(VB.NET UWP/WinRT) Azure Service Bus - Unlock Message

See more Azure Service Bus Examples

Shows how to unlock a message for processing by other receivers on a specified queue or subscription. This operation deletes the lock object, causing the message to be unlocked.

For more information, see https://docs.microsoft.com/en-us/rest/api/servicebus/unlock-message

Chilkat for the Universal Windows Platform (UWP)

' Note: Requires Chilkat v9.5.0.65 or greater.

' This requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' Make the initial connection.
' A single REST object, once connected, can be used for many Azure Service Bus REST API calls.
' The auto-reconnect indicates that if the already-established HTTPS connection is closed,
' then it will be automatically re-established as needed.
Dim rest As New Chilkat.Rest
Dim bAutoReconnect As Boolean = True
Dim success As Boolean = Await rest.ConnectAsync("<yournamespace>.servicebus.windows.net",443,True,bAutoReconnect)
If (success <> True) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


' Let's load a previously computed SAS token and use it.
' See Azure Shared Access Signature for an example to genenerate an Azure SAS token.
Dim sbToken As New Chilkat.StringBuilder

' Tell the REST object to use the Azure Shared Access Signature for authorization.
sbToken.Prepend("SharedAccessSignature ")
rest.AddHeader("Authorization",sbToken.GetAsString())

' ----------------------------------------------------------------------------------------------
' The code above this comment could be placed inside a function/subroutine within the application
' because the connection does not need to be made for every request.  Once the connection is made
' the app may send many requests..
' ----------------------------------------------------------------------------------------------

' To unlock a message, we'll need either the SequenceNumber or MessageId.
' When the message was locked, the SequenceNumber and MessageId of the locked message
' was returned in the HTTP response header named "BrokerProperties, which contained
' JSON such as the following:

' 	{
' 	  "DeliveryCount": 2,
' 	  "EnqueuedSequenceNumber": 3000003,
' 	  "EnqueuedTimeUtc": "Wed, 07 Dec 2016 17:42:48 GMT",
' 	  "Label": "M2",
' 	  "LockToken": "0a13ee8a-be32-4458-89e0-5e1401caa6a0",
' 	  "LockedUntilUtc": "Wed, 07 Dec 2016 18:13:12 GMT",
' 	  "MessageId": "7bea513a6ddb49089e07bfbee26d85bd",
' 	  "SequenceNumber": 3,
' 	  "State": "Active",
' 	  "TimeToLive": 922337203685.47754
' 	}

' The path for unlocking a message is constructed as follows, depending on
' whether it is a message on a queue or subscription:
' 
' (for a queue)
' /{queuePath}/messages/{messageId|sequenceNumber}/{lockToken}
' 
' (for a subscription)
' /{topicPath}/subscriptions/{subscriptionName}/messages/{messageId|sequenceNumber}/{lockToken}

' This example will build a path to unlock a message contained in a subscription.
