Public method GetFormattedMessage Gets the error message for an HRESULT and formats the message by populating parameters with the supplied values.
Public methodStatic member GetFormattedMessageEx Gets the error message for an HRESULT and formats the message by populating parameters with the supplied values.
Public method GetHashCode (Inherited from Object.)
Public method GetType (Inherited from Object.)
Protected method MemberwiseClone (Inherited from Object.)
Protected method SetErrorInterface(IDTSComponentEvents100) Specifies the IDTSComponentEvents100 instance that the ErrorSupport class will use to raise messages.
Protected method SetErrorInterface(IDTSComponentMetaData100) Specifies the IDTSComponentMetadata100 instance that the ErrorSupport class will use to raise messages.
Protected method SetErrorInterface(IDTSInfoEvents100) Specifies the IDTSInfoEvents100 instance that the ErrorSupport class will use to raise messages.
Public method ToString (Inherited from Object.)

Remarks

Although the data flow component developer can raise errors, warnings, and other events by calling the Fire<X> methods of the IDTSComponentMetaData100 interface, the Fire<X> methods of the ErrorSupport class provide additional value by retrieving descriptive messages that correspond to known COM HRESULTs returned by Integration Services components written in native code. Use the ErrorSupport property of the PipelineComponent base class to obtain an ErrorSupport object for this purpose.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
