小弟在做一信息发送的程序时遇到一问题，它的描述如下： 1、在一个对话框中显示三个RichEdit控件。 2、初始化显示时显示给客户看到的是第二个RichEdit控件。也就是中间的这一个。 3、三个RichEdit控件的存局在开发环境中如同QQ的消息发送框一样。 4、当点击“显示模式”时，在第二个RichEdit的基础上显示出它布局上面的RichEdit控件。判断，如果是打开状态，再点击该按钮则恢复到初始状态. 5、点击“记录”时，在第二个RichEdit的基础上显示出它布局下面的RichEdit控件。判断，如果是打开状态，再点击该按钮则恢复到初始状态. 相信第五点在很多文章中都有介绍，可就是上述1-4的问题时让小弟困绕不已，经过查阅相关的Msdn资料，现将解决方案给大家一同参考，代码中可能有很多不成熟的地方，欢迎指正. 代码很简单，欢迎大家给小弟一些意见. -brother in a message sent to do the procedures encountered a problem, it is described as follows : one, in a dialog box shows three RichEdit control. 2, initialize the display to show customers see is the second RichEdit control.
