Description

A group is a window that draws a bordered line all around. This makes it draw a limiting placeholder for other controls. To indicate what it is used for, a group box may display a title, also referred to as its caption. Here is an example of a group box on a form:

To support group box, the .NET Framework provides the GroupBox class. At design time, to add a group box to your application, from the Containers section of the Toolbox, click GroupBox and click the form (or another container). To programmatically create a group box, you can create a handle to GroupBox, allocate memory for it using the new operator, and add it to the Controls collection of its container. Here is an example:

Imports System.Drawing
Imports System.Windows.Forms

Module Exercise

    Public Class Starter
        Inherits Form

        Private GrpHolder As GroupBox

        Dim components As System.ComponentModel.Container

        Public Sub New()
            InitializeComponent()
        End Sub

        Public Sub InitializeComponent()

            GrpHolder = New GroupBox()
            GrpHolder.Left = 22
            GrpHolder.Top = 18
            GrpHolder.Width = 120
            GrpHolder.Height = 58
            Controls.Add(GrpHolder)

        End Sub

    End Class

    Function Main() As Integer

        Dim frmStart As Starter = New Starter

        Application.Run(frmStart)

        Return 0
    End Function

End Module

This would produce:
