hello, I was wondering if u can hook into a specific process memory and not the hole memory itself, I'm working on visual studios, and I'm trying to make a console app where you can hook a process by saying a console line, kind of like a command

What I have tried:

like if u imported kernal32.dll to the console app and then u write process memory by saying Select (Process)

Console.Write("selectProcessname")
{
}

Firstly you need to get the name right: kernel32.dll. Secondly, you can only write into process memory that belongs to you, not space owned by other processes.

OH, i though using kernal32.dll was supposed to go into the process or at least writing process, with writeprocessmemory, sorry if I mis corrected that, but can u atleast show me how to hook into process?

Whether you can or can not, "hook" by itself is pretty vague and useless. e.g. "keyboard hook" provides some clarity.

First, stop saying "hook into a process" as it is meaningless in the context you're using it.

What you are looking at is OpenProcess[^], which will give a processHandle you're going to use with ReadProcessMemory[^]

what if i wanted to find process by window then cant find window else openproccess and readprocessmemory.

That depends on how you are identifying the window.

Google for "C# Get process by window". There's a bunch of different ways to do this.
