This is very cool code !!Help me a lot
I need some time to study
Thank you again

Updated Code to using SetWindowSubclass() instead of setwindowlong

This allows us to pass the ID of the dummy control through the pData Variable which cleans up the subclass procedure a bit

spudw2k · March 29, 2018

Neat approach. I was looking for a way to implement looking for the $WM_CONTEXTMENU notification instead of listening specifically for the Right-Click or Shift+F10 inputs. That way they (along with the application/menu key) would work without special checks. My quick implementation was producing two menu pop-ups though and I'm not sure why.

Bilgus · March 29, 2018

@spudw2k If you are just wanting some control over the context menu this example is probably a bit much

since its meant to get KeyUp events before the listview has a chance to eat the message

Instead THIS might be a bit better
