If Not ctnPast Is Nothing AndAlso Not ctnPast.Equals(e.Node) Then
ctnPast.NodeFont = New Font(ctnPast.NodeFont.OriginalFontName, ctnPast.NodeFont.Size, sOldStyle)
End If
sOldStyle = e.Node.NodeFont.Style
ctnPast = e.Node
e.Node.NodeFont = New Font(e.Node.NodeFont.OriginalFontName, e.Node.NodeFont.Size, FontStyle.Bold)
End Sub
Dim sOldStyle As New FontStyle
Private ctnPast As TreeNode = Nothing
