  • Get a tableview insertRowsAtIndexPaths to accept indexOfObject?

    - by Emil
    Hey. I have a code snippet that looks like this: [tableView beginUpdates]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[array indexOfObject:[array objectAtIndex:indexPath.row]]] withRowAnimation:UITableViewRowAnimationLeft]; [tableView endUpdates]; [tableView reloadData]; It gets executed when a user clicks on an accessory. The first part is only there to provide a smooth animation, and does not really matter, as the tableView is reloaded milliseconds later, but as I said, it's there to provide an animation. It is supposed to move a selected object from its current indexPath to the value from an array at the same indexPath. Obviously, this code does not work, so I just want to know what can be done to fix it? PS: I get a warning when compiling, too. The usual "passing argument 1 of 'arrayWithObject:' makes pointer from integer without a cast..." (line 3)

  • shell script redirect output

    - by Andy
    I have a shell script to monitor process due to preventing the process closed. If the process is closed, that script will restart it. BTW, when the system starts, the crontab will run the script automatically. How can I get the output of the process which started by the shell script? #!/bin/bash PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin export PATH while : do if [ -z "$(ps -ef | grep -v grep | grep 225.0.6.4)" ]; then date +"%m-%d-%y %T" >> /home/andy/log/stream.log echo "225.0.6.4 - 103 not worked and restart process" >> /home/andy/log/stream.log echo "225.0.6.4 - 103 not worked and restart process" /usr/bin/tzap -a 1 -c /home/andy/channels.conf -o - -r -p "D" | /home/andy/ffmpeg -f mpegts -i pipe:0 -c:v libx264 -preset medium -crf 23 -bufsize 3000K -minrate 1200k -maxrate 1200k -pix_fmt yuv420p -g 50 -s 1024x768 -acodec libmp3lame -b:a 128k -ac 2 -ar 44100 -f mpegts udp://225.0.6.4:50000 & fi sleep 1 done

  • Removing all CALayer's sublayers

    - by radex
    Hi. I have trouble with deleting all layer's sublayers. I do this manually, but it's unwanted code clutter. I found many topics about this in google, but no answer. I tried to do something like this: for(CALayer *layer in rootLayer.sublayers) { [layer removeFromSublayer]; } but it didn't work. Also, i tried to clone rootLayer.sublayers into separate NSArray, but result was the same. Any ideas? regards, radex PS. sorry for my English. Edit: I thought it works now, but I was wrong. It works good with CALayers, but it doesn't work with CATextLayers. Any ideas?

  • continuous music on website

    - by Patrick
    Hi all, I'm against it as I'm sure ALL of you are, but my client wants background music on their website. I'm very new to this, so was wondering how should I do that? I know I should use iframes, but what's the actual way of using them? eg: do I just create the home page with 2 frames (one for the music, one for the rest of the website), and then every time the user clicks on a link I can load the usual destination page - or should I update all pages in some way to make sure they are 'frames enabled'? Also, I do I style the frame to make sure it's hidden? thanks, Patrick ps please don't reopen the discussion about why background music is not good - I do know that and personally hate it. But the client is adamant and paying for it so... ;)

  • Microsoft T-SQL to Oracle PL/SQL translation

    - by Michael Prewecki
    I've worked with T-SQL for years but i've just moved to an organisation that is going to require writing some Oracle stuff, probably just simple CRUD operations at least until I find my feet. I'm not going to be migrating databases from one to the other simply interacting with existing Oracle databases from an Application Development perspective. Is there are tool or utility available to easily translate T-SQL into PL/SQL, a keyword mapper is the sort of thing I'm looking for. P.S. I'm too lazy to RTFM, besides it's not going to be a big part of my role so I just want something to get me up to speed a little faster.

  • Adding scope variable to an constructor

    - by Lupus
    I'm trying to create a class like architecture on javascript but stuck on a point. Here is the code: var make = function(args) { var priv = args.priv, cons = args.cons, pub = args.pub; return function(consParams) { var priv = priv, cons = args.cons; cons.prototype.constructor = cons; cons.prototype = $.extend({}, pub); if (!$.isFunction(cons)) { throw new Hata(100001); } return new cons(consParams); } }; I'm trying to add the priv variable on the returned function objects's scope and object scope of the cons.prototype but I could not make it; Here is the usage of the make object: var myClass = make({ cons: function() { alert(this.acik); }, pub: { acik: 'acik' }, priv: { gizli: 'gizli' } }) myObj = myClass(); PS: Please forgive my english...

  • How can I use Moose with Test::Class?

    - by rassie
    I'm currently refactoring a test suite built up by a colleague and would like to use Test::Class[::Most] while doing so. As I started I figured out I could really use a couple of Moose roles to decouple code a little bit. However, it seems it's not quite possible -- I'm getting error messages like this one: Prototype mismatch: sub My::Test::Class::Base::blessed: none vs ($) at /usr/lib/perl5/vendor_perl/5.8.8/Sub/Exporter.pm line 896 So the question is: can I use Moose together with Test::Class and if so, how? PS: The code goes like this: package My::Test::Class::Base; use Moose; use Test::Class::Most; with 'My::Cool::Role'; has attr => ( ... );

  • Control within ascx is null when ascx is added from codebehind

    - by Snoop Dogg
    I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null. ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked. rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here http://techlipse.net/test/ledart Thanks a lot in advance...

  • Why does forward declaration not work with classes?

    - by eSKay
    int main() { B bb; //does not compile (neither does class B bb;) C cc; //does not compile struct t tt; //compiles class B {}; struct s { struct t * pt; }; //compiles struct t { struct s * ps; }; return 0; } class C {}; I just modified the example given here. Why is that the struct forward declarations work but not the class forward declarations? Does it have something to do with the namespaces - tag namespace and typedef namespace? I know that the structure definitions without typedefs go to tag namespace. Structures are just classes with all public members. So, I expect them to behave similarly.

  • Migrate existing ROR app to GAE

    - by zengr
    I have managed to run a basic rails app1 on App Engine using: http://gist.github.com/268192 So, on my basic app2, I install CE, which works fine on local machine. (communityengine.org) But, when I follow the same steps on my actual app2, where community_engine plugin is installed and all the gems are frozen, the app engine installer script asks for to over write various files like boot.rb, routes.rb, which I don't allow. So, as expected, when I publish the rails + ce app to GAE, it's not published and it also screws the local installation of CE on app2. So, the problem is obvious, CE uses ActiveRecord, and GAE uses DataMapper. So, my question can also be rephrased as: Can we migrate an existing ROR App using Active Record to GAE which uses DataMapper? PS: This is my first project on ROR and GAE.

  • Custom view in ListView disappears while scrolling in Android

    - by troorl
    Hi. I wrote a simple custom view for rows in ListView. It works fine, but when I try to scroll the list, I see only white rows without content. And when scrolling is over, rows continue to show again. This is how I draw a custom view: @Override protected void onDraw(Canvas canvas) { if(poster != null) { canvas.drawBitmap(poster, padding, padding, paint); } canvas.drawText(title, 55 + padding, 16 + padding, paint); } Maybe I missed something? P.S. This is short screencast (400kb) http://dl.dropbox.com/u/190203/test.mpeg

  • Using java classes in Grails

    - by RN
    I have a Java\Spring\Hibernate application - complete with domain classes which are basically Hibernate POJOs There is a piece of functionality that I think can be written well in Grails. I wish to reuse the domain classes that I have created in the main Java app What is the best way to do so ? Should I write new domain classes extending the Java classes ? this sounds tacky Or Can I 'generate' controllers off the Java domain classes ? What are the best practices around reusing Java domain objects in Grails\Groovy I am sure there must be others writing some pieces in grails\groovy If you know about a tutorial which talks about such an integration- that would be awesome !!! PS: I am quite a newbie in grails-groovy so may be missing the obvious. Thanks !!!

  • Pros and cons of programmatically enforcing foreign key than in database

    - by Jeffrey
    It is causing so much trouble in terms of development just by letting database enforcing foreign key. Especially during unit test I can’t drop table due to foreign key constrains, I need to create table in such an order that foreign key constrain warning won’t get triggered. In reality I don’t see too much point of letting database enforcing the foreign key constrains. If the application has been properly designed there should not be any manual database manipulation other than select queries. I just want to make sure that I am not digging myself into a hole by not having foreign key constrains in database and leaving it solely to the application’s responsibility. Am I missing anything? P.S. my real unit tests (not those that use mocking) will drop existing tables if the structure of underlying domain object has been modified.

  • Looking for an automated logging tool/library for .NET!

    - by tsocks
    Hello, I'm looking for an library/tool for .NET that logs almost everything that happens in my C# application (Windows Form). The problem is that I'm delivering an application to a client (Windows XP) and after doing some task, that classic Microsoft error window appears: "ApplicationName has encountered a problem and needs to close. We are sorry for the inconvenience" I'm currently handling my application exceptions, but this is something external and I can't get anything from that error, so I would like any automated library that helps me with that. It would work if it logs each line of code executed, orr just log what line was executing before that error appeared, or something that could give me more info about that error. Thank you! P.S: It's a multithreaded application, and have to Timer controls (one for watching a folder every 5secs, and another for watching thread list...). I'm using Windows 7 here and everything seems to work ok.

  • How To: Referencing LAPACK library from FORTRAN 95 in Cygwin

    - by cholmgreen
    I have a FORTRAN 95 program that needs to make some calls to the LAPACK library. I recently found out that Cygwin because it can install LAPACK as an extra option. Well, LAPACK exists in the /lib/lapack/ directory as "cyglapack.dll". Having only a very informal training in Fortran programming, I have no idea how to reference a .dll library as opposed to a .mod module. Any suggestions or directions to articles answering my question are GREATLY appreciated! (P.S. I did search first.. I don't think I know the proper terms to get a useful article.)

  • Situations to prefer Apache Lucene over Solr?

    - by Karussell
    There are several advantages to use Solr (out-of-the-box facetting search, grouping, replication, http administration vs. luke, ...). Even if I embed a search-functionality in my Java application I could use SolrJ to avoid the HTTP trade-off when using Solr. So, when would you recommend to use "pure-Lucene"? Does it have a better performance or requires less RAM? Is it better unit-testable? PS: I am aware of this question.

  • Flex TileList control, image loading issue

    - by ckenan
    I have a flex 3 TileList in wich a load several image (employee's headshot pictures). The image I'm loading in the TileList are stored in a DataBase (I use the ByteArray class and a Base 64 encoding to store the images in the DB). When I load the images in the TileList from the DB, there is no problem they are displayed correctly, but when I scroll down in the TileList and scroll up again, the position of the images is changing, so for example the image in first position can be now in the 3rd and so on .... Does somebody knows how to fix that ? Thanks in advance! PS : Here is the code of the ItemRenderer for the TileList private function init():void { img.load(data.imageData); } ]]

  • Why is C# suddenly so popular?

    - by leeand00
    Why is C# suddenly so popular? There's been like a repeat explosion in the blogs lately about it; It reminds me of the earlier part of this decade when all of those frameworks for Java came out like Spring, JSF, Hibernate, Struts, Struts2, Tapestry etc... I've actually been thinking about learning C#, and it seems to contain a lot of qualities that it has gotten from Java (aside from it being completely cross-platform) But, it almost seems like a step backwards to me...its not totally multi-platform, a language that's run by a corporation rather than a community... (But, knowing this isn't the case, I've come here to find out why it isn't...) P.S. And yes, I am aware of the Mono project so that you can run it on Linux, but isn't it always behind the curve? A new version of Java would be supported on all the platforms.

  • dojo datagrid will make the page "jump" when sorting is changed

    - by Select0r
    Hi, I have a Dojo Datagrid in one of my pages (which contains more content) and the following problem occurs: As soon as I click on a column header to change the sorting, the page will jump up as if I clicked on some HTML-anchor. Funny enough, the page jump will make the grid show only the first two rows after it jumped, instead of (e.g.) have the grid start at the top of the page after the jump, which is the expected behaviour if an anchor is used. The problem occurs in different browsers (tested: Firefox 3.6, Opera 10, IE6), so I guess it might be a Dojo-problem/-bug. Any ideas to make this annoying behaviour stop? Greetings, Select0r PS: this seems to describe a similar problem, only for JQuery (and unfortunately without a solution, too)

  • PHP SoapClient: Problems with Distributed WSDL File

    - by Dave
    Hello, I have a problem using a distributed WSDL File ( scheme / other definitions are declared outside the actual wsdl) with php's SoapClient. This is the Fault Message I get: SOAP-ERROR: Parsing WSDL: 'getSomeInfo' already defined. After some googling , it seems to be a bug inside php as someone else discovered exactly the same problem: http://bugs.php.net/bug.php?id=45282 Has there been any bug fix(es)? Any solution to work around this bug? PS: I think posting a code snippet is senseless, since the invocation of the SoapClient ctor using just the WSDL is the only that fails. Thank you in advance, Dave

  • [JS] XMLHttpRequest problem

    - by mcco
    I am trying to do "POST" with XMLHttpRequest in a firefox extension, and after that I try to get the "Location" header and open it in a new tab. For some reason, the XMLHttpRequest doesn't contain a location header. My code function web(url,request) { var http = new XMLHttpRequest(); http.open('POST',url,true); http.setRequestHeader('Content-Type','application/x-www-form-urlencoded'); http.onreadystatechange=function() { if(http.readyState == 2) { alert(http.getResponseHeader("Location")); } } http.send(request); } Also, if I change the alert to getAllResponseHeaders() to see all headers, I just don't see the location header there. If I try to spy on the request of the original site with Firebug, it does show me the location header in the response. Please help me resolve my issues. Thanks :) P.S. I'm also unable to open a link in new tab using window.open(url, this.window.title);, but as that's not directly related to the rest of this I'll post a separate question to ask about it.

  • Virtual dedicated surver repetitive draining RAM, OOM constantly

    - by Deerly
    My linux (fedora red hat 7) virtual dedicated server has been experiencing OOM multiple times a day for the past several days. I thought the issue was with spamd/spamassassin but after disabling this the errors remains.

Any help or suggestions on zeroing in on the source of the drain would be much appreciated! Thanks!

  • Transpose a Collection

    - by Joseph Melettukunnel
    Hello, I've a list of different sizes of a T-Shirt, e.g. S, M, L. Since this might change for T-Shirts (sometimes we just have e.g. M, L), we load this into a List sizes. Since most DataGrids (xamDataGrid, WPF Toolkit DataGrid) need Properties for binding to the Columns, I'd like to transpose somehow my data. Does anyone have an idea how to do this? E.g. Instead of having List where Size { string sizeName, int available, int defect, int ordered} Avail. Defect Ordered [S] 1 2 3 [M] 1 2 3 [L] 1 2 3 I want an Object which has the Properties S, M, L containing the Values like this: [S] [M] [L] Avail. 1 2 3 Defect 1 2 3 Ordered 1 2 3 The problem here is that I don't know how many sizes will be available for the tshirt, it might be 3, 4, or 10. Thanks for any help Cheers PS: Here is a mockup of how the final grid should look like http://img39.imageshack.us/img39/9161/multirowspangridfixedel.png
