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.

[C#]

The following C# code illustrates how to acquire a reference of type IAnnotationEditExtension to the AnnotationEditExtension object.

public void GetAnnotationEditExtensionByCLSID()
{
  //You can get app from ICommand :: OnCreate() hook parameter
  UID editorUid=new UIDClass();
  editorUid.Value="esriEditor.Editor";
  IEditor editor=app.FindExtensionByCLSID(editorUid) as IEditor;

  UID extUid=new UIDClass();
  extUid.Value="esriEditor.AnnotationEditExtension";
  IAnnotationEditExtension annoExt=editor.FindExtension(extUid) as IAnnotationEditExtension;
}

[Visual Basic .NET]

The following VBNet code illustrates how to acquire a reference of type IAnnotationEditExtension to the AnnotationEditExtension object.

  Public Sub GetAnnotationEditExtensionByCLSID()
    'You can get app from ICommand :: OnCreate() hook parameter
    Dim editorUid As UID=New UIDClass()
    editorUid.Value="esriEditor.Editor"
    Dim editor As IEditor=TryCast(app.FindExtensionByCLSID(editorUid), IEditor)

    Dim extUid As UID=New UIDClass()
    extUid.Value="esriEditor.AnnotationEditExtension"
    Dim annoExt As IAnnotationEditExtension=TryCast(editor.FindExtension(extUid), IAnnotationEditExtension)
  End Sub
