c# - Receive messages of other window

Question

What I'm trying to do: receive messages of other process window (Spy++).

For example: I opened new notepad window: http://i.stack.imgur.com/vNg6h.png

And then I moved the mouse over the notepad window, the windows will send this message to the notepad window (or to the main window child window/s):

WM_MOUSEMOVE xPos=100,yPos=200

I want to receive this message exactly when then mouse event is happening (by event or while loop) (probably while loop with Application.doEvents() and Threading.Thread.Sleep(1)).

What I have tried:

• create messages listener by the ManagedSpyLib (if you will import this library you can't compile your project... and if you will succeed to import this library it's not built for this mission)
• I also searched about it and this is the most relevant result: http://www.codeproject.com/Articles/3923/InterSpy-An-integrated-Windows-message-trace-and-f but this is a c++ project and I'm trying to do it in C# or VB.NET.

Good example is better than explanation for me. :)

Answer 1

您需要查看HOOK。这就是 SPY++ 的工作原理。但是，.Net 不太适合这个，因为你必须使用很多 WIN32 API 函数。

Answer 2

您需要的钩子是WH_CALLWNDPROC和WH_GETMESSAGE。而这些需要 DLL 注入。您不能注入托管代码，因此您需要使用非托管代码进行挂钩。然后，您可以让您的非托管注入 DLL 与您的 C# 应用程序进行通信，但您将不得不承认尝试用 C# 编写挂钩代码的失败。
