excel - 表单中的表单 - VBA 右键单击​​复制/粘贴多页

问题描述

我之前问过一个问题，并收到了 TM 的回复，完美地回答了它！

但是，当我在辅助表单中输入代码时，我收到了与最初在主表单中收到的相同的错误。

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

非常感谢大家！

代码形式：

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

类模块中的代码

'Popup objects
Private cmdBar As CommandBar
Private WithEvents cmdCopyButton As CommandBarButton
Private WithEvents cmdPasteButton As CommandBarButton

'Useform to use
Private fmUserform As Object

'Control array of textbox
Private colControls As Collection

'Textbox Control
Private WithEvents tbControl As MSForms.TextBox

'Adds all the textbox in the userform to use the popup bar
Sub Initialize(ByVal UF As Object)
    Dim Ctl As MSForms.Control
    Dim cBar As clsBar

    For Each Ctl In UF.Controls
        If TypeName(Ctl) = "TextBox" Then

            'Check if we have initialized the control array
            If colControls Is Nothing Then
                Set colControls = New Collection
                Set fmUserform = UF
                'Create the popup

            'Create a new instance of this class for each textbox

            cBar.AssignControl Ctl, cmdBar
            'Add it to the control array
            colControls.Add cBar

        End If
    Next Ctl
End Sub

    If Button = 2 And Shift = 0 Then

Private Sub CreateBar()

End Sub

表格 1

代码不起作用的第二种形式

当我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。

在线上：fmUserform.Controls(sACN).Paste

解决方案

第二次用户窗体调用的必要修改

问题似乎直接在第一个表单中显示第二个表单，并且因为单击事件也从单击的“CAT”控件获取返回值。

这对我有用：

  1. 建议仅在您的 UF 模块中显示第二个用户窗体ShowYODA，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形式的示例

Sub ShowYODA
    With New YODA           ' temporary new UF instance
        .Show vbModeless
    End With
End Sub
  1. 以下事件过程和调用的辅助函数需要更改（仅对将在调用事件中修剪的文本框使用结束空格标记）：

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

修改辅助函数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
