  • Adobe Air: Read and Write MP3 or JPG from local directory and switch bytes

    - by Max
    I would like to make my local jpg and mp3 files kind of unreadable (without encoding) by just putting the first 100 bytes from the beginning of the file to the end and then saving the file with a .dat extension. I know I have to use the byte array but can't get it work. I would also need then a small function to read that file and put the 100bytes back to the front so that I can play/display the file. It would be great if you could post the whole function because I am quite new to Air so that I fully understand. Thank You!!!!

    - by notapipe
    I have a huge (4,5 GB) csv file.. I need to perform basic cut and paste, replace operations for some columns.. the data is pretty well organized.. the only problem is I cannot play with it with Excel because of the size (2000 rows, 550000 columns). here is some part of the data: ID,Affection,Sex,DRB1_1,DRB1_2,SENum,SEStatus,AntiCCP,RFUW,rs3094315,rs12562034,rs3934834,rs9442372,rs3737728 D0024949,0,F,0101,0401,SS,yes,?,?,A_A,A_A,G_G,G_G D0024302,0,F,0101,7,SN,yes,?,?,A_A,G_G,A_G,?_? D0023151,0,F,0101,11,SN,yes,?,?,A_A,G_G,G_G,G_G I need to remove 4th, 5th, 6th, 7th, 8th and 9th columns; I need to find every _ character from column 10 onwards and replace it with a space ( ) character; I need to replace every ? with zero (0); I need to replace every comma with a tab; I need to remove first row (that has column names; I need to replace every 0 with 1, every 1 with 2 and every ? with 0 in 2nd column; I need to replace F with 2, M with 1 and ? with 0 in 3rd column; so that in the resulting file the output reads: D0024949 1 2 A A A A G G G G D0024302 1 2 A A G G A G 0 0 D0023151 1 2 A A G G G G G G (both input and output should read one line per row, ne extra blank row) Is there a memory efficient way of doing that with java(and I need a code to do that) or a usable tool for playing with this large data so that I can easily apply Excel functionality..

  • How to write my own download manager using Objective C for iOS devices

    - by Saurabh
    I am writing a download manager for iPhone using objective C. I am using ASIHTTP framework and its working great. But my problem is I am not able to download from file sharing sites like filesonic, rapidshare, hotfile etc. I want to know how can I get download (actual download) url from these sites, or at least how these sites are hiding this info (and where), so I can get that somehow... Is there any open source library or framework to help me with this? How firefox or other desktop browser get this link? Any help will be much appreciated! Update 1 : I don't want to bypass their advertising and revenue streams. Almost all file sharing companies also provide free downloads with low bandwidth, I only want to use that service. there are many download managers available now for iPhone like - "Downloads Lite". I just want to build a similar functionality.

  • How to write an intersects for Shapes in android

    - by Rafael T
    I have an written an Object called Shape which has a Point representing the topLeftCorner and a Dimension with represents its width and height. To get the topRightCorner I can simply add the width to the topLeftPoint.x. I use to rotate them on a certain degree around their center. The problem after the rotation is, that my intersects(Shape) method fails, because it does not honor the rotation of the Shapes. The rotation will be the same for each Shape. My current implementation looks like this inside my Shape Object: public boolean intersects(Shape s){ // functions returning a Point of shape s return intersects(s.topLeft()) || intersects(s.topRight()) || intersects(s.bottomLeft()) || intersects(s.bottomRight()) || intersects(s.leftCenter()) || intersects(s.rightCenter()) || intersects(s.center()); } public boolean intersects(Point p){ return p.x >= leftX() && p.x <= rightX() && p.y >= topY() && p.y <= bottomY(); } Basically I need functions like rotatedLeftX() or rotatedTopRight() to work properly. Also for that calculation I think it doesn't matter when the topLeft point before a rotation of ie 90 will turn into topRight... I already read this and this Question here, but do not understand it fully.

  • How to write web services in java

    - by gurupriyan.e
    Though this might appear as a duplicate of Java Web Services , I would like to know Where to start and to continue.In the past, I have invested so much of time to find where to start but I wasn't able to. There are so many jargons and chaos (at least for me!) while reading the pages about web services. There are so many terms - like JAX-RPC, JAX-WS, Axis, Rest, Servlet as WebService, EJB's as Web Service and other terms that I don't know. Can this User group consolidate and give a highlevel overview of Java Web Services which is easy to understand and follow? I appreciate your kindness and thanks for your help.

  • How do I write an overload operator where both arguments are interface

    - by Eric Girard
    I'm using interface for most of my stuff. I can't find a way to create an overload operator + that would allow me to perform an addition on any objects implementing the IPoint interface Code interface IPoint { double X { get; set; } double Y { get; set; } } class Point : IPoint { double X { get; set; } double Y { get; set; } //How and where do I create this operator/extension ??? public static IPoint operator + (IPoint a,IPoint b) { return Add(a,b); } public static IPoint Add(IPoint a,IPoint b) { return new Point { X = a.X + b.X, Y = a.Y + b.Y }; } } //Dumb use case : public class Test { IPoint _currentLocation; public Test(IPoint initialLocation) { _currentLocation = intialLocation } public MoveOf(IPoint movement) { _currentLocation = _currentLocation + intialLocation; //Much cleaner/user-friendly than _currentLocation = Point.Add(_currentLocation,intialLocation); } }

  • block write access to table from an application in mysql

    - by hoberion
    Hello, We have a CMS plugin that writes statistics to 1 table, this creates performance issues on the entire platform. We decided to use another statistics plugin which can connect to a different database server (the first plugin couldn't!) however we need parts of the first plugin. I want to lock the statistics table to prevent misusage (not allowed to drop it by the developer) So I was wondering if a lock table could do this or if I can implement some sort of read only table

  • Write XML File from a flex application back to a rails Server

    - by Markus
    Hi everybody, I have a XML-file, which I want to send to a rails server. To do so I use the following code: <mx:HTTPService id="dataService" result="resultHandler(event)" resultFormat="e4x"/> In a Function triggered by a save button, I do the following: var params:Object = {}; params["xml_file"] = xmlDoc; dataService.method = "POST"; dataService.url = "http://localhost:3000/containers"; dataService.send(params); Unfortunately there is always the Problem (see below) appearing. If I remove the params var, it runs a GET Request... [RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream-Fehler. URL: http://localhost:3000/containers"]. URL: http://localhost:3000/containers"] what could be the problem? Thanks for any hints! Markus

  • How to write this in a simpler less ridiculous way

    - by Richard Knop
    This just seems absurd to me. Should I use array instead or is there some other better solution? $('.hoursRange').change(function() { if ('0' == $(this).val()) { $(this).val('00'); return false; } if ('1' == $(this).val()) { $(this).val('01'); return false; } if ('2' == $(this).val()) { $(this).val('02'); return false; } if ('3' == $(this).val()) { $(this).val('03'); return false; } if ('4' == $(this).val()) { $(this).val('04'); return false; } if ('5' == $(this).val()) { $(this).val('05'); return false; } if ('6' == $(this).val()) { $(this).val('06'); return false; } if ('7' == $(this).val()) { $(this).val('07'); return false; } });

  • How to write a JOIN statement to combine data from disparate tables

    - by Amarundo
    I have the following 2 procedures that I use as my source for a report.

  • Why does Excel now give me already existing name range error on Copy Sheet?

    - by WilliamKF
    I've been working on a Microsoft Excel 2007 spreadsheet for several days. I'm working from a master template like sheet and copying it to a new sheet repeatedly. Up until today, this was happening with no issues. However, in the middle of today this suddenly changed and I do not know why. Now, whenever I try to copy a worksheet I get about ten dialogs, each one with a different name range object (shown below as 'XXXX') and I click yes for each one: A formula or sheet you want to move or copy contains the name 'XXXX', which already exists on the destination worksheet. Do you want to use this version of the name? To use the name as defined in destination sheet, click Yes. To rename the range referred to in the formula or worksheet, click No, and enter a new name in the Name Conflict dialog box. The name range objects refer to cells in the sheet. For example, E6 is called name range PRE on multiple sheets (and has been all along) and some of the formulas refer to PRE instead of $E$6. One of the 'XXXX' above is this PRE. These name ranges should only be resolved within the sheet within which they appear. This was not an issue before despite the same name range existing on multiple sheets before. I want to keep my name ranges. What could have changed in my spreadsheet to cause this change in behavior? I've gone back to prior sheets created this way and now they give the message too when copied. I tried a different computer and a different user and the same behavior is seen everywhere. I can only conclude something in the spreadsheet has changed. What could this be and how can I get back the old behavior whereby I can copy sheets with name ranges and not get any errors? Looking in the Name Manager I see that the name ranges being complained about show twice, once as scope Template and again as scope Workbook. If I delete the scope Template ones the error goes away on copy however, I get a bunch of #REF errors. If I delete the scope Workbook ones, all seems okay and the errors on copy go away too, so perhaps this is the answer, but I'm nervous about what effect this deletion will have and wonder how the Workbook ones came into existence in the first place. Will it be safe to just delete the Workbook name manager scoped entries and how might these have come into existence without my knowing it to begin with?
