How are Visual Basic 6.0 Forms upgraded to VB.NET?
The upgrade wizard converts VB 6.0 forms (files with the file name extension .frm) to Windows Forms, the .NET Framework’s form development system, which uses classes in the System.Windows.Forms.Form namespace. Upgraded form files are saved with the file name extension .vb, like other Visual Basic .NET code files. Each Visual Basic 6.0 form’s properties, methods, and events (PME) is upgraded to an equivalent System.Windows.Forms.Form PMEs.
