A tree is a recursive structure so the way to traverse a TreeView is almost always using recursion:

Private Sub Button1_Click(ByVal sender As Object, _
                          ByVal e As EventArgs) Handles Button1.Click
    Me.FindCheckedNodes(Me.TreeView1.Nodes)
End Sub
 
Private Sub FindCheckedNodes(ByVal nodes As TreeNodeCollection)
    For Each node As TreeNode In nodes
        If node.Checked Then
            MessageBox.Show(node.FullPath, "Checked")
        End If
 
        'This is the recursive call.
        Me.FindCheckedNodes(node.Nodes)
    Next
End Sub
