next is to realize CBTHook and forget the DialogMonitorOPS…
And after that rewrite 3dsmax
Nice, it even works outside max’s window Sometimes it stops working but the idea is great!
I’m suddenly flooded in work so somewhere next week I’ll hope to find the time to play around a bit more…
Added max restriction (optional) and mousewheel event.
For some reason though max hangs for a few seconds every time I close a window… does anyone know why?

i realize now i could implement the max restriction by supplying the callback with the 3dsmax thread id instead of the null pointer.
–EDIT: That seems incorrect.
i will also try to load the callback on a seperate thread to try to avoid the hang on title bar buttons.
The cool thing about Hooks is that the hook procedure can return nonzero value to prevent the system from passing the message to the target window procedure. If you are using the Events system it’s easy to add Handled property to Event Argument to control passing the message. For example, when user Right-Clicks in viewport it causes popping-up the Quad Menu. In some situation when you want to change this behavior you can cancel passing the message to the target window (viewport) using MouseDown event.
Apparently the issue with the title bar is a known bug cause by windows themes.
Doing some test with the mouse hook code posted above, did anyone ever solve the delay while closing windows?
I spent a few hours trying, but all dead ends :shrug:
I did some searching and found this:
Question
I have a long delay when closing applications using hooks by clicking the x button in the titlebar. If I close the application via another event (button click) for example, that works fine.
Answer
It’s a known bug of Microsoft. It has to do with the Windows themes. If you disable the Windows themes, the problem goes away. Another choice is to have the hook code run in a secondary thread.

I’ll have a shot at it…
