Hide or make my peocess invisible in task manager?

[sbscb]

I want to make my program invisible in the task manager while it runs some background functions to later be returned to the visible state in the task manager, since I don't want the user to kill the process while it is still working. I know there is a project already on here somewhere which runs in the system tray and lists all processes and has a button that can make a process invisible to the task manager but I don't remember the link to it on this site.

Imposible to hide process. You can hide window, But not process.

If someone kills your process, they are on their own. And no, you can't hide it.

I'm 100% sure it can be done because I have done it before in C# but don't have the full code but it has something to do with using APIs and sending a message to the process ID which causes it to be hidden in the task manager, here is the c++ project: Driver to Hide Processes and Files[^]

OK, you can hook the process that enumerates processes ? Interesting...

You can do that I believe but the last time I simply used SendMessage to the process with a special code and it made it invisible. I know the code was published somewhere but I still can't find it.

Good luck with that. There is no legitimate reason to do that.

I can't find it in C#, but you might be able to port this from VB... Good luck.

It can be done with App-Init DLL... Take a look at this: Easy way to set up global API hooks[^]
