Use Process Monitor To Determine Which DLL Is Causing A BadImageFormatException?
Mar 8, 2011
I have a large web application, which is supposed to run in a 64 bit process. However, when I set "Enable 32-bit Applications" to False on my App Pool, I get the following error trying to run the app in IE:
is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
The application name at he beginning of the error message is missing, i.e. I have not lost it during copy and paste.
I have been advised to use Process Monitor to determine which application/DLL load is actually causing the error, but I have no idea where to start with this.
EDIT: I have tried filtering Process Monitor on only w3wp.exe and only file system and process events, but simply attempting a navigate to the root URL yields 34,012 events.

I have a producer-consumer scenario in ASP.NET. I designed a Producer class, a Consumer class and a class for holding the shared objects and responsible for communication between Producer and Consumer, lets call it Mediator. Because I fork the execution path at start-up (in parent object) and one thread would call Producer.Start() and another thread calls Consumer.Start(), I need to pass a reference of Mediator to both Producer and Consumer (via Constructor). Mediator is a smart class which will optimize many things like length of it's inner queue but for now consider it as a circular blocking queue. Producer would enqueues new objects to Mediator until the queue gets full and then Producer would block. Consumer dequeues objects from Mediator until there's nothing in the queue. For signaling between threads, I implemented two methods in Mediator class: Wait() and Pulse(). The code is something like this:
Class Mediator
{
private object _locker = new object();[code]....
Inside Mediator I use this.Pulse() every time something is Enqueued or Dequeued so waiting threads would be signaled and continue their work.But I encounter deadlocks and because I have never used this kind of design for signaling threads, I'm not sure if something is wrong with the design or I'm doing something wrong elsewhere ?

In my ASP.Net page, I allow users to download files from the server. If the file is of even a moderate size (does it with a 40 meg file, for example), when downloading, it fails with the error message:
"Insufficient system resources exist to complete the requested service".
I've checked out the server, and it's quiet (CPU, RAM, Hard Drive, Task Manager Processes, etc all very low in their numbers).
I've run the code from several client machines and I'm getting this error message no matter where I run it from.

We 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.

I've had this project running for a couple of months using a couple of company-specific DLL's. I just downloaded and updated to the newest version and I am now receiving this error. I don't believe it is specific to the DLLs themselves, more something in my project not expecting new versions. The stack trace isn't very helpful.

I've been working on a project that's been a rather seat-of-the-pants experience. We have MOSS 2007 and Silverlight 3 installed. We're trying to make use of some new 3rd party software, Visual Fusion([URL] While working through the tutorial I ran into a bit of an issue. All I really have to go on is the guidance package and sample stuff they provided so it's still a little fuzzy. Basically when I debug the project in Visual Studio 2008, instead of loading the default.aspx page, I get this on my browser instead:

I have a small app that is used to register users to the system. I am interested in having a log that will tell me, who - userid that logs in, what they do, how long. meaning, the rows they look at or update. I suppose to make a small table for this logging. lets assume a small table with only 2 columns, timestamp and the userid. It would be good to get some kind of ip address for identity.
the other parts will begood to know and interesting to learn how to code but less critical.
the signon.aspx you can see here. Is this where to 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'm using SqlDependency to control my cache. I want to use it to monitor several tables (around 10). There should be one SqlDependency per watched table.
Should I create for each of them code like that:
public void CreateDependency_Table()
{
if (connectionStringSettings != null) [code]....
or can I reuse something between them? Like connection?Is this the preferred way of setting multiple notifications?

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'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?

Can I objectively determine if my production ASP.NET web application is resetting its application pool? It could be for whatever reason (for example, an error occurred or memory topped off). I don't have direct access to my production servers, so when I want something on the server, I have ask specifically for it like PerfMon counters to run. It is a running IIS 6.0. I understand that I could use PerfMon to catch ASP.NET Application Restarts. If I was not monitoring that PerfMon, is there anything that can tell me the application restarted sometime in the past?

I need to monitor my application from incoming http post and get requestf originating from outside and sometimes inside the machine.
Is this possible?
Been using fiddler but this only does outgoing not incoming (from outside the machine) or have I configured it incorrectly?
This is for my web app that is meant to be receiving a POST from an external server.

I have built a web page that does a complex processing, and I realized recently that I need to convert it to a windows service running at the background and keeping the web page for monitoring and initiating the service.
The service will process some files, and provides information messages to the user.
I'm not sure how to implement the link between the windows service and the web site, but i was trying to avoid using MSMQ to connect both application together.

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?

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();
