| Code: |
int addr;
ReadProcessMemory(CSettings::phandle, (LPCVOID*)(DWORD*)CSettings::base + 0x00FD1D9C, &addr, sizeof(addr), 0);
ReadProcessMemory(CSettings::phandle, (LPCVOID*)(DWORD*)addr + 0x60, &addr, sizeof(addr), 0);
ReadProcessMemory(CSettings::phandle, (LPCVOID*)(DWORD*)addr + 0xA4, &addr, sizeof(addr), 0);
byte* cname = new byte[24];
ReadProcessMemory(CSettings::phandle, (LPCVOID*)(DWORD*)addr, &cname, sizeof(cname), 0);
char* data;
hexArrayToStr(cname, sizeof(cname), &data);
cout << data;
delete cname;
delete data;

How about this?
I get no errors no nothing and instead of a string of 24bytes it prints an hex address.
When I enclose it in () like so, I get access violation at hexArrayToStr:
| Code: |
ReadProcessMemory(CSettings::phandle, (LPCVOID*)(DWORD*)(CSettings::base + 0x00FD1D9C), &addr, sizeof(addr), 0);
ReadProcessMemory(CSettings::phandle, (LPCVOID*)(DWORD*)(addr + 0x60), &addr, sizeof(addr), 0);
ReadProcessMemory(CSettings::phandle, (LPCVOID*)(DWORD*)(addr + 0xA4), &addr, sizeof(addr), 0);

Why is the third address thats printed not what it should be?
Is ReadProcessMemory shifting bytes or something?
| Code: |
int addr = 0;
ReadProcessMemory(CSettings::phandle, (void*)(CSettings::base + 0x00FD1D9C), &addr, sizeof(addr), 0);
printf("Addr : 0x%08X\n\n", addr);
ReadProcessMemory(CSettings::phandle, (void*)(addr + 0x60), &addr, sizeof(addr), 0);
printf("Addr : 0x%08X\n\n", addr);
ReadProcessMemory(CSettings::phandle, (void*)(addr + 0xA4), &addr, sizeof(addr), 0);
printf("Addr : 0x%08X\n\n", addr);
|
OUTPUT:
| Code: |
Addr : 0x100A81C0
Addr : 0x15427890
Addr : 0x00610053

0x15427890+0xa4=the address of the string
you don't need to read that as a pointer, but as a string
so instead of
| Code: |
ReadProcessMemory(CSettings::phandle, (LPCVOID*)(DWORD*)(addr + 0xA4), &addr, sizeof(addr), 0);
|
do

i will try but I do not understand.
I have to read the value of addr + A4 to get the final address and then I read the 24 bytes from that.

Addr : 0x00610053
is correct. You just need to read that last part as your string. 53 in hex is S which is what you needed.
