سلام:اشتباه:
لطفا کمک کنید نیاز فوری دارم:عصبانی++:
من قطعه کدی به نام Ipn handler نوشته ام که در صورتی که فرد با سیستم paypal خرید کرد، paypal باید این کد را فراخوانی کند ، تا برنامه من چک کند که درست فراخوانی شده یا نه و در صورتی که درست یا نادرست باشد برای کاربر یک ایمیل می فرستد و وضعیت خرید را برای او ایمیل می کند ولی این کار صورت نمی گیرد. در واقع صفحه ipp.aspx من که توسط پارامتر "<input name=\"¬ify_url\" type=\"hidden\" value=\"http://www.test.ir/ipp.aspx\">"به paypal پاس داده می شود:متفکر:
و صفحه ی ipp.aspx من به صورت زیر می باشد:
