* The new studio is not always as smart as the older ones.. it is much more pernicky when it can't find something. For example if you did not include all of the subclass definitions in your view, then the VDF12+ studio whines alot and can't draw your view in the designer. However if you open such a view in -say VDF10.1- then it draws perfectly. What gives? Well .. let's not go there and tell you instead that you can have the VDF10.1 Studio write out all those missing include files by just saving a space in the good ol' Studio. | * The new studio is not always as smart as the older ones.. it is much more pernicky when it can't find something.

* Move class definitions that ended up in your views and reports and put them in their own files. The studio doesn't like this type of construct. If you nested your class definition in your view, it is likely to cause your view not to be able to render itself in the designer. | * Move class definitions that ended up in your views and reports and put them in their own files.

* Use the latest migration wizard you can get your hands on. The VDF14.1 wizard will catch more as the VDF14.0 one. Even if you are eventually going to migrate to VDF14.0, use the one from 14.1 for refining your code. | |||
