  • What's the best way to keep java app data stored redundantly in a file?

    - by Bijan
    If I have systems that are based on realtime data, how can I ensure that all the information that is current is redundantly stored in a file? So that when the program starts again, it uses this information to initialize itself back to where it was when it closed. I know of xstream and HSQLDB. but wasn't sure if this was the best option for data that needs to be a literal carbon copy.

  • Cannot render javascript from controller

    I want to display a modal window with an error message, when the user has entered something invalid in a form, but render another action if everything is ok. However, when I try to display the modal window with render :js => "jQuery.facebox(#{...})" only the actual javascript called is displayed: try { jQuery.facebox(...) } catch (e) { alert('RJS error:\n\n' + e.toString()); alert('jQuery.facebox(\"<div class=\'error\'>Error</div>\")'); throw e }

  • Displaying success/failure messages from hidden iframe submit

    - by Erik Nelson
    I'm using the hidden iframe method to submit a form with a file upload field. I want to display a message back on the page using javascript and I'm not sure how to do this. If this was just a form with text fields I'd do an AJAX post and respond with a message I'd display in my callback function. I'm just not sure how to accomplish this same task with the hidden iframe method since it is a standard form post.

  • Rails MVC Best Practices for Website Modules

    I am just beginning to build my Rails application and thus far I've followed a RESTful design and it's proven much easier to understand and organize the code and structure of the application. I have things like posts and comments. However for the front page. I want to display all the latest posts but also may be in the sidebar display things such as Latest Comments and Latest events. What's the best way to go about this while maintaining the RESTful philosophy?

  • How to change subnet mask and DHCP enabled flag in C++ and Windows XP

    - by Don
    Does anyone know how to change the subnet mask and the DHCP enabled flag on Windows XP / Vista / 7 from a C++ program? The Windows API has a GetAdaptersInfo() routine which will give you that information, but I need the counterpart SetAdaptersInfo() which doesn't seem to exist. I've looked all over MSDN and the web and don't see how to do it on newer-than-Windows-NT machines. Any information is greatly appreciated.

  • Using pointers, references, handles to generic datatypes, as generic and flexible as possible

    - by Patrick
    In my application I have lots of different data types, e.g. Car, Bicycle, Person, ... (they're actually other data types, but this is just for the example). Since I also have quite some 'generic' code in my application, and the application was originally written in C, pointers to Car, Bicycle, Person, ... are often passed as void-pointers to these generic modules, together with an identification of the type, like this: Car myCar; ShowNiceDialog ((void *)&myCar, DATATYPE_CAR); The 'ShowNiceDialog' method now uses meta-information (functions that map DATATYPE_CAR to interfaces to get the actual data out of Car) to get information of the car, based on the given data type. That way, the generic logic only has to be written once, and not every time again for every new data type. Of course, in C++ you could make this much easier by using a common root class, like this class RootClass { public: string getName() const = 0; }; class Car : public RootClass { ... }; void ShowNiceDialog (RootClass *root); The problem is that in some cases, we don't want to store the data type in a class, but in a totally different format to save memory. In some cases we have hundreds of millions of instances that we need to manage in the application, and we don't want to make a full class for every instance. Suppose we have a data type with 2 characteristics: A quantity (double, 8 bytes) A boolean (1 byte) Although we only need 9 bytes to store this information, putting it in a class means that we need at least 16 bytes (because of the padding), and with the v-pointer we possibly even need 24 bytes. For hundreds of millions of instances, every byte counts (I have a 64-bit variant of the application and in some cases it needs 6 GB of memory). The void-pointer approach has the advantage that we can almost encode anything in a void-pointer and decide how to use it if we want information from it (use it as a real pointer, as an index, ...), but at the cost of type-safety. Templated solutions don't help since the generic logic forms quite a big part of the application, and we don't want to templatize all this. Additionally, the data model can be extended at run time, which also means that templates won't help. Are there better (and type-safer) ways to handle this than a void-pointer? Any references to frameworks, whitepapers, research material regarding this?

  • Dynamic Multiple Choice (Like a Wizard) - How would you design it? (e.g. Schema, AI model, etc.)

    - by henry74
    This question can probably be broken up into multiple questions, but here goes... In essence, I'd like to allow users to type in what they would like to do and provide a wizard-like interface to ask for information which is missing to complete a requested query. For example, let's say a user types: "What is the weather like in Springfield?" We recognize the user is interested in weather, but it could be Springfield, Il or Springfield in another state. A follow-up question would be: What Springfield did you want weather for? 1 - Springfield, Il 2 - Springfield, Wi You can probably think of a million examples where a request is missing key data or its ambiguous. Make the assumption the gist of what the user wants can be understood, but there are missing pieces of data required to complete the request. Perhaps you can take it as far back as asking what the user wants to do and "leading" them to a query. This is not AI in the sense of taking any input and truly understanding it. I'm not referring to having some way to hold a conversation with a user. It's about inferring what a user wants, checking to see if there is an applicable service to be provided, identifying the inputs needed and overlaying that on top of what's missing from the request, then asking the user for the remaining information. That's it! :-) How would you want to store the information about services? How would you go about determining what was missing from the input data? My thoughts: Use regex expressions to identify clear pieces of information. These will be matched to the parameters of a service. Figure out which parameters do not have matching data and look up the associated question for those parameters. Ask those questions and capture answers. Re-run the service passing in the newly captured data. These would be more free-form questions. For multiple choice, identify the ambiguity and search for potential matches ranked in order of likelihood (add in user history/preferences to help decide). Provide the top 3 as choices. Thoughts appreciated. Cheers, Henry

  • UIWebView or Custom UIView

    - by dinoc
    I have a dilemma and was wondering if anyone else had this issue. I have a Navigation based app that when you drill down to the last level, that last view has lots and lots of information and details. I am wondering if I should just use a UIWebView to display the details of information or if I should create a custom UIView with all the labels and outlets set in that UIView. Which way is recommended or the preferred way of doing something like this?

  • Dynamically refresh JTextArea as processing occurs?

    - by digiarnie
    I am trying to create a very simple Swing UI that logs information onto the screen via a JTextArea as processing occurs in the background. When the user clicks a button, I want each call to: textArea.append(someString + "\n"); to immediately show up in the UI. At the moment, the JTextArea does not show all log information until the processing has completed after clicking the button. How can I get it to refresh dynamically?
