Detecting instances of Internet Explorer for all users logged in
-
Hi, i have a windows service which is executing EnumWindowCallBack as shown in the following link Capturing the Running IE Instances in C#[^] The service is running as LocalSystem account and is interacting with Desktop. The service is writing all URLS opened by me in a text file. It is working fine for me BUT when i switch as a different XP user, and open any IE window, The service can not detect this new IE window. My aim is to get running instances of IE for all users logged in. Can some one help. I can send the code if any body is willing to help me. Please help me :confused:

My guest, your program or the service the program depend upon is running inactive or a mode that is blocked by windows log in user security service. You could try if the program will work on both administrative users. ;)

Are you sure that the service is running when you log in as another user? If the service is running under the LocalSystem account it does not make sense that it would only work for your user account.
Hi Scott Yes when i switch as another user (xp limited user), the service is still running. I cannot stop it ie. Access is denied. But when i open an internet explorer window, my service can not detect it and the log is still showing the same number of windows as opened by the admin user. I want this service to detect all windows for all users. Thanks

Hi SirDre If i make everyone an admin user, then they can kill my process, which i dont want. Actually this is a parental control system. Only the parents should be able to stop the service not the children. Thanks.

Only one user can be logged in at a time, so the service can only work for the currently logged on user. Maybe you have to reset something when a user logon event is detected.

OK, what are you trying to control with this? Are you trying to prevent IE from running? Log all the URL's that are in each IE window? What? From what I'm assuming you're doing so far, you're going about it the wrong way. But, I'll leave confirming that up to you before I way anything.

But no longer in 2009...Hello Dave.. Basically parental control system is a service (PCS.exe) which will run under LocalSystem account and interacting with desktop. When other users (children) log in to the computer as limited users, PCS will do the following jobs: 1. Key logging -- already implemented 2. Screenshots logging -- 3. Restrict some applications -- for example sol.exe or calc.exe. My Service read these program names from xml file and will kill the process if found open. System.Diagnostic.Process works very well here. 4. Restrict websites -- This is giving me hard time. Basically my service can find internet explorer windows and URLS being visited very well in current user session. But when i switch the user, the service cannot see any explorer window. PROBLEM: The main problem right now is. If PCS.exe is running under local system account, if i want to kill a process for user A, it says Access Denied. If i run PCS.exe under user account A, it cannot interact with desktop. How can i make it able to kill a process for not only current user but also for any other user who is logged in. I hope i have explained what i am doing or wish to do.

That's because this better handled by a proxy or firewall. You don't need to delve into every single users session to find every IE browser window. Besides, youre technique will only work with IE. It will not work with any other browser.

Better handled by Group Policy.

Useless. You can take snapshots all day long and still miss what you need to see.
