  • MVC, can model save/load its data?

    - by fuzzygoat
    Quick question, my data model is a singleton object and it contains a list of names I want archive. My idea is to make the model responsible for loading / saving this data. The ModelLoad will then be called by the ViewControllerviewDidLoad and the ModelSave by ViewControllerapplicationWillTerminate. I could do the load / save directly within the ViewController, but this would be messy as the list of names are on instance variable of the model. gary

  • How are DynamicResources built? Use in contextmenus.

    - by miguel
    Are dynamic resources truly dynamic? If I define a DynamicResource, I realise that an expression is created (where?) that is not translated into a resource until runtime, however, What I do not understans is whether this dynamicresouce, once built, is now "Static" For instance, if I create a context menu via a dynamicresource, are the menuitems which are created at runtime on access then static, even if they are bound? If so, how can i create a dynamic context menu in XAML?

  • polymorphism and interfaces

    - by mixm
    if i have two classes x and y, both extend class w. and x implementing interface z. if i have methods doSomething(w object) and doSomething(x object), what would happen if i call doSomething(x)? edit: im implementing this on java, more specifically on android. im asking this because some classes which implement a specific interface mostly does the same thing when doSomething() is called. but there are special cases which i would like to single out.

  • Is it possible to merge two MySQL databases into one?

    - by Mike L.
    Lets say I have two MySQL databases with some complex table structures. Neither database has the same table name. Lets say these tables contain no rows (they do but I could truncate the tables, the data is not important right now, just testing stuff). Lets say I need these 2 databases merged into one. For instance: DB1: cities states DB2: index subindex posts I want to end up with a single DB that contains: cities states index subindex posts Is this possible?

  • How can the AssemblyName class be used for existing Assembly's?

    - by IbrarMumtaz
    This is another exam related question. I want to know how can I use the AssemblyName class to represent an existing assembly that already exists on disk??? I am talking about from the perspective of using the AppDomain's instance method .Load(), that takes an AssemblyName object as a parameter. I know what MSDN has to say about what the .Load() method was designed for but that aside, I still want to know how to use it !!!

  • jQuery toggling divs, expand collapse all and keep first item selected when page loads

    - by hollyb
    Hi, I have a question about some functionality I'm trying to add to my jQuery to enable a button or text to expand/contract all the divs on click... and I'd like to figure out how to keep the first div open when the page loads. Here is the jQuery: (document).ready(function(){ //Hides containers on load $(".toggle_container").hide(); //Switch "Open" and "Close" state on click $("h2.trigger").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); //Slide up and down on click $("h2.trigger").click(function(){ $(this).next(".toggle_container").slideToggle("slow"); }); }); And the css: // uses a background image with an on (+) and off (-) state stacked on top of each other h2.trigger { background: url(buttonBG.gif) no-repeat;height: 46px;line-height: 46px;width: 300px;font-size: 2em;font-weight: normal;} h2.trigger a {color: #fff;text-decoration: none; display: block;} h2.active {background-position: left bottom;} .toggle_container { overflow: hidden; } .toggle_container .block {padding: 20px;} And the html <h2 class="trigger"><a href="#">Heading</a></h2> <div class="toggle_container"> <div class="block">Stuff goes here</div> </div> <h2 class="trigger"><a href="#">Heading 2</a></h2> <div class="toggle_container"> <div class="block">Stuff goes here</div> </div> So it works great and looks great. However, when I try to get it to keep the first instance open, the background image that should adjust show the (-) state doesn't change. The code I used to this was: $(".toggle_container:first").show(); So, my question is, does anyone know of an easier way to show the first instance of this as open without having to created specials rules/class for the first item? Also, any ideas about how to make an open all/close all link? Thanks!

  • how to send parameters to a web Services via SOAP?

    - by Alejandra Meraz
    Before I start: I'm programming for Iphone, using objective C. I have already implemented a call to a web service function using NSURLRequest and NSURLConnection and SOAP. The function then returns a XML with the info I need. The code is as follows: NSString *soapMessage = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" "<soap:Body>\n" "<function xmlns=\"http://tempuri.org/\" />\n" "</soap:Body>\n" "</soap:Envelope>\n"]; NSURL *url = [NSURL URLWithString:@"http://myHost.com/myWebService/service.asmx"]; //the url to the WSDL NsMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]]; [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Lenght"]; [theRequest setHTTPMethod:@"POST"]; [theRequest addValue:@"myhost.com" forHTTPHeaderField:@"Host"]; [theRequest addValue:@"http://tempuri.org/function" forHTTPHeaderField:@"SOAPAction"]; [theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; I basically copy and modified the soap request the web service gave as an example. i also implemented the methods didRecieveResponse didRecieveAuthenticationChallenge didRecievedData didFailWithError connectionDidFinishLoading. And it works perfectly. Now I need to send 2 parameters to the function: "location" and "module". I tried modifying the soapMessage like this: NSString *soapMessage = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" "<soap:Body xmlns=\"http://tempuri.org/\" />\n" "<m:GetMonitorList>\n" "<m:location>USA</m:location>\n" "<m:module>DEVELOPMENT</m:module>\n" "</m:GetMonitorList>\n" "</soap:Body>\n" "</soap:Envelope>\n"]; But is not working...any thoughts how should I modify it? Extra info: it seems to be working... kind of. But the webservice return nothing. During the connection, the method didReceiveResponse execute once and the didFinishLoading method executes as well. But not even once the method didReceiveData. I wonder if, even though there is no USA locations, it will still send at least something? is there a way to know which are the parameters the function is waiting for? I don't have access to the source of the webservice but i can access the WSDL.

  • Rhino Mocks - Do we really need stubs?

    - by Marcelo Oliveira
    If it's possible to change mock behaviour in Rhino Mocks using mock.Stub().Return(), why do we need Stubs anyway? What do we lose by always using MockRepository.GenerateMock()? One big benefit of using Mocks instead of Stubs is that we will be able to reuse the same instance among all the tests keeping them cleaner and straightforward. The moq framework works in a similar way... we don't have different objects for mocks and stubs. (please, don't answer with a link to Fowler's "Mocks aren't stubs" article)

  • Using jquery to prevent resubmitting form

    - by Tony
    I use jquery's .submit() to intercept user's submit event, however I found a problem. When the user single click the submit button, the form is submitted normally, but if a user deliberately fast click it multiple times, it will submit multiple times, which will cause duplicated data in the database. What's the solution for this kind of problem ?

  • How to write backwards compatible HTML5 ?

    - by Olivier Lalonde
    I'd like to start using HTML5's basic features, but at the same time, keep my code backwards compatible with older browsers (graceful degradation). For instance, I'd like to use the cool CSS3 properties for making rounded corners. Is there any available tutorial for writing gracefully degradable HTML5 ? Additionally, what browsers should I support so that my app. is functional for at least 95% of visitors? What are the ways to test those browsers painlessly ?

  • DUMP in unhandled C++ exception

    - by Jorge Vasquez
    In MSVC, how can I make any unhandled C++ exception (std::runtime_error, for instance) crash my release-compiled program so that it generates a dump with the full stack from the exception throw location? I have installed NTSD in the AeDebug registry an can generate good dumps for things like memory access violation, so the matter here comes down to crashing the program correctly, I suppose. Thanks in advance.
