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?
View 10 RepliesI'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?
My 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
{ lognewuser();
}}

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 an asp.net website and I allready did .Dispose() here is my code below;

MediaTypeNames.Application.Octet);

}
newMail.BodyEncoding = System.Text.Encoding.UTF8;
newMail.IsBodyHtml = true;
SmtpClient client = new SmtpClient("192.168.2.205");
client.Credentials = CredentialCache.DefaultNetworkCredentials;
client.Send(newMail);
newMail.Attachments.Dispose();
newMail.Dispose();
DeleteAttachment(MailAttachment);

But i' m getting the same error, it' s running fine in my localhost but in server i' m getting this error. How can i fix it?
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.
System.IO.FileInfo FileInfo1 = new System.IO.FileInfo(filename1);
FileInfo1.CopyTo(strDestPath,true);
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.
I am trying to download a file from the server but i am getting this error:
The process cannot access xxxx the file because it is being used by another process
This is my CODE:
string fileName="DownLoadFiles";
string filePath = hid_filepath.Value;

System.Net.WebClient wc = new System.Net.WebClient();
wc.DownloadFile(new Uri(fileName, filePath);
Foe ur Information:the file is not opened or not used.
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'm trying to write a text file form my web page, But every time I'm having this error System.IO.IOException: The process cannot access the file '.txt' because it is being used by another process. This is mode code for write file.
Code:

{
string serverpath = Server.MapPath("\proactivcust.ini");
string mappath = "";
string qbpath = "";
string archpath = "";
string workpath = "";
try
{
System.IO.StreamReader file = new System.IO.StreamReader(serverpath);

I simply want to create one file and then delete it, means I want to access one file subsequently. I am getting the very familiar error as shown in title. (Process can't access the file,) I have tried using file stream and all other stuff that I found from Googling but no success so far. Does any body have small and neat solution? in short, I would like to run the following statements without any error.File.Create("C:\hsp1.txt");
File.Open("C:\hsp1.txt", FileMode.Open, FileAccess.Read, FileShare.None);
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
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?

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.
I am trying to use the unmanaged ImageMagick library in my ASP.NET application from the command line using System.Diagnostics.Process. Basically, users will upload an .eps file to the site, and then I will run the command line command to convert it into .jpg. This is the code I'm using to try and run the command:
Dim proc As New System.Diagnostics.Process
proc.StartInfo.RedirectStandardOutput = True
proc.StartInfo.RedirectStandardError = True
proc.StartInfo.FileName = "C:Program Files (x86)ImageMagick-6.6.1-Q16convert.exe"
proc.StartInfo.UseShellExecute = False
proc.StartInfo.Arguments = String.Format("{0} {1}", Server.MapPath("~/logo/test.eps"), _
Server.MapPath("~/certificates/temp/test-1234.jpg"))
proc.StartInfo.CreateNoWindow = True
proc.Start()
I am able to run this code just fine on our development Win 2k3 server, but not on our production Win 2k3 Server. I get the error "System.ComponentModel.Win32Exception: Access is denied". The main between the two servers is that the production is 64-bit and runs Plesk to manage multiple domains. I've tried adding rights asp.net user to the ImageMagick directory. The PS Admin says that in the case of Plesk, it's the same account that I use to access the site in VS using FPE. Does anyone know what I might do in order to allow this process to run on my production server?

I have a project with C# ASP.Net. I should create a web site which has categories.There will be a button and textbox and when I click this button there will be created a new web page and button and what I wrote text box it will be new button's text. At the same time, this created button's text will saved at SQL Server.I tried a create new button on page load but when I execute the project the button was created but I want to create with another button.These are for buttons; and these are for a new web page;(but there is an error -->Sayac.txt is already using)
sayac =int.Parse(rdr.ReadLine())+1;
File.Copy(MapPath("_template.aspx"), MapPath("WebForm" + sayac + ".aspx"));

I'm developing and maintaining an ASP.NET web site.
The site is hosted at the 3rd party company running IIS6.
Recently the hosting service provider has setup an additional IIS server and moved part of the applications to this new server. This moment, my application is installed on both old and new servers.
Although the hosting provider claims that IIS configuration on the both servers is absolutely equal, I get the following exception on the new server, while on the old one everything works like a charm.
[Code]....

System.Web.UI.Control.LoadRecursive() +50
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627
According to the service provider in both cases my application runs under Network Service user account.
An additional observation: retrieving the "System.Environment.UserName"
shows "Network Service" on the old server and "IUSR_XXX" on the new one.
I loose my head trying to understand what is different and what I need in order to make the things working.
