Question

I am just porting a project from VB6 to VB.NET with the help of the Microsoft Upgrade Wizard.

One form was automatically upgraded to

Friend Partial Class frmAudFeedSentenceEdit
    Inherits System.Windows.Forms.Form

But when I add a new form to a new project in VB.NET, it is declared as

 Public Class frmAudFeedSentenceEdit

(without the Inherits System.Windows.Forms.Form).

Which one is correct, please?

Answer 1

When you make a form using Visual Studio, it will put the form information into 2 separate files.

The part you’re seeing:

Public Class frmAudFeedSentenceEdit

Is just the declaration in the main file, where you will normally work.

However, there is a second file created (frmAudFeedSentenceEdit.Designer.vb) which will have:

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class frmAudFeedSentenceEdit
    Inherits System.Windows.Forms.Form

As you can see, it’s still a Partial Class, but the Inherits statement is placed in the designer-generated file for you.

You can see this if you look in the Class View window, browse to your form, and double click on InitializeComponent() (as this Sub is defined in the designer file).
