طلب مساعدة في فهم كود wimgapi.dll
#1
السلام عليكم و رحمة الله و بركاته


إخواننا العباقرة في منتدانا الجميل منتدى فيجوال بيسك ، هذه أول مشاركة لي في هذا المنتدى الكبير و كنت أود من حضراتكم المساعدة في فهم كود معين
بحث عن كود للتعامل مع ملفات Windows image و التي تستخدم في أسطوانات ويندوز 7 و 8 عن طريق مكتبة مايكروسوفت wimgapi.dll
فوجدت كوداً عبارة عن class تجمع كل وظائف هذة المكتبة الرائعة و لكن لا أعرف كيف أستخدمها لأنها تحتاج إلى نوع من فك التشفير أو ما شابه ، فأرجو لمن يعرف من
حضراتكم هذا الكود و كيفية استخدمة يفيدنا و جزاكم الله خيراً ، و الكود كالآتي :
كود :

أقصد لو أن حضرتك أردت استخدام كود مثل
wimapi.WIMGetAttributes
سيطلب كتابة بين قوسين المفروض مكان ملف wim لكنه سيطلبه بصورة system.intptr هذا ما أقصد
فكيف أحول مسار مثل C:\install.Wim إلى تلك الصيغة الرقمية؟؟

مستحيل

وظيفة intptr ليس لتحويل المسارات

انما هذا نوع من البيانات يستخدم للتعامل مع عناوين الكائنات(handle) كنوافذ البرامج وازرارها


انا لحد الان ما فهمت ويش ده windows image

هل هو سيدي الوندوز ؟؟

أنا فقط أحاول استخدام هذه الأداة للتعامل مع ملفات wim و مبرمج الفئة وضع بعض الأشياء فيها مثل
WIMGetImageCount(ByVal hwim As IntPtr) As Int32
كهذا .... استخدمت قبلا أداة imagex و كانت لتفعل ذلك الأمر لابد من معرفة أولا مكان ملف wim و هو string و فكيف يستعاض عنه بالهاندل

اعتقد اني قرات عن ذلك مسبقا وهو جلب handle من filestream بس ذاكرتي مشوشة شوي

ثواني ابحث لك

قمت بالعبث في فئة filestream وبالفعل هناك طريقة لجلب handle للفايل

هذا نوع جديد من الhandle لم اكن اعلم بوجوده انا كان خبري ان الهاندل فقط رقم يشير ل الواجهات والعناصر

ولكن هناك مايسمى ب file handle

انا كتبت الكود لكن طلع تحذير يقولي عليك ان تحول شيئ اولا

بكمل الكود وبرد عليك
