Flex :: PDF - Check For Server Error On File Download?
Feb 7, 2011
I'd like to have Flex trigger the browser to download a PDF file from a server, but if anything goes wrong with the script that generates the file I want to be able to throw a meaningful error from Flex. Is it at all possible to try to open the URL in Flex first and check the response's HTTP status or Content-Type, then if it's a PDF file and not an error pass it up to the browser to display the "Save File..." dialog?
i try to load file from remote server and open the file with default application.
private function getRemoteCourr(PathFichier:String, FileName:String):void { urlStream = new URLStream(); fileData = new ByteArray(); var urlRemoteCourr:String = new urlManager().urlCourriersPat();
The code flow is as follows: user clicks 'download details' button on the page -> on button click handler a call to a RPC method is made using s:CallResponder -> RPC method generates and returns a URL from where to download the file -> the success event handler of the CallResponder gets the url where FileRefrence.download() is used to download the file but throws following error:-
Error: Error #2176: Certain actions, such as those that display a pop-up window, may only be invoked upon user interaction, for example by a mouse click or button press.
I want to download files from the server side to client side without prompting a window to the user to download when any updates happen at server side.Right now I am using urlstream class but first file is downloading completely rest of the files contents downloading partially.
editCode sample taken from other post. Warning: it's a huuuge chunk o'code.
Is there a way to download a file with AS3 code from a server (other than creating a text hyperlink to be clicked), or is there a way to add a file to your library and then show it in you timeline. I am specifically referring to a .pdf file.
For my flash applet I need to download two text files. Both they are in ANSI format, both have Windows line breaks.
The first one does download:
Code: var loader:URLLoader = new URLLoader() var url:URLRequest = new URLRequest("http://www.utr-online.com/IVAORealtime.txt") loader.addEventListener(Event.COMPLETE, loadcomplete)
I want my app (AIR app ported on iOS) to be able to show file located on the remote server and open it with default app (if there's one on device). Is it possible (maybe one can somehow use openWithDefaultApp here)?
UPD: I succeed with downloading (into File.documentsDirectory). I can't force iPad to open downloaded files.
UPD2: I tried to use both openWithDefaultApp and NavigateToUrl.
I've got a situation that involves error #2174. Flash 10 apparently doesn't allow more than one upload/download/load/save at a time, but my code doesn't actually do that. A skeleton:
ActionScript Code: private function uploadFile(endpoint:String):void {
Whats the best way to check if a file is on a server (the same one that the flash file is on). I need to call whatever the function maybe before using LoadMovie.
I installed said program but whenever I add users, it says they were added successfully and exist in CMD.However when I check the users.dat file it is empty. When I try Live Encoder it says the user does not exist.
I use fileReference.download() to download files. The fileReference send request to java servlet.In servlet, some error may be checked. For example error - 'File not found'. I want to send the error to flex side. I tried lots of methods,but fileReference in flex can't receive them.Such asresponse.sendError(HttpServletResponse.SC_NOT_FOUND, "File not found");r PrintWriter out = resp.getWriter(); out.print("File not found");It seems fileReference can't triggers event 'DataEvent.UPLOAD_COMPLETE_DATA' and'HTTPStatusEvent.HTTP_STATUS'.
I'm using Flash CS5 on Windows 7. I was working on a file and went to save (CTRL+S) and the Save dialog locked up and Windows gave me an error that said "Flash has stopped working. Close Program" So I did and restarted Flash. When I tried to open the file I was working on, Flash said "Unexpected File Format" The file size of the SWF is right, it's not 0kb or anything. This is about 3 weeks worth of work on here. I'm checking the backup tape for our company server, but that will still set me back about half a day (which is better than nothing I suppose)
So I basically have used the fileReference class to allow the user to download a determined file if he wants to.
I use the file.download(URL) function and it works well.
However, the file is downloaded and saved to the hard drive using only the flash player. The browser is not aware of the download, and thus, if I want to show the progress of the download I'd have to make some progress bar myself. I know how to do it, but it would become really tedious and take too much UI space.
Isn't there a damn way in Flash to "send" a determined file to the browser so that it prompts the user to download it? It's an image file, so navigateToURL doesn't cut it since it will just display the image, both if I use a new tab or the current one.
private function downloadPDF():void { var httpService:HTTPService = new HTTPService(); httpService.url = "http://coenraets.org/flexandroid90/FlexAndroid90Minutes.pdf";
Is it possible download a file in an AIR application, store it on the user's system, and prohibit access to the files by applications other than the one with which it was downloaded?
I want to analyse if the XML I send from my client Flex to my Java using remoteObject is compressed or not. for this, I'm using Wireshark, but it can't get packets in the localhost (windows vista)
I'm getting an anoying problem in IE6.02 when trying to download a file through flex + struts action, the browser opens a new window and doesn't close it after the download has finished.
The flex code is: navigateToURL(url,"_blank"); The content headers are: HTTP/1.x 200 OK Date: Thu, 29 Oct 2009 22:00:44 GMT Transfer-Encoding: chunked Content-Type: application-download; charset=UTF-8 Content-Disposition: attachment; filename=myfile.pdf X-Powered-By: Servlet/2.4 JSP/2.0
Also, we tried with Content-Type: application/pdf; charset=UTF-8 How do I close the new opened window automatically? In FF works perfectly.
My Flex client app has got some data from the back end (RemoteObjects, BlazeDS, Spring). Client has got all the data it needs, it now needs to put some information in a CSV format and make it available for download.Using Flex 3 for this.
I am building an Adobe Air Mobile application currently targeting Android (and eventually iOS). I'm using Flash Builder 4.6 (which is Flex).I have a requirement to download a zip file from a url, save it to local storage and unzip the contents.There seem to be a few example on how to do a download in Flex/Air, but not many in Flex/Air/Mobile. Additionally, the mix of examples seem to be all over the place with namespace versions, etc. Edit: What I've tried:So, from the examples on the web, the first thing I did was add namespace in Flex declarations: xmlns:net="flash.net.*" Then I added the following component: <net:URLLoader id="urlLoader" /> Then, in the button click event, I called it: urlLoader.load(new URLRequest(downloadUrl)); I get a run time error: Error #2044: Unhandled ioError:. text=Error #2032: Stream Error. URL: http://...
Can anyone offer any insight into how to check if a file is newer and then down load MC/swfs from external connection (i.e. website) for use with projectors, or in that case swf? I know it's possible with Swf Studio or the like, just wondering if it's poss with flash alone.
