Remarks

Notes to Inheritors:

If you override the Install method in a derived class, be sure to call the base class's Install method first in your derived method. The Install method calls the Install method of each installer contained in the Installers property of this instance. After the contained installers run, this method updates the IDictionary object (specified through the stateSaver parameter) to reflect the status of the installation. The IDictionary should be empty when passed to the Install method. If all the Install methods succeed, the Commit method is called. Otherwise, the Rollback method is called.
If you need to add installer instances to the Installers collection in the Install method, be sure to perform the same additions to the collection in the Uninstall method. However, you can avoid maintaining the collection in both methods if you add installer instances to the Installers collection in the class constructor for your custom installer.

Examples

The following example demonstrates the Install method of the Installer class. A class is derived from the Installer base class and the Install method is overridden.

Visual Basic

' Override the 'Install' method of the Installer class.
Public Overrides Sub Install(mySavedState As IDictionary)
   MyBase.Install(mySavedState)
   ' Code maybe written for installation of an application.
   Console.WriteLine("The Install method of 'MyInstallerSample' has been called")
End Sub 'Install

// Override the 'Install' method of the Installer class.
public override void Install( IDictionary mySavedState )
{
   base.Install( mySavedState );
   // Code maybe written for installation of an application.
   Console.WriteLine( "The Install method of 'MyInstallerSample' has been called" );
}

Visual C++

   // Override the 'Install' method of the Installer class.
public:
   virtual void Install( IDictionary^ mySavedState ) override
   {
      Installer::Install( mySavedState );
      // Code maybe written for installation of an application.
      Console::WriteLine( "The Install method of 'MyInstallerSample' has been called" );
   }
