4 GB of free hard-disk space for the installer and the temporary space for the installed image. For supported processors, refer the requirement specification for the respective Operating System. Facebook posts are not covered coldFusion the terms of Creative Commons.
Post questions and get answers from experts. For the programming language, see CFML. SOAP handling for both creating and consuming services – as an example, ASP. Other implementations of CFML offer similar or enhanced functionality, such as running in a . Java, and a syntax very similar to HTML. CFStudio provided a design platform with a WYSIWYG display. The Allaire company was sold to Macromedia, then Macromedia was sold to Adobe.
Earlier versions were not as robust as the versions available from version 4. 0, the engine had been re-written in Java and supported its own runtime environment, which was easily replaced through its configuration options with the runtime environment from Sun. 1 included the ability to code and debug Shockwave Flash. 1995-July-02: Allaire Cold Fusion version 1.
1996: Allaire Cold Fusion version 1. 1996-November: Allaire Cold Fusion version 2. 1997-June: Allaire Cold Fusion version 3. 1998-January: Allaire Cold Fusion version 3. Not needed if you already have Update 8 or later installed. 1 brought about a port to the Sun Solaris operating system.
Cold Fusion studio gained a live page preview and HTML syntax checker. First release from Macromedia after the Allaire Corporation acquisition. The last to be legacy coded for a specific platform. On January 16, 2001, Allaire announced a pending merger with Macromedia. Prior to 2000, Edwin Smith, an Allaire architect on JRun and later the Flash Player, initiated a project codenamed “Neo”. In June 2002 Macromedia released the version 6.
Adobe Flex 2 as well as more improvements for the CF Report Builder. Some of the new features are the CFPDFFORM tag, which enables integration with Adobe Acrobat forms, some image manipulation functions, Microsoft . An explicit “local” scope that does not require local variables to be declared at the top of the function. Implicit constructors via method called “init” or method with same name as CFC. New CFFinally tag for Exception handling syntax and CFContinue tag for Control flow. Tighter integration with Adobe Flex and Adobe AIR. In Memory Management – or Virtual File System: an ability to treat content in memory as opposed to using the HDD.
The lists above were obtained from the Adobe web site pages describing “new features”, as listed first in the links in the following list. CF10 was originally referred to by the codename Zeus, after first being confirmed as coming by Adobe at Adobe MAX 2010, and during much of its prerelease period. As of CF11, their use would not cause the CFLOG tag to fail. Aether is the Greek god of upper atmosphere. Component methods may be made available as web services with no additional coding and configuration.
All that is required is for a method’s access to be declared ‘remote’. Aside from SOAP, the services are offered in Flash Remoting binary format. Methods which are declared remote may also be invoked via an HTTP GET or POST request. Consider the GET request as shown. This will invoke the component’s search function, passing “your query” and “strict” as arguments.
This type of invocation is well-suited for Ajax-enabled applications. Access to a component’s documentation requires a password. These are especially useful for providing a familiar interface for web designers and content authors familiar with HTML but not imperative programming. The traditional and most common way is using CFML. A standard CFML page can be interpreted as a tag, with the tag name corresponding to the file name prefixed with “cf_”.

Attributes used within the tag are available in the ATTRIBUTES scope of the tag implementation page. CFX tags are prefixed with “cfx_”, for example “cfx_imap”. JSP tags are included in CFML pages using the CFIMPORT tag. NET by declaring them as web services. Recently, there has been much interest in Java development using alternate languages such as Jython, Groovy and JRuby. NET assembly without needing to recompile or alter the assemblies in any way.
NET without having to be installed on a Windows operating system. The original extension was DBM or DBML, which stood for Database Markup Language. However, it is becoming a less closed technology through the availability of competing products. Lucee – Free, open source CFML Engine forked from Railo. Lucee’s aim is to provide the functionality of CFML using less resources and giving better performance and to move CFML past its roots and into a modern and dynamic web programming platform. Lucee is backed by community supporters and members of the Lucee Association.

Railo – Free, Open Source CFML Engine. It comes in three main product editions, and other versions. The vulnerability had been identified and a patch released by Adobe for CF9 and CF10 in January. A security bulletin and hotfix for this had been issued by Adobe a week earlier. Massachusetts Rises Despite Passing of High-Tech Giants”.

Assignments, basic arithmetic and displaying things on the screen In every programming language there is a way to set a variable. For example, you can set variable “blah” to hold value of 123: . Variables can store results of adding numbers, concatenating strings or any other legal operation. I am sure that by now you have an idea, from the examples above, how one displays variable results to the screen.
The “variables” scope is the default scope. Take a look at the table underneath for a list of most common scopes and simple explanation as to their use. Discussion of less common scopes is beyond the scope of this tutorial. It is used to check whatever a variable exist. This function returns either “true” – variable is defined, or “false” – variable is not defined.
Default scope – when you create new variables without defining scope first, they are placed into the variables scope. Variables in this scope are created automatically on the page that is the target of a POST operation – see more infromation about forms later on in this tutorial. Variables in this scope are created automatically when the page you are on was invoked with the query string following the page address. Session variable support needs to be setup in the “Application. Variables set in the “variables” scope exist only on they page they were defined.
You create these variables yourself – they need to be enabled first in the Application. They exist for the duration of initialization of your application, by default for 2 days. They are shared among all users of your application, but not among different applications. They contain values such as end-user IP address.

Complex data objects: arrays, queries and structures Sometimes using simple variables holding just strings and numbers is not enough. At first you may think that you may get along without using structures, arrays and queries. However, just few simple real life examples will prove otherwise. I will explain using a simple example.
Say, you want to store person’s name, address, age, income and eye color on your page. You could define five separate variables, with simple data types. Instead of creating five simple variables – you should create just one, a structure. As you noticed from example above, you use the “dot” operator to define individual members of a structure. You may define as many as you like. Discussion of arrays is a continuation of the discussion about structures.
I will use continuation of the previous example to place array usage into a better focus. You will now see more clearly, why structures and arrays are so much better at data representation than just simple data types. As before, you could just create 10 separate variables. However, you are smarter than this – you will combine a structure storage of personal data with array storage. An array is a “list” of indexed “things”.

Above is a query with two rows, each containing 2 columns. Queries are special type of “structures of arrays” i. You can access information inside a query in the same way you would access information inside a structure of arrays. The example that follows shows you how to access data in the query provided above. Query is the format in which data is returned from the database.
Query contains in it besides data some special properties, for example, it contains the number of records it contains. For more information, look for tutorials on use of query of query. You should be aware that queries are not the only way to get data out of database, you may also use something called “stored procedures”. In this short section I will introduce you, very briefly, to the way you interact with a database. Before you can access all this data you need to connect to it. I assume, in the following example, that you have successfully setup datasource named “pubs” and a table with the name of “titles” exists in the database to which “pubs” point.
The letter “T” stands for “Transact” and “SQL” is a standard query language. Using form and URL variables to create forms I am sure you are already familiar with web forms. They are everywhere and are associated with dynamic web. Forms are created in HTML using special set of form building tags. Lets build a simple form and then a simple target page.
Note that I am going to use “post” method to send my form information to the target page. Post operation will create “form” scope variables on my target page. Almost in every case you want to use method “post” since it allows for much more data to be sent to the target page. However, “url” method is the default for historical reasons.
The “url” method will create “url” scoped variables, not “form” scoped. As you can see, we use “form” scoped variables on the target page as we would any other variables. Now, a quick introduction to a cousin of the “form” scope – “url” scope. One of the most important concepts in functional programming language group are the concepts of “if statement” and “loop statement”. Both of these are very fundamental and their syntax should be one of the first things programmers learn in new language. The “if statement” is a form of a question. If something is true then do this, if something is not true, do something else if defined, else proceed without doing anything.
Comparison operators are not case sensitive when comparing strings. Now its time for introduction of the “loop statement”. We start with a simple counter loop, where we count from 1 to 10. The purpose of loops is to repeat certain action for specific number of times.
Most common character used is a comma. For example, the following is a list of three elements delimited by a comma: “1,2,3”. Collection – loops over elements in a structure. In above function declaration, we see that all of function body is surrounded by cffunction tags. Inside above function you see that I have used “var” before the name of the variable. This means that these variables will only be accessed from within this particular function’s body.
They are private to this function. If you are returning something from your function then you need to use this tag. The whole discussion of object oriented programming is well beyond the scope of this tutorial. All I will do here is tell you how to create and access CFCs. They are stored in files with extension of “. For example, component names car will be stored in file named “car.
