• Programmatically determining the status of a file download

  - by Tim

  Is there a way I can programmatically determine the status of a download in Chrome or Mozilla Firefox? I would like to know if the download was aborted or completed successfully. For writing the code I'd be using either Perl, PHP or Python. Please help. Thank You.

• CMD file time not always matching windows explorer file time

  - by skyrail

  I have a set of file I need to set the created, modified and last access date to exif date taken value, after a copy between 2 folders (might be fat32 on memory card or ntfs on fixed or usb disk). When I copy a file, the date and time switch to the current date. Then I change all 3 dates manually, either with change attributes in windows explorer or far manager on the command line. To make it faster I wrote a batch script getting original file dates (with php and function stat), building a batch script that invoke nircmd setfiletime for each file. Then I apply this batch to the copied version. The operation is relatively fast and reliable. Unfortunately, a bunch of files have last access and created time different in cmd and windows explorer (1H difference). Very strangely, it happens with dates between november and february, which make the operation unreliable. Why is this happening, and how can I fix it?

• Outlook 2010 + Move IMAP PST file = Outlook data file cannot be accessed

  - by GWB

  I set up a new IMAP account in Outlook 2010. It works but creates IMAP PST file in C:\Users\User\AppData\Local\Microsoft\Outlook. I want the file on my data drive in D:\Users\User\Documents\Outlook Files (the same folder where outlook automatically creates the local Outlook PST. I followed the instructions here to move the IMAP PST. Testing the account (send/receive) works fine, but if I try to manually send an email I get error 0x8004010F Outlook data file cannot be accessed. I've tried repairing the PST using SCANPST (it always finds errors), and deleting and recreating the account but I get the same error. If I move the PST file back, it works again, but this is not ideal. Note: I don't think this is a duplicate of this question as the cause is different and the solution does not help.

• How to estimate download time remaining (accurately)?

  - by Mark

  Sure you could divide the remaining file size by the current download speed, but if your download speed fluctuates (and it will), this doesn't produce a very nice result. What's a better algorithm for producing smoother countdowns?

• Automatically download files in Ruby

  - by Obinna

  I'm trying to write a ruby script which automatically downloads some files from some server ever 30-45 minutes (to prevent overload) as long as my computer is turned on. It's possible that my computer might be turned off at some point, but the download should resume (probably re-download the current file). I already have the file list but I can't figure out how to make such a script to run autonomously. What are some ways I can do this?

• close file with fopen() but file still in use

  - by Marco

  Hi all, I've got a problem with deleting/overwriting a file using my program which is also being used(read) by my program. The problem seems to be that because of the fact my program is reading data from the file (output.txt) it puts the file in a 'in use' state which makes it impossible to delete or overwrite the file. I don't understand why the file stays 'in use' because I close the file after use with fclose(); this is my code: bool bBool = true while(bBool){ //Run myprogram.exe tot generate (a new) output.txt //Create file pointer and open file FILE* pInputFile = NULL; pInputFile = fopen("output.txt", "r"); // //then I do some reading using fscanf() // //And when I'm done reading I close the file using fclose() fclose(pInputFile); //The next step is deleting the output.txt if( remove( "output.txt" ) == -1 ){ //ERROR }else{ //Succesfull } } I use fclose() to close the file but the file remains in use by my program until my program is totally shut down. What is the solution to free the file so it can be deleted/overwrited? In reality my code isn't a loop without an end ; ) Thanks in advance! Marco

• How to download a file from a UNC mapped share via IIS and ASP

  - by helgeg

  I am writing an ASP application that will serve files to clients through the browser. The files are located on a file server that is available from the machine IIS is running on via a UNC path (\server\some\path). I want to use something like the code below to serve the file. Serving files that are local to the machine IIS is running on is working well with this method, my trouble is being able to serve files from the UNC mapped share: //Set the appropriate ContentType. Response.ContentType = "Application/pdf"; //Get the physical path to the file. string FilePath = MapPath("acrobat.pdf"); //Write the file directly to the HTTP content output stream. Response.WriteFile(FilePath); Response.End(); My question is how I can specify a UNC path for the file name. Also, to access the file share I need to connect with a specific username/password. I would appreciate some pointers on how I can achieve this (either using the approach above or by other means).

• forcing a download using PHP / jQuery

  - by Dirty-flow

  I know there are already many questions about forcing a download with PHP, but I can't find what I'm doing wrong and what should I do. I'm having an list with filenames, and I want to download one of them by clicking a button. My jQuery: $(".MappeDownload").on("click",function(e){ e.stopPropagation(); fileId=$(this).val() $.post("ajax/DownloadFile.php",{ id : fileId}) }) and on the server side I have a table with the file names and the file path. $sql = "SELECT vUploadPfad, vUploadOriginname FROM tabUpload WHERE zUploadId='$_POST[id]'"; $result = mysql_query($sql) or die(""); $file = mysql_fetch_array($result); $localfile = $file["vUploadPfad"]; $name=$file["vUploadOriginname"]; $fp = fopen($localfile, 'rb'); header("Cache-Control: "); header("Pragma: "); header("Content-Type: application/octet-stream"); header("Content-Length: " . filesize($localfile)); header("Content-Disposition: attachment; filename='".$name."';"); header("Content-Transfer-Encoding: binary\n"); fpassthru($fp); exit; The AJAX request is successful, I'm getting the right header(filesize, filename etc...) but the download are not starting.

• PHP download page: file_exists() returns true, but browser returns 'page not found'

  - by Chris

  I'm using PHP for a file download page. Here's a snippet of the problem code: if (file_exists($attachment_location)) { header($_SERVER["SERVER_PROTOCOL"] . " 200 OK"); header("Cache-Control: public"); // needed for i.e. header("Content-Type: application/zip"); header("Content-Transfer-Encoding: Binary"); header("Content-Length:".filesize($attachment_location)); header("Content-Disposition: attachment; filename=file.zip"); readfile($attachment_location); die("Hooray"); } else { die("Error: File not found."); } This code works absolutely fine when testing locally, but after deploying to the live server the browser returns a 'Page not found' error. I thought it might be an .htaccess issue, but all .htaccess files on the live server are identical to their local counterparts. My next guess would be the live server's PHP configuration, but I have no idea what PHP setting might cause this behaviour. The file_exists() function always returns true - I've checked this on the live server and it's always correctly picking up the file, its size etc., so it does have a handle on the file. It just won't perform the download! The main site is a Wordpress site, but this code isn't part of a Wordpress page - it's in a standalone directory within the site root. UPDATE: is_file() and is_readable() are both returning true for the file, so that's not the problem. The specific line that is causing the problem is: readfile($attachment_location) Everything up until that point is super happy.

• Android: writing a file to sdcard

  - by Sumit M Asok

  I'm trying to write a file from an Http post reply to a file on the sdcard. Everything works fine until the byte array of data is retrieved. I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest and tried many different combinations of tutorials I found on the net. All I could find was using the openFileOutput("",MODE_WORLD_READABLE) method, of the activity but how my app writes file is by using a thread. Specifically, a thread is invoked from another thread when a file has to be written, so giving an activity object didn't work even though I tried it. The app has come a long way and I cannot change how the app is currently written. Please, someone help me? CODE: File file = new File(bgdmanip.savLocation); FileOutputStream filecon = null; filecon = new FileOutputStream(file); // bgdmanip.savLocation holds the whole files path byte[] myByte; myByte = Base64Coder.decode(seReply); Log.d("myBytes", String.valueOf(myByte)); bos.write(myByte); filecon.write(myByte); myvals = x * 11024; seReply is a string reply from HttpPost response. the second set of code is looped with reference to x. the file is created but remains 0 bytes

• AS3 Working With Arbitrarily Large Files

  - by Kekoa

  I am trying to read a very large file in AS3 and am having problems with the runtime just crashing on me. I'm currently using a FileStream to open the file asynchronously. This does not work(crashes without an Exception) for files bigger than about 300MB. _fileStream = new FileStream(); _fileStream.addEventListener(IOErrorEvent.IO_ERROR, loadError); _fileStream.addEventListener(Event.COMPLETE, loadComplete); _fileStream.openAsync(myFile, FileMode.READ); In looking at the documentation, it sounds like the FileStream class still tries to read in the entire file to memory(which is bad for large files). Is there a more suitable class to use for reading large files? I really would like something like a buffered FileStream class that only loads the bytes from the files that are going to be read next. I'm expecting that I may need to write a class that does this for me, but then I would need to read only a piece of a file at a time. I'm assuming that I can do this by setting the position and readAhead properties of the FileStream to read a chunk out of a file at a time. I would love to save some time if there is a class like this that already exists. Is there a good way to process large files in AS3, without loading entire contents into memory?

• Download YouTube Videos the Easy Way

  - by Trevor Bekolay

  You can’t be online all the time, and despite the majority of YouTube videos being nut-shots and Lady Gaga parodies, there is a lot of great content that you might want to download and watch offline. There are some programs and browser extensions to do this, but we’ve found that the easiest and quickest method is a bookmarklet that was originally posted on the Google Operating System blog (it’s since been removed). It will let you download standard quality and high-definition movies as MP4 files. Also, because it’s a bookmarklet, it will work on any modern web browser, and on any operating system! Installing the bookmarket is easy – just drag and drop the Get YouTube video link below to the bookmarks bar of your browser of choice. If you’ve hidden the bookmark bar, in most browsers you can right-click on the link and save it to your bookmarks. Get YouTube video   With the bookmarklet available in your browser, go to the YouTube video that you’d like to download. Click on the Get YouTube video link in your bookmarks bar, or in the bookmarks menu, wherever you saved it earlier. You will notice some new links appear below the description of the video. If you download the standard definition file, it will save as “video.mp4” by default. However, if you download the high definition file, it will save with the same name as the title of the video. There are many methods of downloading YouTube videos…but we think this is the easiest and quickest method. You don’t have to install anything or use up resources, but you can still get a link to download an MP4 with one click. Do you use a different method to download Youtube videos? Let us know about it in the comments! javascript:(function(){if(document.getElementById(’download-youtube-video’))return;var args=null,video_title=null,video_id=null,video_hash=null;var download_code=new Array();var fmt_labels={‘18′:’standard%20MP4′,’22′:’HD%20720p’,'37′:’HD%201080p’};try{args=yt.getConfig(’SWF_ARGS’);video_title=yt.getConfig(’VIDEO_TITLE’)}catch(e){}if(args){var fmt_url_map=unescape(args['fmt_url_map']);if(fmt_url_map==”)return;video_id=args['video_id'];video_hash=args['t'];video_title=video_title.replace(/[%22\'\?\\\/\:\*%3C%3E]/g,”);var fmt=new Array();var formats=fmt_url_map.split(’,');var format;for(var i=0;i%3Cformats.length;i++){var format_elems=formats[i].split(’|');fmt[format_elems[0]]=unescape(format_elems[1])}for(format in fmt_labels){if(fmt[format]!=null){download_code.push(’%3Ca%20href=\”+(fmt[format]+’&title=’+video_title)+’\'%3E’+fmt_labels[format]+’%3C/a%3E’)}elseif(format==’18′){download_code.push(’%3Ca%20href=\’http://www.youtube.com/get_video?fmt=18&video_id=’+video_id+’&t=’+video_hash+’\'%3E’+fmt_labels[format]+’%3C/a%3E’)}}}if(video_id==null||video_hash==null)return;var div_embed=document.getElementById(’watch-embed-div’);if(div_embed){var div_download=document.createElement(’div’);div_download.innerHTML=’%3Cbr%20/%3E%3Cspan%20id=\’download-youtube-video\’%3EDownload:%20′+download_code.join(’%20|%20′)+’%3C/span%3E’;div_embed.appendChild(div_download)}})() Similar Articles Productive Geek Tips Watch YouTube Videos in Cinema Style in FirefoxDownload YouTube Videos with Cheetah YouTube DownloaderStop YouTube Videos from Automatically Playing in FirefoxImprove YouTube Video Viewing in Google ChromeConvert YouTube Videos to MP3 with YouTube Downloader TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 PCmover Professional 15 Great Illustrations by Chow Hon Lam Easily Sync Files & Folders with Friends & Family Amazon Free Kindle for PC Download Stretch popurls.com with a Stylish Script (Firefox) OldTvShows.org – Find episodes of Hitchcock, Soaps, Game Shows and more Download Microsoft Office Help tab

• PHP file_put_contents File Locking

  - by hozza

  The Senario: You have a file with a string (average sentence worth) on each line. For arguments sake lets say this file is 1Mb in size (thousands of lines). You have a script that reads the file, changes some of the strings within the document (not just appending but also removing and modifying some lines) and then overwrites all the data with the new data. The Questions: Does 'the server' PHP, OS or httpd etc. already have systems in place to stop issues like this (reading/writing half way through a write)? i. If it does, please explain how it works and give examples or links to relevant documentation. ii. If not, are there things I can enable or set-up, such as locking a file until a write is completed and making all other reads and/or writes fail until the previous script has finished writing? My Assumptions and Other Information: The server in question is running PHP and Apache or Lighttpd. If the script is called by one user and is halfway through writing to the file and another user reads the file at that exact moment. The user who reads it will not get the full document, as it hasn't been written yet. (If this assumption is wrong please correct me) I'm only concerned with PHP writing and reading to a text file, and in particular, the functions "fopen"/"fwrite" and mainly "file_put_contents". I have looked at the "file_put_contents" documentation but have not found the level of detail or a good explanation of what the "LOCK_EX" flag is or does. The senario is an EXAMPLE of a worst case senario where I would assume these issues are more likely to occur, due to the large size of the file and the way the data is edited. I want to learn more about these issues and don't want or need answers or comments such as "use mysql" or "why are you doing that" because I'm not doing that, I just want to learn about file read/writing with PHP and don't seem to be looking in the right places/documentation and yes I understand PHP is not the perfect language for working with files in this way...

• How to download media content on demand and reuse from browser cache in silverlight

  - by Andrew

  Hi. I have a problem with simple silverlight app, this app has a couple of buttons, each button sets mediaelement source to a short mp3 file and plays it, my problem is that when i press the same button second time it re-downloads mp3 file again but i think it shouldn't, instead it should use a copy of browser cached mp3 file that was downloaded when a button was pressed for the first time. I'm using sl4 and links in mediaelement are just simple uri's, i need to make it working in this way that when some mp3 was downloaded it will be cached on the client browser and further click on button will use a cached version of file instead of downloading it again and wasting my bandwidth. Any ideas ?

• ASP.NET Grid AjaxPanel Download Issue

  - by Mahesh

  Hi, I have a telerik grid which is performing operations like searching,sorting,filtering etc. To make customers happy, we put this control in an ajax panel for seamless experience. Now, we added a new functionality to the grid where the customer can download the entire row information as a csv file. As the response is a file, ajax panel is trying to parse the output and throwing the following exception: Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near '?'. Could you please help me in having both functionalities( Ajax and Download) in place without any error?? Thanks, Mahesh

• Computing MD5SUM of large files in C#

  I am using following code to compute MD5SUM of a file - byte[] b = System.IO.File.ReadAllBytes(file); string sum = BitConverter.ToString(new MD5CryptoServiceProvider().ComputeHash(b)); This works fine normally, but if I encounter a large file (~1GB) - e.g. an iso image or a DVD VOB file - I get an Out of Memory exception. Though, I am able to compute the MD5SUM in cygwin for the same file in about 10secs. Please suggest how can I get this to work for big files in my program. Thanks
