取消选择列表框中的项目（如何？） [英] Unselecting items in a Listbox (HOW?)
问题描述
嗨。
有没有办法取消选择列表框中的项目，以编程方式？
这就是我想要做的事情（我一直在努力做到这一点
调试
表格，但我没有成功）...
我有一个带有两个列表框的表格。
另外，在选项组中有两个选项按钮：1个按钮用于
第一个
列表框和1个用于otgher列表框的按钮。我们的想法是选择一个
选项按钮来启用相关的列表框。这个工作只是
罚款。但是...
假设用户选择了按钮1并启用了第一个列表框。
然后他们在第一个列表框中选择了几个项目。
然后他们决定（在点击命令按钮之前生成
查询 - 这是表单的目的）他们真正想要使用
第二个列表框。因此，他们点击
其他选项按钮，这将禁用列表框1并启用列表框2.
但是，在列表框1中选择的项目仍然是
突出显示。我希望突出显示那些突出显示的项目
（未选中）。
任何想法？
问候，
SueB

Hi.
Is there a way to "unselect" items in a listbox, programmatically?
Here''s what I want to do (and I''ve been trying to to this while
debugging
the form, but I''ve been unsuccessful) ...
I have a form with two listboxes.
The form, also, has two option buttons in an options group: 1 button for
the first
listbox and 1 button for the otgher listbox. The idea is to select an
optionbutton to enable the associated listbox. This is working just
fine. However ...
Let''s say the user selects optionbutton 1 and enables the first listbox.
Then they select a few items in the first listbox.
Then they decide (before hitting the command button to generate the
query - which is the purpose of the form) that they really want to use
the 2nd list box. So, they hit the
other option button, which will disable listbox 1 and enable listbox 2.
However, the items that were selected in listbox 1 are still
highlighted. I want to get those highlighted items unhighlighted
(unselected).
Any ideas?

SueB

对于多选列表框，我相信一种方法是重新分配
行源
me！lstList .rowsource = me！lstList.rowsource
否则我认为你可以循环列表，并设置每个项目
for l = 0 to我！lstList.listcount-1
me！lstList.selected（l）= false
next l

For multiselect listboxes, I believe one way is to reassigning the
rowsource
me!lstList.rowsource = me!lstList.rowsource
Else I think you could loop the list, and set each item
for l = 0 to me!lstList.listcount-1
me!lstList.selected(l) = false
next l
--

试试这个（适当修改以适合你的代码）：
Private Sub btnUseList2_Click（）
Dim lngLoop As Long
lst1 .Enabled = False
对于lngLoop = 0到lst1.ItemsSelected.Count - 1
lst 1.Selected（lst1.ItemsSelected.Item（lngLoop））= False
下一个lngLoop
lst2.Enabled = True
End Sub
当单击启用第二个列表框的按钮时，将运行此代码;它
执行以下操作：
1）禁用第一个列表框
2）循环显示第一个列表框中的项目，选择任何
选择
3）启用第二个列表框
希望这会有所帮助！

SueB写道：
Sue -
Try this (modified appropriately to fit your code):
Private Sub btnUseList2_Click()
Dim lngLoop As Long
lst1.Enabled = False
For lngLoop = 0 To lst1.ItemsSelected.Count - 1
lst1.Selected(lst1.ItemsSelected.Item(lngLoop)) = False
Next lngLoop
lst2.Enabled = True
End Sub
This code is run when the button to enable the second list box is clicked; it
does the following:
1) Disables the first list box
2) Cycles through the items in the first list box, de-selecting any that are
selected
3) Enables the second list box
Hope this helps!
