downloading file get empty from one server.

[Guest]

Hi,
On one of my server, downloading file by clicking a button give empt
file. On the other servers work perfectly. Is any idea ? What should be
change in IIS Metabase setting?
After click the button on an aspx page, IE prompts the users whether they
want to open, save or cancel the download with correct name. No matter click
open or save, it started download and transfered 0 byte. I checked the server
side it did created the file with correct contents. The code is same as those
many posted here.
Thanks in advance.

What about posting some code ...

Code runs good on other servers. But here is the code:

Response.AddHeader("Content-Type", "application/csv")
Response.AddHeader("Content-Disposition",
"attachment;filename=" + fileName + ";")

Dim Fs As FileStream = New FileStream(Server.MapPath("~/" &
fileName), FileMode.Open)
Dim FileSize As Long = Fs.Length
Dim bBuffer() As Byte = New Byte(FileSize) {}
Fs.Read(bBuffer, 0, Convert.ToInt32(FileSize))
Fs.Close()

Response.BinaryWrite(bBuffer)
Response.Flush()
Response.Close()

Thanks,
Frank

Maybe here is not the correct place to post this question. Any suggestion
that which newsgroup I should put ?

I feel kinda weird about the combination of csv and binary...

Here's code from something I wrote a few weeks ago... it's .NET 2.0 and
C#, so you will have to play, but it works great.

string fullpath = @"c:\windows\temp\" + excelFileName;

using (FileStream fs = new FileStream(fullpath,
FileMode.CreateNew, FileAccess.Write, FileShare.Write)) {
fs.Write(file, 0, file.Length);
}

// FileInfo fileInfo = new FileInfo(fullpath);
Response.Buffer = true;
Response.Clear( );
Response.ClearContent( );
Response.ClearHeaders( );

Response.AddHeader("Content-Disposition", "attachment;
filename=" + "AutoGeneratedReport.xls");
Response.AddHeader("Content-Length", file.Length.ToString(
));
Response.ContentType = "application/vnd.ms-excel";
Response.WriteFile(fullpath);
Response.Flush( );
