Sterling Ledet is offering a class entitled "Using ColdFusion or Java with PDF files and eForms". If you work with PDF files and forms check this out (select "ColdFusion - Using ColdFusion or Java with PDF files and eForms" from the drop down).
I'll be in the U.K. briefly next month (on my way back from India), and will use the opportunity to present ColdFusion and Flex 2 to the new Thames Valley CFUG. The event is on September 12th and registration is required.
DateDiff() is usually used to perform date difference calculations. But for simple difference calculations you can subtract dates from each other, like this:
<cfset mydate=CreateDate(2006,8,17)>
<cfoutput>#Now()-mydate# days since #DateFormat(mydate)#</cfoutput>
The returned number will likely not be an integer, and will contain date fractions too, so you may want to use Int() to round the number to just the integer portion:
<cfset mydate=CreateDate(2006,8,17)>
<cfoutput>#Int(Now()-mydate)#</cfoutput>
