一、Win10环境的配置

1、Win10-我的电脑-属性-远程桌面-开启

2、打开控制面板-管理工具（Win11是【Windows工具】）-本地安全策略-安全选项

账户：使用空密码的本地账户只允许进行控制台登录

根据你的需要选择启用或禁用，如果要被远程的电脑没有设置开机密码，那么请选择【禁用】，然后务必重启电脑才能生效！！

或者Windows-开始菜单-运行：

输入secpol.msc或者gpedit.msc也能打开，本地策略，安全选项

二、Qt工程

1、pro文件

QT += axcontainer

2、 ui文件

在ui上拖放控件：QAxWidget控件，右键设置控件： Microsoft RDP Client Control - version 12

3、源码

#include "formrdp.h"
#include "ui_formrdp.h"#include 
#include FormRDP::FormRDP(QWidget *parent): QWidget(parent),ui(new Ui::FormRDP)
{ui->setupUi(this);init();
}FormRDP::~FormRDP()
{delete ui;
}void FormRDP::init()
