Requirement: Create single very large bitmap data which contain some 30 PNG images loaded and for each image it should have some text. Images and text are loaded dynamically (AS2 code. Images are stored in a remote server). The bitmap data display should show 8 images at a time and corresponding text. We can see rest content by scrolling (kinetic scroll is implemented). How can I go for it?Some questions:Is there any limit for size of bitmap data ( As per link there is restriction on the height of the bitmap we can create in AS2 (max value is 2880 which is not enough for some 30 element list If we create individual bitmap data for 30 individual PNG files, we find some jerks in scroll. How can we have smooth scrolling?
View 5 RepliesMy data grid is displaying stale data, rather than the real time data available in it's data provider (array collection). I've tried refeshing the data in the collection, but that has no effect. Below is my code, does anyone see what could be the problem?

I have an actionscript function which is supposed to launch a panel and then fill in Networktopology data inside it.As, network data is too large that it consumes much time and makes browser hang!Even I tried to display busy cursor which also stopped spinning when data was being processed.How can I ensure processing large amount of data does not hang the browser.
View 3 RepliesIs there a way for different flex swf's to send large blocks of data between each other without using localconnection which is size limited or using sharedobjects. This needs to happen on the client without server communication.
View 2 Replieshow much memory (and swf size) the various built-in data types take up in actionscript 3? I'm specifically interested in int, Number, and (dense) Arrays or Vectors. I'm working on a project where I need to embed large amounts of structured array data, which is already in C++ format, so porting is just a matter of copy-paste, search-replace. I've already had a look at Adobe's lowdown on datatypes but it's not specific enough, and doesn't mention Arrays, etc.

how to display a large amount of text inside of Flash CS4. I have a 46 page pdf I would like to display but I would really like to keep it internal to Flash...I don't want to link it out to a separate html page if I don't have to (i.e. through a URLRequest). I would like to have one self-contained swf file.

I'm working on a flash cards application and am using an ArrayCollection of Objects to store each cards individual data. When the user click the 'save' button, the text from the two textAreas and the 'title' textinput are stored in the AC as one object with .title, .side1 and .side2 properties that contain the text from the flash card. I have made a List in a separate class I want to have display the title of each card the user has created, but after days of researching and looking around, I still cannot get the display to list the titles.
Part of my NewCard.mxml:

My current little problem, which I believe is my last one (yay) involves feedback. I've got a frame at the end with a list of the questions and whether or not the user got it right. I've set up two little arrays, one with the question number (because this is a random quiz) and one with corresponding indexes saying whether it was correct or incorrect (well, true or false at the moment). The intent is to associate the question number with feedback (either stored in AS or XML) and return it when the answer was wrong. All that side of it I can do, that's not the problem.
The problem is... I have very little idea on how to display this info! I'd use a dynamic text box, but I don't think you can put line breaks in them (without using HTML coding). I have been thinking about either manually or dynamically creating dynamic textboxes (or mcs with textboxes in them) and then adjusting the text, but the designer side of me cries when faced with the problem of some feedback having one line, with others having three (and everything in between).
Previously I post a discussion on this matter on Flex Adobe forum and still don't understand what needs to be done. So, I'll try my luck again on stackoverflow. I'm using drag and drop data binding functionality in flash builder 4 on a data-grid. However, the data I need to show need to be query from another object.

I have some DataGrid with editable rows, which has also an option to add new row 'dynamically'. I mean, last row has some default data (e.g. "CLICK HERE TO ADD NEW ROW") and when user clicks on it, he can edit that value and new row will be eventually inserted.
However, I also have a column in same DataGrid which doesn't come from DataGrid's DataProvider. That column is used to delete specific row and it should only display clickable image with associated mouse click action (within custom itemRenderer).

I'm trying to display query data into multiple TextInput Fields in Flex.

This is what I'm trying but all that displays is [object Object]
I think I need to define the database field I'm wanting to display, but I'm unsure how to do this as TextInput fields don't support dataField or labelField properties. Is there another property I don't know about? How do i go about fixing this?

View 2 RepliesMy group is working on a Flex/AS3 scientific web application that is data intensive. Luckily the only plots involved are line charts. However, each line chart may have multiple traces (up to 24), and each trace may contain up to 2000 points. The user will need to zoom in and out and interact with the data (e.g. data tips, etc.).
The response I'm getting from developers is that's a lot of data to render in a plot in Flash. For reasons beyond the scope of this post, we can't sample the data to reduce the size (this has already been done and nature of the data prevents further sampling).
Rendering speed is critical for this app. What kind of rendering speed should I expect the Flex 4 line chart component to provide for a given number of points (e.g. 1 second to render 1000 points?)
Are there products available that handle plotting large data sets better, which can be incorporated in Flex (I've seen FusionCharts and ZingCharts online but have no idea how they compare with Flex's components)? Of those, which are easy to develop with while still providing a lot of flexibility in look and feel?

I have read and successfully created .db's using this tutorial.[url]...
However to populate the database I use flash? So this kind of defeats the purpose of it. No point in me shifting a massive array of data from flash to a sql database, when I could access the data direct from the as3 array?
So maybe I could create the .db with an external program? but then how would I include that .db in the apk file and then deploy it to users android device.
Or maybe I create a as3 class with an xml object init and use that as a means of data storage?
I'm developing an application using Flas Builder / Flex for Adobe Air. This application will be processing a large set of static text (100 - 200 MB) using a variable set of processing instructions.The target platforms will be iOS, Android and Desktop.The data set can be either one large XML file or broken into a bunch of XML files about 3MB each.This will be decided at design time.From your experience would it be better to store the text in an Adode Air database or a set of XML files for best performance (including speed and battery life)?What other considerations should I take into account?

View 1 Replieshow "you" would do it and then deciding my strategy from there.What I'm setting out to do is as follows:I have a UI with about 10 sliders and 10 buttons.I'm using Senoculars Virtual Mouse class to record all of the users interactions into arrays (basically [x,y, action, time, value]) and then after a decided time (say 3 minutes) I play the users interaction back to them.All of that works fine but now the data is not persistent.I would like to be able to store the interaction data somewhere and then a user can log out, log in and view their previously saved interaction.how would you go about saving this data? I was thinking about storing it in a XML file but I'm concerned that the file would wind up being ridiculously huge. If a user drags a slider from left to right just once thats saving [x ,y action, time,value] 42 times.
View 3 RepliesI'm currently using XML to import geo-location data to my flash application.Even though my XML scheme is about as small as can be, I still feel i would do better downloading the variables as text and exploding them. If i manage to change the xml to raw text I can compress the data to about 35% of the original size.I want to load the data in the form a_b_c_d-e_f_g_h.So, to the question; how do I explode a datastring in flash?
View 2 RepliesI'm building a sidescrolling world where you can move around.The idea is that you should be able to move to any point in the world, as well as travelling really fast.I'm pregenerating a long list of data about objects to place, their positions etc.
Now. When moving to a point far away from current position I don't want to loop through the whole list of objects to find what objects should be seen and not, so I'm thinking I should divide the position list into sections, each covering an area equal to the visible area. That way I would only have to roll through the lists closets to the new position.This would however result in an array of thousands of elements each consisting of about 20 objects and I'm figuring that might not be very healthy.One solution would be to split everything up further so that in the end I would have a handable nr of arrays containing a handable nr of elements.
You're probably thinking I should generate positions on the fly, but since one place in the world can be revisited I need to store all positions.
I've got a small problem with loadvars. I want to send data from Flash to PHP, which usually works well. But right now I need to send "larger" amounts of data around 10-20kb and loadvars doesn't work anymore.
Using loadvars to open browser-windows seems to work fine, but I want everything to happen inside of flash.
The code is:
Code:
datastring = "1, 2, 3 (...) 4998, 4999, 5000"; // long text
loadstring = 'save.php?data='+datastring;
db = new LoadVars();
[Code].....
Works fine with small text, with big text nothing happens. How to do this the right way?
Edit: Loadvars seems to work up until 4050 characters, 4051 and it doesn't send anymore. But I can't really split the query..
I have brush off my Flash skills. Usualy I work in FW but now I have to create a banner in various large sizes but with very limited file size so I turn to Flash. My animation needs are very modest: moving ease in/out, rotate back forth and maybe a fade. Have any of you guys have some tips&trix for getting as much (simple) animation with keeping a small file size? Or point me to some tutorials?
