Hi,

I am developing an application using MFC, based on List Control CListCtrl. I have to get the list of items selected in that list control. I found the way to do. It is like linear search. Going through each item and checking for selection.

This has serious performance issue if the number of rows in the list control goes up. Is there any other way to speed up the process of finding the selected items.


Thanks,

推荐答案

如果为CListCtrl，请使用GetFirstSelectedItemPosition和GetNextSelectedItemPosition.这不是线性搜索；您只遍历选定的项目，而不遍历整个列表.请参阅 http://msdn.microsoft.com/zh-CN/library/zdff988k(v = VS.80).aspx [

If this is CListCtrl, use GetFirstSelectedItemPosition and GetNextSelectedItemPosition. This is not linear search; you only traverse selected items, not the whole list. See http://msdn.microsoft.com/en-US/library/zdff988k(v=VS.80).aspx[^].
