MVC :: Cannot Receive / Process POST Data Successfully

Jun 5, 2010

I have the following ViewModel:

[Code]....

This goes into a view like this:

[Code]....

Which as a result generates this:

[Code]....

Now, I'm trying to receive this data in a method so I can update stuff, like this:

[Code]....

But the above is not working. I've tried using [Bind(Prefix="user")] with no success. Before using this setup, I had all the user's properties directly in the ViewModel and the above method worked like charm.

What can I do to be able to process my POST request? I do not want to change my ViewData structure. I presume the answer to the question is not to difficult and lies only in adding something or changing some properties.

C# - Web Service Receive HTTP POST Request (500) Internal Server Error?

Nov 15, 2010

I am currently writing a C# web service which has several methods, one of which has to receive HTTP POST requests. The first thing i have done is alter the web.config file in the web service project as below.

[code]....

But when i run this i get "The remote server returned an error: (500) Internal Server Error". If i remove the parameter, by removing the stringbuilder and byte code, as well as having no parameter in the web service, it works. So it is obviously a problem with the parameters. I actually want to send more data, and was using a string[] parameter in the web service, but this also failed.

DataSource Controls :: "post-process" A Column Before Bound Controls See The Data?

Apr 8, 2010

Here is what I need to do:

- SELECT from a table

- Do something to the data after the SELECT but before anything else

- let the controls that are bound to my data see it.

I've already got working code to Undo my something when Updating or Inserting

These are the requirements:

- use a plain-jane SqlDataSource to do the SELECT

- doing the something has to take place at the SqlDataSource, not in events of the databound controls.

From the MS site the SqlDataSource.Selected event is where I should do "post-processing" however I can't find any examples of doing so.

How To Call And Receive URL Data

Jan 28, 2011

In asp.net (or vb) I must to call a page that only autenticates a user, returning the user data if the logon succed. This way, I would like to implement the sequence:

A blank page (mine) request the autenticator page (3rd part) automatically on load; The user logs in the autenticator page; My page reads the autenticator page results and do the actions.

I'm a very begginer in asp.net, and I'm using vb.net in the environment for coding the page "onload" event. I'm trying to use the "redirect('url')" method to call the autenticator's page, but in this way, obviously, I can't receive the result. How can I implement this sequence?

How To Receive Data From Database And In A While Loop

Oct 15, 2010

i want to receive some data from my database and in a while loop. i use this code in the while loop

Code:
Dim sqlda As New SqlDataAdapter()
sqlda.SelectCommand = New SqlCommand()
sqlda.SelectCommand.Connection = con
sqlda.SelectCommand.Parameters.Add(paramar(0))
sqlda.SelectCommand.CommandText = "select images,creationdate,dimosieyseis from t_accounts where UserName=@un"
Dim ds As New DataSet()
sqlda.Fill(ds)

if i open and close the connection it becomes slow. if i use a general con and not open and close it then i receive an error

"There is already an open DataReader associated with this Command which must be closed first. "

then i tried to resolve this error with

MultipleActiveResultSets=True that resolves the problem but it is not faster because i think it does the open and close of the connection automatically

C# - How To Find The Elapsed Time Between Send And Receive Data

Feb 28, 2010

I am using the System.Timers.Timer class. And I enable when I send a message and disable when I receive the message. How do I calculate how much time has elapsed. I have set the interval as 1 sec

Basically I retransmit data after 1000 sec again if I do not recive an ACK. I retransmit 5 times max until I get a Ack. If I receive and something before 150ms then I stop retrnsmission.

Here's the code:

timer1.interval = 1000;
port.Write(data)
timer1.enabled = true;

event handler for the received data.

Configuration :: Process.start (System.Diagnostics.Process) - Execute A Batch File

Sep 7, 2010

I've written a aspx.net(C#) page that after the user has done what they do on the page they hit a Submit button. The Submit button

1) takes the work the users was producing on the page and writes it to a file.
2) attempts to execute a batch file.

The call to the batch file is executed via:

protected void Execute123EDI()
{
try
{
string File = @"c:80sAdminSendV80s.bat";
lblCancelled.Text = lblCancelled.Text + File;
Process proc = new System.Diagnostics.Process();
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.LoadUserProfile = false;
proc.StartInfo.UserName = "administrator";
proc.StartInfo.RedirectStandardOutput = true;
System.Security.SecureString secPass = new System.Security.SecureString();
string paswd = "123abc";
for (int i = 0; i < paswd.Length; i++)
{
secPass.AppendChar(paswd[i]);
}
proc.StartInfo.Password = secPass;
proc.StartInfo.FileName = File;
proc.Start();
FileStream fs = new FileStream(@"c:80sAdminSendV80sOutput.log", FileMode.Append);
StreamWriter sw = new StreamWriter(fs);
sw.Write(proc.StandardOutput.ReadToEnd());
proc.WaitForExit();
sw.Close();
proc.Close();
}
catch(Exception ex)
{
lblDebug.Text = lblDebug.Text + ex.Message + "<br/>";
}

If I watch the processes tab in Task Manager on the web server I see "cmd.exe" under the context of 'administrator' but it just hangs. For test purposes c:SendV80s.bat: copy c: oot.ini c:zzz.txt

If I logon onto the webserver's console and execute SendV80s.bat it works and exits without issue. But when I execute the same batch file via the Submit button it gets stuck executing in Task Manager/Process. I believe this has something to do with the fact that cmd is not running in a full environment/desktop context. I just noticed this on the actual console of the webserver (not in my RDP console but console 0 instead)

A pop-up box stating: CMD.exe Application error The application failed to initialize properly (0xc0000142). Click OK to terminate the application. And when I click on the OK button my ASPX page's WaitForExit is satisfied and the continues processing normally.

Long Running HTTP Process - How To Put In Separate Process

Jul 21, 2010

I know that similar questions have been asked all over the place, but I'm having trouble finding one that relates directly to what I'm after.

I have a website where a user uploads a data file, then that file is transformed and imported into SQL. The file could be up to 50mb in size, and some times this process can take 30 minutes or sometimes even longer.

I realise I need to palm off the actual work to another process, and poll that process on the web page. I'm wondering what the best approach would be though? Being a web developer by trade, I'm finding all this new Windows Service stuff a bit confusing, and I just wanted somewhere to start.

So:

Can I do / should I being doing this with a windows service? if so, how?

Should I use WCF? If this runs under IIS, will I have problems with aspnet_wp.exe recycling and timing out my process?

clarifications

The data is imported into sql, there's no file distribution taking place.

If there is a failure, it absolutely MUST be reported to the user. The web page will poll every, lets say, 5 seconds, from the time the async task begins, to get the 'status' of the import. Once it's finished another response will tell the page to stop polling for status updates.

queries on final decision

ok, so as I thought, it seems that a windows service is the best idea. So as to HOW to get it to work, it seems the 'put the file there and wait for the service to pick it up' idea is the generally accepted way, is there a way I can start a process run by the service, without it having to constantly be checking a database table / folder? As I said earlier, I don't have any experience with Windows Services - I wondered if I put a public method in the service, can I call it somehow?

Web Forms :: The Process Cannot Access The File 'c: Empmy.pdf' Because It Is Being Used By Another Process?

Apr 3, 2010

I've developed a popup email .aspx used on our intranet based web app that is auto generated with .pdf's attached. I'm developing with VS 2008 ASP.Net 3.5 C# and System.Net.Mail.MailMessage. I can create and send the email with no issues. The problem is with any attempt to open or delete the attachments I get the above error. The .pdf's a copied with the following code:

FileStream fsr = new FileStream(inFilename, FileMode.Open, FileAccess.Read, FileShare.Read);
BinaryReader reader = new BinaryReader(fsr);
byte[] bytes = new byte[fsr.Length];
reader.Read(bytes, 0, bytes.Length);
FileStream fsw = new FileStream(outFileName, FileMode.Create, FileAccess.Write, FileShare.Write);
BinaryWriter writer = new BinaryWriter(fsw);
writer.Write(bytes, 0, bytes.Length);
// clean up
writer.Flush();
writer.Close();
writer = null;
fsw.Close();
fsw.Dispose();
fsw = null;
reader.Close();
reader = null;
fsr.Close();
fsr.Dispose();
fsr = null;
Later after sending the email I:
mailMessage.Dispose();
mailMessage = null;
foreach (string fileName in attachments)
{
if (File.Exists(fileName))
File.Delete(fileName);
}

The error occurs at: the File.Delete(fileName);

how I can delete or reopen these files after sending the email?

How To Recognize Whether The Process Is The IIS Worker Process From Within A .NET Code

Dec 25, 2010

Dear ladies and sirs.

I have a .NET infra code running both within the IIS worker process and within a desktop client app. How can the .NET code determine whether it is running within an IIS worker process?

I know that I could check the name of the process (w3wp.exe, for instance), but I would like a more robust approach. I wish to make a side note. This is not a production need. I need this information to enable certain scenarios useful during the development and testing phase. Specifically to ease the testing of secure vs non secure configurations.

How do I: Ensure that only a single process is running at a time (i.e. if I refresh the browser, I don't want to start the process a second time)Track progress - there are 4 points of the process (at 25%, 50%, 75%, 100%) that I want to track, and when each part completes, I want to update the progress bar. I have a status object for the running process, but the question is how to update the progress bar automatically? Do I need to use threads to achieve the above two?
