Re: Just a tidbit for those who might not have use iif before
I'm assuming there is a noticeable difference in using IFF? Recently I've been
using it quite heavily in forms now i.e.
cfinput type=radio name=myField id=myField value=myValue
checked=#IIF(something eq 'somethingelse', DE('Yes'), DE('No'))# /
Are there better ways of doing this?

checked=#something eq 'somethingelse#
That should work just fine. No need for the iff() in this case.

Re: Just a tidbit for those who might not have use iif before
First better way: Don't use strings for booleans!
cfinput type=radio name=myField id=myField value=myValue
checked=#IIF(something eq 'somethingelse', 1, 0)# /
Second better way: Don't write if True then True else False!
cfinput type=radio name=myField id=myField value=myValue
checked=#(something eq 'somethingelse')# /
(parenthesis are unnecessary here, but I feel they make it more readable)
Third better way: Don't use cfform!
form:select id=myField options=myValue value=somethingelse/
(that's from my form custom tag library, not yet released)
:)

Just a tidbit for those who might not have use iif before
I have never really used iif before, I was aware it existed but didn't really see a good place for it. Until today. =) Check this out: dollarformat(iif(Cost, cost, 0)) That says, evaluate cost as a Boolean, if its true (anything but 0 or null) then return cost, otherwise return 0 (so the dollarFormat does not break) This is great instead of a cfif around the whole thing. Kinda cool =) Chris ~| Deploy Web Applications Quickly across the enterprise with ColdFusion MX7 Flex 2 Free Trial http://www.adobe.com/products/coldfusion/flex2/?sdid=RVJU Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:273435 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Uh oh. You're probably about to get hammered with responses related to the performance cost...

RE: Just a tidbit for those who might not have use iif before
dollarformat(iif(Cost, cost, 0)) You could also use the val() function around the cost variable to do the same thing more efficiently. It will also correct for unexpected non-integer characters in the variable as well. I've found that in almost any situation where iif() looks like it's needed, there's a better way. There are exceptions, but I don't think this is one of them. -Justin Scott ~| Create Web Applications With ColdFusion MX7 Flex 2. Build powerful, scalable RIAs.
