接收上传的文件

假定有下图所示的一个表：

希望设计一个下图所示的录入界面，能拍照并上传照片：

HttpRequest事件代码：

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)
            Return '这里必须返回
    End Select
End If
Dim wb As New weui
Select Case e.Path
    Case "addnew.htm"
        If e.PostValues.Count = 0 Then
            wb.AddForm("","form1","addnew.htm")
            With wb.AddInputGroup("form1","ipg1","增加员工")
                .AddInput("姓名","姓名","Text") '前一个"姓名"是ID,后一个"姓名"是标题
                .AddInput("年龄","年龄","number")
                .AddSelect("学历","学历","大专|本科|硕士|博士")
                .AddUploader("up1","照片",True) 'True表示允许上传多个文件
            End With

            With wb.AddButtonGroup("form1","btg1",True)
                .Add("btn1", "确定", "submit")
            End With

            e.WriteString(wb.Build)
        Else
            Dim nms() As String = {"姓名","年龄","学历"}
            Dim dr As DataRow = DataTables("员工").AddNew()
            For Each nm As String In nms
                dr(nm) = e.PostValues(nm)
            Next
            For Each key As String In e.Files.Keys
                If key = "up1" Then
                    For Each fln As String In e.Files(key)
                        e.SaveFile(key, fln, ProjectPath & "Attachments\" & fln)
                    Next
                    dr.Lines("照片") = e.Files(key)
                End If
            Next
            '保存并生成增加成功提示页面
            dr.save()
            With wb.AddMsgPage("","msgpage","增加成功", "好好学习,天天向上") '生成成功提示页
                .AddButton("btn1","继续增加","addnew.htm")
            End With
            e.WriteString(wb.Build)
        End If
End Select

================================================================

加粗的按钮代码，改成增强型uplaod的代码怎么改？

        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "button").Attribute= "" '调用js函数上传
        End With
