当多用户几乎同时点下单时，在服务端几乎同时执行了以下代码，好多的变量，是不是我整个思路错了，还一直停留在之前电脑客户端上开发的状态，如果真错了，请老师告诉我应该如何处理，谢谢！
Dim e As RequestEventArgs = args(0)
Dim wb As New WeUI
Dim nms() As String
If e.PostValues("合同类型") = "常规" Then
nms = {"公司","工程名称","工程地点","浇注部位","开盘时间","混凝土标号","塌落度","浇注方法","计划方量","需方联系人","需方电话","业务员","业务员电话"} '不能为空的列名数组,去除运输里程
Else
nms = {"公司","工程名称","工程地点","浇注部位","开盘时间","混凝土标号","塌落度","浇注方法","计划方量","运输里程","需方联系人","需方电话","业务员","业务员电话"} '不能为空的列名数组
End If
For Each nm As String In nms
If e.PostValues.ContainsKey(nm) = False Then '生成错误提示页
With wb.AddMsgPage("","msgpage","下单失败", nm & "项目不能为空!")
.icon = "Warn" '改变图标
.AddButton("btn1","返回").Attribute = ""
End With
e.WriteString(wb.Build)
Return "" '必须返回
End If
Next
Dim dr As DataRow = _dt生产任务通知.AddNew()
Dim dr1 As DataRow
dr1 = _dt销售合同.SQLFind("审核 = 1 And 合同 = '" & e.PostValues("合同") & "'")

End If
End If
'保存并生成增加成功提示页面
dr.save()
With wb.AddMsgPage("","msgpage","下单成功", "单号:" & dr("单号")) '生成成功提示页
Dim htm As String
