I have the following line of code on the On_Load of a form containg a treeView Control
Set nodMRUExplorer = tvwMRUExplorer.Nodes.Add(strRelative, tvwChild, strFolderKey, rst.Fields(t + 2), "Folder")
This has been working fine for a year or two. I have been making some changes to the database and am now getting a 'Variable not defined' error on 'tvwChild'.
As far as I can tell this has never been defined elsewhere in the code. I have checked that the reference to 'Tree Control 1.0 Type Library' exists. I think the main thing that I have changed is that I have re-defined the list of top level folders. I have also added a reference to ADO 2.7 where it used to only use DAO 3.6, so it now uses both in the same procedure.
I know this is maybe a bit vague, but hopefully someone might be able to spread some light.
