  • Float right is making background-color disappear in IE while hovering.

    - by janoChen
    Everything works OK in this language menu: http://alexchen.co.nr/beta (top right of the page). But I want the li elements to float to the right. But when I add float:right to #lang li a the background-color stop working while hovering when I hover them in IE7. #lang { float: right; padding: 50px 25px 0 0px; margin: 0 0 0 0px; width: 295px; } #lang li { font-size: 10px; width: 325px; /*ie hack */ } #lang li a { color: #FFF; padding: 5px 25px 5px 249px; line-height: 220%; } #lang li a:hover { color: #444; background-color: #FFF; } #lang li.current a { color: #444; background-color: #FFF; cursor: default; }

  • android localization: Is it a good practice to have only needed resource to put in localized folder?

    - by MobileDev123
    Hi, My application has 4 languages in it. However only one module needs to be localized out of 5, This module has 4 layout files and some images, remaining files can be there in default layout folder and drawable folders. My question is : is it good practice to put only needed files in localization folders, if I leave other files in its respective folders and don't copy them in translation folders, does my application throw NullPointerException when my application runs in other language? and Does android market have any size limit? (Also being a BB developer,AFAIK they do not allow OTA, if the application size grows more than 3 mb) [In case i need to copy the layout and image files]. Note about NullPointerException : it throws in string if you omit some string in localization and application runs in that particular locale. Thanks

  • Extension methods on a static object

    - by Max Malygin
    I know (or so I hear) that writing extension methods for a single stand alone .net class (not an implementation of IEnumerable) is potential code smell. However, for the sake of making the life easier I need to attach a method to the ConfigurationManager class in asp.net. It's a static object so this won't work: public static List<string> GetSupportedDomains(this ConfigurationManager manager) { //the manager needs to be static. } So the question is - is it possible to write an extension method for a static class in .net?

  • overriding callbacks avoiding attribute pollution

    - by pygabriel
    I've a class that has some callbacks and its own interface, something like: class Service: def __init__(self): connect("service_resolved", self.service_resolved) def service_resolved(self, a,b c): ''' This function is called when it's triggered service resolved signal and has a lot of parameters''' the connect function is for example the gtkwidget.connect, but I want that this connection is something more general, so I've decided to use a "twisted like" approach: class MyService(Service): def my_on_service_resolved(self, little_param): ''' it's a decorated version of srvice_resolved ''' def service_resolved(self,a,b,c): super(MyService,self).service_resolved(a,b,c) little_param = "something that's obtained from a,b,c" self.my_on_service_resolved(little_param) So I can use MyService by overriding my_on_service_resolved. The problem is the "attributes" pollution. In the real implementation, Service has some attributes that can accidentally be overriden in MyService and those who subclass MyService. How can I avoid attribute pollution? What I've thought is a "wrapper" like approach but I don't know if it's a good solution: class WrapperService(): def __init__(self): self._service = service_resolved # how to override self._service.service_resolved callback? def my_on_service_resolved(self,param): ''' '''

  • Determining child count of path

    - by sqlnewbie
    I have a table whose 'path' column has values and I would like to update the table's 'child_count' column so that I get the following output. path | child_count --------+------------- | 5 /a | 3 /a/a | 0 /a/b | 1 /a/b/c | 0 /b | 0 My present solution - which is way too inefficient - uses a stored procedure as follows: CREATE FUNCTION child_count() RETURNS VOID AS $$ DECLARE parent VARCHAR; BEGIN FOR parent IN SELECT path FROM my_table LOOP DECLARE tokens VARCHAR[] := REGEXP_SPLIT_TO_ARRAY(parent, '/'); str VARCHAR := ''; BEGIN FOR i IN 2..ARRAY_LENGTH(tokens, 1) LOOP UPDATE my_table SET child_count = child_count + 1 WHERE path = str; str := str || '/' || tokens[i]; END LOOP; END; END LOOP; END; $$ LANGUAGE plpgsql; Anyone knows of a single UPDATE statement that does the same thing?

  • Print number series in java

    - by user1898282
    I have to print the series shown below in java: ***1*** **2*2** *3*3*3* 4*4*4*4 My current implementation is: public static void printSeries(int number,int numberOfCharsinEachLine){ String s="*"; for(int i=1;i<=number;i++){ int countOfs=(numberOfCharsinEachLine-(i)-(i-1))/2; if(countOfs<0){ System.out.println("Can't be done"); break; } for(int j=0;j<countOfs;j++){ System.out.print(s); } System.out.print(i); for(int k=1;k<i;k++){ System.out.print(s); System.out.print(i); } for(int j=0;j<countOfs;j++){ System.out.print(s); } System.out.println(); } } But there are lot of for loops, so I'm wondering whether this can be done in a better way or not?

  • What's the deal with a leading underscore in PHP class methods?

    - by nocash
    While looking over various PHP libraries I've noticed that a lot of people choose to prefix some class methods with a single underscore, such as public function _foo() ...instead of... public function foo() I realize that ultimately this comes down to personal preference, but I was wondering if anyone had some insight into where this habit comes from. My thought is that it's probably being carried over from PHP 4, before class methods could be marked as protected or private, as a way of implying "do not call this method from outside the class". However, it also occurred to me that maybe it originates somewhere (a language) I'm not familiar with or that there may be good reasoning behind it that I would benefit from knowing. Any thoughts, insights and/or opinions would be appreciated.

  • WorkFlow and WCF dynamically launching WorkFlows

    - by Raj73
    I have a WF which will be hosted on WCF . The service Contract will contain a single operation containing two parameters. Parameter1 will be a string and will contain the name of the workflow to invoke and parameter two will contain the input for the invoked Work Flow. All operations will take the same parameter. All the operations will return the same return value. I have created the service implementation and I would like to depending on the value of parameter1 start executing the appropriate workflow and return the value (There can be number of workflow classes say Operation1, Operation2...which will be the passed in as the value in Parameter1). How can I instantiate different workflow classes and pass parameters and get the return values from them which I should then pass back to the calling Client. (Also Should I be using ReceiveActivities in all of my Launchable WorkFlow Classes ? ) Any code samples or pointers would help

  • C# Dataset usage necessary before passing to GridView datasource?

    - by Goober
    Scenario Lets say for example I have a series of events that fire continually every half second presenting me with an object containing some bits of information. There are always between 10 and 15 objects that are being updated constantly. Since these bits of information are changing continually I want to display them in a GridView. When I do so, I want the user to see the data displayed in the gridview and actually be updated as opposed to just a continually extending list being printed and incrementing (like writeline on the console). Question Is the best way to achieve this to map my objects to a dataset and have the dataset mapped to the gridview? Thoughts Will this allow the gridview to just be "UPDATED" as opposed to being added to? Any implementation suggestions would be greatly appreciated. EDIT: it MUST be windows forms (I use DevExpress too)

  • What is the best way to prevent a webpage coded completely in HTML (no PHP or any server side langua

    - by racl101
    I thought by placing these two lines that it would prevent the page from being cached but this is not the case between the head tags: <meta http-equiv="pragma" content="no-cache" /> <meta http-equiv="cache-control" content="no-cache" /> As already mentioned this is on server that doesn't support PHP (or any server side language, well, that's not true, it has cgi-bin folder that supports perl scripts but I don't know perl and have no time to engage in it.) What else could I do to prevent the page from caching? It caches on Firefox and IE (and not so much in Chrome or Safari.)

  • is there a limit of merge tables with Mysql ?

    - by sysko
    I'm working on a database with mysql 5.0 for an open source project it's used to stored sentences in specific languages and their translations in other languages I used to have a big table "sentences" and "sentences_translations" (use to join sentences to sentences) table but has we have now near one million entries, this begin to be a bit slow, moreover, most of request are made using a "where lang =" so I've decided to create a table by language sentences_LANGUAGECODE and sentences_translation_LANGSOURCE_LANGTARGET and to create merge table like this sentences_ENG_OTHERS which merge sentences_ENG_ARA sentences_ENG_DEU etc... when we want to have the translations in all languages of an english sentence sentences_OTHERS_ENG when we want to have only the english translations of some sentences I've created a script to create all these tables (they're around 31 languages so more than 60 merge table), I've tested, that works really great a request which use to take 160ms now take only 30 :) but I discover that all my merge table after the 15th use to have "NULL" as type of storage engine instead of MRG_MYISAM, and if delete one, then I can create an others, using FLUSH table between each creation also allow me to create more merge tables so is this a limitation from mysql ? can we override it ? thanks for your answers

  • Objective-C: Cannot Change Value of Instance Variable Inside a Function

    - by user262325
    Hello everyone, I cannot change the value of an instance variable inside a function. I have defined a class: // info.h #import <Foundation/Foundation.h> @interface NSMyObject : NSObject { NSInteger i; } -(void) setI:(NSInteger)v; @end #import "info.h" @implementation NSMyObject -(void) setI:(NSInteger)v ; { i=v; } - (void)dealloc { [super dealloc]; } @end I call a function 'myFunction' with parameter temObj which is a NSMyObject instance. myFunction(temObj);//temObj is NSMyObject In the function, I can change the value of the instance variable of parameter obj. -(void)myFunction:(NSMyObject*) obj; { [obj setI:0]; } ... expecting this to change the content of temObj. But when I check the results of operation on obj in function myFunction the value of temObj.i has not changed. Welcome any comment Thanks

  • Why won't my movie play using MPMoviePlayerController?

    - by Nosrettap
    I'm trying to get a basic movie to play in an iPhone app; however, I can't seem to get it to work. Here's my entire code: #import <MediaPlayer/MediaPlayer.h> #import "ViewController.h" @implementation ViewController - (IBAction)playMoviePressed:(id)sender { NSURL *url = [NSURL URLWithString:@"http://www.ebookfrenzy.com/ios_book/movie/movie.mov"]; MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer]; moviePlayer.controlStyle = MPMovieControlStyleDefault; moviePlayer.shouldAutoplay = YES; [self.view addSubview:moviePlayer.view]; [moviePlayer setFullscreen:YES animated:YES]; [moviePlayer prepareToPlay]; [moviePlayer play]; } @end I have one button on screen that calls playMoviePressed when it is tapped. I know that this method is getting called. I have also tried this with .mov and .mp4 local files that I have dragged into xcode.

  • Likelihood of IOError during print vs. write

    - by jkasnicki
    I recently encountered an IOError writing to a file on NFS. There wasn't a disk space or permission issue, so I assume this was just a network hiccup. The obvious solution is to wrap the write in a try-except, but I was curious whether the implementation of print and write in Python make either of the following more or less likely to raise IOError: f_print = open('print.txt', 'w') print >>f_print, 'test_print' f_print.close() vs. f_write = open('write.txt', 'w') f_write.write('test_write\n') f_write.close() (If it matters, specifically in Python 2.4 on Linux).

  • Saving substrings using Regular Expressions

    - by user362971
    I'm new to regular expressions in Java (or any language, for that matter) and I'm wanting to do a find using them. The tricky part that I don't understand how to do is replace something inside the string that matches. For example, if the line I'm looking for is Person item6 [can {item thing [wrap]}] I'm able to write a regex that finds that line, but finding what the word "thing" is (as it may differ among different lines) is my problem. I may want to either replace that word with something else or save it in a variable for later. Is there any easy way to do this using Java's regex engine?

  • .BAT Switches Parsing

    - by giiYanJ
    Erm.. I'm working with a switches parsing in BAT files, which goes like this: <commands> -a -b -x -y -z -u abc ...... The user may input a lot of switch, or none. So I used looped shift to make parsing infinite switches possible: :loop IF "%1"=="-a" ... SHIFT GOTO loop But when the script ends, I always get cmd executing the switches and showing up error like '-n' is not recognized as an internal... So, someone got any idea? Thanks a lot... P/S: Make solution sticks with BAT script if possible as using other language may cause dependencies problem as this script is aimed on ANY computer with Windows. Finally, thanks again =) EDIT: Tried shf301 suggestion, i found out that I used DEL %0 to delete itself but it seems the %0 is shifted into the arguments because of the SHIFT command.

  • Working with Japanese filenames in PHP 5.3 and Windows Vista?

    - by Jon
    I'm currently trying to write a simple script that looks in a folder, and returns a list of all the file names in an RSS feed. However I've hit a major wall... Whenever I try to read filenames with Japanese characters in them, it shows them as ?'s. I've tried the solutions mentioned here: http://stackoverflow.com/questions/482342/php-readdir-problem-with-japanese-language-file-name - however they do not work for some reason, even with: header('Content-Type: text/html; charset=UTF-8'); setlocale(LC_ALL, 'en_US.UTF8'); mb_internal_encoding("UTF-8"); At the top (Exporting as plain text until I can sort this out). What can I do? I need this to work and I don't have much time.

  • Xcode can't find imported header files

    - by solerous
    I've used other IDE's in the past but am new to Xcode. I'm trying to bring in a bunch of C code from an open source project. I've imported them into a new Group and the .c files all show up under Implementation Files and the full list of files shows up in the Groups/Files group as well as my project directory in the finder. When I try to include or import one of these header files, code completion even works so I know Xcode is seeing them. But then when I go to build it says "no such file or directory". How can I get these files to import into my code?

  • Get top 'n' records by report_id

    - by Skudd
    I have a simple view in my MSSQL database. It consists of the following fields: report_id INT ym VARCHAR -- YYYY-MM keyword VARCHAR(MAX) visits INT I can easily get the top 10 keyword hits with the following query: SELECT TOP 10 * FROM top_keywords WHERE ym BETWEEN '2010-05' AND '2010-05' ORDER BY visits DESC Now where it gets tricky is where I have to get the top 10 records for each report_id in the given date range (ym BETWEEN @start_date AND @end_date). How would I go about getting the top 10 for each report_id? I've stumbled across suggestions involving the use of ROW_NUMBER() and RANK(), but have been vastly unsuccessful in their implementation.

  • Accessing object's method within string

    - by Wild One
    Recently I was reading php documentation and found interesting note in string section: Functions, method calls, static class variables, and class constants inside {$} work since PHP 5. However, the value accessed will be interpreted as the name of a variable in the scope in which the string is defined. Using single curly braces ({}) will not work for accessing the return values of functions or methods or the values of class constants or static class variables. See www.php.net/manual/en/language.types.string.php It says, that I can't use curly syntax to get value returned by object's method call. Is it a mistake in manual or I misunderstood it, because I tried the following code and it works just fine: <?php class HelloWorld { public static function hello() { echo 'hello'; } } $a = new HelloWorld(); echo "{$a->hello()} world";

  • Obj-C memory management for an NSView * instance variable

    - by massimoperi
    My custom view has a subview as an instance variable. Here is a sample interface: @interface MyCustomView : NSView { NSView *aSubview; } @end Then, in the .m file, I initialize aSubView and add it to the custom view. - (id)init { self = [super initWithFrame:CGRectMakeFrame(0.0, 0.0, 320.0, 480.0); if (self) { aSubview = [[NSView alloc] initWithFrame(0.0, 0.0, 100.0, 100.0); [self addSubview:aSubview]; } return self; } Where should I release aSubView? In the -dealloc method? - (void)dealloc { [aSubView release]; [super dealloc]; } Or directly after adding it to the custom view in the -init method? - (id)init { [...] [self addSubview:aSubview]; [aSubview release]; [...] } Which one is the best implementation?

  • Class decorator to declare static member (e.g., for log4net)?

    - by Ken
    I'm using log4net, and we have a lot of this in our code: public class Foo { private static readonly ILog log = LogManager.GetLogger(typeof(Foo)); .... } One downside is that it means we're pasting this 10-word section all over, and every now and then somebody forgets to change the class name. The log4net FAQ also mentions this alternative possibility, which is even more verbose: public class Foo { private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); ... } Is it possible to write a decorator to define this? I'd really like to say simply: [LogMe] // or perhaps: [LogMe("log")] public class Foo { ... } I've done similar things in other languages, but never a statically-compiled language like C#. Can I define class members from a decorator?
