INgAttributeFormatted Interface

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Schematics Extension.

[Visual Basic 6.0]

This code sample shows how you can create a new INgAttributeFormatted interface for an element type that will be used afterwards by a textual property to display a label for each element of this type. The label displayed for each element will be a formatted string that will concatenate the "Identifier: " string with the element OBJECTID field value. As the final label must use the OBJECTID database field returned by the query set for the element type as a formatted parameter, you will begin to create the attribute field related to this OBJECTID database field.
