请教一个问题textbox.text 在类方法引用问题
运行提示hairclor=tbhair.Text对非共享成员的引用要求对象引用，是什么原因，类方法不能直接引用还是那里出错，请帮帮忙？<HTML>
<HEAD>
<script language="VB" runat="server">
CLASS cx
public hairclor as string
public eyeclor as string
public birthday as date
sub setmyself(Sender As Object, E As EventArgs)
hairclor=tbhair.Text
eyeclor=tbeye.Text
birthday=date(tbbir.Text)
end sub
end class
sub btSubmit_click(Sender As Object, E As EventArgs)
dim week as integer
week=birthday.dayofweek
response.write(hairclor&eyeclor）
end sub
</script>
</HEAD>
