Will ASP.NET Form Get value from Barcode - asp.net

ASP.NET Form. If running a form in a browser on a small (Android) device with a barcode scanner, will the scanned barcode go into the ASP.NET textbox? Or I need to add something to the application?

Well, it going to depend on which of the 150+ barcode scanners you decide to grab from google play.
However, the answer is yes, or no. It will depend on the kind of scanner.
If you download just a scanning application (software based - not built in scanner).
The reason is Android (and even iOS) don't allow one application to set focus, get/grab/take data from other applications. Nor is the reverse allowed. If that was possible, then the app could also get/grab/take values from when you are say running your on-line banking application.
I don't think Android thus supports focus to another application during scan that has focus. Now if this is factory supplied software on the phone? Then yes, this works like a desktop keyboard "wedge". That means the program does not know if you are typing from keyboard, or input is from the scanner (hence the name keyboard wedge). These will work with a web form.
However, we now seeing the rise of software based keyboard wedges. That means the software scanner is installed on android as a custom keyboard. And this in case, then once again, it will work in a web form.
So, for devices with a built in scanner? yes, that will work in all applications. For a software only (uses built in camera), then again, this is possible if the software in question works as a keyboard/wedge scanner.
If you going to adopt android scanning? then use a purpose built Android scanner.
And another possible if you want to use a software scanner? Write a small android application and have it talk to your web site. This I think is the best solution, but of course means you have to adopt some Android dev tools.
So how this works will depend on if the android device has a built in scanner, or it is a software + camera based scanner. However, it would seem that even now installable software based scanners in theory can be made to work for any application since the application is running and behaving as a user installed keyboard.
So, you have to check the particular device. The answer is not in all cases, and the answer depends on if you using a Android device with a built in scanner, or you looking to use any Android phone as that scanner.

What is the best way to convert Flex App for windows mobile?

Ok, so I have a Flex application developed using Apache FB 4.14 SDK. I got it working and approved on App Store and Play Store. Now my client is looking to port the app on Windows Phone. I tried some googling but all I found is about Astoria project, which is recently dropped by Microsoft. So My question from you folks is what is the best way to port the Flex code for Windows phone with minimal efforts?
Sadly, there is currently no easy path from Flex to Windows Phone.
The road map also states no current plans to add support: http://www.adobe.com/devnet/flashplatform/whitepapers/roadmap.html
You will have to port your game to a different engine. How much work that is, and which engine you should use, depends a lot on the nature of your app.
It also depends on if you want to make a Windows code base just for that platform, or if you want to port to something to have one code base for all mobile platforms

Displaying different stuff to multiple Projectors.

I want to connect multiple projector to single laptop, I found about VGA Splitter (http://www.kvmswitchtech.com/vga-splitter-350mhz-8-port-p46359.htm) which can use to connect multiple projectors to single PC.
But I don’t want to display whole screen in both Projectors, in short Projectors should display different stuff at same time.
For Example:-
Projector 1 can Display Power point Presentation and Projector 2 can Display the running movie in player.
I got below set of Questions
Is there any Software available to perform this operation?
If I want to write my own application, Is Directshow (Provided by Microsoft ) is good one to start?
Is there any other VGA Programming language available?
Is there any Software available to perform this operation?
The primary question you are going to get here is how the projectors are connected to PC. The device might need specific integration and you're moving the item #2 below immediately. Otherwise it can be a sort of secondary monitor and you can extend your desktop over it, and then any full screen application running on the secondary monitor is going to be projected.
Perhaps, you will find more software choices going to SuperUser.
If I want to write my own application, Is Directshow (Provided by Microsoft ) is good one to start?
As mentioned above, the hardware might need you to use specific SDK from the vendor and this is your starting point. DirectShow is the API that covers multiple related tasks and might be of use here:
it is capable to built media pipelines terminating at DirectShow-compatible video output device (the projector might be not might be not capable/compatible)
it allows you to play media files into your application and otherwise control video/audio and integrate it into higher level software
DirectShow as API does not fully cover requested task, but it definitely relevant might be used in the in-house built Windows based app.
Is there any other VGA Programming language available?
The "language" is not actually language and it is how particular device is integrated with PC. This is typically covered by hardware vendors who provide the hardware with accompanying development kits and samples.

Replacing Apache Flex with HTML5

I am writing an application which requires access to the microphone of a device to determine instantaneous volume levels. The app will have a web version, iOS version, and Android version, and must be compatible with as many devices as possible, since the particular user base our application targets may not be able to switch browsers easily.
At first, I looked into using HTML5 for my application. However, it does not seem to be viable for my purposes, because I can't find any cross-platform way to get instantaneous microphone input and many users may be using an out-of-date version of their browser, which would not support HTML5. Is there any tool which alleviates these challenges and would allow me to use HTML5?
As a replacement, I began looking into Apache Flex. It seems to have all of the features I seek: It is cross-platform, allows me to access microphone volume levels, and will work even on very old devices, as long as they have Flash installed. However, many people predict the imminent death of Flex and strongly argue against using it, opting rather for HTML5. For my purposes, is Flex an appropriate tool, or would it still not be recommended?
You can achieve it by using PhoneGap or similar backend app which can host a webview and allow you to access native api through JavaScript or JSObject.
For front end, you can use HTML and keep your UI standard across all devices/platforms.
PhoneGap is little bulky but on Android and iOS, you can create a minimal app by hosting WebView and customize it to create JavaScript bridge and write your own native api.

Web page to access bluetooth device

I have made an asp.net application designed to manage and optimize warehouse statistics info. The user had to collect and enter all the info manually so I thought it would be way better to get use of some bar code devices that uses bluetooth for communications to get that info on an automated process.
So I developed an Internet explorer extension that managed the page requests for the bluetooth device and made posts inside a control container with the data.
The fact is that this extension gives me plenty of problems, having to redo the pairing of the devices every now and then as it looses it's functionality after some unknown event. I don't know if it has to do with windows updates or accounts management and rights.
Does anyone knows an alternative, that would be more stable? Perhaps with Java?
Cross-browser would be a plus. In fact I'm headed at mobile devices using android. For the moment, only windows tablets are compatible.
Thanks.
if you are targeting windows tablets, why not using HTML5+Phonegap. This might help.

Will a Flex app run on a mobile device?

Can a Flex application that was designed for use on a PC be run on an iPad, iPhone, or Android-based mobile device?
Seems like a simple enough question. Visiting http://www.adobe.com/products/flex.html yields a picture of a dude running a (presumably) Flex application on an Android. So at first glance, the answer would appear to be "yes." End of story.
but yet…
There is so much (mis)information out there on various tech sites that suggest Flash-based technologies simply won't run on iOS or other mobile platforms. Why is this? Perhaps they mean to say that Flex won't run "out of the box" and requires a plugin? Or do they mean it won't run at all?
Every time I think I've reached a definitive conclusion, some post on SlashDot or CNET directly contradicts it. So what's the scoop? Can one take an existing Flex application and run it on iOS/Android? (I realize there are screen size issues to consider so the app might not run effectively. I just want to know if the runtimes are available on the mobile devices to allow the Flex app to launch at all.)
Sorry for the noob question. My background is WPF / HTML5. Adobe technologies are completely foreign to me.
I wrote a lot below if you'd like to read it enjoy, if not sorry for taking your valuable bytes :) I directly answered the questions up here first:
Why is this?
It's a confusing matter read below for the why details.
Perhaps they mean to say that Flex won't run "out of the box" and requires a plugin?
Or do they mean it won't run at all?
Using the flash builder tools (the bin folder in the SDK) you can compile for native desktop application, desktop web browsers, native iOS application, native Android application. Android with FlashPlayer plugin installed will show Flash content within the web browser, iOS will only run the ones compiled with AIR, not in the the web browser but as a native app.
Every time I think I've reached a definitive conclusion, some post on SlashDot or CNET directly contradicts it. So what's the scoop? Can one take an existing Flex application and run it on iOS/Android?
Yes, if using AIR and run as a native app on all three platforms (the desktop Flex API is for the most part a superset of the web Flex API), your other points about performance and form factor are valid and should be considered though. The nice thing is you can write your model/controller code in a common library in AS3 then write separate presentation layer interfaces that all share the library.
Here's the very long version:
Using the flash compiler results in "bytecode" in the form of a file with a swf extension using the swf format, you can read a ton more about that here:
http://www.adobe.com/devnet/swf.html
To interpret the file you need some sort of run-time similar to some degree to running WPF/XAML/C# within a .NET framework context (either desktop or using silverlight on the web). In the case of adobe technologies (rough equivalence):
AS3 = C#
MXML = XAML
Flex = WPF+WCF (client side RPC not server side)
Flash Player = Silverlight
AIR (Adobe integrated runtime) = .NET
Framework Redistributable .dll(s)/.so(s) for desktop OSes
(Read this list very loosely please, I know XAML is preserved in the MSIL or whatever which is different because MXML is compiled to AS3 and only if a debug flag is set on the compiler does it include the debugging symbols, there's certainly tons of differences but I think this is an easy and correct enough model to use)
On iOS the browser does not allow for plugins in the traditional sense of netscape browser plugins or ActiveX plugins. For this reason you'll not be able to execute a plugin ie flashplayer or silverlight in the browser. Since Adobe did release a flashplayer for Android devices that does run in the browser it will work on those devices in the browser, however they have essentially thrown in the towel for supporting this long term, as they have to support the majority mobile device platform, iOS, in order to remain relevant (this was I think more a collective throwing in of the towel by Google, device manufacturers, carriers, Microsoft, all just following suit and trying to make the best business decision, WebKit and V8 or SpiderMonkey can probably do 99% of what Flash can do and better in some cases and WebKit will hopefully not splinter and will remain open source... frameworks and the browsers just need to get fleshed out and stabilized).
If the user installs AIR (or the runtime is packaged with the app) then a Flex/Flash (that is stuff coded in AS3 and/or MXML and compiled to a swf) can be transcoded/packaged to be interpreted by the run-time for that device correctly (be it iOS or Android or whatever RIM did, I don't think they have AIR for Windows Phone 7 and Win8 on ARM won't support browser plugins either). Part of the confusion is possibly from the fact that Apple denied the distribution of Apps that were "cross-compiled" which kept AIR out of the list of options for iOS for a good year, just after Adobe started announcing it was usable for that purpose (kicking Adobe while their down). Another part of the confusion probably comes from real vids of people who have 1 hacked their device or 2 were able to get open source alternatives to the flash player run-time to work on their iOS device (gnash was one I'm aware of from some occasional Linux tinkering, also possibly FAKE vids).
You can run Flex applications on mobile devices, but you cannot simply run any Flex project.
In Flash Builder ( Flex Ide) or in Flash Professional you can create mobile projects. These projects generate native applications for iOS and Android.
Last time I tried, the result and the available components where less than what I expected. So, if you can, I'll much recommend you go for something like Appcelerator.com or similar, which turns HTML5/Js code into native apps. I tried them, worked a lot better than Flex.
Short answer: No
Long answer: You can use Adobe's tools to compile your Flash/Flex app for use as a native iOS app. So you won't be able to embed the app in a web page like you normally could with Flex, but you can build it as a native app. Note you have to have Flash Builder 4.5 to do this.
It won't run on iPhone as a .swf file, but it will run on Android based devices that have adobe flash installed. It will also run on the BB playbook, which also has flash.
Flex is a framework.( Anyway it is very beutiful one which even sometime looks like complete different language ).
As soon as you are building AIR application it can run on various platforms like : Windows, iOS, Android, upcomming TV's, PlayBook, even .. into the future ( maybe/hopefuly ) on Windows Phone, plus Linux ( which AIR future is not very clear anyway ( but hopefuly Adobe will reconsider ) ).
So - application created with Flash Builder 4.5+ would probably run everywhere as soon as it is AIR application.
The compilation methoods is really simple, and you almost simultaneously compiling for everything you wanna to.
And one of the most important things here - your applications will run, work, look and feel the same way you were designed on one device. Flex is the thing which is responsible for everything to looks beutiful on each platform it is running.
For instance i am compiling currently for Android, and without even test i can clearly say that it will looks and feel the same way under iOS and Windows, and it will.
