Here is the code I've written and tested. If you create a new form and paste this code in, replacing all existing code.

To get this working for your own application may require a little bit of thought, but I've shown you all the principles behind what needs doing.

Code:
Public Class Form2
    Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

    Public Sub New()
        MyBase.New()

        'This call is required by the Windows Form Designer.
        InitializeComponent()

        'Add any initialization after the InitializeComponent() call

    End Sub

    'Form overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub

    'Required by the Windows Form Designer
    Private components As System.ComponentModel.IContainer

    'NOTE: The following procedure is required by the Windows Form Designer
    'It can be modified using the Windows Form Designer.  
    'Do not modify it using the code editor.
    Friend WithEvents Button1 As System.Windows.Forms.Button
    Friend WithEvents Button2 As System.Windows.Forms.Button
    Friend WithEvents ListBox1 As System.Windows.Forms.ListBox
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
        Me.Button1 = New System.Windows.Forms.Button
        Me.Button2 = New System.Windows.Forms.Button
        Me.ListBox1 = New System.Windows.Forms.ListBox
        Me.SuspendLayout()
        '
        'Button1
        '
        Me.Button1.Location = New System.Drawing.Point(8, 8)
        Me.Button1.Name = "Button1"
        Me.Button1.TabIndex = 0
        Me.Button1.Text = "Button1"
        '
        'Button2
        '
        Me.Button2.Location = New System.Drawing.Point(104, 8)
        Me.Button2.Name = "Button2"
        Me.Button2.TabIndex = 1

        Me.ListBox1.Enabled = False

        Me.ResumeLayout(False)

    End Sub

#End Region

        ' build a brush of that colour

        ' sort out our font - i.e. if it's an active item, make it bold...
        Dim myFont As Font

        If myObj.Active = True Then
            myFont = New Font(e.Font, FontStyle.Bold)
        Else
            myFont = e.Font.Clone
        End If

        ' draw the text in the correct colour; this also assumes that the property you want to show is called 'name'...
        e.Graphics.DrawString(myObj.Name.ToString, myFont, myBrush, rect.X + 1, rect.Y + 2)

        ' dispose of objects...
