BasicFillSymbolClass Class

Basic fill symbol object.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.


The BasicFillSymbol is used to create a basic fill symbol comprised of a FillPattern.

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
