excel - 覆盖范围内的值，该范围是列表框的源范围

Question

我在用户窗体上有一个列表框，它有一个源范围，我试图通过提供来自用户窗体的值来覆盖它，但是一旦我覆盖特定单元格，事件 ListBox1_Click()启动这是不可取的，因为它会重新填充用户窗体上的数据。

Private Sub ListBox1_Click()

Application.EnableEvents = False
Dim i As Long, fRow As Long

For i = 0 To ListBox1.ListCount - 1
    If ListBox1.Selected(i) Then
        If i > 0 Then
            HSht.Range("cRow").Value = i + 1
            fRow = HSht.Range("cRow").Value
            Call getData(fRow)
            HSht.Range("LRow").Value = getlastRow()
            Me.ItemLbl.Caption = "Item number :" & HSht.Range("cRow").Value - 1 & " of " & HSht.Range("LRow").Value - 1
        End If
        Exit For
    End If
Next i

Application.EnableEvents = True
End Sub

这是更新按钮代码:

Private Sub cmdUpdate_Click()

Application.EnableEvents = False

'Update
Dim fRow As Long, i As Long
fRow = HSht.Range("cRow").Value
Call updateData(fRow)
HSht.Range("LRow").Value = getlastRow()
Me.ItemLbl.Caption = "Item number :" & HSht.Range("cRow").Value - 1 & " of " & HSht.Range("LRow").Value - 1

'MsgBox "Data updated successfully"
Application.EnableEvents = True
End Sub

例如，让您有 10 个字段，并且您在用户窗体上有 10 个文本框来查看/修改数据，但是您还有多列列表框来查看和滚动表格格式的数据，当我向上或向下滚动时，我会在其中获取特定的行数据用户窗体上的文本框，我还有一个按钮，上面写着“覆盖”，以防我想通过用户窗体修改工作表上的数据。但是一旦它修改了工作表中的一个单元格，就会触发“Listbox1_click”事件并覆盖用户窗体上的数据。

Application.EnableEvents = false won't affect UserForms .如果事件被禁用，您必须创建一个属性并在事件开始和退出事件子时检查它的值，例如:

' Top of UserForm-Class
Public EnableEvents As Boolean ' if Private code outside the userform can't change value.
'One should add a Letter/Getter to have more control over the property (exposing the variable that stores a property-value isn't recommended I think, with Get/Let we can perform checks or just make the Letter private, but the Getter public)
Private Sub UserForm_Initialize()
    Me.EnableEvents = True
End Sub

Private Sub ListBox1_Click()
If Me.EnableEvents = False Then 'the first three lines of code suppress the events-code execution if EnableEvents = False and must be on top of every event that you want to have disabled.
  Exit Sub
End If
 'Me.EnableEvents = False should be set on top of button code and Me.EnableEvents = True at buttom if other events of from should be suppressed.

Dim i As Long, fRow As Long

For i = 0 To ListBox1.ListCount - 1
  ...

End Sub

Private Sub cmdUpdate_Click()
If Me.EnableEvents = False Then 'the first three lines of code suppress the events-code execution and must be on top of every event that you want to have disabled.
  Exit Sub
End If
Me.EnableEvents = False 'disable Form-Events

... 'Button-Code

Me.EnableEvents = True 'reenable events
End Sub
