That's a UTF-16 string, you need to use the wide version of the output function you are using, assuming you are using cout, what you are doing could be:

Code:

std::cout << string;

To show that string you have to do:

Code:

std::wcout << string;

In case that is not the solution, it could also be that you are reading with ReadProcessMemory the wrong amount of bytes, as size you cannot put things like "sizeof(wchar_t)", but the actual length of the string in bytes, which is "6 * sizeof ( wchar_t)" also counting the escape sequence '\ 0'.

(it would help in case you also post the code you wrote)

I already use . ReadProcessMemory function .
and i'm not strong enough in C++ language
So can you give me an example.
Thank you for helping me.

I used a 32-bit process as a target.

Code:

#include <iostream>
#include <Windows.h>

int main()
{
DWORD pid = 1337; // Pid stand for Process ID

HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, false, pid);

wchar_t wstring[256] = { 0 };
ReadProcessMemory(hProcess, (LPVOID)0x008D31C0, wstring, sizeof(wstring), NULL);

std::wcout << wstring << std::endl;

CloseHandle(hProcess);
getchar();
return 0;
}

And I am attaching the contents of the address 0x008D31C0 (the memory address on which the string is located).
