Hello, Do you know a guide on how to make a memory scanner in C++?
For help thanks.

this topic has been asked quite a few times on this forum, a quick use of the search functions gave me these results:

Thanks!
But I can't build this. Can you make for me full complite simple memory scanner? ;> Please....

I making a bad... simple... memory scanner but most important thing is to make it work. I intend to use WirteProcessMemory and ReadProcessMemory.
But what to do as ReadProcessMemory find me some addresses where I store them? And then the second scan compared with that any number of Address? Please help...

Btw the first two snippets are mine and I would advise against using them. I wrote them when I was first starting out in C. A better way would be to have a model that deals purely with data and then update that only. Then you would have a view which is bound to the model. In this case the model should have no concept of the view though.

Mostly I mean here is that the value entered in the console memory scanner 10 then looks for me to address the value of 10 and then do another scan but now entering the value 15 then searches me this one adress and change its value to, for example, the 100.

What do you use a memory scanner to look for all the addresses with a value of 10?
And where to store all those addresses?
And how to make a second scan of the negative bad addresses?

I'll talk this through to you theoretically then you can think how to implement it in code. Memory is byte addressable so if you decide to search on unaligned addresses you will basically want to iterate through every readable address. You need to use some method of finding out what ranges of addresses are readable. Once you have this list, check each address in that range for your value, let's say 10. You now have a list of first scan addresses. For the next scan, you simply need to iterate through this list and check which of the addresses now point to the value 15. You can store the addresses however you like - in memory, on disk, etc.

You have a long way to go before even attempting something like this. Learning about arrays might be a good start. Although you should actually learn the basics of the language itself first.
