• Software buttons in the android 4.2 emulator not showing up (tablet)

  - by The_Unknown

  I'm getting crazy right now. I just installed the latest android adt bundle from http://developer.android.com/sdk/index.html. It's version v21.0.0. Now I wanted to test my tablet app (designed for 10.1" xlarge mdpi) in the emulator, but I cannot get any software buttons for home/back/... Here's my device configuration. This config is afterwards assigned to the avd. http://i.stack.imgur.com/Q7xvP.png Hardware-buttons don't work as well (you cannot set hardware buttons in a tablet-like emulator). The target api is level 15 (android 4.0.3). I searched stackoverflow, but didn't find any help concerning the latest version of android. Since time's running away a little, any quick help would be great! Thanks in advance. Bye The_Unknown

• IE display problem

  - by bah

  Hi, I have a page, and I just added pagination to it, but there's a prob in IE 7 & 8. When I add pagination code echo "<div class='pagination'>"; echo $pagination->GetPageLinks(); echo "</div>"; it breaks somehow layout in IE, I have looked all over it and I couldn't find what's wrong there. oh, and its css div.pagination { text-align : center; } div.pagination a, div.pagination span { padding : 5px; display : inline-block; } page url - adelija.puslapiai.lt, it's on index page, if you could take a look, that'd be great.

• Drupal, template.php where do the $form names come from ?

  - by Patrick

  hi, I want to customize my Drupal back-end forms. I'm using template.php file.. i.e. $form['menu']['#collapsed'] = true; $form['author']['#collapsed'] = true; $form['buttons']['#weight'] = 100; But I was wondering from where the section names (menu, author, buttons), come from. (They are not id or classes in html code, so I guess there is an index with all names stored somewhere. Where can I get the complete list of section names ? Furthermore, I've added a taxonomy-super-select-checkboxes section by installing the module. How can I refer to this section, to make the field not collapsed. thanks

• How do I iterate over a tuple

  - by Caligo

  How can I iterate over a tuple starting from, say, index 1 to 2? The following doesn't work. using boost::fusion::cons; typedef cons<A, cons<B, cons<C, cons<D> > > > MyTuple; MyTuple tuple_; template <class T> struct DoSomething{ DoSomething(T& t) : t_(&t){ } template <class U> void operator()(U u){ boost::fusion::at<mpl::int_<u> >(*t_); } T* t_; }; boost::mpl::for_each< boost::mpl::range_c<int, 1, 3> >( DoSomething<MyTuple>(tuple_) );

• background semitransparent div

  - by plasticrabbit

  I want to show some dialog (absolute positioned div), and I want to show it above semitransparent 100% div, so everything on background will be dimmed. I have managed it by <div class='transpBox'></div> .transparentBox { position: absolute; top: 0px; left: 0px; width: 100%; height: 100%; background-color: #white; opacity: 0.9; z-index: 499; } This is all right, but when dialog height is more than browser height and you scroll down, you see that transparent div is not in full screen. What is proper way to make such thing?

• Magento - createBlock() in controller, can I access this in layout.xml?

  - by pspahn

  I have an index controller with a view action that does the following: echo $this->getLayout() ->createBlock('core/template','builder') ->setTemplate('pages/builder/view.phtml') ->setHeaderText($extra->getHeaderText()) ->setFooterText($extra->getFooterText()) ->setProducts($collection) ->toHtml(); Based on this, I am trying to perform layout updates in builder.xml (which is being set in the module's config.xml). However, I am not sure if you can target blocks instantiated in this manner. Based on the above block creation, am I able to perform the following: <layout version="0.1.0"> <builder_index_view> <!-- shouldn't this reference the createBlock() name argument? --> <reference name="builder"> <block type="page/html_header" name="builder.header" as="builder.header" template="pages/builder/header.phtml"/> </reference> </builder_index_view> </layout>

• compromised site

  - by pinniger

  So, I have a web site that has been compromised twice in two weeks. every index.php and .js file gets a script injecting into the source code of the file. The problem is that I have no idea how they're doing it. I've seen this done via sql injection before, but I don't know how they are actually writing to the file. I've dug through the Apache logs but didn't find anything interesting. The site is built using the cakephp framework on a godaddy shared server. Anybody know what secturity settings or log files to check to see how they are doing this?

• Can a programming language without arrays be turing-complete?

  - by Ring

  My question is simple: There are no arrays possible. That means you can address variables only "statically" by directly using their unique name. (This already throws out the default array syntax variable[ index ] and variable variables) "Emulated arrays" are counted as arrays and excluded too. Examples: You could basically simulate arrays using strings (quite easily actually) or use variable variables as in PHP. Can such a language be turing-complete? Brainf*ck for example has arrays, in fact it is one big array, isn't it?

• Looking for an array (vs linked list) hashtable implementation in C

  - by kingusiu

  hi, I'm looking for a hashtable implementation in C that stores its objects in (twodimensional) arrays rather than linked lists. i.e. if a collision happens, the object that is causing the collision will be stored in the next free row index rather than pushed to the head and first element of a linked list. plus, the objects themselves must be copied to the hashtable, rather than referenced by pointers. (the objects do not live for the whole lifetime of the program but the table does). I know that such an implementation might have serious efficiency drawbacks and is not the "standard way of hashing" but as I work on a very special system-architecture i need those characteristics. thanks

• Most efficient way to maintain a 'set' in SQL Server?

  - by SEVEN YEAR LIBERAL ARTS DEGREE

  I have ~2 million rows or so of data, each row with an artificial PK, and two Id fields (so: PK, ID1, ID2). I have a unique constraint (and index) on ID1+ID2. I get two sorts of updates, both with a distinct ID1 per update. 100-1000 rows of all-new data (ID1 is new) 100-1000 rows of largely, but not necessarily completely overlapping data (ID1 already exists, maybe new ID1+ID2 pairs) What's the most efficient way to maintain this 'set'? Here are the options as I see them: Delete all the rows with ID1, insert all the new rows (yikes) Query all the existing rows from the set of new data ID1+ID2, only insert the new rows Insert all the new rows, ignore inserts that trigger unique constraint violations Any thoughts?

• How to save an order (permutation) in an sql db

  - by Bendlas

  I have a tree structure in an sql table like so: CREATE TABLE containers ( container_id serial NOT NULL PRIMARY KEY, parent integer REFERENCES containers (container_id)) Now i want to define an ordering between nodes with the same parent. I Have thought of adding a node_index column, to ORDER BY, but that seem suboptimal, since that involves modifying the index of a lot of nodes when modifying the stucture. That could include adding, removing, reordering or moving nodes from some subtree to another. Is there a sql datatype for an ordered sequence, or an efficient way to emulate one? Doesn't need to be fully standard sql, I just need a solution for mssql and hopefully postgresql EDIT To make it clear, the ordering is arbitrary. Actually, the user will be able to drag'n'drop tree nodes in the GUI

• Comparing structs in C++

  - by kamziro

  So in C++ There's a lot of times where you need to make an "index" class. For example: class GameID{ public: string name; int regionid; int gameid; bool operator<(const GameID& rhs) const; } Now, if we were to represent GameID as pair , the operator comparison just comes with it. Is there any other way to get that automatic operator comparison without having to use std::pair< ?

• Can you use POST to run a query in Solr (/select)

  - by RyanFetz

  I have queries that I am running against out solr index that sometimes have very long query parameters, I get errors when i run these queries, which i assume are do to the limit of a GET query parameters. Here is the method I use to query (JSON), this is to show I am using the Http Extensions (the client i use is a thin wrapper for HttpClient) not an end to end solution. 90% of the queries run fine, it is just when the params are large i get the 500 error from solr. I have read somewhere you can use POSt's when doing the select command but have not found examples of how to do it. Any help would be fantastic! public string GetJson(HttpQueryString qs) { using (var client = new DAC.US.Web.XmlHttpServiceClient(this.Uri)) { client.Client.DefaultHeaders.Authorization = new Microsoft.Http.Headers.Credential("Basic", DAC.US.Encryption.Hash.WebServiceCredintials); qs.Add("wt", "json"); if (!String.IsNullOrEmpty(this.Version)) qs.Add("version", this.Version); using (var response = client.Get(new Uri(@"select/", UriKind.Relative), qs)) { return response.Content.ReadAsString(); } } }

• CakePHP delete() function is not working

  - by Logic Artist

  Hello, Im just cracking open cakePHP (v1.3.2). I set it up on my local wamp server, seems to work fine except the delete() function doesn't work. I'm following their blog tutorial exactly, its as simple as it can be so I don't understand why its not working. Heres the function in my PostsController class: function delete($id = NULL) { $this->Post->delete($id); $this->Session->setFlash('The post with id: '.$id.' has been deleted.'); $this->redirect(array('action'=>'index')); } The "Delete" link's url looks like http://localhost/posts/delete/id:1 (where the id number matches the particular post, obviously). It redirects and sets the flash message, however there is no number where $id should be in the message, and the post isn't deleted. It seems the proper id is passed through the url, but I don't think it is getting into the function. I dont get it. Any ideas???

  http://developer.apple.com/iphone/library/navigation/index.html?section=Resource+Types&topic=Getting+Started Can I have some code ? This one appears to have a scroller to the right side of the screen and the footer gets sticky to the bottom. But i guess this is a bit different to most of the Sticky footers you're talking about in other threads. I'm going to need some good code to use, as I can't think alike other people and I learn from used code. Iwill be happy to help other people too ...

• Using cachedwithin attibute inside cfquery

  - by Jason

  When you use the cachedwithin attribute in a cfquery how does it store the query in memory. Does it store it by only the name you assign to the query? For example, if on my index page I cache a query for an hour and name it getPeople will a query with the same name on a different page (or the same page for that matter) use the cached results or does it use some better logic to decide if it is the same query? Also, if there is a variable in your query does the cache take into account the value of the variable?

• How do I obtain an HtmlHelper<TModel> instance for a model in ASP.NET MVC?

  - by DanM

  Let's say I have an Index view. The model I pass in is actually a collection of models, so the Html property is of type HtmlHelper<List<MyModel>>. If I want to call extension methods (e.g., Display() or DisplayFor() on the individual items in the list, however, I think I need to obtain an HtmlHelper<MyModel>. But how? I tried using the HtmlHelper<TModel> constructor, which looks like this: HtmlHelper<TModel>(ViewContext, IViewDataContainer) But I'm not having any luck with that. I don't know how to obtain the IViewDataContainer for the item, and the documentation on these things is very sparse. A lot of magic apparently happens when I do... return View(List<MyModel>); ...in my controller. How do I recreate that magic on individual items in a list/collection?

• Measuring execution time of a call to system() in C++

  - by jm1234567890

  I have found some code on measuring execution time here http://www.dreamincode.net/forums/index.php?showtopic=24685 However, it does not seem to work for calls to system(). I imagine this is because the execution jumps out of the current process. clock_t begin=clock(); system(something); clock_t end=clock(); cout<<"Execution time: "<<diffclock(end,begin)<<" s."<<endl; Then double diffclock(clock_t clock1,clock_t clock2) { double diffticks=clock1-clock2; double diffms=(diffticks)/(CLOCKS_PER_SEC); return diffms; } However this always returns 0 seconds... Is there another method that will work? Also, this is in Linux. Thanks!

• MySQL pivot tables - covert rows to columns

  - by user2723490

  This is the structure of my table: Then I run a query SELECT `date`,`index_name`,`results` FROM `mst_ind` WHERE `index_name` IN ('MSCI EAFE Mid NR USD', 'Alerian MLP PR USD') AND `time_period`='M1' and get a table like How can I convert "index_name" rows to columns like: date | MSCI EAFE Mid NR USD | Alerian MLP PR USD etc In other words I need each column to represent an index and rows to represent date-result. I understand that MySQL doesn't have pivot table functions. What is the easiest way of doing this? I've tried this code, but it generates an error: SELECT `date`, MAX(IF(index_name = 'Alerian MLP PR USD' AND `time_period`='M1', results, NULL)) AS res1, MAX(IF(index_name = 'MSCI EAFE Mid NR USD' AND `time_period`='M1', results, NULL)) AS res2 FROM `mst_ind` GROUP BY `date I need to make the conversion on the query level - not PHP. Please suggest a nice and elegant solution. Thanks!

• jQuery.get() - Practical uses?

  - by RedWolves

  I am trying to understand why you would use jQuery.get() and jQuery.get(index). The docs say it is to convert the jQuery selection to the raw DOM object instead of working with the selection as a jQuery object and the methods available to it. So a quick example: $("div").get(0).innerHTML; is the same as: $("div").html(); Obviously this is a bad example but I am struggling to figure when you would use .get(). Can you help me understand when I would use this method in my code?

• which one consume less resources? opening text file or make an sql query,both a thousand times ?

  - by imin

  hi I've a php website which displays recipes www.trymasak.my, to be exact. The recipes being displayed at the index page is updated about once a day. To get the latest recipes, I just use a mysql query which is something like "select recipe_name, page_views, image from table order by last_updated". So if I got 10000 visitors a day, obviously the query would be made 10000 times a day. A friend told me a better way (in terms of reducing server load) is when I update the recipes, I just put in the latest recipe details (names,images etc) into a text file, and make my page instead of querying a same query for 10,000 times, just get the data from the text file. Is his suggestion really better? If yes, which is the best php command should I use to open, read and close the text file? thanks

• how to access child instances in a vector in c++

  - by tsubasa

  I have a parent class and child class (inherited from parent). In the child class, I have a member function named function_blah(); I used vector<parent*> A to store 5 parent instances, 3 child instances. So the total number of elements in the vector is 8. I can easily access to member functions of element A[0] to A[4], which are parent instances. But whenever I try to have access to member functions of element A[5] to A[7], the compiler complains that class parent has no member named 'function_blah' The way I access to elements is using index. e.x A[i] with i = 0..7. Is it correct? if not, how?

• Allow users to enter a variable length list of items in asp.net form

  - by EJB

  I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list. I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order). What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation?
