    InputLanguageManager.CurrentInputLanguage = InputLanguageManager.InstalledInputLanguages(2)
    Dim variable As String = urdu.Text
End Sub

Answer 1

Assuming that Urdu is already installed on your system. You can try like this:

Public Sub urdu_GotFocus(ByVal InputLang As InputLanguage)
   If InputLanguage.InstalledInputLanguages.IndexOf(InputLang) = -1 Then
        Throw New ArgumentOutOfRangeException()
   End If
    InputLanguage.CurrentInputLanguage = InputLang
End Sub

Note that InputLanguage is present in System.Windows.Forms namespace and in System.Windows.Forms.dll assembly.
