السلام عليكمورحمة الله
عند صناعة اداة جديدة اريد ان اعرف الفورم الذي تم وضع الاداة عليه لاقوم بعمل تغيرات به
عند صناعة UserControl كنت استخدم ParentForm
انما لو انا بعمل كمبو بوكس مثلا لم اجد ParentForm
وجزاكم الله خيرا

' This example uses the Parent property and the Find method of Control to set

    ' the event handler method defined in the example.
