Getting 32 bit base address of program, without making a 64bit (only) program? - c++

Question

I'm making a Pixel-Cheat for a game. The program only works for 64bit currently and I'm trying to compile for 32bit.
I tried many ways of finding base address of process, but to no avail. Only the 64bit function works, and it will create a 64bit program.
Here's my 64bit working function:
DWORD64 GetModuleBase(HANDLE hProc, string &sModuleName)
{
HMODULE *hModules;
char szBuf[50];
DWORD cModules;
DWORD64 dwBase = -1;
//------
EnumProcessModulesEx(hProc, hModules, 0, &cModules, LIST_MODULES_ALL);
hModules = new HMODULE[cModules/sizeof(HMODULE)];
if(EnumProcessModulesEx(hProc, hModules,
cModules/sizeof(HMODULE), &cModules, LIST_MODULES_ALL)) {
for(int i = 0; i < cModules/sizeof(HMODULE); i++) {
if(GetModuleBaseName(hProc, hModules[i], szBuf, sizeof(szBuf))) {
if(sModuleName.compare(szBuf) == 0) {
dwBase = (DWORD64)hModules[i];
break;
}
}
}
}
delete[] hModules;
return dwBase;
}
All 32bit functions on google fails, with error:
21 59 C:\Users\Administrator\Documents\main.cpp [Error] cast from 'BYTE* {aka unsigned char*}' to 'DWORD {aka long unsigned int}' loses precision [-fpermissive]
How to get this code work in 32bit?

Answer 1

DWORD64 GetModuleBase(HANDLE hProc, string &sModuleName)
{
HMODULE *hModules;
char szBuf[50];
DWORD cModules;
DWORD64 dwBase = -1;
//------
EnumProcessModulesEx(hProc, NULL, 0, &cModules, LIST_MODULES_ALL);
hModules = new HMODULE[cModules/sizeof(HMODULE)];
if(EnumProcessModulesEx(hProc, hModules,
cModules/sizeof(HMODULE), &cModules, LIST_MODULES_ALL)) {
for(unsigned int i = 0; i < cModules/sizeof(HMODULE); i++) {
if(GetModuleBaseName(hProc, hModules[i], szBuf, sizeof(szBuf))) {
if(sModuleName.compare(szBuf) == 0) {
dwBase = (DWORD64)hModules[i];
break;
}
}
}
}
delete[] hModules;
return dwBase;
}
Your function as it stood compiled just fine in a 32bit exe on my machine with a few warnings which I corrected in the snippet above.
A few things you may want to do, is make sure your compiler is set to run in Multi-Byte Character Mode, and not Unicode if you're going to pass an 8bit char array(szBuf) to the function, otherwise use a 16bit wchar array. Also you passed hModules to EnumProcessModulesEx() on the first call which was where you were to get the number of modules, that would have generated an error since it has not yet been allocated, pass NULL on the first call to get the number of modules, then pass hModules.
Alas, the code should compile and run fine, but next time use GetModuleHandle() as mentioned before, will save you a headache.
