Adding and Deleting data group records and ZoneRunner records via PowerShell

I'll keep looking at it. I've been experimenting for a couple days now and can't seem to get it right. I've tried loading it into a List, I've paused the execution to view the data structures and it's all really confusing... Actually, here's the code I posted in the other forum (thought it was already here...):

Interfaces interfaces = new Interfaces();

string[] view = { "external" };

ManagementViewZone[] viewZones = interfaces.ManagementZone.get_zone_name(view);

ManagementZoneInfo[] zoneInfo = interfaces.ManagementZone.get_zone(viewZones);

ManagementCNAMERecord record = new ManagementCNAMERecord();

record.cname = "test";

record.domain_name = "st.int";

record.ttl = 3600;

interfaces.ManagementResourceRecord.add_cname(viewZones, record);

Thanks! Tony
