argument type is struct and use all struct functions on it. That's also how cfdump works. If it gets an exception, it duplicates it.

RE: When is a struct not a struct?
You might try creating an empty struct and then setting the CFCATCH into it: foo = structNew(); foo = cfcatch; Alternately, you could just use the new struct as a wrapper: foo = structNew(); foor['error'] = cfcatch; I haven't tried either, but if the first doesn't work, the second almost certainly will. you'll just have to unwrap the error on the other side... -Cameron - Cameron Childress Sumo Consulting Inc --- land: 858.509.3098 cell: 678.637.5072 aim: cameroncf email: [EMAIL PROTECTED] -Original Message- From: Craig Earls [mailto:[EMAIL PROTECTED] Sent: Friday, February 06, 2004 7:31 PM To: CF-Talk Subject: When is a struct not a struct?
