TreeView_CreateDragImage
HIMAGELIST TreeView_CreateDragImage(
    HWND hwndTV,
    HTREEITEM hitem
);		
Creates a dragging bitmap for the specified item in a tree view control. The macro also creates an image list for the bitmap and adds the bitmap to the image list. An application can display the image when dragging the item by using the image list functions. You can use this macro or send the TVM_CREATEDRAGIMAGE message explicitly.
Returns the handle to the image list to which the dragging bitmap was added if successful, or NULL otherwise.

hwndTV
Handle to the tree view control.
hitem
Handle to the item that receives the new dragging bitmap.

If you create a tree view control without an associated image list, you cannot use the TreeView_CreateDragImage macro to create the image to display during a drag operation. You must implement your own method of creating a drag cursor.
