You use different methods for calling member functions in a CTreeCtrl object depending on how the object was created:
If the tree control is in a dialog box, use a member variable of type
CTreeCtrlthat you create in the dialog box class.If the tree control is a child window, use the
CTreeCtrlobject (or pointer) you used to construct the object.If you're using a
CTreeViewobject, use the function CTreeView::GetTreeCtrl to get a reference to the tree control. You can initialize another reference with this value or assign the address of the reference to aCTreeCtrlpointer.
