Installer.AfterRollback Event
Occurs after the installations of all the installers in the Installers property are rolled back.
Assembly: System.Configuration.Install (in System.Configuration.Install.dll)
The following example demonstrates the AfterRollback event. It overrides the Install method and explicitly throws an ArgumentException so that the Rollback method is called. When the Rollback is completed, the AfterRollback event occurs and a message is displayed.
Imports System Imports System.Collections Imports System.ComponentModel Imports System.Configuration.Install ' Set 'RunInstaller' attribute to true. <RunInstaller(True)> _ Public Class MyInstallerClass Inherits Installer Public Sub New() MyBase.New() ' Attach the 'AfterRollback' event. AddHandler Me.AfterRollback, AddressOf MyInstaller_AfterRollBack End Sub 'New ' Event handler for 'AfterRollback' event. Private Sub MyInstaller_AfterRollBack(sender As Object, e As InstallEventArgs) Console.WriteLine("") Console.WriteLine("AfterRollBack Event occured.") Console.WriteLine("") End Sub 'MyInstaller_AfterRollBack ' Override the 'Install' method. Public Overrides Sub Install(savedState As IDictionary) MyBase.Install(savedState) ' Explicitly throw an exception so that roll back is called. Throw New ArgumentException("Arg Exception") End Sub 'Install ' Override the 'Commit' method.
