Description

Indicates the CLSID of the labeling properties used to label the layer.

Remarks

ArcGIS provides two engines that can be used for labeling, the ESRI Standard Labeling Engine and the ESRI Maplex Labeling Engine.

You can use AnnotationPropertiesID determine which engine is being used by the layer to label features.

ESRI Standard Labeling Engine: GUID for LabelEngineLayerProperties = "{01004145-0D1C-11D2-A26F-080009B6F22B}"
ESRI Maplex Labeling Engine: GUID for MaplexLabelEngineLayerProperties="{20664808-0D1C-11D2-A26F-080009B6F22B}"

You should not set this property. The labeling engine set for the map controls how each layer in the map will be labeled. To set this use IMap::AnnotationEngine.  When the label engine is changed, the label properties of the all layers in the map will automatically be changed to properties of the new label engine.

If have a standalone layer that is not in a map, you can translate the properties to the other label engine by using IAnnotationPropertiesConverter on the coclass MaplexAnnotationPropertiesConverter.
