首先再前面特别啰嗦几句，  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzM2MDcwNw_size_16_color_FFFFFF_t_70]  
对于这个界面，有两个比较重要的控件为：  
![在这里插入图片描述][20200714193209782.png]  
获取IP  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzM2MDcwNw_size_16_color_FFFFFF_t_70 1]

UpdateData(TRUE);
    	CString DeviceIp;
    	BYTE nField0,nField1,nField2,nField3; 
    	m_ctrlDevIp.GetAddress(nField0,nField1,nField2,nField3);
    	DeviceIp.Format("%d.%d.%d.%d",nField0,nField1,nField2,nField3);

如此就可以获取到IP了，然后再根据实际情况转换为点分十进制。  
最中间播放的框，![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzM2MDcwNw_size_16_color_FFFFFF_t_70 2]  
类型都是static Text。  
播放视频，只要获取到大框的句柄就可以了：

除此之外，我们可以看到，可以设置该按钮的文字。

//------------------------------------------  
重点，重点，重点  
现在说说按钮的按下和抬起对应的事情。比如说按钮按下云台开始转动，抬起，云台停止转动，按下和抬起对应两个事件，但是一般正常我们在login中只能捕捉到一个事件，那该这么做呢。不要着急，且看下面：  
首先创建button控件变量，也就是选择Control  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzM2MDcwNw_size_16_color_FFFFFF_t_70 4]  
注意，上面我们是自定义控件，对cbutton进行了改写。具体步骤如下，

这个自定义的PTZButton继承了CButton

这里定义接收两个消息：  
![在这里插入图片描述][20200714195349241.png]  
首先，初始化

CPTZButton::CPTZButton()
    { 
    	m_iSubBtnIndex = g_iPtzBtnIndex++;
    	m_lPlayHandle  = -1;
    }

这里，每个button在初始化的时候都会自动+1，通过全部变量控制。

通过，switch–case 就可以控制了。  
很简单有木有。核心，重写控件，控件编号，另外对于PTZButton定义顺序和case的不能错
