  • Questions related to writing your own file downloader using multiple threads java

    - by Shekhar
    Hello In my current company, i am doing a PoC on how we can write a file downloader utility. We have to use socket programming(TCP/IP) for downloading the files. One of the requirements of the client is that a file(which will be large in size) should be transfered in chunks for example if we have a file of 5Mb size then we can have 5 threads which transfer 1 Mb each. I have written a small application which downloads a file. You can download the eclipe project from http://www.fileflyer.com/view/QM1JSC0 A brief explanation of my classes FileSender.java This class provides the bytes of file. It has a method called sendBytesOfFile(long start,long end, long sequenceNo) which gives the number of bytes. import java.io.File; import java.io.IOException; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileSender { private static final String FILE_NAME = "C:\\shared\\test.pdf"; public ByteArrayWrapper sendBytesOfFile(long start,long end, long sequenceNo){ try { File file = new File(FILE_NAME); byte[] fileBytes = FileUtils.readFileToByteArray(file); System.out.println("Size of file is " +fileBytes.length); System.out.println(); System.out.println("Start "+start +" end "+end); byte[] bytes = getByteArray(fileBytes, start, end); ByteArrayWrapper wrapper = new ByteArrayWrapper(bytes, sequenceNo); return wrapper; } catch (IOException e) { throw new RuntimeException(e); } } private byte[] getByteArray(byte[] bytes, long start, long end){ long arrayLength = end-start; System.out.println("Start : "+start +" end : "+end + " Arraylength : "+arrayLength +" length of source array : "+bytes.length); byte[] arr = new byte[(int)arrayLength]; for(int i = (int)start, j =0; i < end;i++,j++){ arr[j] = bytes[i]; } return arr; } public static long fileSize(){ File file = new File(FILE_NAME); return file.length(); } } Second Class is FileReceiver.java - This class receives the file. Small Explanation what this file does This class finds the size of the file to be fetched from Sender Depending upon the size of the file it finds the start and end position till the bytes needs to be read. It starts n number of threads giving each thread start,end, sequence number and a list which all the threads share. Each thread reads the number of bytes and creates a ByteArrayWrapper. ByteArrayWrapper objects are added to the list Then i have while loop which basically make sure that all threads have done their work finally it sorts the list based on the sequence number. then the bytes are joined, and a complete byte array is formed which is converted to a file. Code of File Receiver package com.filedownloader; import java.io.File; import java.io.IOException; import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.List; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileReceiver { public static void main(String[] args) { FileReceiver receiver = new FileReceiver(); receiver.receiveFile(); } public void receiveFile(){ long startTime = System.currentTimeMillis(); long numberOfThreads = 10; long filesize = FileSender.fileSize(); System.out.println("File size received "+filesize); long start = filesize/numberOfThreads; List<ByteArrayWrapper> list = new ArrayList<ByteArrayWrapper>(); for(long threadCount =0; threadCount<numberOfThreads ;threadCount++){ FileDownloaderTask task = new FileDownloaderTask(threadCount*start,(threadCount+1)*start,threadCount,list); new Thread(task).start(); } while(list.size() != numberOfThreads){ // this is done so that all the threads should complete their work before processing further. //System.out.println("Waiting for threads to complete. List size "+list.size()); } if(list.size() == numberOfThreads){ System.out.println("All bytes received "+list); Collections.sort(list, new Comparator<ByteArrayWrapper>() { @Override public int compare(ByteArrayWrapper o1, ByteArrayWrapper o2) { long sequence1 = o1.getSequence(); long sequence2 = o2.getSequence(); if(sequence1 < sequence2){ return -1; }else if(sequence1 > sequence2){ return 1; } else{ return 0; } } }); byte[] totalBytes = list.get(0).getBytes(); byte[] firstArr = null; byte[] secondArr = null; for(int i = 1;i<list.size();i++){ firstArr = totalBytes; secondArr = list.get(i).getBytes(); totalBytes = concat(firstArr, secondArr); } System.out.println(totalBytes.length); convertToFile(totalBytes,"c:\\tmp\\test.pdf"); long endTime = System.currentTimeMillis(); System.out.println("Total time taken with "+numberOfThreads +" threads is "+(endTime-startTime)+" ms" ); } } private byte[] concat(byte[] A, byte[] B) { byte[] C= new byte[A.length+B.length]; System.arraycopy(A, 0, C, 0, A.length); System.arraycopy(B, 0, C, A.length, B.length); return C; } private void convertToFile(byte[] totalBytes,String name) { try { FileUtils.writeByteArrayToFile(new File(name), totalBytes); } catch (IOException e) { throw new RuntimeException(e); } } } Code of ByteArrayWrapper package com.filedownloader; import java.io.Serializable; public class ByteArrayWrapper implements Serializable{ private static final long serialVersionUID = 3499562855188457886L; private byte[] bytes; private long sequence; public ByteArrayWrapper(byte[] bytes, long sequenceNo) { this.bytes = bytes; this.sequence = sequenceNo; } public byte[] getBytes() { return bytes; } public long getSequence() { return sequence; } } Code of FileDownloaderTask import java.util.List; public class FileDownloaderTask implements Runnable { private List<ByteArrayWrapper> list; private long start; private long end; private long sequenceNo; public FileDownloaderTask(long start,long end,long sequenceNo,List<ByteArrayWrapper> list) { this.list = list; this.start = start; this.end = end; this.sequenceNo = sequenceNo; } @Override public void run() { ByteArrayWrapper wrapper = new FileSender().sendBytesOfFile(start, end, sequenceNo); list.add(wrapper); } } Questions related to this code 1) Does file downloading becomes fast when multiple threads is used? In this code i am not able to see the benefit. 2) How should i decide how many threads should i create ? 3) Are their any opensource libraries which does that 4) The file which file receiver receives is valid and not corrupted but checksum (i used FileUtils of common-io) does not match. Whats the problem? 5) This code gives out of memory when used with large file(above 100 Mb) i.e. because byte array which is created. How can i avoid? I know this is a very bad code but i have to write this in one day -:). Please suggest any other good way to do this? Thanks Shekhar

  • Making libmagic/file detect .docx files

    - by Jonatan Littke
    As seen elsewhere, docx, xlsx and pttx are ZIPs. When uploading them to my web application, file (via libmagic andpython-magic) detects them as being ZIP. I store the contents of the file as a blob in the database, but naturally I don't want to trust the user with what kind of file type this is. So I would like to trust file for and automatically generate a filename during download. I know one can modify /etc/magic but the format (magic(5)) is way too complicated for me. I found a bug report on the issue at Debian bugs but since it's from 2008 it doesn't seem to be fixed any time soon. I guess my only other alternative is to indeed trust the user (but still store the contents as a blob) and only check the file extension based on the file name. This way I can disallow some extensions and allow others. And when the user re-downloads his file, he can have it in whatever way he uploaded it. But this solution is insecure if the file is shared with others, since you can simply rename the file to allow uploading it. Any ideas? Lastly, I found a list of magic numbers for docx etc, but I'm unable to convert these into the magic(5) format.

  • Running batch file through a service.

    - by wallz
    I'm trying to schedule a batch file to run through a third party application, however the output file doesn't get created in the directory. If I run the .BAT file from the command line, it works and the file gets created. Also using the Windows Schedule will also succeed. Basically, the 3rd party software will schedule the .BAT file and it shows success within the 3rd party user interface. The difference between running from the command prompt and the software, is that the software will use its Windows service to launch the batch. The 3rd party software will show success since it was able to successfully call the .BAT file to run, however it has no control of the other EXE's that's being called within the script. I'm able to run a simple .BAT file in the 3rd party software, for example a copy command. The .BAT I'm having problems with calls a compiled EXE which launches Excel to create a file to a location. The .bat file calls something.exe, which then calls Excel.exe: C:\something.exe -o D:\filename.xlsm C:\filename.xlsm refresh_pivot Do you think it's a permissions issue? I used Process Monitor to verify any Access Denied errors but everything seems to be working according to the trace. It worked on a non-64-bit OS, I'm currently using Win2008 64-bit.

  • How to make Firefox file associations consistent with Ubuntu file associations?

    - by wbharding
    This seems to be a pretty commonly Google question, but one for which there are no answers. http://www.linuxquestions.org/questions/linux-software-2/firefox-download-mime-types-378902 http://www.birkit.com/content/kubuntu-linux/internet/firefox/fix-file-associations-in-firefox.html Being three links amongst the many. The gist of what I want to accomplish is to have Firefox understand the file associations I download without me having to manually map all of them myself. Gnome knows the file extensions, so I would have expected that Firefox could just use the already-known file mappings there to open the right stuff (as I presume Chrome does). But it doesn't. At least not for me, using Firefox 4, and not by default. When I click on a downloaded file right now, Firefox always has to ask me what application should be used to open the file. A handful of Google results tell me that I can reassociate my file extensions by deleting ~/.mozilla/firefox/[profile name]/mimeTypes.rdf, but while deleting that file does in fact result in a new mimeTypes file being generated, the new mimeTypes is just as barren as the old one had been. Based on the amount of unanswered Qs on the Googlesphere, I know this is a very common problem for Ubuntu users, but it seems to be one for which nobody has chimed in with a good solution. Maybe Superuser can finally be the panacea for us all?

  • I am trying to zip files individually, but the file type is unknown

    - by Jason Mander
    I am trying to zip some files with an unknown file type individually. I am using the following code in a batch script to do that: @ECHO OFF FOR %%A IN (bestbuy*nat*component.cpi*) DO "C:\Program Files\7-Zip\7z.exe" a -mx9 -m0=lzma2:d256m "%%~nA.7z" "%%A" The code will compress files individually ONLY if the file has an extension. Unfortunately the files that I have don't have any extension. In the code I am trying to zip files by doing a pattern match, the files are getting compressed into ONE file (which I do not want, I want each file compressed individually). Why does this code create separate zip files when the files have an extension (for example if I add .txt to the end of the files) and when there is no extension the code creates one zipped file. Can anyone please help me with the code to compress files with unknown file type so that each file gets compressed individually Your help would be greatly appreciated. Jason

  • Ubuntu and Windows 8 shared partition gets corrupted

    - by Bruno-P
    I have a dual boot (Ubuntu 12.04 and Windows 8) system. Both systems have access to an NTFS "DATA" partition which contains all my images, documents, music and some application data like Chrome and Thunderbird Profiles which used by both OS. Everything was working fine in my Dual boot Ubuntu/Windows 7, but after updating to Windows 8 I am having a lot of troubles. First, sometimes, I add some files from Ubuntu into my DATA partition but they don't show up in Windows. Sometimes, I can't even use the DATA partition from Windows. When I try to save a file it gives an error "The directory or file is corrupted or unreadable". I need to run checkdisk to fix it but after some time, same error appears. Before upgrading to Windows 8 I also installed a new hard drive and copied the old data using clonezilla (full disk clone). Here is the log of my last chkdisk: Chkdsk was executed in read/write mode. Checking file system on D: Volume dismounted. All opened handles to this volume are now invalid. Volume label is DATA. CHKDSK is verifying files (stage 1 of 3)...

  • Zero sized tar.gz file found inside a tar.gz file

    - by PavanM
    My current directory contains a single file like this- $ls -l -rw-r--r-- 1 root staff 8 May 28 09:10 pavan Now, I want to tar and gzip this file like $tar -cvf - * 2>/dev/null |gzip -vf9 > pavan.tar.gz 2>/dev/null (I am aware I am creating the zipped file in the same directory as the original file) When I run the above tar/gzip commands around 20 times, a few times I observe that the final tarred and zipped file pavan.tar.gz file has a ZERO sized pavan.tar.gz file. I am not sure from where is this zero sized file coming into the archive from. Note: I am NOT running tar/gzip commands on an already existing tar.gz file. I always make sure that the directory has only one file before running the commands On googling, as described here, I suspected that the tar.gz being created was also part of the file being archived. But in my case, gzip is the one who's creating the final file and by the time gzip runs, tar should be done tarring. This is happening on AIX but I've used Linux tag too, to draw more attention, as I guess the problem is platform independent.

    I was using windows 7 till yesterday. I tried to install ubuntu 14. 04 Lts version yesterday with in windows 7. But it was not succeeded. Then I decided to install ubuntu only. By mistake I installed ubuntu in whole disk. After that to get deleted partitions I installed testdisk. I also used deeper search option. Now I'm getting "file system damaged". It shows The hard disk (320GB /298 GiB) seems to small! (<473 GB /441 GB) Check the Harddisk size: HD Jumpers setings, BIOS detection...

  • Document Stored in File System Text Searching and Filtering required in ASP .Net Application

    - by Harryboy
    Hello Experts, We are building a jobsite application in which we will store resumes of all the candidates, which is planned to store on file system. Now We need to search inside that file and provide the result to the user, we need to provide that what is the best solution to implement text searching. I have just tried to identify it and got some reference like IFilter (API or interface) and Lucene.Net (open source), but not sure that is it a right solution. In initial phase it is expected to be around 50,000 resumes and it should be scalable enough if number increases. I just want some case study or some analysis or your suggestions that which is the best method to handle this requirement (Technology ASP .Net) Thanks

    I need to take a file and find the first occurrence of a literal string pattern as a complete line of the file: Acknowledgments: And then I wish to create a new file from the line of match all the way to the end of the file. I expect perl is a good way to do this, but I'm not much of a perl person, alternatively maybe sed is a good way? Please suggest a simple way to reliably accomplish this in Unix.

  • Can I manually map a file extension to an IFilter?

    - by Deane
    I'm working with Microsoft Indexing Service. I have purchased a third-party IFilter to extract XMP metadata from Adobe products. I'm having trouble getting it to work, and it occurs to me that the problem is that I don't actually have the Adobe software installed on my server, so the IFilters are not mapped. Put another way, there's nothing to tell the indexer that ".psd" files should use this DLL rather than the default DLL. Is it possible to manually map file extensions to the IFilter you want to use?

  • What metric captures why my OSX machine is so slow during XCode indexing

    - by Ben Flynn
    My entire machine OSX Lion machine slows down while XCode 4.4 is indexing. The CPU is less than 10% busy, I've got over 500 MB free memory, plenty of disk space, disk IO rate is not high, network activity is not high. Indexing just a few files can take minutes and builds are extremely slow. While this is going on, even loading a new web page in Chrome can be slow. Knowing how to fix it would be great, but more fundamentally how can I measure what is actually going slowly? What metrics should I be looking at? Nothing in Activity Monitor, iostat, top, or sar betray anything about what's going on to me. Even getting a man page is interminable.

  • Rsync and Lazy mode ?

    - by fabien-barbier
    Since transferring or copying a file that is being used sometimes causes corruption of the transferred file, can we define a time interval in which Rsync checks each file in a given directory to see if there is a change within that time interval ? Files that are not changed during that interval will be transferred, while those that have changes will not. Can I do that with rsync ? Or another tool ? Is there a script to add this functionality to Rsync ? Thanks

  • SQL SERVER – Log File Growing for Model Database – model Database Log File Grew Too Big

    - by pinaldave
    After reading my earlier article SQL SERVER – master Database Log File Grew Too Big, I received an email recently from another reader asking why does the log file of model database grow every day when he is not carrying out any operation in the model database. As per the email, he is absolutely sure that he is doing nothing on his model database; he had used policy management to catch any T-SQL operation in the model database and there were none. This was indeed surprising to me. I sent a request to access to his server, which he happily agreed for and within a min, we figured out the issue. He was taking the backup of the model database every day taking the database backup every night. When I explained the same to him, he did not believe it; so I quickly wrote down the following script. The results before and after the usage of the script were very clear. What is a model database? The model database is used as the template for all databases created on an instance of SQL Server. Any object you create in the model database will be automatically created in subsequent user database created on the server. NOTE: Do not run this in production environment. During the demo, the model database was in full recovery mode and only full backup operation was performed (no log backup). Before Backup Script Backup Script in loop DECLARE @FLAG INT SET @FLAG = 1 WHILE(@FLAG < 1000) BEGIN BACKUP DATABASE [model] TO  DISK = N'D:\model.bak' SET @FLAG = @FLAG + 1 END GO After Backup Script Why did this happen? The model database was in full recovery mode and taking full backup is logged operation. As there was no log backup and only full backup was performed on the model database, the size of the log file kept growing. Resolution: Change the backup mode of model database from “Full Recovery” to “Simple Recovery.”. Take full backup of the model database “only” when you change something in the model database. Let me know if you have encountered a situation like this? If so, how did you resolve it? It will be interesting to know about your experience.

    I'm hoping somebody might be able to provide a bit of advice on an issue I am having. I have 1 site where we implemented a 301 redirect on the homepage from http to https. We have links on the homepage to other parts of the site that are not under SSL (in fact there is only one other page under SSL).

  • USB file transfer preparing to copy, but file count climbs indefinitely

    - by Alex
    I have downloaded Ubuntu 12.04 to back up my Windows machine that won't boot and am running Ubuntu from the CD. I copied and pasted a volume of about 160GB to my external HDD. The transfer has been stuck in the "preparing to copy" stage for several hours and is displaying a file/GB count about twice as high as the volume of data actually being copied! The number is now larger than the entire partition that's being copied from! However I know it's doing something because occasionally it pops up with a minor I/O error on this or that file which I then have to click through. I've not had this problem before so I can only assume it's a Linux/Ubuntu thing. More importantly what I want to know is is there any other way to copy it across that will actually work?

  • What are some good resources for learning about file systems? [closed]

    - by Daniel
    I'd like to learn about file system design at a very detailed level. I'm currently in a graduate level operating systems course, and we're currently going over file systems. We mostly discuss papers and such, but our semester long project is to implement a log-structured file system using fuse and a virtual disk. Are there any good books that focus heavily on file system design and implementation? I have some conceptual clouding on things that seem very basic such as "when we say that an inode has pointers to blocks, do we mean anything besides the inode keeping track of block numbers? Is there any other format for 'disk pointers'?" I'm actually looking at file system design to start my career, so I'm probably going to try to implement a more traditional file system with fuse and our virtual disk format after this course is over.

  • How to determine file in "Error opening file for reading" error

    - by Mark Hildreth
    Since Ubuntu 12.04, whenever I open aterm, I get the following error message: Error opening file for reading: Permission denied aterm still opens and runs correctly, but I get that error message. I'd like to figure out what all this is about. Is someone familiar with this specific error for aterm? Otherwise, is there some log that records files that are attempting to be opened so I can determine what file it's complaining about? I've grepped my log files for "aterm" without success. Other tips for determining what the issue is?

  • Why do I need to republish a file when I update it?

    - by user13089
    The story is: I am coding a program and at the same time, i want to share it with my group members using ubuntu. They don't have an Ubuntu One account and what I do is to publish the file and my friends just get the link and the file. But, strangely or not, every time I upload a new version of this file (I add more code and save it), the used link seems to be "outdated" and I need to publish the same file again and to get a new link every time i modify the same file. Couldn't it be possible to save a new version of your file and the same link just "points" to the newer version?

  • .net- open excel file, format the file and save

    - by Lock
    I have an ASP web service that uses the Crystal Reports API to download an Excel report. Now, there is a few things I do not like about the Excel report that Crystal generates: - The column widths are static (as in they are not adjusted for the content). - I can't format the header row to be bold - If I suppress a data column in the report, it comes out in the Excel spreadsheet as a blank column. I currently use PHP to open the excel file, autosize the columns, bold the heading and remove blank columns, although using the PHPExcel class for this doesn't work well when the spreadsheet is only a few 100kb in size. I am thinking if I move this activity into the .NET web service, the performance will be much better. Does anyone know an efficient way of opening a Excel file and performing the operations listed above?

  • How to quickly search through a very large list of strings / records on a database

    - by Giorgio
    I have the following problem: I have a database containing more than 2 million records. Each record has a string field X and I want to display a list of records for which field X contains a certain string. Each record is about 500 bytes in size. To make it more concrete: in the GUI of my application I have a text field where I can enter a string. Above the text field I have a table displaying the (first N, e.g. 100) records that match the string in the text field. When I type or delete one character in the text field, the table content must be updated on the fly. I wonder if there is an efficient way of doing this using appropriate index structures and / or caching. As explained above, I only want to display the first N items that match the query. Therefore, for N small enough, it should not be a big issue loading the matching items from the database. Besides, caching items in main memory can make retrieval faster. I think the main problem is how to find the matching items quickly, given the pattern string. Can I rely on some DBMS facilities, or do I have to build some in-memory index myself? Any ideas? EDIT I have run a first experiment. I have split the records into different text files (at most 200 records per file) and put the files in different directories (I used the content of one data field to determine the directory tree). I end up with about 50000 files in about 40000 directories. I have then run Lucene to index the files. Searching for a string with the Lucene demo program is pretty fast. Splitting and indexing took a few minutes: this is totally acceptable for me because it is a static data set that I want to query. The next step is to integrate Lucene in the main program and use the hits returned by Lucene to load the relevant records into main memory.

  • HTML client-side portable file generation - no external resources or server calls

    - by awashburn
    I have the following situation: I have set up a series of Cron jobs on an internal company server to run various PHP scripts designed to check data integrity. Each PHP script queries a company database, formats the returned query data into an HTML file containing one or more <tables>, and then mails the HTML file to several client emails as an attachment. From my experience, most of the PHP scripts generate HTML files with only a few tables, however there are a few PHP scripts the create HTML files with around 30 tables. HTML files have been chosen as the distribution format of these scans because HTML makes it easy to view many tables at once in a browser window. I would like to add the functionality for the clients to download a table in the HTML file as a CSV file. I anticipate clients using this feature when they suspect a data integrity issue based on the table data. It would be ideal for them to be able to take the table in question, export the data out to a CSV file, and then study it further. Because need for exporting the data to CSV format is at the discretion of the client, unpredictable as to what table will be under scrutiny, and intermittently used I do not want to create CSV files for every table. Normally creating a CSV file wouldn't be too difficult, using JavaScript/jQuery to preform DOM traversal and generate the CSV file data into a string utilizing a server call or flash library to facilitate the download process; but I have one limiting constraint: The HTML file needs to be "portable." I would like the clients to be able to take their HTML file and preform analysis of the data outside the company intranet. Also it is likely these HTML files will be archived, so making the export functionality "self contained" in the HTML files is a highly desirable feature for the two previous reasons. The "portable" constraint of CSV file generation from a HTML file means: I cannot make a server call. This means ALL the file generation must be done client-side. I want the single HTML file attached to the email to contain all the resources to generate the CSV file. This means I cannot use jQuery or flash libraries to generate the file. I understand, for obvious security reasons, that writing out files to disk using JavaScript isn't supported by any browser. I don't want to create a file without the user knowledge; I would like to generate the file using JavaScript in memory and then prompt the user the "download" the file from memory. I have looked into generating the CSV file as a URI however, according to my research and testing, this approach has a few problems: URIs for files are not supported by IE (See Here) URIs in FireFox saves the file with a random file name and as a .part file As much as it pains me, I can accept the fact the IE<=v9 won't create a URI for files. I would like to create a semi-cross-browser solution in which Chrome, Firefox, and Safari create a URI to download the CSV file after JavaScript DOM traversal compiles the data. My Example Table: <table> <thead class="resulttitle"> <tr> <th style="text-align:center;" colspan="3"> NameOfTheTable</th> </tr> </thead> <tbody> <tr class="resultheader"> <td>VEN_PK</td> <td>VEN_CompanyName</td> <td>VEN_Order</td> </tr> <tr> <td class='resultfield'>1</td> <td class='resultfield'>Brander Ranch</td> <td class='resultfield'>Beef</td> </tr> <tr> <td class='resultfield'>2</td> <td class='resultfield'>Super Tree Produce</td> <td class='resultfield'>Apples</td> </tr> <tr> <td class='resultfield'>3</td> <td class='resultfield'>John's Distilery</td> <td class='resultfield'>Beer</td> </tr> </tbody> <tfoot> <tr> <td colspan="3" style="text-align:right;"> <button onclick="doSomething(this);">Export to CSV File</button></td> </tr> </tfoot> </table> My Example JavaScript: <script type="text/javascript"> function doSomething(inButton) { /* locate elements */ var table = inButton.parentNode.parentNode.parentNode.parentNode; var name = table.rows[0].cells[0].textContent; var tbody = table.tBodies[0]; /* create CSV String through DOM traversal */ var rows = tbody.rows; var csvStr = ""; for (var i=0; i < rows.length; i++) { for (var j=0; j < rows[i].cells.length; j++) { csvStr += rows[i].cells[j].textContent +","; } csvStr += "\n"; } /* temporary proof DOM traversal was successful */ alert("Table Name:\t" + name + "\nCSV String:\n" + csvStr); /* Create URI Here! * (code I am missing) */ /* Approach 1 : Auto-download * downloads CSV data but: * In FireFox downloads as randomCharacers.part instead of name.csv * In Chrome downloads without prompting the user * In Safari opens the files in browser (textfile) */ //var hrefData = "data:text/csv;charset=US-ASCII," + encodeURIComponent(csvStr); //document.location.href = hrefData; /* Approach 2 : Right-Click Save As... */ var hrefData = "data:text/csv;charset=US-ASCII," + encodeURIComponent(csvStr); var fileLink = document.createElement("a"); fileLink.href = hrefData; fileLink.innerHTML = "download"; parentTD = inButton.parentNode; parentTD.appendChild(fileLink); parentTD.removeChild(inButton); } </script> I am looking for an example solution in which the above example table can be downloaded as a CSV file: using a URI the user is prompted to save the file the default filename is the name of the table. code works as described in modern versions of FireFox, Safari, & Chrome I have added a <script> tag with the DOM traversal function doSomething(). The real help I need is with formatting the URI to what I want within the doSomething() function.
