vba - 使用SetWindowsHookEx。在 Excel 2010 中

Question

这个功能让我抓狂!我试图使用 SetWindwosHookEx 来避免用户的一些击键，但我无法使其正常工作。

我一直在网上查找许多代码，但我不明白为什么它对我不起作用。首先，这是因为我使用的是 Excel 2010(64 位)，而我的代码不适合它，但现在我不知道。

基本上，我创建了一个简单的代码，当我拉动“g”时，它会显示一条消息，但实际情况是，当拉动任意键时，Excel 会崩溃。当我逐步运行代码时它不会崩溃，但如果我拉“g”，消息会出现三次!

这是我的代码:

#If Win64 Then

Public Declare PtrSafe Function SetWindowsHookEx Lib "user32" Alias "SetWindowsHookExA" (ByVal idHook As LongPtr, ByVal lpFn As LongPtr, ByVal hmod As LongPtr, ByVal dwThreadId As LongPtr) As LongPrt

64 位的正确声明是:

Public Declare PtrSafe Function UnhookWindowsHookEx Lib "user32" (ByVal hHook As LongPtr) As Long
Public Declare PtrSafe Function SetWindowsHookEx Lib "user32" Alias "SetWindowsHookExA" (ByVal idHook As Long, ByVal lpFn As LongPtr, ByVal hmod As LongPtr, ByVal dwThreadId As Long) As LongPtr
Public Declare PtrSafe Function CallNextHookEx Lib "user32" (ByVal hHook As LongPtr, ByVal nCode As Long, ByVal wParam As LongPtr, lParam As Any) As LongPtr
Public Declare PtrSafe Function GetModuleHandle Lib "kernel32" Alias "GetModuleHandleA" (ByVal lpModuleName As String) As LongPtr
Public Declare PtrSafe Function GetCurrentThreadId Lib "kernel32" () As Long
Public Declare PtrSafe Function GetKeyState Lib "user32" (ByVal nVirtKey As Long) As Integer
Private Declare PtrSafe Function SendDlgItemMessage Lib "user32" Alias "SendDlgItemMessageA" (ByVal hDlg As LongPtr, ByVal nIDDlgItem As Long, ByVal wMsg As Long, ByVal wParam As LongPtr, ByVal lParam As LongPtr) As LongPtr
Private Declare PtrSafe Function GetClassName Lib "user32" Alias "GetClassNameA" (ByVal hwnd As LongPtr, ByVal lpClassName As String, ByVal nMaxCount As Long) As Long

我实际上无法看到您发布的代码在 64 位上如何运行。
