ListView的表头变成这样是什么原因
--------------------编程问答--------------------
删除，再做。不行的话，代码上来看看。

--------------------编程问答-------------------- 还有两个名为sortascending.ico和sortdescending.ico 的图标帖不上去了，就是升序和降序的小箭头 --------------------编程问答-------------------- 不知道你是怎么操作的，你把它删了，再添加一个控件就行了 --------------------编程问答-------------------- 重新操作也是不行，程序运行到Header_SetImageList = SendMessage(hWnd, HDM_SETIMAGELIST, 0, ByVal himl)这一句，ListView就变成无限高了，不知道问题出在哪里 --------------------编程问答-------------------- 使用Microsoft Windows Common Controls 5.0就好了，我用的是6.0就出现这个问题
补充：VB , 基础类
