vb2012列表框ListBox与 复选列表框CheckedListBox问题如何在弹出form2显示

建一个form1，一个ListBox1，一个CheckedListBox1，一个Button1。建一个form2，一个TextBox1。
我想要的结果是列表框选择了AAAA后的Aaaa，然后弹出提示“这是Aaaa的结果”，但弹出的都是Caaa的结果这是怎么回事？你能帮我修改一下行吗？
我设计的语句如下：
1、双击form1空白处把一下代码复制粘贴
Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        ListBox1.Items.Add("AAAA")
        ListBox1.Items.Add("BBBB")
        ListBox1.Items.Add("CCCC")
    End Sub

    Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ListBox1.Click
        CheckedListBox1.Items.Clear()
        Select Case ListBox1.SelectedIndex
            Case 0
                CheckedListBox1.Items.Add("Aaaa")
                CheckedListBox1.Items.Add("Abbb")
                CheckedListBox1.Items.Add("Accc")
                CheckedListBox1.Items.Add("Addd")
            Case 1
                CheckedListBox1.Items.Add("Baaa")
                CheckedListBox1.Items.Add("Bbbb")
                CheckedListBox1.Items.Add("Bccc")
                CheckedListBox1.Items.Add("Bddd")
            Case 2
                CheckedListBox1.Items.Add("Caaa")
                CheckedListBox1.Items.Add("Cbbb")
                CheckedListBox1.Items.Add("Cccc")
                CheckedListBox1.Items.Add("Cddd")
        End Select
    End Sub
2、双击Button1输入一下代码
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        If (CheckedListBox1.GetItemChecked(0)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Aaaa的结果"
        End If
        If (CheckedListBox1.GetItemChecked(1)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Abbb的结果"
        End If
        If (CheckedListBox1.GetItemChecked(2)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Accc的结果"
        End If
        If (CheckedListBox1.GetItemChecked(3)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Addd的结果"
        End If
        If (CheckedListBox1.GetItemChecked(0)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Baaa的结果"
        End If
        If (CheckedListBox1.GetItemChecked(1)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Bbbb的结果"
        End If
        If (CheckedListBox1.GetItemChecked(2)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Bccc的结果"
        End If
        If (CheckedListBox1.GetItemChecked(3)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Bddd的结果"
        End If
        If (CheckedListBox1.GetItemChecked(0)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Caaa的结果"
        End If
        If (CheckedListBox1.GetItemChecked(1)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Cbbb的结果"
        End If
        If (CheckedListBox1.GetItemChecked(2)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Cccc的结果"
        End If
        If (CheckedListBox1.GetItemChecked(3)) = True Then
            Form2.Show()
            Form2.TextBox1.Text = "这是Cddd的结果"
        End If

    End Sub
End Class
不知道错在哪里
