Question

我有一个程序可以复制一系列单元格，并且需要将内容粘贴到代码中创建的新工作簿中。我可以复制数据，但每当我将工作簿更改为新创建的工作簿时，剪贴板就会丢失其数据。我考虑将单元格复制到一个数组，然后只是将数组复制到新的工作簿，但我不知道在编码时数组的大小，这几乎每次宏运行时都会有所不同。当我更改活动工作簿时，如何将数据保留在剪贴板上？

cell = "k7: l" & row
Worksheets(1).Range(cell).Select


Selection.Copy
relpath = ThisWorkbook.Path & "\" & "DispersionList.xls"

If Dir(relpath) <> "" Then
   Application.Workbooks.Open (relpath)
   Workbooks("DispersionList.xls").Activate
Else
    Call createWorkbook
End If

Worksheets(1).Cells(7, 14).Select
Selection.PasteSpecial


End Sub

如果我逐行遍历代码并检查剪贴板，它会在workbooks.open行中丢失其内容

Excel / VBA中有一些操作会使选择/剪贴板无效，例如更改任何窗口/显示设置。因此，我怀疑在更改工作表/工作簿时会调用某个事件。

您可以调试它并在逐步完成代码计算时，当选择无效时避免使用此语句（如果可能）。

或者，在事件代码中使用以下代码中的subStoreClipboard和subRestoreClipboard。要使用代码，请将其插入工作表中的新模块中 - 并在VBA中插入名为“ws_Temp”的新（隐藏）工作表。

Private mIntCutCopyMode As XlCutCopyMode
Private mRngClipboard As Range

Public Sub subStoreClipboard()
    On Error GoTo ErrorHandler
    Dim wsActiveSource As Worksheet, wsActiveTarget As Worksheet
    Dim strClipboardRange As String

    mIntCutCopyMode = Application.CutCopyMode

    If Not fctBlnIsExcelClipboard Then Exit Sub


    Application.EnableEvents = False

    'Paste data as link
    Set wsActiveTarget = ActiveSheet
    Set wsActiveSource = ThisWorkbook.ActiveSheet

    With ws_Temp
        .Visible = xlSheetVisible
        .Activate
        .Cells(3, 1).Select
        On Error Resume Next
        .Paste Link:=True
        If Err.Number Then
            Err.Clear
            GoTo Finalize
        End If
        On Error GoTo ErrorHandler
    End With

    'Extract link from pasted formula and clear range
    With Selection
        strClipboardRange = Mid(.Cells(1, 1).Formula, 2)
        If .Rows.Count > 1 Or .Columns.Count > 1 Then
            strClipboardRange = strClipboardRange & ":" & _
                Mid(.Cells(.Rows.Count, .Columns.Count).Formula, 2)
        End If
        Set mRngClipboard = Range(strClipboardRange)
        .Clear
     End With

Finalize:
    wsActiveSource.Activate
    wsActiveTarget.Parent.Activate
    wsActiveTarget.Activate

    ws_Temp.Visible = xlSheetVeryHidden
    Application.EnableEvents = True

    Exit Sub
ErrorHandler:
    Err.Clear
    Resume Finalize
End Sub


Public Sub subRestoreClipboard()
    Select Case mIntCutCopyMode
        Case 0:
        Case xlCopy: mRngClipboard.Copy
        Case xlCut:  mRngClipboard.Cut
    End Select

End Sub

Private Function fctBlnIsExcelClipboard() As Boolean
    Dim var As Variant
    fctBlnIsExcelClipboard = False
    'check if clipboard is in use
    If mIntCutCopyMode = 0 Then Exit Function
    'check if Excel data is in clipboard
    For Each var In Application.ClipboardFormats
        If var = xlClipboardFormatCSV Then
            fctBlnIsExcelClipboard = True
            Exit For
        End If
    Next var
End Function

如何在vba中更改工作簿后保留剪贴板数据？
