Forcing a file download w/ a button

[Do]

Hi,

My issue is twofold.

1) How do I invoke a "save file" action when a user clicks a button.
In classic ASP, I used to response.redirect to file path. But I want
to keep the user on the same page they clicked "Download" button.

2) How do I force to prompt for a save file when the user clicks the button
rather than try to open and read the file in the browser, which is the
default action.

Thanks,

Do

This may do what you want (here file names for download are listed in a
radio button list)

Dim filepath As String
Dim filename As String
If Me.RadioButtonList1.SelectedIndex <> -1 Then
filename =
Me.RadioButtonList1.Items(Me.RadioButtonList1.SelectedIndex).Text
filepath = Server.MapPath(".") & "\downloads\" & filename
Else
Exit Sub
End If
Response.Clear()
Response.ContentType = "application/octet-stream"
Response.AddHeader("Content-Disposition", _
"attachment; filename=""" & filename & """")
Response.WriteFile(filepath)
