You should have an object reference to the DBCx Manager, and you can use that. Here's the code (including instanciating the Meta Manager):

* Setup the Dbcx Manager
oMeta = newobject('DBCXMgr', 'DBCXMgr.vcx', '', .F., lcMetaDataDir)
oMeta.SetDatabase(dbc())

* Get a property of a specific field
oMeta.dbcXGetProp(cFieldName, "FIELD", "WebControlType")

* Get an array of fields for a certain property
oMeta.dbcxGetAllobjects('field', @laFields, '', 'WebControlType', 'MyType')

That last line is pretty cool, it will get you an array of all the fields in the database where the WebControlType is "MyType"... at least I think I got the syntax right. Doug will probably correct me if I don't :-)
