If you have MDI form you can implement following methods…

Private Sub cmdBack_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdBack.Click
        Try
            Dim PrevForm As Form = Nothing
            For Each ChildForm As Form In Me.MdiChildren
                If ChildForm.Equals(Me.ActiveMdiChild) Then
                    If Not IsNothing(PrevForm) Then
                        Me.ActivateMdiChild(PrevForm)
                        PrevForm.Focus()
                        Exit For
                    End If
                End If
                PrevForm = ChildForm
            Next
            PrevForm = Nothing
        Catch ex As Exception

        End Try
    End Sub

And

Private Sub cmdForward_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdForward.Click
    Try
        Dim NextForm As Form = Nothing
        For Each ChildForm As Form In Me.MdiChildren.Reverse
            If ChildForm.Equals(Me.ActiveMdiChild) Then
                If Not IsNothing(NextForm) Then
                    Me.ActivateMdiChild(NextForm)
                    NextForm.Focus()
                    Exit For
                End If
            End If
            NextForm = ChildForm
        Next
        NextForm = Nothing
    Catch ex As Exception

    End Try
End Sub

To do the same…this will allow you to do exact what you want provided you following MDI child form hierarchy.
