Zoom to Selected Features Extent in a Layer within a Map Service

Question

Hi,

I have a map document, and it has layers coming from non-cached map services. The map services can have features selected.

How do I zoom to the selected features for a layer (i.e. a map service) in arcpy?

The script, map services and map document are all ArcGIS 10 SP2.

Thanks.

Shot in the dark, but did you try setting "False" to get the geometric extent instead of symbolized extent?

d.extent = l.getExtent(False)

I doubt that would be an issue, but like I said, shot in the dark.

Another thing, will there always be a selection? There is another method to get an extent of selected features.
d.extent = l.getSelectedExtent()

You could also try getting just the layer you want instead of going through all of them recursively, 
l = arcpy.mapping.ListLayers(mxd, "Rail Roads", d)[0]

Thanks.

I tried it, still have the same results (i.e. the  l.getExtent() part crashes if the layer is part of a non-cached map service).

In fact, I tried it in the Python window within ArcMap with

m = arcpy.mapping.MapDocument("CURRENT")

and it did not work.

Make sure in this line you use the full path the the map document: m = arcpy.mapping.MapDocument("test3.mxd")

For example: m = arcpy.mapping.MapDocument(r"C:\Data\MapDocs	est3.mxd")

The way you have it right now, it is unsure of where to find that document.
