VBScript版代码高亮


'======================================
'代码高亮类
'使用方法:
'Set HL = New Highlight '定义类
'HL.Language = "vb" '指定程序语言,支持 VBS ,JS ,XML, HTML, SQL, C#, Java...等
'还可通过直接设置下列属性还设置相关关键字等
' Public Keywords '关键字
' Public Objects '对象
' Public SplitWords '分隔符
' Public LineComment '行注释
' Public CommentOn '多行注释
' Public CommentOff '多行注释结束
' Public Ignore '是否区分大小写
' Public CodeContent '代码内容
' Public Tags '标记
' Public StrOn '字符串标记
' Public Escape '字符串界定符转义
' Public IsMultiple '允许多行引用
'HL.CodeContent = "要高亮的代码内容"
'Response.Write(Hl.Execute) '该方法返回高亮后的代码
