i done this with for loop

VB

Dim i As Integer
Dim str As String = ""

For i = 0 To ListBox1.SelectedItems.Count - 1
    str = str & " " & ListBox1.SelectedItems(i).ToString
Next
MessageBox.Show(str)

VB

Dim i As Integer
Dim str As String = ""

For i = 0 To CheckedListBox1.CheckedItems.Count - 1
    str = str & " " & CheckedListBox1.CheckedItems(i).ToString
Next
MessageBox.Show(str)
