What can I do with a SQLResource?

Question

I'm tasked with making a new resource.  Looking at the code for some of the existing resources, I see code that I tried to emulate, so I have something like this:

Set SQLResource = NetPerfMon.NewSQLResource
	SQLResource.SQL="Select NodeID, Caption, GroupStatus, AvgResponseTime, PercentLoss From Nodes' Order By IP_Address Desc"
	SQLResource.Filter=Resource.GetProperty("Filter")
	SQLResource.Execute

GetServerStat = SQLResource.GetProperty("GroupStatus")

The thing is, this doesn't just give me what is in the table column GroupStatus...it gives me that, wrapped in an <img> tag.

I was wonder if there's any doc on what all you can do with a NetPerfMon.NewSQLResource.  I'd like to not have to log in to the database myself in my resource, but I may need to, if NetPerfMon.NewSQLResource is doing magic behind the scenes that I don't know about.

Thanks,

Kevin
