  • LINQ group one type of item

    - by Nelson
    I have a List that has various derived classes. I may have something like this: List<BaseClass> list = new List<BaseClass>() { new Class1(), new Class2(1), new Class3(), new Class2(2), new Class4() }; I am trying to use LINQ to semi-sort the list so that the natural order is maintained EXCEPT for Class2. All Class2 instances should be grouped together at the place that the first Class2 occurs. Here is what the output should be like: List<BaseClass> list = new List<BaseClass>() { new Class1(), new Class2(1), new Class2(2), new Class3(), new Class4() }; I can't for the life of me figure out how to do this...

  • What type of websites does memcached speed up

    - by Saif Bechan
    I have read this article about 400% boost of your website. This is done by a combination of nginx and memcached. The how-to part of this website is quite good, but i mis the part where it says to what types of websites this applies. I know nginx is a http engine, I need no explanation for that. I thought memcached had something to do with caching database result. However i don't understand what this has to do with the http request, can someone please explain that to me. Another question I have is for what types of websites is this used. I have a website where the important part of the website consist of data that changes often. Often being minutes. Will this method still apply to me, or should I just stick with the basic boring setup of apache and nothing else.

  • How to implement image map type interface for a game board in Java 6

    - by Billy
    My group project at school is to implement a style of monopoly in which students can buy courses and land on various squares and move around the board. This is not a regular square board so we were wondering if anyone had any ideas on how we would implement an image map or something like it to create many clickable regions not in a perfect square. I have attached the image of the game board. Just a way to start is needed, not lots of code or anything as we all know java pretty well. If anyone has any ideas that would be great. Image of board is here. http://imgur.com/fH5WC.png

  • boolean type for while loop in bash?

    - by user151841
    I have a cron script on a shared web host that occasionally gets killed. I'd like to make a loop in bash that tries again if it gets killed, because most of the time it will make it. I'm having trouble with the syntax for storing a boolean value :P #!/bin/bash VAR=0; while [ $VAR ]; do if nice -19 mysqldump -uuser -ppassword -h database.hostname.com --skip-opt --all --complete-insert --add-drop-table database_name > ~/file/system/path/filename.sql; then VAR=1; fi done So the script recovers from a killed process okay, but once it's run properly, the new VAR value doesn't kill the while loop. What am I doing wrong?

  • Declaring a prototype of type "struct" - C

    - by Jamie Keeling
    I've been racking my brains on this for a while, I'm simply trying to create a method that returns a struct as I wish to return two int's. My prototype for the method is as follows: typedef struct RollDice(); Also the method itself: typedef struct RollDice() { diceData diceRoll; diceRoll.dice1 = 0; diceRoll.dice2 = 0; return diceRoll; } The compiler shows the error: "Syntax error: ')'" for both the prototype and actual method. The struct itself: typedef struct { int dice1; int dice2; }diceData; Is it obvious where I'm going wrong? I've tried everything I can think of. Thanks

  • handle json request in PHP

    - by wo_shi_ni_ba_ba
    When making an ajax call, when contentType is set to application/json instead of the default x-www-form-urlencoded, server side (in PHP) can't get the post parameters. in the following working example, if I set the contentType to "application/json" in the ajax request, PHP $_POST would be empty. why does this happen? How can I handle a request where contentType is application/json properly in PHP? $.ajax({ cache: false, type: "POST", url: "xxx.php", //contentType: "application/json", processData: true, data: {my_params:123}, success: function(res){ }, complete: function(XMLHttpRequest, text_status) { } });

  • Type mismatch: cannot convert from ArrayList<Data> to MyCollection

    - by Tommy
    I've read similar questions here but I'm still a little confused. MyCollection extends ArrayList<MyClass> MyClass implements Data yet this gives me the "cannot convert from ArrayList to MyCollection" MyCollection mycollection = somehandler.getCollection(); where getCollection looks like this public ArrayList<Data> getCollection() So my assumptions are obviously wrong. How can I make this work like I would like it to

  • jquery calculation sum two different type of item

    - by st4n
    I'm writing a script like the example shown in the demo where All of the "Total" values (Including the "Grand Total") are Automatically Calculated using the calc () method. at this link: But I have some fields in which to apply the equation qty * price, and others where I want to do other operations .. you can tell me how? thank you very much i try with this, but it is a very stupid code .. and the grandTotal .. not sum the two different fields: function recalc() { $("[id^=total_item]").calc("qty * price", { qty: $("input[name^=qty_item_]"), price: $("[id^=price_item_]") }, function (s){ // return the number as a dollar amount return "$" + s.toFixed(2); }, function ($this){ // sum the total of the $("[id^=total_item]") selector var sum = $this.sum(); $("#grandTotal").text( // round the results to 2 digits "$" + sum.toFixed(2) ); }); $("[id^=total_otheritem]").calc("qty1 / price1", { qty1: $("input[name^=qty_other_]"), price1: $("[id^=price_other_]") }, function (s){ // return the number as a dollar amount return "$" + s.toFixed(2); }, function ($this){ var sum = $this.sum(); $("#grandTotal").text( // round the results to 2 digits "$" + sum.toFixed(2) ); }); }

  • How to specify multiple conditions and the type of condition using Zend_Db_Table

    - by Mario
    I have a function in my model that I need to use multiple conditions when querying. Additionally I would like to also have partial matches. I currently have: public function searchClient($search_term) { $rows = $this->fetchAll( $this->select() ->where('first_name = ?', $search_term) ); return $rows->toArray(); } Which is the equivalent of "SELECT * FROM clients WHERE first_name = 'foobar';" I would like to have a function that is the equivalent of "SELECT * FROM clients WHERE first_name LIKE '%foobar%' OR last_name LIKE '%foobar%' OR home_phone LIKE '%foobar%';" How would I create such a query within Zend_Db_Table?

  • jQuery: Moving window (or FIFO) type DIV?

    - by Legend
    I have been trying to get this effect for a couple of hours now and I must admit I am failing at it. I am trying to construct a DIV that accepts a particular number of items (say 5), when the 6th item is added, the first item that was aded should be removed (first-in-first-out). The feel should have some kind of a fadeIn and fadeOut. Here's what I managed to write till now: ... //Create a ul element with id 'ulele' and add it to a div ... //Do an ajax call and when an element arrives Hash = ComputeHash(message) if(!$("#" + Hash).exists()) { var element = $("<li></li>").html(message).attr('id', Hash).prependTo("#ulele"); $("#" + Hash).hide().delay(10000 - 1000 * messageNumber).show("slow"); _this.prune("#ulele"); } ... prune: function(divid) { $("#" + divid).children().each( function(i, elemLi) { if(i >= maxMessages) $(this).delay(10000).hide("slow").delay(10000).remove(); } ); } I've tried a couple of variations but the final effect I am getting is not that of a FIFO. The elements disappear instantaneously despite the delay and hide("slow") calls. Anyone has a more straightforward approach?

  • Environment Variable to determine the OS type (Windows XP, Windows 7)

    - by Santhosh
    I want to differrntiate between Windows XP and Windows 7 in a XML file. Thought i will use an environment variable for it inside the XML. However I could not find any system environment variable defined in windows that gives this information. I see the %OSTYPE% variable but it is only available in Windows 7. It is not defined in XP. Is there anyway i could do this? Note that i would like a solution which purely depends on system environment variables. I do not want to create new variables based on executing some command, because i want to use this variable in a XML file.

  • Warning: pointer of type 'void *' used in subtraction

    - by idealistikz
    Although it runs correctly, the following results in the aforementioned compiler warning: return ((item - (my->items))/(my->itemSize)); 'item' is a 'void *'; 'my-items' is a 'void *'; 'my-itemSize' is an 'int' Casting 'item' and 'my-items' as an 'int *' caused the program to run improperly. What is the best way to remove the warning?

  • Java weird generic return type

    - by drozzy
    Browsing through Guava libraries I saw this weird signature on a readLines method from Files class: public static <T> T readLines(File file, Charset charset, LineProcessor<T> callback) I know a little bit about generics in java, but this baffled me. What does the double T mean here? And why is the first one in angled brackets?

  • ChoiceFormat.setChoices confusion about format parameter type and documentation

    - by polygenelubricants
    From the java.text.ChoiceFormat API: setChoices(double[] limits, String[] formats): Set the choices to be used in formatting. Parameters: limits - contains [...] formats - are the formats you want to use for each limit. They can be either Format objects or Strings. When formatting with object Y, if the object is a NumberFormat, then ((NumberFormat) Y).format(X) is called. Otherwise Y.toString() is called. I'm having difficulties understanding the documentation for the formats parameter: how can you possibly pass a Format/NumberFormat object to setChoices if it's declared String[] formats? Note that interestingly, the getters counterpart of setChoices are declared as follows: double[] getLimits() Object[] getFormats() -- not String[]!!! Is this a bug in the API? Should the setter have been declared setChoices(double[], Object[]) instead, or am I not understanding how to use setChoices correctly?

  • Using std::ifstream to load in an array of struct data type into a std::vector

    - by Sent1nel
    I am working on a bitmap loader in C++ and when moving from the C style array to the std::vector I have run into an usual problem of which Google does not seem to have the answer. 8 Bit and 4 bit, bitmaps contain a colour palette. The colour palette has blue, green, red and reserved components each 1 byte in size. // Colour palette struct BGRQuad { UInt8 blue; UInt8 green; UInt8 red; UInt8 reserved; }; The problem I am having is when I create a vector of the BGRQuad structure I can no longer use the ifstream read function to load data from the file directly into the BGRQuad vector. // This code throws an assert failure! std::vecotr quads; if (coloursUsed) // colour table available { // read in the colours quads.reserve(coloursUsed); inFile.read( reinterpret_cast(&quads[0]), coloursUsed * sizeof(BGRQuad) ); } Does anyone know how to read directly into the vector without having to create a C array and copy data into the BGRQuad vector?

  • How to have type hinting in PHP that specifies variable scope inside of a template? (specifically PhpStorm)

    - by Lance Rushing
    I'm looking for a doc comment that would define the scope/context of the current php template. (similar to @var) Example View Class: <?php class ExampleView { protected $pageTitle; public function __construct($title) { $this->pageTitle = $title; } public function render() { require_once 'template.php'; } } -- <?php // template.php /** @var $this ExampleView */ echo $this->pageTitle; PHPStorm gives an inspection error because the access on $pageTitle is protected. Is there a hint to give scope? Something like: <?php // template.php /** @scope ExampleView */ // <---???? /** @var $this ExampleView */ echo $this->pageTitle;

  • Creating Instance of Python Extension Type in C

    - by Brad Zeis
    I am writing a simple Vector implementation as a Python extension module in C that looks mostly like this: typedef struct { PyObject_HEAD double x; double y; } Vector; static PyTypeObject Vector_Type = { ... }; It is very simple to create instances of Vector while calling from Python, but I need to create a Vector instance in the same extension module. I looked in the documentation but I couldn't find a clear answer. What's the best way to do this?
