Windows界面编程第八篇 listbox彩色显示隔行变色

在CSDN论坛上看到很多询问如何设置listbox的颜色，如何让listbox隔行变色等等。因此专门写了一篇《Windows界面编程第八篇
listbox彩色显示隔行变色》来为大家解惑。
首先看看下图（如果看不到，可以通过地址http://blog.csdn.net/morewindows/article/details/8656061访问）。
要设置listbox的颜色及让listbox隔行变色主要是通过处理WM_DRAWITEM消息，这个消息在MSDN的解释如下：
The
WM_DRAWITEM message is sent to the parent window of an owner-drawn button, combo box, list box, or menu when a visual aspect of the button, combo box, list box, or menu has changed.
通过这个消息最主要可以得到一个DRAWITEMSTRUCT类型的结构体。这个结构体的原型如下：
//By MoreWindows-(http://blog.csdn.net/MoreWindows)
typedef structtagDRAWITEMSTRUCT {
UINTCtlType;
UINTCtlID;
UINTitemID;
UINTitemAction;
UINTitemState;
HWNDhwndItem;
HDChDC;
RECT
rcItem;
ULONG_PTRitemData;
}DRAWITEMSTRUCT;
这个结构体比较复杂，功能也很强大。全部记住它的功能是不必要的。因此直接查看下如何设置listbox的颜色，如何让listbox隔行变色这两个功能是如何完成的即可。完整代码+注释如下（可以直接到http://download.csdn.net/detail/morewindows/5128660（免积分）下载）。
