c++ 无弹窗执行cmd命令

void prompt(LPWSTR szCmd) {
    TCHAR szModuleName[MAX_PATH];
    STARTUPINFO si = { 0 };
    PROCESS_INFORMATION pi = { 0 };

    GetModuleFileName(NULL, szModuleName, MAX_PATH);

    CreateProcess(NULL, szCmd, NULL, NULL, FALSE, CREATE_NO_WINDOW, NULL, NULL, &si, &pi);

    WaitForSingleObject(pi.hProcess, INFINITE);

    CloseHandle(pi.hThread);
    CloseHandle(pi.hProcess);
}

使用方法：

WCHAR cmd[] = { L"ping www.baidu.com"  };
prompt(cmd);

注意事项：阻塞方法

 

////////////////////////////////////关于CreateProcess////////////////////////////////////

BOOL CreateProcessW(
  [in, optional]      LPCWSTR               lpApplicationName,
  [in, out, optional] LPWSTR                lpCommandLine,
  [in, optional]      LPSECURITY_ATTRIBUTES lpProcessAttributes,
  [in, optional]      LPSECURITY_ATTRIBUTES lpThreadAttributes,

  [in]                DWORD                 dwCreationFlags,
  [in, optional]      LPVOID                lpEnvironment,
  [in, optional]      LPCWSTR               lpCurrentDirectory,

  [out]               LPPROCESS_INFORMATION lpProcessInformation
);

//lpApplicationName： 要执行的应用名称，可以是 完整的路径+应用名称
//例如：
WCHAR  moduleName[] = { L"C:\\Windows\\System32\\cmd.exe" };

//也可以是仅应用名称，如果是应用名称，则系统会使用当前执行的exe的 磁盘盘符+文件目录 来补全路径，且应用名称必须包含后缀名

//lpApplicationName 可以为NULL， 如果为NULL，moduleName必须以 moduleName+空格的形式 添加到lpCommandLine 参数前面

执行cmd并获取输出：
