WCF广州本田整车销售系统技术解析（三） 订单新增功能实现分析

订单新增功能实现分析
订单新增功能主要是录入一条新的订单数据以及订单的明细。订单编号、订单号、发票号自动生成。在司机姓名改变的时候联系电话会随着司机姓名改变而改变，打开货物列表，选择需要哪些车辆双击就可以添加到订单明细列表，填写其它的订单信息之后 ，点击保存就可以完成订单的新增操作！

新增订单如图（图7）所示



（图7）

从界面上可以看到我们这里用到的控件有

控件名称	说明
日期控件（DateTimePicker）	控件可以在工具箱直接拖动至窗体，拖至窗体后右击属性可以修改控件的样式和各种属性，还可以编辑事件。
下拉框（ComboBox）
文本（TextBox）
按钮（Button）
表格（DataGridView）
菜单控件（toolStrip）

表与关系如图（图8）所示

一、订单编号、订单号、发票号自动生成实现

订单编号、订单号、发票号自动生成如图（图9）

1、数据库的存储过程

--查询最大单据数
if(@Type='frm_DingDanGuanLi_Insert_SelectZuiDaDanHaoShu')

BEGINTRAN
UPDATEMaxNumberStatisticsList --修该MaxNumberStatisticsList
SETNumbers=Numbers+1  --设置Numbers+1

FROMMaxNumberStatisticsList   --从MaxNumberStatisticsList查询
COMMITTRAN

[b][b][b][b][b]1、数据库的存储过程[/b][/b][/b][/b][/b]

第三步：根据一条货运单明细的数量来生成车辆
