The Dictionary Object
To store information in
name/value pairs (referred to as key and item),the Dictionary object is used. The Dictionary
object is a more desirable solution to manipulate related data.However,this
object might seem similar to Arrays.
Comparing Dictionaries and Arrays:
To identify the items in a Dictionary
object,keys are used
To change the size of the Dictionary object,you do not have to call ReDim
When deleting an item from a Dictionary, the remaining
items will automatically shift up
Dictionaries cannot be multidimensional, Arrays can
Dictionaries have more built-in functions than Arrays
Dictionaries work better than arrays on accessing random
elements frequently
Dictionaries work better than arrays on locating items
by their content
The following example creates a Dictionary object, adds some
key/item pairs to it, and retrieves the item value for the key gr:
lt;%
Dim d
Set d=Server.CreateObject("Scripting.Dictionary")
d.Add "re","Red"
d.Add "gr","Green"
d.Add "bl","Blue"
d.Add "pi","Pink"
Response.Write("The value of key gr is: " & d.Item("gr"))
%>
Output:
The value of key gr is: Green
