Re: Evaluate vs ?
if you generate the content files and save them as static files, you can just cfinclude them into your cfmail then you won't need to evaluate them. BTW, if your sending out that much mail, I hope you have a dedicated SMTP server and are not using the SMTP on IIS.

Re: Evaluate vs ?
Performance on the mailer is a lot slower than I'd like, and I suspect its because I'm using evaluate. Here is a test I made on my develop system (3000 MHz): CFSET myStruct = structNew () CFSET myStruct.myvar = test CFSET start = GetTickCount() CFLOOP INDEX=i FROM=1 TO=10 CFSET test = evaluate (mystruct.myvar ) /CFLOOP CFOUTPUTTime = #numberFormat(GetTickCount()-start, 999)#BR/CFOUTPUT CFSET start = GetTickCount() CFLOOP INDEX=i FROM=1 TO=10 CFSET test = mystruct['myvar' ] /CFLOOP CFOUTPUTTime = #numberFormat(GetTickCount()-start, 999)#BR/CFOUTPUT The results are (in avarage): Time = 530 msec Time = 200 msec This show that 1. evaluate takes more than twice the double than struct notation; 2. the difference is about 1/3 sec for 10 iteration, then, unless you really use evaluate in some million iterations loop, the difference is not really significant. There are many other places to look for optimization, the first being queries and correct indexes in the database. -- ___ REUSE CODE!

RE: Evaluate vs ?
Dave Watts said: What's the matter with using evaluate? It's generally more expensive to tell the computer to treat a literal string as an expression, than to just give the computer an expression in the first place. I think the bigger issue is the question where that string expression originates. With the example posted by Stan doesn't pose much risk, we have probably all seen the following code: cfloop list=#form.fieldnames# index=currentField set Quantity = Evaluate(currentField) /cfloop In this example, you are essentially running user generated code inside your website. It is still limited to whatever Evaluate() accepts, but you can get all sorts of interesting information if you submit a form with a field named StructKeyList(session) or StructClear(application).

Basically it is calling a setter method based on what is in the a structure.

This is untested, but you should be able to do:
cfloop collection=struct_Params item=theKey

cfset doMethod = myObject[set theKey] /
!---// execute the method //---
cfset doMethod(struct_Params[theKey]) /

The same it's true for whenever you want to dynamically generate the arguments. Don't get me wrong, I prefer dot notation myself (I find it easier to read), but cfinvoke is handy on certain cases.

Re: Evaluate vs ?
Dan, This was close, but acts strange. I can do the following: cfoutput #myObject.getFirstName()# --- outputs correctly. cfset getter = FirstName / cfset doMethod = myObject[get getter] / cfset myFN = doMethod() / --- throws error #myFN# /cfoutput The error thrown by the doMethod() line is coming from the Object CFC. It says it that variables.FirstName is not defined, which is what the getter is getting. It is as though it doesn't recognize it as the same object. Massimo - I don't use cfinvoke much as I'm usually within a cfscript block. However I'm not against trying it. How does cfinvoke refer to an object instance.

RE: Evaluate vs ?
Is there a time when evaluate should be used? Nick's answer is pretty much on target. It used to be the case that you needed to do this, because in some cases you had no way to reference variable names when you didn't know them until runtime. As CF's scopes became exposed as structures, the need to do this has diminished significantly. That said, there presumably may be a time when you want to take an arbitrary string and treat it as an expression, and Evaluate will be there for you.

You really don't even need the val() function.
Using a foreach loop dramatically increases the speed of looping through
collections.
form action=myform.cfm method=post
input type=text name=quantity_1
input type=text name=quantity_2
input type=text name=quantity_3
input type=text name=quantity_4
input type=submit name=submit
/form
cfscript
if(isDefined('form.fieldnames')) {
// remove elements that you don't want
structDelete(form,'fieldnames');
structDelete(form,'submit');
structDelete(form,'searchstring');
for(it IN form) {
writeOutput(it ':' form[it] 'br /');
}
}
