vba - 我可以获取 Excel 剪贴板数据的源范围吗？

Question

如果剪贴板包含 Excel 工作表范围，您可以使用 DataObject 对象访问该范围的数据

您还可以找到该数据的实际源范围（即工作表、行和列）吗？

或者，您能找到最后复制的范围，它用虚线轮廓边框（不是所选范围）表示吗？

最好使用 Excel 2003 VBA

Answer 1

此代码在 Excel 2019 64 位中用于获取剪贴板上的单元格范围，而不是单元格的内容。

fGetClipRange 返回 Excel 范围的范围对象，该范围对象被剪切或复制到剪贴板上，包括书籍和工作表。它使用“链接”格式直接从剪贴板中读取它，并且需要此格式的 ID 号。与注册格式关联的 ID 可以更改，因此 fGetFormatId 从格式名称中查找当前格式 ID。使用 Application.CutCopyMode 确定单元格是否被剪切或复制。

Answer 2

不直接，不 - 剪贴板对象似乎只包含单元格的值（尽管 Excel 显然以某种方式记住了边框）：

Sub testClipborard()

    Dim test As String
    Dim clipboard As MSForms.DataObject
    Set clipboard = New MSForms.DataObject

    clipboard.GetFromClipboard
    test = clipboard.GetText

    MsgBox (test)

End Sub

请注意，您需要参考 Microsoft Forms 2.0 库才能运行它（如果单元格中没有值，它也会失败）。

话虽如此，您可以尝试以下操作 - 将其添加到 VBA 编辑器中的模块中。

Public NewRange As String 
Public OldRange As String 
Public SaveRange As String 
Public ChangeRange As Boolean 

并在工作表对象中使用以下内容

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range) 

     'save previous selection
    OldRange = NewRange 

     'get current selection
    NewRange = Selection.Address 

     'check if copy mode has been turned off
    If Application.CutCopyMode = False Then 
        ChangeRange = False 
    End If 

     'if copy mode has been turned on, save Old Range
    If Application.CutCopyMode = 1 And ChangeRange = False Then 
         'boolean to hold "SaveRange" address til next copy/paste operation
        ChangeRange = True 
         'Save last clipboard contents range address
        SaveRange = OldRange 
    End If 

End Sub 

它似乎有效，但是，它也可能相当容易出现不同的错误，因为它试图解决剪贴板的问题。 http://www.ozgrid.com/forum/showthread.php?t=66773
