Exception

Condition

The savedState parameter is nullNothingnullptra null reference (Nothing in Visual Basic).

Remarks

Notes to Inheritors:

If you override the Commit method in a derived class, be sure to call the base class's Commit method first in your derived method. The Commit method is called only if the Install method of each installer in this instance's InstallerCollection succeeds. The Commit method stores information needed to do a correct uninstallation, and calls the Commit method of each installer in the collection.

Examples

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

Visual Basic

' Override the 'Commit' method of the Installer class.
Public Overrides Sub Commit(mySavedState As IDictionary)
   MyBase.Commit(mySavedState)
   Console.WriteLine("The Commit method of 'MyInstallerSample'" + _
                                                "has been called")
End Sub 'Commit

// Override the 'Commit' method of the Installer class.
public override void Commit( IDictionary mySavedState )
{
   base.Commit( mySavedState );
   Console.WriteLine( "The Commit method of 'MyInstallerSample'"
                     + "has been called" );
}

Visual C++

// Override the 'Commit' method of the Installer class.
virtual void Commit( IDictionary^ mySavedState ) override
{
   Installer::Commit( mySavedState );
   Console::WriteLine( "The Commit method of 'MyInstallerSample' "
      "has been called" );
}
