I want to build a basic calculator in Flex, My calculator will do the process that is entered in the text box and it will show it on that text box.For an example :
Text Box = "10+1"
Click the button
Text Box = "11"
I'm trying to build a calculator in Flex / actionscript 3 but have some weird results using the class Math :
trace(1.4 - .4); //should be 1 but it is 0.9999999999999999
trace(1.5 - .5); //should be 1 and it is 1
trace(1.444 - .444); //should be 1 and it is 1
trace(1.555 - .555); //should be 1 but it is 0.9999999999999999
I know there are some issues with floating point numbers, but as you can see, it should at least fail for all of my examples, am I right?How the problem is solved in other calculators and how should I proceed in order to build a usable calculator in Actionscript 3 .
I'm trying to make a basic flash calculator except it only has to be able to square the number provided by the user, I have followed many tutorials but I keep getting the NaN as the output. Here is the actionscript:
import flash.events.MouseEvent;
square_btn.addEventListener(MouseEvent.CLICK,
squareClick);
[code]...
I also need to have Input box and Error Messages & Highlighted Input Box.
I'm trying to build a basic quiz - there are 6 questions and I want it to display a score at the end. Everything works and it shows a value at the end (but always '0'). It's not keeping proper scoring as users go along, it should be adding '1' point for each score, no matter what option is clicked it just traces '0' in the output window. Maybe something to do with the variable or? Kinda new to Flash, the chunk of code I believe to be the issue is below,
import flash.events.MouseEvent;
//varialbe for keeping score
var score:Number = 0;
//event listeners for button clicks, which will adjust the scoring array

In TFS 2010 build, I have a new build and I want to call an ant script that builds Flash. How do I call the ant script? Also How can I compile the Flash directly? I've seen the Power Tools and this question but it doesn't help me as we don't have TFS 2008. I can't find any documentation on how to use the power tools except the 1 sentence on the bottom of download page saying to create your build the old way and import it (which isn't very helpful). I've installed the power tools on the agent computer but I don't see any new options in the Toolbox when I'm designing the build flow.
View 2 RepliesI just started working with ant a few days ago. Right now I have a general buildall.xml which should call each project's build.xml. Because some projects depend on each other, I need to rebuild some other projects which depend on it. This isn't a problem--I'm just setting the depends property of the target. However, ant is always building the dependencies, even when the files haven't changed.Let's say project1 has no dependencies; project2 depends on project1; project3 depends on project1, 2; project4 depends on project1, 2, and 3; and so on.I could hack a solution which looks at project K, and checks if project 1 .. project K have updated files using uptodate. If so, then run the target. This is messy and appears unnecessary.
What is the cleanest way to implement this?EDIT: So I decided to just hack in a bunch of targets, "check_projectK" where it does the uptodate checks on all of its source files, its build file, and the build files of the 1 .. K-1 projects. Due to dependencies, this is always handled correctly. However, this is still a large amount of copy and paste for a large workspace.
How swffit (http://swffit.millermedeiros.com/) can be used? I mean in my project I have dynamically expanding flash application, so once the expanding part riches the bottom I see standard flash scroll bar. Not browser scrollbar...
Here is how I defined my application:
public function addPanel(evt:Event):void
{
var panel:Panel = new Panel();
panel.name = "new";
panel.title = "new";
panel.height = 30;
panel.width = 100;
this.addChild(panel);
SWFFit.fit('my_flash', 800, 600);
}
public function main(event:Event):void{
SWFFit.fit('my_flash', 800, 600);
}
]]>
</mx:Script>
<mx:Button label="Add" click="addPanel(event)"/>
The html file (same as described in docs):
<html>
<head>
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript" src="swffit.js"></script>
<script type="text/javascript">
swfobject.registerObject("my_flash", "8.0.0");
swffit.fit("my_flash",800,600);
</script>
</head>
<body>
<object id="my_flash" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="100%" height="100%">
<param name="movie" value="Sample.swf" />

Will be happy to hear any feedback,
Added fixes described in answer 1. but come across interesting issue: e.g. browser scroll bar appears only on browser window resize, not when clicking add button...

View 1 RepliesI'm trying to build a flex project, linking it to some RLSs. When setting up the project in Flex Builder, the corresponding "build configuration" (that I got by adding -dump-config to the compiler options) generates (among other things) a tag like this :

Using FDT, when I have a debug configuration with several operations in the launcher chain and the final launcher opens in Flash Player, how can I retrieve the build output from the console once the build is complete and Flash player is running?
It seems that once Flash Player has started the console clears to make way for the application's trace output, but I need to be able to look back over the events and build times for each item in my launch chain while Flash Player is running. Is there a setting I can enable to either log my build output to a file or to preserve it in the console?
Edit: I know I can still read the info when building normally, this question is specifically for building with the debugger.
I can use Maven with FlexMojos to generate swf file, but because I have several mxml files need to build, could I build them in 1 Maven pom file?I know if I separate them into several projects, Maven can build them. But because these mxml files have some shared functions, it's not easy to manage if I separate them.Another question is the size of swf file. The original file size build by Flex builder is about 80KB, but the file size by Maven is about 800KB. Is it normal?

View 1 RepliesI have an .SWC library with a style.css file inside. The .SWC file is added to my project and the style.css is used this way: <fx:Style source="assets/style/style.css" /> If I want to build my project with an ANT-script it says that "the external stylesheet couldn't be found". In ANT you need to write the path for assets with an leading "/". So this would work: <fx:Style source="/assets/style/style.css" /> But in this case it isn't possible to retrieve the style.css from the .swc as the compiler says that "the external stylesheet couldn't be found". Is there any way to use the style.css inside the .swc AND use ANT to build the project?

View 1 RepliesI'm trying to learn how to build interactive data visualizations, and I think I want to go the Flash/Flex/ActionScript route instead of using Processing.The problem is, I've never understood what the difference between all three is, so I don't know which one I should be learning.It sounds like Flash is more for designers/non-programmers, Flex is more for programmers, and ActionScript is just the programming language used in Flash and Flex (i.e., Flash and Flex are to Actionscript as the iPhone SDK is to Objective C...?). Is this correct?If so, I'm a programmer, so it sounds like I'd want to go either the Flex or ActionScript route. What's the difference between picking up an ActionScript book vs. picking up a Flex book?
