Is it possible to use a VirtualRecordSet with a table that does NOT contain a PrimaryKey? Even to be able to display data in Read-Only format would be great.

Yes you can display data from a table that does not contain a primary key (by specifying null as the primary field) - however there are some limitations with what you can do. Without a primary key VDO is unable determine whether two records in different recordsets are actually the same. This may mean for instance when you change the sort order in a Grid control that the selection is not maintained.
