  • In Entity framework, we can use Model first, DB first, Code first but how can we create table programmatically

    - by AukI
    In entity framework we can use 3 approaches model first , code first , database first but each one of them needs manual hand touch(means creating database or create model or write the POCO class codes or entity class codes) before proceeding to the next step ( using EF in context ). What if I want to create database and tables and table relationships programatically and still want to have to features of EntityFramework 4.3. To be more specific , from this example http://support.microsoft.com/kb/307283 we can create database , tables and everything using SQL command but we can't have the advantages of entity framework. So if we want to have that what should we do?

  • Automatically decorating every instance method in a class

    - by max
    I want to apply the same decorator to every method in a given class, other than those that start and end with __. It seems to me it should be doable using a class decorator. Are there any pitfalls to be aware of? Ideally, I'd also like to be able to: disable this mechanism for some methods by marking them with a special decorator enable this mechanism for subclasses as well enable this mechanism even for methods that are added to this class in runtime [Note: I'm using Python 3.2, so I'm fine if this relies on features added recently.] Here's my attempt: _methods_to_skip = {} def apply(decorator): def apply_decorator(cls): for method_name, method in get_all_instance_methods(cls): if (cls, method) in _methods_to_skip: continue if method_name[:2] == `__` and method_name[-2:] == `__`: continue cls.method_name = decorator(method) return apply_decorator def dont_decorate(method): _methods_to_skip.add((get_class_from_method(method), method)) return method Here are things I have problems with: how to implement get_all_instance_methods function not sure if my cls.method_name = decorator(method) line is correct how to do the same to any methods added to a class in runtime how to apply this to subclasses how to implement get_class_from_method

  • Do I need to change the package name for the free version of my app?

    - by teedyay
    I have an application that I'm going to publish to the Android market. I'm planning on releasing a paid-for version and a free version with restricted feature set. During development I've ensured I can turn features on and off by setting a few constant values, so I only have one codebase. However, now I come to release I'm not clear if I need to make a copy of the app with a different package name for the free version. The documentation on how the market works say updates will only be recognised if they have the same package name and are signed with the same key. Does this mean it's OK to release two applications with the same package name but signed with different keys, or will this break something? Or is it just bad practice?

  • Looking for suggestions about an architecture of a MultiThreaded app.

    - by Dimitri
    Hello everyone. I am looking to develop a multithreaded application that will be running in unconditional loop and processing high volume of data. High volume is 2000+ records per minute. Processing will involve data retrieval, calculations and data updates. I need the application to perform so that there is virtually no back log, meaning i need to be able to finish up all of the 2000 points in one minute or even faster. Our current implementation features a multithreaded application that is spawn multiple times (from 10 to 20) and we are noticing that it's not handling data as expected and i even feel that instances of the application compete with each other for processor time and eventually if not slowing, not benefiting each other for sure. I would like to know what would be the best approach: have a single instance running but maximize threads that can run simultaneously? or is there other ways i don't know? I'm open to suggestions. Thank you in advance

  • Dynamic Button Layout without hard coding positions

    - by mmc
    I would like to implement a view (it will actually be going into the footer of a UITableView) that implements 1-3 buttons. I would like the layout of these buttons (and the size of the buttons themselves) to change depending on which ones are showing. An example of almost the exact behavior I would want is at the bottom of the Info screen in the Contacts application when you are looking at a specific contact ("Add to Favorites" disappears when it is clicked, and the other buttons expand to take up the available space in a nice animation). As I'm running through the different layout scenarios, I'm hard coding all these values and I just think... "this is NOT the way I'm supposed to be doing this." It even APPEARS that Interface Builder has some features that may do this for me in the ruler tab, but I'll be darned if I can figure out how they work (if they work) on the phone. Does anyone have any suggestions, or a tutorial online that I could look at to point me in the right direction? Thanks much.

  • Google Chrome "window.open" workaround?

    - by McBonio
    Hi Folks! I have been working on a web app and for part of it I need to open a new window. I have this working on all browsers, my sticking point is with Google Chrome. Chrome seems to ignore the window features which is causing me issues, the thing I'm struggling with is I need the address bar to be editable within the new window. FF, IE, Safari and Opera do this fine, Chrome does not. My Code: <script language="javascript" type="text/javascript"> <!-- function popitup(url) { newwindow=window.open(url,'name','toolbar=1,scrollbars=1,location=1,statusbar=0,menubar=1,resizable=1,width=800,height=600'); if (window.focus) {newwindow.focus()} return false; } // --> </script> Any help would be gratefully received! Thanks in advance :)

  • How to tell if a user updated my app or installed a new one

    - by user310318
    I need a way to tell if the app being used by a user is a fresh new install (new user), or was a pre-existing user who updated. The previous app version did not track UDID's, and didn't save anything (it just ran as a simple app). Is there a way for an update to tell if the user previously installed the app? Even if that app didn't save anything into the documents folder, and the app didnt communicate with a server (UDID post)? (id like to be able to offer bonus features to my existing loyal users who had already installed the original app and updated) thanks!!

  • How do I escape a string for a shell command in nodejs (V8 Javascript engine)?

    - by Maciek
    In nodejs, the only way to execute external commands is via sys.exec(cmd). I'd like to call an external command and give it data via stdin. In nodejs there does yet not appear to be a way to open a command and then push data to it (only to exec and receive its standard+error outputs), so it appears the only way I've got to do this right now is via a single string command such as: var dangerStr = "bad stuff here"; sys.exec("echo '" + dangerStr + "' | somecommand"); Most answers to questions like this have focused on either regex which doesn't work for me in nodejs (which uses Google's V8 Javascript engine) or native features from other languages like Python. I'd like to escape dangerStr so that it's safe to compose an exec string like the one above. If it helps, dangerStr will contain JSON data.

  • C99 strict aliasing rules in C++ (GCC)

    - by Checkers
    As far as I understand, GCC supports all of its C99 features in C++. But how is C99 strict aliasing handled in C++ code? I know that casting with C casts between unrelated types is not strict-aliasing-safe and may generate incorrect code, but what about C++? Since strict aliasing is not part of C++ standard (is that correct?), GCC must be specifying the semantics itself. I figure const_cast and static_cast cast between related types, hence they are safe, while reinterpret_cast can break strict aliasing rules. Is this a correct understanding?

  • Is there a fast concat method for linked list in Java?

    - by rocker
    How can I concat two linked lists in O(1) with Java via jdk, google or apache commons collection or whatever? E.g. in jdk there is only the addAll method which is O(n). Another feature I miss is to concat two lists where each of them could be in inverse order. To illustrate this assume two lists a-b-c and e-f-g could merged into a-b-c-e-f-g a-b-c-g-f-e c-b-a-e-f-g c-b-a-g-f-e Do you know of such a list implemenation or do I have to implement my own linked list? It would be also helpful to know how to tweak existing solutions (e.g. the jdk LinkedList has a lot of private methods only). These features seems to me very obvious, hopefully I am not missing something stupid.

  • Are ASP.NET readymade controls really production worthy ?

    - by Anil Namde
    I have come across the ASP.NET ready made controls like grid, repeater... etc. For example while dealing with GRID i remember following facts, ASP.NET V1.1 has DataGrid with "virtual row count" which is heavily used for custom paging which is need of big sites to perform well. ASP.NET V2.0 added the GridView with all sort of cool features but also split the DataSource parts as different component. Also "virtual row count" is not supported and for pagination to be done DataSource control is need to be used. After all these thing i thought that ASP.NET control are not made to be used as is for the development. Please let me know whether i am right or wrong? Also if you think i am wrong PLEASE provide inputs/links which can help me come out of this thinking of mine.

  • RSpec setup for an application that depends on an external database from another application.

    - by Chris Rittersdorf
    I've had to add features to an application that depends on a database from another application. I've been able to set up a connection to this external database and pull data from it. However, I'm not sure how to get my main application to create a test database for this external application. It would be awesome if there some way to pull in the schema for this database and create it in the same manner that 'rake db:test:prepare' does. Is there any configuration capabilities for RSpec to do this, or will I have to roll my own task?

  • CodeIgniter Production and Developpement server on the same domain. (no subdomain)

    - by Onigoetz
    Hi, I googled this many times but now I have to ask it here. I want to make a workflow for a website for Developpement/Production. My constraint is that I use Facebook Connect (Facebook Graph now) so I need to have the dev and prod on the same domain and server. (to be able to log in and test the features) I thought I will edit the CodeIgniter Index.php to redirect if I have a specific user agent (I can edit the one of my firefox) You think it's a good Idea or you have a better one ? And now comes the eternal question : how can I deploy this the easy way ? should I use Capistrano or Phing ? or simply a script with SVN ? Please help me, I'm totally new to this Deployment thing. I used to work directly in production for my little websites or on other domains. but now it's not possible anymore.

  • Are there any GOOD javascript addins for Visual Studio?

    - by Jeremy B.
    In our daily work we maintain some rather large Javascript libaries. We use VS2008 and while they made some improvements to the Javascript IDE, I still find it lacking. There is no outlining, no collapsing, or other ways to keep the code organized. I have tried js-addin and JSLint which crash and don't have the features I want, respectively. I have actually gone as far as running Aptana Studio as their Javascript IDE is much better than what I can get out of Visual Studio. I'm getting tired of having to maintain 2 IDE's. Is there anything out there that can make Javascript editing less painful in Visual Studio 2008? (We don't have the option of 2010 yet).

  • What wiki tools exist to generate shippable user doc from a wiki?

    - by tletnes
    I am looking into using a wiki (prefer mediawiki, but not a req.) as the repository for developer generated documentation (User Guides, Release Notes, Application Notes, Errata, etc.) from a collaborative/easy-to-update point of view a wiki seems like a good match, however since this documentation will ultimately ship to customers we want to be able to export the documents in their final state (e.g. during the release cycle) to static versions that no longer include histories. Ideally the export would leave the document n a form where errors could be easily fixed by a non-programmer It would be good if niceties like section ordering and table of contents were available, or easy to add after the fact. Are any tools with features like these avalible?

  • What are the alternatives for Java authentication?

    - by Crusader
    Preferably something that integrates well with a Flex front end. Yes the Spring Security guys say this is possible, but all examples seem to use legacy jsp tag libraries making them half useless as examples. I don't want to spend a month setting up and learning how to use a security tool. I would like a tool which supports using annotations (@RolesAllowed etc), MINIMAL XML, and 'remember-me' features (not cookie based). Apache Shiro seems to support Flex/Silverlight/Swing as well but I'd like to know if there are any other alternatives that are NOT container specific.

  • How do I remove duplicate SQL Server 2008 instances after upgrading from SQL Server 2005?

    - by andypike
    I've just upgraded an existing SQL Server 2005 to 2008 by running the installer (not the platform installer). It all seems to have worked - there were no errors reported and my code that connects to these databases still works fine. The problem is, when I try installing SQL Server Management Studio Express 2008 I am shown then following error message when I select to add new features to an existing instance of SQL Server 2008: The SQL Server instance 'SQL1MINUS102' already has an Instance ID '2' that is different than the specified Instance ID 'SQL1MINUS102'. Specifying more than one instance ID for the same SQL Server instance is not supported. Here is a screenshot of the installation dialog and the setup discovery report: Screenshot Notice that there are two instances with the same name. So any ideas how I should recifiy this so that I can install Management studio? Thanks in advance

  • How can I detect when the .NET Framework feature is "turned off" in Windows 7 / Vista?

    - by John Myczek
    My application requires the .NET Framework version 3.5. I recently ran into a customer that had the .NET Framework installed but turned off on Windows Vista (also applies to Windows 7). In this case, my installer (InstallShield 2009) does not prompt the user to install the Framework (because it is already installed) and when my application runs it crashes immediately. I tried another .NET application and it also crashes immediately. Is there any way to detect this situation and handle it more gracefully? Just detecting this during install is not ideal since the .NET Framework can be turned off at any time. Ideally, the application would be able to check and display a friendly message to the user telling them they need to turn on the .NET Framework. EDIT: "Turning off" the .NET Framework in Windows Vista or Windows 7 is not the same as uninstalling it. The Framework can be simply turned back on without reinstalling: http://windows.microsoft.com/en-US/windows-vista/Turn-Windows-features-on-or-off

  • What frameworks should we consider for a custom web application?

    - by justkevin
    A client is looking for a custom web application, which will eventually include lots of interconnected components, but the main features are: Subscription based membership as well as virtual/digital product sales Members have their own public web cookie-cutter directories (e.g., storefronts, pages, etc.) and personal member admin area. Site administrators will need both common tools (member admin, password changes, etc.) and custom tools that can be readily developed or integrated with 3rd party solutions. What frameworks should we be looking at? PHP/MySQL is preferable unless something really outstanding is available in another stack.

  • Which messaging services can BlackBerry apps integrate with?

    - by humble coffee
    I'm in charge of having a BlackBerry app developed that translates the contents of a message from one language to another. So the aim would be to have a button at the bottom of a received message which says 'translate this'. I've heard that this kind of thing is possible using J2ME plus the native BlackBerry API. Can this be done for all kinds of messanging features on the Blackberry, or just some? ie I'm thinking SMS, email and BB messages. Secondly, given that the translation itself is done via a web request, I feel like this should be a fairly lightweight application. Would anyone care to hazard a guess how long it might take an experienced contractor to develop such an app?

  • CodeIgniter version 2.0 is stable enough to use?

    - by ajsie
    i want to port my application to CodeIgniter but i am wondering whether i should use their v2.0 or v1.72 (then when they release 2.0, upgrade it). i have never used a framework before so i don't exactly know what implies when upgrading a framework: what does it mean practically - i just move the folders and it will work? or do i have to change a lot of settings, file structure etc? could someone enlighten me about the upgrade process. and what would you use: v.1.72 or v2.0? if i'm using the latest version, is there a good documentation for it somewhere so you can read about how to use the new features: packages, drivers and so on. thanks

  • Web and stand-alone apps development tendency

    - by Narek
    There is a strong tendency of making web apps and even seems that very soon a lot of features will be available online so that for every day use people will have all necessary software free online and they will not need to install any software locally. Only specific (professional) tools that usually people don’t use at home will not be available as a web app. So my question, how do you imagine selling software that was necessary for everyday use and was not free (seems they can't make money any more by selling their product – no need of those products). And what disadvantages have web apps, that is to say, what is bad to use software online compared with having the same software locally (please list)? Please do not consider this question not connected with programming, as I really would like to have a little statistics from professional programmers who are aware from nowday’s tendency of software and programming. Thanks.

  • What's an elegant solution to get the property values from two classes (that have the same property

    - by SlipToFall
    Essentially I have to deal with a poorly implemented web service. They have two classes that don't derive from a parent class, but have the same properties (Ughh...). So it looks like this in my web service proxy class file: public partial class Product1 { public int Quantity; public int Price; } public partial class Product2 { public int Quantity; public int Price; } So what's the best way to grab the values from known properties without duplicating the code and casting to their respective classes? I know I probably could use reflection, but that can get ugly. If there is an easier less crazier way to do it (maybe in the new c# features?) please let me know.

  • Managing multiple blogs (wordpress) from one control panel

    - by thisMayhem
    This is the deal: I have more than one blog (not running yet) that I want to install in subfolders for one of my domains. Each blog will obviously have its own look and feel and content. I could just have a set of control panels and administer them individually or I could somehow manage them form a single control panel. Issues I've come across are: Some plugins offer this functionality while suppressing other features like auto draf saving, in-post category and tag creation, image upload etc. I'm not necessarily looking for a ready solution, more like some guidance on how to approach this particular problem in the best possible manner. I'm looking for a fully working scenario, not some plugin that allows me to more or less simulate the one-blog-administration experience.
