ASP Quick Reference from W3Schools. Print it, and fold it in your pocket.
ASP scripts are surrounded by <% and %>. To write some output to a browser:
<% response.write("Hello World!") %>
The default language in ASP is VBScript. To use another scripting language, insert a language specification at the top of the ASP page:
Request.QueryString is used to collect values in a form with method="get". Information sent from a form with the GET method is visible to everyone (it will be displayed in the browser's address bar) and has limits on the amount of information to send.
Request.Form is used to collect values in a form with method="post". Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.
A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user's computer. Each time the same computer requests for a page with a browser, it will send the cookie too.
The Response.Cookies command is used to create cookies:
Note: The Response.Cookies command must appear BEFORE the <html> tag!
The "Request.Cookies" command is used to retrieve a cookie value:
response.write("Firstname=" & fname)
You can insert the content of one ASP file into another ASP file before the server executes it, with the #include directive. The #include directive is used to create functions, headers, footers, or elements that will be reused on multiple pages
<!--#include file ="somefile.inc"-->
Use the virtual keyword to indicate a path beginning with a virtual directory. If a file named "header.inc" resides in a virtual directory named /html, the following line would insert the contents of "header.inc":
<!-- #include virtual ="/html/header.inc" -->
Use the file keyword to indicate a relative path. A relative path begins with the directory that contains the including file. If you have a file in the html directory, and the file "header.inc" resides in html\headers, the following line would insert "header.inc" in your file:
<!-- #include file ="headers\header.inc" -->
Use the file keyword with the syntax (..\) to include a file from a higher-level directory.
The Global.asa file is an optional file that can contain declarations of objects, variables, and methods that can be accessed by every page in an ASP application.
Note: The Global.asa file must be stored in the root directory of the ASP application, and each application can only have one Global.asa file.
The Global.asa file can contain only the following:
Application and Session Events
In Global.asa you can tell the application and session objects what to do when the application/session starts and what to do when the application/session ends. The code for this is placed in event handlers. Note: We do not use <% and %>, to insert scripts in the Global.asa file, we have to put the subroutines inside the HTML <script> tag:
<script language="vbscript" runat="server">
' some code
' some code
' some code
' some code
It is also possible to create objects with session or application scope in Global.asa by using the <object> tag. Note: The <object> tag should be outside the <script> tag!
<object runat="server" scope="scope" id="id"
A TypeLibrary is a container for the contents of a DLL file corresponding to a COM object. By including a call to the TypeLibrary in the Global.asa file, the constants of the COM object can be accessed, and errors can be better reported by the ASP code. If your Web application relies on COM objects that have declared data types in type libraries, you can declare the type libraries in Global.asa.
The Session object is used to store information about, or change settings for a user session. Variables stored in the Session object hold information about one single user, and are available to all pages in one application.
A group of ASP files that work together to perform some purpose is called an application. The Application object in ASP is used to tie these files together. All users share one Application object. The Application object should hold information that will be used by many pages in the application (like database connection information).
The Response Object is used to send output to the user from the server.
When a browser asks for a page from a server, it is called a request. The Request Object is used to get information from the user.
The Server Object is used to access properties and methods on the server.
