如何将32位VBA代码转换为64位VBA代码

Question

我试图运行宏代码,但由于我使用的是64位Excel 2016,因此这段代码无效.请帮我解决这个问题.

Private Declare Function FindWindowEx Lib "User32" Alias "FindWindowExA" _
(ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, _
ByVal lpsz2 As String) As Long

Private Declare Function IIDFromString Lib "ole32" _
(ByVal lpsz As Long, ByRef lpiid As GUID) As Long

Private Declare Function AccessibleObjectFromWindow Lib "oleacc" _
(ByVal hWnd As Long, ByVal dwId As Long, ByRef riid As GUID, _
ByRef ppvObject As Object) As Long

Answer 1

这些应该适用于64位Excel

Private Declare PtrSafe Function FindWindowEx Lib "user32" Alias "FindWindowExA" _
  (ByVal hWnd1 As LongPtr, ByVal hWnd2 As LongPtr, ByVal lpsz1 As String, _
  ByVal lpsz2 As String) As LongPtr

Private Declare PtrSafe Function IIDFromString Lib "ole32" _
  (ByVal lpsz As LongPtr, ByRef lpiid As GUID) As LongPtr

Private Declare PtrSafe Function AccessibleObjectFromWindow Lib "oleacc" _
  (ByVal Hwnd As LongPtr, ByVal dwId As LongPtr, ByRef riid As GUID, _
  ByRef ppvObject As Object) As LongPtr

如果您需要在两者上运行它,您可以使用以下内容 #If VBA7

#If VBA7 Then
    '64 bit declares here
#Else
    '32 bit declares here
#End If

可以在此处找到PtrSafe Win32 API声明的一个很好的资源:Win32API_PtrSafe.txt

我不太确定IIDFromString,AccessibleObjectFromWindow但我认为它们应该subs代替functions.并且lpsz应该String如下.也许有人可以证实这一点？

Private Declare PtrSafe Sub IIDFromString Lib "ole32" ( _
  ByVal lpsz As String, ByRef lpiid As GUID)

Private Declare PtrSafe Sub AccessibleObjectFromWindow Lib "oleacc" _
  (ByVal Hwnd As LongPtr, ByVal dwId As LongPtr, ByRef riid As GUID, _
  ByRef ppvObject As Object)
