System - Process Can't Access File
Aug 20, 2010
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:
protected void btnSave_Click(object sender, EventArgs e)
{
string serverpath = Server.MapPath("\proactivcust.ini");
string mappath = "";
string qbpath = "";
string archpath = "";
string workpath = "";
try
{
System.IO.StreamReader file = new System.IO.StreamReader(serverpath);
[Code.....]

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'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();
}}

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 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 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);

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 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);

What is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.
Approaches I can think of (and their disadvantages):
1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?
2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.
3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.

I have an ASP.NET page that I need to have access the local file system. It's an intranet. I need to download a zip file and an executable to a temp location and then run the executable.
Then afterwards, I need to delete the contents via an ASP.NET page.
Is there any way to access the local file system? Generally, I would think this would cause a security concern, but I've seen posts about Silverlight being able to access it.

I have been given a task of reproducing the issue/testing the unauthorized access to file system through request.param and query string.
For instance i have something like this. request.querystring("blah");
How could somebody pass "../../../b1/b2" in the query string and access file system.
This may be related to cross site scripting.

When I run System.Diagnostics.Process.Start from my console application it works but the same code when I run from my web service hosted in IIS doesn't work.
Is it some thing to do with ASP.Net privileges?? if yes how can I configure it from my C# code.

I need to use [System.Diagnostics.Process ] class in my web project to execute a *.exe file. I can also use the [CreateNoWindow ] property to make it invisible while it does it job behind the scenes. However, webhosting companies do not allow .exe files to be executed on the web. I read some where that if I place the same code (which invokes the .exe file) in a separate class library project and use the respective [dll] in my web application, it will work.

I am in the process of creating an audit trail system. Simple enough. Certain fields require audit trail. What is the best design concept to allow this to work in multiple applications without having to change much? I would of course leave it to the admin of the site to add what fields should be audited, but the logic is the problem. Would implementing the interface IComparable be a place to start? My initial thinking is to compare 2 arrays against eachother and do an insert of what fields are in question. Array1 are the fields in the form, array2 are the fields from the sql table that require auditing.

I can not run System.Diagnostics.Process.Start(@"wmplayer.exe") in code behind under IIS, - nothing happens, though I can do it successfully using Visual Studio ASP.NET Development server. I read topic http://support.microsoft.com/kb/555134 and made as recommended: 1) Made ASP.NET worker process run in SYSTEM account 2) Enabled IIS Admin Service to interact with desktop and rebooted serivce. - wmplayer.exe does not start, even its process does not start. I tried start notepad.exe and it partly works - process starts, I see only window frame, but not menu and can not interact with it. The other thing I tried is to put it under out-of-process (IIS virtual folder properties) and gave the process administrative rights (changed identity in Component Services): no result.

I have code that runs under IIS6 & ASP.Net 2.0, that won't run under IIS7.5 on Windows Server 2008 R2. I am assuming I have a configuration problem - but I don't know. On a Windows Sever 2008 R2 system: From inside IIS (v7.5), an ASP.NET process will not connect to port 21 (ftp) on the ICS (using System.Net.Sockets.Socket), it fails, logging an error that it cannot connect to the system at nnn.nnn.nnn.nnn. But, from a command prompt on the same server though, I am able to connect via ftp to the system at nnn.nnn.nnn.nnn. I am using the DefaultAppPool.
Here's a code snippet:
[Code]....
And the connect throws an exception - unable to connect I'm firing up wireshark soon and I'll see what if anything is getting across the wire? particularly if you think it's administrative in nature, cause that's a real weak point for me.
