我曾经能够在 Excel VBA 中使用 Windows API 调用在剪贴板上设置文本。但是自从升级到 64 位 Office 2013 后,我就不能了。下面是一些不会出错的代码,但它也没有在剪贴板上设置任何文本。有人可以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,您可以通过键入在即时窗口中对其进行测试,Clipboard_SetData("Copy this to the clipboard.")它应该在剪贴板上设置该文本,并且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 上无法正常工作。)

更新和编辑:下面的代码已经更正,现在可以在 64 位 Excel 中正常工作,这要感谢 Jason Kurtz 在下面的回答。如果您觉得这很有用,请投票支持他的答案。

好的,我现在明白了……

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 lpGlobalMemory 的值在调用 lstrcopy 时发生了变化。当类型更改为 Any 时,值保持不变。

在 Windows 7 上为我工作。希望它对你有用!

完全按照此处所示使用代码:

http://msdn.microsoft.com/en-us/library/office/ff192913.aspx

除了在 Declare 之后为所有 API 声明插入 PtrSafe。

代码本身应该在一个模块中。

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) _
   As Long
Declare PtrSafe Function GlobalAlloc Lib "kernel32" (ByVal wFlags 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:
