 |
|
Hi,
First Question:
I want to read a word, wich is saved on an address in Unicode.
I've found the address easy with Cheatengine, but:
If I use "readprocessmemory" in c++, I'll get only a "4bytes" Search.
(In unicode, 4byte --> 2signs)
So I get only the 2first letters.
How can I get all letters? (5 in total btw)
second Question:
When I read the first 2letters with readprocessmemory, I'll get a number ofc.
How to translate thise number into letters?
(I'll get 6357107 , wich means "sa" (I know it, becouse I knew those letters, befor I knew this number)
But for example, what does 7667827 mean?

| Code: |
char buffer[5] = "";
ReadProcessMemory(hProcess, 0xDEADBEEF /*replace with real address*/, &buffer, 10, NULL);

ty, but this doesnt work very well.(atleast in my case or I'm doing something wrong)
I get the first letter (s) saved in buffer, but only this one.
After I close my program, following error pops up:
| Code: | | Run-Time Check Failure #2 - Stack around the variable "buffer" was corrupted |
my part of code:
| Code: | char buffer[5] = "";
ReadProcessMemory (hopen,(VOID *)0x209E65C, &buffer, 10, NULL);
std::cout<<buffer<<std::endl;

Because you're trying to stuff 10 bytes into a 5 byte array..
| Code: |
char buffer[5] = "";
ReadProcessMemory( hopen, ( void * )0x209E65C, &buffer, sizeof( buffer ), NULL );
std::cout << buffer << std::endl;

y, right jackyyll, also just saw that.
Anyway, the error doesnt pop up anymore, but it still saves only the first letter.

If the address is stored as Unicode, then shouldn't it be..?
| Code: |
wchar buffer[5] = L"";
//...

And according to the OP, two bytes is a character in Unicode (true/false?). Which is why I happened to read 10 bytes (5 characters, 5*2=10).

A unicode character is two bytes. 5 Unicode Character * 2 bytes each = 10 bytes so you need char buffer[10], or just wchar buffer[5].

Sorry, I never used wchar before.
What do I need to include to use this?
( <wchar.h> ?, but then it still doesnt work:
error C2065: 'wchar': nichtdeklarierter Bezeichner)
if I use wchar_t , it shows the "number" , instead of letters.
But I think U're right, if I uncheck "unicode" in cheatengine, it also shows only the first letter.

he could just use a multi-byte character set instead of unicode.

Yeah, a Unicode character is 2 bytes, but you were just reading regular characters, which are only one byte.

char is Ansi/Multibyte, not Unicode.

try
char * Buffer;
ReadProcessMemory( hopen, ( LPVOID * ) ( DWORD ) 0x209E65C, &Buffer, sizeof( Buffer ), NULL );
std::cout << buffer << std::endl;
