今天又继续研究了一下代码。有个不懂的地方要问老师

那就是怎么没见给二维码扫描按钮设置事件代码呢？

Select Case e.Path
    Case "test.htm",""
        Dim wb As New weui
        wb.AppendHTML("<script src='http://res.wx.qq.com/open/js/jweixin-1.0.0.js'></script>",True) '引入JS-SDK库
        wb.AppendHTML("<script src='./lib/jssdk.js'></script>") '引入脚本文件
        '在页面注入权限验证配置
        Dim st As New Date(1970,1,1,8,0,0)
        Dim appid As String = "wxa31aba4cd83af57e" 'CorpID
        Dim timestamp As Integer = CInt((Date.Now - st).TotalSeconds()) '时间戳
        Dim noncestr As String = Rand.NextString(16) '随机字符
        Dim url As String = e.Request.URL.ToString '当前页面地址
        Dim signature As String = Functions.Execute("GetJsSignature", noncestr, timestamp, url) '生成权限验证签名
        Dim cfg As String = "wx.config({appId:'{0}',timestamp:{1},nonceStr:'{2}',signature:'{3}',jsApiList:['scanQRCode']});"
        wb.AppendHTML("<script>" & CExp(cfg,appid,timestamp,noncestr,signature) & "</script>",True)
        '开始正常生成网页内容
        wb.AddForm("","form1","test.htm")
        With wb.AddInputGroup("form1","ipg1","产品输入")
            .AddInput("product","产品","text")
            With .AddInputCell("ic1")
                .AddLabel("lbh","编号",0)
                .AddInput("number","text",1)
                .AddVcodeButton("scan","扫码输入",2) '扫描二维码的按钮怎么没有设置事件代码呢
            End With
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "submit")
        End With
        e.WriteString(wb.Build) '生成网页
End Select
