Flex :: Custom Sorting Capabilities With Server Side Support?
Feb 22, 2010
The sorting capabilities that are available in Flex assume that you have access to all the data, but I'm using a paginated datagrid (with custom code), the datagrid is binded to an ArrayCollection instance, on the next page call I change the data of the dataprovider and everything works ok, but for sorting I need to override the click or event better override the sort method of the arraycollection
All this is to be able to do a server-side sorting.
We are building a Flash application for client use but will need to do server side processing of images. All our expertise and application code is in Java, but I've been told Dot Net has better Flash support. This is general but we will be modifying large (up to 50MB) image files. The idea is that what we could do in Flash should be duplicated, automated and extended on the server side.
I want to download files from the server side to client side without prompting a window to the user to download when any updates happen at server side.Right now I am using urlstream class but first file is downloading completely rest of the files contents downloading partially.
editCode sample taken from other post. Warning: it's a huuuge chunk o'code.
Is there any way to make a flash object where users can interact but has no server side support. All users are in the same network, the swf file would be on a shared drive. Nothing complicated, just one frame where everyone (about 10 user) can make modification. No login, no password.
I'm wondering if anyone might be able to give me a general overview on the state of implementing 3d in flash. More specifically, realtime 3D rendering on the fly, for something like making a game engine.not that i'm planning to start work on any projects on the subject just now, but i'd like to know if it's worth considering some 3D work in futurethus far i've only seen two games which use 3D in flash:This one is a strange car driving game. Three things strike me right away:1. The player's car is just a wireframe, and has a very simple mesh2. All the level components are just planed, with a few exceptions3. Most of the ground parts share the same texture.
Maybe i'm reading too much into it, but to me these things suggest some pretty heavy resource limitations.The other one is: htthis is an fps, of sorts. Again some things stick out glaringly, and i'm not certain whether they're design choices or working around limitations:1. Generally low poly models, things look blocky2. low res textures too3.Fixed camera angle.it reminds me of the sort of graphical quality we had when 3D was first being introduced to mainstream PC gaming. Are these games a good representation of the kind of 3D rendering flash can currently handle? Is it possible to make things much more detailed, that can run smoothly on average hardware?
I want to create an application that has these features
- At client side: Display a list of images, when user click on one image, data will be stored in MySQL database.
- At server side: Manage images used in client side, I can delete, add new images.
Is this possible for me to achieve this using Flex? And if it is able, will my output be 2 separate SWF files? And where can I find the materials to read on writing such applications?
User interacts with Adobe flex webpage to configure reports based on some data stored server side. They configure their view and have THAT view emailed to them daily. I've got the report builder, the part I'm trying to figure out is how to render the report server side and send it out as email (native flex functionality? convert to html? take screenshot? assume something is running client side?...)
I am writing a thesis and have been able to place all my frameworks under two categories (client-side frameworks and server-side frameworks), but I can't seem to finf where to place Adobe Flex...In which category should I place this or should I place it in some separate catgeory?
I extended the DataGridColumn because I wanted to include a custom itemToLabel function (to be able to show nested data in the DataGrid. See this question.
Anyways, it also needs a custom sorting function. So I have written the sorting function like so:
private function mySortCompareFunction(obj1:Object, obj2:Object):int{ var currentData1:Object = obj1; var currentData2:Object = obj2;
[Code].....
Whenever I try to sort the column, I get the error "Error: Find criteria must contain at least one sort field value."
When I debug and step through each step, I see that the first few times, the function is being called correctly, but towards the end, this error occurs.
Now, to sort them, I obviously don't want to do something like this:
if( a == 'columnSelector' && b == 'headerImageLink' ) return -1; else if( a == 'columnSelector' && b == 'title' ) return -1; else if( a == 'columnSelector' && b == 'mainText' ) return -1;
So that brings up an interesting thing. I know you can optimize the above some using something like this:
if( a == 'columnSelector' || a == 'bodyImage' ) return -1;
This would get the last two, but lately I have just wanted community input on issues I have had in the past. So the question is, what is the best way to write a custom sort, using a relatively random order (not alphabetical, etc)?
Below is the code. When the swf is connected to FMS(the connection is successful) I use this application.user_so.send("enterContestGroup"); to call the client side mothed. You can see that in the client side I have defined the "enterContestGroup" mothed. However the fact is it doesn't call that mothed. Can anybody tell me what the error is
Since I'm developing a multiplayer card game for Facebook using Flex as client side and Java SE as server side, I wanted to know how do I actually make the connection between Flex and Java? the server and client should be able to send each other data(cards,movement,room information etc...) across and I wonder what's the easiest way to do it without complicating it. where to read about it ? I know JAVA but I find JavaEE hard to understand.
I'm trying to create a client-side web app that generates music procedurally using some user-input parameters, so I'm looking for a framework (e.g. Flash, Silverlight etc.) that has the capability to play audio at a specified pitch. Whether it is playing a WAV/MP3 file, using MIDI output, or just playing beeps doesn't really matter -- I just need something that will enable me to generate arbitrary music client-side.
I've done a bit of searching and it appears that Flash might have the ability to change pitch with the help of a third-part plugin, but I couldn't find anything similar for Silverlight.
I know flex is a client side technology, but our customers are asking us to e-mail them reports (i.e. graphic images) that look just like the flex graphics we show them on the desktop on a nightly basis.
I've got Flex 4, Zend and php. I've set up paging in my datagrid but how do I do server-side filtering? I have about millions of records so obviously can't do client side filtering.
I wonder if it is possible to pre-configurate Flex Elements on the Server. I have the Problem with a custom ItemRenderer which turns out to be very slow. It would be very cool to pre-process such an element on the server instead in the clients browser... somehow? Maybe it is possible to produce the MXML dynamically on the server for that.
This is it basically. I create a Label for each data entry in an array list. This entry is added to a BorderContainer and this goes to the containing element as a whole here. Sometimes i add 200 - 300 items this way which is costing very high computing cost at client side. So i wonderd if i could just pass this as a whole dynamic mxml element to the client.[code]...
I am making an app where people upload a bunch of images and it thumbnails them and saves them to the server. Is it better to create thumbnails from the uploaded images, or to upload them to the server then re-download the thumbnails?
We're looking for a good server to purchase to develop games with Flash/Android/iPhone clients with a .NET backend server (And even more importantly, that supports clustering and scaling in general).Now we've examined both ElectroServer and SmartFoxServer (both products look fine and suitable for our needs), however both can only be extended using Java.
I am new to web technologies. I along with my friends want to develop a web application. There is one guy in our team who knows Flex technology. I would like to use Java Springs framework at the back end. The web application caters to students a Music school. And for the same reason we chose Flex for UI since the application needs to be flashy and rich in graphics.
The application allows students to create profiles and interact with the teacher. Eventually we want to add Online Music classes feature with online payment gateway integrated. Kindly guide me which are the suitable technologies to use at the back end. Also let me know if SpringFlex with BlazeDS integration is a good combination with Adobe Flex.
Just to confirm what I think I understand from reading about use of google APIs in RIAs (FLEX 4 and ActionScript) there is no way to connect to blogger API for example, directly from RIA because of google's crossdomain.xml file, right?
So if I want to use their APIs to get some data like content of my mailbox or list of posts on my blog I have to have some code running server side and RIA would just use that code as httpservice to collect data from google?
Using RecursiveDirectoryIterator of PHP i am able to create directory tree and can even flatten it using RecursiveIteratorIterator class , but I want to create directory tree structure which TREE component of flex understands . The following is an array structure in php which flex understands.
One of my web applications have developed in java and using tomcat server. Now I want add one more feature in my application that is peer to peer audio streaming. Actually I want that anyone speak (using microphone) on the client side and I will hear his voice on my server speakers and vice versa. Also save our communication in any file and also send the audio stream to IP intercom.
For that I am trying to use Flex Builder. Flex NetStream class is good for the streaming and we can also attached microphone. But the problem is on the server side. How can I get the audio stream on server side?
how can I get stream from server to client and vice versa?
I am using AIR with tomcat..(blaze ds as bridge) but i changed in service.config also in server side but i got the following error.. how to rectify this problem Result : [RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 404: url:
Flex: - Is it possible to export Chart/Graph/component with dataGrid data into xls file without using server side?
(Web Application)
I have gone through number of article but could not find any hind to do. As per few article it is possible to export data of dataGrid into xls by using as3xls-1.0.swc but not Chart.
I am looking to export data from dataGrid as well as Chart.
I have a java class which has been deployed as WAR web application in a BlazeDS/Spring server sitting on JBOSS. Apart from the Flex application which will access the WAR file, I also need to start some server side process's which will initiate BlazeDS "pushes" to the Flex client via AMF messaging.
What is the best way to implement this server side process? - Should it just be a class with a main() method in the WAR file which gets called from the command line? Can this be done - not sure you can run a class in a WAR file from command line? - Should it just be a class with a main() method in a JAR file which gets called from the command line? Not sure what the standard practise here is. The key is that the process needs to be started on the BlazeDS server to push data out (not on the Flex client).
We are trying to create a sqlite db file using java on the server, and encrypt it.Then we send the encrypted db file to a client's pc, which has an Adobe Air desktop app running.The air app then needs to be able to open/read-from the encrypted db file (client is read-only).We are using java 1.6, flex/actionscript 4.5, and Air 3.1.We can create the sqlite db file on the server and send it to the client, and it can be read by the client without issues, when we do not encrypt it.But we are having trouble with the encryption part. We've read quite a lot of documentation about Actionscript's ability to open encrypted sqlite files using AES + CCM (URL...).And we're trying to use java's crypto package to encrypt the sqlite db file.The encryption is important because we don't want the client to be able to open the sqlite db file with any sqlite browser, only with our Air application.
I got a mxml file that launch a script on my http server through a HTTPService.send() call. Since the script on the server side takes a LOOOONG time (it could take even more than a hour) i would like to drop the connection between my air application and server when a button is clicked. Don't know why but calling HTTPService.disconnect() is totally useless... No tcp connection drops and script keeps on running on server side. No HTTPService.cancel() nor set HTTPService var to null worked.
I am trying to sort big array using actionscript 3. The problem is that i have to use custom sorting function which is painfully slow and leads to flash plugin crash.
Below is a sample code for custom function used to sort array by length of its members:
I'm doing a project where I manually create sorting algorithms.After several tests I found out that my heapsort is way quicker than quicksort (I think it should be the other way around), my selection sort is also faster than insertion sort.I'm testing using integers from -100 to 100, randomly generated, 5000 values in an array (I modified this number several times, still the same problems).My quicksort isn't in-place.I thought that maybe flash's recursive functions are slow? my heapsort uses loops, unlike quicksort. That's just a hypothesis though. I start a timer, run the class's exec() function, stop the timer and calculate the elapsed time.[code]
