Question

我发送电子表格以更新信息，然后发回给我。

我进行验证并锁定单元格以强制用户输入准确的信息。我使用VBA禁用剪切复制和粘贴功能的解决方法。另外，我插入了一个VBA函数来强制用户在宏中打开Excel文件。

我正在尝试跟踪这些更改，因此我知道当我收回表单时更新了什么。当有人保存文档时我会收到错误，并且随机地将文档完全锁定在文档之外。

如何通过VBA突出显示更改，而不是通过Excel的共享/跟踪更改选项？

的ThisWorkbook：

Option Explicit

Const WelcomePage = "Macros"

Private Sub Workbook_BeforeClose(Cancel As Boolean)
    Call ToggleCutCopyAndPaste(True)

     'Turn off events to prevent unwanted loops
    Application.EnableEvents = False

     'Evaluate if workbook is saved and emulate default propmts
    With ThisWorkbook
        If Not .Saved Then
            Select Case MsgBox("Do you want to save the changes you made to '" & .Name & "'?", _
                vbYesNoCancel + vbExclamation)
            Case Is = vbYes

                Cancel = True
            End Select

    If SaveAs = True Then
        newFname = Application.GetSaveAsFilename( _
        fileFilter:="Excel Files (*.xls), *.xls")
        If Not newFname = "False" Then ThisWorkbook.SaveAs newFname
    Else
        ThisWorkbook.Save

End Sub

Private Sub Workbook_Activate()
    Call ToggleCutCopyAndPaste(False)
End Sub

Private Sub Workbook_Deactivate()
    Call ToggleCutCopyAndPaste(True)

我修改了你的模块，如下所示，并调用了'This Workbook'的'Workbook_Open'和'Workbook_Beforeclose'部分中的函数。在前者中，函数参数为False，而在后者中，参数为True。它运作良好。你也可以参考Yogesh的代码，它更全面。其URL是： http://ygblogs.blogspot.com/2009/04/macros-in-excel-disable-cut-copy-paste.html

将以下内容插入模块：

Option Explicit
Dim Allow As Boolean, ctlId As Integer, Enabled As Boolean

Function ToggleCutCopyAndPaste(Allow As Boolean)

    'Activate/deactivate cut, copy, paste and pastespecial shortcut keys
    With Application
        Select Case Allow
            Case False
                .OnKey "^c", "CutCopyPasteDisabled"
                .OnKey "^v", "CutCopyPasteDisabled"
                .OnKey "^x", "CutCopyPasteDisabled"
                .OnKey "+{DEL}", "CutCopyPasteDisabled"
                .OnKey "^{INSERT}", "CutCopyPasteDisabled"           
            Case True
                .OnKey "^c"
                .OnKey "^v"
                .OnKey "^x"
                .OnKey "+{DEL}"
                .OnKey "^{INSERT}"
        End Select
        .CutCopyMode = Allow
        .CellDragAndDrop = Allow
    End With

    'Activate/Deactivate specific menu item
    Dim cBar As CommandBar
    Dim cBarCtrl As CommandBarControl, i As Integer

    For i = 1 To 4
        If i = 1 Then ctlId = 21
        If i = 2 Then ctlId = 19
        If i = 3 Then ctlId = 22
        If i = 4 Then ctlId = 755        

        For Each cBar In Application.CommandBars
            If cBar.Name <> "Clipboard" Then
                Set cBarCtrl = cBar.FindControl(ID:=ctlId, recursive:=True)
                If Not cBarCtrl Is Nothing Then cBarCtrl.Enabled = Allow
            End If
        Next
    Next i    
End Function

在VBA编辑器的ThisWorkbook部分插入以下内容：

Private Sub Workbook_BeforeClose(Cancel As Boolean)    
    ToggleCutCopyAndPaste (True)   
End Sub

Private Sub Workbook_Open()    
    ToggleCutCopyAndPaste (False)    
End Sub

当您需要跟踪和比较更改时，有一种简单的方法可以不使用宏：尝试Version Control add-in for Excel。

您可以将原始电子表格与从其他用户收到的版本进行比较。理想情况下，他们也应该安装加载项，但不一定。

如果您想跟踪宏模块中的更改，那么此Version Control for VBA macros就是救星。
