Rob,

I would do it this way :

Private currentTABIndex As Integer = 0
Private selectingTREE As Boolean

Private Sub TreeView1_AfterSelect(ByVal sender As System.Object, ByVal e 
As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect
        
        Select Case e.Node.Text
            Case "TAB 1"
                Me.selectingTREE = True
                Me.TabControl1.SelectedTab = Me.TabPage1
                Me.currentTABIndex = Me.TabControl1.SelectedIndex
            Case "TAB 2"
                Me.selectingTREE = True
                Me.TabControl1.SelectedTab = Me.TabPage2
                Me.currentTABIndex = Me.TabControl1.SelectedIndex
            Case "TAB 3"
                Me.selectingTREE = True
                Me.TabControl1.SelectedTab = Me.TabPage3
                Me.currentTABIndex = Me.TabControl1.SelectedIndex
            Case "TAB 4"
                Me.selectingTREE = True
                Me.TabControl1.SelectedTab = Me.TabPage4
                Me.currentTABIndex = Me.TabControl1.SelectedIndex
        End Select
    End Sub

Private Sub TabControl1_SelectedIndexChanged(ByVal sender As Object, ByVal 
e As System.EventArgs) Handles TabControl1.SelectedIndexChanged
        
        If Not Me.TabControl1.SelectedIndex.Equals(currentTABIndex) And 
Me.selectingTREE = False Then
            MessageBox.Show("Please select options from the tree, not the 
tabs.")
            Try
                Me.TabControl1.SelectedIndex = Me.currentTABIndex
            Catch
                'Handles invalid currentTABIndex 
            End Try
        Else
            Me.selectingTREE = False
        End If
    End Sub
