Php :: Flex - Retrieving Base64 Encoded Image From Database?
Mar 23, 2011
I'm developing a flex application that displays a list of images along with some metadataThe images are less than 500kb. They are stored in the database as base64 encoded stringsretrieved using PHP, send over to flex as XML (which creates a fairly large XML output file)Now my problem is that, while I can display upto 2-3 images easily, anything more than 3 or sometimes 2 images will cause the images to be corrupt. Sometimes the whole app fails.I am guessing this is due to the large size of the generated XML. I know I am doing something wrong here. I want to know what is the proper method for storing/retrieving a lot of images in a flex application.

I have a string of of base64-encoded PNG image that is suitable to use as a src (source) attribute in a <img> tag. However I need to transfer this image to Flash applet where I need to create (show) the image fast. Is there a way to simply use the data string and somehow create an image (inside a Flash movie) from it?

I have recently been using Charles the debugging app. And noticed a very chatty app named skyrocket (a very very cool slide presentation app) sending a lot of data across the wire. It is built in flex by the looks and I was wondering why they had chosen to send their data using base64 and not amf. Is it because they don't want to be locked into the flash platform? Or could there be another reason. Is it to store it as XML in the database as they don't want to be dealing with amf when handing data to other services/clients (iPhone etc).

I have this little piece of code to retrieve data from a local SQLite database (to an AIR app):
import flash.filesystem.File;
import flash.data.SQLConnection;
import flash.data.SQLStatement;
[Code]....
It is only a "proof of concept" piece of code and it "lives" in the first frame of the timeline of the Flash IDE. What happens? When I compile my SWF (AIR for iPhone), I get this error:
SQLError: 'Error #3115: SQL Error.', details:'no such table: 'background'', operation:'execute', detailID:'2013'
I created a basic db with a Firefox extension (SQLiteManager). What can cause this error? The table exists!

How do i save an array of objects, like this: [{n:1,bb:4},{n:2,bb:4,r:1},{n:6,bb:7},...] to a database? I was thinking i would have to convert it to string, but if i do that, when i retrieve it from the database, how am i going to use it?
EDIT: forgot to mention that the objects can contain an array of objects as well, but there won't be any more arrays beyond that point.
[{n:1,bb:4},{n:2,bb:4,r:1},{n:6,bb:7},{arr:[{a:11,b:2},{a:11,b:2},...],r:1},...]

In Flex, I have a GUID that I receive as input in the following format "as a string. How would I convert this to a string of Base64 encoded values?
Please note that we have to account for leading zeroes in each section of the GUID, for example, "0091AFBC-8558-482A-9CF6-64F1745E7AC1"

In javascript, I have a variable which holds a pdf in base64 (the pdf is generated in flex and passed to js). I want to open it in the browser (ie I want the browser to display the open/save dialog box letting the user open or save the pdf).
I am using Data URI which works fine in some browsers, but is not supported in IE 6/7:
function getPdf(pdf) {
window.open("data:application/pdf;base64," +pdf);
}
How can I get this PDF to open in IE6 and 7? I've read about MHTML as an alternative to data uri but I don't think it can do what I need, or can it? For now I just need to open pdfs but in the future I will probably need to add support for xls (MS Excel) files too. Currently I'm using Flash's Filereference.save to let the user save the pdf to the disk then he can open it, but the client is insisting on giving the user a choice to open it automatically rather than forcing him to save it first.

Flash will be receiving a Base-64 encoded image (from a web service) and need to convert & display that image on the stage.
For conceptual purposes, I'm omitting the web-service aspect for now and just reading in a Base-64 string, generated from an online service.
Now that I have the data into Flash, how do I properly convert it to an image and display it.

So basically, I need to find a way to retrieve the image url that is stored in a database, and I need to do it through asp.net if possible (I want to avoid XML if I can). I'm an actionscript 3 newbie so I don't know what calls I might use to connect to the .net page, but I am able to retrieve the data through SQL to the .net page.

I want to create a Flex 3 application running in Adobe Air that accesses an SQLite database and I need to keep this database in sync with an SQL server 2005 database running a website.Is this something that Flex supports or is it going to be a custom script? Also, has anybody done anything like this?
Edit: The synchronisation can be done on a daily basis rather than real time. The data will be read only from a front end perspective with a CMS to do updates on the website.

I have researched this issue all over and most people say use the .refresh() method to update a datagrid after updating or adding a new record. This does not do anything. So, my issue is this. I have a mySQL database hosted I am connecting via PHP, I have 1 mxml file and 2 php files (I know I can use just 1 but I am learning and this was easier for me to use for troubleshooting). The issue is no matter what I change on the datagrid the update does not show on the datagrid unless I close out of IE and reopen it. I can refresh or open the page in another window and the update does not show. I have to exit entirely and restart in order for any updates or additions to show.Here is my licenseTracker.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

I am planning on using Flash Builder 4/Flex to write an AIR application which is primarily based around recording, storing and analyzing data.I'll be creating charts etc that need to update in almost real time.It's essential to me that the application be able to function without an internet connection so I need a local database of some variety,but I would also eventually like to build in online synchronization of the data where either database can be update each other based on newer information. Moreover, some type of encryption would definitely be welcome, and speed is a large concern
Synchronization: Primarily updates/additions/deletions will be done on the offline database, but ideally I want to have a web interface that will allow the same updates/additions/deletions and will be synced (beyond that I'm not sure exactly how to do it as I can model that based on what is most achievable).I'm wondering if there's any prebuilt engine that could handle the synchronization of 2 databases. I may end up having the web interface only be for additions, which would be significantly easier to sync.. and I may start that way, but i want to build with technologies that will best allow me to implement full online crud at some point.

Here is the issue: a client wants his entire equipment inventory accessible by persons navigating to his jquery mobile site. The inventory that exists on the desktop site was, as I understood, built with Flex. Is it possible to access this database for the jquery mobile site? I believe it is. I was then given this information from someone in the know:
Database:
mlxx.db.xxxxxxx.hostedresource.com

I am planning to develop a standalone application, which infact will be used for personal purposes. So only single user access may be there. I want to develop it in Flex. Just want some opinions from the gurus over here : Whether i should use Flex or AIR (I know only Flex, AIR i need to start learning)Which database i should use? SQLLite or HSQLDB or some other.

I am able to record sound from microphone, encode it using SPEEX and write into ByteArray. I want to play it back. If I try using Sound object the audio is messed up. Speex uses 16kHz for encoding and Sound Object needs 44.1kHz for playing audio. How am I supposed to play this encoded sound.

I have a legacy file format that contains sounds embedded in it (in various encodings). I would like to be able to play these sounds in Flash (Air?) by reading the sound bytes out of the file and instantiating a Sound object with them.
If the sound is unencoded (e.g., raw pcm), I've found that I can use the new flex 4 SampleDataEvent.SAMPLE_DATA event to play the sound.
However, if the sound is encoded (e.g., mp3), then I'm at a loss. The sound expected by SampleDataEvent.SAMPLE_DATA has to be raw pcm. From what I've seen, encoded Sounds can only be instantiated by [Embed]ing them, or by using a URLRequest with Sound.load().

I'm using mx.rpc.http.HTTPService to retrieve data from a web service. On the initial call to "loadWsData", HTTPservice accurately retrieves all the data.
However, on any and all subsequent calls HTTPService does not accurately retrieve the data; rather it always retrieves the first data set. I've confirmed that the web service is providing accurate data, both from web browsers and a ruby ws client script.

I have designed an application that will load the information from an XML File to a Pie Chart.
First my XML looked like this
[Code]...
Now this works perfectly and I can see the generated Pie Chart.But now let's say that I changed the XML in the following manner.
[Code]...
in the results event how do I access it? bookStock = evt.result.books.stock.bookinfo; doesn't work. I get a "Error: Unknown Property: 'bookinfo'." When I analysed the bookStock object I get this. How do I access the XML element now? Does anything needs to be changed here?

i have a datagrid which grows in size depending on the result of a call to my db. The call to the database returns an object with 30+ values for each row. When the number of rows returned exceeds about 80-90 the datagrid renders odd. It displays the first 50-60 rows fine but then it displays blank rows and they even continue to display outside the border of the datagrid.what is happening? Im using mxml webservice to retrieve the data.
<mx:DataGrid dataProvider="{resultsData}" rowCount="{resultsData.length}" allowDragSelection="false"
id = "confRoomLookupResults" width="948"

I'm using CF to retrieve values from a database that are then being stored in a datagrid in Flex. I then want to selectively take the value from one cell of the datagrid and store it as a string variable. I've searched around, but I haven't been able to come about a solution. The users will not be interacting at all with the datagrid as it will be hidden to them.

im working on:[code]For more detailed comprehension: corner is the black corner with the (i) and 'Promotion', text is some random text that can be displayed in the white remaining space, container contains corner and text, and finally this class contains container!I need to retrieve the event mouseevent.rollover/rollout from corner.And what's wrong?
1. When I put the mask on container (container.rawchildren.addchildren + container.mask = mask) and the dropshadowfilter on container (container. filters = [glow]), I cannot detect the mouse events.
2. When I put the mask on the promopanel (this.rawchildren.addchildren + this.mask = mask) and the dropshadowfilter on promopanel (this.filters = [glow]), I cannot detect the mouse events.
3. When I put the mask in a component and the filter in another, it does not work either.
4. If I remove the mask OR the filter, it works!! But I need them both...
So, does anyone has an idea on how to make this work? I've been trying to look for issues with filters, masks and mouseevents but haven't found anything that could enlighten this issue.

I recently found kirupa and started learning flash, now i've modified the code from Senoculars XML search to search through keywords for my images and display the results. When you click an image it gets magnified. My problem comes from wanting to be able to use a button to change between the images, like in this photo gallery.My problem is getting the number of the image I just clicked, if I can get that, writing the function to step between images will be no problem.
Code:
DisplayNodes = function (nodes, field_txt) {
item_xcount = 0;
item_ycount = 0;[code],,,,,
