Vba 使用SetWindowsHookEx。在Excel 2010中

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

我一直在网上寻找很多代码，但我不明白为什么它不适合我。首先，这是因为我使用的是Excel 2010（64位），而我的代码不适用于它，但现在我不知道

基本上，我已经创建了一个简单的代码，当我拉“g”时，它会显示一条消息，但当拉任意键时，Excel会崩溃。当我一步一步地运行代码时，它不会崩溃，但是如果我拉“g”，消息会出现三次

这是我的代码：

实际上，我看不出您发布的代码在64位上是如何运行的。

您需要查看您的声明-并非所有内容都应该是

LongPtr

。那些应该是

LongPtr

而不是

LongPrt

。很抱歉我的无知，但哪些不是LongPtr？这是我第一次为64位编码。谢谢，谢谢！。事实上，它并没有真正起作用。一旦我按下一个键，代码就会进入一个不可阻挡的循环。在准备好关于hook、setwindowsex、callnexthookex等的信息和许多代码后，我看不到错误。所有示例代码看起来都很简单，但我无法让它再次工作。嗨，我做了一些改进，这段代码几乎可以正常工作，但有两个问题：当我运行代码时，该函数不返回我正在提取的密钥，因此不会写入任何内容，“NewProc_64”函数会运行两次：
