After upgrading an asp.net application to 2.0 from 1.1 I am receiving a large 100+MB .tmp file in C:Temp on the web server when the w3wp process serving that application crashes. If you open the file it looks like it is some sort of dump file. how to turn this off. I know what is crashing the application and process.
View 2 RepliesWe recently migrated our ASP.NET 2.0 application to ASP.NET 4.0. It is running on Windows 2003 with IIS 6.0. After migrating, we have found that the ASP.NET 4.0 worker process w3wp.exe crashes intermittently with an 'Access Denied' exception. The stack trace of the exception does not point to any code written in our application. We are clueless as to what could be causing this. The worker process crashes when it makes a remoting call over http.

Is it possible for an asp.net application to read a file which is used by another process?
View 9 RepliesI'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.
What is the difference between IIS Worker process, Application pool and application domain? Do we have more than one application domains in one application pool?Does one application domain means one virtual directory?
If we have 2 virtual directories pointing to same physical folder. Will they share the same memory or different when there instances are opened in the browser? Will they be in 2 different application domains?
I am trying to config my application to use out-of-process sessionState.

View 8 RepliesI converted a ASP.Net website to ASP.Net web app and changed the framework from 2.0 to 3.5
The web application works fine in Visual studio. However, If I compile the app in a dll, and try to reuse its middle layer in another web project, All the classes that have a static variable crash. Code like:
public static string myString = "Something";
However if I convert it to a property like this:
`public static string myString {get{return "Something";}}`
I have searched the vast information highway and found nothing but road blocks!I have created a simple web application that calls a COM object like we've all done before. Well this time, the COM interop don't want to work due to DCOM Identity CRISIS. The only way I can get it to work is to physically log in to the web server and thenrun my web application.
View 1 RepliesSo, I have a webForm that has an ImageButton. This ImageButton has to open a file (said file is uploaded by the user in another web form. The file is saved to \serverNamefiles; it can be a doc file, pdf file, excel file).
So this ImageButton should open said file as you normally would. It works on debug, however when I publish my site, and run it from my localhost, it doesn't open the file. When I click the ImageButton it just does the postback and nothing happens.
The code for the ImageButton is just:
Process.Start(fileName);
fileName has the full path of the file I want to open, in this case it has: \serverNamefilesmyFile.pdf
I have a web site that has always run fine for years and years under 3.5. I converted it recently to run under 4.0, and it runs on Cassini fine. When I attempt to deploy the app to an IIS7 server that has 4.0 installed, all I get is "internal server error", and no error messages in the Event log, and nothing in the http logs.
I've double checked that the application pool I've deployed to is running 4.0.
It's an x64 web server and app (always has been while it was under 3.5.
I have a folder called GUI. Inside GUI thers another folder called PDF and inside this folder, there are some PDF files. This folder (GUI) is uploaded to the server too. Then I have a WebForm with some ImageButtons. When I click one of these ImageButtons, I want the file to open in a new tab. I tried with the following code:
[Code]....
As you can see, I build the path using the tooltips of the different ImageButtons. The ToolTip = File Name I want to open. When I try this in debug mode, it works. It opens the pdf file in a new tab. However when I publish my website and upload it to the server... it doesn't work... when I click an ImageButton I get the following exception: No application is associated with the specified file for this operation

I'm downloading a file from my intranet site and on Chrome, it works as expected. But when I try it on IE, it crashes.
ASP.NET Code:
<a href="../nbd.exe">TEST</a></h2>
Is there something I need to do just for IE?
Also, it works fine in Opera and Firefox. So just IE...
I am working on a web application project to be deployed on an intranet. I need to provide users with the ability to allocate documents to projects so that I can show them a page that lists the documents for a project. When they click on the document I need it to open in the application that created it. Generally, just Word and Excel documents.
So, I've done all the 'Add a Document' stuff and I have a Gridview on the screen that displays the document name (test.doc) and the path (C:UsersFredTest.doc).
I have tried passing the Document Name and Document Path to this function:
Code:
protected void ShowFile(string DocumentName, string DocumentPath)
{
Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AddHeader("content-disposition", "attachment;filename="" + DocumentName + """);
Response.TransmitFile(DocumentPath);
Response.End();
}
and, for example, for my Word document it opens - but not before a 'Do you want to Open or Save this file dialog is presented' (unwanted, but not the end of the world) but, when the file opens you can't save it. (Even on my development box).
Is there a simple way of simply opening an Office document from within a .net web application project that just actually opens the document - so it can be edited and saved etc.
Edit: When the word file opens - if I click to save it it shows this as the path to the file:
C:UsersFredAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE57T5D07IATest[4].doc
So, it's not opening the original file at all - it's creating a copy of it. I want users to simply be able to click on a file and open it. If I use 'C:UsersFredTest.doc' as a desktop shortcut - click on it and the file opens - the actual file - you can edit and save it. Why is it so hard to get a Word document to open from within a .net Web Application?
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 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?

below written question :
1.) What is the name of the OS process in which App Domain resides.
2.)if suppose There are Three Windows application hosted on a same envoirment and two instance is working for each application at a Time, means now total instance are six .what will happen among the below written cases :
a.) There will be six different app domain in a single OS process
b.) There will three app domain(one for each application) in a single OS process and some Parallel thread will be executed in each app domain for another instance.
c.) There will be Three OS process corresponding to each application.
3.) If eveything will remain same except there are three web application in place of windows in point 2, will there be any change in functioning.
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.
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);
