  • How to make a custom NSFormatter work correctly on Snow Leopard?

    - by Nathan
    I have a custom NSFormatter attached to several NSTextFields who's only purpose is to uppercase the characters as they are typed into field. The entire code for my formatter is included below. The stringForObjectValue() and getObjectValue() implementations are no-ops and taken pretty much directly out of Apple's documentation. I'm using the isPartialStringValid() method to return an uppercase version of the string. This code works correctly in 10.4 and 10.5. When I run it on 10.6, I get "strange" behaviour where text fields aren't always render the characters that are typed and sometimes are just displaying garbage. I've tried enabling NSZombie detection and running under Instruments but nothing was reported. I see errors like the following in "Console": HIToolbox: ignoring exception '*** -[NSCFString replaceCharactersInRange:withString:]: Range or index out of bounds' that raised inside Carbon event dispatch ( 0 CoreFoundation 0x917ca58a __raiseError + 410 1 libobjc.A.dylib 0x94581f49 objc_exception_throw + 56 2 CoreFoundation 0x917ca2b8 +[NSException raise:format:arguments:] + 136 3 CoreFoundation 0x917ca22a +[NSException raise:format:] + 58 4 Foundation 0x9140f528 mutateError + 218 5 AppKit 0x9563803a -[NSCell textView:shouldChangeTextInRange:replacementString:] + 852 6 AppKit 0x95636cf1 -[NSTextView(NSSharing) shouldChangeTextInRanges:replacementStrings:] + 1276 7 AppKit 0x95635704 -[NSTextView insertText:replacementRange:] + 667 8 AppKit 0x956333bb -[NSTextInputContext handleTSMEvent:] + 2657 9 AppKit 0x95632949 _NSTSMEventHandler + 209 10 HIToolbox 0x93379129 _ZL23DispatchEventToHandlersP14EventTargetRecP14OpaqueEventRefP14HandlerCallRec + 1567 11 HIToolbox 0x933783f0 _ZL30SendEventToEventTargetInternalP14OpaqueEventRefP20OpaqueEventTargetRefP14HandlerCallRec + 411 12 HIToolbox 0x9339aa81 SendEventToEventTarget + 52 13 HIToolbox 0x933fc952 SendTSMEvent + 82 14 HIToolbox 0x933fc2cf SendUnicodeTextAEToUnicodeDoc + 700 15 HIToolbox 0x933fbed9 TSMKeyEvent + 998 16 HIToolbox 0x933ecede TSMProcessRawKeyEvent + 2515 17 AppKit 0x95632228 -[NSTextInputContext handleEvent:] + 1453 18 AppKit 0x9562e088 -[NSView interpretKeyEvents:] + 209 19 AppKit 0x95631b45 -[NSTextView keyDown:] + 751 20 AppKit 0x95563194 -[NSWindow sendEvent:] + 5757 21 AppKit 0x9547bceb -[NSApplication sendEvent:] + 6431 22 AppKit 0x9540f6fb -[NSApplication run] + 917 23 AppKit 0x95407735 NSApplicationMain + 574 24 macsetup 0x00001f9f main + 24 25 macsetup 0x00001b75 start + 53 ) Can anybody shed some light on what is happening?

  • Toggle Blind Effect

    - by flipflopmedia
    Is there a way to alter this script to be used as the blind effect. // Andy Langton's show/hide/mini-accordion - updated 23/11/2009 // Latest version @ http://andylangton.co.uk/jquery-show-hide // this tells jquery to run the function below once the DOM is ready $(document).ready(function() { // choose text for the show/hide link - can contain HTML (e.g. an image) var showText=''; var hideText=''; // initialise the visibility check var is_visible = false; // append show/hide links to the element directly preceding the element with a class of "toggle" $('.toggle').prev().append(' '+showText+''); // hide all of the elements with a class of 'toggle' $('.toggle').hide(); // capture clicks on the toggle links $('a.toggleLink').click(function() { // switch visibility is_visible = !is_visible; // toggle the display - uncomment the next line for a basic "accordion" style //$('.toggle').hide();$('a.toggleLink').html(showText); $(this).parent().next('.toggle').toggle('slow'); // return false so any link destination is not followed return false; }); }); FYI- Where it says: var showText=''; var hideText=''; It was originally: var showText='Show'; var hideText='Hide'; I deleted the Show/Hide Text because I am applying the link to different areas of text. I like the Blind effect, vs. this Toggle effect, and need to know how to apply it, if possible. I cannot find a basic Blind effect script that allows the use of applying the link to ANY text, vs. a button or static text. Thanks! Hope you can help! Tracy

  • Conflict between two Javascripts (MailChimp validation etc. scripts & jQuery hSlides.js)

    - by Brian
    I have two scripts running on the same page, one is the jQuery.hSlides.js script http://www.jesuscarrera.info/demos/hslides/ and the other is a custom script that is used for MailChimp list signup integration. The hSlides panel can be seen in effect here: http://theatricalbellydance.com. I've turned off the MailChimp script because it was conflicting with the hSlides script, causing it not to to fail completely (as seen here http://theatricalbellydance.com/home2/).

  • What is default javac source mode (assert as identifier compilation)?

    - by waste
    According to Orcale's Java7 assert guide: source mode 1.3 (default) — the compiler accepts programs that use assert as an identifier, but issues warnings. In this mode, programs are not permitted to use the assert statement. source mode 1.4 — the compiler generates an error message if the program uses assert as an identifier. In this mode, programs are permitted to use the assert statement. I wrote such class: package mm; public class ClassTest { public static void main(String[] arg) { int assert = 1; System.out.println(assert); } } It should compile fine if Oracle's info right (1.3 is default source mode). But I got errors like this: $ javac -version javac 1.7.0_04 $ javac -d bin src/mm/* src\mm\ClassTest.java:5: error: as of release 1.4, 'assert' is a keyword, and may not be used as an identifier int assert = 1; ^ (use -source 1.3 or lower to use 'assert' as an identifier) src\mm\ClassTest.java:6: error: as of release 1.4, 'assert' is a keyword, and may not be used as an identifier System.out.println(assert); ^ (use -source 1.3 or lower to use 'assert' as an identifier) 2 errors I added manually -source 1.3 and it issued warnings but compiled fine. It seems that Oracle's information is wrong and 1.3 is not default source mode. Which one is it then?

  • Algorithm for finding the best routes for food distribution in game

    - by Tautrimas
    Hello, I'm designing a city building game and got into a problem. Imagine Sierra's Caesar III game mechanics: you have many city districts with one market each. There are several granaries over the distance connected with a directed weighted graph. The difference: people (here cars) are units that form traffic jams (here goes the graph weights). Note: in Ceasar game series, people harvested food and stockpiled it in several big granaries, whereas many markets (small shops) took food from the granaries and delivered it to the citizens. The task: tell each district where they should be getting their food from while taking least time and minimizing congestions on the city's roads. Map example Sample diagram Suppose that yellow districts need 7, 7 and 4 apples accordingly. Bluish granaries have 7 and 11 apples accordingly. Suppose edges weights to be proportional to their length. Then, the solution should be something like the gray numbers indicated on the edges. Eg, first district gets 4 apples from the 1st and 3 apples from the 2nd granary, while the last district gets 4 apples from only the 2nd granary. Here, vertical roads are first occupied to the max, and then the remaining workers are sent to the diagonal paths. Question What practical and very fast algorithm should I use? I was looking at some papers (Congestion Games: Optimization in Competition etc.) describing congestion games, but could not get the big picture. Any help is very appreciated! P. S. I can post very little links and no images because of new user restriction.

  • MySQL ORDER BY DESC is fast but ASC is very slow

    - by Pepper
    Hello, I'm completely stumped on this one. For some reason when I sort this query by DESC it's super fast, but if sorted by ASC it's extremely slow. This takes about 150 milliseconds: SELECT posts.id FROM posts USE INDEX (published) WHERE posts.feed_id IN ( 4953,622,1,1852,4952,76,623,624,10 ) ORDER BY posts.published DESC LIMIT 0, 50; This takes about 32 seconds: SELECT posts.id FROM posts USE INDEX (published) WHERE posts.feed_id IN ( 4953,622,1,1852,4952,76,623,624,10 ) ORDER BY posts.published ASC LIMIT 0, 50; The EXPLAIN is the same for both queries. id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE posts index NULL published 5 NULL 50 Using where I've tracked it down to "USE INDEX (published)". If I take that out it's the same performance both ways. But the EXPLAIN shows the query is less efficient overall. id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE posts range feed_id feed_id 4 \N 759 Using where; Using filesort And here's the table. CREATE TABLE `posts` ( `id` int(20) NOT NULL AUTO_INCREMENT, `feed_id` int(11) NOT NULL, `post_url` varchar(255) NOT NULL, `title` varchar(255) NOT NULL, `content` blob, `author` varchar(255) DEFAULT NULL, `published` int(12) DEFAULT NULL, `updated` datetime NOT NULL, `created` datetime NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `post_url` (`post_url`,`feed_id`), KEY `feed_id` (`feed_id`), KEY `published` (`published`) ) ENGINE=InnoDB AUTO_INCREMENT=196530 DEFAULT CHARSET=latin1; Is there a fix for this? Thanks!

    - by Michael
    I was attempting to clean up the implementation for a sub-panel on a navigation controller stack, so that the navigation bar could be customized in the XIB instead of doing it manually in the viewDidLoad method. The original (working) setup had the XIB set up with the "File's Owner" class set to the view controller class, and then the view at the top level. This works fine. In the "Interface Builder User Guide", p. 71, it describes the recommended way to build the XIBs for sub-panels ("additional navigation levels"). This approach leaves the "File's Owner" class as NSObject, but adds a UIViewController at the top level, and nests the view (and navigation item) underneath it. The UIViewController's view automatically gets connected to the contained view. When I try to push the controller init'd with this new XIB, the app crashes because of a missing view: SettingsViewController *controller = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; 2010-04-23 11:17:37.135 xxxx[1173:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsTestView" nib but the view outlet was not set.' I've double checked everything, and tried building a clean XIB from scratch, but get the same result. I looked through a number of the code sample projects, and NONE of them use the documented/recommended approach--they all use the File's Owner class and manually set up the navigation bar in viewDidLoad like I originally had it. Is it possible to get it working the "recommended" way? Thanks! Michael

  • jQuery aspx error function always called, even with apparently valid return data

    - by M Katz
    I am making an ajax call using jQuery (jquery-1.5.2.min.js). The server receives the call. fiddler shows the response text coming back apparently correct. But back in javascript my error: function is called instead of my success: function, and the data of the parameters to the error function don't give much clue as to the problem. Here's the function where I make the initial call: function SelectCBGAtClickedPoint() { $.ajax( { type: "GET", dataType: "text", url: "http://localhost/ajax/SelectCBGAtPoint/1/2", success: function( msg ) { alert( "success: " + msg ); }, error: function( jqXHR, textStatus, errorThrown ) { alert( "error: " + jqXHR + textStatus + errorThrown ); } } ); } Here's the function where I handle the call in my cherrypy server code: def ajax( ajax, *args ): with lock: print "ajax request received: " + str( args ) cherrypy.response.headers[ "Content-Type" ] = "application/text" return "{ x: 0 }" Cherrypy is an odd beast, and I was thinking the problem must lie there. But as I say, I see both the query go out and the response come back in Fiddler. Here is what Fiddler shows as the raw view of the response: HTTP/1.1 200 OK Date: Mon, 11 Apr 2011 17:49:25 GMT Content-Length: 8 Content-Type: application/text Server: CherryPy/3.2.0 { x: 0 } Looks good, but then back in javascript, I get into the error: function, with the following values for the parameters (as shown in firebug): errorThrown = "" jqXHR = Object { readyState=0, status=0, statusText="error"} statusText = "error" I don't know where that word "error" is coming from. That string does not appear anywhere in my cherrypy server code. Note that even though I'm returning a JSON string I've set the send and receive types to "text" for now, just to simplify in order to isolate the problem. Any ideas why I'm getting this "error" reply, even when errorThrown is empty? Could it be that I haven't properly "initialized" either jQuery or jQuery.ajax?

  • Linq duplicate removal with a twist

    - by Danthar
    I got a list that contains al the status items of each order. The problem that i have is that i need to remove all the items of which the status - logdate combination is not the highest. e.g var inputs = new List<StatusItem>(); //note that the 3th id is simply a modifier that adds that amount of secs //to the current datetime, to make testing easier inputs.Add(new StatusItem(123, 30, 1)); inputs.Add(new StatusItem(123, 40, 2)); inputs.Add(new StatusItem(123, 50, 3)); inputs.Add(new StatusItem(123, 40, 4)); inputs.Add(new StatusItem(123, 50, 5)); inputs.Add(new StatusItem(100, 20, 6)); inputs.Add(new StatusItem(100, 30, 7)); inputs.Add(new StatusItem(100, 20, 8)); inputs.Add(new StatusItem(100, 30, 9)); inputs.Add(new StatusItem(100, 40, 10)); inputs.Add(new StatusItem(100, 50, 11)); inputs.Add(new StatusItem(100, 40, 12)); var l = from i in inputs group i by i.internalId into cg select from s in cg group s by s.statusId into sg select sg.OrderByDescending(n => n.date).First() ; This creates a list that returnes me the following: order 123 status 30 date 4/9/2010 6:44:21 PM order 123 status 40 date 4/9/2010 6:44:24 PM order 123 status 50 date 4/9/2010 6:44:25 PM order 100 status 20 date 4/9/2010 6:44:28 PM order 100 status 30 date 4/9/2010 6:44:29 PM order 100 status 40 date 4/9/2010 6:44:32 PM order 100 status 50 date 4/9/2010 6:44:31 PM This is ALMOST correct. However that last line which has status 50 needs to be filtered out as well because it was overruled by status 40 in the historylist. U can tell by the fact that its date is lower then the "last" status-item with the status 40. I was hoping someone could give me some pointers because im stuck.

  • Regex statements for date ranges <=4/1/2009 and <=10/01/2009

    - by reggiereg
    Hi, I need serious help building two Regex statements for a project. The software we're using ONLY accepts Regex for validation. I need one that fires for any date <4/1/2009 and a second that fires for any date <10/1/2009 My co-worker gave me the following code to check for <=10/01/2010, but it checks leap years and all that stuff. I need something a little more streamlined than this in the MM/DD/YYYY format.

  • Get percentiles of data-set with group by month

    - by Cylindric
    Hello, I have a SQL table with a whole load of records that look like this: | Date | Score | + -----------+-------+ | 01/01/2010 | 4 | | 02/01/2010 | 6 | | 03/01/2010 | 10 | ... | 16/03/2010 | 2 | I'm plotting this on a chart, so I get a nice line across the graph indicating score-over-time. Lovely. Now, what I need to do is include the average score on the chart, so we can see how that changes over time, so I can simply add this to the mix: SELECT YEAR(SCOREDATE) 'Year', MONTH(SCOREDATE) 'Month', MIN(SCORE) MinScore, AVG(SCORE) AverageScore, MAX(SCORE) MaxScore FROM SCORES GROUP BY YEAR(SCOREDATE), MONTH(SCOREDATE) ORDER BY YEAR(SCOREDATE), MONTH(SCOREDATE) That's no problem so far. The problem is, how can I easily calculate the percentiles at each time-period? I'm not sure that's the correct phrase. What I need in total is: A line on the chart for the score (easy) A line on the chart for the average (easy) A line on the chart showing the band that 95% of the scores occupy (stumped) It's the third one that I don't get. I need to calculate the 5% percentile figures, which I can do singly: SELECT MAX(SubQ.SCORE) FROM (SELECT TOP 45 PERCENT SCORE FROM SCORES WHERE YEAR(SCOREDATE) = 2010 AND MONTH(SCOREDATE) = 1 ORDER BY SCORE ASC) AS SubQ SELECT MIN(SubQ.SCORE) FROM (SELECT TOP 45 PERCENT SCORE FROM SCORES WHERE YEAR(SCOREDATE) = 2010 AND MONTH(SCOREDATE) = 1 ORDER BY SCORE DESC) AS SubQ But I can't work out how to get a table of all the months. | Date | Average | 45% | 55% | + -----------+---------+-----+-----+ | 01/01/2010 | 13 | 11 | 15 | | 02/01/2010 | 10 | 8 | 12 | | 03/01/2010 | 5 | 4 | 10 | ... | 16/03/2010 | 7 | 7 | 9 | At the moment I'm going to have to load this lot up into my app, and calculate the figures myself. Or run a larger number of individual queries and collate the results.

  • Capturing time intervals when somebody was online? How would you impement this feature?

    - by Kirzilla
    Hello, Our aim is to build timelines saying about periods of time when user was online. (It really doesn't matter what user we are talking about and where he was online) To get information about onliners we can call API method, someservice.com/api/?call=whoIsOnline whoIsOnline method will give us a list of users currently online. But there is no API method to get information about who IS NOT online. So, we should build our timelines using information we got from whoIsOnline. Of course there will be a measurement error (we can't track information in realtime). Let's suppose that we will call whoIsOnline method every 2 minutes (yes, we will run our script by cron every 2 minutes). For example, calling whoIsOnline at 08:00 will return Peter_id Michal_id Andy_id calling whoIsOnline at 08:02 will return Michael_id Andy_id George_id As you can see, Peter has gone offline, but we have new onliner - George. Available instruments are Db(MySQL) / text files / key-value storage (Redis/memcache); feel free to choose any of them (or even all of them). So, we have to get information like this George_id was online... 12 May: 08:02-08:30, 12:40-12:46, 20:14-22:36 11 May: 09:10-12:30, 21:45-23:00 10 May: was not online And now question... How would you store information to implement such timelines? How would you query/calculate information about periods of time when user was online? Additional information.. You cannot update information about offline users, only users who are "currently" online. Solution should be flexible: timeline information could be represented relating to any timezone. We should keep information only for last 7 days. Every user seen online is automatically getting his own identifier in our database. Uff.. it was really hard for me to write it because my English is pretty bad, but I hope my question will be clear for you. Thank you.

  • Office 2003 interop problems, interface, method not found.

    - by Snake
    This problem is making me crazy. Actually I have multiple problems. First one: Why on earth are is there a _Worksheet and a Worksheetinterface in the Excel interop. They both look the same, except for some attributes on the methods. It's confusing! Second of all: my job today is making a VB.NET file more strict, by settings Option Strict On and Option Explicit On While it works for most files, I'm bumping into a problem. Here's a little code piece: Private _pivotTable As Excel.PivotTable With _pivotTable pvf = .AddDataField(pvc) End With PivotTable.AddDataField is defined on the MSDN page: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.pivottable.adddatafield(office.11).aspx When I check my local Interop dll w/ Reflector that method is NOT there. When I run the application, and step through it, the method just works. When I try to step INTO the method, I get an LateBound Exception. WTF? So the question is: why are the interfaces defined more than once (twice sometimes?). 2nd question. AddDataField trouble

  • How to setup Lucene search for a B2B web app?

    - by Bill Paetzke
    Given: 5000 databases (spread out over 5 servers) 1 database per client (so you can infer there are 1000 clients) 2 to 2000 users per client (let's say avg is 100 users per client) Clients (databases) come and go every day (let's assume most remain for at least one year) Let's stay agnostic of language or sql brand, since Lucene (and Solr) have a breadth of support The Question: How would you setup Lucene search so that each client can only search within its database? How would you setup the index(es)? Would you need to add a filter to all search queries? If a client cancelled, how would you delete their (part of the) index? (this may be trivial--not sure yet) Possible Solutions: Make an index for each client (database) Pro: Search is faster (than one-index-for-all method). Indices are relative to the size of the client's data. Con: I'm not sure what this entails, nor do I know if this is beyond Lucene's scope. Have a single, gigantic index with a database_name field. Always include database_name as a filter. Pro: Not sure. Maybe good for tech support or billing dept to search all databases for info. Con: Search is slower (than index-per-client method). Flawed security if query filter removed. For Example: Joel Spolsky said in Podcast #11 that his hosted web app product, FogBugz On-Demand, uses Lucene. He has thousands of on-demand clients. And each client gets their own database. His situation is quite similar to mine. Although, he didn't elaborate on the setup (particularly indices); hence, the need for this question. One last thing: I would also accept an answer that uses Solr (the extension of Lucene). Perhaps it's better suited for this problem. Not sure.

  • Passing Key-Value pair to a COM method in C#

    - by Sinnerman
    Hello, I have the following problem: I have a project in C# .Net where I use a third party COM component. So the problem is that the above component has a method, which takes a string and a number of key-value pairs as arguments. I already managed to call that method through JavaScript like that: var srcName srcName = top.cadView.addSource( 'Database', { driver : 'Oracle', host : '10.10.1.123', port : 1234, database : 'someSID', user : 'someuser', password : 'somepass' } ) if ( srcName != '' ) { ... } ... and it worked perfectly well. However I have no idea how to do the same using C#. I tried passing the pairs as Dictionary and Struct/Class but it throws me a "Specified cast is not valid." exception. I also tried using Hashtable like that: Hashtable args = new Hashtable(); args.Add("driver", "Oracle"); args.Add("host", "10.10.1.123"); args.Add("port", 1234); args.Add("database", "someSID"); args.Add("user", "someUser"); args.Add("password", "samePass"); String srcName = axCVCanvas.addSource("Database", args); and although it doesn't throw an exception it still won't do the job, writing me in a log file [ Error] [14:38:33.281] Cad::SourceDB::SourceDB(): missing parameter 'driver' Any help will be appreciated, thanks.
