Question

我正在研究一个项目，该项目查看工作表并在用户表单上动态创建一个框架，一个标签（带有工作表上单元格的标题），一个复选框和两个选项按钮。基于工作表上的许多行来迭代此过程。有多个工作表，每个工作表都有一个与之关联的用户表单。实质上，每个纸张形式的配对都做同样的事情。我希望能够为每个框选择复选框或其中一个选项按钮。如果选中该复选框，则应禁用选项按钮。选项按钮在每个框架内正常工作，但除此之外，在创建单元格后没有任何连接。我试图将WithEvents和Collections合并，但一直未能弄清楚。现在我得到一个＆＃34;对象不会提供自动化事件＆＃34;错误。我开始硬编码框架的所有内部工作，所以我知道我的复选框和选项按钮的逻辑工作，但我真的希望能够动态创建这些。非常感谢任何见解。

这是班级（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

Answer 1

你实际上是在使用错误的类。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库也有这些控件类型。

CollectionEvent不适用于动态CheckBoxes和OptionButtons - VBA excel
