一个MFC类的子类，方便大家使用，画的不好，希望见量，LIST的样子和OD差不多，很多东西都可以实现了，比起原版的要强大些，实际一个不难的东西，google找到的X站，是需要会员可以下的，会员注册是需要RMB的，无法偷懒，只有自己动手。

//关键重画部分已经使用类虚拟函数,如果需要那部分重画,直接子类化重载,将绘画部分和重载分开,方便做默认处理^^.
//LVS_OWNERDATA属性似乎无法用代码开启,似乎是在控件创建时设定,但是当在对话框初始化函数中时,控件已经创建完成,
//所以,在使用的时候需要手动开启CListCtrl控件的该属性.

1楼太高，说明贴2楼。
单元格颜色可以设置，正行颜色也可以设置，焦点颜色和是否出现也可以设置，根据喜欢可以设置为网格线为横或纵或横纵，网格线横纵颜色也可以分开设置。 这此新加了多行处理，需要在创建控件的时候选上OWNERDATA属性。 使用vl开头的函数就可以了，无需重载任何消息，我已经画好了。 整体使用vector来存储数据，但是由于vector速度快，提高了速度，占用内存大了点。 新加了个自定义函数，方便大家拿去自己加东西，加完后，根据情况更新一下数据。 比如像OD里的连接线就可以加在这个函数里。 说明结束，给需要的人一个方便，如果觉得不好，就路过好了  如有与本版不否，请斑竹移一下，谢谢. |

提两个问题.....大量插入数据速度如何? 绘画有设定重绘的范围么? 楼主能发个效果图最好了..........微软給的半成品的东西就是累人........支持楼主改进.....

 打包方便大家下载

速度比较快插入50W行我电脑就几秒。。。
我电脑不好，电脑好的速度会更快点，插入数据的时候把最后一个项目设置为FALSE，最后插入完了，再设置插入行。。。 不多说了闪了。。 代码给出来了自己看看，效果就不用贴了。。 把OD打开，和OD几乎差不多，我是按OD做的.

折腾不出来。。。楼主有空发个 demo 工程吧。。。。在 owner data 属性下 怎么改变 颜色一直没弄好。。。。

 用了下..我只能弄成这样..感觉有些函数没有实现.... 不过还是不错....
