detect mouse event on node of a treeview

[Sam]

Hi,
I'd like to get the selected node when the user select a node in my
treeview. I know how to get the selected node, what I don't know is how
to detect that the user has selected a new node.

What methods should I use ?
thx

I basically used a static variable to keep the old value of the
selected node and check to see if the new selected node was the same as
the old node. If not then I know they selected a new node.

If Not CurrentNode Is LastNode Then
LastNode = CurrentNode
If Not CurrentNode Is Nothing Then
MsgBox(CurrentN ode.Text)

thanks to both of you
finally here is what i've done

Private Sub tvRelations_Aft erSelect(ByVal sender As System.Object,
ByVal e As System.Windows. Forms.TreeViewE ventArgs) Handles
tvRelations.Aft erSelect

If tvRelations.Sel ectedNode.Nodes .Count = 0 Then
txtTable1.Text = tvRelations.Sel ectedNode.Paren t.ToString
txtTable2.Text = tvRelations.Sel ectedNode.ToStr ing
End If
End Sub
