أحاول التواصل مع برنامج تشغيل نظام الملفات الخاص بي. يمكنني بدء تشغيل برنامج التشغيل باستخدام OpenScManager ، وإنشاء خدمة و OpenService ، لكن عندما أحاول استخدام "CreateFile" ، فإنه يقول دائمًا ErrorCode 2 (أعتقد أنه لم يتم العثور على ملف وما إلى ذلك).
هذا هو الكود بأكمله:

Unloading now...
FsFilter unloaded
يعمل التحميل والتفريغ بشكل جيد (تم فحصه مع DebugView). المشكلة هي أن CreateFile يقول دائمًا "-1" / "2". لقد اختبرته مع برامج تشغيل أخرى ولكن لا يزال كما هو. عندما أفتح textfile مع CreateFile ، يعمل بشكل جيد ، لكنني أريد التواصل مع برنامج التشغيل الخاص بي (DeviceIocontrol) ، لذلك أحتاج إلى فتح جهاز التشغيل ...
هل يمكن لأحد أن يساعدني / يعطيني تلميحًا؟ شكرًا!
المحلول
أنا أتساءل كيف فشل السائق في التحميل وحتى الآن "تم تفريغه" ... أيضًا ، لا بد لي من الاستعلام عن هذا ....
Win32Driver driver = new Win32Driver(driverName,@"c:\\FsFilter.sys");
لماذا هو اسم السائق المتشددين ، ليس وحدك ، أنت تستخدم سلسلة "حرفي" لذلك ليست هناك حاجة للهروب من الزلاجة الخلفية ... هل جربتها بهذه الطريقة:
Win32Driver driver = new Win32Driver(driverName, Path.Combine(@"C:\", driverName));
شيء آخر ... عندما يتم إجراء مكالمة عبر "CreateFile" ، فأنت تمر في اسم ملف موجود "fsfilter.sys" للقراءة حتى الآن ، تم تحميله بالفعل ...؟ كان ينبغي أن يكون ذلك \\.\FsFilter مع انخفاض التمديد ... هذه هي الأشياء التي لاحظتها ولديها علامة استفهام حول ...؟
أتمنى أن يساعد هذا ، مع أطيب التحيات ، توم.
نصائح أخرى
نعم ، هذا فعل الخدعة:
fileHandle = createFile (".
شكرا لتوم :)
الآن أحصل على شاشة Bluescreen ، لكن هذه مشكلات سائق يجب أن أعمل عليها. تم فتح السائق الآن بشكل صحيح :)
