Silverlight :: Automated File Upload From Browser?
Aug 13, 2010
After all what I've read on this topic, I know that there is no way to do automated file upload from browser without some kind of "elevated permissions".But, elevated permissions is something what I have, bacause the application runs on intranet and user currently enables access to ActiveX control that makes it possible to do some document scanning using COM. Then a scanned document saved on file system needs to be uploaded.Now, the only browser requirement is IE7+ compatibility. But with IE8, the only way to set value to <input type="file" ... /> is manually clicking "browse" button.
Is there really no way to set value to input form field, even if the site is added to trusted sites and full access for ActiveX code is enabled?The same seems to apply to Flash and Silverlight, security policy makes it impossible to upload file without user manually selecting it. Silverlight probably could do it in OOB mode, but that is way toointerruptive if a user has to click to enable out of browser mode every time.ActiveX and Java applet could probably do it. If using <input type="file" ... /> is not an option, is there any lightweight (possibly free/open-source) ActiveX control that would handle uploading from file system?
updateI did investigated all the options quite in depth back there, and it turned out it's the paradigm of security model which makes it impossible to do automated file upload from the browser without user interaction. That means the use must either manually interact to upload file or confirm some ActiveX control or similar plugin to do that job. If you manage to find a way to upload without some special plugin with elevated permissions, you probably found a security hole, which will be fixed soon. However, that's the way web brower technologies are designed to work.
I'm looking for options on uploading really big files (over 2Gb) using web browsers. I know that Java applet solutions will work, I know (and have tested by myself) that Flash has internal limitation about 2Gb. What about Silverlight?
I am developing a project in which I am required to open an exe file (i.e. notepad) right inside the browsers window. The solution can be in any programming tool / language. I have tried a sample program in VB.NET and it is working. (see the figure attached below)
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.
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 created a silverlight application , but i need to embed it to a Flash file(swf) which it runs with Flash Player ( whithout using browser), I had found a solutions to call it using javascript, but it still needs my flash file run inside the browser, dose any one can help me, Either to run js inside swf (without need of browser) or any other way that i can embed my Silverlight application inside Flash.
I have an HTML form with a file upload element, which is based on Uploadify. Unfortunately, if the browser doesn't have flash installed/enabled (I tested on Chrome and Safari), then the file upload element is completely disappearing, while I would have expected to have at least plain, regular, file upload html element as a fallback.
You can see this behavior even in Uploadify official demo (as of today, 28.2.2011):
none of these work in the situation that flash is installed, but is disabled ! for example, this line:
if (swfobject.getFlashPlayerVersion().major === 0)
behaves the same weather flash is installed and enabled, or installed and disabled I thought about obtaining uploadify API and checking it, but I have found zero examples
Ok so from all my research I'm fairly positive P2P is not possible in Silverlight 4 (in browser). Flash can do P2P using Stratus/RTMFP which I believe uses UDP hole punching and a Stratus server to initialize the connection. Is there any plans for Microsoft to add some kind of p2p rendezvous service in the future? Can we get a definitive yes/no on whether or not p2p is possible in SL4.
For an internal project we would like to play with building a video conferencing system.We are able to decide the browser that the user has to use and can install plugins. The only requirement is that the browser and plugins must be free and work over Linux and Mac.(Don't care about Windows)What is the best way to do access the webcam and mic stream from a user for sending to a server? Ideally I would like to do this plugin free but I can see no implementation of the devices tag in HTML5 in any browser yet, unless someone knows different.If its flash/silverlight, any quick examples of capture and sending to a server?lso any examples of streaming video from a server to a client would be useful, so we can stick it all together. This I know we can do in HTML5 so this would be a preference.
The client connection part is all I would need as we are building the server, this is the internal challenge.Basically I'm looking for good examples and best practices for sending and receiving this information.Edit: As I have discovered from some groups the device tag is no where near completion. So answers will have to be flash/silverlight (does that work on linux??).
I'm making an application with SL/flash charts and am wondering if there is a way to test if the browser it's being pushed to supports silverlight or not (ipad/iphone). And if it doesn't, then I can use some kind of AJAX chart in its place.If this is possible to interchange platforms by testing against the host, how would I do this?
I'm doing a AS3 project in Eclipse and trace alot of values. I though it would be nice to have a toString() function in every class, at the bottom of each class as the last function, but i dont want to do this by hand for 500+ files. Is there a quick and good way of doing this automated?
It works by reading an existing Class file, parses it, generates an Interface-like .as file for it, and saves it locally, all from within FlexBuilder. It works perfectly but I'd like to improve it by having it automatically open, modify and save the files with only a few user clicks required.Currently I'm using FileFilter, but this requires that the programmer manualy select each file to parse, and then manually select where to save the output - it's tedious.Normally I'd simply use AIR, but because of my company's security policies I am not allowed to create my own AIR applications.
my listener.onComplete = function(selectedFile:FileReference) is fired without any file in the upload dir. if the file is small and I wait a bit I can see the file (through FTP) coming up on the server, but most of the times the "onComplete" if fired without any file being saved.
can I add something to this php code to make sure the file is uploaded?
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.
I needed a file upload feature. I pretty much just copy pasted the code from the flash help and when rendering, flash would show the file browser window when rendered in flash.However, when displaying the swf in the browser, either on my local laptop server or FTP-ed up on my server, the popup would not pop(up).why does it run when publish/test it in flash?
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?
Is there any "mainstream" library used for this purpose? Commonly spread, well maintained, documented etc.I found these (using flash):
Uploadify - not many releases, latest 12/2010, no documentation (!) SWFUpload - latest release 03/2010, documentation fancyupload - looks buggy.
phpfileuploader - looks heavyweight, and looks commercial (?) I cannot read the licence (you can download it but are you allowed to use it forever without paying?) plupload New version of pure javascript (no flash) Valums' ajax upload claims to handle file size limit and progress bar, which is quite suspicious to me: these features require to guess the file size before the upload, which seems impossible in javascript (look also here). Or can it work?
I am trying to upload a file on server using File class. Its working fine on local machine. But when i a placing the php file on server, it is giving Error #2038: File I/O Error.
I want to upload directly to an S3 bucket.I know this can be done in AIR,whether it is actually possible in flex in the browser, or will I have to use some code server side to get this going?
I'm actually an artist who happened to stumble on flash and have been subsidizing my income with animation projects for some time.My question, query, bane of my existence is the automation of my e-cards.Many many people ask how they can send my cards. Up to now I have been manually customizing cards. whew.I would like to make the .swf files fully automated so people can fill out the "to, from, text message" and e-mail a notice to a customized animation.Is there a generic code I can cut and paste? Beyond basic html code,(seen on my site)
When using HTML and CSS you can automate the size of an "area" of the page an "area" is classed as a DIV and you automate it by setting its height and/or width to auto (usually height only with width given a fixed size)in adition you can set the DIVs overflow parameter
this is vital for CMS managed websites
does flash have any simple functions for achieveing the same result? or if i used flash with a CMS system would i need use AS3 to calculate the total height and width of all child objects and set this number as the height and width of the pearent object? (with HTML/CSS i would use javascript to do this)
I have searched everwhere on the internet for a solution, with no luck, so I am hoping that someone can point me in the right direction.I am trying to make a kind of interactive tv. I have eight scenes and each scene has four choices of movie clips.A user picks one clip from each scene, maybe with check boxes. This generates a playlist which is loaded into a flv player which in turn plays the eight clips in order.
