  • Application crash when using an NSTimer and pushViewController

    - by Cesar
    I'm using an NSTimer to implement a 3 seconds splash screen. If a don't use a timer the view it's correctly pushed but if I use the timer for adding a little delay the application crash with a EXC_BAD_ACCESS. I'm pretty sure the answer contains "memory management" but I can't get the point... @interface RootViewController : UIViewController { NSTimer *timer; } -(void)changeView:(NSTimer*)theTimer; @property(nonatomic,retain) NSTimer *timer; ... @implementation RootViewController @synthesize timer; - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [[self navigationController] setNavigationBarHidden:YES]; timer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(changeView:) userInfo:nil repeats:NO]; } -(void)changeView:(NSTimer*)theTimer { NSLog(@"timer fired"); //Crash here, but only if called using a timer [[self navigationController] pushViewController:list animated:YES]; }

  • How to exercise and feel well when programming?

    - by Filip Ekberg
    While I'm sitting here in my expensive chair which was told to me were gonna help me with my neck and shoulder pains; it didn't. So don't go spend $2,000 on a chair because it's not gonna help. I am trying everything to keep my body in shape, exercising to keep my pizza-body slim and just to feel well in general. What I'd like to do is take a couple of seconds, maybe when the code compiles, to reach up, do a couple of X and feel good. But, what is this X? When I sit there at work, what will everyone think when I stand up and start to hula hula because I want to exercise my basin? I know a lot of programmers out there do have pain so let's come up with a little list together to help us all keep our joints feeling good. Programming gives me joint pain, how do i avoid it without quitting programming?

  • Common MVC 2 Pitfalls

    - by mcass20
    I surprised this hasn't been asked before...or maybe I just don't see it. Anyway, I'm finally straying from the comfort of ASP.NET Web Forms and exploring the world of MVC2. I've done the nerdinner walk-through and it was fairly straightforward. Now I am getting a little more adventurous and building an MVC2 app on my own and would like to know if there are some common pitfalls that others can attest to. Please consider my background as an ASP.NET Web Forms developer. Thanks!

  • Unit test with Authlogic on Rails 3

    - by Puru puru rin..
    Hello, I would like to write some unit test with a logged user using Authlogic. To start right, I used some code hosted in http://github.com/binarylogic/authlogic_example. But I get an error after rake test, because of "test_helper.rb" and the following class: class ActionController::TestCase setup :activate_authlogic end Here is my error: NameError: undefined local variable or method `activate_authlogic' for I think this Authlogic example is mapped over Rails 2; maybe it's a little bit different on Rails 3. Is there an other example where I can take example about unit test? Many thanks.

  • A device specific alpha bitmap fails after switching resolutions in remote desktop

    - by Bob
    All my alpha bitmaps, created using CreateCompatibleBitmap(..), start to receive an error code 87 after someone signs in with Remote Desktop. I am assuming that this is because the resolution changed and I am using a device specific bitmap. I am wondering what the best route is to fix this issue without migrating to a device independent bitmap? Some options are: 1) Detect remote desktop change and flag all bitmaps to be reloaded (I have done this but it does not work as well as I would like). 2) Wait for error code 87 to happen on an alphablend image that previously worked, and then reload it (was going to try this next, im sure it will work, but a little hacky) 3) Detect random event such as WM_DISPLAYCHANGE or _ that tells me when I should do this (ie: a device change event I'm guessing, or maybe something more specific?) 4) _? Thanks for any help in advance

  • WebsiteSpark & Visual Studio 2010

    - by Amadiere
    Having a look around at WebsiteSpark from Microsoft - the deal is good (especially if you were looking to go down this path already). But I'm one of those people that likes to 'wait for the next version' if I'm in no rush to sign up. One question that's been bugging me is whether or not the program includes upgrades to Visual Studio and/or they will change the starting pack at some point? Currently, If you sign up now, you get 3 copies of Visual Studio 2008. If you're umming and ahhing about the scheme, is it worth waiting and hoping that they adapt their program so that it comes with VS2010? Or maybe that they'll offer free updates to those already in the scheme? (This question may be a little subjective I guess and it probably applies to the BizSpark side of things as well. Have there been any hints set in other Microsoft programs that might indicate the outcome? ).

  • My first .net web app - should I go straight to MVC framework (c.f. ASP.net)

    - by Greg
    Hi, I'm done some WinForms work in C# but now moving to have to develop a web application front end in .NET (C#). I have experience developing web apps in Ruby on Rails (& a little with Java with JSP pages & struts mvc). Should I jump straight to MVC framework? (as opposed to going ASP.net) That is from the point of view of future direction for Microsoft & as well ease in ramping up from myself. Or if you like, given my experience to date, what would the pros/cons for me re MVC versus ASP.net? thanks

  • Collision detection, alternatives to "push out"

    - by LaZe
    I'm moving a character (ellipsoid) around in my physics engine. The movement must be constrained by the static geometry, but should slide on the edges, so it won't be stuck. My current approach is to move it a little and then push it back out of the geometry. It seems to work, but I think it's mostly because of luck. I fear there must be some corner cases where this method will go haywire. For example a sharp corner where two walls keeps pushing the character into each other. How would a "state of the art" game engine solve this?

  • What to do when GMap Satellite imagery is unavailable

    - by robstenson
    Hello-- is it possible to programmatically detect with the google maps api (javascript, v2) when satellite imagery is unavailable at a certain zoom level? I am creating some maps automatically and setting them to a certain zoom level, but in a few cases there is no satellite imagery available at that level, in which case I'd like to automatically back up a zoom level. Does the api expose some way of determining this lack of imagery? So far the only thing I can think of is trying to find out, with javascript, whether or not the image requests that the api makes are failing, and then reacting based on those failed image requests, but I can't really get it to work... and it seems a little inelegant. Thanks for your help!

  • Convert string to JSON using Python

    - by Luiz Fernando
    Hi, I'm a little bit confused with JSON in Python. To me, it seems like a dictionary, and for that reason I'm trying to do that: json = """{ "glossary": { "title": "example glossary", "GlossDiv": { "title": "S", "GlossList": { "GlossEntry": { "ID": "SGML", "SortAs": "SGML", "GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML", "Abbrev": "ISO 8879:1986", "GlossDef": { "para": "A meta-markup language, used to create markup languages such as DocBook.", "GlossSeeAlso": ["GML", "XML"] }, "GlossSee": "markup" } } } } } """ But when I do print dict(json), it gives an error. How can I transform this string into a structure and then call json["title"] to obtain "example glossary"? Thanks.

  • C# MySQL Lost Connection

    - by Adam
    Hi. I have C# application and I'm using MySQL database. Everything seems to be fine except one thing. Our computer network is little bit unstable. When I'm trying to execute query and the computer simultaneously loses connection to the mysql server (I'm simulating this situation by unplugging the network cable from computer which is mysql server), the program is trying to do something for long time (tens seconds). I would like to specify something like timeout which ends the query by exception or something similar. I tried to add timeout parameters to connection string but with no effect (I've used ConnectionTimeout and DefaultCommandTimeout). Is there any other way to identify lost connection after few seconds? Thank you Adam P.S. Sorry for my english, I'm not native speaker.

  • [VB.Net] System.IO will copy files, but fails to update destinations file attributes

    - by CFP
    Hello, I have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file. If IO.File.Exists(Destination) Then IO.File.SetAttributes(Destination, IO.FileAttributes.Normal) IO.File.Copy(Source, Destination, True) IO.File.SetAttributes(Destination, IO.FileAttributes.Normal) IO.File.SetLastWriteTimeUtc(Destination, IO.File.GetLastWriteTimeUtc(Destination).AddHours(1)) IO.File.SetAttributes(Destination, IO.File.GetAttributes(Source)) I however I'm encountering a quite strange problem. On some configurations, IO.File.SetLastWriteTimeUtc triggers an UnauthorizedAccess error, although the IO.File.Copy instruction worked very well. I'm totally puzzled: I've checked, and file attributes are set to 128 (ie. Normal) successfully. The problem seems to be with the very SetLastWriteTimeUtc. But what is it? Any ideas? Thanks a lot!

  • php question regarding arrays

    - by Martin
    Hi there, I'm a (complete) php noob and need a little help with something. I'm working on a project whereby a user can select up to 6 categories via a form (I'm using ExpressionEngine). The output is like this: "Cat1","Cat2","Cat3" ...and so on. The user can select up to 6 categories on that form. What I need: even if my result is 3 categories I need to have 6 'cells' - for want of a better word - even if they're empty: "Cat1","Cat2","Cat3","","","" I've tried this: <?php $str = '(output goes here)'; print_r(explode(',', $str, 6)); ?> ...but the output give me: Array ( [0] => Cat1 [1] => Cat2 [2] => Cat3 [3] => [4] => [5] => ) How do I get from that to this: "Cat1","Cat2","Cat3","","","" Does this make sense? Thanks Martin

  • Confusion on using django socialauth

    - by Fedor
    http://github.com/uswaretech/Django-Socialauth/tree/master/socialauth/ I'm a bit confused on how I should use this. Of course, I read the notes at the bottom but I'm a Django novice so I'll need a little hand holding. The structure of this looks like a project structure since it contains a urls.py but I'm also aware that applications can also have that. It also has a manage.py which leads me to believe it's a project ( plus the subdirectories ). So should I just be integrating portions of this into my existing project? This isn't an application, right? The README also mentions grabbing API Keys. So if I want a standard interface where you click on a google/yahoo logo and it forwards itself via Javascript to the authentication page where you login if you already aren't logged in, kicks you back to your own page, would I need API keys? Any other special tips are appreciated.

  • How do I customize the WPF StatusBar layout?

    - by Kent Boogaart
    Adding more than one child to a WPF StatusBar results in poor layout with little option to customize. For example, this code: <StatusBar> <StatusBarItem> <TextBlock>Ready</TextBlock> </StatusBarItem> <StatusBarItem> <TextBlock>Set</TextBlock> </StatusBarItem> </StatusBar> Results in: This is not the ideal layout, since the "Set" is squeezed right up against the "Ready". How do I gain full control over the layout of the WPF StatusBar control?

  • Java WebApp: Loading resource from .jar located in WEB-INF

    - by shaman.sir
    There are a lot of similar questions, but, probably, mine is a little bit different: What is the right way to load resource from inside of .jar file located in WEB-INF/lib folder (if I know the jar file name and the name of the class it resource belongs to), while Web Application is running? Should I use getServletContext().getResourceAsStream(?) for this purpose or the <name-of-known-class>.getResourseAsStream(?), and what path do I need to specify there? So, the structure is: /WEB-INF /classes /some/package/name ?.class #some Java code or Servlet that tries to read 'required-file.xml' /lib /<jar-with-known-name>.jar /another/package/with/known/name SomeKnownClass.class required-file.xml

  • PHP Simple modification/correction

    - by Adrian M.
    Hello, I got this code from someone, it's almost perfect to create a dynamic breadcrumb, but there just a little glitch because it echoes two dividers before the breadcrumb: $crumbs = explode("/",$_SERVER["REQUEST_URI"]); foreach($crumbs as $crumb){ echo ucfirst(str_replace(array(".php","_"),array(""," "),'>' . $crumb)); } it echoes: "contentcommonfile" what I want it to look like is "contentcommon1" and also I will deeply appreciate if someone can tell me how can I add links for all the items in the array except the last one (file)? Thank you so much everybody, this website really helped me a lot to learn php by examples!

  • OpenCV SVD Matrix format.

    - by Rick
    I currently have a set of 2D Cartesian coordinates e.g. {(1,3), (2,2), (3,4)} Which will be put into a 2D array, to perform SVD properly would the matrix be put together such that the coordinates form the columns or the rows e.g. 1 3 2 2 3 4 or 1 2 3 3 2 4 I have been doing a little trial and error comparing to examples of SVD I have found online, the resulting matrix usually seems to be negated, with some of the values shuffled around. To clarify further if I had a matrix E which was MxN as shown here http://upload.wikimedia.org/wikipedia/commons/b/bb/Matrix.svg To define the matrix as a 2D array would it be Array[M][N] or Array[N][M] I am assuming this actually matters due to matrix arithmetic not being commutative? Can anyone actually verify this?

  • std::map operator[] and automatically created new objects

    - by thomas-gies
    I'm a little bit scared about something like this: std::map<DWORD, DWORD> tmap; tmap[0]+=1; tmap[0]+=1; tmap[0]+=1; Since DWORD's are not automatically initialized, I'm always afraid of tmap[0] being a random number that is incremented. How does the map know hot to initialize a DWORD if the runtime does not know how to do it? Is it guaranteed, that the result is always tmap[0] == 3?

  • Java printf using variable field size?

    - by paxdiablo
    I'm just trying to convert some C code over to Java and I'm having a little trouble with String.printf. In C, to get a specific width based on a variable, I can use: printf("Current index = %*d\n", sz, index); and it will format the integer to be a specific size based on sz. Trying: System.out.println(String.format("Current index = %*d\n", sz, index)); results in an error since it doesn't like the *. I currently have the following kludge: System.out.println(String.format("Current index = %" + sz + "d\n", index)); but I'm hoping there's a slightly better way, yes?

  • Hibernate: How do I link a subclass to its superclass?

    - by Markus
    Hey there! I'm having a little problem setting up my webshop project. Thing is, I have a User() superclass and two subclasses, PrivateUser and BusinessUser. Now, I'm not quite sure how to get my head around storing this relationship via hibernate. For the purpose of this question, the User() class contains only one field: String address; the PrivateUser contains: String firstName; and the BusinessUser contains: String CompanyName; Each field has its getter and setter. As is right now, I would only store and be able to get firstName and companyName. When I fetch a user from my DB using Hibernate I would get a PrivateUser/BusinessUser with a null address. Bottom line is, could someone point me towards a useful tutorial or better yet show a similar example code? Thanks!

  • Bit manipulation, permutate bits

    - by triktae
    Hi. I am trying to make a loop that loops through all different integers where exactly 10 of the last 40 bits are set high, the rest set low. The reason is that I have a map with 40 different values, and I want to sum all different ways ten of these values can be multiplied. (This is just out of curiosity, so it's really the "bitmanip"-loop that is of interest, not the sum as such.) If I were to do this with e.g. 2 out of 4 bits, it would be easy to set all manually, 0011 = 7, 0101 = 5, 1001 = 9, 0110 = 6, 1010 = 10, 1100 = 12, but with 10 out of 40 I can't seem to find a method to generate these effectively. I tried, starting with 1023 ( = 1111111111 in binary), finding a good way to manipulate this, but with no success. I've been trying to do this in C++, but it's really the general method(if any) that is of interest. I did some googling, but with little success, if anyone has a good link, that would of course be appreciated too. :)

  • Vehicle 2 Vehicle Communication Questions

    - by pinnacler
    I have a rare opportunity to meet the man in charge of implementing vehicle 2 vehicle communication for the US Department of Transportation with 2 others in a few hours. Do YOU have any questions for him? I know this is a little outside the normal, but this is a 'reverse' thread and I felt he has some great knowledge on the subject that I want to share with this community. I'll post his answers later today to his questions. Ask about V2V implementation, privacy issues, use cases, or if you've thought of a great way to use V2V and want me to share it with him, he can at least think about it. He is in charge of panel that creates the standard. Or anything else...

  • Website downloader library

    - by Midhat
    I need to put a little project together for myself, and I need some functionality to download a page for offline viewing. Is there a library that will download a given page and its embedded images, and edit the img tags to reflect the local locations of the images. I know there are a lot of website downloaders out there, but I cant find something that i can use directly in my code. I have some basic scripts done in python, so Python is very welcome. but pretty much any language will do.
