This section describes the differences between VB6 and .NET controls and the problems you can find in migrating VB6 applications with user-interface. The differences that are common to most controls are described in the Controls (general) section.

For a list of differences between VB6 and VB.NET language, see here.

Unless otherwise stated, VB Migration Partner fully supports all the Visual Basic 6 features mentioned in this page. It is worth noticing that names of properties and methods are preserved, which ensures that those even late-bound references work correctly after the migration to VB.NET. For more information, please read the manual and the knowledge base section.

DirListBox control

List, ListCount, and ListIndex properties

The Upgrade Wizard converts these properties into the DirList, DirListCount, and DirListIndex properties of the Microsoft.VisualBasic.Compatibility.VB6.DirListBox control.

VB Migration Partner supports the original List, ListCount, and ListIndex properties, to ensure that migrated code works as intended even if the control is accessed in late-bound mode.

Scroll event

The Scroll event isn’t supported under .NET and it can only be approximated by trapping the SelectedIndexChanged event and by subclassing the window that is created when the dropdown list appears.

VB Migration Partner fully supports this event.
