Ms Access Treeview Error Invalid Key
If you hover over nodParent while in debug mode, it will show the TEXT of the node. That would open up a lot of possibilities for this treeview control. I assume that it is the plain ID as number without a leading character. > What is the best way to determine that Item 1 is the second node belonging to As to the actual implementation, I can't really say anything generic. this contact form

I dunno if I explained it very well... But works with Set nodParent = objTree.Nodes(vbNullString & varReportToID) 'where varReportToID="a1"? something like this:!--c1-->CODEDim tv As TreeViewDim lngColor As LongSet tv = Me.WorkOrderTreeViewrst.MoveFirstDo Until rst.EOF'It may be faster to open a recordset with ONLY WorkOrder nodes in it, but if you use BuildKey() and ParseKey() My keys take the form: K123|256|156 The numberics are the Autoid's from the table(s) that produced the node. --- I have done alot of work with TreeViews, and
I expect that whenever you are in a situation where the method expects a Variant/string/long, such as when doing debug.print, it will use the default method. With that, it is my guess that, with varReportToID holding the string value of "a1", you would be able to do this ...

Is there a restriction like .Key property should be different from .Text property for a particular node, for example?
I was really wondered about how VBA deals with different data types without explicit conversion and now I can see where I can meet an obstacle.
