Demonstration of clsObjectTable This simple MapObjects/Visual Basic project demonstrates many of the capabilities of the clsObjectTable object. The Full View, Zoom Out, and Pan/Zoom tools should be self explanatory. The Pole and Span tools are used for editing these features: Pole Left mouse - Selects a pole or adds one if none is found. Hold down to drag the selected pole and any attached spans. Right mouse - Deletes a pole and any attached spans. Span Left mouse - Click and drag to define the span line. When you lift up, it will search for poles at either end of the line. If poles are found, the line will snap to them and the span will be saved. Right mouse - Deletes a span. When a pole is selected, you can edit and update its attributes in the bottom frame. ---------- clsObjectTable is a front-end to a MapLayer that can read and write shapefile/SDE records as VB objects. The idea for this came from similar concepts in ARC/INFO version 8.0. Objects read and written with clsObjectTable must have the following three methods: ReadRecord - given a Recordset, populate the object with the values of the current record Spawn - return a new instance of the object class WriteRecord - given a Recordset, write the attributes of the object to the current record or a new record To operate, a clsObjectTable object must be given a MapLayer and a Prototype object. The Spawn method is used on the Prototype to generate instances of the feature object. clsObjectTable supports all of the MapLayer search methods (SearchByDistance, SearchExpression, SearchShape). Use the HasResultSet method to see if a search found any records. clsObjectTable also contains its own internal Recordset, so all of the Recordset management methods (EOF, MoveFirst, MoveNext) are also supported. Use ReadObject to retrieve objects from the MapLayer and WriteObject to send them back.
