Is this test enough to determine if user is dragging?

Question

I want to determine if user is dragging listview item, by pressing ( and holding ) left mouse button.

I am processing WM_MOUSEMOVE[^] and testing if user is dragging with if( wParam & MK_LBUTTON ).

Does this condition give me 100% accurate info about user dragging the mouse, or are there other pitfalls ( when testing like this ) I am unaware of?

You should consult this fine article on our site. Pay attention to the handling of the notifications. :-O

That code has serious flaw when user selects multiple items, as was reported in one of the messages. I have managed to write my own code that seems to remedy the problem. I just want to remove variable that detects dragging, hence this question.

Thanks for answering.
