说我有以下代码,syscall用于隐藏命令行窗口

process := exec.Command(name, args...)
process.SysProcAttr = &syscall.SysProcAttr{HideWindow: true}
err := process.Start()
if err != nil {
    log.Print(err)
}

但是当我编译它并尝试在Windows中运行它时,命令行窗口再次出现

我该怎么做才能防止命令行窗口出现？

PS我已经知道如何使用golang源编译成Windows GUI可执行文件go build -ldflags -H=windowsgui,但这样做只能确保程序本身不会Exec显示命令行窗口,无论如何都会显示那些窗口

每当我尝试读取UTF-8编码的文本文件时,即使使用open(file_name, encoding='utf-8'),我总是会收到错误,说ascii编解码器无法解码某些字符(例如,使用时for line in f: print(line))

和locale命令打印:

strings.Contains(str_to_check, substr)只需要一个参数作为要检查的子字符串,如何在不strings.Contains()重复使用的情况下检查多个子字符串？

例如. strings.Contains(str_to_check, substr1, substr2)

我正在Arch Linux上安装nokogiri 1.6.6.2,因为如果没有它,metasploit安装就无法继续.我得到以下输出:

我希望我的程序检查Windows 10是否已被激活

我有以下代码

 public static bool IsWindowsActivated()
    {
        bool activated = true;
        ManagementScope scope = new ManagementScope(@"\\" + System.Environment.MachineName + @"\root\cimv2");
        scope.Connect();

        SelectQuery searchQuery = new SelectQuery("SELECT * FROM Win32_WindowsProductActivation");
        ManagementObjectSearcher searcherObj = new ManagementObjectSearcher(scope, searchQuery);

        using (ManagementObjectCollection obj = searcherObj.Get())
        {
            foreach (ManagementObject o in obj)
            {
                activated = ((int)o["ActivationRequired"] == 0) ? true : false;
            }
        }
        return activated;
    }

当试图使用这段代码时,调试器会抱怨Invalid class,我不知道它是什么

我该怎么做才能解决这个问题？或者有没有其他方法来检查Windows的许可证状态？
