场景

1.有时候通过查询进程映像名称来判断某个程序是否在执行, 比如判断 adb.exe 是否正在运行, 从而不需要再次开启 adb进程; 或者某个服务是否开启, 比如AppleMobileDeviceService.exe 来判断是否启动了Apple移动设备服务, 从而提醒用户.

代码

1.如果查询的多个进程有存在的,即返回TRUE.

// test-process.cpp : 定义控制台应用程序的入口点。 // #include "stdafx.h" #include <Windows.h> #include <TlHelp32.h> #include <Shlwapi.h> #include <iostream> BOOL FailedBlacklist(WCHAR *wcBlacklist) { if(wcBlacklist == NULL) return FALSE; //make Copy WCHAR *wcBlacklistCopy = (WCHAR *) HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, (wcslen(wcBlacklist) + 2) * sizeof(WCHAR)); memcpy(wcBlacklistCopy, wcBlacklist, wcslen(wcBlacklist) * sizeof(WCHAR)); INT32 iBlacklistLen = wcslen(wcBlacklistCopy); for(INT32 iIterate = 0; iIterate < iBlacklistLen; iIterate++) { if(wcBlacklistCopy[iIterate] == L';') wcBlacklistCopy[iIterate] = 0x0000; } BOOL bProcessMatch = FALSE; //iterate list WCHAR *wcProcName = wcBlacklistCopy; while ((*wcProcName) && !bProcessMatch)//Go through each one until we hit a null. { //iterate processes HANDLE hProcessSnap = INVALID_HANDLE_VALUE; PROCESSENTRY32 pe32; hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPALL, 0); if(hProcessSnap == INVALID_HANDLE_VALUE) { if(wcBlacklistCopy != NULL) HeapFree(GetProcessHeap(), 0, wcBlacklistCopy); return FALSE; } pe32.dwSize = sizeof(PROCESSENTRY32); if(!Process32First(hProcessSnap, &pe32)) { if(wcBlacklistCopy != NULL) HeapFree(GetProcessHeap(), 0, wcBlacklistCopy); return FALSE; } do { if(PathMatchSpecW(pe32.szExeFile, wcProcName)) //Check to see if the current string matches the spec bProcessMatch = TRUE; }while(Process32Next(hProcessSnap, &pe32)); CloseHandle(hProcessSnap); if(!bProcessMatch) wcProcName += wcslen(wcProcName) + 1; } if(wcBlacklistCopy != NULL) HeapFree(GetProcessHeap(), 0, wcBlacklistCopy); return bProcessMatch; } int _tmain(int argc, _TCHAR* argv[]) { std::cout << FailedBlacklist(L"notepad.exe;chrome.exe") << std::endl; return 0; }
