I am running huge time taking background process using a thread. Now Is there any way to show a javascript message whenever the background process completes.
I am using a user control to run the background process. How will I fire the javascript whenever the background process is complete which is unknown.

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 code to copy some files. and then, how I can to show the message of process copy. I think in command prompt (cmd) we can do that with piping to file(txt file). how I can do that.
View 5 RepliesI have a web form used for importing data from a CSV file. It contains a result panel and a result label, which either show a success message or an error message after the import process. Let me say here I know the page should not be doing the import, but this is legacy code and the client expects only small changes.
My problem is that the result message (label) retains it's previous content and visibility during the next import process, because clearing it during Page_Load or at the beginning of the import method only has effect when the import method is complete and thus the postback is complete.
At the moment, the only solution I can see is to move the import code into a separate class (as it should be), call the import method asynchronously, clear the result message, and thne set then result message when the complete or error callback from the import process is called.
How to show confirmation message after the process of saving or inserting a record to Database?
View 3 RepliesI have seen this for a long time, and finally decided to put the question up here. I have some applications that I need to maintain that were written in Delphi 2007 for .NET (ASP.NET 2.0). Normally, the first time I run the application (using IIS) I get the classic "Unable to start debugging on the web server. Unable to attach to ASP.NET worker process" message. I simply press F9 (run) again, and it runs. Sometimes I have to try running several times before it will actually run. I am running Windows 7 64-bit (and have seen the same effect on Vista 64-bit). I do have IIS configured for ASP.NET, and I do have the following code in my Web.config file.
<system.webServer>
<modules>
<add name="DbgConnect" type="Borland.DbkAsp.DbkConnModule,Borland.dbkasp,Version=10.5.0.0,
Culture=neutral, PublicKeyToken=b0524c541232aae7" preCondition="managedHandler" />
</modules>
<validation validateIntegratedModeConfiguration="false" />
</system.webServer>
The point is that I eventually can run the application in the debugger, sometimes even on the first try. Many times when I get the failure it happens about 15 seconds or so after I press Run, sometimes even after I've hit a page or two (or three) of the Web app. And, yes, when Delphi gets into this mode, I can simply run without debugging, and all is fine (unless I really want to debug). And, I can just keep on trying to run in the debugger and eventually it will just work.
It appears that Delphi's .NET debugger is somehow getting the idea that the application cannot run, and then gives up and stops the process (which as I've mentioned is sometimes clearly running). I know of other developers who have also seen this behavior. My question is, does anyone know how to stop this annoying behavior?
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:

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?
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.
When I hit the run button (in my Default.aspx), a process starts (this process contacts a webservice to get some files, etc). 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?
View 1 RepliesMy code is that I want to create a log file and log it upon a new user browsing the site. However, what i did was I put in a 6 second delay and then used another browser to access the page. And it threw an Exception saying it is being used by another process which is true. So how come I set it so that, if IT is being used by another process, WAIT and retry every 500 milliseconds until it becomes free/available?
here's the code:
protected void Page_Load(object sender, EventArgs e)
{if (!IsPostBack) // if this is the first time page loads, set k to 1

I am having the text file which is used to track all the ip address which is available in the network and replace the content from"Reply from 172.29.116.3: bytes=32 time=1ms TTL=255" to 172.29.116.3.
For this task i am having 2 functions 1.runCMD() Function is used to create a file which ping all the ip address between 3 to 254 ("Reply from 172.29.116.3: bytes=32 time=1ms TTL=255").
2.Another function textFileReplace() which is used to replace the text from "Reply from 172.29.116.3: bytes=32 time=1ms TTL=255" to 172.29.116.3.
This process will continue every 30 minutes..
But i am having the error while accessing the function textFileReplace() as The process cannot access the file 'C:inetpub' because it is being used by another process.
I have a stored procedure which fetches data after joining 8-9 tables and inserts that into a temp table. It was running fine till now, but now when the amount of data fetched have exceeded 20000, the SP is breaking. I have debugged the sp and found that this main query is failing after returning arround 15000-16000 records.
The error message says Transaction (Process ID) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. I know what is deadlock, but when i checked with SP_LOCK stored proc i only found that my process is running on database only. So how is this getting deadlocked when there are no other processes running simultaneously on server.
When I delete all files from the directory path. then it will give me this error The process cannot access the file because it is being used by another process. How to solve this?

I am getting binary data from a SQL Server database field and am creating a document locally in a directory my application has permissions. However I am still getting the error specified in the title. I have tried numerous suggestions posted on the web including those suggested in previous posts on Stackoverflow. I have also used ProcessExplorer > Find Handle to locate the lock and it returns nothing as if the file is not locked.
I am using the code below to save the file to the file system and I then try to copy this file to a new location later in the application process within another method. It is this copy method that takes the path of the newly created file that throws the exception.
The file itself is created with its content and i can open it through Windows Explorer without any problems.
Am I missing something completely obvious? Am I creating the file correctly from the database?
// Get file from DB
FileStream fs = new FileStream(
"C:myTempDirectorymyFile.doc", FileMode.OpenOrCreate, FileAccess.Write);
BinaryWriter br = new BinaryWriter(fs);
br.Write("BinaryDataFromDB");
fs.Flush();
fs.Close();
fs.Dispose();
// Copy file
File.Copy(sourceFileName, destinationFilename, true);
Iam getting the above said error while Iam copying a file of relativelly Heavy say 130 MB.Below is the code which is giving the error.

I am using a AsyncUpload(telerik), i am in a point where i am supposed to save the File to a certain Folder. First I check if the directory exist
Code:
Dim baseDire As String = Server.MapPath("~/MyFILES/")
If IO.Directory.Exists(baseDire & Request("Req_ID").ToString()) = False Then
IO.Directory.CreateDirectory(baseDire & Request("Req_ID").ToString())
End If
Because i am doing multiple Upload , i will have to loop through the items of the Upload control and save to a folder.
Code:
For Each file As UploadedFile In UploadPropDoc.UploadedFiles
Dim bytes(file.ContentLength - 1) As Byte
file.InputStream.Read(bytes, 0, file.ContentLength)
'Save the File to the disk
file.SaveAs(baseDire + file.GetName())
Next
Now when ever i debug this , when it comes to this line
Code:
file.SaveAs(baseDire + file.GetName())
I get an Error
The process cannot access the file because it is being used by another process.
I have removed the Readonly in the Folder that it supposed to write to and gave everyone permission , but still the error persist.
