  • Vertically align UILabel

    - by Ashish Agarwal
    I am trying to vertically align the text in the UILabel view of my app. The problem is that I want the text to be vertically aligned to the top and the size of the label to be 280 x 150. I am only able to achieve one of these 2 things. If I remove the line [myLabel sizeToFit]; then the alignment of the text is alright but the size is messed up. But if I add the above line, then the alignment is messed up but the size is alright. How do I fix this problem. I've added the code below - CGRect labelFrame = CGRectMake(22, 50, 280, 150); UILabel *myLabel = [[UILabel alloc] initWithFrame:labelFrame]; [myLabel setText:finalRecipe]; [myLabel setBackgroundColor: [UIColor lightGrayColor]]; [myLabel setNumberOfLines:0]; [myLabel sizeToFit]; [self.view addSubview:myLabel];

  • Textures loaded with NSOperation are blank

    - by Omega
    So I call this method: -(void)beginExecution { NSOperationQueue *queue = [NSOperationQueue new]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(execute) object:nil]; [queue addOperation:operation]; [operation release]; } Which triggers this: -(void)execute { [[CCSpriteFrameCache sharedSpriteFrameCache]addSpriteFramesWithFile:@"MyTexture.plist"]; loaded = YES; // This tells me whenever loading is done. } However, when I create a sprite and try to use the texture MyTexture.png, the sprite is a blank canvas. Why is that?

  • Generate xml containing animation information from ms ppt 2003/07 file

    - by Ravisha
    I am planning to write an application which has UI from MS ppt.Here is where all the animation will be configured. My application will just read xmls containing animation configuration and run it on a target device(Cannot mention details w.r.t device right now ,apologies for that) Not necessary that i want xmls it self but if there is a way to get animation details directly from the ppt file i will be more than happy.

  • What are some useful SQL statements / usage patterns that should be known by all developers who may

    - by Jian Lin
    What are some useful SQL statements that should be known by all developers who may touch the Back end side of the project? (Update: just like in algorithm, we know there are sorting problems, shuffling problems, and we know some solutions to them. This question is aiming at the same thing). For example, ones I can think of are: Get a list of Employees and their boss. Or one with the employee's salary greater than the boss. (Self-join) Get a list of the most popular Classes registered by students, from the greatest number to the smallest. (Count, group by, order by) Get a list of Classes that are not registered by any students. (Outer join and check whether the match is NULL, or by Get from Classes table, all ClassIDs which are NOT IN (a subquery to get all ClassIDs from the Registrations table)) Are there some SQL statements that should be under the sleeve of all developers that might touch back end data?

  • Injecting relationships in DBIx::Class

    - by Carl
    I have a handful of DBIx::Class::Core objects that model various database tables. For some of those models (those that have a 'queue' column), I have another class inject subs (basically, to 'move' the model object along it's queue states). I'd like to also have that class inject has_many relationships ala class($name)->has_many('queue_history','MySchema::Result::QueueHistory', { 'foreign.record_id'=>'self.id' }, { where => { type => $name }} ); but I can't seem to get the relationships to register properly (keep getting "No Such Relationship" errors - however, when calling the relationship method on the sources provides back the relationship). Any clues as to what's wrong?

  • Displaying Fields (and/instead of Properties) in a PropertyGrid

    - by Jenk
    I'd like to use a PropertyGrid to manipulate the data on some objects, however these objects don't have properties, they have fields. Thus a property grid doesn't display them (high five MS!) Before anyone posts "just use properties": I can't at the moment.. these objects are DTOs and are used to send data to a VB6 Interop dll, thus all the parameters for the method calls are "ref" parameters (high five MS!), and C# won't compile if you use a property instead of a field or variable (high five MS!). No, I am not going to create local variables for every property on any given object. There many, many fields, and many, many test cases that would need updating, as well as the production code it self, and this post/question may be the path of least resistance. :)

  • Stop Rails from unloading a module in development mode

    - by Gareth
    I have a module in my Rails app that lives in /lib module MyModule mattr_accessor :the_variable class << self def setup yield this end end end From my environments/#{RAILS_ENV}.rb file I can then set an environment-specific value for the_variable: MyModule.setup do |my_module_config| my_module_config.the_variable = 42 end This is lovely, and it seems to work (almost) fine. The problem is that in development mode, Rails via ActiveSupport::Dependencies unloads a load of modules, and reloads them in time for the new request. This is usually a great behaviour because it means you don't need to restart your localhost server when you make a code change. However, this also clears out my initialised the_variable variable, and when the next request comes in the initialiser (obviously) isn't run again. The net effect is that subsequent requests end up having MyModule.the_variable set to nil rather than the 42 that I'm looking for. I'm trying to work out how to stop Rails unloading my module at the end of the request, or alternatively find another way to cleanly provide environment specific configuration for my modules. Any ideas? :-/

  • Cocoa - Localized string from NSDate, NSCalendarDate...

    - by SirRatty
    I'm using NSDate to get a string such as "18 Jun 09", with code: NSDate *theDate = [NSDate date]; NSString *dateString = [theDate descriptionWithCalendarFormat:@"%d %b %y" timeZone:nil locale: nil]; This works, but only results in an English output. I need the output to be localized in the user's default language. Does Cocoa (Mac OS X 10.4, 10.5 in this case) provide a facility for this localization or do I have to manually localize for each case of day and & month names my self? (I have provided a locale, but although that does provide a locale-specific ordering of the date, it does not appear to do any localization of day-month names.)

  • Which jQuery/css menu library for working with ASP.NET TreeView or Menu controls.

    - by ProfK
    I'm looking for a good jQuery or CSS, or combo, library to enance my left side menu in an an intranet application. I don't like the 'hover only' expand/collapse style of the ASP.NET Menu control on its own, and I don't like the 'icon-click only' expand/collapse style of the TreeView control on its own. I plan on trying the CSS Control Adapters, to render the menu with some self-respect, i.e. as nested <ul> or <ol> elements instead of the usual orgy of tables. Beyond that, I need something to give a bit of style and menulike behaviour to these nested lists, and I would prefer a jQuery plugin for this. Which should I use?

  • What to read as a good quick review and intro into development process methodologies?

    - by Ivan
    Being mostly self-taught freestyle developer and having no experience of working in teams of professionals in serious software companies, having only a very general idea of how the software development is should really be done, I think I've came to a point, when I begin struggling from lack of order in my work. I think I should get acquainted with professional software development technologies to optimize my own productivity and to extend my choice of work by increasing capabilities to work in teams and bigger companies. What should I begin with? Of course I am googling on this subject right now, but maybe hou have some real experience based recommendations to share?

  • Ttstyledtextlabel does not draw properly when text property is assigned multiple times

    - by user210504
    I have A ttstyledtextlabel in my uitableview cell. It has got some web URLs for images which are being rendered. But since images take some time to download i reload the cell after sometime to render the images if they have been downloaded. The problem I am facing is that during subsequent assignment of text if the size of the label changes, happens when images have been successfully loaded the label does not render properly but rather blanks out. But I see the proper label when is scroll and come back to the cell again. Anyone faced this issue or simply when the following line is executed multiple times, the Styled Label goes blank StyledView.text = [TTStyledText textFromXHTML:[self getStyledText] lineBreaks:YES URLs:YES];

  • RoR model field without validators, has*, delegates, etc

    - by jackr
    How can I declare a field, in the Rails model, when it doesn't have any "has_" relations, or validations, or delegations? I just need to ensure its existence and column width in the schema. Currently, I have no mention of the field in the "schema section" of the model file, but it's referenced in various methods that use it, and this seems to work. However, depending on my exact creation workflow, the underlying database table may be created as t.binary "field_name", :limit => 32 or t.binary "field_name", :limit => 255 This is not a restriction on the value (any binary value is valid, even NULL), only on the table column declaration. As it happens, 32 is enough -- it never receives any larger value, it's only ever written to like this: self.field_name = SecureRandom.random_bytes(32)

  • How to calculate the touch location with convertToWorldSpace?

    - by Paul
    i would like to convert the touch location as a world coordinate in my tile game. With this code, i clicked on the right of the screen (so that my character walks in the tiled game, and the background goes slowly to the left) : - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView: [touch view]]; location = [[CCDirector sharedDirector] convertToGL: location]; CGPoint test = [self convertToWorldSpace:location]; CCLOG(@"test : %.2g", test.x); The test log gives me : 50, 72, 1e+02, 2.6e+02, 4.2e+02, (and then goes down) 3.2e+02, 9.5, -1.9e+02, etc. Does anyone know why? I would like to calculate the "real" coordinate of the touch, so that i know when the character has to keep going (click on the right of its actual position) or if he has to turn and go backwards. (click on the left of its actual position) Thanks for your help

  • C: Recursive function for inverting an int

    - by Jorge
    I had this problem on an exam yesterday. I couldn't resolve it so you can imagine the result... Make a recursive function: int invertint( int num) that will receive an integer and return it but inverted, example: 321 would return as 123 I wrote this: int invertint( int num ) { int rest = num % 10; int div = num / 10; if( div == 0 ) { return( rest ); } return( rest * 10 + invert( div ) ) } Worked for 2 digits numbers but not for 3 digits or more. Since 321 would return 1 * 10 + 23 in the last stage. Thanks a lot! PS: Is there a way to understand these kind of recursion problems in a faster manner or it's up to imagination of one self?

  • What is a good way to quantify C++ knowledge and skill?

    - by LoudNPossiblyRight
    I have only recently started to study (with the hopes of mastering) C++, one because i have started to love it and two because it's a good career/profession move. At the same time i wish to quantify my knowledge and skill so as to set my self apart from those who just throw C/C++ on their resumes and fish. Is there an open, industry and community recognized way of quantifying ones knowledge and skill in C++? I have looked at Brainbench, MS C++ certificates, and other online certification sites which offer to rate you at $50-$200 per test however there doesn't seem to be a standard on how to rate knowledge and skill. It's one thing for MS or Oracle/Sun to have certifications for their products but C++ is a standard, shouldn't there be a standard way or rating one's knowledge and skill there in? Thanks.

  • Can you make a PHP function recursive without repeating it's name?

    - by alex
    It's always bugged me a recursive function needs to name itself, when a instantiated class can use $this and a static method can use self etc. Is there a similar way to do this in a recursive function without naming it again (just to cut down on maintenance)? Obviously I could use call_user_func or the __FUNCTION__ constant but I would prefer something less ugly. Update Thanks for your answers. I might stick to including the function name for simple functions, and make take the other approaches for anything more complicated.

  • iPhone - a question about @property

    - by Roger
    Hi, I am kind of newbie on Objective-C and I was looking at a code, trying to understand a few things, and I come across with this .h file: there was a declaration like that on the @interface section MyVideoClass *contrast_; then below we have @property (nonatomic, retain) MyVideoClass *contrast; @property (nonatomic, retain) FetchClass *fetchMe; The strange part is that the first has an underscrore after the name and the second one, doesn't. The other strange thing is that the guy has a call to these properties like this: FetchClass *fetchOne = [self.fetchMe contrast]; What kind of call is that? This seems pretty insane to me. I simply cannot understand what is going on here, but the code works. pretty insane. Can you guys explain me that? Forgive the stupid question, but I am still learning... thanks

  • Getting Notifications in Background Mode iOS?

    - by Pau Senabre
    I'm trying to get Notifications in Background Mode by running a method every minute to see if there are new notifications. This works great in Active Mode, but I saw for background mode it is restricted to 7 keys. I enabled the Background Mode with the option Background Fetch, but seems like the method is being called but it's not complete. In AppDelegate I'm calling: - (void)applicationDidEnterBackground:(UIApplication *)application { //This has a Timer to execute every minute [self GetNotifications]; //This executes a NSMutableURLRequest *request //giving back the JSON data with the notifications } I would like to do something like Facebook does for Notifications. Any idea how to do this?

  • In c++ is there any Events/delegates/interfaces/notifications! anything?

    - by Bach
    Say i have these classes ViewA and ViewB In objective C using the delegate pattern I could do @protocol ViewBDelegate{ - (void) doSomething(); } then in ViewB interface: id<ViewBDelegate> delegate; then in ViewA implementation i set the delegate: viewB.delegate = self; and now I can call in doSomething from viewB onto any that unknown type delegate. [delegate doSomething]; "C++ How to Program" has been the worse read an can't find simple examples that demonstrates basic design patterns. What i'm looking for in C++ is: events ActionScript and java either delegates or notifications in Objective C anything that allows class A, Class B and Class C to know that ClassX didSomething()!!! thanks

  • How does one validate html that's generated from JS running in the browser?

    - by Henry Rose
    The page in question has very skeletal html sent over the wire to facilitate the building of a complicated UI in javascript. I'm now encountering a strange browser compatibility issue that feels very much like I've got a markup problem somewhere on the page. I've validated the page as it comes across the wire using the W3C tool and ensured there are no issues in that html. I've also tried validating the output of running on the browser console: document.getElementsByTagName('html')[0].outerHTML I find that the output of the above introduces lots of new issues, such as removing the trailing '/' in self closing tags. This added noise is distracting, but it also makes me uneasy about validating this method. How do you validate markup that's rendered client side?
