I'm trying to generate a text file and make it downloadable for users, I
did look at a standard Response.Write file using headers etc but this made
IE crash. Somebody has since pointed me in the direction of ASHX files,
however I'm still having a few hitches.
I had a look around and managed to find a couple of thread giving examples
for ASHX and I tried to put one together in the following way:
Added an aspx file, renamed it to be an ashx file with the following code:
<%@ WebHandler Language="VB" Class="MailMergeDownloader" %>
Imports System
Imports System.Web
Public Class DownloadHandler
Implements IHttpHandler
Public Sub ProcessRequest(ByVal context As HttpContext) _
Implements IHttpHandler.ProcessRequest
Context.Response.ContentType = "text/text"
Context.Response.AddHeader("content-
disposition", "attachment; filename=Merge2.txt")
Context.Response.WriteFile("C:\Temp\Merge.txt")
End Sub
' Override the IsReusable property.
Public ReadOnly Property IsReusable() As Boolean _
Implements IHttpHandler.IsReusable
Get
Return True
End Get
End Property
End Class
The only way I can get it to work is be calling the ashx file on a page
load event of a blank aspx page by using response.redirect.
The file downloads OK but the web page diplays an Action Cancelled message
in IE. Is there anyway of avoiding this, I have a horrible feeling it is
something simple that I am missing?
Any help would be greatly appreciated!
Thanks
Colin
