Web Forms :: Getting Data And Sending It In A CSV File To User
Oct 21, 2010
I'm creating an ASP.NET application that needs to get data from database (time consuming) and show some indication (e.g. gif animation) that the application is doing something. After that the data should be send to user that the user can save or open the CSV file.
I'm able to do this with two button click's. One for getting the data from the database in codebehind and using javascript to show the gif animation for user in the meanwhile. Second to use the esponse.write(myData) and response.end() to send the data for user to save in CSV file.
The problem is that I need to do this with one button click. If I combine the code to one button click handler the data is sent correctly but the gif animation is not hidden because the page is not updated. How to do this correctly with one button click?

i am trying to send a email with the info supplied from my form. i have got the code from a book im going through ( asp.net 3.5 in c# and vb ). First here is the code behind from the submit button:
Protected Sub btn_submit_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim fileName As String = Server.MapPath("~/App_Data/ContactForm.txt")
Dim mailBody As String = System.IO.File.ReadAllText(fileName)
mailBody = mailBody.Replace("##Name##", tb_firstName.Text)
mailBody = mailBody.Replace("##Surname##", tb_surname.Text)
mailBody = mailBody.Replace("##eMail##", tb_eMail.Text)
mailBody = mailBody.Replace("##Subject##", tb_subject.Text)
mailBody = mailBody.Replace("##Description##", tb_description.Text)
Dim myMessage As MailMessage = New MailMessage()
myMessage.Subject = "##Subject##"
myMessage.Body = mailBody
myMessage.From = New MailAddress("jay@jwwebdesign.net", "##Name##")
myMessage.To.Add(New MailAddress("jay@jwwebdesign.net", "Me"))
Dim mySmtpClient As SmtpClient = New SmtpClient()
mySmtpClient.Send(myMessage)
End Sub
and here is the code from the web.config:
<system.net>
<mailSettings>
<smtp deliveryMethod ="Network" from ="Jay <[URL]>">
<network host ="smtp.jwwebdesign.net" />
</smtp>
</mailSettings>
</system.net>
when in debug mode it points the error to being:

On the first hit, and only the first hit, to my page having [ALLOW users="*"] in the web.config, the user is redirected to the LoginUrl, but on all subsequent visits to the page, the user IS allowed access. The user shoud ALWAYS be allowed access to this page. I suspect it is a configuration problem, so here are snippets of my web.config...

I want to have a web service which creates CSV data and writes it to a plain txt file on the client side. I was thinking of something like a GetData() method which returns a StringBuilder which contains the file content. The client of the service writes that into a file on the clients machine. Everything transfered needs to be secured, the web service runs together with a web app which is hosted on a https server...is calling the service secured then, too?

I have this web application (LAN) that sends an email when users registers to one of our events.
The code is pretty straightforward:

The application sends the email without problems. The issue is that somehow a third person is enlisted in the cc, and receives a copy of the email!. What could be the problem? The smtp? IIS?

I've been pulling my hair out about this for ages. I have a WebService which sends a zip file to the browser. This works; when I test the WebService and 'invoke' the method through it directly, the zip file is downloaded to the browser correctly.
The problem arises when I use jQuery to send an AJAX request to the WebService - the zip file is downloaded to the response, but it stays in the response and doesn't download as a file.
Here is my code:
[Code]....
Now this works since the file downloads when I use the 'invoke' function when navigating directly to the service.
Here is my jQuery AJAX request...
[Code]....
I added the code in 'beforeSend' so that the request states explicitly what type of response the browser should expect.
I've been using Firebug to monitor the request/response headers and can't see anything wrong with them (except when I look at the content of the response, it's full of binary data AND its the same size as the file I'm sending.
I just attempted to upload screen-dumps of the request/response headers and the content of the reponse but I don't have enough reputation points to do this yet :-(
The Response is the same size of the Zip file so I'm assuming its being sent back to the browser, but the browser doesn't know what to do with it.
Tested in IE, FF & Chrome and the results are consistent.

In classic ASP if you wanted to send a user to a specific page you would send/create a URL like :
posts.asp?id=24 ...the querystring indicating the post.
Well, in asp.net using a DetailsView control bound to a dataset, how do I do the same thing? In the address bar, all i see is posts.aspx when I'm paging through the records, no querystring part. How do I send a user to posts.aspx?id=24 when its a detailsview control on the page.
Note: I'm interested in sending a user to a specific postid not a specific index in the dataset.

Is it possible to control the behaviour of ASP.NET when the Session has expired? It seems that the default behaviour is sending the user to the website root. The desired effect would be to send the user to a custom "Session Expired" page.To clarify, it's the SessionState that's expiring (set the timeout to 1 minute to quickly test it):
<sessionState mode="InProc" timeout="1"></sessionState>
The authentication cookie timeout is way higher, to avoid any mix-up:
<authentication mode="Forms">
<forms loginUrl="SessionExpired.aspx" slidingExpiration="true" name=".ttpASPXAUTH" timeout="58" protection="All"></forms>
</authentication>

I am developing an application that manages a photo contest. In that application, I use an AsyncFileUpload control for the user selected photo. The server-side UploadedComplete does basic validation, and scales/clip the image as necessary.
The problem is, when i click on the submit button on the page, the content of the AsyncFileUpload gets sent with the other user-submitted data, so the user gets to wait twice as long to get a response from the server (I'm expecting photos that are between 3 and 7 Mb big, which takes a minute or two to upload).
My form looks like that:
<%-- ... snip - all other fields ... -->
<div style="margin-top: 20px; margin-bottom: 5px;">
<span class="texteB"><b>Upload a photo</b></span><br />
Browse your computer to find a photo.</div>

I've been having a difficult time with this. I have an asp.net page. The user hits the "Run" button and I have code IN AN ASSEMBLY, not in the APP_CODE folder that is called and runs a long process that moves product info from a file into the database. While the user waits, I would like them to see status updates like what product the import process in on and status info. I'm assuming I'd break off into another thread and use Ajax but I have no idea how to do this.

after i can copy my file to another folder i realised that if this webapplication is used by multiple users at once, then some users are going to get locked out because each one is trying to copy those files.
so how do i tell the user thats trying to use a file to wait untill the file is available.
StreamWriter WriterTotxt = new StreamWriter("date.txt", false);
DateTime LastAccess = File.GetLastWriteTime("path.dbf");
WriterTotxt.Write(LastAccess);
WriterTotxt.Flush();
WriterTotxt.Close();
string ReadTextFile = File.ReadAllText(txtFile);
DateTime test = Convert.ToDateTime(ReadTextFile);
if (File.GetLastWriteTime(LatestUpdatedTime).CompareTo(test) > 0)
{
File.Copy(Path.Combine(sourcefile, fName), Path.Combine(destinationfile, fName), true);
