InputLanguageChangedEventHandler Delegate

Represents the method that will handle the InputLanguageChanged event of a Form.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

'Declaration
Public Delegate Sub InputLanguageChangedEventHandler ( _
	sender As Object, _
	e As InputLanguageChangedEventArgs _
)
'Usage
Dim instance As New InputLanguageChangedEventHandler(AddressOf HandlerMethod)

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.Windows.Forms.InputLanguageChangedEventArgs

An InputLanguageChangedEventArgs that contains the event data.

When you create an InputLanguageChangedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.

For more information about event-handler delegates, see Events and Delegates.

The following example creates a new Form and attaches an event handler to the InputLanguageChanged event. This event changes the IMEmode when the input language changes to Japanese.

      rtb.Dock = DockStyle.Fill
   End Sub 

   Private Sub languageChange( _
      ByVal sender As Object, _
      ByVal e As InputLanguageChangedEventArgs _
   ) Handles MyBase.InputLanguageChanged

      ' If the input language is Japanese. 
      ' set the initial IMEMode to Katakana. 
      If e.InputLanguage.Culture.TwoLetterISOLanguageName.Equals("ja") = True Then
         rtb.ImeMode = System.Windows.Forms.ImeMode.Katakana
      End If 
   End Sub

      Application.Run(new Form1())
   End Sub
