Demonstrates how to remove one or more tags from the set of tags attached to a vault. VB.NET

Dim success As Boolean = False

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

Dim rest As New Chilkat.Rest

' Connect to the Amazon AWS REST server in the desired region.
Dim bTls As Boolean = True
Dim port As Integer = 443
Dim bAutoReconnect As Boolean = True

' Provide AWS credentials.

' --------------------------------------------------------------------------
' Note: The above REST connection and setup of the AWS credentials
' can be done once.  After connecting, any number of REST calls can be made.
' The "auto reconnect" property passed to rest.Connect indicates that if
' the connection is lost, a REST method call will automatically reconnect
' if needed.
