Remarks
The MapServerLayer coclass allows users to display and query the contents of a data frame in a map document published through an ArcGIS Map Service, or directly from the map file.
A few notes concerning interfaces that MapServerLayer implements. The count on ICompositeLayer or ICompositeLayer2 may not match the actual number of sub layers represented in the Map Server Layer (see Count on ILayerDescriptions). This is because the count on ICompositeLayer or ICompositeLayer2 does not include members of composite layers that are embedded within the MapServerLayer. The count on ICompositeLayer or ICompositeLayer2 only counts the parent layer.
The values for the IGeoDataset properties Extent and SpatialReference will reflect the map units and spatial reference set in the data frame of the original map document that is bound to the Map Server object. These may not reflect the spatial reference of the layer's underlying data.
The following are not supported: LoadLayers on ILayerFactory, Brightness and Contrast on ILayerEffect and ShowTips and TipText on ILayer.
Working with Events
When working with MapServerLayer's default outbound interface in Visual Basic 6 declare variables as follows: Private WithEvents pMapServerLayer as MapServerLayer
