代码如下：
Private Sub Form_Load()
Dim nd As Node
Dim i As Integer
Dim j As Integer
Set nd = Tv1.Nodes.Add(, , "pj", "设备配件列表")
Dim rs1 As ADODB.Recordset
Dim rs2 As ADODB.Recordset
Set rs1 = New ADODB.Recordset
rs1.Open "select distinct pjmc from basic", cn, 3, 1
rs1.MoveFirst
i = 1
Do While Not rs1.EOF
Set nd = Tv1.Nodes.Add("pj", tvwChild, "p" & i, rs1.Fields("pjmc"))
Set rs2 = New ADODB.Recordset
rs2.Open "select distinct guig from basic where pjmc = '" & nd.Text & "' ", cn, 3, 1
If Not rs2.EOF Then
rs2.MoveFirst
j = 1
Do Until rs2.EOF
Set nd = Tv1.Nodes.Add("p" & i, tvwChild, , rs2!guig)
rs2.MoveNext
j = j + 1
Loop
End If
Set rs2 = Nothing
rs1.MoveNext
i = i + 1
Loop
End Sub
