How can i read a string from memory?

Question

I'm working on a c++ windows application project. A portion of this project requires me to read the value of a memory address used in a separate process and use this value as a "trigger" within a function. I know the value is a string, and constantly changes, but i have no idea how to read or use it. Any ideas? Any help would be wonderful.

Are you allowed to use standard IPC? If not, you're going to run into issues. Processes are not supposed to share memory space like that. In fact, if you compile with standard settings and try to read outside your application's memory space, you'll get a fatal seg-fault.

What you're going to want to do is essentially design a very rudimentary debugger, which is no small task. I would recommend starting by looking at existing debugger source code (eg, x64dbg, or cheat engine: https://github.com/cheat-engine/cheat-engine ).

What is the purpose of this project?
