在Internet Explorer_Server（IWebBrowser2）上拦截WM_COMMAND（从加速器发送）
[英]Intercept WM_COMMAND (sent from an accelerator) on Internet Explorer_Server (IWebBrowser2)
问题描述
I need to intercept the Paste message that is being sent to my CHtmlView object. 
我需要拦截发送到我的CHtmlView对象的粘贴消息。 According to Spy++, it's being sent as a WM_COMMAND message - but also according to Spy++, the message isn't being sent to the CHtmlView object, but rather to the Internet Explorer_Server (or IWebBrowser2) object that it wraps. 根据Spy ++，它是作为WM_COMMAND消息发送的 - 但是根据Spy ++，消息不会发送到CHtmlView对象，而是发送到它包装的Internet Explorer_Server（或IWebBrowser2）对象。 The WM_COMMAND message in question is not seen in any other parent objects (I've found this by observation and via Spy++). 在任何其他父对象中都看不到有问题的WM_COMMAND消息（我通过观察和通过Spy ++找到了这个消息）。
How do I intercept this (or even, say, a Select All) message? 如何拦截此消息（甚至是全部选择）消息？ I've watched AfxCallWndProc for the correct WM_COMMAND message, and it doesn't show up there. 我已经看过AfxCallWndProc以获取正确的WM_COMMAND消息，并且它没有显示在那里。

To intercept a message (ex: WM_COMMAND) you need to subclass the window (in your case Internet Explorer_Server) by calling: 要拦截消息（例如：WM_COMMAND），您需要通过调用以下方式对窗口进行子类化（在您的案例中为Internet Explorer_Server）：
BOOL SetWindowSubclass(
_In_ HWND hWnd,
_In_ SUBCLASSPROC pfnSubclass,
_In_ UINT_PTR uIdSubclass,
_In_ DWORD_PTR dwRefData
);

After that your own windows procedure takes controls first and you can decide what to do with the message. 之后，您自己的Windows程序首先获取控件，然后您可以决定如何处理该消息。
