海马汽车经销商管理系统技术解析（四）新增预约

新增预约单

预约新增就是录入客户的基本信息、预约到厂时间、添加预约明细信息预约维修项目、所需配件等信息。界面如（图一）、（图二）所示：



（图一）



（图二）



因该下拉框用自动完成源功能，所以可以通过下拉框选择，也可手动输入后再选，如果系统没有该车辆的信息，可跳转到客户档案新增界面新增。

从界面上看到的控件有：

空间名称	说明
文本框（TextBox）	编辑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， 还可以设置控件的事件。
日期控件（DataTimepPicker）
(NumericUpDown)
下拉框（ComboBox）
复选框（CheckBox）
表格（DataGridView）
选项卡（TabControl）
按钮（Button）
（ToolStrip）

功能实现
1、设置表格控件（DataGridView）的属性。Load事件里面写。

dgvSettel.AutoGenerateColumns = false;//不允许自动添加列
dgvSettel.ReadOnly = true;//只读，不能编辑

2、绑定下拉框（可自动完成源）
第一步：数据库存储过程

IF(@TYPE='FRM_YuYueGuanLi_Insert_Load_Selectchepaihao')
BEGIN
SELECT     CarNewsID,LTRIM(RTRIM (LicensePlateNumber))AS LicensePlateNumber
FROM         BM_CarNewsList
WHERE BM_CarNewsList.IfEffective=1
END

第二步：逻辑层（BLL）

//查询系统所有的车牌号
[OperationContract]
public DataSet FRM_YuYueGuanLi_Insert_Load_Selectchepaihao()
{
SqlParameter[] mySqlParameters =
{
new SqlParameter("@TYPE",SqlDbType.Char),
};
mySqlParameters[0].Value = "FRM_YuYueGuanLi_Insert_Load_Selectchepaihao";
DataTable dt = myDALMethod.QueryDataTable("预约管理_FRM_YuYueGuanLi_Insert", mySqlParameters);
DataSet ds = new DataSet();
ds.Tables.Add(dt);
return ds; //返回一个数据集，就是数据表的集合

第三步：界面层（UIL）。Load事件里写代码。

BLL海马汽车销售系统.预约管理.FRM_YuYueGuanLi_Insert.FRM_YuYueGuanLi_InsertClient myFRM_YuYueGuanLi_InsertClient =
new BLL海马汽车销售系统.预约管理.FRM_YuYueGuanLi_Insert.FRM_YuYueGuanLi_InsertClient();

DataTable dtChePaiHaoMa = myFRM_YuYueGuanLi_InsertClient.FRM_YuYueGuanLi_Insert_Load_Selectchepaihao().Tables[0];//查询数据
cboLicensePlateNumber.DataSource = dtChePaiHaoMa;//给下拉框绑定数据源
cboLicensePlateNumber.DisplayMember = "LicensePlateNumber";//设置下拉框显示的值
cboLicensePlateNumber.ValueMember = "CarNewsID";//设置下拉框的属性
cboLicensePlateNumber.DropDownStyle = ComboBoxStyle.DropDown; //或者是 ComboBoxStyle.Simple ，当为DropDownList时，ComboBox不能输入任何文本，因此自动完成源无效
string[] str = new string[dtChePaiHaoMa.Rows.Count];//实例化数组，指定长度
for (int x = 0; x < dtChePaiHaoMa.Rows.Count; x++)//循环表
{
str[x] = dtChePaiHaoMa.Rows[x]["LicensePlateNumber"].ToString();//把显示的值加进数组
}
cboLicensePlateNumber.AutoCompleteSource = AutoCompleteSource.CustomSource;//指定源
cboLicensePlateNumber.AutoCompleteCustomSource.AddRange(str);//为源添加数据
cboLicensePlateNumber.AutoCompleteMode = AutoCompleteMode.Suggest;//为用户完成源并显示下拉框给用户选择

3、检测时间和计算时间
第一步：界面层（UIL）日期控件（DateTimePicker）值改变事件或控件NumericUpDown值改变事件

private void dtpYuYueShiJian_ValueChanged(object sender, EventArgs e)
{
double dblGongShi = 0;
for (int j = 0; j < dgvBespeakServiceItem.Rows.Count; j++)//循环预约维修项目表
{
dblGongShi += Convert.ToDouble(dgvBespeakServiceItem.Rows[j].Cells["标准工时"].Value);//把每项维修项目的工时相加
}
DateTime datYuYueShiJian = dtpBespeakTime.Value.Date.AddHours(Convert.ToDouble(nudhour.Value)).AddMinutes(Convert.ToDouble(nudminute.Value));
if (datYuYueShiJian > DateTime.Now)//如果预约来厂时间晚于当前时间
{
txtBookingCarDeliveryTime.Text = datYuYueShiJian.AddHours(dblGongShi).AddMinutes(30).ToString();//対预约交车时间赋值
DataTable dtTiXing = myFRM_YuYueGuanLi_InsertClient.FRM_YuYueGuanLi_Insert_SelectShangBanShiJian().Tables[0];//提取系统设置的提前提醒时间数
//txtBespeakWarnTime.Text = Convert.ToString(datYuYueShiJian.AddHours(Convert.ToDouble(dtTiXing.Rows[0]["DefaultValue"])));//对预约提醒时间赋值
double dblTiQian = Convert.ToDouble(datYuYueShiJian.Hour) - Convert.ToDouble(dtTiXing.Rows[0]["DefaultValue"]);
//对预约来厂时间进行赋值。
txtBespeakWarnTime.Text = Convert.ToString(datYuYueShiJian.Date.AddHours(Convert.ToDouble(datYuYueShiJian.Hour) - Convert.ToDouble(dtTiXing.Rows[0]["DefaultValue"])).AddMinutes(datYuYueShiJian.Minute));
}
else//如果预约来厂时间早于当前时间
{
dtpBespeakTime.Value = DateTime.Now.Date;//当前时间的日期部分
//nudhour.Value = DateTime.Now.Hour;
//nudminute.Value = DateTime.Now.Minute;
MessageBox.Show("预约时间不能早于当前时间！", "提示");
}
}

4、提取车辆信息和车主信息
第一步：数据库存储过程

IF(@TYPE='FRM_YuYueGuanLi_Insert_cboChePaiHaoMa_SelectedIndexChanged')
BEGIN
SELECT     BM_CarNewsList.CarOwnerNewsID, BM_CarOwnerNewsList.CarOwnerCode, BM_CarOwnerNewsList.MobilePhone, BM_CarNewsList.VINCode, BM_CarNewsList.BuyCarDate,
BM_CarNewsList.BodyworkColour, BM_CarNewsList.CarModelsCode, BM_CarOwnerNewsList.CarOwnerName
FROM         BM_CarNewsList INNER JOIN
BM_CarOwnerNewsList ON BM_CarNewsList.CarOwnerNewsID = BM_CarOwnerNewsList.CarOwnerNewsID
WHERE  BM_CarNewsList.CarNewsID=@CarNewsID
END

第二步：逻辑层（BLL）

//查询车辆信息

mySqlParameters[1].Value=intCheLiangXinXiID;
DataTable dt = myDALMethod.QueryDataTable("预约管理 _FRM_YuYueGuanLi_Insert", mySqlParameters);
DataSet ds = new DataSet();
ds.Tables.Add(dt);
return ds; //返回一个数据集
}

第三步：界面层（UIL）

BLL海马汽车销售系统.预约管理.FRM_YuYueGuanLi_Insert.FRM_YuYueGuanLi_InsertClient myFRM_YuYueGuanLi_InsertClient =
new BLL海马汽车销售系统.预约管理.FRM_YuYueGuanLi_Insert.FRM_YuYueGuanLi_InsertClient();
private void cboChePaiHaoMa_SelectedIndexChanged(object sender, EventArgs e)
{

//查询车辆所有的预约信息
DataTable dtYongHuChengXinDu = myFRM_YuYueGuanLi_InsertClient.FRM_PeiJianDingDan_Insert_SelecteYongHuChengXinDu(Convert.ToInt32(cboLicensePlateNumber.SelectedValue)).Tables[0];
if (dtYongHuChengXinDu.Rows.Count > 0)//如果该车辆有预约信息存在
{
for (int j = 0; j < dtYongHuChengXinDu.Rows.Count; j++)//循环表
{
if (dtYongHuChengXinDu.Rows[i]["FailCause"].ToString() != "")//如果该条单据预约失败
{
intNemBer++;//加一
}
}
if (intNemBer / dtYongHuChengXinDu.Rows.Count > 0.3)//如果预约失败比例大于30%
{
MessageBox.Show("此人多次爽约，请注意！");
}
}
//查询该车辆的信息
DataTable dt = myFRM_YuYueGuanLi_InsertClient.FRM_YuYueGuanLi_Insert_cboChePaiHaoMa_SelectedIndexChanged(Convert.ToInt32(cboLicensePlateNumber.SelectedValue)).Tables[0];
//给各个空间赋值
txtCarOwnerName.Text = dt.Rows[0]["CarOwnerName"].ToString();
