Sample Code:

// This is not alternative, this will set the default input language based on installed keyboard layouts, if

//the layout is not installed in regional settings, nothing will happen, but with LoadKeyboardLayout, the input

//language will be installed if it doesnt exist in regional and language settings.

Alternative Managed API:

//switch to Persian(IR) language

InputLanguage.CurrentInputLanguage = InputLanguage.FromCulture(new System.Globalization.CultureInfo("fa-IR"));

//switch to English(US) language

InputLanguage.CurrentInputLanguage = InputLanguage.FromCulture(new System.Globalization.CultureInfo("En-US"));
