most of modules turn to a failure in getting file path :( – jondinham Aug 29 '11 at 4:20

Does it work when called from a 32bit environemet to get PID of a 64bit process ? I face problem and had to use QueryFullProcessImageName instead of GetModuleFileNameEx – philippe lhardy Nov 13 '14 at 17:55
Call OpenProcess
to get a handle to the process associated with your PID. Once you have a handle to the process, call GetModuleFileNameEx
to get its fully-qualified path. Don't forget to call CloseHandle
when you're finished using the process handle.
Here's a sample program that performs the required calls (replace 1234 with your PID):
#include <windows.h>
#include <psapi.h> // For access to GetModuleFileNameEx
#include <tchar.h>
#include <iostream>
using namespace std;
#ifdef _UNICODE
#define tcout wcout
#define tcerr wcerr
#else
#define tcout cout
#define tcerr cerr
#endif
int _tmain(int argc, TCHAR * argv[])
{
HANDLE processHandle = NULL;
TCHAR filename[MAX_PATH];
processHandle = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, 1234);
if (processHandle != NULL) {
if (GetModuleFileNameEx(processHandle, NULL, filename, MAX_PATH) == 0) {
tcerr << "Failed to get module filename." << endl;
} else {
tcout << "Module filename is: " << filename << endl;
}
CloseHandle(processHandle);
} else {
tcerr << "Failed to open process." << endl;
}
return 0;
}
