当然，只需编写几个函数来添加和删除数组中的内容。

Sure, just write a couple of functions to add and remove things in an array.

您还可以使用未排序的ListBox作为队列，


要添加：

List1.AddItem" ABCD" ，0

''这个添加到顶部


到PopOut最后一项：

str1 = List1.List（List1.ListCount -1）

List1.RemoveItem List1.ListCount-1

与Killer建议的数组相同。

但是使用ListBox很容易，你不必遍历所有项目以向下推，只需将AddItem置于0，确保其他Listitems被推下。

Hi,

You can also use non-sorted ListBox as a Queue,

To Add :
List1.AddItem "ABCD", 0
''This Adds on Top

To PopOut Last item :
str1 = List1.List(List1.ListCount-1)
List1.RemoveItem List1.ListCount-1

Same thing you can do with array as Killer suggested.
But ease with ListBox is, you don''t have to loop through all the items to Push Down, just AddItem at 0, ensures, other Listitems are pushed down.

您好，您也可以使用未排序的ListBox作为队列...

Hi, You can also use non-sorted ListBox as a Queue ...

您必须使用数组或指针进行队列操作。控件不是更好的例子（当然我们可以实际使用）。但从逻辑上讲，在Listbox中我们可以使用索引值从列表中间删除项目，并更改下一个索引的值，该值不应该发生在队列（FIFO）中。

You have to use Array or pointer for Queue operation. Controls will not be a better example (of course we can use practically). But logically, in Listbox we can remove items from the middle of list using index value and change value for next index which should not happen in queue (FIFO).
