A very easy byte-pattern search implementation using modern c++ & automatic mask creation.
When you write a program, the program is firstly ran through another program called a compiler. compiler turns text-based program into an executable, which can be ran by the OS. This is executable is nothing else then just sequence of bytecodes.
If a module is loaded into process memory, that module is also a sequece of bytecodes. Knowing this fact, you can search for a specific sequence of bytecodes inside that module to locate a specific address.
This method works everytime, unless there are some changes made to the specific module area we're searching in.
The class uses automatic string length deduction using templates. Having a power of pattern length knowledge is good, because we can utilize it for automatic creation of mask, which is necessary for the search process.
The main.cpp file demonstrates the bacic usage of the byte pattern scan. It searches for the MessageBoxA function located inside user32.dll module.
