Force File Download XML Problem

[Ken Cox [Microsoft MVP]]

Below is some code I posted yesterday. Does it help?

Imports System.io
Public Class writexmlp
Inherits System.Web.UI.Page


Private Sub Button1_Click _
(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Button1.Click
Dim ds As New DataSet
ds.ReadXml(Server.MapPath("a.xml"))
Dim xmlstream As New MemoryStream
ds.WriteXml(xmlstream)
Response.AppendHeader _
("Content-disposition", _
"attachment; filename=a.xml")
Response.ContentType = "application/download"
Response.BinaryWrite(xmlstream.ToArray())
Response.End()
End Sub
End Class

I have a site which generates a user specific XML document. The user then
selects "Save to PC" which then forces the browser to show the
"save/download" dialog box. The code used is as follows:

Response.AddHeader("Content-Disposition", "attachment; filename=" &
fileName)
Response.ContentType = "text/XML"
Response.WriteFile(fileName)
Response.End()

fileName is an XML document such as myXMLDoc.xml

This works perfectly for later Operating systems such as Windows XP and
Windows 2000 ( SP2 but not where SP1 is installed). The dialog box
automatically recognises the file format as XML and saves the file
correctly.

Earlier Operating Systems fail to recognise the XML format and unless
manually altered, save the file as a gobbly-glock text file.

Is there a work around where I can force earlier systems to save an XML file
as an XML file without the user having to manually enter the save as
filename with the XML extension?

With Thanks,

Thanks Ken.

Older operating systems still just download the file as a "Document".
Windows XP correctly identifies the xml extension.

Your code works as long as the filename and extension is hard coded (such as
a.xml in your example). However, on the actual site the file itself is
dynamically generated as is the filename. For reasons I can't explain, when
the filename is dynamically created the file is downloaded as a "Document".
Once downloaded, if you then add the xml extension it works fine.

I guess the simple answer here is to tell users to ensure that the file is
correctly named after being downloaded.


Thanks,

Peter
