Installer.BeforeUninstall Event
.NET Framework 2.0
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)
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
