Where is app pool located in visual studio? - c#

I'm having trouble finding the app pool, I need to set my app pool to allow my crystal report to run properly. On my computer where I develop the application, it works properly but when I try to run the program on another computer it won't run, I've read similar articles about it here, but I can't finish the last part, where #Matt Palmerlee said that I need to set the application pool for it to work properly.

You are not using IIS server because your project looks like for local machine only.
The location of app pool is in IIS server looks like the answer above which is you don't need it i guess.
If your project did not run from other PC:
Install the version of crystal report like the version of your development side.
Use 32-bit crystal report run time.
Hope it helps

You may need to carry out a bit more troubleshooting, but if you need to configure the application pool, here's how to get there:
Open IIS (Internet information services) normally by clicking the start button and typing IIS
Application pools are the second node. Find the pool your application is using and change the properties.

Is it possible to run selenium as a windows service using C#? [duplicate]

So that we may perform front-to-back web UI testing, we are using Selenium and ChromeDriver to automate page loads/interaction as part of our testing pack.
This is behaving as expected during developer testing (on a developer's local machine), but we are struggling to perform these checks as part of our continuous integration build.
Our server plant is *NIX based, and all of our CI infrastructure runs on these machines. So that we may test Chrome under Windows (our delivery mechanism), we have configured a Selenium Grid. When the CI tests run, they access the grid, in order to locate a Windows node to run the tests on.
We have had a Windows desktop provisioned solely for the purpose of running these tests. This contains our standard enterprise build of Windows 7. This machine will be periodically rebooted in-line with the IT department's update policy.
In an effort to ensure the Selenium server is always running, we have added the Selenium Server (running in "node" mode) as a Windows service. The selenium Server is configured to start-up ChromeDriver to invoke the simulated user-interaction.
However, when running the tests from CI they fail due to timeout. Our working theory is, the system user that is running the service cannot create interactive windows. A web search has raised reference to the "Session 0" problem, but with little to no constructive advice on how to move forward.
Starting the Selenium Server process manually from an interactive session is not a viable solution, as this is leading to brittle tests - which are failing due to an infrastructure problem, rather than a genuine test regression.
How can we have an instance of Selenium Server started via a Windows Service whenever the system reboots, that is capable of launching Chrome instances?
It could be easily done with NSSM.
Installation of services looks like these:
nssm install seleniumhub java -jar C:\selenium\selenium-server-standalone-2.45.0.jar -role hub -hubConfig C:\selenium\hub.json
nssm install seleniumnode java -jar C:\selenium\selenium-server-standalone-2.45.0.jar -role node -nodeConfig C:\selenium\node.json
It provides easily way to remove service if needed:
nssm remove seleniumnode confirm
Add destination to nssm to your PATH variable and run from console as admin
UPDATE April 2021
NSSM is not supported for more than 3 years. So please consider other options like winsw or any other. WinSW does the same job as NSSM and allows to keep run configuration in xml.
You cannot run Selenium Grid as a windows service ever since Windows Vista. Microsoft calls it "Session 0 Isolation". You could do it in Windows 2000 or XP but since the time that Vista came out, Microsoft no longer will let Grid interact with the desktop (or any other UI programs for that matter). Regardless of the fact that you still see that "interact with desktop" checkbox, it is a red herring. So, you MUST run Selenium Grid in the foreground on that server in order for it to get access to the session. If it is running Windows Server, you could in theory have multiple sessions and leave Grid running in the foreground on one of the non-zero user sessions.
Right now you can't help it - it used to work fine in session 0 but for the past few days after chrome update only works for interactive sessions.

https://code.google.com/p/chromium/issues/detail?id=422218
My preferred solution to this problem (and my default choice for running Selenium Grid as a service) is to use a simple tool called AlwaysUp. It has a free 30 day trial to try it out.
What to do:
Download AlwaysUp
Configure AlwaysUp to start the Selenium Grid node on startup
Configure AlwaysUp to run the Selenium node as a specific user (not the default System user)
This way the the node will run as a service, survive machine restarts and work with the latest version Chrome.
If the user account you use to login to the machine is different from the user account you specify to run the node as a service then you will not see the browsers pop up on the desktop as they are running in a different user session. The end result is that it is almost identical to running as a normal service but gets round the Session 0 issue.
Yeah, you should use NSSM. Important is, that you add your windows account in the "Log on" tab, or any other valid account. If you run your node with the "Local System account" option, you will get the session 0 problem. With a normal user session, the nodes run smoothly invisible in the background :)
we don't use selenium GRID, we were disappointed with its stability. We use a "Jenkins Grid", that is jenkins slaves nodes on various servers.
The slaves are services with the interact with desktop flag. They run as services with NSSM, and the SERVICE_INTERACTIVE_PROCESS flag. Making sure that NoInteractiveProcess is set to 1 (cf https://learn.microsoft.com/en-us/windows/desktop/services/interactive-services).
We don't have the fancy features of the grid (that is balancing according the browser types slots). Instead, we have Jenkins balancing the test jobs using a slave node or another.
Initially we did not use the interact with desktop flag, having browsers to run without "real" display, but the behavior was not very stable (especially with resize commands).
Hope this helps.
As I explained on this thread, I found that using a small paid tool FireDaemon Pro saved me a lot of time from trying to configure NSSM and other free tools.
It works well in the background, and restarts Selenium along with the server, which was my main requirement for running Selenium Standalone Server as a Windows Service.
This free tool would probably do it:
http://yajsw.sourceforge.net/
For that to work, you need a wrapper.conf file and a script to run the YAJSW wrapper. I takes time to read the documentation, but it is a free solution.
I wrote an example shared here, that installs JBoss7 as a Windows service.
Of course, you can simplify my example by a lot.

Printing from a console that is started by a Windows Service [duplicate]

I'm building an ASP.NET application that requires printing using PrintDocument method:
PrintDocument.Print()
Printing works properly in development env with IIS express. when publishing it to an intranet IIS server, printing fails, which I think is caused by permission issue for aspnet working process.
I tried to do the following with no success:
I created an application pool in integrated pipeline mode for an admin local user with load user profile option set to true
I moved the application to the new created application pool
I added <identity impersonate="true" username="username" password="*****"/> in web.config file
An error appeared stating that: An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode so I added <validation validateIntegratedModeConfiguration="false"/> to <system.webServer> section.
Any help please?
I think you might be misunderstanding some fundamental concepts here. When you use PrintDocument.Print() you are printing on the server. When you deploy your application in IIS this printing will happen on the server computer that is hosting your application. The reason why you thought your code was working in IIS Express is because you were hosting your application on the same computer as the client browser that was testing it. Also you were running your application under your account which had a printer configured.
You cannot print directly to the client computer from a web application. That would be a big security issue. The best you could do is provide some HTML document using a print media CSS type. Then if the user decides, he might print it in his browser.
If on the other hand you want to print on some printer that is attached to your web server, you will need to configure the Application Pool in IIS to run under an identity that has a printer configured in its profile.
Hopefully I am understanding your question correctly, but I just had some confusion myself with this. Our setup at my work is Windows Server 2008 R2 with IIS 7.
We have a print server as well installed on the same box (not sure if it matters as this is not my area of expert).
Basically, viewing the installed printers using, PrinterSettings.InstalledPrinters I was able to see all the printer names installed on the server.
I attach a debugger to the application process to debug and I can just use the debugger to see this, otherwise you will have to run a loop to print through these. If you run this locally, you will see only the printers installed on your machine. If they are network printers, then the full path will be shown. So determine the path/name the server will recognize the printer as and then set that to the printer name explicitly using the,
PrinterSettings.PrinterName property of the PrintDocument class. This worked for me. Also, my application pool identity is set to NetworkService.
I think the original poster has gotten a lot of flack for their question. If you want to generate .PDFs using GhostScript, for example, you install a printer driver and create a printer for it. You can suppress the Saveas() dialog in many languages by providing one ahead of time. This was feasible in earlier versions of IIS (that may have been less secure), but is harder to do in IIS 8.
I think this issue is caused by IIS inhibiting access to the local printer queue. This is either caused by not being in the NT AUTHORITY\INTERACTIVE group at runtime, or because IIS will put the user, (whomever is running the app pool) in two groups: IIS APPPOOL\, and BUILTIN\IIS_IUSRS.
You can validate all this by looking at the thread permissions using a tool like Sys Internal's Process Explorer.
I have faced same issue and I found the following solution and it worked for me.
1 - Go to printer and setting of system
2 - Select Printer
3 - Go to Printer Properties
4 - Security
5 - Click on Add "IIS AppPool\DefaultAppPool" as object name and click on check name (Default Pool will be your Pool Name)
6 - Give permission Manage This Printer and Manage Document permission.
7 - Restart IIS

ASP.net: Could not use <database file>; file already in use

I have an ASP.net web application (C#) hosted by IIS on my server that connects with an Access database. It's important that I can have the database open in Access and still use the website at the same time.
I get the "Could not use file; file already in use" error whenever I try this. I've done a ton of research on this topic but nothing really seems to work.
I have modify permissions added for IUSR, NETWORK SERVICE and IIS_IUSRS for the folder containing the database. None of this seems to work.
Oddly enough, I tried hosting the website from my local machine and the solution above solved the issue, but it does not work when hosting the website from my server.
My website also chokes up when trying to do an INSERT statement even when the database is closed. I get the error "operation must use an updateable query"
Any thoughts? Thanks.
In regards to:
but it does not work when hosting the website from my server
I am not sure about the rest of your configuration, but this may shed some light onto why you are getting different behaviors on different systems:
You should enable the same permissions (for the Database folder) for the Identity under which the Application Pool you have configured for your Application in IIS.
Open your Server's IIS Management Console
See what the Application Pool is for your App
right click on the Application node:
'manage Application' >> 'Advanced Settings' >> Application Pool
Open Application Pools View: Find the App Pool
right Click the App Pool >> Advanced Settings
Look for the Identity value
That is the Identity you should replicate the permissions for as you did on your local machine's folders
P.S.: It is usually recommended that you configure/create a dedicated App pool for each of your applications.
Hope this helps resolve your issue.

Auto restart IIS Website from console application

We have an ASP.Net application used by many customers installed on their own servers. Because it is installed on their end with each having different databases and URL bindings etc I created a console application a while ago that gets a zip file and extracts it to c:\inetpub location to append the latest application changes. This console app is added to scheduled tasks to create an automated update.
Obviously when anyone accesses the site for the first time after it does this they have to wait a little longer whilst the site rebuilds. I changed the console application to include a Process.Start(urlofapp) so that it should hopefully do this as part of the update so the next morning that first user doesn't have to wait for the rebuild.
I have tested it ok running myself but not yet released as my concern is that this url process is kept open. Can anyone enlighten me as to whether this would be the case as I don't want this to happen or can give me any ideas as to how to rebuild the site manually as part of the console app.
IIS has had an auto-start apps feature for quite some time. You just have to enable it. You can find more info from the Gu, and the IIS site.
Safer instead to use a start page which loads everything on the server in the background. If you do this logic in an async method which in turn is called from an MVC controller for example then this can potentially run whilst the main page has finished. Alternatively use a threaded Task and show a start page that is only returned whilst setup is taking place.

Remote desktop idle time

We have an application that requires to be continously run but it can't run as a service so we run it in Windows 2003 console session. After migration to Windows 2008 and with the session 0 isolation, the GPO causes the session to teminate after the session is idle for 30 minutes.
I wrote a little C# application to simulate key press using sendkeys.send and sendwait but the remote desktop session still gets connected. Any source code or idea to keep the session permentantly active other than changing the GPO as this isn't possible for the time being?
I think there are prob two options you could look at for obtaining the desired effect.
1) SrvAny.exe - this is a tool provided by Microsoft, that will take any exe and run it from the services control panel. While there is no version that officially supports server 2008, the version that works on server 2003 works just fine. I've used it to run dropbox has a service in the past.
Here is a tutorial that does something similar with dropbox Dropbox as a service on server 2008
2) Write a stub application that will run as a service and do nothing more than launch the exe from the vendor.
I realize this is not what you asked persay, but it would give you the desired effect.
