  • How to Vertically Center Images on a Line?

    - by jeremy
    What's the best way to center icons on a line when the images are smaller than the line height? For example (styles inline for easier reading): <div style="line-height: 20px"> <img style="width: 12px; height: 12px;"/> Blah blah blah </div> Here's a jsFiddle example. This example also shows why vertical-align: middle does not work. I want the img to be centered against the text of the div. That is, even if the text wrapped to multiple lines, the image would be centered against a single line. Ideally, the solution would not involve setting margings/paddings on the image and would work even if I didn't know the line-height. Things I've read: How do I vertically align text next to an image with CSS? (deals with case where image is larger, doesn't seem to apply here) Understanding vertical-align

  • Undefined / Uninitialized default values in a class

    - by Jir
    Let's suppose you have this class: class A { public: A () {} A (double val) : m_val(val) {} ~A () {} private: double m_val; }; Once I create an instance of A, how can I check if m_val has been initialized/defined? Put it in other words, is there a way to know if m_val has been initialized/defined or not? Something along the lines of the defined operator in Python, I suppose. (But correct me if I'm wrong.) I thought of modifying the class and the c-tors the following way: class A { public: A () : defined(false) {} A (double val) : m_val(val), defined(true) {} ~A () {} private: double m_val; bool defined; }; How do you rate this solution? Any suggestion? TIA, Chris

  • Delete database. Entity Framework

    - by Idotz
    I have a very annoying issue and I would love a solution. The problem: I followed the MDSN tutorial- http://www.asp.net/mvc/tutorials/mvc-4/getting-started-with-aspnet-mvc4/adding-a-model Then I tried this guide according to my needs and I set up a database GAMES.MDF.   Then, I deleted the database and set it up again, is supposedly work (I can write and read data), but There is no such database in the APP_DATA folder. Like it keeps it somewhere in my PC and reuse it.   I even tried a new project and it did not work, works but not in the library, and it even uses the data I created before. I even deleted the DB from SQL Server Management Studio 2008. Does anyone know what the hell? How do I delete it permanently, not to remain any trace of him?   Thank you.  Ido

  • Visual Studio 2010 debug minidump

    - by Snake
    Hi all, Consider the following code (written with Visual Studio 2010 and .NET 4.0) using System; namespace DumpTester { class Program { static void Main(string[] args) { int test = new Random().Next(); Console.WriteLine(test + new Random().Next()); Test(); } private static void Test() { throw new Exception(); } } } When running outside of Visual Studio you get this nice window of Microsoft Windows 7 that it is looking for a solution. Obviously, since this is my app, there is none. At that point I create a full dump file of my application with for example Process Explorer. I then open that dmp file from its location and try to debug. But whatever I try, it can't find the location of the source symbols. I tried putting the pdb next to the dump but it just doesn't find it. What am I doing wrong?

    I have two projects in my solution 1- asp.net web project. 2- wcf serivce project. 3- other common projects between two listed above Currently on the local dev machine I have to run two visual studio instance to run both projects in debug mode.

Have already considred this option. thanks for sharing your thoughts in advance.

  • ConfigurationSection with multiple projects

    - by shivesh
    In my asp.net solution i have a couple of class library-projects that act as modules of the site. In main project I have SiteConfigurationSection class that derives from ConfigurationSection. I want all projects to be able to access and use this SiteConfigurationSection. But class library projects can't access it because they obviously don't have a reference to the website itself. Should create a special library-project for SiteConfigurationSection of maybe it's better to create a mini SiteConfigurationSection class in every project and encapsulate only the needed values?

  • Making dynamic images have static filenames

    - by michaeltk
    My website currently has various links to a php script that generates the images dynamically. For example, the link may say "img source="/dynamic_images.php?type=pie-chart&color=red" Obviously, this is not great for SEO. I'd like to somehow make the filenames of these links appear to be static, and use a solution (like Mod-Rewrite) to ensure that the images can still be dynamically created. I suppose I could have something like "img src="average-profits-in-scuba-diving-industry.png?type=pie-chart&color=red" (and use Mod-Rewrite to take care of changing the filename prefix to dynamic_images.php), but I'm afraid that the search engines would shy away from the querystring on the end of the image filename. Any solutions? Thanks in advance.

  • [app-engine-java-groovy] One-to-Many relationship. Select objects from datastore.

    - by Olexandr
    Hi. I've omitted some code(package declarations, imports, other fields) for shortness. I have here simple One-to-Many relation. It worked fine till this moment. @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true") class Restaurant implements Serializable { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Key id @Persistent(mappedBy = "restaurant") List<RestaurantAddress> addresses = new ArrayList<RestaurantAddress>() } //-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true") class RestaurantAddress implements Serializable { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Key id @Persistent Restaurant restaurant } Now i need to get(select) all the Restaurants from DB: def getRestaurantsToExport(final String dst, final int count) { String field = restaurantExportFields[dst] return transactionExecute() { PersistenceManager pm -> Query q = pm.newQuery(Restaurant.class) q.filter = "$field == null" q.setRange(0, count) return q.execute() } } But there are on problem - query gives me 12 restaurants(as in DB) but every Restaurant has 0 Address but in Datastore every Restaurant has minimum 2 addresses. Have anyone the same problem or knows the solution ?

  • Strange margin-behaviour with Sifr spans in link (screens)

    - by knalstaaf
    I'm making a menu and it's supposed to look like picture nr 1 on this link. However, at this moment, it looks like picture nr 2. There's no logic in this behaviour, since all three elements have the same css-attributes. Moreover, let's change the word "Reiki" to "Psychotherapie" and see what happens... (picture nr 3) For some reason the word "Reiki" ignores certain attributes. This is not a problem when Sifr is turned off. I guess I'll need some extra CSS to solve this (messing with paddings, heights or margins on that specific element doesn't give any result. It just won't budge). Unless someone knows a more elegant solution?

  • Touch Screen Product Catalog for Retail Store

    - by Patrick
    I am a UI/UX designer and I would like to create kiosk type of app that would be a product catalog (help/suggestor) for customers in a retail store using a touch screen monitor (and computer). Something as simple as this: http://www.youtube.com/watch?v=aoH0u6YTTK4 This is what I would like it to do: 1st Screen (Main Menu): Pick a type of category (For example: Dog, Cat, Small Animal) 2nd Screen pick a sub-category of a main category (For example: Puppy, Adult, Senior - DOG) 3rd Screen pick a sub-category of previous sub-category (For example: Food, Healthy, Toys) Then it will display a list of all products with a picture, small description, and price. Thats it. So the point of the kiosk is to help customers find certain products that match their pet criteria. (Dog Puppy Healthy Dog Food) I am wondering what is the best solution: RIA (Flex/Air or Silveright) or flash/action script. I am not sure what is the best technology to use for the following benefits: user-experience (smoothness of touch screen actions) and fast development.

  • how to make this "action-packed, random data" being echoed in a terminal?

    - by RiMMER
    OK, this isn't really a question to achieve anything practical, but still it is a serious question and I hope it will be taken seriously and mods won't punish me for this :) I'm sure majority of you have seen some good action movie, where CIA or FBI or hackers or any other "pc nerds" are "retrieving some information" and when they actually show their screens/monitors/desktops, there is a lot of random data being displayed and it's just so thrilling :D So, we're shooting a movie and I need to reconstruct such a scene. My OS is ubuntu 10.10. I think i've read somewhere on the internet once that shell can actually be recorded and then played back, but I'm not sure how it worked. If there's anyone who could come up with a solution, it would be so cool! Let's make this fun, shall we?

  • Is MS Access still the most efficient RAD tool for small-scale custom apps?

    - by FastAl
    Of the many other development tools I've used, nothing holds a candle to the 'Functionality to Development Effort' ratio of MS Access. The reason I am asking is that I have been out of the language selection process for a few years, working on a large .Net system, and am only anecdotally familiar with the latest development tools outside the .Net world. I'm well aware of the limitations of Access, but for a limited concurrency (usually only 1 user at a time), small business, custom app, has anybody found a comparable end-to-end solution or combination that comes close? It doesn't have to be free, open source, or even Windows based. It just has to allow the same speed of development and maintenance, and maybe even provide some additional amenities like seamless autointegration with a server-based DB Engine (like Access does with its own 'Jet' dbms), better web support, and a file format more compatible with source control. I don't want to miss out on anything. Please share your development experience with your suggestions. Thanks.

  • What is wrong with my @synchronized block?

    - by hyn
    I have 2 threads in my application, a game update thread and render/IO/main thread. My update thread updates the game state, and the render thread renders the scene based on the updated values of the game state models and a few other variables stored inside an object (gameEngine). The render thread gets executed while the game thread is still updating, which is a problem, so it appeared to me the solution is to use @synchronized like this: @synchronized(gameEngine) { [gameEngine update]; nextUpdate = now + GAME_UPDATE_INTERVAL; gameEngine.lastGameUpdateInterval = now - lastUpdate; gameEngine.lastGameUpdateTime = now; lastUpdate = now; } But the render thread still accesses the gameEngine object between -update and the last 3 lines of the block. Why is this?

  • mvc - how to avoid log out when refresh a page

    - by user235973457
    I have built the MVC application with WCF service. The major problem I have experienced with refreshing page. I have created a login page with session (username and password). But when you refresh the home page by pressing F5, it would automatically log out. That is my problem. I need to stay the home page after refresh. I have been googling around to find a solution but it seems not helpful. Any idea? Your advise or code example much appreciated.

  • Is it so bad to have heaps of elements in your DOM?

    - by alex
    I am making a real estate non interactive display for their shop window. I have kicked jCarousel into doing what I want: Add panels per AJAX Towards the end of the current set, go and AJAX some new panels and insert them This works fine, but it appears calling jQuery's remove() on the prior elements cause an ugly bump. I'm not sure if calling hide() will free up any resources, as the element will still exist (and the element will be off screen anyway). I've seen this, and tried carousel.reset() from within a callback. It just clears out all the elements. This will be running on Google Chrome on Windows XP, and will solely by displaying on LCD televisions. I am wondering, if I can't find a reasonable solution to remove the extra DOM elements, will it bring my application to a crawl, or will Chrome do some clever garbage collecting? Or, how would you solve this problem? Thanks

  • How to find the most recent associations created between two objects with Rails?

    - by Kevin
    Hi, I have a user model, a movie model and this association in user.rb (I use has_many :through because there are other associations between these two models): has_many :has_seens has_many :movies_seen, :through = :has_seens, :source = :movie I'm trying to get an array of the ten most recent has_seens associations created. For now, the only solution I found is to crawl through all the users, creating an array with every user.has_seens found, then sort the array by has_seen.created_at and only keep the last 10 items… Seems like a heavy operation. Is there a better way? Kevin

  • Adding a method to a function object at runtime

    - by Carson Myers
    I read a question earlier asking if there was a times method in Python, that would allow a function to be called n times in a row. Everyone suggested for _ in range(n): foo() but I wanted to try and code a different solution using a function decorator. Here's what I have: def times(self, n, *args, **kwargs): for _ in range(n): self.__call__(*args, **kwargs) import new def repeatable(func): func.times = new.instancemethod(times, func, func.__class__) @repeatable def threeArgs(one, two, three): print one, two, three threeArgs.times(7, "one", two="rawr", three="foo") When I run the program, I get the following exception: Traceback (most recent call last): File "", line 244, in run_nodebug File "C:\py\repeatable.py", line 24, in threeArgs.times(7, "one", two="rawr", three="foo") AttributeError: 'NoneType' object has no attribute 'times' So I suppose the decorator didn't work? How can I fix this?

  • How to solve this Java type safety warning? (Struts2)

    - by Nicolas Raoul
    Map session = ActionContext.getContext().getSession(); session.put("user", user); This code generates a warning: Type safety: The method put(Object, Object) belongs to the raw type Map. References to generic type Map should be parameterized. Map<String, Serializable> session = (Map<String, Serializable>)ActionContext.getContext().getSession(); session.put("user", user); This code generates a warning: Type safety: Unchecked cast from Map to Map. The getSession method belongs to Struts2 so I can't modify it. I would like to avoid using @SuppressWarnings because other warnings can be useful. I guess all Struts2 users in the world faced the same problem... is there an elegant solution?

  • how do I integrate the aspnet_users table that comes with asp.net membership into my existing databa

    - by ooo
    i have a database that already has a users table COLUMNS: userID - int loginName - string First - string Last - string i just installed the asp.net membership table. Right now all of my tables are joined into my users table foreign keyed into the "userId" field How do i integrate asp.net_users table into my schema? here are the ideas i thought of: Add a membership_id field to my users table and on new inserts, include that new field in my users table. This seems like the cleanest way as i dont need to break any existing relationships. break all existing relationship and move all of the fields in my user table into the asp.net_users table. This seems like a pain but ultimately will lead to the most simple, normalized solution any thoughts?
