( S$ |' u1 N+ V2 w 大家知道，脚本语言（包括javascript和VBscript语言等）经常会被植入网页之中（其中包括 HTML 页面客户机端和 ASP页面服务器端） 。对于植入 HTML 页面的脚本，其所需的解析引擎会由 IE 这样的网页浏览器载入；对于植入 ASP页面的脚本，其所需的解析引擎会由 IIS（ Internet Information Services）提供。而对于出现在 HTML 和ASP 页面之外的脚本（它们常以独立的文件形式存在），就需要经由 WSH 来 处理了。需要说明的是：WSH 要想正常工作，还要安装IE 3.0或更高版本的 IE，因为 WSH 在工作时会调用 IE 中的 VBScript 和 javascript 解析引擎。[未结束][iduba_page]在这些被植于网页的脚本语言中，绝大多数是与网络安全无关的。但也有少数别有用心的好事者，把一些严重危及网络安全的代码（我们常常称之为“恶意代码”，他们通常都要通过修改注册表达到“恶意”的目的！），混放在正常的脚本之中，常常让我们防不胜防。但是，如果我们了解一点关于脚本语言的知识，这些“伎俩”都是非常容易识破的。还是让我们从几个简单 的实例开始吧…… 3 l$ g3 }" a1 @# R* J8 [+ V' j3 x, w) _4 F5 D# u+ q! j

WSH可以处理脚本程序，怎样阅读和编写WSH的脚本源文件呢？只要你有一点Basic（会VB的编程更好，呵呵）语言的基础，学会看懂WSH脚本语言的程序并不是一件难事。去C:WINDOWSSAMPLESWSH目录以下将看看吧！里面提供了几类经典的脚本例子，而且分别提供了VBScript和 javascript两个版本，我们只要用记事本打开它们并仔细研究就不难学到一些基本的WSH应用。 ( s; `: s* t. n' e( d, q) t4 _; v8 j, m" W

A:This is similar to the *.js association problem. Some machines seem to,for some reason, lose their *.vbs association. It's not that the filesopen with dreamweaver or whatever -- it's that the machine just doesn'tknow how to run them. If you have a scheduled task, "Could not run"will appear in the status column., c o+ x3 b% i- @

So, you're a smart person andread through the FAQ. You find the *.js extension problem, and you trythat fix: you run it as "wscript c:\path\to cript.vbs". But that, inturn, produces a pop-up error, this time a "Windows Scripting Host"error: "There is no script engine for file extension '.vbs'." So, forsome reason, wscript doesn't even know what to do with *.vbs files. [, [( [4 V: \& j3 Z4 f, B% A* Z7 x) C+ m
The solution to this problem is to run the script as: 4 m' h( D- Z# W ! C0 F, {% Y1 S5 y3 O% h+ Pwscript //e:vbscript c:\path\to cript.vbs : S8 ^- o- E# d' O- v! q1 J0 o
The "//e:vbscript" tells wscript to use the vbscript engine to parse the script. It will then run correctly.2 H: s# ?3 p' D, c2 U
( R/ f9 O ]' s4 g! E4 n8 ^A few alternative solutions, perhaps easier are: $ _* j( Q8 {; n6 i4 |Renameit .vbe (VBScript Encoded Script File). Not sure if this is a bad idea,but it seemed to work for some scripts. Make a new association for VBS.Open up my computer, select Tools menu-> Folder Options, and go tothe File Types tab. There probably isn't a VBS association listed ifyou have this problem. Select New, type in VBS, and hitAdvanced>>. Then, from the pull-down menu, select "VBScriptScript File". Making this selection automatically takes care of theassociation, along with the //e:vbscript problem. This is probably the"correct" solution... ) y, `% i6 O# q: q2 YThis problems usually occurs only on WindowsXP machines, but the cause is not known.
