通过删除节点，可以删除相映的记录，包含带子节点的节点(by removing nodes can be removed form a contrast to the record, including scallops of nodes)

通过拖拉树型控件CTreeCtrl的节点来改变同一层次上节点的位置顺序-Through drag and drop tree control CTreeCtrl node to change the same level, the location of the node sequence

TreeView控件来显示，它是用树结构来做项目的。

实现CtreeCtrl控件多选功能的封装类(Suport multiselection functionality for tree controls.)

说明：  A simple example of audio communication, using a full-duplex mode of communication,

treeview控制展示，實做item的樹狀結構。(TreeView control to display, it is the tree structure to do item.)

在CRichEditCtrl控件中我们不能得到这样的操作，同时CRichEditCtrl是能够包含各种格式的内容，就好像Word一样能够写入各种不同的字体，不过CRichEditCtrl没有给我们提供这样的要求，今天我的目的也就是给他添加这样的扩展操作.-in Hyperlink control, we do not get the operation, while Chars can include various types of content, it seems like Microsoft Word to write different kinds of fonts, but Chars not provided us with such a request, my aim is to add to his expansion of the operation.

1、异步操作方式。设备连接和短信发送均采用异步方式，即容器程序调用连接函数或发送函数后立即返回。由控件自行完成连接或发送过程，当操作完成后，将执行结果以事件的形式通知容器程序。 2、内部包含收发缓冲队列。控件可以同时接受容器程序较多的发送请求，控件将这些发送请求放到一个发送队列中，控件依次逐个执行该发送队列，并将执行结果以事件的形式通知容器程序。控件包括了内部发送队列和内部接收队列，并且提供了队列的处理情况的访问方法，根据这个特性，容器程序可以连续提交多个短信发送请求； 3、支持多个控件并行工作。在一个程序中使用可以使用多个短信控件（即同时连接多个GSM Modem设备）时，如果要发送一条短信，容器程序可优先选择发送队列为空的短信控件发送，或者选择发送队列中剩余发送条数最少的短信控件发送。 -1, asynchronous mode of operation. Connectivity and equipment were used to send messages asynchronous modes, namely containers Invoking connecting function or sent immediately after the function returns. By linking its own control or sent to the process, when the operation is completed, the results will be implemented in the form of Vessel notification procedures. 2, the internal transceiver contains a buffer queue. Controls can also accept containers of this process more requests, these controls will be placed in a request sent this cohort, the controls were sent individually to implement the queue, and will result in the implementati
