老师，请教两个问题：

1、如何设置 AddPageTitle 添加的标题的 字体 及字号？谢谢！

2、下面的函数怎么无法调用？错在哪里？谢谢！

函数名 logon

Dim e As RequestEventArgs = args(0)
Dim wb As New weui
\'身份验证
Dim Verified As Boolean \'用于标记用户是否通过了身份验证
Dim UserName As String = e.Cookies("username") \'从cookie中获取用户名
Dim Password As String = e.Cookies("password") \'从cookie中获取用户密码
If e.Path = "logon.htm" \'如果是通过登录页面访问,从PostValues即可中提取用户名和密码
    If e.PostValues.ContainsKey("username") AndAlso e.PostValues.ContainsKey("password")  Then
        UserName = e.PostValues("username")
        Password = e.PostValues("password")
    End If
End If
For Each dr As DataRow In DataTables("用户管理").DataRows
    If UserName = dr("Name") AndAlso Password = dr("config").Contains(MD5Encrypt(Password)) Then
        Verified  = True
    End If
Next
If Verified AndAlso e.Path = "logon.htm"  Then \'如果用户访问的是登录页,且身份验证成功
    wb.AppendCookie("username",UserName) \'将用户名和密码写入cookie
    wb.AppendCookie("password",Password)
    wb.InsertHTML("<meta http-equiv=\'Refresh\' c>") \'直接跳转到首页
    e.WriteString(wb.Build) \'生成网页
    Return ""  \'必须的
ElseIf Verified = False AndAlso e.Path <> "logon.htm" Then \'如果用户身份验证失败,且访问的不是登录页面
    wb.InsertHTML("<meta http-equiv=\'Refresh\' c>") \'那么直接跳转到登录页面
    e.WriteString(wb.Build) \'生成网页
    Return"" \'必须的
End If
\'开始生成网页
Select Case e.path
    Case "logon.htm" \'登录页面
        wb.AddPageTitle("","pageheader","从业人员健康体检自助系统")
        If e.PostValues.ContainsKey("username") AndAlso e.PostValues.ContainsKey("password")  Then \'判断是否是验证失败后的重新登录
            wb.AddTopTips("","toptip1","用户名或密码错误!").msec = 2000 \'如果用户通过登录按钮访问,则给用户一个2秒的提示.
        End If
        wb.AddForm("","form1","logon.htm")
        With wb.AddInputGroup("form1","ipg1")
            .AddInput("username","户名","text")
            .AddInput("password","密码","password")
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "登录", "submit")
        End With
    Case "exit.htm" \'退出登录
        wb.DeleteCookie("username") \'清除cookie中原来的用户名和密码
        wb.DeleteCookie("password")
        wb.InsertHTML("<meta http-equiv=\'Refresh\' c>") \'那么直接跳转到登录页面
    Case "", "default.htm" \'首页
        wb.AddPageTitle("","pageheader","销售系统","由湛江辉迅基于Foxtable开发")
        With wb.AddGrid("","g1")
            .Add("c1","增加订单", "./images/button.png").Attribute = ""
            .Add("c2","客户管理", "./images/cell.png", "http://www.foxtable.com")
