Installer.BeforeUninstall Event

Occurs before the installers in the Installers property perform their uninstall operations.

Namespace: System.Configuration.Install
Assembly: System.Configuration.Install (in system.configuration.install.dll)

'Declaration
Public Event BeforeUninstall As InstallEventHandler
'Usage
Dim instance As Installer
Dim handler As InstallEventHandler

AddHandler instance.BeforeUninstall, handler

/** @event */
public void add_BeforeUninstall (InstallEventHandler value)

/** @event */
public void remove_BeforeUninstall (InstallEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The following example demonstrates the BeforeUninstall event. It is raised by the OnBeforeUninstall method.

' MyInstaller is derived from the class 'Installer'.
Sub New()
   MyBase.New()
   AddHandler BeforeUninstall, AddressOf BeforeUninstallEventHandler
End Sub 'New

Private Sub BeforeUninstallEventHandler(sender As Object, e As InstallEventArgs)
   ' Add steps to perform any actions before the Uninstall process.
   Console.WriteLine("Code for BeforeUninstallEventHandler")
End Sub 'BeforeUninstallEventHandler

// MyInstaller is derived from the class 'Installer'.
MyInstaller()
{
    this.add_BeforeUninstall(
        new InstallEventHandler(BeforeUninstallEventHandler));
 //MyInstaller

private void BeforeUninstallEventHandler(Object sender, InstallEventArgs e)
{
    // Add steps to perform any actions before the Uninstall process.
    Console.WriteLine("Code for BeforeUninstallEventHandler");
 //BeforeUninstallEventHandler
