Excel 2013 64位VBA：剪贴板API不工作

我曾经可以在Excel VBA中使用Windows API调用来设置剪贴板上的文本。但自从升级到64位Office 2013后，我就不能了。下面是一些没有错误的代码，但它也没有在剪贴板上设置任何文本。有人能帮我测试和排除故障吗？
将下面的代码粘贴到VBA中的代码模块后，您可以通过键入Clipboard_SetData("Copy this to the clipboard.")在即时窗口中测试它，它应该将该文本设置在剪贴板上，您可以将其粘贴到任何其他应用程序中。
（我使用的是Windows 8，所以我不能使用Microsoft Forms或数据对象来操作剪贴板。它在Windows 8上不能正常工作。）

**更新和编辑：**下面的代码已被更正，现在可以在64位Excel中正常工作，感谢Jason Kurtz的回答。如果你觉得这有用，请投票支持他的回答。

好，我知道了......
您需要在您的代码版本中更改此行：

Private Declare PtrSafe Function lstrcpy Lib "kernel32" (ByVal lpString1 As String, ByVal lpString2 As String) As LongPtr

对此：

Private Declare PtrSafe Function lstrcpy Lib "kernel32" (ByVal lpString1 As Any, ByVal lpString2 As Any) As LongPtr

如果您按原样单步执行代码，您将看到在调用lstrcopy时lpGlobalMemory的值发生了变化。当类型更改为Any时，该值保持不变。
在Windows 7上对我有效。希望对你有效!

我知道这个问题现在已经解决了，但是我更喜欢这种****简单得多的方法，它可以独立于体系结构工作，而且我喜欢用一个函数来读写剪贴板的方法。

Function Clipboard(Optional StoreText As String) As String
'PURPOSE: Read/Write to Clipboard
'Source: ExcelHero.com (Daniel Ferry)

Dim x As Variant
'Store as variant for 64-bit VBA support
  x = StoreText
'Create HTMLFile Object
  With CreateObject("htmlfile")
    With .parentWindow.clipboardData
      Select Case True
        Case Len(StoreText)
          'Write to the clipboard
            .setData "text", x
        Case Else
          'Read from the clipboard (no variable passed through)
            Clipboard = .GetData("text")
      End Select
    End With
  End With
End Function

完全按照如下所示使用代码：
http://msdn.microsoft.com/en-us/library/office/ff192913.aspx
除了在所有API声明的Declare之后插入PtrSafe。
代码本身应该位于模块中。
就像这样：

Option Explicit

Declare PtrSafe Function GlobalUnlock Lib "kernel32" (ByVal hMem As Long) _
   As Long
Declare PtrSafe Function GlobalLock Lib "kernel32" (ByVal hMem As Long) _

   ByVal dwBytes As Long) As Long
Declare PtrSafe Function CloseClipboard Lib "User32" () As Long
Declare PtrSafe Function OpenClipboard Lib "User32" (ByVal hwnd As Long) _
   As Long
Declare PtrSafe Function EmptyClipboard Lib "User32" () As Long
Declare PtrSafe Function lstrcpy Lib "kernel32" (ByVal lpString1 As Any, _
   ByVal lpString2 As Any) As Long
Declare PtrSafe Function SetClipboardData Lib "User32" (ByVal wFormat _
   As Long, ByVal hMem As Long) As Long

Public Const GHND = &H42
Public Const CF_TEXT = 1
Public Const MAXSIZE = 4096

Function ClipBoard_SetData(MyString As String)
   Dim hGlobalMemory As Long, lpGlobalMemory As Long
   Dim hClipMemory As Long, X As Long

   ' Allocate moveable global memory.
   '-------------------------------------------
   hGlobalMemory = GlobalAlloc(GHND, Len(MyString) + 1)

   ' Lock the block to get a far pointer
   ' to this memory.
   lpGlobalMemory = GlobalLock(hGlobalMemory)

   ' Copy the string to this global memory.
   lpGlobalMemory = lstrcpy(lpGlobalMemory, MyString)

   ' Unlock the memory.
   If GlobalUnlock(hGlobalMemory) <> 0 Then
      MsgBox "Could not unlock memory location. Copy aborted."
      GoTo OutOfHere2
   End If

   ' Open the Clipboard to copy data to.
   If OpenClipboard(0&) = 0 Then
      MsgBox "Could not open the Clipboard. Copy aborted."
      Exit Function
   End If

   ' Clear the Clipboard.
   X = EmptyClipboard()

   ' Copy the data to the Clipboard.
   hClipMemory = SetClipboardData(CF_TEXT, hGlobalMemory)

OutOfHere2:

   If CloseClipboard() = 0 Then
