no myfile is the ashx file,
The address to the csv file is in the code that goes in the ashx file, line 3 below
but instead of creating the file in the first place why not just send emails straight from the web page?
Or create the link as I showed to the ASHX page. put the code I supplied in it, and it will work, I tested it, it works.
I prefer to use AJAX. My interface is very rich with information about customers and so on. I had the idea that writing a letter to a contact would be easy:
- first i thought using word on the server. this does work but is a violation with the licenseagreement and not stable since office is not a multiuser product.
- my second thougth was juist generate the merge fields in a list, let the user open word and merge this togeter to get the letter. This is not the best solution, but fair enough
- your suggested that I could add :
<a href="myfile.ashx">click here</a>
i presume myfile is the file i have created. But as you suggested a button would also do the trick: the trick is:
context.Response.ContentType = "text/csv"
context.Response.AddHeader("content-disposition", "attachment;filename=yourdoc.csv")
Dim csvFile As IO.FileInfo = New IO.FileInfo(context.Server.MapPath("\yourfolder\yourfile.csv"))
Dim sr As IO.StreamReader = csvFile .OpenText
context.Response.Write(sr.ReadToEnd)
So what I have in mind is the following idea
I add a button outside the updatepanel (next to the templates the user can choose from)
after picking 1, no postback will occur, but on the clientside I will make the button vissible. The text would be GET merge file
I create the merge file on the server and will and with your lines.
I hope it will work. But if you have some better ideas, i would appreciate it
thanx

"ThatsIT.net.au" <me@work> schreef in bericht Better to not use the Ajax.
if you cant give a link to the file, then its not going to work no matter what.
you simply have to allow the user to navagate to it, it does not have to be the same button
all it needs is
<a href="myfile.ashx">click here</a>
when adding these line in an non ajax enviroment it gives the popup dialog to open or save the file. Using it on a button within an updatepanel I get:
sys.webforms.pagerequestmanagerparsererrorexception: the message received from the server could noy be parsed. Common causes for this error are when the rersponse is modified bij calls response.write(), response filters, httpmodules or server trace is enabled. etc
so how about this challenge?
I do not use the ashx file.
any ideas?
thanx

have not done it, but I still do not get it where the ashx get involved. The button procedure creates the doc file on the server and then what?
thanx

replace previous 3 lines of code with
context.Response.ContentType = "text/csv"
context.Response.AddHeader("content-disposition", "attachment;filename=yourdoc.csv")
Dim csvFile As IO.FileInfo = New IO.FileInfo(context.Server.MapPath("\yourfolder\yourfile.csv"))
Dim sr As IO.StreamReader = csvFile .OpenText
context.Response.Write(sr.ReadToEnd)
sorry I did not get straight back as promised I had a long phone call
will give you the code in a minute or 2
what do you mean navigating to the ashx file. The webpage shows information about customer data, with textboxes, dropdownlist, buttons and so on. Pressing on the "sendletter button" creates a csv or text file whatever. It is this file I want to promt to the user so he can save it. After opening word and choosing the correct template this file will be used in the merge.
Other questions are in your message
Thanx
"ThatsIT.net.au" <me@work> schreef in bericht I guess we better make sure were reading from the same page
a few quick questions, ill be watching for your answers so we can move quick
You already have code that creates a txt file? YES
you have all ready saved it on the server? YES
if so what name did you give it, did you save it as blah.csv ? YES
try navigating to the ashx file and tell me what happens
I'm sorry. I do use visual studio and I have added your file. But it is a ASP appllication which after clicking by the users will end in creating the txt file. This file is forst stored on the server but then. What should I do next. I still see no place where and how to use the ashx file
thanx
"ThatsIT.net.au" <me@work> schreef in bericht Are you using visual studio?
if so add a ashx page, called generic handler in the menu
then all you need is to add 3 lines, 5the last line will write you data. ashx page is much like a aspx page but dose not include a load of stuff needed for a web page. its used for displaying other file types such as a csv file
context.Response.ContentType = "text/csv"
context.Response.AddHeader("content-disposition", "attachment;filename=yourdoc.csv")
context.Response.Write("Hello World!")
I do not know what you mean.
Your suggestion is that I should add a file to my solution (ashx): I did this and then?
<%@ WebHandler Language="VB" Class="word" %>
Imports System
Imports System.Web
Public Class word : Implements IHttpHandler
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
context.Response.ContentType = "text/csv"
context.Response.AddHeader("content-disposition", "attachment;filename=yourdoc.csv")
context.Response.Write("Hello World!")
End Sub
Public ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
Get
Return False
End Get
End Property
End Class
What should I do with it?
thanx
"ThatsIT.net.au" <me@work> schreef in bericht change
context.Response.ContentType = "application/msword"
context.Response.AddHeader("content-disposition", attachment;filename=yourdoc.doc")
to
context.Response.ContentType = "text/csv"
context.Response.AddHeader("content-disposition", attachment;filename=yourdoc.csv")
