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

Syntax

Visual Basic

Public Event InputLanguageChanged As InputLanguageChangedEventHandler

public event InputLanguageChangedEventHandler InputLanguageChanged

Visual C++

public:
 event InputLanguageChangedEventHandler^ InputLanguageChanged {
    void add (InputLanguageChangedEventHandler^ value);
    void remove (InputLanguageChangedEventHandler^ value);
}

member InputLanguageChanged : IEvent<InputLanguageChangedEventHandler,
    InputLanguageChangedEventArgs>

Remarks

You can use this event to make changes to your form's appearance and text based on changes made to the input language of the form.

For more information about handling events, see Consuming Events.

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the InputLanguageChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox..::.Show with Console..::.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type Form named Form1. Then ensure that the event handler is associated with the InputLanguageChanged event.

Visual Basic

Private Sub Form1_InputLanguageChanged(sender as Object, e as InputLanguageChangedEventArgs) _ 
     Handles Form1.InputLanguageChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "InputLanguage", e.InputLanguage)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Culture", e.Culture)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "CharSet", e.CharSet)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"InputLanguageChanged Event")

End Sub

private void Form1_InputLanguageChanged(Object sender, InputLanguageChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "InputLanguage", e.InputLanguage );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Culture", e.Culture );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "CharSet", e.CharSet );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "InputLanguageChanged Event" );
}
