Looking for a 32/64 bit WM_MOVING global hook source C++ sample.

Hello,

I'm looking for a source sample to detect any window move (thus, a global hook) in x86/x64 windows systems.
I've searched a bit but all I found about global hooks end in keyboard/mouse samples.

I've checked the MinHook project which comes with different type of keyboard samples but when I tried to adapt it to detect any WM_MOVING (MoveWindow) event, ~~I wasn't able to make it work.~~

UPDATE: I finally managed to hook the window move event (hooking the Windows'API DefWindowProcW
with event number WM_MOVING = 0x0216).
The problem is that MinHook only works locally on the own app's events and not globally as I was intending.

The reason I was looking for a sample is because I am not a C++ expert and was looking for some sort of sample to ahve a look.

Thank you in advance.

Why are you not implementing a hooking function of your own using the API ?
What do you mean with "was not able to make it work?"

This article has some useful information on creating a DLL that loads into each applications's address space. The article is a bit dated in that the advice on creating a shared section of memory doesn't work with Windows Vista and later.

Hooks and DLLs[^]

The key is - I think - the WH_GETMESSAGE hook mechanism. It will give all windows messages returned by GetMessage.
