集合WithEvents不适用于动态CheckBoxes和OptionButton-VBA Excel

Question

我正在研究一个查看工作表并在用户窗体上动态创建框架，标签（带有工作表中单元格的标题），复选框和两个选项按钮的项目。 根据工作表上有多少行来重复此过程。 有多个工作表，每个工作表都有一个与之相关的用户表单。 本质上，每个工作表形式的配对都执行相同的操作。 我希望能够为每个帧选择复选框或选项按钮之一。 如果选中此复选框，则应禁用选项按钮。 选项按钮在每个框架中均能正常工作，但除此之外，创建单元之后，与单元之间没有任何连接。 我试图合并WithEvents和Collections，但无法弄清楚。 现在，我收到一个“对象没有源自动化事件”错误。 我开始对框架的所有内部工作进行硬编码，因此我知道复选框和选项按钮的逻辑适用，但是我确实希望能够动态创建它们。 非常感谢任何见解。

这是类（ClassOLF）：

Option Explicit

Public Collect As Collection

Private WithEvents cbox As MSForms.Checkbox
Private WithEvents optbtn1 As MSForms.OptionButton
Private WithEvents optbtn2 As MSForms.OptionButton

Public Property Set Checkbox(ByVal CHKbox As Checkbox)
    Set cbox = CHKbox
End Property

Private Sub cbox_Change()
            If NewChkBx.Value = True Then
                    NewOptBtn1.Enabled = False
                    NewOptBtn2.Enabled = False
                    NewOptBtn1.Value = False
                    NewOptBtn2.Value = False
                    Worksheets("SSRs").Cells(SRow, 3) = "N/A"
                    Worksheets("SSRs").Cells(SRow, 4) = ""
                    Worksheets("SSRs").Cells(SRow, 5) = ""
            End If

            If NewChkBx.Value = False Then
                    Worksheets("SSRs").Cells(SRow, 3) = ""
                    NewOptBtn1.Enabled = True
                    NewOptBtn2.Enabled = True
            End If
End Sub
Private Sub optbtn1_Click()
    Worksheets("ssrs").Cells(SRow, 4) = "Y"
    Worksheets("ssrs").Cells(SRow, 5) = ""
End Sub
Private Sub optbtn2_Click()
    Worksheets("ssrs").Cells(SRow, 4) = ""
    Worksheets("ssrs").Cells(SRow, 5) = "N"
End Sub

这是用户表单ufSSR的代码：

    Set Collect = New Collection

    ' read how many rows are in SSR
    Listarray = ThisWorkbook.Sheets("SSRs").Range("SSRs").Rows.Count

    Top = 10        'sets Top

    Worksheets("SSRs").Range("SSR_selection").Clear

    For labelCounter = 1 To Listarray

            SRow = labelCounter + 1     'sets SSRs to proper row

            ' *** places Frames ***
            Set NewFrame = ufSSRs.Controls.Add("Forms.Frame.1")

您实际上使用了错误的类。 您需要将MSForms指定为库：

Private WithEvents cbox As MSForms.Checkbox
Private WithEvents optbtn1 As MSForms.OptionButton
Private WithEvents optbtn2 As MSForms.OptionButton

因为Excel库也具有这些控件类型。
