ColdFusion MX runs on underlying Java, and so the JVM and its settings are really important. For this reason the JVM configuration file is backed up each time you save changes in the Java and JVM Settings page in ColdFusion Administrator. You can restore these settings as needed. (Applies to:...
To read and write localized file be sure to specify the encoding to be used in the tags ENCODING attribute. (Applies to: ColdFusion MX)
ColdFusion Components (and their functions and arguments) may have underscores in their names, but Web Services shouldn't. So, just to be safe, don't use any non-alphanumeric characters in names in your CFC's, just in case you opt to make them accessible as Web Services at a later date. (Applies...
ColdFusion uses CFID and CFTOKEN to uniquely identify sessions, CFID is an incremental number and CFTOKEN is a random number (the combination of which make a unique session). CFTOKEN values may not be unique (CFID always will be) - but for added safety you can make CFTOKEN unique too by checking...
If you are creating Web Services in .NET for consumption by ColdFusion, do not use the dataset data type as this is only supported by .NET languages. (Applies to: ColdFusion MX)
The CFML Encrypt() and Decrypt() functions will not work with double byte data - no error will be thrown, but encrypted data will not decrypt properly. (Applies to: ColdFusion MX)
ColdFusion MX uses JDBC, not ODBC. Want to use your ODBC data sources with CFMX? You can. Here's what you need to do: 1) Create the ODBC data source (using Windows Control Panel), and 2) add a data source in ColdFusion MX Administrator of type "ODBC Socket" specifying the name of the ODBC data...
Strings do not usually contain NUL (ASCII 0) characters, but if they do you should be aware of a change to the Len() function. ColdFusion 5 (and earlier) returned the length up to the NUL, ColdFusion MX returns the complete string length (even characters after the NUL). (Applies to: ColdFusion MX)
Query columns can be treated as arrays, and the IsArray() function will return TRUE if the argument is a query column. (Applies to: ColdFusion MX)
The GetTempDirectory() function returns the name of a directory that can be used to store temporary files. On Windows boxes ColdFusion used to return the Windows temp directory - in ColdFusion MX the directory returned will be the temporary directory of the underlying J2EE server. (Applies to:...
