Hi experts,
I need a linkbutton/button to download the files which my clients have uploaded.
Below is my upload method and it works.
However, it's not working for downloading of file (in another asp)
May I know how can I do that?
The files format that are uploaded are not consistent. Usually it's excel, word or pdf format.
Please help. Thanks!

Not 100% sure what you are trying to do? Upload or Download a file. For download you need to replace the response stream with the file. This link is pretty good for downloading:

Use lots of try catch blocks...

Hi. Thanks for your reply.
I'm trying to download files. By the way, I'm using C# so doesn't really quite understand the VB code.
I tried this .
protected void btnLink_OnClientClick(object sender, EventArgs e)
{
String pid = Convert.ToString(Session["pid"]);
String file = System.IO.Path.GetFileName(Server.MapPath("Docs/" + pid + "/EP/"));
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + file);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.WriteFile(file);
Response.End();
}
But it doesn't work .
Error msg : Access to the path 'C:\Documents and Settings\[machineName]\My Documents\[projectName]' is denied.
Is it because I upload at my documents?
What should I do? Please help. Thanks

set your permissions to allow access to my documents.
saying that i remember not being allowed access to a servers My Documents folder even with permissions set.
use another file location i.e.
c:\WEB APP FILES\

Thanks for your reply.
Nope, I realised that variable ''file'' is empty.
But I thought that's the way to get the filename and extension in a directory path?
May I know how to do that?

well theres no file your just referencing the directory "Docs/##/EP/" ? try passing a filename through ?
also 'file.Length.ToString());' will not return the files size as its just a string variable you will need to do a
then use the 'FileInBytes' attribute to show the file length
also 'file.Length.ToString());' will not return the files size as its just a string variable you will need to do a
FileInfo finfo = new FileInfo(Server.MapPath(MyFile)); long FileInBytes = finfo.Length;
then use the 'FileInBytes' attribute to show the file length

after re-reading you say you want them to download THE files.
the only way to do a batch download is either open a window for each file, create a zip file on the fly with all files inside, or have aprompt for them to download file sone at a time by selecting them

Thanks for your reply.
You're fast.
Actually the thing is I wouldn't know what are the files that are being uploaded in the first place.

okay, I pass a filename already. It works.
Now I have to solve the problem.
To download the files which is "unknown" to my clients' users.

I got it . I used another method found online.
Just that it opened the application immediately without the filedialog box.
DirectoryInfo diSource = new DirectoryInfo(Server.MapPath("Docs/" + pid + "/EP/"));
string ExactFilename = string.Empty;
foreach (FileInfo file in diSource.GetFiles(@"*.*"))
{
ExactFilename = file.FullName;
}
System.Diagnostics.Process.Start(ExactFilename);Just that it opened the application immediately without the filedialog box.
