Question

I previously asked a question and received a response from T.M. that answered it perfectly!

但是，当我以辅助形式输入代码时，会收到与主形式中最初收到的错误相同的错误。

下面是放置在表单和类模块中的代码以及一些屏幕截图，它们可以更好地说明第二种表单，因为我不确定我是否解释得很清楚...

非常感谢大家！

采用以下格式的代码：

Dim cBar As clsBar

Private Sub UserForm_Initialize()

    On Error GoTo Whoa
    Application.EnableEvents = False

    Set cBar = New clsBar
    cBar.Initialize Me

Letscontinue:
    Application.EnableEvents = True
    Exit Sub
Whoa:
    MsgBox Err.Description
    Resume Letscontinue

End Sub

2nd form that the code is not working in

在第二个表单中单击“复制”或“粘贴”时，出现错误：

运行时错误'438'：
    对象不支持此属性或方法。

对第二个UserForm调用的必要修改

似乎出现了直接在第一个表单中显示第二个表单的问题，因为单击事件也从被单击的“ CAT”控件中获取了返回值。

这对我有用：

建议仅在您的UF模块中通过ShowYODA显示第二个用户表单，即调用位于单独模块中的过程，例如

在单独的模块中调用第二种表单的示例

Sub ShowYODA
    With New YODA           ' temporary new UF instance
        .Show vbModeless
    End With
End Sub

需要在以下事件过程和调用的帮助函数中进行更改（仅对文本框使用结束空间标记，这些文本框将在调用事件中进行修剪）：

相关点击事件

'Click event of the copy button
Private Sub cmdCopyButton_Click(ByVal Ctrl As Office.CommandBarButton, CancelDefault As Boolean)
Dim sACN As String
sACN = ActiveControlName(fmUserform)    ' find control's name
If Right$(sACN, 1) = " " Then           ' marker (=ending space) for textboxes only!
       Debug.Print Trim(sACN) & ".Copy"
   fmUserform.Controls(Trim(sACN)).Copy ' << instead of fmUserform.ActiveControl.Copy /438 unterstü.d.Meth nicht!
   CancelDefault = True
End If
End Sub

'Click event of the paste button
Private Sub cmdPasteButton_Click(ByVal Ctrl As Office.CommandBarButton, CancelDefault As Boolean)
Dim sACN As String
sACN = ActiveControlName(fmUserform)    ' find control's name
If Right$(sACN, 1) = " " Then           ' marker (=ending space) for textboxes only!
       Debug.Print Trim(sACN) & ".Copy"
   fmUserform.Controls(Trim(sACN)).Paste    ' << instead of fmUserform.ActiveControl.Copy
   CancelDefault = True
End If
End Sub

修改后的辅助功能ActiveControlName()

Function ActiveControlName(form As MSForms.UserForm) As String
'cf Site: https://stackoverflow.com/questions/47745663/get-activecontrol-inside-multipage
'Purpose: get ActiveControl name string and mark text boxes by an ending space
 Dim MyMultiPage As MSForms.MultiPage, myPage As MSForms.Page
 If form.ActiveControl Is Nothing Then
    ' do nothing
 ElseIf TypeName(form.ActiveControl) = "MultiPage" Then
    Set MyMultiPage = form.ActiveControl
    Set myPage = MyMultiPage.SelectedItem
    ActiveControlName = myPage.ActiveControl.Name
    If TypeName(form.Controls(ActiveControlName)) = "TextBox" Then ActiveControlName = ActiveControlName & " "
 Else
    ActiveControlName = form.ActiveControl.Name
    If TypeName(form.Controls(ActiveControlName)) = "TextBox" Then ActiveControlName = ActiveControlName & " "
 End If
 End Function
