崔占民在其文章《用代码实现ListView控件的行间隔颜色》中给出了实现代码，经过笔者测试，发现有如下bug：
首先，虽然可以看到背景色间隔，但是条块的高度等于原始picGreenBar的高度。应该在autoredraw属性设置为true之前，将height属性设置为一个最小值，比如1。
另外，listview的属性要修改一下： ... ListView1.View = lvwReport ListView1.FullRowSelect = True ListView1.GridLines = True picGreenbar.Height = 1 '添加一些实验数据 ....
为方便读者，将全部代码公布如下（关键代码来自《用代码实现ListView控件的行间隔颜色》）：
