我遇到了一些问题,无法将重复项添加到Excel中的列表框中。我有两个列表框,lstBoxSurveyList和lstBoxSurveyRemove。我正在尝试从lstBoxSurveyList添加项目,但前提是它不在lstBoxSurveyRemove中。我的代码在下面(只需对其进行编辑)。有什么建议么?我在VB.Net上看到了一些帖子,但是它们似乎在Excel中不起作用。
Dim i As Integer
For i = 0 To lstBoxSurveyRemove.ListCount - 1
If lstBoxSurveyRemove.List(i) = lstBoxSurveyList.Value Then
MsgBox ("This value exists")
Else
lstBoxSurveyRemove.AddItem (lstBoxSurveyList.Value)
End If
Next i
答案 0 :(得分:1)
您必须等到循环完成后才能添加项目,否则,您只是在检查第一个项目是否匹配。
类似这样的东西:
Dim i As Long, bFound As Boolean
For i = 0 To lstBoxSurveyRemove.ListCount - 1
If lstBoxSurveyRemove.List(i) = lstBoxSurveyList.Value Then
bFound = True
Exit For
End If
Next i
If Not bFound Then lstBoxSurveyRemove.AddItem lstBoxSurveyList.Value
