ActionScript 3.0 :: AIR: Way To Specify Where To Start Reading File?
Sep 23, 2009
I have an AIR app im currently developing. And often I am reading 150+MB CSV files. To load the entire file takes a long time, and is quite a memory hog. Im currently loading the entire thing, but the software often only needs part of it, but then will need other parts later.he files are about 1.7Mill lines long, so what I am trying to do, is read the file, but just load every 1000th line. then load all the lines of just the part the person is looking at. But when the look at a different part, I need to load that part in full.

I turn to you for help, dear sweet Kirupa Forumites. First, let me explain the problem: I have a flash file reading an external text file for the content. Everything works perfectly for nearly everyone - you click a menu button, and the content text comes up fine. However, a couple of people have found that the text shows up as "undefined". I have checked the player versions of the people where it doesn't work, and it is the same as for those where it does work, so that ain't the problem.
I don't understand why it works perfectly for nearly everyone, but a small number of people have this "undefined" text problem. It seems to be a problem with loading the external text file, but I don't know why. I have a main flash movie, and load the text in the first frame, using the following:
var my_content = new LoadVars();
my_content.load("content.txt");
my_content.onLoad = function(success){
if (success){
[Code]...
I then have a couple of dynamic text boxes in the main movie - one called ErrorText (for displaying an error message to the user) and one called ContentText (for displaying the content). I use an external menu swf which jumps to a specific frame in the main movie, depending on which button is clicked. Actionscript on the main movie frame for the first button does the following, with the other frames similarly configured:
ContentText.htmlText = my_content.content1;
stop();
My external text file is properly configured (content1=blah blah&content2=other blah blah) etc.
Does anyone have any advice on how I can solve this particular weird problem??

I would like to have two applications communicate with each other. One app is a Flash running the browser and the other one is another app of ours that is distributed as *.exe file. We need the C/C++ application to read some info out of the SOL file, that is written by the Flash app.
Any other mean that can be used to read the SOL file from a C/C++ application? How often is the format of the SOL file being changed ?

What I have so far...sure there is a better way to do this and as I learn AS3 I will figure it out. The following is what I put together where I now have three instances of the segmented thumbnail button that shows an image when cliked on. What I figure out why it only reads the one xml file.
My XML files: images, images_a, images_b
<images><image full="images/full/image1.jpg" thumb="images/thumb/image1.jpg" /> <image full="images/full/image2.jpg" thumb="images/thumb/image2.jpg" /> <image

I'm trying to read a url from an xml file and attach an onRelease event to a movieclip that opens the url when clicked.
Code:
var thelink = getValue(findNode(i, "link")).toString();
var thelink2 = "../news/Press Releases/testpdf.pdf";
if (thelink <> "")
{
tempMC.bat.onRelease=function(){ getURL(thelink); }
}
If I use the "thelink" variable as input to the getURL function, I get a "Page not found" error.If I use the "thelink2", it works as expected.When I look in the debugger, "thelink" and "thelink2" are identical!Here is the code for the findNode function. I've had no problems before with this code, so I don't think the problem is there.
Code:
function findNode(node, nodeName)
{
if (node.nodeName==nodeName)

I was wondering if there was a way to have a flash file read its own flash name and use it as a variable within that swf. ie, 05.swf. I would want 05 to be a variable with the page.

I have a couple variables coming from PHP. So for example if my PHP looks like this:
PHP Code:
$qry = "Select * from memory";
$result = mysql_query($qry);
echo "memory=";
while($resultset = mysql_fetch_array($result)){
echo $resultset['name'].";".$resultset['memory'].",";
For this the output from the PHP file would look like this:
memory=Person2;Memory2,Person1;Memory1,
So basically the comma represents a new record in the database. So basically in my text field I'd like the following result to happen:
Memory: Memory2
From: Person2
Memory: Memory1
From: Person1
So take the first record and display it like I've shown and then have a couple break lines (not sure how to accomplish this either) and display the next record that was separated by the comma.I have the following AS code which works for one variable but I have more then one like above:
ActionScript Code:
files = new Array();
lv = new LoadVars();
lv.onLoad = function() {

I am making a random name chooser for a class (using an array to read from 28 names). I was wondering if it is possible for flash to read an array from a notepad file. [code]Is there a way to make it so that instead of having to edit the Fla file to edit the names, I can just make a notepad file with the array and _root.NumberOfStudents variable so that it can be edited from year to year easily?

Quick question. Ofcourse I know that you can read flash variables from a text file, which is formatted like: @var1=firstVariable@var2=secondVariable and so on.But is there a way to read normal text out of a textfile? Is it through the bytearray class?

I am trying to import an xml file with multiple sections of HTML. It looks like:
<?xml version="1.0" encoding="utf-8"?>
<htmlcontent>
<application>
<title>Site Deployment</title>
[Code].....
Whenever flash sees an html tag such as <p> or <img src=""> it stops reading the xml file at that point. I currently have it working with each application in its own xml file, but that is messy and I would rather it all be in one place.

pulling both a variable and an array from a text file (.txt). In my case I have the following:A flash file (.fla)A text file (named MyTxtFile.txt)Now, I just need to be able to pull an array from the txt file. Is it possible to do this? On the main timeline of my flash file I have the following:
Code:
MyArray= new Array("Pizza", "Cheese", "Fish");
_root.NumberofItems= 3;
My goal is to have the "MyArray" array in the text file so that I can edit the values from the txt file.Then I have a button on the main timeline ("Item_txt" is just a dynamic textbox in the flash file):
Code:
on(release) {
_root.Item_txt = _root.MyArray[random(_root.NumberofItems)]; }
I want to be able to update this file often, so I thought it would be handy to just "store" an array and a variable in a text file. Let's say in MyTxtFile.txt I had the array "MyArray" and the variable "NumberofItems". I could just update the information in the txt file and it would update the Flash file.
Edit: Would it be possible to store a string in a text file, then have that string put into a blank array? For example: If I had "cheese", "stars", "playdoh" in a text file and then I pulled the string into flash using the LoadVars class could I have the code in my time line set up like this:
Code:
_root.variable1 = "";
var ARRAY:LoadVars = new LoadVars();
ARRAY.onData = function(thetext:String) {

If it's possible for Flash to read an XML file and look for element names rather than using myXML.firstChild.firstChild.firstChild; etc? So say I have the following:
Code:
<music><song>Song 1</song>
</music><food>
<curry>Tikka</curry>
</food>
Rather than using "firstChild.nextSibling" etc to navigate itself to the Food element, is there a way to just have something like "find the food element in the XML and return its childNodes"? It makes more sense to me this way because then it doesn't matter how you structure your XML file. And if you change the XML structure later on.. you don't then have to update the Flash as well. My reason for this is i'm using Expression Engine CMS and want to pull the data from that into Flash.

I am calling one method at an interval of 3 sec. This method reads a file from server and then display its content. The file which is getting read is a log file which gets updated at regular interval. The issue is once some content read by AS then it is not getting updated that means after every execution of the function content of src variable below remains same even thou the source file is updated.
