  • model view controller question

    - by songBong
    Hi, I've been working on my iphone game recently and came across a forked road when deciding the design of my various classes. So far I've adhered to the MVC pattern but the following situation had me confused: I have 4 buttons displayed visually. Each button though consists of a container UIView (which I've subclassed) and 2 UIButtons (also subclassed) as subviews. When you press a button, it does the flip effect plus other stuff. The user input is using target-action from my container UIView to my controller. This part is ok, the following part is the debatable part: So I've subclassed the container view as well as the UIButtons and I need to add more data/methods (somewhere) to do more things. Putting data that needs to be serialized and non-rendering related code in the view classes seems to break the MVC design but at the moment, it makes the most sense to me to put it there. It's almost like my subclassed views are their own little MVC's and it seems neat. Separating out the data/methods from the view to my main controller in this case seems unnecessary and a more work. How should I be doing it? Thanks heaps.

  • Question about Intent, android

    - by Kaustubh
    I am confused, and need to get my concepts straight. After executing the last statement, which function is called, in MapsActivity? is it onResume? and under which function (onResume()?) should i put getExtra()? Log.i("onMenuAnimate", "Attempting to animate to:"); Intent intent = new Intent(SearchDB.this, MapsActivity.class); intent.putExtra("com.gpsdroid.SearchDB.Lat", nameLatitude.getText()); intent.putExtra("com.gpsdroid.SearchDB.Long", nameLatitude.getText()); SearchDB.this.startActivity(intent);

  • Ruby Gem Install question + answer(on windows vista Home Basic environment)

    - by Vamsi
    Recently I am having problems with installing rcov gem on my windows (vista Home Basic environment), so after googling I found one solution and that is gem install rcov -v 0.8.1.1.0 #version that installs without errors gem update rcov #update to the latest version, in my case rcov-0.8.1.2.0-x86-mswin32 But this solution didn't worked on my colleague's system (windows xp) and after that we came to know about RubyInstaller devkit for winddows But that dev kit is not working on my vista, when I tried gem install rcov in my command prompt, it game me this error, C:\Users\Vamsi>gem install rcov Building native extensions. This could take a while... ERROR: Error installing rcov: ERROR: Failed to build gem native extension.ERROR: Failed to build gem native extension. D:/Spritle/Programs/Ruby/bin/ruby.exe extconf.rb creating Makefile nmake 'nmake' is not recognized as an internal or external command, operable program or batch file. Gem files will remain installed in D:/Spritle/Programs/Ruby/lib/ruby/gems/1.8/ge ms/rcov-0.9.8 for inspection. Results logged to D:/Spritle/Programs/Ruby/lib/ruby/gems/1.8/gems/rcov-0.9.8/ext /rcovrt/gem_make.out So after that my colleague tried to install nmake as well but it was throwing some other error. Can some one suggest a better solution for solving this problems for all windows environments? I am aware of cygwin for windows but I am not sure that is an 100% solution either.

    I have a drupal site with clean urls, the pages load correctly, but then the URL is rewritten, which I really don't to happen.

  • a facebook app question

    - by Robert
    I have written a small app and put it on facebook. I got an application ID and secret. Then I wrote the following script to access my app (just as told on the facebook page). <?php require './src/facebook.php'; $facebook = new Facebook(array( 'appId' => 'xxxx', 'secret' => 'xxxx', 'cookie' => true, // enable optional cookie support )); try { $me = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); } if ($facebook->getSession()) { echo '<a href="' . $facebook->getLogoutUrl() . '">Logout</a>'; } else { echo '<a href="' . $facebook->getLoginUrl() . '">Login</a>'; } ?> Then I started running this script. It prompted me with the login link, then took me to the facebook login page. However, after I enter my facebook login details, I get this error page: Error. API Error Code: 100 API Error Description: Invalid parameter Error Message: next is not owned by the application. Could anyone help me a little bit please, I am really confused here about what's going on.

  • Question about migrating from ASP .NET User Controls to .NET 3.5 Master Page technology

    - by Jim McFetridge
    When migrating from an ASP .NET user control -based page with a header, footer, and menu to a Master Page using the same HTML mark-up, is it normal for CSS or javascript behaviors to change slightly? In particular, the submenu bar text now appears run together (which looks like a CSS symptom) and the graphics on the line above it appear to have an incorrect z-order. (The menu operation is javascript-based.) (I tried to paste images here but couldn't.) Also, the site is very large and we've not been given permission to redo the menu for the entire site. This is a forward-only migration. (Because I know that someone will ask.) Assuming that there are no changes in scope, what are the things that I should check? Thanks! Jim

  • F# performance question: what is the compiler doing?

    - by Stephen Swensen
    Referencing this code: http://stackoverflow.com/questions/2840714/f-static-member-type-constraints/2842037#2842037 Why is, for example, [1L..100000L] |> List.map (fun n -> factorize gL n) significantly slower than [1L..100000L] |> List.map (fun n -> factorize (G_of 1L) n) By looking at Reflector, I can see that the compiler is treating each of these in very different ways, but there is too much going on for me to decipher the essential difference. Naively I assumed the former would perform better than the later because gL is precomputed whereas G_of 1L has to be computed 100,000 times (at least it appears that way).

  • iPad UISPlitViewController question

    - by saikamesh
    Hi, It is mentioned in the Apple's documentation that if we use UISPlitViewController in our app, then that should be the root view controller. In our iPone app we are showing splash screen for some seconds till the loading of the app finishes. Once it is loaded the home screen needs to be displayed in a SplitViewController. If we use SplitViewController as the root view. How will we show the splash screen which is displayed in a single view where as SplitVieController displays two ViewControllers. Please explain me the how this can be done.

  • Zip Code Radius Search question...

    - by KnockKnockWhosThere
    I'm wondering if it's possible to find all points by longitude and latitude within X radius of one point? So, if I provide a latitude/longitude of -76.0000, 38.0000, is it possible to simply find all the possible coordinates within (for example) a 10 mile radius of that? I know that there's a way to calculate the distance between two points, which is why I'm not clear as to whether this is possible... Because, it seems like you need to know the center coordinates (-76 and 38 in this case) as well as the coordinates of every other point in order to determine whether it falls within the specified radius... Is that right?

  • objective C architecture question

    - by thekevinscott
    Hey folks, I'm currently teaching myself objective C. I've gone through the tutorials, but I find I learn best when slogging through a project of my own, so I've embarked on making a backgammon app. Now that I'm partway in, I'm realizing there's some overall architecture things I just don't understand. I've established a "player" class, a "piece" class, and a "board" class. A piece theoretically belongs to both a player and the board. For instance, a player has a color, and every turn makes a move; so the player owns his pieces. At the same time, when moving a piece, it has to check whether it's a valid move, whether there are pieces on the board, etc. From my reading it seems like it's frowned upon to reach across classes. For instance, when a player makes a move, where should the function live that moves the piece? Should it exist on board? This would be my instinct, as the board should decide whether a move is valid or not; but the piece needs to initialize that query, as its the one being moved, no? Any info to help a noob would be super appreciated. Thanks guys!

  • Symfony + JQueryUI Tabs navigation menu question

    - by Andy Poquette
    I'm trying to use the tabs purely as a navigational menu, loading my pages in the tabs, but being able to bookmark said tabs, and have the address bar correspond with the action I'm executing. So here is my simple nav partial: <div id='tabs'> <ul> <li id='home'><a href="<?php echo url_for('post/index') ?>" title="Home">Home</a></li> <li id='test'><a href="<?php echo url_for('post/test') ?>" title="Test">Test</a></li> </ul> </div> And the simple tabs intializer: $(document).ready(function() { $('#tabs').tabs({spinner: '' }); }); My layout just displays $sf_content. I want to display the content for the action I'm executing (currently home or test) in the tab, via ajax, and have the tab be bookmarkable. I've googled this like 4000 times and I can't find an example of what I'm trying to do. If anyone has a resource they know of, I can look it up, or if you can help, I would greatly appreciate it. Thank you in advance.

    Is there any essential difference between this code: ThreadStart starter = new ThreadStart(SomeMethod); starter.Invoke(); and this? ThreadStart starter = new ThreadStart(SomeMethod); Thread th = new Thread(starter); th.Start(); Or does the first invoke the method on the current thread while the second invokes it on a new thread?

  • Understanding CSRF - Simple Question

    - by byronh
    I know this might make me seem like an idiot, I've read everything there is to read about CSRF and I still don't understand how using a 'challenge token' would add any sort of prevention. Please help me clarify the basic concept, none of the articles and posts here on SO I read seemed to really explicitly state what value you're comparing with what. From OWASP: In general, developers need only generate this token once for the current session. After initial generation of this token, the value is stored in the session and is utilized for each subsequent request until the session expires. If I understand the process correctly, this is what happens. I log in at http://example.com and a session/cookie is created containing this random token. Then, every form includes a hidden input also containing this random value from the session which is compared with the session/cookie upon form submission. But what does that accomplish? Aren't you just taking session data, putting it in the page, and then comparing it with the exact same session data? Seems like circular reasoning. These articles keep talking about following the "same-origin policy" but that makes no sense, because all CSRF attacks ARE of the same origin as the user, just tricking the user into doing actions he/she didn't intend. Is there any alternative other than appending the token to every single URL as a query string? Seems very ugly and impractical, and makes bookmarking harder for the user.

"force" setBounds for some strange reason. Container pane = window.getContentPane(); JPanel calendarPanel = new JPanel(); pane.add(calendarPanel); calendarPanel.setBounds(0,0, 320, 335); note that window is of JFrame.
