In sample it doesn't work. what's with MDI i send you Matt? Is it some help? I am switching to Win32Lib now, I'll have to reWrite my editor, but it will be worth it.I'll have some troubles because GetWindowLong(DATA) is already taken in Win32Lib. There's no sense in not using it and writing my own library.

I know that you're not switching to win32lib, but the drag and drop does work for me (and for others, as far as I know). What it doesn't do is change the mouse cursor when this happens (also, the demo only allows you to drag from a listview). To give you a brief description of how I do it: An LVN_BEGINDRAG notification is sent to the parent window through a WM_NOTIFY message. I use this to store the selection in sequence dragData, in this format: dragData = { id, { selection1, selection2, ... } } Then, in SubProc, when the left mouse button is released (WM_LBUTTONUP), I check to see if there is data that's been stored. If so, I call the onDragAndDrop proc for the control and clear dragData. If there is no proc for that control, I simply clear dragData. To do the same, allowing a treeview to be the source, you'd need to check for TVN_BEGINDRAG notifications, and do the same thing. Matt
