VO Namespace |  |
This namespace contains all the VO SDK Classes, such as DbServer, DataWindow, SQLSelect etc.
If you enable the compiler option to search inside "Implicit Namespaces" (/ins) then you will not have to include a USING VO statement in your code.
The compiler will then automatically find the classes.
The Runtime will also respect these implicit namespaces, so CreateInstance(#DbServer) will also be able to find the DbServer class inside the VO namespace.
