Hide in Task Manager.

astrovirgin

Hi Everyone, I have created an windows application in c#.net. Now what I want is that when I run the application, it should not be visible in Task Manager. Please help. Thanks in advance.

Why would you want to do that? The user should always retain control of their PC.

Hi astrovirgin, I would say that this is not possible. Your application will run as a process on your system, so you will see the process in the task manager. By the way, you are not developing some evil software, are you??? Regards Sebastian

It's not a bug, it's a feature! Me in Softwareland.

Its not possible. Any application running will show as a process in task manager. And I agree with Simon, the user should always be in control of his/her pc. Would you not want to be able to kill something when it lets your pc freak out..?

Can't be done.

If it is just removing from the application tab of task manager then set ShowInTasbar property to false for the application.(Yes it removes the application from both task bar and task manager). If you wish to hide the process as well, then I think you should look into the NtQuerySystemInformation Function. MSDN will surely help you find something useful. Just make sure you handle your code very carefully.

No it won't. There are plenty applications that can be seen in the Task Manager that have no visibility in the Taskbar.

I just tried it and it worked for me(just from the application tab not from the processes). I am not sure about the cases where it wont work. Probably in ones where "Minimize to tray" feature is provided. :~

What valid reason could you have for wanting to do this? The whole point of showing things in the Task manager, is to provide information about the process and give the user the chance to kill the application if it starts to run away. The only applications I know of that try to hide their presence are generally malicious.

That is easy, just replace taskmgr.exe by something you develop yourself. :)

And then get hired by Microsoft. Head up one of the OS development teams. It shouldn't take too long.

No thanks. I would consider rewriting Task Manager if I really felt a need, which I don't, but it has to end there. X|

That is first thing that comes to mind when someone asks this type of question. What is it they are developing that they want to hide so bad? :suss:

There isn't any valid reason for it. As mentioned in the other post by others, the user must be able to control their PC and be able to kill processes when they have to.

That is the impression I get.

creating trojans there :-D well when you load task bar all current processes will appear/show, what trojans creators usually do is to name the process with a not suspicious, inocuo or commom name, you know? :-D But try to find a way to trigger the turn off of your trojan when the user hits the taskbar! after trigger the turn on when the taskbar closes. bad luck to you, darkvader :doh:

For a C# (or .NET) application, this is not easy at all. The main issue is that the .NET framework did not provide the necessary API to acomplish this task, so you have to reside on Win32 API, or, even on kernel API.

Just saw ur question... Actually this is VERY possible. I made a code that hides the process from process tab. When u look at running process number, it stays the same, but the exe process isnt on list anymore. Quite hard to do, but possible :)
