Description: A list of some of the more frequently used prefixes. Adhering to a formal naming convention assists in improving code clarity. Remember, although the code you write today may be easy to understand; if someone else reads it or you need to modify it a year from now could you remember what each of those controls and variables was used for?
Controls needed: N/A
Level: All Levels.

** This is longer than the 'ideal' three letter prefix -but it is clear. You could certainly create your own prefix for this (like imc)-or any other control. Just remember that another programmer who views your code will probably understand something like txtDescription but may not understand your custom prefix of zqeDescription -be sensible.
