حال با دستورات زیر میتوانی فایل رو آپلود کنی
Dim FileInServerPath As String = ' Masiri ke mikhay file Upload beshe dar site ba name file
Dim ftp As New Utilities.FTP.FTPclient(Hostname,User name, Password)' "www.bbbbb.nl", "username", "password)
ftp.Upload(Filename, FileInServerPath)
در ضمن این کلاسهای توابعی برای دانلود و کپی و غیره هم داره که میتوانید استفاده کنید.
البته منهم این کلاس رو از یه جایی دانلود کردم و نوشته خودم نیست اما در 3 تا پروژه بکارش بردم عالی جواب میده
سلام
ممنونم
کلاس رو کپی کردم
فقط کد آپلود رو که گذاشتی رو که کپی میکنم مثلا توی button ارور داره ؟
http://s1.picofile.com/file/7281221498/bb.jpg
با تشکر
ببخشید اشتباه از من بود
درست شد
ممنون
فقط یه چیزی :
fileserverpath رو باید چی بزارم؟
یه توضح هم بهم میدید:
مثلا من فایلی رو بخوام تو
www.picofile.com آپلود کنم
چه طور باید اینجا دستورات رو تغییر بدم ؟
ممنون از راهنماییتون
سلامنقل قول:
نوشته شده توسط mvb_mehran
ببینید مسیری که میخواهید فایل رو درش آپلو کنید رو باید روی هاست بلد باشید. مثلا من میخوام فایل test.txt رو در فولدر facturen در ریشه سایت www.boroewsk.nl کپی کنم برای سرور من متغییر fileserverpath میشه
Dim FileInServerPath As String = "/borowesk.nl/wwwroot/facturen/" & test.txt
مسیر ریشه سرورتون رو پیدا کنید و سپس مسیردهی کنید
برای آپلود فایل تنها Hostname لازم نیست بلکه باید User name , Password هم رو وارد کنید تا اجازه آپلود بهت بده
دستور Dim ftp As New Utilities.FTP.FTPclient سه متغییر لازم دارد اولی نام هاست دومی یوزر نام و سومی رمز Ftp
خیلی خیلی ممنون
درست شد
فایل آپلود شد.
درود , من هم عضو سایت www.picofile.com هستم مگه این سایت اجازه اپلود فایل به صورت FTP رو میده اگه میده باید مسیر رو چی بنویسیم ؟؟؟؟؟
میشه راهنمایی کنی یا کد بزاری من هم یاد بگیرم ؟ ممنوننقل قول:
فایل آپلود شد.
سلام
متاسفانه picofile نشد!
من رو 4shared آپلود کردم.
خوب عزیز روی 4shared چجوری کردی؟منم عضو هستم. ولی چجوری
ببخشید با این کد نمیشه برای اپلود استفاده کرد
My.Computer.Network.UploadFile()
چرا برا من کار نمیده. میشه پروژه های دات نت رو برامون بزارید
