ASP网站制作之VB中经由过程WMI掌握DNS办事器，可在ASP中调...

只要你想学,就没什么优缺点,上面那位大哥已经把网上的评论说了,但我认为想学哪个都一样,不然它就不可能在当今时代数字艺术方面存活到今天dns办事器|掌握   在VB中要利用Scripting API for WMI，必需援用 Microsoft WMI Scripting V1.1 Library

上面引见Scripting API For WMI的几个对象

SWbemLocator――用于获得SWbemServices对象，他代表了当地或近程盘算机上名字空间的一个毗连。
SWbemService――代表名字空间的一个毗连，可用于处置它的部件
SWbemObject――代表一个独自的类界说或一个对象实例
SWbemOjbectSet――包含SWbemObject的纠合

上面是DNS WMI Provider的几个对象
MicrosoftDNS_Zone――用于办理DNS办事器上的区域的类
MicrosoftDNS_AType，MicrosoftDNS_CNAMEType,MicrosoftDNS_MXType等等――办理DNS Server上的各类资本纪录

具体的参考请见MSDN，我用的是VS.NET2003带的MSDN
Scripting API for WMI的途径是 MSDN Library--设置和体系办理--Windows Management Instrumentation(WMI)--SDK文档--WMI Reference--Scripting API For WMI

DNS WMI Provider的途径是 MSDN Library--收集和目次办事--域名体系(DNS)--SDK文档--DNS WMI Provider--DNS WMI Provider Reference--DNS WMI Classes


上面是代码完成

需求援用Microsoft Scripting Runtime和Microsoft WMI Scripting V1.1 Library，只是示例了A、MX、和CName纪录的操作，还可以扩大其他资本纪录的操作，也能够加上区域的操作，参考MSDN就能够了

  对于中小型web应用来说,php有很强的竞争力,linux+apache+mysql+php(lamp)的组合几乎可以胜任绝大多数网站的解决方案,对于大型应用来讲,对于系统架构要求更高,需要有成熟的框架支持,jsp的struts是个不错的框架,国内介绍它的资料也非常多,应用逐渐广泛起来。asp就不用说了，
