When starting with protocols that work at the upper layers of the network models, each set of data is wrapped inside the next lower layer protocol, similar to wrapping letters inside an envelope. The application creates the data, then the transport layer wraps that data inside its format, then the network layer wraps the data, and finally the link (Ethernet) layer encapsulates the data and transmits it. Each network layer either encapsulates the data stream with additional information, or manages data handling or come part of the connection

Color ListCtrl Report List
使用CListCtrl控件的过程中,我们会发现使用及其不方便,特别是在使用“report"显示模式时, 想给指定条目添加背景颜色,CListCtrl控件所提供的设置颜色函数只能使得控件的界面变得好看一些,根本不能满足我们的要求,我们无法把特定的一项或几项添加上不同的颜色以示区别。 幸运的是很多VC的使用者在改造CListCtrl类,使之更加功能强大上做了很多工作,开发出了各种各样的继承类来实现这个功能,Sven Freitag 就是其中的一员。他开发出了CListCtrl的继承类CColorListCtrl来实现给指定的条目加背景色的功能,并无偿的在网上公布给VC的使用者,我在源代码中收集了他的源程序,各位读者可以先阅读学习一下。
