Select Case e.Path
    Case "upload.htm"
        Dim wb As New weui
        wb.AddForm("","form1","receive.htm")
        With wb.AddInputGroup("form1","ipg1","文件上传")
            With .AddUploader("ABC128","照片",True)
                .AllowDelete = True '允许删除
                .Incremental = True '允许重复选择文件或连续拍照
            End With
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "button").Attribute= "" '调用js函数上传
        End With
        wb.AddToast("","tst1", "正在上传",1)
        wb.AddToast("","tst2", "上传成功",0)
        wb.AddToast("","tst3", "上传失败",0).Icon= "warn"
        wb.AppendHTML("<script src='./lib/ajaxform.js'></script>") '引入脚本文件
        e.WriteString(wb.Build) '生成网页
    Case "receive.htm"
        For Each key As String In e.Files.Keys

For Each fln As String In e.Files(key)

messagebox.show(fln)
                e.SaveFile(key,fln,"d:\web\uploadfiles\" & fln) '保存接收到的文件
            Next
        Next
        e.WriteString("OK")
End Select

以上代码，得出结果fln = abc 应该fln = ABC 才对

也就是，本来是大写的，现在变成了小写

请问怎么设置，让大小写不改变？
