Sample Applications 41

To write the server-side ActionScript for this sample:

1 Create a new file using your server-side ActionScript editor, and write an event handler for

when the user connects. In it, you’ll receive the name passed in by the client, accept the client

connection, create a message that uses the client’s name, and call the client

msgFromSrvr

function to return the message.

application.onConnect = function(newClient, name) {

// Give this new client the same name as the user name

newClient.name=name;

// Accept the new client’s connection

application.acceptConnection(newClient);

// Create a customized "Hello [client]" message

// that the server will send to the client

var msg = "Hello! You are connected as: " + newClient.name;

// Print out status message in the application console

trace("Sending this message: " + msg);

// Call the client function, message, and pass it the msg

newClient.call("msgFromSrvr", false, msg);

}

Save the file as main.asc in a doc_hello directory under the flashcom applications directory.

Note: Save this main.asc file where you’ve chosen to store your server-side application files. For example, if you

chose Developer Install during installation, save this file to the same directory where you’ve stored the client-side

SWF file and its source FLA file. If you chose Production Install and you have a Web server, the Flash

Communication Server will look for your client-side files under \flashcom\applications in your Web server's root

directory and will look for your server-side application files (including this main.asc file) under \applications in the

directory you specified during installation. The <AppsDir> tag in the Vhost.xml server configuration file contains

the location of your flashcom application directory. For more information see Chapter 1, “The flashcom

application directory,” on page 15.

To test your sample application:

1 In the Flash MX authoring environment, after you have saved your work, publish it by

selecting File > Publish.

2 Open the SWF file in the application directory.

3 Overwrite the text in the login box by typing your name, then click Connect. You’ll see a

message like this one:

Hello! You are connected as: [your name]

Sample 5: Text Chat

In the Shared Text example (see “Sample 2: Shared Text” on page 35), you created a remote

shared object that enabled a user to view another user’s typing in real time, letter by letter. In this

next sample, you’ll create a different kind of shared object that sends whole messages on

command. You’ll also add several elements to make the text chat application more versatile,

including fields for logging in, typing in a chat room name, and viewing the list of current

participants.
