Window：进程操作

1、获取当前进程名称

TCHAR szFileFullPath[256]; ::GetModuleFileName(NULL, static_cast<LPTSTR>(szFileFullPath), 256); tstring wstrProcessName(szFileFullPath); if (!wstrProcessName.empty()) { int nPos = wstrProcessName.find_last_of(_T('\\')); int nLen = wstrProcessName.length(); wstrProcessName = wstrProcessName.substr(nPos + 1,nLen); }

2、在System权限降权读取appdata目录。

TCHAR wszAppDataPath[MAX_PATH * 2] = { 0 }; ::SHGetSpecialFolderPath(NULL, wszAppDataPath, CSIDL_APPDATA, TRUE); HANDLE hToken = NULL; if(true == ImpersonateLoggedOnUserWrapper(hToken)) { if (S_OK == SHGetFolderPath(NULL, CSIDL_APPDATA, hToken, SHGFP_TYPE_DEFAULT, wszAppDataPath)) { //使用完毕之后通过调用RevertToSelf取消模拟 RevertToSelf(); } } //对当前用户权限降权以普通用户执行 bool ImpersonateLoggedOnUserWrapper(HANDLE& hToken) { DWORD dwConsoleSessionId = WTSGetActiveConsoleSessionId(); if (WTSQueryUserToken(dwConsoleSessionId, &hToken)) { if (ImpersonateLoggedOnUser(hToken)) { return true; } } return false; }

3、判断进程是否存在

bool FindProcess(std::wstring wstrExeName) { PROCESSENTRY32 my; HANDLE l = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); if (((int)l) != -1) { my.dwSize = sizeof(my); if (Process32First(l, &my)) { do { _tcsupr(my.szExeFile); if (_tcsicmp(my.szExeFile, wstrExeName.c_str()) == 0) { CloseHandle(l); return true; } } while (Process32Next(l, &my)); } CloseHandle(l); } return false; }

4、启动指定的进程，隐藏进程窗口

//path：启动的进程路径 PROCESS_INFORMATION pi; STARTUPINFOW si; //隐藏进程窗口,启动进程 si.cb = sizeof(STARTUPINFOW); si.lpReserved = NULL; si.lpDesktop = NULL; si.lpTitle = NULL; si.dwFlags = STARTF_USESHOWWINDOW; si.wShowWindow = SW_HIDE; si.cbReserved2 = NULL; si.lpReserved2 = NULL; pi.hProcess = NULL; BOOL ret = CreateProcessW(NULL, (LPWSTR)path.c_str(), NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi); HANDLE hProcess = pi.hProcess; if (hProcess != 0) { CloseHandle(hProcess); }

5、以管理员权限启动指定的进程，隐藏进程窗口

//wstrPath：进程的本地路径 //nShowType：窗口的展示类型，SW_SHOW or SW_HIDE //wstrDirectory：文件目录，可为空 //wstrParam：启动进程所带的传参 SHELLEXECUTEINFO sei = { sizeof(SHELLEXECUTEINFO) }; sei.fMask = SEE_MASK_NOCLOSEPROCESS; sei.lpVerb = TEXT("runas"); sei.lpFile = wstrPath.c_str(); sei.lpDirectory = wstrDirectory.c_str(); sei.nShow = nShowType; sei.lpParameters = wstrParam.c_str(); if (!ShellExecuteEx(&sei)){ return false； }
