[flexcoders] Flex performance problem, pure MVC, AIR
I made Image Browser application. User can select any number of images and browse them in application. I use Flex SDK 3.4 AIR framework Pure MVC Framework Main screen contains big container for images and one container that preview same images just smaller (thumbnails). For thumbs I used TileList controll with Simple Image item renderer. Each image is represented like PImage class value object that contains image ID and path. When user select images that want to browse all images (PImage) are stored in ArrayCollection. Problem: When I select big number of images 50...200 or more and scroll in thumbnail container left-right I feel bad performance. User want to have smooth scroll but it's slow. I turned on live scroll on that container but still it's slow. Is there any other way to solve this performance issue? PS Images must be storred in that ArrayCollection.
[flexcoders] Fluorine fx, enterprise library, flex problem
Hi all, I have one problem, I used enterprise library Data Access Application block for my .net project (GUI was built in windows forms) and app.config was stored in GUI project. Now I switched from main windows form project to fluorineFx site project and I can't access my database anymore. I don't know anymore how to locate this app.config and I don't know what to put in web.config because I think that now old app.config data should be in new FluorineFX web.config. And now I cant point my .net code from flex :( Thanks

[flexcoders] AIR with database advice
Hi, I want to make desktop AIR application. This application must have access to its database which is made in MS SQL Server. Now I have created .NET application (Web Service) that access this database. And initial thought was to host this service somewhere but problem is that my clients want to have their databases on their computers and that computers will not be connected to the internet. Now I don't know what to do. 1) To use other technology? 2) To use SQLite - I have never work with this, I don't know is data security, can I daily make database backup etc. 3) Any other suggestion? Thanks
[flexcoders] How to bind a ProgressBar to an XML file loading process
I have an XML file loaded like:
private function studentServiceResultHandler(event:ResultEvent):void
{
var students:ArrayCollection = event.result.catalog.student;
var temp:ArrayCollection = new ArrayCollection();
var cursor:IViewCursor = students.createCursor();
while (!cursor.afterLast)
{
var student:Student = new Student();
student.fill(cursor.current);
temp.addItem(student);
cursor.moveNext();
}
catalog = temp;
}
I can't figure out how to put the ProgressBar that will fill as the array
gets loaded with data from the XML.
Please help!!!
Thx in advance,

[flexcoders] DataGrid - Swap columns and rows
Hello everybody! I have an XML file containing data of only one student sth like: Vlada Stankovic 24.09.1984. 5+ FON . . . I would like to show data in the grid view but instead of columns I would like rows to take the names of the student tags and to have 2 columns (one with tags and the other with data). How can I do this in flex? Thx in advance!

When I run my application, It seems that a lot of requests are done to the Web Service repeatably requesting the same XSD's (complex types). It looks like the application is in an infinite loop, constantly doing the same requests.. No call the the web service is made yet at this point. If I call the requested XSD manually in my browser, it is resolved without problems. And if I call another very simple web service, everything is working as expected.

[flexcoders] Re: Setting combobox selectedindex
I'm a little bit lost in those replays :)
Next example will do next:
When array collecting which is data provider changes, selected index
will set to initial (for example second item - 1).
On page creationComplete, add event listener
method implementation is following:
private function init():void
{
//Every time selectedProduct.typeNames changes method
WatcherListener will be called
ChangeWatcher.watch(this.selectedProduct, "typeNames",
WatcherListener);
}
public function WatcherListener(event:Event):void
{
productSubTypeCB.selectedIndex = 1;
}
