ContainsKey

Checks if the current instance contains a specific key.

 Public Function ContainsKey(
	  ByRef Key As Variant ) As Boolean

Parameters

Key

[ByRef] Variant. The key to check for.

Return Values

Remarks

The key can be any datatype other than vbUserDefinedType. If an object is being used as a key, then it should implement the IObject interface to allow for custom hashcode creation. If the object doesnt not implement the interface, then the objects memory location is used for a hashcode. If two different objects should represent the same hashcode, then they need to implement the IObject interface and override the GetHashCode function.
