Flex :: Barcode Component For Barcode EAN 128 With Application Identifiers?
Jul 16, 2010
I am looking for a flex component to generate a barcode similar to the one below. [URL] I have found a similar plugin, at [URL]. But could not replicate the Application Identifiers by just using the "( )"
I am currently working on software for student attendance. I use the flex / flash and php to create the software but I faced a problem barcode scanner, can not connect to the application to call the data from the database when students scan the barcode printed on their student card.
Want to add following feature to my web application: To decode barcodes generated by this script with webcam and use values in PHP web application. Is that possible? if yes how?
I am currently working on software for student attendance. I use the flex / flash and php to create the software but I faced a problem barcode scanner (Motorola-type barcode scanner Symbol LS2208 Laser Barcode Scanner USB), can not connect to the application to call the data from the database when students scan the barcode printed on their student card. make the script so that it can run on flex / flash and php. it makes me crazy for a week to seek a way out. (I have not mastered the java script)
I'm looking for a barcode reader using a webcam in flash builder 4.6 for mobile application. I have tried the following link here but didnt work its showing "Nothing is decoded" If you tried to scan a Barcode/QR code using mobile device.
working with Flex4 AIR app, using this component I get data from the barcode reader,
<s:TextInput id="barcode" enter="showBarcode()"/>
Then for handle the enter event, wich is automatically triggered when reader finishes its reading
private function showBarcode():void{ Alert.show(barcode.text); }
Ok, very simple. But my problem is: the text showed in the Alert Box is incomplete, it misses one or two digits (last) or it just shows the entire text in the TextInput component (correct view)
I already test my BC reader using the notepad, and it's fine.
I have tested same code using MX components in Flex3 web app, and there's no problem.
i'm interested to write barcode scaner with flash which would work for any platform that has built-in camera and while scanning wich automatically uses the camera for barcode reading . how to accomplish this or have a guide for this?
I have a USB barcode reader attached to my tablet (running Android 2.2), it seems to work, but how to read the date from it? And which event is triggered when it is scanning?
I'm creating an online application to manage a shop. The user enters the item's barcode using a barcode reader then i am how read the barcode values using AS 3 ?
I'm trying to find a way of playing a presentation with product information and movie animation (flash or HTML with embedded movie) using a barcode scan as the activator. Ie, a customer would scan 1 of around 20 products on a barcode scanner, and product info and a movie would play. Anyone have any ideas of how this can be done. I've been out of the flash world for a while, so not sure if it has the capability. If someone has the ability to put this together, there would be some $$ involved. brendan.lake@circle-square.net
A Flex components values are initlized by init methord. In an application flow, How to refresh a mxml component data value ; as init is callled at the start up it self only.
eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )
I'm making a UI for a component in Flash. I wanted to use Flex and have had no luck getting the onUpdate exernalInterface call to fire properly. I'm referencing the functionality described here: [URL]. First off, I can't embed the SWF in the FLA. It just won't start the Flex SWF. Even using the external swf, it seems that the onUpdate function is either called too early or not at all. Here's what I've tried:
Tying the externalInterfce declaration to the initialize, preinitialize, applicationComplete, and creationComplete events. Sub-classing my application and putting the externalInterface in the constructor. Neither of these options work. When I create a basic AS3 project in Eclipse and put the externalInferface in the constructor, it works as expected.
Is there a way to tell at runtime if a flex UIComponent is in the user's view or not.For example, if I have a tabNavigator with a combobox on each tab, is there a property of the comboBox that will tell me if it is visible to the user or not when I switch from one tab to another?I know it is not the comboBox.visible property. That is set to "true" for both comboboxes. I want a property that will change when I switch from one tab to another making the comboBox visible to the user. I don't know what that property is.
I created separate own canvas component for Home page, Contact page, Rules page etc.In my main application it has link button like Home,Contact,Rules in application controller(child state) . [code]...
So I'm using a custom auto suggest component that I found online at [url]... The background color for the item is set within the following folder[code]...
I use this component from within a component I created called "position.mxml" that is located in a folder named "modules". Is there any way that from the position module, I can change the background color of the autosuggest box?
I will need to execute a function in a comp1.mxml from main.mxml through event, I found it difficulty to understand and unable to get it work.[code]...
I know it is possible to develop a full flex application using AIR for android but what I need is to embed a flex component into an already existing classic java android application.
I found some flash players in java but they all either require a JFrame or include of specific windows dlls.
I would like to send variables or parameters from Component to Main (MXML) Application. Like my component is FileUpload.mxml and would like to forward the uploaded file details from FileUpload.mxml to Main.mxml.
I tried the following procedure :
com:FileUpload id="fp"
to get the reference for the FileUpload component, however, I am unable to get the variables from the FileUpload.mxml file.
I'm new to developing iOS applications and my school gave me approximately 5 months to develop an iPad application. I have no knowledge or practice on Objective C so since Flash Builder 4.5 allows the development of mobile applications (and I have experiences with Flash Builder), I decided to develop my application on Flash Builder instead.
Everything is going fine until I was told to include a SplitView in my application. I implemented a List on the left side of the application. Clicking on any of the list items will navigate the user to a to another view but i also included and retained the list on the left side of the new view in order to simulate a "SplitView".
Initially it felt as though it will do the job of a SplitView like how it does when I attempted it on XCODE but it doesn't look or feel natural. I found this video which shows that it is possible to create a SplitView on FB but I've cracked my brains and I really can't figure out how it is done.
I need to be able to call a method from a component located under the main application in Flex 4. Can anyone tell me please how to do this without using FlexGlobals please?[code]
In my main application I have a viewstack with 3 child views. In the viewstack change handler, I programmatically change the selectedchild property.
I understand that the initialize method for the view is not called every time I change the selectedChild Property. So I tried to invoke the init method programmatically too..
I am trying to create my first real world Flex application. I will have a lot of different data entry / data view screens so I thought I would create many different components to deal with each different type of data that was being returned. I have a MXML application called Layout, and have component called "Navigator" which controls the menu, as well as a ViewStack called "MainContent".
I want the Navigator component to change the ViewStack on the Layout application to that of another Component (each Component is embedded within the Canvas of each ViewStack). I have a click handler on my Navigator which looks like this: Layout.ContentFrame.selectedChild=event.itemRenderer.data.clickValue; However it shows the error "Access of possibly undefined property ContentFrame through a reference with a static type Class." Is my approach a good way of doing it? I have attempted referencing it using FlexGlobals.Layout and topLevelApplication.Layout... neither of which work?[URL]
