The following Microsoft Visual Basic for Applications (VBA) macro shows how to use the BreakLinkToData method to break the link between a shape and a data row in a data recordset.
Before running this macro, place a shape on the page, add at least one data recordset to the DataRecordsets collection of the document, and use any linking method to link the shape to a data row in the data recordset you most recently added to the collection. Alternatively, you could link the shape to a data row by dragging the row from the External Data window onto the shape in the Visio user interface. Then select the linked shape.
