C# :: Using Silverlight Or Flash To Detect USB Devices On Client Machine
Mar 29, 2012
I am using Asp.Net/C# in my application,I have a requirement where I need to access USB devices of client computer and run one of them.It is ok if the user has right to allow it or not.I need to know whether it is possible at all from browser.If yes what can be used here flash or silverlight.
I'm developing chat application. I use flash as front end and asp.net back-end. My question is: can my asp.net web app send data to flash app in browser without post back ?actually it mean asp.net push data to flash client.
Is there a reliable way to access the client machine's clipboard using Javascript? I continue to run into permissions issues when attempting to do this. How does Google Docs do this? Do they use Flash?
I need to test the upload speed of the client machine in AS 3.0. So I thought to upload an image that embed to swf, to server without user interaction.
This is my first post on this forum, i've just joined because i was pretty sure i will find all my answers here what i want is to save a movieclip as a picture so a client can dowload it to his/her machine.but it doesn't work, because i don't have jpegencoder library. i searched the net for it and i didn't find a way to download it.So, how can i get it and install it on my machine? I have flash 9 CS3, so is it already installed on my machine? and if so, how can i activate it?
i need to play back mp3 file in flash. but i have more one output device installed in my pc. the question is:- can flash list all (detects) audio output device installed in my pc then let me pick one of them to play back sound by selected output device?
I'm currently using this to detect if the visitors have flash installed or not and if not right away I'm assuming they are iPhone users but then now it seems it doesn't always work like I wish to because sometime they being redirect to the version of flash of my site and sometime the person who got flash installed also redirect to an iPhone version of my site.[code]the thing is how would I detect if they are iPhone/iPad/iPod/AppleTV something like that and redirect them to the flash=false URL and if they are non of the above will be redirect to flash=true?
I've looked at FileReferenceList and see how to get a list of files from the user's computer. This should work OK for my needs, but what I'd really like to do is have the user drag a directory from their desktop onto the app and iterate through the files. Is this possible or is FileReferenceList the best/only option?
I'm working on a project that demands a file upload for images. The guys over at development decided to use flash for this but they are not very proficient on the platform. Go figure... What I would like to do is get the image dimensions for validation purposes BEFORE the image is received by the server. I know it is possible to check for file size.
I have a django site where I'm thinking about making a rich/thick client app to allow the user to do operations that would otherwise be really difficult to otherwise. some of the requirements would be things like importing xls, csv documents being able to manipulate data from the site and/or from the imported xls in a drag and drop fashion (e.g. put a bunch of users in groups, etc)etc It seems the rich client choices out there seem to be
silverlight flex HTML5 + whatever.
and thick client
.NET Java
I'm not crazy about making a thick client because (desktop/laptop) platform independence would be nice.HTML5 would allow me to offer stuff to users on tablets i suppose,... but it's a luxury and doesn't really fit the main use case anyway.If there is a service provider out there that has a platform for doing things like this that i can just leverage, well that would be awesome too.
1. How can I get a list of available system fonts on the client machine?2. Is there any way to specify a font stack for TextFormats g. Univers, Helvetica, _sansor do I need to chack for each font's availability and alter the TextFormat accordingly?
How can the disconnection or Closure of the flash client be detected while using a php backend which ensures that only active client usernames are present in the datbase. My approaches were to use some polling method - where the client sends some message to the server periodically else the server deletes the client's name from the DB assuming it is closed - or to use some augmenting javascript code that informs the backend of a closure event.
In Flash user can give permission to localhost and even local html file to access remote webservice.I fail to see the same thing for Silverlight which is a nightmare for testing on local pc.
I have a requierement in my project that i need to store 'US/Eastern EST' and day light saving 'US/Eastern EDT' in data base if client machine is in US/Eastern time zone. Because this gives clear identification instead of justing the chars like 'EST'. There is CDT in US region as well as Chaina too so can't relay just on three chars like 'EST'/'EDT'.
i need a webpage (host on my website) that can play the following mp4 file either via silverlight 4 or flash[URL]..i tried various solution like flowplayer and silverlight but none of them work with the URL above. I can play the file fine using Windows media player or VLC.
For silverlight, i always get AG_E_NETWORK_ERROR exception within MediaFailed event. For flash, via flowplayer, IE page is just blank
Can someone tell me what am i missing? i am very frustrated as I have finished encoding, upload, cataloging my videos and now I am stuck at the last step.
I found Vectorlight which is quite good, but are there any tutorials or books about doing cool effects with silverlight. I'm after for resources focused more for a designing and presentation. Mostly the books about Silverlight is focused on doing boring business applications like making grids and forms.
I have to prepare a comparison between the following technologies to present it to my Project Manager, but I fell that I'm lost I want to compare between them in the following areas:the support of online video streaming the budget of using each one Learning Time will be needed to learn the technology Which one is the standard and will target a lot of users The support if I found any problem Bugs and security issues connection to DB, SOA and web services supporting of multi player
I am currently working on a windows phone project where i have test the compatibility and I do not know flash and Silverlight is supported or not on windows phone 7.3.
Is there any way to detect whether sound card is installed on a machine using AS 2.0? I am embedding my swf in an html (javascipt)file. If this is possible in javascript, even then it will solve my purpose.
I have a Flex application that connects to a BlazeDS server using the StreamingAMF channel. On the server-side the logic is handled by a custom adapter that extends ActionScriptAdapter and implements FlexSessionListener and FlexClientListener interfaces.
I am asking how can I detect which "flex-client" has closed a connection when for example the user is closing the browser? (so I can clean some infos inside the database)
I tried using the following:
1. To manually manage the command messages:
@Override public Object manage(final CommandMessage commandMessage) { switch (commandMessage.getOperation()) {
As it is said here: [URL] "If you do a Google search today for "MVVM and Flex", the first post is by somebody who claims that MVVM is not a good fit for Flex. I couldn't disagree more. Out of the box, the Flex framework makes it much easier to implement a Presentation Model than similar MVVM implementations in Silverlight. That is not to say that there aren't good third-party libraries that make it easier in Silverlight, but without any help, it is easier to do in Flex." So MVVM as LOGICAL CONCEPT can be implemented in both but the way it is implemented in Silverlight requires more Plumbing than Flex.
What prevents Silverlight MVVM to be implemented like Flex ? Doesn't Silverlight have same capability in event system to do the same? If yes why does Silverlight do things more complicated what's the advantages then ? Is it about using Class Interfaces which are more strongly typed? What are the disadvantages also ? For example as for implementing MULTIPLE VIEWS for 1 View-Model does Flex implementation make it also more obvious?
Am building a video chat application and i was wondering if there are any native events for the NetStream that fire,that can help in detecting when a remote client starts/stops streaming video over his outgoing stream (NetStream) to which the other client has subscribed over P2P/RTFMP in AS3 ?I maybe able to dispatch custom messages since the two clients are already connected, but i don't want to add the extra overhead.
I'm trying to make a guitar practice website, and a critical functionality is to loop over very short mp3 files (a few seconds long), with absolutely zero gap in between. For example, it could a 4-measures-long chord progression, and I want to allow the user to loop over it seamlessly.
I tried using the HTML5 <audio> tag with the loop attribute. Google Chrome gives a small gap between the loops, but big enough to be totally unacceptable for my purpose. I haven't tested the other browsers, but I believe it won't work.A possible workaround is to use ffmpeg to stream repetitions the same audio as an mp3. However, this costs a lot of bandwidth.
For myself I use Audacity to loop without gaps, but unfortunately Audacity doesn't have a web version.So, do you have any ideas how I may loop over an mp3 in a browser with zero gap? I prefer non-Flash solutions, but if nothing else works I'll use Flash.
We are on PC - CS5 Flash. We don't do very much at all in flash we try to use Java instead. But is there a way to get this to work? Can someone send instructions.
