  • Is there a config option in PHP to prevent undefined constants from being interpreted as strings?

    - by mrbinky3000
    This is from the php manual: http://us.php.net/manual/en/language.constants.syntax.php If you use an undefined constant, PHP assumes that you mean the name of the constant itself, just as if you called it as a string (CONSTANT vs "CONSTANT"). An error of level E_NOTICE will be issued when this happens. I really don't like this behavior. If I have failed to define a required constant, I would rather the script fail so that I am forced define it. Is there any way to force PHP to crash the script if it tries to use an undefined constant? For example. Both of these scripts do the same thing. <?php define('DEBUG',1); if (DEBUG) echo('Yo!'); ?> and <?php if(DEBUG) echo('Yo!'); ?> I would rather the second script DIE and declare that it tried to use an undefined constant DEBUG.

  • CREATE mysql database with default InnoDB tables?

    - by memilanuk
    Hello, I've been working on writing a SQL statement to create a MySQL database with several default options, including default character set and default collate. Is it possible to add syntax to make the default engine type for tables in this database to be innodb? I've been looking through the MySQL manual for v.5.1 and I've found the statement 'ENGINE=innodb' which would be appended to a CREATE TABLE statement... but I haven't found anything related to a CREATE DATABASE statement. Is there a normal way to do this as part of the database creation, or does it need to be specified on a table-by-table basis? Thanks, Monte

  • c# Attribute Question

    - by Petoj
    Well i need some help here i don't know how to solve this problem. the function of the attribute is to determine if the function can be run... So what i need is the following: The consumer of the attribute should be able to determine if it can be executed. The owner of the attribute should be able to tell the consumer that now it can/can't be executed (like a event). It must have a simple syntax. This is what i have so far but it only implements point 1, 3. [AttributeUsage(AttributeTargets.Method, AllowMultiple = false)] public class ExecuteMethodAttribute : Attribute { private Func<object, bool> canExecute; public Func<object, bool> CanExecute { get { return canExecute; } } public ExecuteMethodAttribute() { } public ExecuteMethodAttribute(Func<object, bool> canExecute) { this.canExecute = canExecute; } }

  • PHP - Cannot use Heredoc within a class method?

    - by Dan
    I'm writing the code for a controller method and I need to use it to send an email. I'm trying to use heredoc syntax to fill in the email body, however, the closing tag doesn't seem to be recognized. $this->email = new Email(); $this->email->from = 'Automated Email'; $this->email->to = '[email protected]'; $this->email->subject = 'A new user has registered'; $this->email->body = <<<EOF Hello, a new user has registered. EOF; $this->email->send(); Everything from the opening <<< EOF down (till the end of the file) is displayed as if it was in quotes. Can anyone see why this is not working? Any advice appreciated. Thanks.

  • Can't access dojo object property using string variable

    - by Kareem
    I am retrieving a json associative array using a dojo xhrGet request. The data comes back just fine, however I need the app to be able to display the keys and their properties (or values) without knowing the keys beforehand. So, I do the following: function getData() { dojo.xhrGet( { url: "ytd_process.php", handleAs: "json", load: function(response) { for (var key in response) { dojo.byId("boxes").innerHTML+="<div id=\"box\">"+key+":"+response.key+"</div>"; } console.dir(response); // Dump it to the console } }); }; The keys are retrieved and displayed on the page, but the response.key returns undefined. I know the syntax is correct because if I replace .key with an actual key value it will display correctly. It appears it doesn't like a string as the key. Any help or advice would be greatly appreciated. Thank you.

  • Making GWT application crawlable by a search engine.

    - by Philippe Beaudoin
    I want to use the #! token to make my GWT application crawlable, as described here: http://code.google.com/web/ajaxcrawling/ There is a GWT sample app available online that uses this, for example: http://gwt.google.com/samples/Showcase/Showcase.html#!CwRadioButton Will serve the following static webpage to the googlebot: http://gwt.google.com/samples/Showcase/Showcase.html?_escaped_fragment_=CwRadioButton I want my GWT app to do something similar. In short, I'd like to serve a different flavor of the page whenever the _escaped_fragment_ parameter is found in the URL. What should I modify in order for the server to serve something else (a static page, or a page dynamically generated through a headless browser like HTML Unit)? I'm guessing it could be the web.xml file, but I'm not sure. (Note: I thought of checking the Showcase app provided with the GWT SDK, but unfortunately it doesn't seem to support serving static files on _escaped_fragment_ and it doesn't use the #! token..)

  • Subversion terminology. Difference between projects, modules and root directories

    - by aioobe
    I'm setting up a repository for me and some colleagues. I have a subversion repository at hand, and all required rights. The usual directory-skeleton has been set up for me (branches, tags and trunk). Now I'm about to create a directory for me and my colleagues to put our files in. I'm quite sure the right place to put it is in trunk. Now here and there in tutorials, I see terms like "modules" and "projects" such as in Checking Out a Project - svn checkout svn checkout http://host_name/svn_dir/repository_name/project/trunk proj Is proj in the above line some glorified directory in trunk? Should I do something else than a checkout on trunk, mkdir and then commit when creating a directory for me and my colleagues? Whats the difference between a project, a directory in trunk and a module?

  • Insert xelements using LINQ Select?

    - by Simon Woods
    I have a source piece of xml into which I want to insert multiple elements which are created dependant upon certain values found in the original xml At present I have a sub which does this for me: <Extension()> Public Sub AddElements(ByVal xml As XElement, ByVal elementList As IEnumerable(Of XElement)) For Each e In elementList xml.Add(e) Next End Sub And this is getting invoked in a routine as follows: Dim myElement = New XElement("NewElements") myElement.AddElements( xml.Descendants("TheElements"). Where(Function(e) e.Attribute("FilterElement") IsNot Nothing). Select(Function(e) New XElement("NewElement", New XAttribute("Text", e.Attribute("FilterElement").Value)))) Is it possible to re-write this using Linq syntax so I don't need to call out to the Sub AddElements but could do it all in-line Many Thx Simon

  • Increment global variable on click in flash, actionscript 3

    - by msandbot
    Hi, Making a flash page that can cycle through these three images on mouseclick. For some reason the local changes to count are not reflected on the global one. I tried _global but the syntax was odd and gave me errors. How should I implement this? import flash.events.Event; var images:Array = ["images/image.jpg", "images/image2.jpg", "images/image3.jpg"]; var count:int = 0; forward.addEventListener(MouseEvent.CLICK, loadPhoto); function loadPhoto(evt:Event){ if(count>2){ count==0; } trace(count); imageFrame.source = images[count]; count++; }

  • How to maintain tabs when pasting in Vim

    - by Ant Wilson
    I use the tab key to indent my python code in Vim, but whenever I copy and paste a block Vim replaces every tab with 4 spaces, which raises an IndentationError I tried setting :set paste as suggested in related questions but it makes no difference Other sites suggest pasting 'tabless' code and using the visual editor to re-indent, but this is asking for trouble when it comes to large blocks Are there any settings I can apply to vim to maintain tabs on copy/paste? Thanks for any help with this :) edit: I am copying and pasting within vim using the standard gnome-terminal techniques (ctrl+shift+c / mouse etc.) my .vimrc is: syntax on set ts=4 if has("terminfo") let &t_Co=8 let &t_Sf="\e[3%p1%dm" let &t_Sb="\e[4%p1%dm" else let &t_Co=8 let &t_Sf="\e[3%dm" let &t_Sb="\e[4%dm" endif I looked up that ts - Sets tab stops to n for text input, but don't know what value would maintain a tab character

  • C# Language Design: explicit interface implementation of an event

    - by ControlFlow
    Small question about C# language design :)) If I had an interface like this: interface IFoo { int Value { get; set; } } It's possible to explicitly implement such interface using C# 3.0 auto-implemented properties: sealed class Foo : IFoo { int IFoo.Value { get; set; } } But if I had an event in the interface: interface IFoo { event EventHandler Event; } And trying to explicitly implement it using field-like event: sealed class Foo : IFoo { event EventHandler IFoo.Event; } I will get the following compiler error: error CS0071: An explicit interface implementation of an event must use event accessor syntax I think that field-like events is the some kind of dualism for auto-implemented properties. So my question is: what is the design reason for such restriction done?

  • Deserialize XML to custom Class in Flex?

    - by MysticEarth
    Is it possible to deserialize an XML file to a class in Flex without manually checking the XML and/or creating the class, with the help of a HttpService? Edit: Explained a bit more and better. We have an XML file which contains: <Project> <Name>NameGoesHere</Name> <Number>15</Number> </Project> In Flex we want this to be serialized to our Project class: package com.examplepackage { import mx.collections.ArrayCollection; [XmlClass] public class Project { public var Name:String; public var Number:int; public function Project() { } } } The XML is loaded with a HTTPService.

  • ASP.NET MVC authorization & permission to use model classes

    - by Tomek
    Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?

  • Abstract Forms using WinForms

    - by pm_2
    I’m trying to achieve a similar affect in a WinForms application as a master form does with ASP.NET. My initial thoughts on this were to create a base form and declare it as abstract, but the compiler doesn’t seem to let me do this. public abstract partial class Master : Form { public Master() { InitializeComponent(); } } So I have two questions: Why will the compiler not let me do this? Am I using the wrong syntax or is this a genuine restriction. Can anyone suggest a workaround or better way to do this? EDIT: InitializeComponent code: private void InitializeComponent() { this.components = new System.ComponentModel.Container(); this.mainMenu1 = new System.Windows.Forms.MainMenu(); this.Menu = this.mainMenu1; this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi; this.Text = "Master"; this.AutoScroll = true; }

  • nHibernate HQL dynamic Instantiation question

    - by Rey
    Hello all, I can't find what's going on with the following nHibernate HQL. here's my VB.Net code: Return _Session.GetNamedQuery("PersonAnthroSummary").SetInt32(0, 2).UniqueResult() My Named Query: <sql-query name="PersonAnthroSummary"> select New PersonAnthroSummary( Anthro.Height, Anthro.Weight ) from PersonAnthroContact as Anthro where Anthro.ID = ? </sql-query> and i am importing the DTO class: <import class="xxxxxxx.DataServices.PersonAnthroSummary, xxxxxxxxx.DataServices"/> PersonAnthroSummary has a constructor that will take height and weight arguments. when i test this, nHibernate throwing following exception: {"Incorrect syntax near 'Anthro'."} and generated QueryString is: "select New PersonAnthroSummary( Anthro.Height, Anthro.Weight ) from PersonAnthroContact as Anthro where Anthro.ID = @p0" Can some one tell me what i'm doing wrong here?

  • How do I build mDNSResponder?

  • Left outer join null using VB.NET and LINQ

    - by jvcoach23
    I've got what I think is a working left outer join LINQ query, but I'm having problems with the select because of null values in the right hand side of the join. Here is what I have so far Dim Os = From e In oExcel Group Join c In oClassIndexS On c.tClassCode Equals Mid(e.ClassCode, 1, 4) Into right1 = Group _ From c In right1.DefaultIfEmpty I want to return all of e and one column from c called tClassCode. I was wondering what the syntax would be. As you can see, I'm using VB.NET. Update... Here is the query doing join where I get the error: _message = "Object reference not set to an instance of an object." Dim Os = From e In oExcel Group Join c In oClassIndexS On c.tClassCode Equals Mid(e.ClassCode, 1, 4) Into right1 = Group _ From c In right1.DefaultIfEmpty Select e, c.tClassCode If I remove the c.tClassCode from the select, the query runs without error. So I thought perhaps I needed to do a select new, but I don't think I was doing that correctly either.

  • Difference between piping a file to sh and calling a shell file

    - by Peter Coulton
    This is what was trying to do: $ wget -qO- www.example.com/script.sh | sh which quietly downloads the script and prints it to stdout which is then piped to sh. This unfortunately doesn't quite work, failing to wait for user input a various points, aswell as a few syntax errors. This is what actually works: $ wget -qOscript www.example.com/script.sh && chmod +x ./script && ./script But what's the difference? I'm thinking maybe piping the file doesn't execute the file, but rather executes each line individually, but I'm new to this kind of thing so I don't know.

    I'm trying to make a random image appear on the press of a button. So it generates a random number, and the switch algorithm swaps the chosen image with the one in the imgview. but I want a switch in the settings app to toggle which set of images to use. I know pretty much how to do it...it's just that it doesn't work. I'm missing some syntax thing...Please help, stackoverflow? it's my birthday. int Number = rand() %30; NSString *toggleValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"enabled_preference"]; switch (Number) { if (*toggleValue == 0) { case 0: picture.image = [UIImage imageNamed:@"1.png"]; break; case 1: picture.image = [UIImage imageNamed:@"2.png"]; break;} else { case 0: picture.image = [UIImage imageNamed:@"3.png"]; break; case 1: picture.image = [UIImage imageNamed:@"4.png"]; break;} }

  • Correct sequence of actions when using Markdown & MySQL?

    - by Andrew Heath
    I want my users to be able to write an article in Markdown, have it stored in the MySQL database (with the option to edit it in the future), and displayed for other users. In practice, this is my understanding of how it works: INPUT user input via HTML form using Markdown syntax $queryInput = mysql_real_escape_string($userInput); insert sanitized string into database OUTPUT query field from database $output = Markdown($queryResult); display $output Is that it? Does PHP Markdown preclude the need for htmlspecialchars or Pure HTML ? Thanks!

  • LINQ: Dot Notation vs Query Expression

    - by Martín Marconcini
    I am beginning to use LINQ in general (so far toXML and toSQL). I've seen that sometimes there are two or more ways to achieve the same results. Take this simple example, as far as I understand both return exactly the same thing: SomeDataContext dc = new SomeDataContext(); var queue = from q in dc.SomeTable where q.SomeDate <= DateTime.Now && q.Locked != true orderby (q.Priority, q.TimeCreated) select q; var queue2 = dc.SomeTable .Where( q => q.SomeDate <= DateTime.Now && q.Locked != true ) .OrderBy(q => q.Priority) .ThenBy(q => q.TimeCreated); Besides any mistake I may have made in the syntax or a missing parameter or difference, the idea is that there are two ways to express the same thing; I understand that the first method has some limitations and that the "dot notation" is more complete, but besides that, are there any other advantages?

  • What C#/SQL Server feature did someone show you that made you say Wow!

    - by Randy Minder
    It's late Friday afternoon, and my mind is checking out for the week. So I thought I'd ask a light-hearted, interesting, question. Yesterday a co-worker showed me how he managed to save quite a bit of code and improve code reuse through the use of an anonymous delegate and the use of the Action function. My first thought was, "Wow, I had no idea you could do that!". I'm curious what sort of things someone showed you, either in c# or SQL Server, that made you stop and think, "Wow!". Randy

  • ASP.NET MVC reminds me of old Classic ASP spaghetti code...

    - by EdenMachine
    I just went through some MVC tutorials after checking this site out for a while. Is it just me, or does MVC View pages brinig back HORRIBLE flashbacks of Classic ASP spaghetti code with all the jumping in and out of HTML and ASP.NET with yellow delimiters everywhere making it impossible to read? What ever happened to the importance of code/design separation?? I was really sold on the new technology until the tutorials hit the View page development section. Or am I missing something? (And don't say you can use the template to help because it's jsut moving the spaghetti to another location - sweeps it under the rug - it doesn't fix the problem)

  • Get clientid in user control from external javascript file

    - by Giorgi
    Hello, I am developing a user control (ascx) in ASP.NET which uses javascript for manipulating controls. Currently the javascript code is inlined and uses <%= somecontrol.ClientID %> to get the control it needs. I want to put the javascript file in external file but from external file I cannot use the above syntax for retrieving controls. I have read about possible solutions in this and this answers but the problem is that the user control can be placed multiple times on page. This means that the Controls array (mentioned in the answers) will be rendered several times with different items. As a result the script will not be able to retrieve the id it needs. If I put <%= ClientId %> in the name of array that holds items then I will have the same problem as I am trying to solve. Any ideas?
