MORE INFORMATION

Steps to Reproduce the Behavior

1. Create a new Windows application by using Microsoft Visual Basic .NET or Microsoft Visual Basic 2005 or Microsoft Visual C# .NET.
   
   By default, Form1 is created.
2. Right-click Form1, and then click View Code.
3. Replace the existing code with the following code:
   
   Visual Basic .NET or Visual Basic 2005 Code

   Public Class Form1
       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 by using the Windows Form Designer.  
       'Do not modify it by using the Code editor.

           Me.ListBox1.Size = New System.Drawing.Size(120, 95)

           Me.CheckedListBox1.Name = "CheckedListBox1"
           Me.CheckedListBox1.Size = New System.Drawing.Size(120, 94)
           Me.CheckedListBox1.TabIndex = 1
           '
           'Form1
           '
           Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
           Me.ClientSize = New System.Drawing.Size(352, 266)
           Me.Controls.Add(Me.CheckedListBox1)
           Me.Controls.Add(Me.ListBox1)
           Me.Name = "Form1"
           Me.Text = "Form1"

   Note You must change the code in Visual Basic 2005. By default, Visual Basic creates two files for the project when you create a Windows Forms project. If the form is named Form1, the two files that represent the form are named Form1.vb and Form1.Designer.vb. You write the code in the Form1.vb file. The Windows Forms Designer writes the code in the Form1.Designer.vb file. The Windows Forms Designer uses the partial keyword to divide the implementation of Form1 into two separate files. This behavior prevents the designer-generated code from being interspersed with your code.

4. In Solution Explorer, right-click Form1, and then click View Designer.
   
   In the Form1 Design view, notice the first item in CheckedListBox1.
5. On the Debug menu, click Start to run the application.
   
   Notice the first item in CheckedListBox1.
