hi mukesh. well what ive done is that first u'll need to add the <input> tage in the page. E.g <input id="txtUpload" runat="server">. by having this tag, it will enable u to browse for specific file in ur comp to be upload. after that to upload the file all u have to do is using this code : txtUpload.PostedFile.SaveAs(<path where u want to upload the file>)
Make sure to import the System.IO namespace before using this upload method. For example if u want to save it in the server u can use the server.mappath method. The code :
Dim sPath as String
sPath = Server.MapPath(".")
will store the selected file in the same folder where ur page is. Hope this will help u.
