If you are using Windows 2000 Server on your network you probably have Active Directory installed. Active Directory is Win2K's Directory Service, and it'll typically store data on users, groups, and more. ColdFusion users can access the data in Active Directory without having to use any special...
When the expression is evaluated, what will the value of x be? Is it 50 (9 times 6 is 54, minus 4 is 50), or 18 (6 minus 4 is 2, times 9 is 18)? The value is actually 50, but as you can see, order of evaluation makes a big difference. For this reason you should always use parenthesize to explicitly...
Familiar with the REQUEST scope? This variable type (introduced in ColdFusion 4.01) is much like the VARIABLES scope in that it persists until a request has finished processing, but unlike VARIABLES it is visible to all pages that are part of a request (even Custom Tags). And you can use REQUEST...
ColdFusion has two division operators, / and , and they are not the same. / is the standard division operator, divides a number and returns whole numbers only (integers, no fractions). So if you code x will be 3.33333333333, but if you code x will be 3. (Applies to: ColdFusion All)

Ever wondered what to do with those VTM files that come with many of the Custom Tags out there? VTM files are used by ColdFusion Studio (and HomeSite) to display Tag Editors - the dialogs that are displayed when you right click on a tag and select Edit. How do you use VTM files? Simply drop them...
The ColdFusion tag is used to group a set of SQL statements that need to be executed as a batch (allowing for rollbacks and explicit commits). But before you use this tag, stop and think - do you really need to do this? Could you process the entire set of statements within a stored procedure...
ColdFusion Studio caches VTM files (to improve performance). If you are creating and testing VTM's you'll need to flush the cache frequently so as to be able to test your changes. Instead of quitting and restarting Studio, you can use the following keystrokes to flush the cache: Ctrl + Alt + Shift...
If you are running ColdFusion on a Unix system (Linux, for example) then you must pay special attention to file names and their case-sensitivity. This is especially important when using special files like "Application.cfm" in which case the file must be spelled like that exactly, any other spelling...
