سوال:در مورد WINCE
با عرض سلام و خسته نباشید
من یه برنامه رو برد اجرا میکنم ولی پورتو باز نمی کنه و ارور میده
خواهشمندم که کمکم کنید
چند بار کدها رو خوندم و چند جاشو اصلاح کردم ولی بازم کار نمیکنه
اگه نگاهی به کد بندازید و اشکالشو بهم بگین ممنون میشم
من کل کد رو نوشتم ولی مشکلم توی تابع
createfile
فک میکنم باشه
