كود تشغيل البرنامج بمجرد تشغيل الويندوز

[عنـ الشوق ـاد]

تعتمد هذه الدالة على كتابة اسم البرنامج في الريجستري الخاص بالويندوز عن طريق الدالة RegSetValueEx ، وذلك في واحد من المسارات التي تستخدم لكتابة برامج بدء التشغيل مثل المكان التالي
\Software\Microsoft\Windows\Currentversion\run
والموجود في HKEY_LOCAL_MACHINE .

والباقي أوامر مخصصة للتعامع مع مكتبات الريجستري .
