  • What does LAME text does in MP3 file?

    - by Dims
    I see here http://en.wikipedia.org/wiki/MP3 that MP3 file consists of MP3 headers interchanged with MP3 data. MP3 header consist of few bytes. But here is my MP3 file dump with ID3 tag cut. Header is highlighted with blue. You can see that "LAME3.96" text is highlighted with green. What does it does there? Is this a part of MP3 elementary stream? Or this is the part of some headers I didn't tag?

  • Playing audio from a wav file in iPhone SpeakHere example

    - by Mo
    I'm working with the iPhone SpeakHere example, and I would like to be able to play audio from either the mic (as in the example) or from a wav file. I have working code to play from a particular wav file, which looks like this: NSString *path = [[NSBundle mainBundle] pathForResource:@"basketBall" ofType:@"wav"]; AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio play]; So I'm fine with actually getting the wav to play in the application (I can hook it up to a button, etc.) but I would like it to also behave the same way pushing the "Play" button does after recorded speech, in that it should be connected to the same visualization (which I have modified quite a bit, but essentially shows the current volume, among other things). Thanks for your help!

  • file upload in existing site with jquery and codeigniter

    - by Sam
    I am a new bee to ajax world. I am working on a site which uses jquery and codeigniter which processes big files like 2GB. It basically parses file and stores some extracted data from it, it uses ajax to show how far the files have been processed etc. Now I want to change the way we process files. I want to first store the file on server side and then start the processing. I evaluated upload class of codeigniter but looks like I cannot use it for this purpose as this class works with field_name and I could not find a way to make an ajax call to the upload class. My questions is : What would be suitable for my problem? Thanks in advance, Sam

  • Out of the box approach to upload XML file to the BIRT Server for Processing

    - by Paul
    Hello, I have the BIRT Report Server configured in TOMCAT and it works fine when running reports that require an XML datasource, but that XML file has be available on the network in order for the server to find it and run. Is there an out of the box configuration in the BIRT server that will prompt the user to upload the XML file directly to the server when they try to run a given report that requires an XML data source? This would be handy for users that have the XML datasource stored locally on their C drive and not have to move them to a network server in order to be read by BIRT. Thanks in advance. Paul

  • Simple File-based Record Storage with Fast Text Searching for Compact Framework and Silverlight

    - by Eric Farr
    I have a single table with lots of records ( 100k) that I need to be able to index and search on several text fields. The easiest searches will have the first part of the string specified (eg, LIKE 'ABC%' in SQL). The tougher searches will need to search for any substring within the text fields (eg, LIKE '%ABC%' in SQL). I need to run on the Compact Framework. SQL Compact is a memory hog and overkill for my one table. Besides, I'd like to be able to run on Silverlight 4 eventually. The file and indexes can be generated on the full .NET Framework and I only need read capability on the Compact Framework. My records are not especially large and can be expressed in fix length format. I'm looking for some existing code or libraries to avoid having to write a file-based BTree implementation from scratch.

  • UTF-8 xml file shows Gibberish

    - by Adam
    I have a UTF-8 encoded xml file, which was exported from a Wordpress MySQL database. While the file is saved as UTF-8, and the encoding is UTF-8, I get gibberish instead of the Hebrew text that is supposed to be in there, which looks like this: ™×•×˜×•×ª How can I find the original encoding or charset and convert the text into proper Hebrew? PHP's mb_detect_encoding($str); returns UTF-8 Tried all sorts of php encoding functions, with different settings and input/output charsets, but they all just print different looking gibberish blocks, like: ÃâÃËÃâ¢Ãâ¢ÃËà and ?? ××©×ž× ...Any Ideas how to go about this?

  • Exporting query results to a file on the fly

    - by ercan
    Hi all, I need to export the results of a query to a csv file in an FTP folder. Is it possible to achieve this within a stored procedure? If yes, comes yet another constraint: can I achieve this without sysadmin privileges, aka without using xp_cmdshell + BCP utility? If no to 2., does the caller have to have sysadmin privileges or would it suffice if the SP owner has sysadmin privileges? Here are some more details to the problem: The SP must export and transfer the file on the fly and raise error if something went wrong. The caller must get a response immediately, i.e. in case of no error, he can assume that the results are successfully transferred to the folder. Therefore, a DTS/SSIS job that runs every N minutes is not an option. I know the problem smells like I will have to do this at application level, but I would be more than happy if all those stuff could be done from T-SQL.

  • "a valid provisioning file for this executable was not found" in XCode

    - by dbonneville
    I'm trying to submit my second app to the App Store. I've followed all the instructions to the best of my knowledge, but I keep getting this error when I try to build and run: "a valid provisioning file for this executable was not found" I'm letting XCode auto select the profile automatically. The one I'd like to select is greyed out. But the dropdown selection in the Build tab of the Target window says "profile doesn't match application identifier" The other thing I don't get about this is that the selection dropdown shows "com.mycompany.myapp" and then "ABCDEDFG.com.mycompany.myapp" (both of those made up) so that I see they don't match. I have the unique identifier profile installed in the Organizer and in plist file. I'm totally confused. I have followed the instructions in my book a few times and just can't get it.

  • Include at text file as is in (Python) Sphinx Docs

    - by Gregg Lind
    (using Python-Sphinx Documentation tool) I have a .txt log file I'd like to build into _build/html unaltered. What do I need to alter in conf.py, index.rst, etc. Here is the layout: src/ index.rst some_doc.rst somefile.txt How do I get somefile.txt into the html build? I tried adding a line like this to index.rst: Contents: .. toctree:: :maxdepth: 2 some_doc "somefile.txt" hoping it would work by magic, but no magic here! Assuming this is even possible, what would I put in some_doc.rst to refer/link to that file? Note Yes, I'm aware I could put it in /static and just be done with it, but that seems like a total hack, and ugly.

  • How to display specific data from a file

    - by user1067332
    My program is supposed to ask the user for firstname, lastname, and phone number till the users stops. Then when to display it asks for the first name and does a search in the text file to find all info with the same first name and display lastname and phones of the matches. import java.util.*; import java.io.*; import java.util.Scanner; public class WritePhoneList { public static void main(String[] args)throws IOException { BufferedWriter output = new BufferedWriter(new FileWriter(new File( "PhoneFile.txt"), true)); String name, lname, age; int pos,choice; try { do { Scanner input = new Scanner(System.in); System.out.print("Enter First name, last name, and phone number "); name = input.nextLine(); output.write(name); output.newLine(); System.out.print("Would you like to add another? yes(1)/no(2)"); choice = input.nextInt(); }while(choice == 1); output.close(); } catch(Exception e) { System.out.println("Message: " + e); } } } Here is the display code, when i search for a name, it finds a match but displays the last name and phone number of the same name 3 times, I want it to display all of the possible matches with the first name. import java.util.*; import java.io.*; import java.util.Scanner; public class DisplaySelectedNumbers { public static void main(String[] args)throws IOException { String name; String strLine; try { FileInputStream fstream = new FileInputStream("PhoneFile.txt"); // Get the object of DataInputStream DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); Scanner input = new Scanner(System.in); System.out.print("Enter a first name"); name = input.nextLine(); strLine= br.readLine(); String[] line = strLine.split(" "); String part1 = line[0]; String part2 = line[1]; String part3 = line[2]; //Read File Line By Line while ((strLine= br.readLine()) != null) { if(name.equals(part1)) { // Print the content on the console System.out.print("\n" + part2 + " " + part3); } } }catch (Exception e) {//Catch exception if any System.out.println("Error: " + e.getMessage()); } } }

  • Printing to STDOUT and log file while removing ANSI color codes

    - by Arrieta
    I have the following functions for colorizing my screen messages: def error(string): return '\033[31;1m' + string + '\033[0m' def standout(string): return '\033[34;1m' + string + '\033[0m' I use them as follows: print error('There was a problem with the program') print "This is normal " + standout("and this stands out") I want to log the output to a file (in addition to STDOUT) WITHOUT the ANSI color codes, hopefully without having to add a second "logging" line to each print statement. The reason is that if you simply python program.py > out then the file out will have the ANSI color codes, which look terrible if you open in a plain text editor. Any advice?

  • Intermittent issue - IIS offering to donwload ASPX file instead of executing

    - by Nataliya
    We're getting an intermittent problem with the homepage of our site when IIS will suddenly start offering to download the ASPX file instead of executing it. It happens about once a month, on a random basis. If I open the file in Notepad and re-save it (without making a single change to the code), IIS starts executing the script as normal and doesn't offer the download any more. I can't get my head round this, considering that we can't reproduce the problem. Also, I can't really play with it and test anything when the problem occurs as this is the homepage of the site and needs fixing asap. Any ideas what could be causing this? Files are written to the server over Filezilla FTP. Looks like the homepage is the only page affected. Server is Windows Server 2003, IIS 6.0 with all the latest patches (we actually run two of them, load balanced, and the problem can occur on either server on a random basis). Can't see anything in the Event logs or IIS log.

  • Delete files from blobstore using file serving URL

    - by Arturo
    In my app (GWT on GAE) we are storing on our database the serving URL that is stored on blobstore. When user selects one of these files and clicks "delete", we need to delete the file from blobstore. This is our code, but it is not deleting the file at all: public void remove(String fileURL) { BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); String key = getBlobKeyFromURL(box.getImageURL()); BlobKey blobKey = new BlobKey(key); blobstoreService.delete(blobKey); } Where fileURL looks like this: http://lh6.ggpht.com/d5VC0ywISACeJRiC3zkzaZug-tPsaI_LGt93-e_ATGTCwnGLao4yTWjLVppQ And getBlobKeyFromURL() would return what is after the last "/", in this example: d5VC0ywISACeJRiC3zkzaZug-tPsaI_LGt93-e_ATGTCwnGLao4yTWjLVppQ Could you please advice? Thanks

  • Best language to use when exporting an excel file

    - by Aaron
    I want to write a macro program that takes in data from a text file and then arranges it in a specific manner in an excel file. I don't know which language has the best features for dealing with Excel. I prefer java, and I see someone made an api called JExcelApi, but I'm not sure about it's capabilities. I would like to be able to generate a graph automatically in excel based on the data in a certain column. Is this possible in any language? I would guess that Microsoft's VB or C# would have an advanced feature such as this, but I'm not sure. Thanks.

  • Link to another file in chrome extension

    - by Hintswen
    I want to have a link in the popup.html file for my extension that loads another file (which will be included with the extension) how can I do this? or will I need to keep it in the same page? I tried using this code: <a href="/mail.html"> <img id="newmail_icon" src="" width="16" height="16" /> <span id="newmail">loading</span><br /> </a> But when I click the link nothing happens. I just found out that adding target="_blank" to the link will make it work and open in a new tab, but I can't get it to open in the popup. I have tried target="_self" but it didn't do anything.

  • Raw Video file from website

    - by Charlie
    I would like to make an app that will download videos files that can be played later. At first i thought I could have a UIWeb view and then try to access the cache of it and get the file that way but unfortunately i don't have access to that. After trying that my next thought would be get the direct link to the video file. Essentially what download helper does on fire fox. Any idea of where i could look at for help or any body have any better idea? Is there any stringByEvaluatingjavascript that might be of use or is there away to access the cache on a webview in your own app? Thanks for any help!

  • OpenCV to use in memory buffers or file pointers

    - by The Unknown
    The two functions in openCV cvLoadImage and cvSaveImage accept file path's as arguments. For example, when saving a image it's cvSaveImage("/tmp/output.jpg", dstIpl) and it writes on the disk. Is there any way to feed this a buffer already in memory? So instead of a disk write, the output image will be in memory. I would also like to know this for both cvSaveImage and cvLoadImage (read and write to memory buffers). Thanks! My goal is to store the Encoded (jpeg) version of the file in Memory. Same goes to cvLoadImage, I want to load a jpeg that's in memory in to the IplImage format.

  • Reading an Excel file in PHP

    - by Dinah
    I'm trying to read an Excel file (Office 2003). There is an Excel file that needs to be uploaded and its contents parsed. Via Google, I can only find answers to these related (and insufficient topics): generating Excel files, reading Excel XML files, reading Excel CSV files, or incomplete abandoned projects. I own Office 2003 so if I need any files from there, they are available. It's installed on my box but isn't and can't be installed on my shared host. Edit: so far all answers point to PHP-ExcelReader and/or this additional article about how to use it.
