The Dictionary object stores information in name/value pairs. The Asp dictionary object allows you to store information in data key, item pairs. The Dictionary object is like an associative array, but with its own built-in functionality. This dictionary object also looks after the basic tasks of storing and manipulating the data, and sizing for the required number of elements. However, the Dictionary object is a more desirable solution to manipulate related data. Also you should know that each item in the Dictionary object is associated with a unique key.

Before using the dictionary object, there are somethings that should be kept in mind. These things are described as follows :

1. You cannot use key for the another item in the same Dictionary object, since the key is a unique identifier for the corresponding item. If you create a duplicate, then the old value of that object will get overwritten with the new one that you re-placed recently.
2. Since the dictionary cannot be multidimensional, a value in a Dictionary object can not be an array.

The following are some Asp Dictionary Object Methods :

• Add - This method adds a key and item pair to a Dictionary object.
• Remove - This method is used for removing a key, item pair from a Dictionary object.
• RemoveAll - This method is used for removing all key, item pairs from a Dictionary object.
• Items - This method returns an array containing all the items in a Dictionary object.
• Exists - This method returns True if a specified key exists in the Dictionary object; False if it does not.
• Keys - This method returns an array containing all existing keys in a Dictionary object.

According to me, you should also know the properties of Asp Dictionary Object. So I have mentioned the properties below :

1. Count - This property returns the number of items in a collection or Dictionary object.
2. Item - This property sets or returns an item for a specified key in a Dictionary object.
3. Key - This property sets a key in a Dictionary object.
4. CompareMode - This property sets and returns the comparison mode for comparing string keys in a Dictionary object.

Hope that this will help you..!!

For creating the dictionary object, you can use the following code :

<%
Dim objDictionary
Set objDictionary = CreateObject(Scripting.Dictionary)
objDictionary.Add "pet", "Cat"
objDictionary.Add "jeep", "Scorpio"

dim strkey,strvalue
strkey = "Flower"
strvalue = "Rose"
objDictionary.Add strkey,strvalue
%>
