I got it to work
However, I still need help with some API functions
In my code I am at the point where I know when
TVN_SELCHANGED has happened.
I want to go further and get its
NMTREEVIEW structure and from it, get the the
TVITEM both from itemOld and itemNew. Then, I want to get the handle of both these TVITEM structures and I should have everything I need to do what I intend to do.
Thanks for helping me!
