As Duoas said, the functions I provided require the name of the actual window. If you were looking for how to check against "process.exe" then this should help you

Kod:: #include <iostream> #include <string> #include <windows.h> #include <tlhelp32.h> DWORD FindProcessId(const std::wstring& processName); int main() { std::wstring processName; std::wcout << "Enter the process name: "; std::getline(std::wcin, processName); DWORD processID = FindProcessId(processName); if ( processID == 0 ) std::wcout << "Could not find " << processName.c_str() << std::endl; else std::wcout << "Process ID is " << processID << std::endl; system("PAUSE"); return 0; } DWORD FindProcessId(const std::wstring& processName) { PROCESSENTRY32 processInfo; processInfo.dwSize = sizeof(processInfo); HANDLE processesSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL); if ( processesSnapshot == INVALID_HANDLE_VALUE ) return 0; Process32First(processesSnapshot, &processInfo); if ( !processName.compare(processInfo.szExeFile) ) { CloseHandle(processesSnapshot); return processInfo.th32ProcessID; } while ( Process32Next(processesSnapshot, &processInfo) ) { if ( !processName.compare(processInfo.szExeFile) ) { CloseHandle(processesSnapshot); return processInfo.th32ProcessID; } } CloseHandle(processSnapshot); return 0; }

Found this while helping someone else, hope it helps you. It's written by someone called Irwin.

Kod:: #include <psapi.h> #define MAX_PROCESSES 1024 DWORD FindProcess(__in_z LPCTSTR lpcszFileName) { LPDWORD lpdwProcessIds; LPTSTR lpszBaseName; HANDLE hProcess; DWORD i, cdwProcesses, dwProcessId = 0; lpdwProcessIds = (LPDWORD)HeapAlloc(GetProcessHeap(), 0, MAX_PROCESSES*sizeof(DWORD)); if (lpdwProcessIds != NULL) { if (EnumProcesses(lpdwProcessIds, MAX_PROCESSES*sizeof(DWORD), &cdwProcesses)) { lpszBaseName = (LPTSTR)HeapAlloc(GetProcessHeap(), 0, MAX_PATH*sizeof(TCHAR)); if (lpszBaseName != NULL) { cdwProcesses /= sizeof(DWORD); for (i = 0; i < cdwProcesses; i++) { hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, lpdwProcessIds[i]); if (hProcess != NULL) { if (GetModuleBaseName(hProcess, NULL, lpszBaseName, MAX_PATH) > 0) { if (!lstrcmpi(lpszBaseName, lpcszFileName)) { dwProcessId = lpdwProcessIds[i]; CloseHandle(hProcess); break; } } CloseHandle(hProcess); } } HeapFree(GetProcessHeap(), 0, (LPVOID)lpszBaseName); } } HeapFree(GetProcessHeap(), 0, (LPVOID)lpdwProcessIds); } return dwProcessId; }
