Dim fl As String = "d:\web\" & e.path
If filesys.FileExists(fl)
    Dim idx As Integer = fl.LastIndexOf(".")
    Dim ext As String  = fl.SubString(idx)
    Select Case ext
        Case ".jpg",".gif",".png",".bmp",".wmf",".js",".css" ,".html",".htm",".zip",".rar"
            e.WriteFile(fl)

        wb.AddForm("","form1","test.htm")
        With wb.AddInputGroup("form1","ipg1","查询条件")

        e.WriteString(wb.Build) '生成网页
    Case  "getProducts.htm"
        Dim vals As String
Dim cmd As new SQLCommand
cmd.C
cmd.CommandText=" elect t1.产品名称,t2.生产日期_开始,t2.规格 f  rom 质检报告主表 t2 inner join 成品有出厂检验 t1 on t1.编号=t2.编号 where t2.生产日期_开始= '"& e.PostValues("scrq") &"'"

 'MessageBox.Show(cmd.CommandText)
Dim dt As DataTable= cmd.ExecuteReader
        If e.PostValues.Count = 1 Then
            vals  = "|" & dt.GetComboListString("产品名称","生产日期_开始='" & e.PostValues("scrq") & "'")
        ElseIf e.PostValues.Count = 2 Then
            Dim Filter As String = "生产日期_开始='" & e.PostValues("scrq") & "' And 产品名称='" & e.PostValues("cpmc") & "'"
            vals = "|" & Dt.GetComboListString("规格", Filter)
        End If
        e.WriteString(vals)
End Select

 

上述代码在执行的时候  选择好了 生产日期后，在产品名称的下拉列表中可以有值，但不能选中

谢谢，问题已经找到

现在遇到 怎么把生成的pdf 推送给客户端

 

If r("单据状态")<>"" Then
    If r("报告类型")="包装油出厂检验报告" Then

Dim Book As New XLS.Book(drr("图章存储位置")& "Attachments\"& r("报告类型") &".xlsx")
 
         Dim fl As String = "d:\ "& "PDF"& format(now(),"yyMMdd")& Rand.Next(100) &".pdf"

        If r("质检员")="" Then
            MessageBox.Show("尚未制定质检员,请选择")
            Return 0
        End If
 
        book.AddDataTable("质检报告主表","pk","S   elect * from 质检报告主表 where 编号= '"& r("编号")&"'") '添加父表
        book.AddDataTable("质检报告附表","pk","S    elect * from 质检报告附表 where 编号= '"& r("编号") &"'") '添加子表
        book.AddDataTable("成品有出厂检验","pk","S    elect * from 成品有出厂检验 where 编号= '"& r("编号") &"'And 产品名称='"& Vars("pinming") &"' and 规格='"&  Vars("guige") &"'") '添加子表
        book.AddRelation("质检报告主表","编号","质检报告附表","编号") '建立关联
        book.AddRelation("质检报告主表","编号","成品有出厂检验","编号") '建立关联
        Dim Sheet As XLS.Sheet = Book.Sheets(0)
       
        Sheet(10,2).Value = New XLS.Picture(GetImage(r("质检员")))
        Sheet(10,7).Value =New XLS.Picture(GetImage(shqm))
        Book.Build() '生成细节区
        Sheet = Book.Sheets(0)
       
       
        'Dim dr As DataRow= DataTables("系统设置").Find("图章存储位置<>''")
        Sheet(Sheet.Rows.Count-7, 4).Value  = New XLS.Picture(GetImage(drr("质检公章")))
        
        Dim str As String
        book.Savetopdf(fl)
       e.WriteBook(fl,"PDF"& format(now(),"yyMMdd")& Rand.Next(100) &".pdf",False)
 
        'Proc.File = fl
        'Proc.Start()
         '
  
    End If
   
   
   
   
Else
   ' MessageBox.Show("请先审核单据在生成报告")
    Return 0
End If
e.Handled = True

 

代码在附件中

遇到问题如下

1、规格的值获取不到  Vars("gg") = e.PostValues("gg")

2、生成报告是否可以写在内  部函数中

3、生成的报告 能否下载

 4、

我做了简单的测试，excel可以生成网页，但不能下载，将生成报告语句在内部函数中调用 总是报错

十分感谢，程序可以执行了，但最大的问题就是在生成excel转网页的时候特别慢，好像是一笔一笔画出来一样，等两分钟的样子页面打开了，有些地方还不显示

想着实现 可以网页查看 也可以下载，
