  • Is there a good date/time API available for Scala?

    - by Erik Engbrecht
    I'm looking for something akin to JodaTime or JSR 310 for Scala that leverages nice Scala features such as operator overloading and doesn't rely on implicit conversions (I have an irrational fear of implicit conversions). I'm aware of http://github.com/jorgeortiz85/scala-time, but it just pimps JodaTime with implicits.

  • CompareValidator issue on Firefox

    - by costin
    Hi, I need to validate a date in a web forms application. For this I use a CompareValidator with Operator="DataTypeCheck" Type="Date" The problem is that this Validator doesn't work properly on Firefox with 2 digit years. ( javascript error: m[2] is undefined) With a 4 digits year it's working properly. This problem is described also here: https://connect.microsoft.com/VisualStudio/feedback/details/355573/comparevalidator-client-side-bug-two-digit-year-in-mozilla-based-browsers-throws-js-exception Does anyone know a nice workaround for this? Thanks

  • Bad_alloc exception when using new for a struct c++

    - by bsg
    Hi, I am writing a query processor which allocates large amounts of memory and tries to find matching documents. Whenever I find a match, I create a structure to hold two variables describing the document and add it to a priority queue. Since there is no way of knowing how many times I will do this, I tried creating my structs dynamically using new. When I pop a struct off the priority queue, the queue (STL priority queue implementation) is supposed to call the object's destructor. My struct code has no destructor, so I assume a default destructor is called in that case. However, the very first time that I try to create a DOC struct, I get the following error: Unhandled exception at 0x7c812afb in QueryProcessor.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x0012f5dc.. I don't understand what's happening - have I used up so much memory that the heap is full? It doesn't seem likely. And it's not as if I've even used that pointer before. So: first of all, what am I doing that's causing the error, and secondly, will the following code work more than once? Do I need to have a separate pointer for each struct created, or can I re-use the same temporary pointer and assume that the queue will keep a pointer to each struct? Here is my code: struct DOC{ int docid; double rank; public: DOC() { docid = 0; rank = 0.0; } DOC(int num, double ranking) { docid = num; rank = ranking; } bool operator>( const DOC & d ) const { return rank > d.rank; } bool operator<( const DOC & d ) const { return rank < d.rank; } }; //a lot of processing goes on here; when a matching document is found, I do this: rank = calculateRanking(table, num); //if the heap is not full, create a DOC struct with the docid and rank and add it to the heap if(q.size() < 20) { doc = new DOC(num, rank); q.push(*doc); doc = NULL; } //if the heap is full, but the new rank is greater than the //smallest element in the min heap, remove the current smallest element //and add the new one to the heap else if(rank > q.top().rank) { q.pop(); cout << "pushing doc on to queue" << endl; doc = new DOC(num, rank); q.push(*doc); } Thank you very much, bsg.

  • Naming member functions/methods with a single underscore, good style or bad?

    - by Extrakun
    In some languages where you cannot override the () operator, I have seen methods with a single underscore, usually for 'helper' classes. Something likes this: class D10 { public function _() { return rand(1,10); } } Is it better to have the function called Roll()? Is a underscore fine? After all, there is only one function, and it removes the need to look up the name of the class. Any thoughts?

  • Searching via Tags in SharePoint 2010

    - by Ben
    Is it possible to search on Tags within SharePoint 2010? I know you can refine your search based on Tag (Search for a keyword, then filter by Tags) and you can use the "Tag Cloud", but that doesnt let you search by more then one Tag. How would I for instance, search for some documents that I have tagged as "Technical" and "Internal", and return all items tagged with both of those tags?

  • SEO difference between dash and hypen

    - by FFish
    I understand with dashes once can search for keywords in different order. What if my keyword has a space in it like real estate or New York Should I use underscores in this case? If I do a Google search for New_York Google hints me: Did you mean: New York There is clearly a difference. Even capitals seems to make a difference, looking at the search results..

  • using CSS to center FLOATED input elements wrapped in a DIV

    - by Tim
    There's no shortage of questions and answers about centering but I've not been able to get it to work given my specific circumstances, which involve floating. I want to center a container DIV that contains three floated input elements (split-button, text, checkbox), so that when my page is resized wider, they go from this: ||.....[ ][v] [ ] [ ] label .....|| to this ||......................[ ][v] [ ] [ ] label.......................|| They float fine, but when the page is made wider, they stay to the left: ||.....[ ][v] [ ] [ ] label .......................................|| If I remove the float so that the input elements are stacked rather than side-by-side: [ ][v] [ ] [ ] label then they DO center correctly when the page is resized. SO it is the float being applied to the elements of the DIV#hbox inside the container that is messing up the centering. Is what I want to do impossible because of the way float is designed to work? Here is my DOCTYPE, and the markup does validate at w3c: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> Here is my markup: <div id="term1-container"> <div class="hbox"> <div> <button id="operator1" class="operator-split-button">equals</button> <button id="operator1drop">show all operators</button> </div> <div><input type="text" id="term1"></input></div> <div><input type="checkbox" id="meta2"></input><label for="meta2" class="tinylabel">meta</label></div> </div> </div> And here's the (not-working) CSS: #term1-container {text-align: center} .hbox {margin: 0 auto;} .hbox div {float:left; } I have also tried applying display: inline-block to the floated button, text-input, and checkbox; and even though I think it applies only to text, I've also tried applying white-space: nowrap to the #term1-container DIV, based on posts I've seen here on SO. And just to be a little more complete, here's the jQuery that creates the split-button: $(".operator-split-button").button().click( function() { alert( "foo" ); }).next().button( { text: false, icons: { primary: "ui-icon-triangle-1-s" } }).click( function(){positionOperatorsMenu();} ) })

  • How to search a MySQL database for a specific string

    - by Nadia
    I am trying to set up a search feature on my site that will only return exact matches to keyword entered by the user. So if the user searches "dog" I don't want an article titled "Doggy Style" to appear in the search results (just an example I don't really have an article by that name). This of course does exactly that: SELECT * FROM articles WHERE article_title LIKE '%$searchQuery%' $searchQuery here is a PHP variable taken from the user's input form. So is there any way to return only exact matches?
