  • How can I sort an NSTableColumn of NSStrings ignoring "The " and "A "?

    - by David Barry
    I've got a simple Core Data application that I'm working on to display my movie collection. I'm using an NSTableView, with it's columns bound to attributes of my Core Data store through an NSArrayController object. At this point the columns sort fine(for numeric values) when the column headers are clicked on. The issue I'm having is with the String sorting, they sort, however it's done in standard string fashion, with Uppercase letters preceding lowercase(i.e. Z before a). In addition to getting the case sorting to work properly, I would like to be able to ignore a prefix of "The " or "A " when sorting the strings. What is the best way to go about this in Objective-C/Cocoa?

  • to escape or not to escape: well formed XHTML with diacritics

    - by andresmh
    Say that you have a XHTML document in English but it has accented characters (e.g. meta name="author" content="José"). Let's say you have no control over the HTTP headers. Should the characters be replaced for their corresponding named entities (e.g. &aacute;, etc)? Should the doc type and the xml:lang attribute be set to English? I know I can check the W3C recommendation but I am asking more from a practical point of view.

  • JMS have javax.jms.InvalidDestinationException when client stop working

    - by Tran
    I use JMS for sending requests from a client to a server. My client sends a request to the server. While the server is working with my request, my client stops (network problem) before the server finishes. When the server is finished, it'll return to the client, but the server can't see the client which sent the request to server, at which point, the server will return an exception in log file. The exception is : javax.jms.InvalidDestinationException: Cannot publish to a deleted Destination: temp-queue://ID:PC0092-49463-1344231871819-0:0:9 [^] My question is: what do I need to do in this case? Can I catch or disable this exception? And how can I do it? (Sorry, If my english is not good.)

  • Advantage of using a static member function instead of an equivalent non-static member function?

    - by jonathanasdf
    I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

    - by vic
    Hi, I'd like to know what interesting open-source projects written in Delphi (or FreePascal) you know? I'm not asking for components/components packs, I know there were questions for that. Please do not duplicate answers, vote them up instead ;) Please do not point components/packs/closed-source projects. Please provide at least word of description ;) Two examples from me: PyScripter - Python IDE written in Delphi - hosted at google code (*) HeidiSQL - MySQL Frontend - http://www.heidisql.com/ (*)sorry, as a new user I can't post more than one link :(

  • Storyboard editor layout confusion

    - by drew
    I am having layout problems with the storyboard editor with a fairly simple screen. I have a UIViewController to which I have added a 320x440 UIScrollView at 0,0 followed by a 320x20 UIProgressBar at 0,440. It looks fine in Storyboard editor. I'm not entirely sure how the 20 pixel status bar at the top of the screen is accommodated given the CGRect frame coordinates that Storyboard calculates. On loading ( in -(void)viewDidLoad ), the UIScrollView frame seems to be set to 320x460 pixels at 0,0 but the UIProgressBar is still 320x20 at 0,440. When I add subviews to the UIScrollView, (UIImageViews in particular), they get stretched and get clipped on the screen because although the UIScrollView thinks it is 460 pixels high, it only has 440 pixels of screen to display in. Can anyone point me to a solution? Thanks

  • How to write a virtual conditional breakpoint in java

    - by Phuong Nguyen de ManCity fan
    I'm sorry if the question title may mis-inform you, but I cannot find a proper word to explain that. If you ever working with .NET, you would know that there is Assert class that will automatically wake up and attach debugger if necessary and then have debugger (Visual Studio) pausing at the Assert command, given the Assert command failed. Given I'm running a java program and having debugger connected, then how can I have debugger to break on certain condition without manually setup a break point? I'm expecting something like that: void doSomeThing(String x){ if (x==null) breakDebuggerNow(); }

  • Problem with Qt::QueuedConnection, signal delivered after disconnect

    - by lutku
    Hi, I just discovered interesting behavior of queued connection in Qt 4.6: First queued connection is made: connect(someSender, SIGNAL(completed()), this, SLOT(handleCompletion()), Qt::QueuedConnection) Then someSender sends the signal: emit completed() Before receiving signal (as it is in queue), I disconnect from the signal: disconnect(someSender, SIGNAL(completed()), this, SLOT(handleCompletion()) Still, handleCompletion slot is invoked at next eventloop iteration. I can prevent this from happening by using someSender-blockSignals(true) at correct point, but it feels awful not to mention having some boolean flag to disable slot's functionality. Especially, I feel amazed that this behavior is not mentioned in Qt documentation (at least I haven't found). Finally the question: any sensible way to avoid this from happening?

  • Java: versioned data structures?

    - by Jason S
    I have a data structure that is pretty simple (basically a structure containing some arrays and single values), but I need to record the history of the data structure so that I can efficiently get the contents of the data structure at any point in time. Is there a relatively straightforward way to do this? The best way I can think of would be to encapsulate the whole data structure with something that handles all the mutating operations by storing data in functional data structures, and then for each mutation operation caching a copy of the data structure in a Map indexed by time-ordering (e.g. a TreeMap with real time as keys, or a HashMap with a counter of mutation operations combined with one or more indexes stored in TreeMaps mapping real time / tick count / etc. to mutation operations) any suggestions?

  • calling facebox in a google maps balloon

    - by XGreen
    Hi Guys, I have a gmap balloon. var marker = createMarker(point, '<div style="width:240px" id="mapsball"><h2>Splash of London</h2><img src="_assets/images/themes/shop.jpg" id="mapThumb" width="100" align="right" /><p>110-112 Hoxton Street</p><p>London</p><p>N1 6SH</p><\/div>'); map.addOverlay(marker, icon); and a facebox attached to the click event of the image ('#mapsball') which opens it in a facebox $(function() { $("body").delegate("#mapThumb", "click", function(){ jQuery.facebox('<img src="_assets/images/themes/shop.jpg" align="right"/>'); }); }); this works fine in ff and safari and chrome. but doesn't fire in ie. I don't get a js error in ie so I am assuming it just doesn't get binded. any help would be greatly appreciated.

  • How to design this class hierarchy?

    - by devoured elysium
    I have defined an Event class: Event and all the following classes inherit from Event: AEvent BEvent CEvent DEvent Now, with the info I gather from all these Event classes, I will make a chart. With AEvent and BEvent, I will generate points for that chart, while with CEvent and DEvent I will paint certain regions of the chart. Now, how should I signal this in my class hierarchy? Should I make AEvent and BEvent inherit from PointEvent while CEvent and DEvent inherit from RegionEvent, being that both RegionEvent and PointEvent inherit from Event? Should I add a field with an Enum to Event with 2 values, Point and Region, and each of the child classes set their value to it? Should I use some kind of pattern here? Which one? Thanks.

  • JavaScript function binding (this keyword) is lost after assignment

    - by Ding
    this is one of most mystery feature in JavaScript, after assigning the object method to other variable, the binding (this keyword) is lost var john = { name: 'John', greet: function(person) { alert("Hi " + person + ", my name is " + this.name); } }; john.greet("Mark"); // Hi Mark, my name is John var fx = john.greet; fx("Mark"); // Hi Mark, my name is my question is: 1) what is happening behind the assignment? var fx = john.greet; is this copy by value or copy by reference? fx and john.greet point to two diferent function, right? 2) since fx is a global method, the scope chain contains only global object. what is the value of this property in Variable object?

  • concurrency in Java

    1]What is Non-blocking Concurrency and how is it different. 2] I have heard that this is available in Java. Are there any particular scenarios we should use this feature 3] Is there a difference/advantage of using one of these methods for a collection. What are the trade offs class List { private final ArrayList<String> list = new ArrayList<String>(); void add(String newValue) { synchronized (list) { list.add(newValue); } } } OR private final ArrayList<String> list = Collections.synchronizedMap(); The questions are more from a learning/understanding point of view.

  • Reading PowerPoint Effects with VBA

    - by OneNerd
    I have been working with VBA inside PowerPoint, and have a grasp on most things. What I am struggling with is reading the effect/animation settings for each object. I seem to be able to get a lot of what I need through the Powerpoint.ActivePresentation.Slides(slide_id).TimeLine.MainSequence(seq_num) What confuses me is how to convert the numeric value of Powerpoint.ActivePresentation.Slides(slide_id).TimeLine.MainSequence(seq_num).EffectType to an effect (so looking for a table of values to effects or perhaps a CONST table). Also, how to read in all the different level of effects (like entrance, or emphasis, etc) is really confusing. not to mention I cannot wrap my head around the timeline (which seems like it is not really a timeline). Can anyone point me to any good articles or documentation that discusses how to read the effects and animations properly and fully? Thanks.

  • Why does UIImageView "darken"/saturate PNG images, and can I stop it?

    - by Ben
    I have a PNG file in a UIImageView, and next to that I have an EAGLView which displays the continuation of that same image (long story) as a texture, carved from the same original PNG. The point is, that these images, which should match up flawlessly, actually have somewhat differing color saturation. Normally I'd blame my handling of the PNG texture load in GL, but when I hold Preview (with the PNG) up to the iPhone simulator, it's GL that's spot on, and the UIImageView that's wrong! It's taken the image and made it ever-so-slightly more saturated. The image view is opaque with 100% alpha. I verified this on a clean UIImageView with another PNG file when put next to Preview. Anyone know what's up?

  • Is there a way to get different sizes of the Windows system icons in .NET?

    - by Andrew Watt
    In particular I'd like to be able to get the small (16 x 16) icons at runtime. I tried this: new Icon(SystemIcons.Error, SystemInformation.SmallIconSize) Which supposedly "attempts to find a version of the icon that matches the requested size", but it's still giving me a 32 x 32 icon. I also tried: Size iconSize = SystemInformation.SmallIconSize; Bitmap bitmap = new Bitmap(iconSize.Width, iconSize.Height); using (Graphics g = Graphics.FromImage(bitmap)) { g.DrawIcon(SystemIcons.Error, new Rectangle(Point.Empty, iconSize)); } But that just scales the 32 x 32 icon down into an ugly 16 x 16. I've considered just pulling icons out of the VS Image Library, but I really want them to vary dynamically with the OS (XP icons on XP, Vista icons on Vista, etc.). I'm willing to P/Invoke if that's what it takes.

  • Trying to build automatic audio-conferencing capability into a WebApp

    - by Keller
    Hey all, I'm working with a team of relatively novice programmers, and we are trying to create a site that will have audio-conferencing capabilities such that whenever someone visits the page, they will immediately have audio-conferencing capabilities with everyone else on the page (5 people max). Can anyone point us in a general direction? Should we be looking into building a custom app, leveraging audio conferencing software, or trying to mimic a webex program? Would Adobe Stratus be useful in getting this kind of functionality? Does anyone have any ideas about how we would design something like this on a macro level? Sorry for the noobish question, but any guidance would be deeply appreciated. Thanks, Keller

  • [AS2] Use for variable as parameter and keep it different for each iteration

    - by Adam Kiss
    Hello, I have a basic for loop to loop through buttons and set some stuff and onPress handlers: for (i=1;i<=20;i++){ //do some stuff _root["button"+i].onPress = function(){ someMC.gotoAndStop(i+1); } } However, as I noticed, all buttonsthen link to one and same frame - all point to last i + 1 - Is there any possibility to call gotoAndStop with "static" Number, so in next iteration, it won't change? Edit: Ex. for last statement: Iteration 5 will call gAS /*gotoAndStop:]*/(6); Iteration 6 -> gAS(7); Iteration 7 -> gAS(8);

  • Logictech USB HID controller message

    - by rross
    I have a Logitech game controller(http://www.amazon.com/Logitech-Dual-Action-Game-Pad/dp/B0000ALFCI). I'm using c# and Microsoft's HID driver to track what buttons are being pressed. Each button press sends a Byte Array that has 8 values. The problems is that I don't know what those 8 value represent. Here is an example: 0, 128, 126, 127, 130, 24, 24, 0, 4, 252 0, 128, 126, 127, 130, 40, 40, 0, 4, 252 0, 128, 126, 127, 127, 72, 72, 0, 4, 252 0, 128, 126, 127, 127, 136, 136, 0, 4, 252 Those are the values of the Byte Array for button press 1, 2, 3, 4 respectively. I see where the values are changing, but I'm unsure what they represent. I'm unable to find any specs on Microsoft HID driver. Can someone point me in the right direction?

  • Consuming RSS Feed In PHP

    - by mrduclaw
    I'm trying to use an RSS feed from my blog on the news section on another site. Everything seems to be working fine until I use something like an ellipsis on my blog. The expected output is: One more time…less fail Although this is no joking matter… The actual output is: One more time?less fail Although this is no joking matter… The problem is that ? should be a .... The code I'm using is the same for the first line (the blog title) and the second line (the blog contents) and that code is: $a = utf8_decode($a); print("$a"); Where $a is the string from the RSS feed. Can anyone point in the right direction why that code would work correctly for the body (second line) and not for the title (first line)? Or suggest a better way to do this? Thanks!

  • Ruby socket server thread question: how to send to all clients?

    - by Paul
    I'm making a TCP socket server(ruby). A thread is created for each connected client. At some point I try to send data to all connected clients. The thread aborts on exception while trying.(ruby 1.8.7) require 'socket' # I test it home right now server = TCPServer.new('localhost', 12345); while(session = server.accept) #Here is the thread being created Thread.new(session) do |s| while(msg = s.gets) #Here is the part that causes the error Thread.list.each { |aThread| if aThread != Thread.current #So what I want it to do is to echo the message from one client to all others #But for some reason it doesn't, and aborts on the following string aThread.print "#{msg}\0" end } end end Thread.abort_on_exception = true end What am I doing wrong?

  • Is it possible to detect a scrollbar release event in GWT?

    - by Keith
    I'm building a GWT app where I want to be able to detect when a user releases a scroll bar on one of my ScrollPanels. My use case is that the horizontal scroll bar represents time. Since it's impossible to represent the full range of scrollable time I want to just represent a small window of time with the scroll bar. When the user moves and releases the scroll bar I want to do a smooth recentering where the new center is the release point. I can work out how to do this by building a custom scroll bar widget, but I wanted to check if I was missing some way to do it using a "native" scroll bar first.

  • DBMS for POS software

    - by Andrew Smith
    Hello, I want to develop a POS application in .NET (C#) that would be used to rent items. I have a good idea of what will be done and the famous question that I have is about the DBMS that I should use. I would like to use MySQL database. The question is: If some places use only one computer (no network, no internet connection), can I use a MySQL database in local? Do I need to install MySQL server on all thoses computers to be able to use such a database? I know SQLite but I'm not sure if the limitations can cause problems in the future... I also looked at SQLServer Express versions. (I must consider that other point of sales are using multiple computers and more transactions so there I can't put sqlexpress or sqlite) So can anybody suggest me what I should do in that situation? Thanks
