This is a technical portal site for all Macromedia products designed by our experts. The content will be dominated by ColdFusion and be integrated with flash as the front-end, discussing all the MM products and introducing the latest news, inspiring more extraordinary online applications, no matter what happens to Adobe's integration with mm in the future, the intention of this promotion will never change, because it can bring you up your interest in

Width = "Verification Code image width" Height = "Verification Code Image Height"TEXT = "Verification Code text" fonts = "Verification Code font"Difficulty = "difficulty">Note:
1. ColdFusion automatically adds a random background and automatically skews text.2. difficulty can have three values: low, high, and medium. Different levels of difficulty indicate the complexity of the verification code image!Example:
the customer segment page, you can use variables or objects of complex structure types (at the same time, the object must implement the serializable interface, after all, it must be serialized to the text ), but it will increase the size of the final HTML page and increase the data traffic, which can be ignored in the broadband environment.
6. Request domain variables:
Store the data to be transferred in the httpcontext structure for subsequent use by multiple requests. This is useful when
This tutorial is divided into two parts: 1 Create a CF component 2 create a Flash application. Create a new site before you start. Creating a CF Component: Here we create a component that defines two functions [chaxun1,chaxun2], functions that use EXAMPLEAPPS database sources, Returns a query result object in which the Flash movie file invokes the component method and receives the returned query results. The CHAXUN1 function requires three parameters, which are passed from the Flash movie. (para
First put the Java class called into a jar package into the ColdFusion installation directory D:\ColdFusion9\lib.
Here is the call page:
Objfile=createobject ("Java", "java.io.File");Objfileinstream=createobject ("Java", "Java.io.FileInputStream");Objioutils=createobject ("Java", "org.apache.commons.io.IOUtils");Objftpclient=createobject ("Java", "org.apache.commons.net.ftp.FTPClient");
Recently in doing a ColdFusion project, the development of the program all normal, but when deployed to the server, and then run the original program, the page will appear in Chinese garbled? Even more strangely, the fixed text written on the page is garbled, and the query from the database is normal.Method One: In order to Project no trouble, temporarily use a very stupid method to solve, namely in the page Method Two: But this is definitely not the
Builder Mode
The builder model can separate the internal appearance of a product from the product generation process, so that a building process can generate product objects with different internal appearances.
Object Construction
In some cases, an object has some important properties and cannot be used as a complete product until they have no proper values. For example, an email contains the send

And everyone at each stage is certainly not the same ah, I think it can be said that there are no two people in the world in this 5 stages of life is exactly the same, but people who live to 70 years of age, have experienced these stages is certain. In fact, this is an example of a more classic

1: Intention: separates the construction of a complex object from its representation, so that different representations can be created during the same construction process.

Builder mode Definition: separates the construction of a complex object from its representation so that the same build process can create different representations.The builder pattern is a step-by-step creation of a complex object that allows the user to build them only by specifying the type and content of the complex objects. The user is not aware of the specifics of the build internals. The

Introduction:For Android, the Builder design mode may be rarely used in our development, but we may have seen that AlterDialog. Builder is a Builder mode. So what is the builder model? Let's take a look at its
Builder mode is the creation mode, creating a product that hides the creation process, using a combination of methods, by the conductor (director) to determine the construction processpublic interface Builder {void Buildparta (); void Buildpartb (); void Buildpartc ();}public class Builderimpl implements Builder {@Overridepublic void Buildparta () {System.out.pri
The builder pattern is somewhat similar to the previous abstract factory pattern, but more powerful than the abstract factory pattern, the builder pattern can be seen as two parts, one builder, and the other is that the basic idea of Director,builder is the abstract factory, While the director exists to make the use of
Idea: Since the interstellar picture is made up of several parts: the map (the terrain and the minerals), the building, the troops. Then we think of them as parts, assembled to be the final product (the whole picture).

The code is as follows

Because a complex object has many components, such as a car, a wheel, a steering wheel, an engine, and various small parts, how can we assemble these components into a car, this assembly process is long and complex. In this case, in order to hide implementation details from the outside during the construction process, you can use the

Separating the construction of a complex object from its representation allows the same build process to create different representations.
