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; }
