  • how can I store the current status of the game in cocos2d ?

    - by srikanth rongali
    I am writing a shooting game in cocos2d. And each enemy enters the screen after the current one is dead. I have stores the enemies and their properties in plist. I need to save the current state of the game. If any phone call comes the game should be started from the current state. So, I usedNsUserDefaults in this way, - (void) applicationDidFinishLaunching:(UIApplication*)application { ... NSUserDefaults *myDefaultOptions = [[myDefaultOptions stringForKey:@"enemyNumber"]intValue] ; //tempCount4 is the current Enemy number. It was declared in another class. I am using extern and using the value here. tempCount4 = [[myDefaultOptions stringForKey:@"enemyNumber"]intValue] ; } - (void)applicationWillTerminate:(UIApplication *)application { [[CCDirector sharedDirector] end]; [myDefaultOptions setObject:tempCount4 forKey:@"enemyNumber"]; } The control is not entering in to the (void)applicationWillTerminate:(UIApplication *)application when I pressed the Home button. And when I touched the game icon on the screen the game is running from first screen and in log (terminal )it is not showing any values. And what should I store to resume my game from stored state. Can you explain where I was wrong ? Thank You.

  • Multiple Foreign keys to a single table and single key pointing to more than one table

    - by user1216775
    I need some suggestions from the database design experts here. I have around six foreign keys into a single table (defect) which all point to primary key in user table. It is like: defect (.....,assigned_to,created_by,updated_by,closed_by...) If I want to get information about the defect I can make six joins. Do we have any better way to do it? Another one is I have a states table which can store one of the user-defined set of values. I have defect table and task table and I want both of these tables to share the common state table (New, In Progress etc.). So I created: task (.....,state_id,type_id,.....) defect(.....,state_id,type_id,...) state(state_id,state_name,...) importance(imp_id,imp_name,...) There are many such common attributes along with state like importance(normal, urgent etc), priority etc. And for all of them I want to use same table. I am keeping one flag in each of the tables to differentiate task and defect. What is the best solution in such a case? If somebody is using this application in health domain, they would like to assign different types, states, importances for their defect or tasks. Moreover when a user selects any project I want to display all the types,states etc under configuration parameters section.

  • Deprecated functions not spotted if using "System::Threading::ThreadState" (and others!) C++ VS2005/

    - by Fishboy
    Hi, I'm facing an issue with c++ on vs2005 and also vs2008... here's how you can reproduce the issue.... create a new (c++) project called 'test' (file|new|project) select "Windows Forms Application" and add the 'stdio.h' include and the code fragment below into the test.cpp source file..... -------------------start of snippet-------------------- #include <stdio.h> ... int main(array<System::String ^> ^args) { int i; System::Threading::ThreadState state; char str[20]; sprintf (str, "%s", "test string"); ... -------------------end of snippet-------------------- If you compile the code as above (you'll have to 'buildall' first), you'll get two warnings about 'i' and 'state' being unreferenced (nothing about sprintf being deprecated). If you comment out "System::Threading :Thread state;", you'll get one warning about 'i' being unreferenced and another warning (C4996) for the 'deprecated' sprintf statement.... This issue also occurs for "System::Windows::Forms::MessageBoxIcon", "System::Base64FormattingOptions" (and perhap all 'enum class' types!) Anyone know of the cause and workaround to the issue demonstrated here ( i have other files that demonstate this issue..). (I had started a thread on msdn, but then found this site! see link below) Visual Studio 2005 has stopped warning about deprecated functions

  • Python "callable" attribute (pseudo-property)

    - by mgilson
    In python, I can alter the state of an instance by directly assigning to attributes, or by making method calls which alter the state of the attributes: foo.thing = 'baz' or: foo.thing('baz') Is there a nice way to create a class which would accept both of the above forms which scales to large numbers of attributes that behave this way? (Shortly, I'll show an example of an implementation that I don't particularly like.) If you're thinking that this is a stupid API, let me know, but perhaps a more concrete example is in order. Say I have a Document class. Document could have an attribute title. However, title may want to have some state as well (font,fontsize,justification,...), but the average user might be happy enough just setting the title to a string and being done with it ... One way to accomplish this would be to: class Title(object): def __init__(self,text,font='times',size=12): self.text = text self.font = font self.size = size def __call__(self,*text,**kwargs): if(text): self.text = text[0] for k,v in kwargs.items(): setattr(self,k,v) def __str__(self): return '<title font={font}, size={size}>{text}</title>'.format(text=self.text,size=self.size,font=self.font) class Document(object): _special_attr = set(['title']) def __setattr__(self,k,v): if k in self._special_attr and hasattr(self,k): getattr(self,k)(v) else: object.__setattr__(self,k,v) def __init__(self,text="",title=""): self.title = Title(title) self.text = text def __str__(self): return str(self.title)+'<body>'+self.text+'</body>' Now I can use this as follows: doc = Document() doc.title = "Hello World" print (str(doc)) doc.title("Goodbye World",font="Helvetica") print (str(doc)) This implementation seems a little messy though (with __special_attr). Maybe that's because this is a messed up API. I'm not sure. Is there a better way to do this? Or did I leave the beaten path a little too far on this one? I realize I could use @property for this as well, but that wouldn't scale well at all if I had more than just one attribute which is to behave this way -- I'd need to write a getter and setter for each, yuck.

  • What is preferred method for searching table data using stored procedure?

    - by Mourya
    I have a customer table with Cust_Id, Name, City and search is based upon any or all of the above three. Which one Should I go for ? Dynamic SQL: declare @str varchar(1000) set @str = 'Select [Sno],[Cust_Id],[Name],[City],[Country],[State] from Customer where 1 = 1' if (@Cust_Id != '') set @str = @str + ' and Cust_Id = ''' + @Cust_Id + '''' if (@Name != '') set @str = @str + ' and Name like ''' + @Name + '%''' if (@City != '') set @str = @str + ' and City like ''' + @City + '%''' exec (@str) Simple query: select [Sno],[Cust_Id],[Name],[City],[Country],[State] from Customer where (@Cust_Id = '' or Cust_Id = @Cust_Id) and (@Name = '' or Name like @Name + '%') and (@City = '' or City like @City + '%') Which one should I prefer (1 or 2) and what are advantages? After going through everyone's suggestion , here is what i finally got. DECLARE @str NVARCHAR(1000) DECLARE @ParametersDefinition NVARCHAR(500) SET @ParametersDefinition = N'@InnerCust_Id varchar(10), @InnerName varchar(30),@InnerCity varchar(30)' SET @str = 'Select [Sno],[Cust_Id],[Name],[City],[Country],[State] from Customer where 1 = 1' IF(@Cust_Id != '') SET @str = @str + ' and Cust_Id = @InnerCust_Id' IF(@Name != '') SET @str = @str + ' and Name like @InnerName' IF(@City != '') SET @str = @str + ' and City like @InnerCity' -- ADD the % symbol for search based upon the LIKE keyword SELECT @Name = @Name + '%', @City = @City+ '%' EXEC sp_executesql @str, @ParametersDefinition, @InnerCust_Id = @Cust_Id, @InnerName = @Name, @InnerCity = @City; References : http://blogs.lessthandot.com/index.php/DataMgmt/DataDesign/changing-exec-to-sp_executesql-doesn-t-p http://msdn.microsoft.com/en-us/library/ms175170.aspx

  • How to make link become inactive?

    - by Konstantin Vasilcov
    The idea was simple: change li background color on hover to one color ul#menu li a:hover {...} change it on mouse press to the other color ul#menu li a:active {...} return the color to the original (normal) if the link is neither hover nor pressed The problem appeared to be that, if user rejected his intention and lets the mouse up away from the link, the back color stays as if it was pressed. Then I tried to research and came up with this: ul#menu li a:hover:active {...} It became better, and the link is not marked with special back color in a normal state after user presses the link and rejects. But the "on-hover" back color became equal to the active one. So it looks like the link gets "active" state and stays in it even after user releases mouse button. Hate to write this, but I am very new to html and css. So I may be missing something very basic here. Could you, please, suggest any way, how to achieve my goal? EDIT I've read this source CSS Styling links (thought there could be some other state to use instead of active), but found nothing suitable there...

  • Is there such a thing as a MemberExpression that handles a many-to-many relationship?

    - by Jaxidian
    We're trying to make it easy to write strongly-typed code in all areas of our system, so rather than setting var sortColumn = "FirstName" we'd like to say sortOption = (p => p.FirstName). This works great if the sortOption is of type Expression<Func<Person, object>> (we actually use generics in our code but that doesn't matter). However, we run into problems for many-to-many relationships because this notation breaks down. Consider this simple code: internal class Business { public IQueryable<Address> Addresses { get; set; } public string Name { get; set; } } internal class Address { public State MyState { get; set; } } internal class State { public string Abbreviation { get; set; } public int StateID { get; set; } } Is it possible to have this sort of MemberExpression to identify the StateID column off of a business? Again, the purpose of using this is not to return a StateID object, it's to just identify that property off of that entity (for sorting, filtering, and other purposes). It SEEMS to me that there should be some way to do this, even if it's not quite as pretty as foo = business.Addresses.SomeExtension(a => a.State.StateID);. Is this really possible? If more background is needed, take a look at this old question of mine. We've since updated the code significantly, but this should give you the general detailed idea of the context behind this question.

  • Patterns to deal with with functions that can have different kinds of results.

    - by KaptajnKold
    Suppose you have an method on an object that given the some input alters the objects state if the input validates according to some complex logic. Now suppose that when the input doesn't validate, it can be due to several different things, each of which we would like to be able to deal with in different ways. I'm sure many of you are thinking: That's what exceptions are for! I've thought of this also. But my reservation against using exceptions is that in some cases there is nothing exceptional about the input not validating and I really would like to avoid using exceptions to control what is really just in the expected flow of the program. If there were only one interpretation possible, I could simply choose to return a boolean value indicating whether or not the operation resulted in a state change or not and the respond appropriately when it did not. There is of course also the option to return a status code which the client can then choose to interpret or not. I don't like this much either because there is nothing semantic about status codes. The solution I have so far is to always check for each possible situation which I am able to handle before I call the method which then returns a boolean to inform the client if the object changed state. This leaves me the flexibility to handle as few or as many as the possible situations as I wish depending on the context I am in. It also has the benefit of making the method I am calling simpler to write. The drawback is that there is quite a lot of duplication in the client code wherever I call the method. Which of these solutions do you prefer and why? What other patterns do people use for providing meaningful feedback from functions? I know that some languages support multiple return values, and I if I had that option I would surely prefer it.

  • Drag and Drop in MVVM with ScatterView

    - by Rich McGuire
    I'm trying to implement drag and drop functionality in a Surface Application that is built using the MVVM pattern. I'm struggling to come up with a means to implement this while adhering to the MVVM pattern. Though I'm trying to do this within a Surface Application I think the solution is general enough to apply to WPF as well. I'm trying to produce the following functionality: User contacts a FrameworkElement within a ScatterViewItem to begin a drag operation (a specific part of the ScatterViewItem initiates the drag/drop functionality) When the drag operation begins a copy of that ScatterViewItem is created and imposed upon the original ScatterViewItem, the copy is what the user will drag and ultimately drop The user can drop the item onto another ScatterViewItem (placed in a separate ScatterView) The overall interaction is quite similar to the ShoppingCart application provided in the Surface SDK, except that the source objects are contained within a ScatterView rather than a ListBox. I'm unsure how to proceeded in order to enable the proper communication between my ViewModels in order to provide this functionality. The main issue I've encountered is replicating the ScatterViewItem when the user contacts the FrameworkElement.

  • RowFilter.regexFilter multiple columns

    - by twodayslate
    I am currently using the following to filter my JTable RowFilter.regexFilter( Pattern.compile(textField.getText(), Pattern.CASE_INSENSITIVE).toString(), columns ); How do I format my textField or filter so if I want to filter multiple columns I can do that. Right now I can filter multiple columns but my filter can only be of one of the columns An example might help my explanation better: Name Grade GPA Zac A 4.0 Zac F 1.0 Mike A 4.0 Dan C 2.0 The text field would contain Zac A or something similar and it would show the first Zac row if columns was int[]{0, 1}. Right now if I do the above I get nothing. The filter Zac works but I get both Zac's. A also works but I would then get Zac A 4.0 and Mike A 3.0. I hope I have explained my problem well. Please let me know if you do not understand.

  • Looking for search syntax documentation for SharePoint UserProfileManager.Search Method

    - by gregenslow
    Greetings - I have a SharePoint 2010 server running with the User Profile service setup to synchronize to Active Directory. I'd like to use the UserProfileManager.Search() method to return user profiles based on specific criteria. MSDN documentation for this method is here. It states that the method will return user profiles that match the specified search pattern. This is exactly what I want. However, there is no documentation on what a valid search pattern is. I've made a few guesses like "Department = 'HR'" but haven't had any luck. I can't find any other documentation or sample code. Can anyone provide samples of valid "search patterns?" Another way to return user profiles is to do a query using the FullTextSqlQuery object. We don't yet have Search setup on this server so this isn't currently an option. Thanks, Greg

  • Escaping an equals sign in DOS batch string replacement command

    - by Alastair
    I need to replace some text in a JNLP file using a DOS batch file to tune it for the local machine. The problem is that the search pattern contains an equals sign which is messing up the string replacement in the batch file. I want to replace the line, <j2se version="1.5" initial-heap-size="100M" max-heap-size="100M"/> with specific settings for the initial and max heap sizes. For example at the moment I have, for /f "tokens=* delims=" %%a in (%filePath%agility.jnlp) do ( set str=%%a set str=!str:initial-heap-size="100M"=initial-heap-size="%min%M"! echo !str!>>%filePath%new.jnlp) but the = in the search pattern is being read as part of the replacement command. How do I escape the equals sign so it is processed as text?

  • How to stop Spring MVC blocking all other Servlets?

    - by Dag
    Hi, I'm using Spring 2.5 MVC and wan't to add another third-party Servlet. The Problem is, that Spring MVC catches all request, so the Servlet isn't getting any request. Here a web.xml Snippet: SpringMVC org.springframework.web.servlet.DispatcherServlet 2 <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <servlet> This is the servlet needed for cache.type servlet, returns the packed resources PackServlet PackServlet net.sf.packtag.servlet.PackServlet PackServlet *.pack The /* mapping is really needed for the application, an pack:tag (the third-party Servlet) really need the mapping based on the file extension. Any possiblities to tell Spring not to process the request? Thanks and regards.

  • NHibernate Session Management Advice

    - by Hugusta
    I need some advice on NHibernate Session Management for a C# WinForms application. I am currently porting an application to use NHibernate. I am also employing a UnitOfWork pattern as described in the link below; http://nhforge.org/wikis/patternsandpractices/nhibernate-and-the-unit-of-work-pattern.aspx My question relates to Sessions. Can you only have one session running per thread at all times? I have a scenario in which a Session (UnitOfWork) may be open for a form shown by the application but the user opens another form (i.e. Tools - Options) which I would like to have its own UnitOfWork. Clearly in this instance it would make more sense to open another Session for the "Tools - Options" form and not use the currently open session for the underlying form. Can we have a Dictionary of Sessions on the one thread? Any advice on session management is appreciated.

  • Switching from LinqToXYZ to LinqToObjects

    - by spender
    In answering this question, it got me thinking... I often use this pattern: collectionofsomestuff //here it's LinqToEntities .Select(something=>new{something.Name,something.SomeGuid}) .ToArray() //From here on it's LinqToObjects .Select(s=>new SelectListItem() { Text = s.Name, Value = s.SomeGuid.ToString(), Selected = false }) Perhaps I'd split it over a couple of lines, but essentially, at the ToArray point, I'm effectively enumerating my query and storing the resulting sequence so that I can further process it with all the goodness of a full CLR to hand. As I have no interest in any kind of manipulation of the intermediate list, I use ToArray over ToList as there's less overhead. I do this all the time, but I wonder if there is a better pattern for this kind of problem?

    Hi, have I have a quesition regarding MVVM pattern in the uses case of diagramming. What I have so far is a list of Items which are my Shapes. ObservableCollection<ItemsViewModels> Items; and a Collection of Connection of Items ObservableCollection<ConnectionViewModel> Each ItemViewModel has an ID and a ConnectionViewModel has two ID to connect the Items. My ItemsViewModel Collection is bound to a itemscontrol which is layout on a Canvas. With the ElementMouseDragBehavior I am able to drag my Items around. Now comes my big question =) How can I visualize my connections that I will be able to move the items around and the items stay connected with a line either straign or bezier. I don't know how to abstract that with the mvvm pattern. Thanks for any help...

  • Is MVVM pointless?

    - by joebeazelman
    Is orthodox MVVM implementation pointless? I am creating a new application and I considered Windows Forms and WPF. I chose WPF because it's future-proof and offer lots of flexibility. There is less code and easier to make significant changes to your UI using XAML. Since the choice for WPF is obvious, I figured that I may as well go all the way by using MVVM as my application architecture since it offers blendability, separation concerns and unit testability. Theoretically, it seems beautiful like the holy grail of UI programming. This brief adventure; however, has turned into a real headache. As expected in practice, I’m finding that I’ve traded one problem for another. I tend to be an obsessive programmer in that I want to do things the right way so that I can get the right results and possibly become a better programmer. The MVVM pattern just flunked my test on productivity and has just turned into a big yucky hack! The clear case in point is adding support for a Modal dialog box. The correct way is to put up a dialog box and tie it to a view model. Getting this to work is difficult. In order to benefit from the MVVM pattern, you have to distribute code in several places throughout the layers of your application. You also have to use esoteric programming constructs like templates and lamba expressions. Stuff that makes you stare at the screen scratching your head. This makes maintenance and debugging a nightmare waiting to happen as I recently discovered. I had an about box working fine until I got an exception the second time I invoked it, saying that it couldn’t show the dialog box again once it is closed. I had to add an event handler for the close functionality to the dialog window, another one in the IDialogView implementation of it and finally another in the IDialogViewModel. I thought MVVM would save us from such extravagant hackery! There are several folks out there with competing solutions to this problem and they are all hacks and don’t provide a clean, easily reusable, elegant solution. Most of the MVVM toolkits gloss over dialogs and when they do address them, they are just alert boxes that don’t require custom interfaces or view models. I’m planning on giving up on the MVVM view pattern, at least its orthodox implementation of it. What do you think? Has it been worth the trouble for you if you had any? Am I just a incompetent programmer or does MVVM not what it's hyped up to be?

  • Git ignore sub folders

    - by Marcel
    I have a lot of projects in my .Net solution. I would like to exclude all "bin/Debug" and "bin/Release" folders (and their contents), but still include the "bin" folder itself and any dll's contained therein. .gitignore with "bin/" ignores "Debug" and "Release" folders, but also any dll's contained in the "bin" folder. "bin/Debug" or "bin/Release" in the .gitignore file does not exclude the directories, unless I fully qualify the ignore pattern as "Solution/Project/bin/Debug" - which I don't want to do as I will need to include this full pattern for each project in my solution, as well as add it for any new projects added. Any suggestions?

  • Spring-security not processing pre/post annotations

  • How to avoid using duplicate savepoint names in nested transactions in nested stored procs?

    - by Gary McGill
    I have a pattern that I almost always follow, where if I need to wrap up an operation in a transaction, I do this: BEGIN TRANSACTION SAVE TRANSACTION TX -- Stuff IF @error <> 0 ROLLBACK TRANSACTION TX COMMIT TRANSACTION That's served me well enough in the past, but after years of using this pattern (and copy-pasting the above code), I've suddenly discovered a flaw which comes as a complete shock. Quite often, I'll have a stored procedure calling other stored procedures, all of which use this same pattern. What I've discovered (to my cost) is that because I'm using the same savepoint name everywhere, I can get into a situation where my outer transaction is partially committed - precisely the opposite of the atomicity that I'm trying to achieve. I've put together an example that exhibits the problem. This is a single batch (no nested stored procs), and so it looks a little odd in that you probably wouldn't use the same savepoint name twice in the same batch, but my real-world scenario would be too confusing to post. CREATE TABLE Test (test INTEGER NOT NULL) BEGIN TRAN SAVE TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (1) COMMIT TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (2) COMMIT TRAN TX DELETE FROM Test ROLLBACK TRAN TX COMMIT TRAN TX SELECT * FROM Test DROP TABLE Test When I execute this, it lists one record, with value "1". In other words, even though I rolled back my outer transaction, a record was added to the table. What's happening is that the ROLLBACK TRANSACTION TX at the outer level is rolling back as far as the last SAVE TRANSACTION TX at the inner level. Now that I write this all out, I can see the logic behind it: the server is looking back through the log file, treating it as a linear stream of transactions; it doesn't understand the nesting/hierarchy implied by either the nesting of the transactions (or, in my real-world scenario, by the calls to other stored procedures). So, clearly, I need to start using unique savepoint names instead of blindly using "TX" everywhere. But - and this is where I finally get to the point - is there a way to do this in a copy-pastable way so that I can still use the same code everywhere? Can I auto-generate the savepoint name on the fly somehow? Is there a convention or best-practice for doing this sort of thing? It's not exactly hard to come up with a unique name every time you start a transaction (could base it off the SP name, or somesuch), but I do worry that eventually there would be a conflict - and you wouldn't know about it because rather than causing an error it just silently destroys your data... :-(

  • I'm going to write 'Unit of Work', please help me find out all gimmicks

    - by o..o
    Hi everybody, I'm going to write my own DAL in C#. I decided to use 'Unit of Work' pattern (next mentioned as uow) with request as a scope and Identity map stored in HttpContext.Items. I have right now question about implementing of CRUD methods. How/where are they implemented? Are they implemented in every single business class (as in active records pattern) or are implemented somehow in uow class (if so, how)? I also suppose that I need to use as the scope not just the request, but also the db connection. But how? Should I open the connection a the start of the request and close it on uow disposing? Every advice is strongly appreciated, especially Your "real world" experiences. Thank you all :)

  • How to get SVN to ignore Mac "._" files?

    - by Dave Child
    My development server is accessed by several OSX users, and their OS tends to leave lots of unnecessary files around the place, all starting with dot underscore ("._"). I know OSX can be told not to create these on network drives, but they still sneak in. I'd like SVN to ignore anything starting with "._", but I can't seem to get it to work, even though it looks like it should be simple. I've added "._*" to the SVN global ignore pattern, but SVN is still trying to add and commit these files. Can anyone tell me what I'm doing wrong? My full SVN ignore pattern is: global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo *.rej *~ #*# .#* .*.swp .DS_Store Thumbs.db ._* *.bak *.tmp nbproject I don't know if it makes any difference, but I'm trying to set this on both Ubuntu and Ubuntu server by editing the /etc/subversion/config file.

  • Neon toolkit and Gate Web Service

    - by blueomega
    I am trying to run any of the services from gate web service, in neon 2.3. Even Annie that runs so well in gate doesn't run, or better, it stay for indefinite time processing, a thing that should take no more than a couple of seconds. I run wizard, set input directory, leave file pattern as default and set a folder and name for the output ontology, shouldn't it be enough? Shouldn't i get something, even an error? I think its the location who's giving me problems. http://safekeeper1.dcs.shef.ac.uk/neon/services/sardine http://safekeeper1.dcs.shef.ac.uk/neon/services/sprat http://safekeeper1.dcs.shef.ac.uk/neon/services/annie http://safekeeper1.dcs.shef.ac.uk/neon/services/termraider How can i confirm it? Can i run it offline? Can anyone give me a hand? Also, i've seen sprat running on gate, on "SPRAT: a tool for automatic semantic pattern-based ontology population" Can anyone teach me how, and with what versions? Thx, Celso Costa
