Using Flash Remoting with ColdFusion pages 103

The directory name is the service address, and the helloWorld.cfm file is a method of the

helloExamples directory of the Flash Remoting service. The following ActionScript example calls

the helloWorld ColdFusion page:

import mx.remoting.Service;

import mx.remoting.PendingCall;

import mx.rpc.RelayResponder;

import mx.rpc.FaultEvent;

import mx.rpc.ResultEvent;

var CFMService:Service = new Service(

"http://localhost:8300/flashservices/gateway",

null,

"helloExamples",

null,

null);

var pc:PendingCall = CFMService.helloWorld();

pc.responder = new RelayResponder(this, "helloWorld_Result",

"helloWorld_Fault");

function helloWorld_Result( re:ResultEvent ):Void {

trace( re.result.HELLOMESSAGE ); // will output "Hello World"

trace( re.result.TIMEVAR ); // will output current date

}

function helloWorld_Fault( fe:FaultEvent ):Void {

}

Within the result handler of the helloWorld() method, you access the structure returned by

ColdFusion.

Returning record sets to Flash

A Flash application often calls a ColdFusion page so that the ColdFusion page can access a

database and return a record set to the Flash application. For example, the following ColdFusion

code executes a query and returns the results of the entire query to the Flash application:

SELECT *

FROM tblItems

</cfquery>

You can pass parameters from the Flash application to the ColdFusion page to conditionalize the

query. The previous section contained an example that passed a parameter to the

WHERE clause of

the query, as the following code shows:

SELECT ItemName, ItemDescription, ItemCost

FROM tblItems

WHERE ItemName='#Flash.Params[1]#'

</cfquery>
