Hashtable: Item (let)

Item

Sets the value associated with the specified key.



 Public Property Let Item(
	  ByRef Key As Variant,
	  ByRef Value As Variant )

Parameters

Key
[ByRef] Variant. The key whose value to get.
Value
[ByRef] Variant. The value associated with the specified key. If the specified key is not found, attempting to get it returns Empty, and attempting to set it creates a new element using the specified key.

Remarks

This property provides the ability to access a specific element in the collection by using the following syntax: myCollection(key).

You can also use the Item property to add new elements by setting the value of a key that does not exist in the Hashtable; for example, myCollection("myNonexistentKey") = myValue. However, if the specified key already exists in the Hashtable, setting the Item property overwrites the old value. In contrast, the Add method does not modify existing elements.

To distinguish between Empty that is returned because the specified key is not found and Empty that is returned because the value of the specified key is Empty, use the Contains method or the ContainsKey method to determine if the key exists in the list.

Retrieving the value of this property is an O(1) operation; setting the property is also an O(1) operation.
