Public Module TextBoxBaseExtensions
    <System.Runtime.CompilerServices.Extension>
    Public Sub SetText(this As TextBoxBase, value As String)
        Static forceWindowText As System.Reflection.MethodInfo = GetType(System.Windows.Forms.TextBoxBase).GetMethod("ForceWindowText", System.Reflection.BindingFlags.NonPublic Or System.Reflection.BindingFlags.Instance)
        forceWindowText.Invoke(this, New Object(0) {value})
    End Sub
End Module
