Turn off layer fields in Arcpy

[MichaelHarrop]

Hi,

We have a number of mxds which we use for map services. Within them we have a number of fields which we want to turn off e.g. object_id, shape_length etc. Is it possible to switch these off in arcpy so that they are not visible when identify is use or can it only be done by going into the mxd and un-ticking them?

Thanks

The FieldInfo() class has a setVisible(index, visible) parameter.
