  • Using NavigationService without XAML files

    - by UnclePaul
    I'm trying to create some pages in my Windows Phone application without the use of any XAML. Everything is working, however, I'm failing to use NavigationService/ Journal with this approach and all my attempts to utilize it are answered by the usual "No XAML was found at the location {0}'" response. Yes, I can add an almost empty XAML file to get everything working, but is this kind of boiler plate code really necessary? Is it maybe possible to use the UriMapping to map certain Uris to specific classes instead of *.xaml files?

  • Java compilation with two versions of Eclipse

    - by lepnio
    I've got an old project in Eclipse 2.1 and compiled with a JDK 1.4.2_12. I want to upgrade the version of Eclipse to Eclipse Galileo. I've imported my project and set the compilation level to 1.4 and I've also updated my build path to use the correct JDK. The problem is that when I compare the compiled files in the classes folder in the two versions of Eclipse, the MD5 checksum are different. Should I be worried about that fact or this is normal?

  • ASP.net MVC How to change the Textbox Class upon validation failure?

    - by Harry
    I notice in the default MVC template project that the Account registration fields are highlighted via a class change. I can't seem to get the same behavour out of my own code (in the same project - same CSS etc) What might be stopping this from occuring? Update I believe this relates to one of my other questions Because I was having trouble with NullReferenceExceptions I have changed the Html.ValidationMessage fields to have different names than the target fields. So really, I need to resolve this question

  • Cannot extend a class located in another file, PHP

    - by NightMICU
    I am trying to set up a class with commonly used tasks, such as preparing strings for input into a database and creating a PDO object. I would like to include this file in other class files and extend those classes to use the common class' code. However, when I place the common class in its own file and include it in the class it will be used in, I receive an error that states the second class cannot be found. For example, if the class name is foo and it is extending bar (the common class, located elsewhere), the error says that foo cannot be found. But if I place the code for class bar in the same file as foo, it works. Here are the classes in question - Common Class abstract class coreFunctions { protected $contentDB; public function __construct() { $this->contentDB = new PDO('mysql:host=localhost;dbname=db', 'username', 'password'); } public function cleanStr($string) { $cleansed = trim($string); $cleansed = stripslashes($cleansed); $cleansed = strip_tags($cleansed); return $cleansed; } } Code from individual class include $_SERVER['DOCUMENT_ROOT'] . '/includes/class.core-functions.php'; $mode = $_POST['mode']; if (isset($mode)) { $gallery = new gallery; switch ($mode) { case 'addAlbum': $gallery->addAlbum($_POST['hash'], $_POST['title'], $_POST['description']); } } class gallery extends coreFunctions { private function directoryPath($string) { $path = trim($string); $path = strtolower($path); $path = preg_replace('/[^ \pL \pN]/', '', $path); $path = preg_replace('[\s+]', '', $path); $path = substr($path, 0, 18); return $path; } public function addAlbum($hash, $title, $description) { $title = $this->cleanStr($title); $description = $this->cleanStr($description); $path = $this->directoryPath($title); if ($title && $description && $hash) { $addAlbum = $this->contentDB->prepare("INSERT INTO gallery_albums (albumHash, albumTitle, albumDescription, albumPath) VALUES (:hash, :title, :description, :path)"); $addAlbum->execute(array('hash' => $hash, 'title' => $title, 'description' => $description, 'path' => $path)); } } } The error when I try it this way is Fatal error: Class 'gallery' not found in /home/opheliad/public_html/admin/photo-gallery/includes/class.admin_photo-gallery.php on line 10

  • Finding an unnamed union in a struct::Haiku

    - by Freeman Lou
    So I have this assignment, and I have to find an unnamed union in struct _pthread_rwlock in pthread.h in the Haiku open source project. I began this assignment with some knowledge of c++ (past inheritance, polymorphism, and classes), but I find that what I learned do not help at all in my situation. I've opened the header file, and a source file named pthread_rwlock.cpp, and tried to look for the unnamed union, but there seems to be no unions in either file. What would be the correct way to find the problem?

  • looking for a javascript engine

    - by c0f33.alex
    i'm looking for a js engine to that I can (easily) expose C/C++ functions, classes etc. The API should allow changing exposed values from within C++ (by storing some kind of pointer or reference to an object inside js or so...). I've considered using google's v8 but I'm new to it and don't know whether it will satisfy my requirements. Can someone tell me whether I should stick to v8 or try something else?

  • Exposing members or make them private in Python?

    - by deamon
    Is there a general convention about exposing members in Python classes? I know that this is a case of "it depends", but maybe there is a rule of thumb. Private member: class Node: def __init__(self): self.__childs = [] def add_childs(self, *args): self.__childs += args node = Node() node.add_childs("one", "two") Public member: class Node2: def __init__(self): self.childs = [] node2 = Node2() node2.childs += "one", "two"

  • Excel VBA File not Found

    - by Brett
    During development of some Excel vba code about every other iteration where I go in and add some code then save the file, the next time I open the thing (it is automatically set to run the code on open) I get a spurious "File not Found" error. To fix it I copy all the code- modules and classes plus the startup code, to a fresh blank excel file save it and it runs fine. This happens in both Excel 2003 and 2007. What is happening here?

  • C# Type Casting at Runtimefor Array.SetValue

    - by sprocketonline
    I'm trying to create an array using reflection, and insert values into it. I'm trying to do this for many different types so would like a createAndFillArray function capable of this : Type t1 = typeof(A); Type t2 = typeof(B); double exampleA = 22.5; int exampleB = 43; Array arrA = createAndFillArray(t1, exampleA); Array arrB = createAndFillArray(t2, exampleB); private Array createAndFillArray(Type t, object val){ Array arr = Array.CreateInstance( t, 1); //length 1 in this example only, real-world is of variable length. arr.SetValue( val, 0 ); //this causes the following error: "System.InvalidCastException : Object cannot be stored in an array of this type." return arr; } with the class A being as follows: public class A{ public A(){} private double val; public double Value{ get{ return val; } set{ this.val = value; } } public static implicit operator A(double d){ A a = new A(); a.Value = d; return a; } } and class B being very similar, but with int: public class B{ public B(){} private double val; public double Value{ get{ return val; } set{ this.val = value; } } public static implicit operator B(double d){ B b = new B(); b.Value = d; return b; } } I hoped that the implicit operator would have ensured that the double be converted to class A, or the int to class B, and the error avoided; but this is obviously not so. The above is used in a custom deserialization class, which takes data from a custom data format and fills in the corresponding .Net object properties. I'm doing this via reflection and at runtime, so I think both are unavoidable. I'm targeting the C# 2.0 framework. I've dozens, if not hundreds, of classes similar to A and B, so would prefer to find a solution which improved on the createAndFillArray method rather than a solution which altered these classes.

  • Idiomatic scheme and generic programming, why only on numbers ?

    - by Skeptic
    Hi, In Scheme, procedures like +, -, *, / works on different types of numbers, but we don't much see any other generic procedures. For example, length works only on list so that vector-length and string-length are needed. I guess it comes from the fact that the language doesn't really offer any mechanism for defining generic procedure (except cond of course) like "type classes" in Haskell or a standardized object system. Is there an idiomatic scheme way to handle generic procedures that I'm not aware of ?

  • Add class to elements which already have a class

    - by bwstud
    I have a group of divs which I'm dynamically generating when a button is clicked with the class, "brick". This gives them dimension and starting position of top: 0. I'm trying to get them to animate to the bottom of the view using a css transition with a second class assignment which gives them a bottom position: 0;. Can't figure out the syntax for adding a second class to elements with a pre-existing class. On inspection they only show the original class of, "brick". HTML <!DOCTYPE html> <html> <head> <script src="http://code.jquery.com/jquery-2.1.0.min.js"></script> <meta charset="utf-8"> <title>JS Bin</title> </head> <body> <div id="container"> <div id="button" >Click Me</div> </div> </body> </html> CSS #container { width: 100%; height: 100vh; padding: 10vmax; } #button { position: fixed; } .brick { position: relative; top: 0; height: 10vmax; width: 20vmax; background: white; margin: 0; padding: 0; transition: all 1s; } .drop { transition: all 1s; bottom 0; } The offending JS: var brickCount = function() { var count = prompt("How many boxes you lookin' for?"); for(var i=0; i < count; i++) { var newBrick = document.createElement("div"); newBrick.className="brick"; document.querySelector("#container") .appendChild(newBrick); } }; var getBricks = function(){ document.getElementByClass("brick"); }; var changeColor = function(){ getBricks.style.backgroundColor = '#'+Math.floor(Math.random()*16777215).toString(16); }; var addDrop = function() { getBricks.brick = "getBricks.brick" + " drop"; }; var multiple = function() { brickCount(); getBricks(); changeColor(); addDrop(); }; document.getElementById("button").onclick = function() {multiple();}; Thanks!

  • New to MVC. Actionscript 3.0 Appreciate your help.

    - by Combustion007
    Hello Everyone, I am new to design patterns and am trying to learn the MVC implementation. I have written four classes: DataModel DataView DataController Main Main serves as the application facade. The main FLA is called HelloWorld. I have a symbol called "Box" in HelloWorld. I just would like to add an instance of the "Box" on the stage. Eventually I would like to place a button and when the button is clicked, the Box instance color will be changed. I would appreciate any help, please help me figure out what am I doing wrong. Here are my Classes: DATAMODEL CLASS: package { import flash.events.*; public class DataModel extends EventDispatcher { public static const UPDATE:String = "modelUpdate"; private var _color:Number = (Math.round(Math.random()* 0xffffff)); public function DataModel() { trace("DATA MODEL INIT"); } public function get color():Number { return _color; } public function set color(p:Number):void { _color = p; notifyObserver(); } public function notifyObserver():void { dispatchEvent(new Event(DataModel.UPDATE)); } } } //DATACONTROLLER CLASS: package { import flash.events.; import flash.display.; import flash.errors.*; public class DataController { private var _model:DataModel; public function DataController(m:DataModel) { trace("DATACONTROLLER INIT"); _model = m; } } } DATAVIEW CLASS: package { import flash.events.; import flash.display.; import flash.errors.*; public class DataView extends Sprite { private var _model:DataModel; private var _controller:DataController; private var b:Box; public function DataView(m:DataModel, c:DataController) { _model = m; _controller = c; b = new Box(); b.x = b.y = 100; addChild(b); } } } And Finally THE FACADE: package { import flash.display.; import flash.events.; import flash.text.; import flash.errors.; public class Main extends Sprite { private var _model:DataModel; private var _controller:DataController; private var _view:DataView; public function Main(m:DataModel, c:DataController, v:DataView) { _model = m; _controller = c; _view = v; addChild(v); } } } When I test the movie: I get this error: ArgumentError: Error #1063: Argument count mismatch on Main(). Expected 3, got 0. Thanks alot.

  • Using tinybutstrong templating system, how do I have a (secondary) mysql query (sub-block), inside a

    - by desbest
    This is the code that works well. $TBS->MergeBlock("items",$conn,"SELECT * FROM items WHERE categoryid = $getcategory"); and it has a good job of looping the items with no problem. <tr id="itemid_[items.id;block=tr]"> <td height="30"> <!-- <img src="move.png" align="left" style="margin-right: 8px;"> --> <div class="lowlight">[items.title] </div> </td> <td height="30"> <div class="editable" itemid="$item[id]">[items.quantity]</div> </td> <td height="30"> <!-- <img src="pencil.png" id="edititem"width="24" height="24"> --> &nbsp; &nbsp; &nbsp; &nbsp;<img src="icons/folder.png" id="category_[items.categoryid]";" class="changecategory" categoryid="[items.categoryid]" itemid="[items.id]" itemtitle="[items.title]" title="Change category" width="24" height="24"> &nbsp; &nbsp; &nbsp; &nbsp; <a href="index.php?category=[var.getcategory]&deleteitem=[items.id]" title="Delete item" onclick="return confirm('Are you sure you want to delete [items.title]?')"><img src="icons/trash.png" id="deleteitem" width="24" height="24"></a> </td> </tr> This is where the problem lies. In the table row I would like a secondary mysql merge block based on the id column that the primary (items) mysql table has. This means that ideally I would love to do this. $TBS->MergeBlock("fields",$conn,"SELECT * FROM items WHERE categoryid = [items.id]"); So then when I used [fields.value;block=div] inside the table row, it would pick up the a row from the fields table based on the primary mysql query. It would recognise what the id is for the merged block and perform a mysql query based on a variable that that block has. So that's what I would like to do and that's what I call a secondary mysql merge block. This is what I attempted by using the sub-blocks example and modifying it. index.html <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>TinyButStrong - Examples - subblocks</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <link href="tbs_us_examples_0styles.css" rel="stylesheet" type="text/css"> <style type="text/css"> <!-- .border02 { border: 2px solid #39C; } .border03 { border: 2px solid #396; } --> </style> </head> <body> <table width="400" align="center" cellpadding="5" cellspacing="0" style="border-collapse:collapse;"> <tr> <td class="border02"><strong>Item name:</strong> [item.title;block=tr] , <strong>Item quantity:</strong> [item.quantity]<br> <table border="1" align="center" cellpadding="2" cellspacing="0"> <tr bgcolor="#CACACA"> <td width="30"><u>Position</u></td> <td width="150"><u>Attribute</u></td> <td width="50"><u>Value</u></td> <td width="100"><div align="center"><u>Date Number</u></div></td> </tr> <tr bgcolor="#F0F0F0"> <td>[field.#]</td> <td>[field.attribute;block=tr;p1=[item.id]] <br><b>[item.id]</b> </td> <td><div align="right">[field.value]</div></td> <td><div align="center">[field.datenumber;frm='mm-dd-yyyy']</div></td> </tr> </table> </td> </tr> </table> </body> </html> index.php <?php require_once('../stockman-v3/tbs_class.php'); require_once('../stockman-v3/config.php'); // Create data $TeamList[0] = array('team'=>'Eagle' ,'total'=>'458'); //{ $TeamList[0]['matches'][] = array('town'=>'London','score'=>'253','date'=>'1999-11-30'); $TeamList[0]['matches'][] = array('town'=>'Paris' ,'score'=>'145','date'=>'2002-07-24'); $TeamList[1] = array('team'=>'Goonies','total'=>'281'); $TeamList[1]['matches'][] = array('town'=>'New-York','score'=>'365','date'=>'2001-12-25'); $TeamList[1]['matches'][] = array('town'=>'Madrid' ,'score'=>'521','date'=>'2004-01-14'); // } $TeamList[2] = array('team'=>'MIB' ,'total'=>'615'); // { $TeamList[2]['matches'][] = array('town'=>'Dallas' ,'score'=>'362','date'=>'2001-01-02'); $TeamList[2]['matches'][] = array('town'=>'Lyon' ,'score'=>'321','date'=>'2002-11-17'); $TeamList[2]['matches'][] = array('town'=>'Washington','score'=>'245','date'=>'2003-08-24'); // } $TBS = new clsTinyButStrong; $TBS->LoadTemplate('index3.html'); // Automatic subblock $TBS->MergeBlock("item",$conn,"SELECT * FROM items"); $TBS->MergeBlock("field",$conn,"SELECT * FROM fields WHERE itemid='[%p1%]' "); $TBS->MergeBlock('teamKEY',$TeamList); // Subblock with a dynamic query //$TBS->MergeBlock('match','array','TeamList[%p1%][matches]'); $TBS->MergeBlock("match",$conn,"SELECT * FROM fields WHERE id='[%p1%]' "); $TBS->Show(); ?> please note what i am trying to do If I was to change $TBS->MergeBlock("field",$conn,"SELECT * FROM fields WHERE itemid='[%p1%]' "); to... $TBS->MergeBlock("field",$conn,"SELECT * FROM fields"); It would show all the items.

  • HTML5 offline cache google font api

    I'm trying to create an offline HTML5 test application, and am playing with the new google fonts api at the same time. Does anyone have any ideas how to cache the remote fonts? Simply putting the api call in the cache manifest doesn't work, I assume this is because the api actually loads other files (ttf, eot, etc). Any ideas if using the font api offline would be possible? For reference this is the call I am making: http://fonts.googleapis.com/css?family=IM+Fell+English|Molengo|Reenie+Beanie
