在试用中运行 总会有一些异常出现 代码的不严谨 或者数据的格式 都会导致项目卡死在那 在大量数据递交的时即使不出错 在任务管理器中也可能显示窗口不响应

举例说明一下 同一段数据 一样的执行代码 在不同的机子上 一个报错 一个正常

代码如下:

Dim sd As WinForm.DateTimePicker
Dim ed As WinForm.DateTimePicker
sd = e.Form.Controls("DateTimePicker1")
ed = e.Form.Controls("DateTimePicker2")
Dim cpbh As String = e.Form.Controls("项目").Value

Dim filter As String = "1=1"
If sd.Value <> Nothing Then
    filter &= " And 出车日期 >= \'" & sd.value & "\'"
End If
If ed.Value <> Nothing Then
    filter &= " And 出车日期 <= \'" & ed.value & "\'"
End If
If cpbh <> "" Then
    filter &= " And [项目] Like \'%" & cpbh & "%\' "
End If
If ed.value = Nothing AndAlso sd.value = Nothing Then
    filter &= " And 出车日期 = \'" & Date.today & "\'"
End If
DataTables("配载订单").LoadFilter=filter
DataTables("配载订单").Load
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree("配载订单", "车牌|司机|项目")
trv.Nodes.Insert("所有订单",0)

我把#号改成 \' 又报

这是我第一次自己做开发 好多语法 都不会 期间一直都是红袍版主在无私奉献 在此表示感谢 , 现在也已经提交试用 出于谨慎 公司决定试用之后才购买开发版 可能在众多的用户中 我只不过是一个还未入门的使用者

可我真想好好运用好这样的软件 虽坎坷 路还在

一直也不知道该怎样去规范代码的严谨使项目能正常进行 烦请红袍版主再次帮忙 怎样完善

日期的问题，设置一下其计算机

我试一下

另外这段代码报未将对象引用至对象实例

Dim Result As DialogResult
Result = MessageBox.Show("确定要退出吗?", "确认提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question)
If Result = DialogResult.OK Then
    Dim dr As DataRow
    Dim hyzh As String =Forms("主界面").Controls("姓名").Text----------------要读取的是另一个窗口中的控件 ,不是本窗口
    hyzh = hyzh.Trim(" ", "登","录","账","号",":","[","]")
    dr = DataTables("账户管理").Find("[用户账号] = \'" & hyzh & "\' ")
    dr("用户状态") = False
    SystemReady = False
    e.form.Close()
    Syscmd.Project.Exit(True)
    SystemReady = True
   
   
   
End If

    Dim hyzh As String = vars("账号") \'用一个变量在登陆的时候记录账号信息啊
    dr = DataTables("账户管理").Find("[用户账号] = \'" & hyzh & "\' ")

    If dr is Nothing Then

msgbox("没找到用户")

    Else

\'其它操作

    End If

还有个问题 我想请教 就是在出现未响应或者卡死时怎样关闭项目 是否只能在任务管理器中结束 ?

红版 为了不重复导入 引用你以前帮我写的代码 我把导入改为:

Dim dlg As new OpenFileDialog
If dlg.ShowDialog = DialogResult.OK Then
    Dim App As New MSExcel.Application
    try
        Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(dlg.FileName)
        Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets("计划表")
        Dim Rg As MSExcel.Range = Ws.UsedRange
        Dim ary = rg.value
       
        Tables("配载订单").ResumeRedraw()
        Tables("配载订单").StopRedraw()
        Dim nms() As  String = {"项目","下单日期","MK号","DO号","城市","客户","送货地址","物料代码","数量","体积","重量","承运商","司机","车牌","车数","车型","出车日期"}
        Dim count As Integer = 0
        Dim ls As new List(of Row)
        Dim dic As new Dictionary (Of DataRow, Row)
       
        For Each r As Row In Tables("计划表").Rows
            Dim filter As String = "1=1"
            For Each dc As String In nms
                If r.IsNull(dc) Then
                    filter &= " and " & dc & " is null"
                Else
                    Dim c As Col = Tables("配载订单").Cols(dc)
                    If c.IsNumeric Then
                        filter &= " and " & dc & " = " & r(dc)
                    ElseIf c.IsBoolean Then
                        If r(dc) = True Then
                            filter &= " and " & dc & " = true"
                        Else
                            filter &= " and " & dc & " = false"
                        End If
                    ElseIf c.IsDate Then
                        filter &= " and " & dc & " = #" & r(dc) & "#"
                    Else
                        filter &= " and " & dc & " = \'" & r(dc) & "\'"
                    End If
                End If
            Next
            Dim dr As DataRow = DataTables("配载订单").find(filter)
            If dr Is Nothing Then
                ls.Add(r)
                count += 1
            Else
                dic.add(dr, r)
            End If
           
        Next
        For n As Integer = 2 To ws.UsedRange.Rows.Count -1
            Dim r As  Row = Tables("配载订单").AddNew()
            For  m As  Integer = 0 To nms.Length - 1
                If Tables("配载订单").Cols(nms(m)).IsDate Then
                    Dim d As Date
                    If Date.TryParse(ary(n,m+1), d)
                        r(nms(m)) = d
                    End If
                Else
                    r(nms(m)) = ary(n,m+1)
                   
                End If
            Next
        Next
        Tables("配载订单").ResumeRedraw()
        msgbox("共有 "& count &" 条数据导入" )
       
    catch ex As exception
        msgbox(ex.message)
        app.quit
    End try
End If

Tables("配载订单").save
e.Form.Controls("提示").Text = "正在导入,请稍后..."
Application.DoEvents()
e.Form.Controls("提示").Text = "已经导入完成."
e.Form.TimerInterval = 5000
e.Form.TimerEnabled = True

点导入时 提示没有名为"计划表"的table 计划表是外部表  要怎样写才能访问到它 另外我不知道我这样套用代码是否可行

上传例子测试。
