Good morning all.
I'm having trouble with a file download component I've written. It worked fine
debugging, but when testing an installed version of the application, there
seems to be a problem with the loop, and files not completely downloading.

I have tested, and one file in the loop is writing to the directory
(event.complete action) at about 45%.
How can I check if the total bytes downloaded is the same as total available,
and if not, force it to carry on the download for that particular item?

The code for the page is below:

public function Update():void {
if(appModel.fileArrCol.length > 0) {
var urlReq:URLRequest = new
URLRequest(appModel.fileArrCol[0][1].toString());
trace(urlReq.url);
urlStream = new URLStream();
urlStream.addEventListener(IOErrorEvent.IO_ERROR, onStreamError);
urlStream.addEventListener(ProgressEvent.PROGRESS, progressHandler);
urlStream.addEventListener(Event.COMPLETE, fileTransferHandler);
urlStream.load(urlReq);
}

}

private function fileTransferHandler(event:Event):void {
urlStream.readBytes(fileData, 0, urlStream.bytesAvailable);
var fileLoc:String = appModel.fileArrCol[0][2].toString() +
appModel.fileArrCol[0][0].toString();
var file:File = File.applicationStorageDirectory.resolvePath(fileL oc);
var fileStream:FileStream = new FileStream();
fileStream.addEventListener(Event.CLOSE, fileClosed);
fileStream.addEventListener(IOErrorEvent.IO_ERROR, onStreamError);
fileStream.openAsync(file, FileMode.WRITE);
fileStream.writeBytes(fileData, 0, fileData.length);
fileStream.close();
trace("File " + appModel.fileArrCol.length + ": " +
appModel.fileArrCol[0][0].toString());
}

private function onStreamError(event:IOErrorEvent):void{
//Alert.show("Invalid Username or Password!","Warning");
this.showCloseButton =true;
btnUpdate.visible = true;
trace(event.text);
}


private function progressHandler(event:ProgressEvent):void {
/* bar.setProgress( Number(event.bytesLoaded / event.bytesTotal), 1 );
*/
bar.setProgress(event.bytesLoaded,event.bytesTotal );
progLabel.text = "Downloading " + Math.round(event.bytesLoaded / 1024)
+ " kb of " + Math.round(event.bytesTotal / 1024) + " kb " +
(appModel.fileArr.length - 1) + " files remaining";
}


private function fileClosed(event:Event):void {
// run a progress bar or sqlite table update here
appModel.fileArrCol.removeItemAt(0);

if (appModel.fileArrCol.length > 0){
Update();
} else {
progLabel.text = "Uploads Complete";

var thisServerVersion:String = appModel.fileDownloadServerVersion;
var thisDescription:String = appModel.fileDownloadDescription;
var thisDownloadDate:String = appModel.fileDownloadDate;

// store the file download details within the database table
if(appModel.checkFileDownloadHistory(thisServerVer sion).valueOf() > 0) {
// a record matches the version number in the xml. do nothing
} else {

appModel.storeFileDownloadHistory(thisServerVersio n,thisDescription,thisDow
nloadDate);
}
// close the box down
PopUpManager.removePopUp(this)
}
}

public function init():void{
btnUpdate.visible = false;
this.showCloseButton = true;

if (appModel.urlAvailable){
Update();
}else{
Alert.show("No Network Connection Detected","Message");
this.showCloseButton =true;
btnUpdate.visible = true;
}
}


public function titleWindow_close(evt:CloseEvent):void {
PopUpManager.removePopUp(this)
}

The application reads the number of files from an xml file on the server. That
works fine, but I think the loop is wrong. In debug, it traces the file names
without a problem

Please please please can someone help me? I need to get this sorted and
resolved by this lunchtime.

Many thanks in advance,

Matt
