从列表框中选择和取消选择 [英] Select and de-select from a list box

问题描述

我有4个相同形式的列表框和几个按钮，它们对列表中的选择执行操作。

任何人都可以帮忙????

在一个列表框中选择一个项目，您可以将其他项目传递给一个相当简单的功能，如下所示...

ClearOut List0

ClearOut List1

ClearOut List2

When an item is selected in one listbox, you can probably pass the others to a fairly simple function, something like this...
ClearOut List0
ClearOut List1
ClearOut List2
