Web Service Tutorial: Macromedia Tips

(Flash Professional Only)

In this tutorial, you use the Web Services panel to connect to a web service, which you use to

return a random tip about Macromedia software. You then use components to set up a simple

user interface.

In this tutorial, you will complete the following tasks:

•“Connect to a public web service” on page 5

•“Create a user interface and bind the components with the web service” on page 7

This tutorial uses a public web service and therefore requires that you have an Internet

connection.

If you have trouble downloading or decompressing the files, see TechNote 13686 at

www.macromedia.com/support/general/ts/documents/downfiles.htm.

Note: The use of a public web service in this tutorial in no way implies that you should use one for real-

world applications. In fact, Macromedia does not recommend using public web services directly from

within any client-side application. For more information, see “About data connectivity and security in

Flash Player” in the “Data Integration” chapter in Using Flash (in Flash, select Help > Using Flash). In a

production environment, you should use web services that are placed on your own web server.

The finished FLA file for this tutorial installs with Flash. The following list provides typical paths

to this directory.

•Windows: \Program Files\Macromedia\Flash MX 2004\Samples\HelpExamples\tips

•Macintosh: HD/Applications/Macromedia Flash MX 2004/Samples/HelpExamples/tips

Connect to a public web service

Define a web service in Flash that will connect to a public web service.

Create a new Flash document using Flash MX Professional 2004. Make sure your computer is

connected to the Internet.

Open the Web Services panel (Window > Development Panels > Web Services), and click the

Define Web Services button.

In the Define Web Services dialog box that appears, click the Add Web Service (+) button, then

click the highlighted line to edit it.

6 Web Service Tutorial: Macromedia Tips (Flash Professional Only)

Enter the URL http://www.flash-mx.com/mm/tips/tips.cfc?WSDL and click OK.

In the Web Services panel, inspect the methods, parameters, and results of the Macromedia Tips

web service.

The web service has one method, called getTipByProduct. This method accepts a single

parameter called product. The parameter is a string that tells the web service what

Macromedia product you want to see a tip for. In the next step, you bind this parameter with a

ComboBox instance in your application.

Right-click the getTipByProduct method, and select Add Method Call from the context

menu.

An instance of the WebServiceConnector component is added to the Stage.

Create a user interface and bind the components with the web service 7

In the Property inspector, enter the instance name tips_wsc.

The component is now configured and on the Stage. You can place the component anywhere

on or off the Stage—it is invisible when you run the application.

Create a user interface and bind the components with the web

service

Next, you use components to create a simple user interface that you can use to select a product,

click a button, and see a random tip about the product. You create this application by binding

the user interface components on the Stage to the parameter and results in the Macromedia Tips

web service.

In the Components panel, select UI components > ComboBox. Drag a ComboBox component

to the Stage. In the Property inspector, enter the instance name products_cb.

In the Components panel, select UI components > Button. Drag a Button component to the

Stage. In the Property inspector, enter the instance name submit_button and for the label

property type Get Tip, as follows:

In the Components panel, select UI Components > TextArea. Drag the component onto the

Stage. In the Property inspector, enter the instance name tip_ta.

In the Components panel, select UI Components > Label and drag a Label component onto the

Stage. Place it above the ComboBox component.

In the Property inspector, in the Instance name field type products_lbl and for the text property

type Select a Product, as follows:

The Property inspector showing the instance name products_lbl and the text Select a Product.

8 Web Service Tutorial: Macromedia Tips (Flash Professional Only)

Drag another Label component above the tip_ta TextArea component. In the Property

inspector, give it the Instance name tip_lbl and in the text field type Tips.

Now add a binding for the WebService connector component from the Macromedia Tip

service to ComboBox component that allows the user to choose a product and return a tip

about the product.

Select the WebServiceConnector component on the Stage. Open the Component inspector,

and click the Bindings tab. Click the Add Binding (+) button. In the Add Binding dialog box,

select product:String (under params:Object), and then click OK.

Create a user interface and bind the components with the web service 9

In the Component inspector, double-click the empty value in the Bound To field. In the Bound

To dialog box, select ComboBox, <products_cb> for the component path and value:String

for the schema location. Then click OK.

Bound To field in the Component inspector

Selecting the component path and schema location in the Bound To dialog box

Next, you will bind the results parameter in the web service connector to the TextArea

component on the Stage.

In the Component inspector, click the Add Binding (+) button again. In the Add Binding

dialog box, select results:String, then click OK. In the Component inspector, double-click

the empty value in the Bound To field, and in the Bound To dialog box, select TextArea,

<tip_ta> as the component path and text:String as the schema location. Then click OK.

Finally, you will use a Button component and the trigger() method to trigger the service.

You use the trigger method to attempt to retrieve a tip whenever you click the button.

10.

Open the Actions panel and add the following ActionScript on Frame 1 of the Timeline:

submit_button.onRelease = function(){

tips_wsc.trigger();

};

11.

Next, add the following ActionScript after the code from step 10. The code uses the

dataProvider property to set the items in the ComboBox instance to the contents of the array.

products_cb.dataProvider = ["Flash", "Dreamweaver"];

Note: If necessary, you can use the setStyle method to change the color of the Label instance

text to white using products_lbl.setStyle("color", 0xFFFFFF);

12.

Save your file.

13.

Test the application (Control > Test Movie). Select Flash from the ComboBox instance and

click the Get Tip button. The results should look similar to the following graphic:

Select Dreamweaver and click the Get Tip button again to view another tip.

XML Tutorial: Timesheet

(Flash Professional Only)

In this tutorial, you will create an application for editing timesheet data. The timesheet data is

stored as XML within a native XML database. The XUpdateResolver component is the best

choice for this type of application, because it generates XUpdate statements that can be sent to the

server to update the data.

You will complete the following tasks:

•“Create the user interface” on page 12

•“Edit the data” on page 16

This tutorial uses a public web service and therefore requires that you have an Internet

connection. In addition, the tutorial won’t work in a browser because of sandbox restrictions, but

will work in the Flash authoring environment or Flash Player.

Note: The use of a public web service in this tutorial does not imply that you should use one for real-

world applications. In fact, Macromedia does not recommend using public web services directly from

within any client-side application. For more information, see “About data connectivity and security in

Flash Player” in the “Data Integration” chapter in Using Flash (in Flash, select Help > Using Flash).

For this tutorial, you will need to download the Data Tutorials ZIP file from

www.macromedia.com/go/flmx2004_data_tutorials. The ZIP file contains the data.xml file you

use in the tutorial.

If you have trouble downloading or decompressing the files, see TechNote 13686 at

www.macromedia.com/support/general/ts/documents/downfiles.htm.

Note: For demonstration purposes, you will access the XML data from your hard disk and display

the DeltaPacket within your screen. In the real world, the XUpdate would be sent to the server

for processing.

12 XML Tutorial: Timesheet (Flash Professional Only)

Create the user interface

You will begin by creating a user interface, which displays the information in the XML file.

Create a new Flash document using Flash MX Professional 2004. Make sure your computer is

connected to the Internet.

From the Components panel, drag an XMLConnector component to the Stage. In the Property

inspector, enter the instance name timeInfo_con.

In the Component inspector or the Property inspector, click the Parameters tab. For the URL

parameter, enter data.xml, and for the Direction parameter, select Receive from the pop-up

menu.

From the Components panel, drag a DataSet component to the Stage. In the Property

inspector, enter the instance name timeInfo_ds.

On the Stage, select the XMLConnector component. In the Component inspector, click the

Schema tab. Select the results:XML property, then click the Import a Schema from a Sample

XML File button, at the upper right of the Schema tab.

Note: Alternatively, you can select Import XML Schema from the Component inspector title bar

menu.

Browse to where you saved the data.xml file, and select the file.

The Schema tab now shows the structure of the data in the file. The row node is mapped to an

ActionScript array of anonymous objects, because it repeats several times within the XML file.

Any subnodes or attributes directly under the row node are considered properties of the

anonymous objects contained within the array.

For more information about how Flash translates XML documents into an internal schema

representation, see the “Data Integration” chapter in Using Flash (in Flash, select Help >

Using Flash).

Create the user interface 13

Note: The XMLConnector component stores information internally as strings. When a request is

made for the data through a DataBinding component, you can define how the string data is

converted into the correct ActionScript types. This is accomplished by selecting an item within the

Schema Tree pane and modifying its settings.

Select the Date schema field. Its type is set to String. This is because the Flash authoring tool

cannot determine that it is a date type based on its value. You need to give it some additional

information to encode this value correctly.

Select the Data Type parameter for the Date schema field and change it to Date. This tells the

DataBinding component to try to work with this value as a date.

For more information on data binding and data types, see “Schema data types” in the “Data

binding” section of the “Data Integration” chapter in Using Flash (in Flash, select Help >

Using Flash).

Select the encoder parameter for the Date schema field and change it to Date. Select the encoder

options parameter and select the value “MM/DD/YYYY”. This tells the DataBinding

component how the string value is represented in the XML file. With this information, the

DataBinding component can successfully take any string in this format and convert it into an

ActionScript date object.

For more information on data binding and encoders, see “Schema encoders” in the “Data

binding” section of the “Data Integration” chapter in Using Flash (in Flash, select Help > Using

Flash).

14 XML Tutorial: Timesheet (Flash Professional Only)

10.

Select the @billable schema field.

Notice that the field’s data type was automatically set to Boolean by the authoring tool, which

looks for certain patterns to guess the type of an XML element. However, you need to modify

the Encoder Options for the field. For Boolean data types, the encoder options specify strings

that indicate true and false values.

11.

With the @billable schema field still selected, double-click the Encoder Options field.

12.

In the Boolean Encoder dialog that appears, enter true in the String That Mean True text box

and enter false in the Strings That Mean False text box.

13.

Select the @duration schema field.

Notice that the field’s data type was automatically set to Integer. This is because the sample

XML field contained only whole number values for this attribute.

14.

Select the Data Type setting for the @duration schema field and change it to Number so that

it is not limited to integer values.

15.

In the Component inspector, click the Bindings tab and create a binding between the row array

and the DataSet component’s dataProvider:Array property. Select the Direction property

and set it to Out.

The DataBinding component copies each object within the row array into a new record

(transfer object) within the DataSet component. It applies the settings you selected as the data

is copied, so that the DataSet component receives ActionScript Date, Boolean, and Number

fields for the @date, @billable and @duration attributes.

Next, you will create fields for the DataSet component that match those in the

XMLConnector component.

16.

On the Stage, select the DataSet component. In the Component inspector, click the Schema

tab.

17.

Click the Add a Component Property (+) button and enter id for Field Name and Integer for

Data Type.

18.

Using the same method, create the following new fields:

■Field Name = billable, Data Type = Boolean

■Field Name = date, Data Type = Date

■Field Name = duration, Data Type = Number

■Field Name = rate, Data Type = Number

Create the user interface 15

Note: The field names must exactly match the names of their corresponding properties within the

XMLConnector component (@date = date, @billable = billable, @duration = duration), including

capitalization.

19.

Select the Date field that you just created. Select the encoder setting and change it to

DateToNumber.

Note: The DataSet component needs to store date values in their numeric equivalents so that they

can be sorted correctly. This encoder converts a Date into a Number whenever the value is set. It

converts a Number into a Date whenever the value is accessed.

20.

With the Date field still selected, double-click the Formatter field in the Component Inspector

and choose Date from the pop-up menu.

21.

Double-click the Formatter Options field in the Component Inspector.

22.

In the Date Formatter Settings dialog that appears, enter MM-DD-YYYY in the Format

text box.

23.

Drag a DataGrid component to the Stage, and in the Property inspector enter the instance

name timeInfo_grd.

24.

In the Component inspector, click the Bindings tab. Create a binding between the DataGrid

component’s dataProvider property and the DataSet component’s dataProvider property.

Set the direction to In.

25.

Add another binding between the DataGrid component’s selectedIndex property and the

DataSet component’s selectedIndex property.

26.

Drag a Button component to the Stage, and give it the instance name loadData_btn in the

Property inspector.

27.

In the Component inspector, click the Parameters tab. In the Label field, type Load Data.

28.

With the button still selected on the Stage, open the Behaviors Panel (Window > Development

Panels > Behaviors).

29.

Click the Add Behavior (+) button, and select Data > Trigger Data Source. In the Trigger Data

Source dialog box, select the timeInfo_con component, and click OK.

30.

Save the file in the same folder where the data.xml file resides.

31.

Run the application, and click the Load Data button.

The XML data is retrieved, converted, and loaded into the DataSet component. The binding

between the DataSet and the DataGrid copies the data into the Grid for display.

16 XML Tutorial: Timesheet (Flash Professional Only)

Edit the data

Now you will modify the application so that you can edit data through the DataGrid component.

On the Stage, select the DataGrid component. Then click the Parameters tab in the

Component inspector.

Set the editable property to true.

Run the application.

You can now edit the data within the grid.

XUpdate Tutorial: Update the Timesheet

(Flash Professional Only)

Prerequisite: “XML Tutorial: Timesheet (Flash Professional Only)”

This tutorial starts where the XML tutorial: Timesheet left off. Now that the DataSet component

is managing the Data, it is tracking changes that are made to the data into the DeltaPacket. A

resolver is needed to send the changes back to the server in an optimized way. The

XUpdateResolver component is the best choice for updating an XML source, because it generates

XUpdate statements that can be sent to the server to update the data.

You will complete the following task:

•“Update the timesheet” on page 18
