Downloading

[Kenneth Windish]

Hi,

This has probably been discussed before, but I have been unable to find
anything on it, except an article written in C or C+, or C# and not in VB.

How can I download a file from my web page to a client?

Thanks in advance.

Ken

Dear kan,

There are many ways to download a web file (remote file). The best way, i
ever invent in dotnet is to do it with webclient object.

This object provides you many methods for download data, you can also
download a file as a data or can also download file using
webclient.DownloadData(URL) method or DownloadFile(URL).

In C# or vb.net you can use this. The other thing, you can also provide
credential for those web location which have some authentication, windows or
whatever.

Hi Kenneth,

In order to download files to a user machine you can use the following code snippet to do so:

Dim FilePath As String = Server.MapPath("abc.txt")
& nbsp;Dim TargetFile As New System.IO.FileInfo(FilePath)

' clear the current output content from the buffer
Response.Clear()
' add the header that specifies the default filename for the Download/
' SaveAs dialog
Response.AddHeader("Content-Disposition", "attachment; filename=" + _
TargetFile.Name)
' add the header that specifies the file size, so that the browser
' can show the download progress
Response.AddHeader("Content-Length", TargetFile.Length.ToString())
' specify that the response is a stream that cannot be read by the
' client and must be downloaded
Response.ContentType = "application/octet-stream"
' send the file stream to the client
Response.WriteFile(TargetFile.FullName)
' stop the execution of this page
Response.End()
