Process ID

[Opwar]

How do you find a programs Process ID?

[David Crow]

How about GetCurrentProcessId()?

That depends on the kind of data you already have. Is it the current process? Or do you have the name of the executable? Or a window handle? Jens

[Opwar]

Yeah the name is armyops.exe

Depending on your operating system you can use - the PSAPI functions (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/perfmon/base/process_status_helper.asp) - or the ToolHelp functions (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/perfmon/base/tool_help_library.asp) Jens

If you have the name of the process, and that process is not you, you must either search for a window you know that process created, and get the process ID from that, or, if you only have the name of the process, you need to use the PSAPI/ToolHelper API to enumerate all running processes, look at each one's name, check if it matched, and if so, grab it's process ID. See here http://msdn.microsoft.com/library/default.asp?url=/library/en-us/perfmon/base/about\_psapi.asp Bare in mind PSAPI only works with NT/2k/XP so if you want a cross platform soulition, use ToolTip - see the file Tlhelp32.h in the platform SDK for a statring point- but you want something like this which terminates a process given a name BOOL CTestEnvKillerApp::InitInstance() { // check which o/s OSVERSIONINFO osvi; memset(&osvi, NULL, sizeof(OSVERSIONINFO)); osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); GetVersionEx(&osvi); if (osvi.dwPlatformId == VER_PLATFORM_WIN32_NT) // NT { // load the process status helper library HMODULE hLib = LoadLibrary( _T("psapi.dll") ); if (NULL == hLib) { AfxMessageBox(_T("Could not load PSAPI.DLL.\nPlease check it's in your path"), MB_OK | MB_ICONEXCLAMATION); return FALSE; } // get the functions lpfnEnumProcesses pFnEnumProc = (lpfnEnumProcesses)GetProcAddress( hLib, "EnumProcesses" ); lpfnGetModuleBaseName pFnGetModBaseName = (lpfnGetModuleBaseName)GetProcAddress( hLib, "GetModuleBaseNameA" ); lpfnEnumProcessModules pFnEnumProcMod = (lpfnEnumProcessModules)GetProcAddress( hLib, "EnumProcessModules" ); if ( (NULL == pFnEnumProc) || (NULL == pFnGetModBaseName) || (NULL == pFnEnumProcMod) ) { AfxMessageBox(_T("Could not find procedure in PSAPI.DLL"), MB_OK | MB_ICONEXCLAMATION); FreeLibrary(hLib); return FALSE; } DWORD dwNeeded = 0; DWORD dwProcessIDs[1024]; memset(dwProcessIDs, NULL, sizeof(DWORD)*1024); // get all the process IDs if ( pFnEnumProc(dwProcessIDs, 1024, &dwNeeded) ) { char szProcessName[MAX_PATH]; short sNumProcs = (short)( dwNeeded/sizeof(DWORD) ); for (short s = 0; s < sNumProcs; s++) { memset(szProcessName, NULL, sizeof(char)*MAX_PATH); // get the handle HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ | PROCESS_TERMINATE, FALSE, dwProcessIDs[s] ); if (hProcess) { HMODULE hMod = NULL; dwNeeded = 0; // retrieve handle if ( pFnEnumProcMod( hProcess, &hMod, sizeof(hMod), &dwNeeded) ) {
