So the old One to Many Label Parser evidently uses VB6 (http://resources.esri.com/help/9.3/arcgisdesktop/com/samples/cartography/labeling_and_annotation/onetomanylabels/d5daadc3-3514-4572-b8e9-8f2c7aeede07.htm) and therefore doesn't appear to work in ArcMap v10. Does anyone have any ideas how this tool could be recreated in ArcGIS 10 (ArcMap)?
This idea has been merged with Support labeling on related fields.
And for those who don't know, the One to Many Label Parser allowed the labeling, via an extra tab in the Label expression dialog of an ArcMap layer, of features that had related records contained in a table hooked up to a the feature class by a relationship class. For records in the parent feature class that had more than 1 corresponding record in the join table, the join table field or fields (you could choose up to 2 fields to label) that you would use for labeling would stack. It was a fairly handy tool and I'm not sure what the best alternatives in v10 would be.
And it would be cool if this could all work when you publish to an MSD for ArcGIS Server as well.
