ASP网站制作之Running An ASP Script As A Windows N...
当然了,现在国内CRM厂商的产品与其说是CRM,但从至少从我的角度分析上来看,充其量只是一个大型的进销存而已了,了解尚浅,不够胆详评,这里只提技术问题window SUMMARYThis tutorial will guide you through the steps of setting up and configuring a Windows NT Server or Workstation to execute an ASP script as a service. This will let you execute an ASP script without a user being logged on to the server, thus allowing you to use the ASP technology as a tool for automatic file processing or similar.
REQUIREMENTS
For this setup to work, the server must have the following software installed:
An ASP compliant web server. For instance, Microsoft Internet Information Server (IIS) version 3.0 or higher.
A webbrowser. For instance, Microsoft Internet Explorer.
The Windows NT Ressource Kit or at least the ServAny/InstSrv utilities available separately.
When doing all the following, you must be logged on as Administrator.
THE SCRIPT
The ASP script you want to run as a service should be written as plain ASP as you would normally do. Although, in case you want the script to "loop", you should make sure, that you output the appropriate HTML to initiate a reload of the script. This should look something like this:
<%
[ Perform whatever task you need ]
%>
<html>
<head>
<meta http-equiv="refresh" content="60; url=myScript.asp">
</head>
<body>
...
</body>
</html>
Generally, you would not generate any output, as the script will run in the background, not having anything to present to a user.
The HTML above assumes that the name of the script is myScript.asp and will reload the script (execute it) every 60 seconds.
Copy the script file to your webserver so it is accessible within the webserver namespace. From now on, I assume that you put it in the webserver root directory, so it is accessible via
http://localhost/myScript.asp
Eventually, test it using the webbrowser to make sure everything works as planned.
INSTALLING THE SERVICE
Setting up the service is pretty straight-forward if you follow the guideline provided with the NT Ressource Kit. Anyway, the following will guide you through just the nessecary steps.
We need the following files from the NT Ressource Kit:
instsrv.exe Utility to install Windows NT services
srvany.exe A service that will run any application
Although its optional, I recommend putting both files in your System32 directory. Now, start up a command prompt and execute this:
instsrv myAspService srvany.exe
A new service named "myAspService" is now available through the Control Panel -> Services applet. Of course, you can provide any name you like.
CONFIGURING THE SERVICE
Now we need to configure the newly installed service to actually execute the script. As seen above, we need some host application to make the HTTP request - namely a webbrowser. In other words, we need to configure the service to execute the webbrowser with the appropriate URL as a parameter.
To configure the service, first open the Services applet in Control Panel. Locate the new service, double-click it, and make sure it is set to "Automatic" startup. Close the Control Panel applet.
Start up the registry editor (either regedit.exe or regedt32.exe).
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
Locate the name of your new service. Under this key, create a new key called "Parameters".
Under this new key, create the following two value/data pairs, both of type String/REG_SZ.
Value name: Application
Data: c:\Program Files\Plus!\Microsoft Internet\iexplore.exe
Value name: AppParameters
Data: http://localhost/myScript.asp
Of course, you must do any appropriate changes to paths and names in order to fit your system setup and installations paths.
Close the registry editor.
TESTING THE SERVICE
To test the entire setup, reboot the server. Afterwards, go to Control Panel -> Services and verify, that the service is running.

ASP也是这几种脚本语言中最简单易学的开发语言。但ASP也是这几种语言中唯一的一个不能很好支持跨平台的语言。 因为ASP脚本语言非常简单，因此其代码也简单易懂，结合HTML代码，可快速地完成网站的应用程序。 从事这个行业，那么你可以学ASP语言，简单快速上手，熟练dreamweav排版，写asp代码，熟练photoshop处理图片，打好基础就行了 掌握asp的特性而且一定要知道为什么。 不是很难但是英文要有一点基础网上的教程很少有系统的详细的去买书吧,另不用专门学习vb关于vbscript脚本在asp教材都有介绍 ASP（ActiveServerPages）是Microsfot公司1996年11月推出的WEB应用程序开发技术，它既不是一种程序语言，也不是一种开发工具，而是一种技术框架，不须使用微软的产品就能编写它的代码，能产生和执行动态、交互式、高效率的站占服务器的应用程序。 弱类型造成潜在的出错可能：尽管弱数据类型的编程语言使用起来回方便一些，但相对于它所造成的出错几率是远远得不偿失的。 代码的可重用性差：由于是面向结构的编程方式，并且混合html，所以可能页面原型修改一点，整个程序都需要修改，更别提代码重用了。 ASP的语言不仅仅只是命令格式差不多，而是包含在<%%>之内的命令完全就是VB语法。虽然ASP也是做为单独的一个技术来提出的，但他就是完全继承了VB所有的功能。
