结果如下，你可以看到行和行间的颜色的交错显示，多酷，而这只需要两个if的判断就可以做到了。

1. 在ListCtrl控件绘画前处理NM_CUSTOMDRAW消息。
2. 告诉Windows我们想对每个Item处理NM_CUSTOMDRAW消息。
3. 当这些消息中的一个到来，告诉Windows我们想在每个SubItem的绘制前处理这个消息
4. 当这些消息到达，我们就为每个SubItem设置文字和背景的颜色。

1. 对ListCtrl在“绘画前”处理NM_CUSTOMDRAW消息。
2. 告诉Windows我们想在每个Item被画的时候获得NM_CUSTOMDRAW消息。
3. 当这些消息来临，告诉Windows我们想在你画完的时候获取NM_CUSTOMDRAW消息。
4. 当这些消息来到的时候，我们就重新画每一个Item的图标。
