正　文:

在这个剪切板功能里面，32bit和64bit主要的差异：

1.64 bit的Declare 后必须有PtrSafe 

2.64 bit的指针\句柄必须使用LongPtr类型

32 bit：

    Private Declare Function OpenClipboard Lib "user32.dll" ( _
            ByVal hWnd As Long) As Long
    Private Declare Function GetClipboardData Lib "user32.dll" ( _
            ByVal wFormat As Long) As Long
    Private Declare Function CloseClipboard Lib "user32.dll" () As Long

64 bit：

    Private Declare PtrSafe Function OpenClipboard Lib "user32.dll" ( _
            ByVal hWnd As LongPtr) As Long
    Private Declare PtrSafe Function GetClipboardData Lib "user32.dll" ( _
            ByVal wFormat As LongPtr) As Long
    Private Declare PtrSafe Function CloseClipboard Lib "user32.dll" () As Long
