I want to be able to run an ASP.NET application when a file is upload via FTP. I understand how to use the filewatcher class to monitor the directory but I don't know where to put the code so it is always running.
Files will be uploaded once per month for each group of users of the system and the next time the user logs on after the upload I would like the application to reflect the new data. I don't want to check for a new upload when each user logs on because the processing could take a log time.
The uploads are automatic from multiple other computer systems and not done by any user.
The Application is hosted (by GoDaddy) so I don't have full control of the server.
Is there any way to have a process running all the time in the background and if so how? The application is written in VB.net.
In my application i am sending emails of bigger size (> 2.5 Mb). Now till the emails are being sent, the application is in hanged up state (mouse cursor is of busy state).One of my friend suggested to use background worker that "could" display message something like "Please wait...Sending email". I have no idea as to how to use the background worker process. if there is any other quicker/easier alternative,
View 6 RepliesI have Requirement to update the label text as we are processing the code (Long running).
Example:
I have Label and button on aspx page.
On button Click Iam calling the AppCode which is going to do long work for me.
I want to update the label text from the appcode (which should reflect in the page then and there.)
I have tryed to pass the text value to the label but it shows the changed text only after the event for the button click is finished.
I tryed using timer but as soon as i click the button the refreshing stops.
I tryed progress template and UpdateProgress without success. (I know we can update at the start and end of proccess using this)
I dont want to use iframe (I know we can do using iframe)
I have made web service, when it is accessed by remote computer to send me the data using this web service then the following errors shows on the remote computer:-
"Server was unable to process request..A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
I have an asp.net mvc application that spawns a Process as follows:
Process p = new Process();
p.EnableRaisingEvents = true;
p.Exited += new EventHandler(p_Exited);
p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath;
p.StartInfo.WorkingDirectory = dir;
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "pdflatex.exe";
p.StartInfo.LoadUserProfile = true;
p.Start();
p.WaitForExit();
Before going further, I need to know whether, e.g., pdflatex.exe is a managed code or a native code? Edit 1 I need to consider this because: (Hopely I am not wrong...) Each Asp.net application runs in an separate/isolated AppDomain as opposed to a separate/isolated process. A native executable cannot live in an AppDomain.to be continued.. Shortly speaking, I hope my site does not spawn a new process for each request. Because a process is more expensive than an application domain. Edit 2 My asp.net mvc application allows users to submit LaTeX input commands such as $ax^2+bx+c=0$ to be converted to a pdf file rendering an quadratic equation. Behind the scene, this web app will spawn a process executing pdflatex.exe. The job of pdflatex.exe is converting the LaTeX input commands to pdf document.
Currently we are developing an ASMX, ASP 2.0, IIS 7 web service that does some calculations (and return a dynamically generated document) and will take approx. 60 seconds to run.Since whe have a big machine with multiple cores and lots of RAM, I expected that IIS tries its best to route the requests that arrive in its requests queue to all available threads of the app pool's thread pool.But we experience quiet the opposite:When we issue requests to the ASMX web service URL from multiple different clients, the IIS seems to serially process these requests. I.e. request 1 arrives, is being processed, then request 2 is being processed, then request 3, etc

The exception was coming out of the Web Service itself. There were some global variables not being initialized directly through the .asmx call that were being initialized by the application itself.
Some simple checks on variables within the Web Service and setting what needs to be set have fixed up the issue.

View 1 RepliesI have created a web service that interacts with my DAL. It has the usual kind of methods, create, retrieve, update and delete. I have published this web service to our live Windows Server and I can see the web serice URL. The web service works on a few method calls but does not work specifically for one object. I am getting the following error: Fault Exception was unhandled by user code. "Server was unable to process request. ---> Data is Null. This method or property cannot be called on Null values."
To summarise: Web service is live, I can see it in my browser. Some method calls work. One specific one does not. I have verified that the method works (it is just calling a SQL stored proc that does return data).
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.
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?
I'm working on an ASP.net app I'm trying to execute a process remotely , using System.Diagnostics.Process class here's my code:
ProcessStartInfo startInfo = new ProcessStartInfo(@"C:TestCommand.exe");
startInfo.Domain = "myDomain";
startInfo.UserName = "MyUserName";
SecureString sec = new SecureString();
foreach (char item in "MyPassword")
{
sec.AppendChar(item);
}
sec.MakeReadOnly();
startInfo.Password = sec;
startInfo.UseShellExecute = false;
Process.Start(startInfo);
I keep receiving an exception with the message "Logon failure: unknown user name or bad password". Im absolutelly sure that i'm submiting my correct username/pwd
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?
