c++ 运行cmd命令行

方法1：
 bool CreateProcessCommand(const wchar_t* szCMD)
 {
     TCHAR szCommand[MAX_PATH] = { 0 };
     wcscpy_s(szCommand, MAX_PATH, szCMD);    PROCESS_INFORMATION pi;
     STARTUPINFO si;
     ZeroMemory(&si, sizeof(si));
     si.cb = sizeof STARTUPINFO;
     si.wShowWindow = SW_HIDE;
     si.dwFlags = STARTF_USESHOWWINDOW /* | STARTF_USESTDHANDLES */;  // STARTF_USESTDHANDLES会导致lpCommandLine传递错误(原因未明)
     BOOL res = CreateProcess(
         NULL,
         szCommand,
         NULL,
         NULL,
         NULL,
         NORMAL_PRIORITY_CLASS,
         NULL,
         NULL,
         &si,
         &pi);
     if (res)
     {
         WaitForSingleObject(pi.hProcess, 2000);
         CloseHandle(pi.hProcess);
         CloseHandle(pi.hThread);
     }
     return true;
 }方法2：
WinExec(strCmdLine.c_str(), SW_HIDE);
