There's no difference between this: <cfset obj = createObject("component","path.to.myCFC") /> <cfset result = obj.someMethod(42) /> and: <cfobject action="create" component="path.to.myCFC" name="obj" /> <cfinvoke component="#obj#" method="someMethod" theArgument="42" returnvariable="result" /> other than stylistic preference. I prefer the former as I think it is clearer (and it is less typing). Oh, and for <cfinvoke> you have to know the argument names for the method whereas you do not need to know them for the script-style call - you only have to know their order. Note the use of #obj# as the component argument in the <cfinvoke> too, to reuse the instance that is already created. If you do this: <cfinvoke component="path.to.myCFC" method="someMethod" theArgument="42" returnvariable="result" /> then you are creating a new instance of the CFC (and throwing it away after calling 'someMethod'). It is the equivalent of: <cfset aTemporaryVariable = createObject("component","path.to.myCFC") /> <cfset result = aTemporaryVariable.someMethod(42) /> (and then never using aTemporaryVariable again).
