Hey all,
I'm looking for a way to view all of the windows messages, like Spy ++
does. It's fairly trivial to do it for the current application, but how can
I take that knowledge to the bigger (system-wide) picture?
Thanks,

Hi,
Thanks for posting in the community.
First of all, I would like to confirm my understanding of your issue.
From your description, I understand that you wants to know how to monitor
all the windows messages in System Wide From VB.NET something like Spy++?
Have I fully understood you? If there is anything I misunderstood, please
feel free to let me know.
I think you may need to use the Hook technique to set an system-level
Global Hook to WH_GETMESSAGE.
But Global Hook is Not Supported in .NET Framework
You cannot implement global hooks in Microsoft .NET Framework. To install a
global hook, a hook must have a native DLL export to insert itself in
another process that requires a valid, consistent function to call into.
This requires a DLL export, which .NET Framework does not support. Managed
code has no concept of a consistent value for a function pointer, because
these function pointers are proxies that are built dynamically.

You will have to set up a global message hook ('WH_GETMESSAGE '). Maybe
you can base your sample on this example program written by Paul Kimmel:

Herfried,
this is a really good article, however I have a question for you. Now, the
way I understand Global Hooks is that its not possible in .NET because it
cannot be exported like a regular DLL into other processes. (I knew this
before Peter made his statement).
I have recently been trying to do global hooks in .NET with mouse events,
now, looking at this article, I wonder, is the same possible or am I
misreading this article as a global hook solution?
Thanks,
CJ

Actually, if you have some global hook c++ code for the mouse that would be
awesome... I'm sure I could find some online but hell, why bother.

Low level hooks are possible in .NET - but you should be aware that
WH_KEYBOARD_LL and WH_MOUSE_LL only work on NT based systems. If you
want this to work on any Windows OS, you'll need to use WH_KEYBOARD.
And, you can't set a global hook using WH_KEYBOARD from VB.NET...
It is fairly trivial to implement the hook as a C/C++ dll and then call
it from your VB.NET app. If you need an example, let me know. I have
some code I wrote to do this that I could post.

I haven't forgotten you or not noticed this message... Unfortunately,

a HD crash a few months ago... Never fear, I worked on putting a little
sample together today. I expect that I will be able to post the results

in the first post.
I am in the process of deciding the IPC mechanisms to use for
communication between

could be C++ or C#. The API as such might be talking to the
underlying application (UA) via WM_COPYDATA messages.

have a c++ program which calls and c++ dll (i created both). The dll
uses SendMessage to pass messages back to the calling .exe, and the

WindProc().
What i want is to receive these messages ( the contents of each message
will be plain text), in python using a callback (i think this is what i
need).
