2. Some bits of a Visual Basic 6 application, like most APIs, can be easily migrated to VB.NET; other parts are not so straightforward. Which of the following will NOT have to be re-architected during a VB 6-to-VB.NET migration?
A) DHTML pages
B) ActiveX documents
C) OLE controls
D) ADO to ADO via Interop
A VB.6 migration is not entirely smooth sailing, said Keith Pleas in the SearchVB.com article, Webcast: How to upgrade legacy VB 6 applications. .NET Framework transactions must be done manually, while items like ActiveX documents, DHTML pages and OLE controls need a bit of re-architecting. ADO to ADO via Interop data access migration, though, is pretty straightforward.
