  • C# Sql Connection Best Practises 2013

    - by Pete Petersen
    With the new year approaching I'm drawing up a development plan for 2013. I won't bore you with the details but I started thinking about whether the way I do things is actually the 'correct' way. In particular how I'm interfacing with SQL. I create predominantly create WPF desktop applications and often some Silverlight Web Applications. All of my programs are very Data-Centric. When connecting to SQL from WPF I tend to use Stored Procedures stored on the server and fetch them using ADO.NET (e.g. SQLConnection(), .ExecuteQuery()). However with Silverlight I have a WCF service and use LINQ to SQL (and I'm using LINQ much more in WPF). My question is really is am I doing anything wrong in a sense that it's a little old fashioned? I've tried to look this up online but could find anything useful after about 2010 and of those half were 'LINQ is dead!' and the other 'Always use LINQ' Just want to make sure going forward I'm doing the right things the right way, or at least the advised way :). What principles are you using when connecting to SQL? Is it the same for WPF and Silverlight/WCF?

  • observing multiple select menus with prototype

    - by snaken
    Hi, I want to observe multiple select menus and respond to their changes using prototype but only the first menu seems to be observed. This is my code: $('product_options').select('select').invoke("observe","change",optchange); If there are - for example - 3 selects within product_options then it only observes the first, i thought it might be because of invoke so i then tried this: $('product_options').select('select').each(function(sel){ $(sel).observe("change",optchange); }); Still doesnt work though, any ideas whats wrong?

  • How can I animate multiple elements sequentially using jQuery?

    - by lorenzium
    I thought it would be simple but I still can't get it to work. By clicking one button, I want several animations to happen - one after the other - but now all the animations are happening at once. Here's my code - can someone please tell me where I'm going wrong?: $(".button").click(function(){ $("#header").animate({top: "-50"}, "slow") $("#something").animate({height: "hide"}, "slow") $("ul#menu").animate({top: "20", left: "0"}, "slow") $(".trigger").animate({height: "show", top: "110", left: "0"}, "slow"); });

  • How to disable a YUI MenuBarItem from markup

    - by Bears will eat you
    I prefer creating my nav menus from markup (rather than Javascript), like in this example. Is it possible to create menus and/or menu items from markup which are disabled? I see how to use Javascript to do this (use the disabled config property), but I'm looking for some way to encode this information in markup - perhaps there's a CSS class to use? Or am I out of luck here?

  • C++ gdb GUI

    - by HappyDude
    Briefly: Does anyone know of a GUI for gdb that brings it on par or close to the feature set you get in the more recent version of Visual C++? In detail: As someone who has spent a lot of time programming in Windows, one of the larger stumbling blocks I've found whenever I have to code C++ in Linux is that debugging anything using commandline gdb takes me several times longer than it does in Visual Studio, and it does not seem to be getting better with practice. Some things are just easier or faster to express graphically. Specifically, I'm looking for a GUI that: Handles all the basics like stepping over & into code, watch variables and breakpoints Understands and can display the contents of complex & nested C++ data types Doesn't get confused by and preferably can intelligently step through templated code and data structures while displaying relevant information such as the parameter types Can handle threaded applications and switch between different threads to step through or view the state of Can handle attaching to an already-started process or reading a core dump, in addition to starting the program up in gdb If such a program does not exist, then I'd like to hear about experiences people have had with programs that meet at least some of the bullet points. Does anyone have any recommendations? Edit: Listing out the possibilities is great, and I'll take what I can get, but it would be even more helpful if you could include in your responses: (a) Whether or not you've actually used this GUI and if so, what positive/negative feedback you have about it. (b) If you know, which of the above-mentioned features are/aren't supported Lists are easy to come by, sites like this are great because you can get an idea of people's personal experiences with applications.

  • TDD approach for complex function

    - by jamie
    I have a method in a class for which they are a few different outcomes (based upon event responses etc). But this is a single atomic function which is to used by other applications. I have broken down the main blocks of the functionality that comprise this function into different functions and successfully taken a Test Driven Development approach to the functionality of each of these elements. These elements however aren't exposed for other applications would use. And so my question is how can/should i easily approach a TDD style solution to verifying that the single method that should be called does function correctly without a lot of duplication in testing or lots of setup required for each test? I have considered / looked at moving the blocks of functionality into a different class and use Mocking to simulate the responses of the functions used but it doesn't feel right and the individual methods need to write to variables within the main class (it felt really heath robinson). The code roughly looks like this (i have removed a lot of parameters to make things clearer along with a fair bit of irrelevant code). public void MethodToTest(string parameter) { IResponse x = null; if (function1(parameter)) { if (!function2(parameter,out x)) { function3(parameter, out x); } } // ... // more bits of code here // ... if (x != null) { x.Success(); } }

  • Removing a view from Eclipse Window -> Show views

    - by RCP
    We have an application in which some views only work when attached to certain perspectives. We want to remove those views from the Window - Show View menu so that users cannot add them to perspectives where they don't work. Any ideas on how to do this either programmatically or declaratively?

  • Best Practices For Secure APIs?

    - by Ferrett Steinmetz
    Let's say I have a website that has a lot of information on our products. I'd like some of our customers (including us!) to be able to look up our products for various methods, including: 1) Pulling data from AJAX calls that return data in cool, JavaScripty-ways 2) Creating iPhone applications that use that data; 3) Having other web applications use that data for their own end. Normally, I'd just create an API and be done with it. However, this data is in fact mildly confidential - which is to say that we don't want our competitors to be able to look up all our products every morning and then automatically set their prices to undercut us. And we also want to be able to look at who might be abusing the system, so if someone's making ten million complex calls to our API a day and bogging down our server, we can cut them off. My next logical step would be then to create a developers' key to restrict access - which would work fine for web apps, but not so much for any AJAX calls. (As I see it, they'd need to provide the key in the JavaScript, which is in plaintext and easily seen, and hence there's actually no security at all. Particularly if we'd be using our own developers' keys on our site to make these AJAX calls.) So my question: after looking around at Oauth and OpenID for some time, I'm not sure there is a solution that would handle all three of the above. Is there some sort of canonical "best practices" for developers' keys, or can Oauth and OpenID handle AJAX calls easily in some fashion I have yet to grok, or am I missing something entirely?

  • Vector Troubles in C++

    - by DistortedLojik
    I am currently working on a project that deals with a vector of objects of a People class. The program compiles and runs just fine, but when I use the debugger it dies when trying to do anything with the PersonWrangler object. I currently have 3 different classes, one for the person, a personwrangler which handles all of the people collectively, and a game class that handles the game input and output. Edit: My basic question is to understand why it is dying when it calls outputPeople. Also I would like to understand why my program works exactly as it should unless I use the debugger. The outputPeople function works the way I intended that way. Edit 2: The callstack has 3 bad calls which are: std::vector ::begin(this=0xbaadf00d) std::vector ::size(this=0xbaadf00d) PersonWrangler::outputPeople(this=0xbaadf00d) Relevant code: class Game { public: Game(); void gameLoop(); void menu(); void setStatus(bool inputStatus); bool getStatus(); PersonWrangler* hal; private: bool status; }; which calls outputPeople where it promptly dies from a baadf00d error. void Game::menu() { hal->outputPeople(); } where hal is an object of PersonWrangler type class PersonWrangler { public: PersonWrangler(int inputStartingNum); void outputPeople(); vector<Person*> peopleVector; vector<Person*>::iterator personIterator; int totalPeople; }; and the outputPeople function is defined as void PersonWrangler::outputPeople() { int totalConnections = 0; cout << " Total People:" << peopleVector.size() << endl; for (unsigned int i = 0;i < peopleVector.size();i++) { sort(peopleVector[i]->connectionsVector.begin(),peopleVector[i]->connectionsVector.end()); peopleVector[i]->connectionsVector.erase( unique (peopleVector[i]->connectionsVector.begin(),peopleVector[i]->connectionsVector.end()),peopleVector[i]->connectionsVector.end()); peopleVector[i]->outputPerson(); totalConnections+=peopleVector[i]->connectionsVector.size(); } cout << "Total connections:" << totalConnections/2 << endl; }

  • prefix routing cakephp

    - by nick martin
    Hello, Just a quick one.. I am unsure how to prevent a prefix, for example if I am in domain.com/admin/orders or domain.com/user/order which are admin_ and user_ actions and the navigation menu contains links to pages displays (controller pages action display, **) when they are clicked on they are automatically prefixed by the current prefix. How can I set in the router file to redirect wildcards prefixes (ie. /pages/)?

  • Disabling/removing the Team Foundation addin/extension in Visual Studio 2010?

    - by Lasse V. Karlsen
    I have an older laptop that I won't get around to replacing for another month or two. It has 1GB of memory so I'm trying to squeeze applications as much as possible. In Visual Studio 2010, it has apparently loaded some extensions related to Team Foundation Server, since I have menu items and dialog choices for it. Questions: Would I save a noticable amount of memory (even a couple of MB would be good) if I managed to disable this? How do I disable it?

  • Possible to alert server to iphone settings change?

    - by DougW
    I'm working on giving our users context-specific PUSH notification settings, similar to what Facebook has in their settings menu. As far as I can tell though, there's no way to actually notify our server of these changes until the user actually launches the app. Is this correct? Is there any mechanism provided for immediately alerting our servers to a settings change?
