	finished As Boolean _
)
'Usage
Dim token As String
Dim finished As Boolean

Dim instance As New Authorization(token, finished)
public Authorization (

	boolean finished
)
public function Authorization (
	token : String, 
	finished : boolean
)

Parameters

token

The encrypted authorization message expected by the server.

finished

The completion status of the authorization attempt. true if the authorization attempt is complete; otherwise, false.

The Authorization instance is created with the Message property set to token and the Complete property set to finished.

The following code example creates a new instance of the Authorization class with the specified authorization message and completion status.
