    Hello...

    I am working on a treeview control window and I would like to know how I can refresh the expand sign in front of it. If I add a new item into an existing item, the + sign do not show. I must double-click the item (expand it) for it to refresh...

    Thanx...

    There is a property where + sign is always shown and so you need to set that property

    Is it a property or a style ? I'm using plain win32, not MFC...

    I checked all the TVS_ and TVIF_ and none seems to be the right one... Guess it's back to digging in the MSDN doc...

    No, it has nothing to do with the style.
    Your code is just wrong.

    This code should help you.

    Code:
    	HTREEITEM hitem = tree.InsertItem(_T("Shabbir"));
	tree.InsertItem(_T("Another one"),hitem);
	tree.Expand(hitem,TVE_EXPAND);
    tree is a CTreeCtrl object
