以下是我用treeview控件按部门和员工显示设备领用情况代码.

Option Compare Database
    Dim rec As New ADODB.Recordset
    Dim recPlant As New ADODB.Recordset
    Dim nodindex As Node
    Dim keyDepa, strDepa
    Dim keyEm, strEm
    Dim keyPl, strPl
Private Sub Form_Load()
    AutoMxID
    ‘设置第一级"部门"
    rec.Open "qry部门_升序", CurrentProject.Connection, adOpenKeyset, adLockOptimistic, adCmdTableDirect
    For I = 0 To rec.RecordCount - 1
        Set nodindex = Treeview.Nodes.Add(, , "部门" & rec.Fields("depaID"), rec.Fields("depa"), "k1", "k2")
        rec.MoveNext
    Next
    rec.Close
    nodindex.Sorted = False
    ‘设置第二级"员工"
    ‘* ---------------------------
    rec.Open "qry员工_升序", CurrentProject.Connection, adOpenKeyset, adLockOptimistic, adCmdTableDirect
    For I = 0 To rec.RecordCount - 1
        Set nodindex = Treeview.Nodes.Add("部门" & rec.Fields("depaID"), tvwChild, "员工" & rec.Fields("emID"), rec.Fields("emName"), "k1", "k2")
        recPlant.Open "Select tblplant.plantid, tblplant.plant, tblplant.emid" & " FROM qry员工使用的设备" & " Where tblplant.emid = ‘" & rec.Fields("emID") & "‘", CurrentProject.Connection, adOpenKeyset, adLockOptimistic, adCmdTableDirect
        For N = 0 To recPlant.RecordCount - 1
            Set nodindex = Treeview.Nodes.Add("员工" & recPlant.Fields("emID"), tvwChild, "设备" & recPlant.Fields("PlantID"), recPlant.Fields("Plant"), "k1", "k2")
            nodindex.Sorted = True
            recPlant.MoveNext
        Next N
        recPlant.Close
        nodindex.Sorted = True
        rec.MoveNext
    Next I
    rec.Close
End Sub

Private Sub Treeview_NodeClick(ByVal Node As Object)
    Dim nodindex As Node
   点击事件为NodeClick
    If Node.Key Like "部门*" Then
        keyDepa = Mid(Node.Key, 3)
        strDepa = Node.Text: Me.申报部门 = strDepa
    End If
    If Node.Key Like "员工*" Then
        keyEm = Mid(Node.Key, 3)
        strEm = Node.Text: Me.申报员工 = strEm
    End If

    If Node.Key Like "设备*" Then
        keyPl = Mid(Node.Key, 3)
        strPl = Node.Text: Me.设备名称 = strPl: Me.设备编号 = keyPl
    End If
End Sub
