The ColdFusion Migration Wizard is run the first time the ColdFusion MX Administrator is executed. To force it to run again on Windows set registry key HKEY_LOCAL_MACHINESOFTWAREMacromediaInstall DataNeomigrate to 1, on Unix boxes create a file named "upgrade" in the ColdFusion bin directory (the...
The tag is used to embed a Java applets in your Web page. This tag has always been usable only within tags, but ColdFusion MX now allows the tag to be used anywhere - not just in forms. (Applies to: ColdFusion MX)
User-defined functions (UDF’s) may return a single result via the tag (or the return statement if using ). To return multiple results place them in a structure as name=value pairs and then return the structure. (Applies to: ColdFusion MX)
Within a user-defined function (UDF) arguments may be accessed in two different ways – by simply specifying the argument name (either with or without the ARGUMENTS prefix), or as elements of an array named "arguments" (the first element would be argument[1]). (Applies to: ColdFusion MX)
As a rule, don't use two digit years - full four digit years are much safer. But if you do use two digit years, be aware that ColdFusion MX has changed the way they are processed. In CF5 and earlier years 0-29 are previous century and 30-99 are current century. In CFMX years 0-20 are previous...
To specify hexadecimal numbers for use within a regular expression format the number as xdd where dd is the number. Octal numbers may be specified the same way using ddd. (Applies to: ColdFusion MX)
ColdFusion MX uses UTF-8 as its default character encoding as this encoding can handle both ASCII and Unicode correctly. CF5 (and earlier) used ISO-8859-1 encoding, and this change could affect the way some upper ASCII characters are displayed. If you run into this problem you can force CF to use...
tags may have explicit timeout values specified in the TIMEOUT attribute. ColdFusion 5 (and earlier) accepted a timeout value in milliseconds, ColdFusion MX uses seconds. As such, if you are using this attribute you must change your code (or your timeout will be a thousands times longer than...
The date/time object in CF5 (and earlier) was accurate to seconds only - milliseconds were dropped. This has been changed in CFMX - milliseconds are now retained. To drop the milliseconds (to mimic former functionality) use the DateFormat() function. (Applies to: ColdFusion MX)
ColdFusion User Defined Functions may be named using any valid variable name, with one notable exception. User Defined Functions (created using or ) may not have a name that starts with the letters "cf" as these names are reserved. (Applies to: ColdFusion 5 or later)
