    Is there a better way? Treeview [Resolved]

    I have two tables:

    tblClassification - id, classification
    tblSnipplets - id, classification, title, dateadded, code

    I have the key for the treeview classification because I can't use id for some reason. I am having problems when I click on the node I want view the info in some text fields. I think I have the key messed up. Any help would be greatly appreciated.

    Thanks

    Code:
    Private Sub initializeTree()
        tvwItems.ImageList = imgList
        
        Dim nodClass As Node
        Dim nodTitle As Node
        
        tvwItems.LineStyle = tvwRootLines
        tvwItems.Nodes.Clear
        
        'Initialize the recordsets
        Set rsClass = New ADODB.Recordset
        Set rsTitle = New ADODB.Recordset
    
        'Open the Class recordset
        strSQLClass = "SELECT id, classification FROM tblClassification ORDER BY classification"
        rsClass.Open strSQLClass, conTree, adOpenStatic, adLockOptimistic
        
        'set node for treeview
        If rsClass.RecordCount > 0 Then
            While Not rsClass.EOF
                Set nodClass = tvwItems.Nodes.Add(, , (rsClass.Fields("classification")), (rsClass.Fields("classification")), 1)
    
                'Opens the recordset for Title
                strSQLTitle = "SELECT id, title, classification, code, dateadded FROM tblSnipplets WHERE classification LIKE '" & (rsClass.Fields("classification")) & "%'"
                rsTitle.Open strSQLTitle, conTree, adOpenStatic, adLockOptimistic
                
                'set node for treeview
                If rsTitle.RecordCount > 0 Then
                    While Not rsTitle.EOF
                        Set nodTitle = tvwItems.Nodes.Add((rsClass.Fields("classification")), tvwChild, (rsTitle.Fields("title")), (rsTitle.Fields("title")), 2)
                        rsTitle.MoveNext
                        DoEvents
                    Wend
                End If
                rsTitle.Close
                
                rsClass.MoveNext
                DoEvents
            Wend
        End If
    End Sub
    
    Private Sub tvwItems_NodeClick(ByVal Node As MSComctlLib.Node)
        
    strNodeLabel = Node
    If Node.Image = 2 Then
        strSQLTitle = "SELECT * FROM tblSnipplets WHERE classification = '" & Me.tvwItems.SelectedItem.Key & "'"
        Set rsTitle = New ADODB.Recordset
        rsTitle.Open strSQLTitle, conTree, adOpenStatic, adLockOptimistic
        
        showData
        
        Set rsTitle = Nothing
    End If
        
    End Sub
