Hey,
| Code: |
DWORD dw, dw2;
HANDLE hProcessSnap;
HANDLE hProcess = NULL;
VirtualProtectEx(hProcess, (void *)0x1C9B57B3, sizeof(0x1C9B57B3), PAGE_EXECUTE_READWRITE, &dw);
PROCESSENTRY32 pe32;
hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
pe32.dwSize = sizeof(PROCESSENTRY32);
Process32First(hProcessSnap, &pe32);
do
{
if(!strcmp(pe32.szExeFile, "deadrising2.exe"))
{
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID);
break;
}
}
while(Process32Next(hProcessSnap, &pe32));
CloseHandle( hProcessSnap );
if(hProcess != NULL)
{
WriteProcessMemory(hProcess, (void *)0x1C9B57B3, "DR2MP", sizeof(0x1C9B57B3), NULL);
CloseHandle(hProcess);
return true;
}
|
And I've also tried:
| Code: |
DWORD dw, dw2;
VirtualProtect((void *)0x1C9B57B3, sizeof(0x1C9B57B3), PAGE_EXECUTE_READWRITE, &dw);
strcpy((void *)0X1C9B57B3, "DR2MP", sizeof(0x1C9B57B3));
VirtualProtect((void *)0x1C9B57B3, sizeof(0x1C9B57B3), dw, &dw2);
|
Problem is, i can change that address in cheat engine and the button text changes to DR2MP, but when i try it in C++ it just refuses to change?
Any ideas why this wont work?
Please help if you can, thanks!

Virtually every one of those functions has the possibility of failing, yet you aren't doing any error-checking whatsoever. You're calling virtual protect on an uninitialized process handle, you're probably passing the wrong value for the size parameter of writeprocessmem, and you're possibly failing by asking for process_all_access instead of more granular permissions. There might be more, dunno. I'd scrap what you have and google for some better examples.
Cheers,

| What the heck does 'sizeof(0x1C9B57B3)' even resolve to ?

Alright,
I fixed up my code, but yet she still doesnt work 
Here's what i have atm:
| Code: |
bool CMemory::InstallStringPatch(DWORD address, const char * string, int size)
{
DWORD dw;
HANDLE hProcessSnap;
HANDLE hProcess = NULL;
PROCESSENTRY32 pe32;
hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
pe32.dwSize = sizeof(PROCESSENTRY32);
Process32First(hProcessSnap, &pe32);
do
{
if(!strcmp(pe32.szExeFile, "deadrising2.exe"))
{
hProcess = OpenProcess(PROCESS_VM_WRITE, FALSE, pe32.th32ProcessID);
break;
}
}
while(Process32Next(hProcessSnap, &pe32));
CloseHandle(hProcessSnap);
if(hProcess != NULL)
{
VirtualProtectEx(hProcess, (void *)address, size, PAGE_READWRITE, &dw);
WriteProcessMemory(hProcess, (void *)address, string, size, NULL);
CloseHandle(hProcess);
MessageBox(0, "WROTE TO THE ADDRESS", "it wrote", NULL);
return true;
}
return true;
}
|
Now when i call it, i do get the message box, but there has got to be something wrong as it does not change the value, but i cannot pinpoint what?
| Code: |
m_pCMemory->InstallStringPatch(BUTTON_MENU_START, "DR2MP", 5);
|
Is how i call it.
Anyone know why still?

| Dude, check your return values for errors. Writeprocessmem is probably failing because you still don't have the correct permissions.
