كود لمعرفة الرقم التسلسلي للهارد

[medreg]

السلام عليكم ورحمة الله تعالى
هذا الكود يعمل على الويندوز xp
ولكن لا يعمل على الويندوز 7
وكأن البرنامج المستعمل فيه ليس به كود الحماية

في الويندوز xp يظهر رقم الهارد ديسك في Edit حتى يتم جلب رمز التشفير
وفي الويندوز 7 لا يظهر رقم الهارد ديسك يعني تظهر edit فارغة
وبناء على وجود edit فارغة بمجرد الضغط على زر الدخول الى البرنامج يدخل عادي بدون طلب رمز التشفير
