下面是添加记录的代码。请教修改记录的代码。
Private Sub cmdAdd_Click()
    Dim sc As Integer

        If Not (Testtxt(txtNo.Text) Or Testtxt(txtName.Text) Or Testtxt(txtSex.Text) Or Testtxt(txtBookTime.Text) Or Testtxt(txtTel.Text) Or Testtxt(txtEnrolTime.Text)) Then
            MsgBox "带 * 号为必填项", vbOKOnly + vbExclamation, "警告"
            txtNo.SetFocus
        Exit Sub
        End If
            sc = MsgBox("确实要添加这条记录吗？", vbOKCancel, "提示信息")
        If sc = 1 Then
            Dim conn As New ADODB.Connection
            Dim rs As New ADODB.Recordset
