形状复制粘贴计时问题 - Excel VBA

sif*_*far 5 excel clipboard winapi vba shapes

我使用的是 Windows 10 Enterprise 64 位、Office 2016 Pro 64 位。我正在尝试将 2 个形状从一个工作表复制到另一个工作表。

以下 API 代码有时可以工作，但大多数时候它会针对复制或粘贴发出错误 1004（剪贴板计时问题）。我尝试过使用不同的解决方案，例如计时器、等待、API 等，但大多数时候看起来很慢并且有错误！我还尝试将图像粘贴到每个合并单元格的两端。我还附上了一份样本文件以供检查。

我不记得了，但我在某处读到，如果我创建单独的复制和粘贴函数/过程，那么它可能会解决问题，尽管不确定！

编辑：

@iinspectable，这不是正常的复制粘贴问题，而是如果复制粘贴涉及循环（即多次复制粘贴），则会出现剪贴板计时问题。这是一个示例，其中SingleCopyPaste过程有效，但MultipleCopyPaste过程无效。我希望你现在明白我的意思了。

选项显式

Sub MultipleCopyPaste()
    Dim shp As Shape

   For Each shp In Sheet1.Shapes
      shp.CopyPicture
      Sheet2.Paste Sheet2.Range(shp.TopLeftCell.Address)
    Next shp
End Sub


Sub SingleCopyPaste()
    Dim shp As Shape

    Set shp = Sheet1.Shapes("Arrow")
    shp.CopyPicture
   Sheet2.Paste Sheet2.Range(shp.TopLeftCell.Address)

End Sub

以下是如果粘贴失败则重试的示例：

Sub Tester()

    Dim pic, i As Long

    Set pic = Sheet1.Shapes("testPic")

    For i = 1 To 100
        pic.Copy
        PastePicRetry Sheet2.Cells(i, 2)
    Next i

End Sub

'paste problem fix
Sub PastePicRetry(rng As Range)
    Dim i As Long
    Do While i < 20
        On Error Resume Next
        rng.PasteSpecial
        If Err.Number <> 0 Then
            Debug.Print "Paste failed", i
            DoEvents
            i = i + 1
        Else
            Exit Do
        End If
        On Error GoTo 0
        i = i + 1
    Loop
End Sub
