Raises the OnBeforeRollback event.
[Visual Basic] Overridable Protected Sub OnBeforeRollback( _ ByVal savedState As IDictionary _ ) [C#] protected virtual void OnBeforeRollback( IDictionary savedState ); [C++] protected: virtual void OnBeforeRollback( IDictionary* savedState ); [JScript] protected function OnBeforeRollback( savedState : IDictionary );
This method is called before rolling back the installations that were done by the installers in this instance's InstallerCollection.
Raising the event invokes an event-handling method through a delegate. For an overview, see EventTopicTBD.
Notes to Inheritors: When overriding OnBeforeInstall in a derived class, be sure to call the base class's OnBeforeRollback method.
