问题描述
我需要有关列表控件中某些问题的帮助.
我正在使用mfc的简单列表控件，我也想通过更改属性表及其完美工作来使其可编辑.
问题:我只想以这样一种方式来制作列表，使得列表控件中没有可用的重复数据.
注意:例如，我确实有一种解决方案，例如在事件LVN_ITEMCHANGED中将值存储在成员变量中，然后在事件LVN_ENDLABELEDIT中进行检查，如果发现数据已存在，则必须替换该值.由旧值控制列表.
问题:假设我确实编辑了一个项目并且不更改选择，然后再次单击进行编辑并输入了一些已经存在的值，那么倒数第二个而不是最后一个将被替换，这是因为LVN_ENDLABELEDIT事件不会被调用以获取最后一个值.
所以我需要某种帮助.
仅通过使用LVN_ENDLABELEDIT就有可能具有这种属性，并且我可以通过结构NMLVDISPINFO或LV_DISPINFO获得列表控件的旧值吗?
我不想使用LVN_BEGINLABLEEDIT事件，因为它每次我在item中编辑文本时都会调用.
谢谢
我自己:在该块上有个新孩子.
I need some help regarding some problem in my list control .
I am using simple list control of mfc also i want to make it editable which i did by changing in property sheet and its perfectly working.
Question: i just want to make list such a way that no duplicate data is available in the list control.
Note: i do have one solution for example i store the value before editing in a member variable in event LVN_ITEMCHANGED and later check in event LVN_ENDLABELEDIT and if it is found data already exist then i do have to replace the value of the list control by the old value.
ISSUE: Suppose i do edit an item and do not change the selection then again i click for editing and do enter some values which is already existing then the second last value will be replaced not the last one.It is because the LVN_ENDLABELEDIT event is not being called to get the last value.
So what i need some kind of help.
Is it possible to have such kind of property just by using LVN_ENDLABELEDIT and i can get the old value of list control by the structure NMLVDISPINFO or LV_DISPINFO?
I don''t want to use the LVN_BEGINLABLEEDIT event as it calls everytime i edit a text in item.
Thank you
me myself :D new kid on the block.
