如何动态更新ListView？ [英] How do I dynamically update a ListView?

问题描述

大家好，



我想在定时事件中将数据插入Listview，而不是通过按钮点击。这意味着在整个软件运行时，将不断添加和删除行。



如何进行此操作？我可以在创建ListView时添加行，例如

Hello All,

I'm looking to insert data into a Listview on a timed event rather than through a button click. This means that throughout the runtime of the software, rows will be continually added and deleted.

How do I go about doing this? I can add rows when I create the ListView e.g.

LVITEM lvi;
lvi.mask = LVIF_TEXT;
lvi.iItem = 0;
lvi.iSubItem = 0;
lvi.pszText = bob;

ListView_InsertItem(list, &lvi);

但我不知道哪个windows消息处理程序如果我想在飞行中更新，我需要把它放进去。例如。它会进入WM_PAINT吗？ WM_NOTIFY？等等。


我在没有MFC的情况下使用Win32 listview。



提前致谢！

But I don't know which windows message handler I would need to put this in if I wanted to update on-the-fly. E.g. does it go in WM_PAINT? WM_NOTIFY? Etc.

I'm using the Win32 listview without MFC.

Thanks in advance!

推荐答案

您可以在应用程序中的任何位置修改列表视图你知道 HWND 。所以在某处存储 HWND 并在你的计时器函数中使用它。

You can modify the list view from any point within your application when you know the HWND. So store the HWND somewhere and use it from within your timer function.
