3 In the same method, assign a variable name, recstr, for the data coming from the call to

getRecordString and populate the list box with the data.

for (var i in this.data) {

if (i == "__COLUMNS__")

continue;

var recstr = getRecordString(this.data[i], this.data.__COLUMNS__);

records_list.addItem(recstr, i);

}

records_list.sortItemsBy("data", "ASC");

}

Connect to the shared object.

recset_so.connect(nc);

Create the getColumnString function to get all the column data.

// Get a string out of all column headers

function getColumnString(cols) {

var colstr = "";

if (cols.length > 0)

colstr += cols[0];

for (var i = 1; i < cols.length; i++)

colstr += ", " + cols[i];

return colstr;

}

Create the getRecordString function.

// Get a string containing all records in column order

function getRecordString(inx, recs, cols) {

var recstr = "";

if (cols.length > 0)

recstr += recs[cols[0]];

for (var i = 1; i < cols.length; i++)

recstr += ", " + recs[cols[i]];

return recstr;

}

Create the event handler for the GetRecs_btn button. When the user clicks the button, the

doGetRecords method is called; this function contains the getRecords call defined in the

server-side ActionScript.

// Call the server to initiate a database query and place

// the recordset data in ’records’ shared object

function doGetRecords() {

nc.call("getRecords", null);

}

To write the server-side ActionScript for this sample:

1 Create a new file using your server-side ActionScript editor, and load the netservices.asc file to

enable Flash Remoting through the Flash Communication Server.

load("netservices.asc");

Get the records shared object.

gRecords = SharedObject.get("records", false);

// Set the default gateway URL

NetServices.setDefaultGatewayUrl("http://localhost:8500/flashservices/

gateway");
