The dictionary object can store information in pairs: key and item. Every key refers to an item. When we build a dictionary object we create a relation between a key and an item, so we can recall an item by its key.
An example
To create a dictionary object we simply do the following:
<%
Dim dicObj
set dicObj = Server.CreateObject("Scripting.Dictionary")
Now our object is ready to accept keys and items. In order to add them we use the .add method:
dicObj.add "one","firstItem"
dicObj.add "two","secondItem"
and so on.We can recall an item, by referring to its key:
response.write ("Item of key 'one' is " & dicObj.Item("one"))
%>
which will output:
Item of key 'one' is firstItem
Properties
The dictionary object has 4 properties.CompareMode is used to compare objects in the dictonary object.
Count returns the number of items in the object.
Item returns the item.
Key sets a new key value for an already existing key.
Methods
Let's now see the methods for the dictionary object.Add adds a new pair (as seen in the example).
Exists returns a boolean value indicating if a key exists in the object.
Items returns the array of items.
Keys returns the array of keys.
Remove removes a key/item pair from the object.
RemoveAll removes all the pairs from the object.
