*******************************************************************************************
*使用本CLASS可以管理并在asp页里面注册你的DLL
*本CLASS在WIN 2K上测试通过
*注：使用本CLASS需要先建立一个xml文件。文件如下.打开记事本将如下3行存为*.XML文件
*
*    <?xml version="1.0" encoding="gb2312" standalone="yes"?>
*    <Dll列表>
*    </Dll列表>
*
*------------------------------------------------------------------------------------------
*范例：
*    dim objRegsvr32
*    set objRegsvr32 = new Regsvr32
*    with objRegsvr32
*        if .LoadXml("../MyDll.xml") then
*            call Response.Write("XML文件加载错误")
*            set objRegsvr32 = nothing
*            Response.End
*        end if
*        select case .AddNode("F:\web\cw31072\dll\test\MyClass.dll" , true) '添加新条目并注册DLL
*            case 1
*                call Response.Write("条目已经添加进XML文件！并成功注册DLL啦！")
*            case 0
*                call Response.Write("条目已经添加进XML文件！但注册DLL时失败！")
*            case -1
*                call Response.Write("XML文件里已经有该条目！该DLL也已经注册的了！")
*        end select
*        ..........................
*    end with
*            
*    '本CLASS非常简单，里面还有些方法，我就不举例了,看看就知道了。日后你可以打开
*    '该XML文件看你曾经注册过和待注册的DLL列表。
*    'XML文件里每个条目如下：<Dll 是否已经注册="1">F:\web\cw31072\dll\test\MyClass.dll</Dll>
*    'F:\web\cw31072\dll\test\MyClass.dll就是你DLL文件的路径
*    '是否已经注册="1"就是该DLL已经注册过，=“0”就是还没有注册呢！
