InputLanguageChangingEventArgs Class

Provides data for the InputLanguageChanging event.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public class InputLanguageChangingEventArgs : CancelEventArgs
public class InputLanguageChangingEventArgs extends CancelEventArgs
public class InputLanguageChangingEventArgs extends CancelEventArgs
Not applicable.

You can use the data from the InputLanguageChangingEventArgs class to prepare to change Input Method Editors (IME) or swap right-to-left values. You can also change a thread's CurrentCulture and CurrentUICulture properties so that different resources get picked up. To prevent the input language from changing, set the Cancel property to true.

An InputLanguageChangingEventArgs identifies the requested input language and the character set of new input language. The Culture property identifies the locale of the requested language.

The InputLanguageChanging event precedes the InputLanguageChanged event.

For information about handling events, see Consuming Events.

The following code example demonstrates the use of this type. In the example, an event handler reports on the occurrence of the InputLanguageChanging 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 Show with System.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 InputLanguageChanging event.

private void Form1_InputLanguageChanging(Object sender, InputLanguageChangingEventArgs 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}", "SysCharSet", e.SysCharSet );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "InputLanguageChanging Event" );
}
