Does StructClear reset keys in a structure to be blank, or does it remove
the keys? Also, what's a function to get rid of a structure altogether?
Thank you

I thought I had read that this line of code no longer works well in 4.5, is
this true?
Is there a better alternative? Should I be surrounding this with ?

StructClear destroys struct keys. As for deleting structures altogether,
I'm not sure. Surely there's got to be a way to unset variables, right?

It removes keys and values.

I don't think there is one. You could overwrite a structure with a simple
value:

The StructClear() function completely empties a structure; keys and
everything. Let's extend this for a second. Take the following situation:
A structure with 2 keys, right? Now, you can clear this structure one of
two ways:
There is an important distin
StructDelete(structure, key) :)
If you wanted to clear the structe you COULD
And you are left with a mere shell of
the structure you once had :)
Or you can use StructClear which clears
out the *data* only.

Not quite true. Just ran a test and StructClear deletes the keys just like
your loop does. Here is code you stick on any template to try:
<CFSET myStruct = StructNew()>
<CFSET myStruct.data = "somedata">
alert("#IsDefined('myStruct.data')#");

Loopi
This is not true. :) The StructClear() function does the exact same thing
your loop does - it completely empties the structure of both keys and values
(data). Don't believe me? Try it:
#StructCount(Bag)#
#StructCount(Bag)#
You will get the following result:
100
0
Just 'cause I'm on a run of disagreeing with Jeremy today ... ;)

It works, but too well. It also clears out session vars that ColdFusion uses
to track you. You should either use StructDelete to remove individual
variables, or simply store all of your stuff in a substructure, like
Session.MyVars. Then you can call StructClear on that structure w/o any
worries

Any time you read or write to memory variables (session, application,
server) you should use CFLOCK. If you're using CF 4.5, you should use the

I have forwarded to Michael a series of posts made to the Fusebox list some
time ago about locking access to shared variable access.
If anyone else is interested just let me know.

Hi,
Recently someone said that StructClear(session) was a bad way to remove
session variables. Why? If I effectively want to remove an entire session
(this is ti be used in a logout template), wouldn't StructClear(Session) be
the way to do it?

I actually just needed to delete a structure, so I read up a little and
tried out some cfdumps, and according to Jedi Master Forta (Web Application
Construction Kit, 4th Ed), StructClear just erases the current user's
session (and everything in it.) It doesn't erase all session variab

What type of lock is used with StructClear(Session)? Is it ReadOnly or
Exclusive?

Tage,
If you run a the StructClear() against the session scope
you will lose ALL the session keys, including the session
ID, CFID and CFTOKEN. Once these are gone, it is impossible
to then associate a user with a session.
Good luck,
Beau

Using StructClear(session) clears out the entire session scope, including sessionID,
CFID & CFTOKEN - if this is what you want, great.
It's important to use StructClear(session.structName) if you want to clear only a
single structure in the session scope.

When the user logs in I run the following code...
I first check to see if the user exisits. If so...
Then I set some session variables
