مساعدة في Dialogs في VC++ 6.0

السلام عليكم

اريد ان اعمل برنامج يتعامل مع Singly Linked List بشكل مبسط جداً باستخدام ال Dialogs فقط .

رسمت زر لانشاء List جديدة وزر آخر لاضافة عنصر Add First .

المشكلة الآن هي اين اضع الكود الخاص بانشاء قائمة جديدة ( يعني object من نوع class Singly ) وايضاً اين اضع الكود الخاص باضافة عنصر جديد ؟

للتوضيح ، هذه هي الواجهة :

و هذه هي ال Workspace :

الملفات التي عدلت عليها هي كتالي :

طبعا هناك خطأ في الدالة Add First بسبب الربط بينه وبين class singly .. وايضاً ادخال القيمة ال data لم أقم بعمله حتى الآن ، لكن المطلوب شرحه هو كيف أقوم بدمج الكود ؟ وماهي الطريقة الصحيحة ؟
