32位键盘钩子在64位应用程序意外地工作，但挂展望 [英] 32-bit Keyboard Hook unexpectedly works in 64-bit apps, but is hanging Outlook

问题描述

一直在阅读了很多关于这一个，画面只是变得泥泞。我有一个32位的应用程序，安装一个的KeyboardHook等待全局热键和唤醒。在Win 7 x64版本上运行它，我发现它挂展望x64版本的时候热键是pressed。

所以，我做了一些研究，它看起来像32位键盘钩子甚至不应该在64位应用程序的工作。时间更多的测试...

这些热键工作正常，在64位的记事本，写字板，和便签。我证实这些是64位应用程序，因为它们不具有* 32旁边在任务管理器。不挂的应用程序，它做什么，它应该。但等待...... 32位钩子DLL不能加载到64位应用程序，对吧？

一看进程资源管理器显示了钩子DLL甚至没有加载到记事本程序！ （如果我运行WOW64目录中的32位的notepad.exe，我可以看到加载到进程的DLL，所以我知道我使用的工具右）。

所以，展望挂的问题可能会或可能不会进行相关的，但为什么被钩连工作都在64位的记事本？

如果这是你的终极目标，那么它的简单和更小的对系统的影响只是使用的 RegisterHotKey 。

Have been reading a lot about this one and the picture just gets muddier. I have a 32-bit app that installs a KeyboardHook to wait for a global hotkey and wake up. Running it on Win 7 x64 edition I notice it hangs Outlook x64 edition when the hotkey is pressed.

So I did some research and it looks like 32-bit keyboard hooks aren't even supposed to work in 64 bit apps. Time for more testing...

They hotkey works fine in 64-bit notepad, wordpad, and sticky notes. I verified that these are 64-bit apps since they don't have "*32" next to them in Task Manager. Doesn't hang the app and it does what it's supposed to. But wait... a 32-bit hook dll can't be loaded into a 64-bit app, right?

A look at Process Explorer shows the hook dll isn't even loaded into the notepad process! (If I run the 32-bit notepad.exe from WOW64 directory, I can see the dll loaded into the process, so I know I'm using the tools right).

So the Outlook hanging issue might or might not be related, but why is the hook even working at all in 64-bit notepad?

解决方案

I have a 32-bit app that installs a KeyboardHook to wait for a global hotkey and wake up.

If that's your ultimate goal, then it's simpler and less of an impact on the system to just use RegisterHotKey.
