  • Pagination in Tab Content of Jquery UI

    - by DR.GEWA
    I am making a page with Jquery UI TABS. In one of tabs I want to make pagination for comments. I want such thing. When user clicks on the number of the page, the data of the page , which is linked will load via ajax in the tab. Here is my code <script type="text/javascript"> $(function() { $("#tabs").tabs(); }); $('#demo').tabs({ load: function(event, ui) { $('a', ui.panel).click(function() { $(ui.panel).load(this.href); return false; }); } }); </script> How can I change this , so that any link inside the content with lets say with id "pagination" <a href="/coments?page=12&user_id=12" id="pagination">12</a> ?? Thanks beforehand I tried recently like this even and no luck. This is from http://www.bannerite.com/jquerytest/index2.php Here it work <script type="text/javascript"> $(function() { $("#tabs").tabs(); var hijax = function(panel){ $('a', panel).click(function() { /**makes children 'a' on panel load via ajax, hence hijax*/ $(panel).load(this.href, null, function(){ /**recursively apply the hijax to newly loaded panels*/ hijax(panel); }); /**prevents propagation of click to document*/ return false; }); $('form', panel).css({background: 'yellow'}).ajaxForm({ target: panel, }); }; $('#demo ul').tabs({ /**initialize the tabs hijax pattern*/ load: function(tab, panel) { hijax(panel); } }); }); </script> HEre are the HTML part as Karl gived , but no succes. When clicking on Test link its going to another page........ When clicking on I wanted to post HTML here but because of users with less reputation <10 cant give HTML with links I have posted it here http://gevork.ru/2009/12/31/jquery-ui-tab-and-pagination-html/#more-58

  • Sample uniformly at random from an n-dimensional unit simplex.

    - by dreeves
    Sampling uniformly at random from an n-dimensional unit simplex is the fancy way to say that you want n random numbers such that they are all non-negative, they sum to one, and every possible vector of n non-negative numbers that sum to one are equally likely. In the n=2 case you want to sample uniformly from the segment of the line x+y=1 (ie, y=1-x) that is in the positive quadrant. In the n=3 case you're sampling from the triangle-shaped part of the plane x+y+z=1 that is in the positive octant of R3: (Image from http://en.wikipedia.org/wiki/Simplex.) Note that picking n uniform random numbers and then normalizing them so they sum to one does not work. You end up with a bias towards less extreme numbers. Similarly, picking n-1 uniform random numbers and then taking the nth to be one minus the sum of them also introduces bias. Wikipedia gives two algorithms to do this correctly: http://en.wikipedia.org/wiki/Simplex#Random_sampling (Though the second one currently claims to only be correct in practice, not in theory. I'm hoping to clean that up or clarify it when I understand this better. I initially stuck in a "WARNING: such-and-such paper claims the following is wrong" on that Wikipedia page and someone else turned it into the "works only in practice" caveat.) Finally, the question: What do you consider the best implementation of simplex sampling in Mathematica (preferably with empirical confirmation that it's correct)?

  • Facebook with RestFB

    - by Trick
    I just began to use this and I already stumbled on some from-my-side-strange errors. I am using RestFB jar. My problem is, that I can not get my session key (this is the start of everything :)). FacebookClient facebookClient = new DefaultFacebookClient(API_KEY, SECRET_KEY); try { String token = facebookClient.execute("auth.createToken", String.class, Parameter.with("null", "null")); System.out.println(token); String session = facebookClient.execute("auth.getSession", String.class, Parameter.with("auth_token", token)); System.out.println(session); } catch (FacebookException e) { e.printStackTrace(); } I get the token correctly. Parameter.with("null,"null") is there because it demands at least one, but method for creating token doesn't expect any. When trying to get the session key, I get the following error: com.restfb.FacebookResponseStatusException: Received Facebook error response (code 100): Invalid parameter at com.restfb.DefaultFacebookClient.throwFacebookResponseStatusExceptionIfNecessary(DefaultFacebookClient.java:357) at com.restfb.DefaultFacebookClient.makeRequest(DefaultFacebookClient.java:320) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:188) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:178) Documentation for getting session doesn't say any more parameters are required! Did anybody already try this JAR or do you have any other solution for Java?

  • URL detection with JavaScript

    - by josh
    Hi! I'm using the following script to force a specific page - when loaded for the first time - into a (third-party) iFrame. <script type="text/javascript"> if(window.top==window) { location.reload() } else { } </script> (For clarification: This 'embedding' is done automatically by the third-party system but only if the page is refreshed once - for styling and some other reasons I want it there from the beginning.) Right now, I'm wondering if this script could be enhanced in ways that it's able to detect the current URL of its 'parent' document to trigger a specific action? Let's say the URL of the third-party site is 'http://cgi.site.com/hp/...' and the URL of the iFrame 'http://co.siteeps.com/hp/...'. Is it possible to realize sth. like this with JS: <script type="text/javascript"> if(URL is 'http://cgi.site.com/hp/...') { location.reload() } if(URL is 'http://co.siteeps.com/hp/...') { location.do-not.reload() resp. location.do-nothing() } </script> TIA josh

  • "Admin module" taking over [Yii framework]

    - by Flavius
    Hi I have an "admin" module and I want it to serve "dynamic controllers", i.e. to provide a default behaviour for controllers which don't really exist ("virtual controllers"). I've invented a lightweight messaging mechanism for loose communication between modules. I'd like to use it such that when e.g. ?r=admin/users/index is requested, it will call the "virtual controller" "UserController" of AdminModule, which would, by default, use this messaging mechanism to notify the real module "UsersModule" it can answer to the request. I thought about simulating this behaviour in AdminModule::init(), but at that point I have no way of deciding whether the action can be processed by a real controller or not, or at least I don't know how to do it. This is because of the way Yii works: bottom-up, the controller is the one that renders the view AND the application layout (or the module's, if it exists), for example. I don't think the module even has a word to say about handling a given controller+action or not. To recap, I'm looking for a kind of CWebModule::missingController($controllerId,$actionId), just like CController::missingAction($actionId), or a workaround to simulate that. That would possibly be in CWebModule::init() or somewhere where I can find out whether the controller actually exists, in which case it's his job to handle it the $actionID and $controllerID whether the module $controllerID exists (I didn't type it wrong, in r=admin/users/index, "users" is the actual module, as specified in the application's config).

  • TeX Font Mapping

    - by reprogrammer
    I am using a package written on top of XeLaTeX. This package uses fontspec to specify fonts for different parts of your text: latin, non-latin, math mode, ... The package comes with several sample files. I was able to xelatex most of them that depend on regular ttf or otf files. However, one of them tries to set the font of digits in math mode to some font, say "NonLatin Digits". But, the font doesn't seem to be a regular font. There are two files in the same directory called "nonlatindigits.map" and "nonlatindigits.tec". TECkit uses these mapping files to generate TeX fonts. However, for some reason it fails to create the files, and xelatex issues the following error message. kpathsea: Invalid fontname `NonLatin Digits', contains ' ' ! Font \zf@basefont="NonLatin Digits" at 10.0pt not loadable: Metric (TFM) file or installed font not found. The kpathsea program complains about the whitespace, but removing the whitespace does solve the problem with loading the TFM file. Any clues what I am doing wrong?

  • Error editing a blob field in ArcGIS Engine

    - by Victor Grigoriu
    I have a GIS layer backed by a MSSQL db. The features on the layer have, say, one field of type esriFieldTypeString and one of type esriFieldTypeBlob. I can edit the string field just fine, but, when I try to edit a blob, StopEditOperation() throws a very generic exception (message: "Error HRESULT E_FAIL has been returned from a call to a COM component.", error code: -2147467259). I couldn't find anything related in the server log. Does anyone have any idea what's going on? IServerContext serverContext = GetServerContext(agsConn, serviceName); ILayer layer = GetILayer(layerName, serverContext); IWorkspace workspace = GetIWorkspace(layer); var feature = GetIFeature(objectId, workspace, layer); var workspaceEdit = (IWorkspaceEdit)workspace; workspaceEdit.StartEditing(false); workspaceEdit.StartEditOperation(); var index = feature.Fields.FindField(featureDetailName); IField field = feature.Fields.get_Field(index); byte[] byteArray = {1, 2, 3}; MemoryBlobStream blob = new MemoryBlobStream(); ((IMemoryBlobStreamVariant)blob).ImportFromVariant(byteArray); if (field.CheckValue(blob)) { feature.set_Value(index, blob); } feature.Store(); workspaceEdit.StopEditOperation(); workspaceEdit.StopEditing(true); serverContext.RemoveAll(); serverContext.ReleaseContext();

  • UIWebView not loading URL when URL is passed from UITableView

    - by Mark Hazlett
    Hey Everyone, So i'm building a webView into my application to show the contents of a URL that I am passing from a selection in a UITableView. I know the UIWebView is loading content properly because if you hard code say http://www.google.ca into the NSURL then it loads fine, however when I'm passing the URL that I parsed from an RSS feed back from the UITableView it won't load the URL properly. I tried the debugger and the URL is coming out as nil right before I try and parse it, however I can use NSLog to print the value of it out to the console. here's the code in my UIViewController that has my UIWebView #import <UIKit/UIKit.h> @interface ReadFeedWebViewController : UIViewController { NSString *urlToGet; IBOutlet UIWebView *webView; } @property(nonatomic, retain) IBOutlet UIWebView *webView; @property(nonatomic, retain) NSString *urlToGet; @end Here's the code for my implementation's viewDidLoad method... // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"Url inside Web View Controller - %@", urlToGet); NSURL *url = [NSURL URLWithString:urlToGet]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:requestObj]; } Once again, I can print the URL to NSLog fine and if I hard code the URL into the NSURL object then it will load fine in the UIWebView. Here is where I'm setting the value in my UITableViewController... - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { ReadFeedWebViewController *extendedView = [[ReadFeedWebViewController alloc] init]; int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; extendedView.urlToGet = [[stories objectAtIndex: storyIndex] objectForKey:@"link"]; //NSLog([[stories objectAtIndex: storyIndex] objectForKey:@"summary"]); NSLog([[stories objectAtIndex: storyIndex] objectForKey:@"link"]); [self.navigationController pushViewController:extendedView animated:YES]; [extendedView release]; } However, since I can print the value using NSLog in the extendedView view controller I know it's being passed properly. Cheers

  • Reattaching an object graph to an EntityContext: "cannot track multiple objects with the same key"

    - by dkr88
    Can EF really be this bad? Maybe... Let's say I have a fully loaded, disconnected object graph that looks like this: myReport = {Report} {ReportEdit {User: "JohnDoe"}} {ReportEdit {User: "JohnDoe"}} Basically a report with 2 edits that were done by the same user. And then I do this: EntityContext.Attach(myReport); InvalidOperationException: An object with the same key already exists in the ObjectStateManager. The ObjectStateManager cannot track multiple objects with the same key. Why? Because the EF is trying to attach the {User: "JohnDoe"} entity TWICE. This will work: myReport = {Report} {ReportEdit {User: "JohnDoe"}} EntityContext.Attach(myReport); No problems here because the {User: "JohnDoe"} entity only appears in the object graph once. What's more, since you can't control how the EF attaches an entity, there is no way to stop it from attaching the entire object graph. So really if you want to reattach a complex entity that contains more than one reference to the same entity... well, good luck. At least that's how it looks to me. Any comments? UPDATE: Added sample code: // Load the report Report theReport; using (var context1 = new TestEntities()) { context1.Reports.MergeOption = MergeOption.NoTracking; theReport = (from r in context1.Reports.Include("ReportEdits.User") where r.Id == reportId select r).First(); } // theReport looks like this: // {Report[Id=1]} // {ReportEdit[Id=1] {User[Id=1,Name="John Doe"]} // {ReportEdit[Id=2] {User[Id=1,Name="John Doe"]} // Try to re-attach the report object graph using (var context2 = new TestEntities()) { context2.Attach(theReport); // InvalidOperationException }

  • How to edit the XSL for RSS Viewer Webpart

    - by Nagendra
    I am using a blog site as a source for my RSS Feed. As I see the RSS feed, its showing up as the following :: Blog: Posts Test Thursday, March 04, 2010 - Body: With 25 four's and 3 sixers Sachin crosses 200 (147 balls) runs in an single ODI innings. Creates another world record. Watch the final over where he got it double hundred with MSD on the other end. This is what he had to say after getting the MOM (man of the match): I dedicate this knock to all the people of India, who have supported me throughout over the last 20 years. I was timing the ball well, and I felt that anywhere between 340 to 350 was a good target. I thought Karthik, Yusuf and Dhoni supported me well. I thought that a 200 would be possible once I crossed 175 in the 42nd over. I am enjoying my cricket at the moment. There have been a few bad decisions I have made as a batsman, but as long as the passion is there I will carry on. It feels good that I lasted the 50 overs, it was a good test of my fitness and I would like to do this once again. Well!!! Wait for more. Published: 3/4/2010 3:18 PM More... I actually wanted to remove the Body, Published parameters. I just want my XSLT to be able to show only the Description of the blog. No need to have this meta data. Can anyone help me in specifying tthe XSL changes?

  • Populating Models from other Models in Django?

    - by JT
    This is somewhat related to the question posed in this question but I'm trying to do this with an abstract base class. For the purposes of this example lets use these models: class Comic(models.Model): name = models.CharField(max_length=20) desc = models.CharField(max_length=100) volume = models.IntegerField() ... <50 other things that make up a Comic> class Meta: abstract = True class InkedComic(Comic): lines = models.IntegerField() class ColoredComic(Comic): colored = models.BooleanField(default=False) In the view lets say we get a reference to an InkedComic id since the tracer, err I mean, inker is done drawing the lines and it's time to add color. Once the view has added all the color we want to save a ColoredComic to the db. Obviously we could do inked = InkedComic.object.get(pk=ink_id) colored = ColoredComic() colored.name = inked.name etc, etc. But really it'd be nice to do: colored = ColoredComic(inked_comic=inked) colored.colored = True colored.save() I tried to do class ColoredComic(Comic): colored = models.BooleanField(default=False) def __init__(self, inked_comic = False, *args, **kwargs): super(ColoredComic, self).__init__(*args, **kwargs) if inked_comic: self.__dict__.update(inked_comic.__dict__) self.__dict__.update({'id': None}) # Remove pk field value but it turns out the ColoredComic.objects.get(pk=1) call sticks the pk into the inked_comic keyword, which is obviously not intended. (and actually results in a int does not have a dict exception) My brain is fried at this point, am I missing something obvious, or is there a better way to do this?

  • Tricky CSS Layout

    - by Meep3D
    So I am making a website with quite a problematic layout. There are four corner images TL, TR, BL and BR indicated by black blocks. The dark orange area is the main content (to a width of 960px), with the outside area denoted by the green arrow as the browser window. See diagram: The top image represents the site at its narrowest possible - it shouldn't be allowed to be narrower than this (960px) if it is larger than the defined area there should be no scrollbars. The bottom two images represent different widths of browser. The bottom left and right black blocks (images) should be at the bottom left and right of the screen at all times, unless the width falls to 960px, in which case the BL and BR images should poke into the main area slightly. If the site is shrunk to, say 200px, the BR image should not still be poking in the right corner. At this point I don't really care about it working exactly in IE6 (I can get it roughly working) but I can't even figure out how to do it fully without Javascript or extremely experimental CSS. Currently I am using absolutely positioned div's which sort of work, but don't work quite right. I think I'd be willing to accept a bit of JS if there is no other way but I'd rather not. Answer very appreciated!

  • ListView + MultipleSelect + MVVM = ?

    - by Dave
    If I were to say "the heck with it!", I could just give my ListView with SelectionMode="Multiple" a name, and be able to get all of the selected items very easily. But I'm trying to stick to MVVM as much as possible, and I want to somehow databind to an ObservableCollection that holds the value from the Name column for each selected item. How in the world do you do this? Single selection is simple, but the multi selection solution is not obvious to me with my current WPF / MVVM knowledge. I read this question on SO, and while it does give me some good insight, I don't know how to add the necessary binding to a row, because I am using a ListView with a GridView as its View, not a ListBox. Here's what my XAML basically looks like: <ListView DockPanel.Dock="Top" ItemsSource="{Binding ClientPreview}" SelectionMode="Multiple"> <ListView.View> <GridView AllowsColumnReorder="False"> <GridViewColumn Header="Name"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Name}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header="Address"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Address}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> It sounds like the right thing to do is to databind each row's IsSelected property to each object stored in the ObservableCollection I'm databinding to. I just haven't figured out how to do this.

  • Does anyone use Fortify 360 with Classic ASP? a Header Manipulation vulnerability story

    - by j_green71
    Good morning, everyone. I'm on a short-term contracting gig, trying to patch some vulnerabilities in their legacy code. The application I'm working on is a combination of Classic ASP(VBScript) and .Net 2.0 (C#). One of the tools they have purchased is Fortify 360. Let's say that this is a current classic ASP page in the application: <%@ Language=VBScript %> <% Dim var var = Request.QueryString("var") ' do stuff Response.Redirect "nextpage.asp?var=" & var %> I know, I know, short and very dangerous. So we wrote some (en/de)coders and validation/verification routines: <%@ Language=VBScript %> <% Dim var var = Decode(Request.QueryString("var")) ' do stuff if isValid(var) then Response.Redirect "nextpage.asp?var=" & Encode(var) else 'throw error page end if %> And still Fortify flags this as vulnerable to Header Manipulation. How or what exactly is Fortify looking for? The reason I suspect that Fortify is looking for specific key words is that on the .Net side of things, I can include the Microsoft AntiXss assembly and call functions such as GetSafeHtmlFragment and UrlEncode and Fortify is happy. Any advice?

  • R ggplot2: Arrange facet_grid by non-facet column (and labels using non-facet column)

    - by tommy-o-dell
    I have a couple of questions regarding facetting in ggplot2... Let's say I have a query that returns data that looks like this: (note that it's ordered by Rank asc, Alarm asc and two Alarms have a Rank of 3 because their Totals = 1798 for Week 4, and Rank is set according to Total for Week 4) Rank Week Alarm Total 1 1 BELTWEIGHER HIGH HIGH 1000 1 2 BELTWEIGHER HIGH HIGH 1050 1 3 BELTWEIGHER HIGH HIGH 900 1 4 BELTWEIGHER HIGH HIGH 1800 2 1 MICROWAVE LHS 200 2 2 MICROWAVE LHS 1200 2 3 MICROWAVE LHS 400 2 4 MICROWAVE LHS 1799 3 1 HI PRESS FILTER 2 CLOG SW 1250 3 2 HI PRESS FILTER 2 CLOG SW 1640 3 3 HI PRESS FILTER 2 CLOG SW 1000 3 4 HI PRESS FILTER 2 CLOG SW 1798 3 1 LOW PRESS FILTER 2 CLOG SW 800 3 2 LOW PRESS FILTER 2 CLOG SW 1200 3 3 LOW PRESS FILTER 2 CLOG SW 800 3 4 LOW PRESS FILTER 2 CLOG SW 1798 (duplication code below) Rank = c(rep(1,4),rep(2,4),rep(3,8)) Week = c(rep(1:4,4)) Total = c( 1000,1050,900,1800, 200,1200,400,1799, 1250,1640,1000,1798, 800,1200,800,1798) Alarm = c(rep("BELTWEIGHER HIGH HIGH",4), rep("MICROWAVE LHS",4), rep("HI PRESS FILTER 2 CLOG SW",4), rep("LOW PRESS FILTER 2 CLOG SW",4)) spark <- data.frame(Rank, Week, Alarm, Total) Now when I do this... s <- ggplot(spark, aes(Week, Total)) + opts( panel.background = theme_rect(size = 1, colour = "lightgray"), panel.grid.major = theme_blank(), panel.grid.minor = theme_blank(), axis.line = theme_blank(), axis.text.x = theme_blank(), axis.text.y = theme_blank(), axis.title.x = theme_blank(), axis.title.y = theme_blank(), axis.ticks = theme_blank(), strip.background = theme_blank(), strip.text.y = theme_text(size = 7, colour = "red", angle = 0) ) s + facet_grid(Alarm ~ .) + geom_line() I get this.... Notice that it's facetted according to Alarm and that the facets are arranged alphabetically. Two Questions: How can I can I keep it facetted by alarm but displayed in the correct order? (Rank asc, Alarm asc). Also, how can I keep it facetted by alarm but show labels from Rank instead of Alarm? Note that I can't just facet on Rank because ggplot2 would see only 3 facets to plot where there are really 4 different alarms. Thanks kindly for the help! Tommy

  • Explicit casting doesn't work in default model binding

    - by Felix
    I am using ASP.NET MVC2 and Entity Framework. I am going to simplify the situation a little; hopefully it will make it clearer, not more confusing! I have a controller action to create address, and the country is a lookup table (in other words, there is a one-to-many relationship between Country and Address classes). Let's say for clarity that the field in the Address class is called Address.Land. And, for the purposes of the dropdown list, I am getting Country.CountryID and Country.Name. I am aware of Model vs. Input validation. So, if I call the dropdown field formLand - I can make it work. But if I call the field Land (that is, matching the variable in Address class) - I am getting the following error: "The parameter conversion from type 'System.String' to type 'App.Country' failed because no type converter can convert between these types." OK, this makes sense. A string (CountryID) comes from the form and the binder doesn't know how to convert it to Country type. So, I wrote the converter: namespace App { public partial class Country { public static explicit operator Country(string countryID) { AppEntities context = new AppEntities(); Country country = (Country) context.GetObjectByKey( new EntityKey("AppEntities.Countries", "CountryID", countryID)); return country; } } } FWIW, I tried both explicit and implicit. I tested it from the controller - Country c = (Country)"fr" - and it works fine. However, it never got invoked when the View is posted. I am getting the same "no type converter" error in the model. Any ideas how to hint to the model binder that there is a type converter? Thanks

  • Intellij Javafx artifact - how do you make it?

    - by Louis Sayers
    I've been trying all day to turn my javafx application into a jar file. I'm using Java 1.7 update 7. Oracle has some information, but it just seems scattered all over the place. Intellij is almost doing the job, but I get the following error: java.lang.NoClassDefFoundError: javafx/application/Application Which seems to say that I need to tell java where the jfxrt.jar is... If I add this jar to my classpath info for the manifest build in intellij - ctrl+shift+alt+s - Artifacts - Output Layout tab - Class Path, then I get another error: Could not find or load main class com.downloadpinterest.code.Main It seems strange to have to include jfxrt.jar in my class path though... I've tried to create an ant script as well, but I feel like IntelliJ is 90% of the way there - and I just need a bit of help to figure out why I need to include jfxrt.jar, and why my Main class isn't being found (I'm guessing I need to add it to the classpath somehow?). Could anyone clue me up as to what is happening? I had a basic gui before which worked fine, but JavaFX seems to be making life complicated!

  • Rhino Mocks, Dependency Injection, and Separation of Concerns

    - by whatispunk
    I am new to mocking and dependency injection and need some guidance. My application is using a typical N-Tier architecture where the BLL references the DAL, and the UI references the BLL but not the DAL. Pretty straight forward. Lets say, for example, I have the following classes: class MyDataAccess : IMyDataAccess {} class MyBusinessLogic {} Each exists in a separate assembly. I want to mock MyDataAccess in the tests for MyBusinessLogic. So I added a constructor to the MyBusinessLogic class to take an IMyDataAccess parameter for the dependency injection. But now when I try to create an instance of MyBusinessLogic on the UI layer it requires a reference to the DAL. I thought I could define a default constructor on MyBusinessLogic to set a default IMyDataAccess implementation, but not only does this seem like a codesmell it didn't actually solve the problem. I'd still have a public constructor with IMyDataAccess in the signature. So the UI layer still requires a reference to the DAL in order to compile. One possible solution I am toying with is to create an internal constructor for MyBusinessLogic with the IMyDataAccess parameter. Then I can use an Accessor from the test project to call the constructor. But there's still that smell. What is the common solution here. I must just be doing something wrong. How could I improve the architecture?

  • How do you clean Core Data generated models and code from a project?

    - by Hazmit
    I'm having an extremely annoying problem with Core Data in the iPhone SDK. I would say in general Core Data for the most part appears easy to use and nice to implement. I have a sqlite database that is being used as a read only reference to pull data elements out for an iPhone app. It would seem there are really mysterious issues relating to what seems to be migration of the database to the most recent versions of my schema. Why can't you just clean out your stored objects and models and let a project redo all of it when you compile next? You would think if you setup a stored object model there would be a way to just reset it and recompile. I've tried what feels like a thousand 'tips' that have been the results of hours of google searches and documentation prowling to figure out how to do this. My most recent error during compile time is below. 2010-04-07 18:23:51.891 PE[1962:207] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Can't merge models with two different entities named 'PElement'' All of this code has been working in the simulator and is only causing me troubles now because I made a change to the schema. I also have the database options for automatically migrating set as below. NSMutableDictionary *optionsDictionary = [NSMutableDictionary dictionary]; [optionsDictionary setObject:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption]; [optionsDictionary setObject:[NSNumber numberWithBool:YES] forKey:NSInferMappingModelAutomaticallyOption];

  • How can I find the song position of a song being played with XACT?

    - by DJ SymBiotiX
    So I'm making a game in XNA and I need to use XACT for my songs (rather than media player). I need to use XACT because each song will have multiple layers that combine when played at the same time (bass, lead, drums) etc. I cant use the media player because the media player can only play one song at a time. Anyways, so lets say I have a song playing with XACT in my project with the following code public SongController() { audioEngine = new AudioEngine(@"Content\Song1\Song1.xgs"); waveBank = new WaveBank(audioEngine, @"Content\Song1\Layers.xwb"); soundBank = new SoundBank(audioEngine, @"Content\Song1\SongLayers.xsb"); songTime = new PlayTime(); Vox = soundBank.GetCue("Vox"); BG = soundBank.GetCue("BG"); Bass = soundBank.GetCue("Bass"); Lead = soundBank.GetCue("Lead"); Other = soundBank.GetCue("Other"); Vox.SetVariable("CueVolume", 100.0f); BG.SetVariable("CueVolume", 100.0f); Bass.SetVariable("CueVolume", 100.0f); Lead.SetVariable("CueVolume", 100.0f); Other.SetVariable("CueVolume", 100.0f); _bassVol = 100.0f; _voxVol = 100.0f; _leadVol = 100.0f; _otherVol = 100.0f; Vox.Play(); BG.Play(); Bass.Play(); Lead.Play(); Other.Play(); } So when I look at the variables in Vox, or BG (they are Cue's btw) I cant seem to find any play position in them. So I guess the question is: Is there a variable I can query to find that data, or do I need to make my own class that starts counting up from the time I start the song? Thanks

  • alphanumeric and special character sorting

    - by Kaushik Gopal
    Hi ppl, I wanted to know the different standards of sorting. To be more specific take the sample set: (Please note there's capitals, small letters, special characters, null values and numbers here) A a 3F Zx - 1Ad NULL How would the Oracle Database sort this by default? How would LINQ sort this by default? How would db2 sort this by default? (the following may get even more vague) How does the Windows platform sort this? (I mean say you have a couple of filenames, by default how would this get treated in a name sort) How does the *nix platform sort this? Is there some sort of standard for alphanumeric/special character sorting? The Windows operating system orders with numbers first, then alphabets. The Oracle database however treats alphabets first. I'm not sure of the *nix platform. It would be nice to have one place to know all these rules for the most common platforms (listed in questions above). Would the gurus throw some light on this topic? Cheers, K

  • How to insert inline content from one FlowDocument into another?

    - by Robert Rossney
    I'm building an application that needs to allow a user to insert text from one RichTextBox at the current caret position in another one. I spent a lot of time screwing around with the FlowDocument's object model before running across this technique - source and target are both FlowDocuments: using (MemoryStream ms = new MemoryStream()) { TextRange tr = new TextRange(source.ContentStart, source.ContentEnd); tr.Save(ms, DataFormats.Xaml); ms.Seek(0, SeekOrigin.Begin); tr = new TextRange(target.CaretPosition, target.CaretPosition); tr.Load(ms, DataFormats.Xaml); } This works remarkably well. The only problem I'm having with it now is that it always inserts the source as a new paragraph. It breaks the current run (or whatever) at the caret, inserts the source, and ends the paragraph. That's appropriate if the source actually is a paragraph (or more than one paragraph), but not if it's just (say) a line of text. I think it's likely that the answer to this is going to end up being checking the target to see if it consists entirely of a single block, and if it does, setting the TextRange to point at the beginning and end of the block's content before saving it to the stream. The entire world of the FlowDocument is a roiling sea of dark mysteries to me. I can become an expert at it if I have to (per Dostoevsky: "Man is the animal who can get used to anything."), but if someone has already figured this out and can tell me how to do this it would make my life far easier.

  • JQuery Ajax error handling, show custom exception messages

    Hey Folks, I am wondering if there is some way where I can show custom exception messages as an alert in my Jquery ajax error message. For example, say if I want to throw an exception in server side via Struts by "throw new ApplicationException("User name already exists");", I want to catch this message(User name already exists) in Jquery ajax error message. jQuery("#save").click(function(){ if(jQuery('#form').jVal()){ jQuery.ajax({ type: "POST", url: "saveuser.do", dataType:"html", data:"userId="+encodeURIComponent(trim(document.forms[0].userId.value)), success:function(response){ jQuery("#usergrid").trigger("reloadGrid"); clear(); alert("Details saved successfully!!!"); }, error:function (xhr, ajaxOptions, thrownError){ alert(xhr.status); alert(thrownError); } }); } } ); On the second alert where I alert thrown error, I am getting undefined and the status code is 500. I am not sure where I am going wrong. Please let me know on this. Thanks, Dukes

  • Kohana 3: How to find the active item in a dynamic menu

    - by Svish
    Maybe not the best explanation, but hear me out. Say I have the following in a config file called menu.php: // Default controller is 'home' and default action is 'index' return array( 'items' => array( 'Home' => '', 'News' => 'news', 'Resources' => 'resources', ), ); I now want to print this out as a menu, which is pretty simple: foreach(Kohana::config('menu.items') as $title => $uri) { echo '<li>' . HTML::anchor($uri, $title) . '</li>'; } However, I want to find the $uri that matches the current controller and action. And if the action is the default one or not. What I want to end up with is that menu item should have id="active-item" if it is the linking to the current controller, but the default action. And id="active-subitem if it is linking to the current controller and the action is not the default one. Hope that made sense... Anyone able to help me out here? Both in how to do this in Kohana 3 and also how it should be done in Kohana 3. I'm sure there are lots of ways, but yeah... any help is welcome :) Examples: domain.com -- Home should be active-item since it is the default controller domain.com/home -- Home should be active-item domain.com/home/index -- Home should be active-item since index is the default action domain.com/resources -- Resources should be active-item domain.com/resources/get/7 -- Resources should be active-subitem since get is not the default action

  • Design Patterns Recommendation for Filtering Option

    - by Tarik
    Hi people, I am thinking to create a filter object which filters and delete everything like html tags from a context. But I want it to be independent which means the design pattern I can apply will help me to add more filters in the future without effecting the current codes. I thought Abstract Factory but it seems it ain't gonna work out the way I want. So maybe builder but it looks same. I don't know I am kinda confused, some one please recommend me a design pattern which can solve my problem but before that let me elaborate the problem a little bit. Lets say I have a class which has Description field or property what ever. And I need filters which remove the things I want from this Description property. So whenever I apply the filter I can add more filter in underlying tier. So instead of re-touching the Description field, I can easily add more filters and all the filters will run for Description field and delete whatever they are supposed to delete from the Description context. I hope I could describe my problem. I think some of you ran into the same situation before. Thanks in advance...
