Trouver le path d'un processus > code MSDN semble incorrect

J'ai tenter de retrouver cela grace a du code de MSDN mais ce code ne semble par fonctionner comme il faut car le .th32ModuleID de PROCESSENTREY32 semble toujours retourner null (0)

je me demandais si quelqu'un aurait un autre moyen

merci

le code de MSDN que je me suis servi est le suivant

#include <windows.h>
#include <tlhelp32.h>
#include <stdio.h>

BOOL GetProcessModule (DWORD dwPID, DWORD dwModuleID,
LPMODULEENTRY32 lpMe32, DWORD cbMe32)
{
BOOL bRet = FALSE;
BOOL bFound = FALSE;
HANDLE hModuleSnap = NULL;
MODULEENTRY32 me32 = {0};

// Take a snapshot of all modules in the specified process.

hModuleSnap = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, dwPID);
if (hModuleSnap == (HANDLE)-1)
return (FALSE);

// Fill the size of the structure before using it.

me32.dwSize = sizeof(MODULEENTRY32);

// Walk the module list of the process, and find the module of
// interest. Then copy the information to the buffer pointed
// to by lpMe32 so that it can be returned to the caller.

if (Module32First(hModuleSnap, &me32))
{
do
{
if (me32.th32ModuleID == dwModuleID)
{
CopyMemory (lpMe32, &me32, cbMe32);
bFound = TRUE;
}
}
while (!bFound && Module32Next(hModuleSnap, &me32));

bRet = bFound; // if this sets bRet to FALSE, dwModuleID
// no longer exists in specified process
}
else
bRet = FALSE; // could not walk module list

// Do not forget to clean up the snapshot object.

CloseHandle (hModuleSnap);

return (bRet);
}

BOOL GetProcessList ()
{
HANDLE hProcessSnap = NULL;
BOOL bRet = FALSE;
PROCESSENTRY32 pe32 = {0};

// Take a snapshot of all processes in the system.

hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);

if (hProcessSnap == (HANDLE)-1)
return (FALSE);

// Fill in the size of the structure before using it.

pe32.dwSize = sizeof(PROCESSENTRY32);

// Walk the snapshot of the processes, and for each process,
// display information.

if (Process32First(hProcessSnap, &pe32))
{
DWORD dwPriorityClass;
BOOL bGotModule = FALSE;
MODULEENTRY32 me32 = {0};

do
{
bGotModule = GetProcessModule(pe32.th32ProcessID,
pe32.th32ModuleID, &me32, sizeof(MODULEENTRY32));

if (bGotModule)
{

// Get the actual priority class.
hProcess = OpenProcess (PROCESS_ALL_ACCESS,
FALSE, pe32.th32ProcessID);
dwPriorityClass = GetPriorityClass (hProcess);
CloseHandle (hProcess);

// Print the process's information.
printf( "\nPriority Class Base\t%d\n",

printf( "PID\t\t\t%d\n", pe32.th32ProcessID);
printf( "Thread Count\t\t%d\n", pe32.cntThreads);
printf( "Module Name\t\t%s\n", me32.szModule);
printf( "Full Path\t\t%s\n\n", me32.szExePath);
}
}
while (Process32Next(hProcessSnap, &pe32));
bRet = TRUE;
}
else
bRet = FALSE; // could not walk the list of processes

// Do not forget to clean up the snapshot object.

CloseHandle (hProcessSnap);
return (bRet);
}
