I have a treeview control that receives A-Z and 0-9 as a key. The help defines key as string (Optional. A unique string that can be used to retrieve the Node with the Item method.). When I pass a number (in quotes), it seems to think it is numeric and, even though it defines it as a string, throws an OLE Exception and crashes.
Does anybody know how to force a number as a string to an external procedure?

TIA,
