Hi Flep,
My first time contacting you. I must tell you, your work with utilities has been instrumental in taking me from novice to intermediate. So a big thank you!
I have added some more features to the ImagesScoller, however I can't figure out a way to make the name of the XML file dynamic and how to link what XML file gets pulled to a combobox. Here is the link...
main
Long term, the combobox will be populated from an SQL database. And XML files, will be added with a certain naming convention created via a PHP script, which will also link SQL database names with XML file names and locations.
The only code I have changed is in Main.as. My thought was I was going to have LoadingXML.as dynamically pull from a .txt file. And everytime a new "Item" was "selected" in the comboBox, flash would write URLvairables to that txt file, and then when LoadingXML was forced to UPDATE it would pull the myComboBox.selectedItem name , now stored in the txt file, and change what XML file it is opening.
I have tried this in a couple different ways, I can see that the problem lies in REFRESHING the Arrays, if I knew how to load "LoadingXML.as" fresh everytime a comboBox Item was selected, I would be done. But I don't know how to removeChild so to speak the Arrays and finally how to call back up "loadImages()" and have it load LoadingXML fresh everytime. Where in LoadingXML I would place...
Code:
//Create the URLLOader instance
var myLoader:URLLoader = new URLLoader()
//the data will come as URL-encoded variables
myLoader.dataFormat = URLLoaderDataFormat.VARIABLES
//Load using an URLRequest, even beeing local
myLoader.load(new URLRequest("refXML.txt"))
//onLoad handler listener
myLoader.addEventListener(Event.COMPLETE, onDataLoad)
//Error handling
myLoader.addEventListener(IOErrorEvent.IO_ERROR, onIOError)
myLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecurityError)
//Could be an error or just a message
myLoader.addEventListener(HTTPStatusEvent.HTTP_STATUS, onHTTPStatus)
//add a listener for the complete event
function onDataLoad(evt:Event){
Title_txt.htmlText = evt.target.data.Title
}
//error callbacks
function onIOError(evt:IOErrorEvent){
trace("IOError: "+evt.text)
}
function onHTTPStatus(evt:HTTPStatusEvent){
trace("HTTPStatus: "+evt.status)
}
function onSecurityError(evt:SecurityErrorEvent){
trace("SecurityError: "+evt.text)
}
stop()
and do something like this to your LoadingXML.as code
Code:
private function loadXML():void
{
var loader:URLLoader=new URLLoader();
loader.addEventListener(Event.COMPLETE,completeHandler);
// Cambia l'url del file XML
var request:URLRequest=new URLRequest(evt.target.data.Title + ".xml");
try
etc..., etc...
Finally, here is the modified Main.as
Code:
