The problem here is that on Windows the WM_LBUTTONUP message *is* swallowed when it terminates a drag and drop operation. The real problem is probably not to get in this LISTVIEW_TrackMouse in the first place.
I'm not sure I follow. If I understood the code right, when there is a real drag-and-drop event, we *do* swallow the WM_LBUTTONUP message like Windows does. That's the "ReleaseCapture(); return 1;" block which my patch doesn't affect.
I do not think so: it is inside a "if (msg.message == WM_MOUSEMOVE)" block.
What I changed was the "never mind, the mouse button was pressed, but it wasn't a drag-and-drop after all" part. But I could certainly have missed something, can you explain further?
Drag&drop is normally ended releasing the mouse button : WM_LBUTTONUP message. Hence the break and it will be affected by your patch.
But I am only assuming that what I see here, is the same as what you see. If you run your program with native comctl32, do you see the message pump (the peekmessage's) in action? In my case I only see it with built-in comctl32.
