• Get a random name and number (same contact) from an iPhone users address book

  - by Sam Jarman

  Hi there, I have had only very little experience using the address book in the iPhone SDK. Does anyone have a code snippet or knows the code to get a persons name and number Eg 'Fred Smith - 027 292 2112". I haven't had much luck with the stuff I've tried. I want to achieve this programmatically, and not let the user decide (random pick of the person). I also don't want to display the contact picker either any tutorial links, or anything would be appreciated. Thanks in advance Sam

• When to use MVC Scaffolding via NuGet vs MVC Scaffolding via MVC3 Tools Update

  - by James

  I am a little confused about the various different "mainstream" scaffolding options for MVC3. There is a NuGet package called MVCScaffolding. It first showed up in Jan 2011, but seems to be active and have recent updates, and be developed by Scott Hanselman, among others. Then in May 2011 came the MVC3 Tools Update. This seems like it incorporated the original scaffolding ideas into an "out of the box" scaffolding options. However, this has not been updated since. So - what is the relationship between these two scaffoldings (if any). Are there cases when one should be used over the other, or is it just a matter of taste? Does Visual Studio 2012 or MVC4 change the game on any of this? Thanks for any input.

• HTML stops at a PHP script made to connect to a mysql database. No errors printed.

  - by DavidR

  I'm trying to set up a login script for PHP using the tutorial on this site. The problem is that the site stops when it hits these lines, no error, no text: <?php $conn = mysql_connect('localhost', 'root', 'password') or die('error line7' . mysql_error()); mysql_select_db('mydb', $conn) or die('error line8' . mysql_error()); ?> If I take out these lines, the rest of the html runs perfectly. I've double checked my passwords and everything, nothing is working. I know very little about php and mysql other than what I've learned trying to set this up.

• Is there any framework for Windows Forms, DB driven application development/prototyping?

  - by dolzenko

  I'm writing simple database driven application, 80% of functionality is CRUD operations on about 15 tables. Coming from web development background I figured I can cover almost all of these CRUD cases with Rails scaffolding or say Django admins. So I started to look around for Rails/Django-like framework but for Windows Forms applications (ofcourse I understand that "rich client" application development significantly differs from a web development and I'm not expecting anything really similar). I was surprised that except for a variety of ORMs (let's call it Model-layer) it seems like I'm left with little choice when it comes to View-Controller layer. Maybe I'm missing something? PS. I evaluated Visual Studio DataSet Designer, but it seems to work only for the most simple cases, and requires additional code for any slightly nontrivial task. (added) so far I've found: TrueView for .NET (thanks to Vijay Patel) NConstruct

• jQuery DOM append losing markup

  - by Raj

  This is related to an earlier question. I try to append HTML DOM returned in an AJAX response to an existing DIV. I see all the text, but it seems all markup such as bold, italic, etc is lost. My AJAX (XML) data is like so: <event source="foo"> <contents> <h1>This is an event</h1> This is the body of the event </contents> </event> My jQuery code does this: $("#eventDiv").append( jData.find("contents").contents().clone() ); Attempting to do .html() on the cloned contents throws an exception: TypeError: Cannot call method 'replace' of undefined. I am a little surprised that it is so excruciatingly hard to do this with jQuery. Am I doing something too far off the track?

• Need to know who is hogging my bandwidth?

  - by Dev

  I have an ethernet connection to my iMac and with Internet sharing I am broadcasting the wireless network from my mac rather than using a wireless router. I use it to connect other devices wirelessly to the internet. But this makes all the traffic flow through my iMac. I wanted a way to analyze the traffic so that I know what connected devices are hogging the bandwidth at a given time and from which websites? I installed wireshark for mac and played around a little but it seems like an overkill when you first look at it. Can someone please help with few instructions to get what I need or any other way other than using wireshark? Thanks Dev.

• Magento Design Patterns

  - by JonB

  Magento, IMHO, represents a PHP system that is built on well thought-out coding principles - reuseable design patterns being one of them. In terms of an example of a PHP system, I think it can be considered pretty cutting edge and therefore worth considering from an architectural point of view. As I understand it, there are many design patterns that are available to the OOP developer. Seeing such patterns being put to use in an open-source system such as Magento allows a developer to view examples of such patterns in real use and in situ, rather than in examples that can sometimes be rather achedemic, and even a little misleading. As such, I am wondering what patterns, other than the ones I have listed below, Magento programmers have used when developing for Magento. As a note, I understand that some of these patterns are in place as a consequence of being built on the Zend Framework, MVC / Front Controller being a couple of them, The obvious ones are: Factory: $product = Mage::getModel('catalog/product'); Singleton: $category = Mage::getSingleton('catalog/session'); Registry: $currentCategory = Mage::registry('current_category');

• Best Website Statistics tool for Drupal

  - by Olav

  What is the best free Website statistics setup I can have for Drupal 6 on Apache? Particularities: 1. Multisite install. Might want to look over several sites. Should be able to restrict view for clients to their own site. Some hits are bypassing Drupal. Some urls are not public. Some sites have little traffic, it would be nice to be able to exclude "own" traffic. Logged in users are not so important (It seems Google Analytics is popular)

• Best way to order menu items injected by an IoC/plugin Framework

  - by Daver

  One of the common things I've seen done in applications built on IoC/plugin frameworks is to add commands to menus or toolbars from the dynamically loaded plugins. For example, the application's default plugins supply actions like "New, Open, Save" that show up in the context menu for a certain item in the workspace. A new plugin may add "Mail, Post, Encrypt" commands, but where do those commands show up in relation to "New, Open, Save"? How can the application that is loading components through IoC impose order on the items that get injected? Does it require metadata from the plugins that give a hint on how to group or order the items? Does it use a config file of previously known menu names (or ids) to define the order (seems a little weak to me)? Or are "unknown" plugins treated as second class citizens and always get dumped into sub menus? Something I've never even imagined (which I'm hoping to see in the answers)

• Best Place to Store Config Files and Log Files on Windows for My Program?

  - by Dave

  I need to store log files and config files for my application. Where is the best place to store them? Right now I'm just using the current directory, which ends up putting them in the Program Files directory where my program lives. The log files will probably be accessed by the user somewhat regularly, so %APPDATA% seems a little hard to get to. Is a directory under %USERPROFILE%\My Documents the best? It needs to work for all versions of Windows from 2000 forward.

• Passing HttpFileCollectionBase to the Business Layer - Bad?

  - by Terry_Brown

  hopefully there's an easy solution to this one. I have my MVC2 project which allows uploads of files on certain forms. I'm trying to keep my controllers lean, and handle the processing within the business layer of this sort of thing. That said, HttpFileCollectionBase is obviously in the System.Web assembly. Ideally I want to call to something like: UserService.SaveEvidenceFiles(MyUser user, HttpFileCollectionBase files); or something similar and have my business layer handle the logic of how and where these things are saved. But, it feels a little icky to have my models layer with a reference to System.Web in terms of separation of concerns etc. So, we have (that I'm aware of) a few options: the web project handling this, and my controllers getting fatter mapping the HttpFileCollectionBase to something my business layer likes passing the collection through, and accepting that I reference System.Web from my business project Would love some feedback here on best practice approaches to this sort of thing - even if not specifically within the context of the above.

• Moving to OOP hopefully!

  - by Luke

  So I am trying to understand OOP more and use it. The following code was written before i started using OOP. //loop through all the users $game = "$_POST[Game]_teams"; $result = mysql_query("SELECT username FROM `users`") or die(mysql_error()); while( $row=mysql_fetch_assoc($result) ) { $u[] = $row['username']; } I have put the query into my database page like following: function selectAllUsers() { $q = "SELECT username FROM ".TBL_USERS.""; mysql_query($q, $this->connection); } I'm a little confused about how the rest could be different? Would it be? Is it possible for anyone to help me without more code or understanding of my structure?

• Looking for some Feedback on a DB Design

  - by zSysop

  I'm currently working on a ticketing system which allows our users to submit tickets based on their own needs. i.e. if Department "A" is submitting a ticket they can have certain types of problem categories (such as "Supplies" or "Printer") along with details pertaining to the chosen category. I have laid out a partial db design and i was looking for some feedback on it. I've never built a system from the ground up by myself so i'm a little bit nervous. here's my a draft version of my db design Issues Table Id | CreatedBy | CreateDate | Status | Owner | AssignedTo | AssignmentDate | ----------------------------------------------------------------------------- EquipmentIssueDetails Table Id | IssueId | Serial # | Make | Model | .... --------------------------------------------- SupplyIssueDetails Table Id | IssueId | SupplyId | ItemId | QTY | UnitOfMeasurement ------------------------------------------------------------- NetworkIssueDetails Table Id | IssueId | Supervisor | Details | ------------------------------------------------------------- Notes Table Id | IssueId | Note | CreatedBy | CreateDate ------------------------------------------------------------- Thanks in advance

• How to flush output after each `echo` call?

  - by CuSS

  Hi all! I've a php script that only produces logs to the client. When I echo something, i wan't it to be transfered to client on-the-fly. (Because while the script is processing, the page is blank) I had already played arround with ob_start() and ob_flush(), but they didn't worked. What's the best solution? PS: it is a little dirty to put a flush at the end of the echo call... EDIT: Neither the Answers worked, PHP or Apache Fault? Thanks in advance, José Moreira Sorry for my bad English. ;)

• UX Design Question: Should a multi step wizard save the form contents when the user clicks 'go back'

  - by Ashwin Prabhu

  I am developing a web application that collects data over multiple steps through a wizard. Steps are generally not interdependent, in that data input at each step has little or no effect on the consequent steps. However each step may have a set of validations which determine whether the user can progress to the next step by clicking 'continue' What should be the behavior when the user clicks previous? a Quickly move to the previous page, thus losing all the unsaved data in the form. Prompting the user with a warning is an option, but it can become irritating quite soon. b Move to the previous page saving all the data in the current step - without triggering validations, so that when the user comes back she sees the form in the same state that she left it in. c any other behaviour All opinions are welcome :)

• ARC, worth it or not?

  - by MSK

  When I moved to Objective C (iOS) from C++ (and little Java) I had hard time understanding memory management in iOS. But now all this seems natural and I know retain, autorelease, copy and release stuff. After reading about ARC, I am wondering is there more benefits of using ARC or it is just that you dont have to worry about memory management. Before moving to ARC I wanted to know how worth is moving to ARC. XCode has "Convert to Objective C ARC" menu. Is the conversion is that simple (nothing to worry about)? Does it help me in reducing my apps memory foot-print, memory leaks etc (somehow ?) Does it has much testing impact on my apps ? What are non-obvious advantages? Any Disadvantage os moving to it?

• Is *not* using the asp.net membership provider a bad idea?

  - by EJB

  Is it generally a really bad idea to not use the built-in asp.net membership provider? I've always rolled my own for my asp.net apps (public facing), and really have not had any problems in doing so. It works, and seems to avoid a layer of complexity. My needs are pretty basic: once setup, the user must use email address and password to login, if they forget it, it will be emailed back to them (a new one). After setup there is little that needs to be done to each user account, but I do need to store several extra fields with each user (full name, telephone and a few other fields etc). The number of users that required login credentials are small (usually just the administrator and a few backups), and everyone else uses the site unauthenticated. What are the big advantages that I might be missing out on by skipping the asp.net membership provider functionality?

  I want to make a url query with date. I have confused a little : There is a mysql table: calDate : varchar The query : $sql="select * from calTbl"; $result = mysql_query($sql); while ($row = mysql_fetch_array($result)) { $n = str_replace("/", "",$row['calDate']); echo '<a href="index.php?p='.$n.'">'.$n.'</a>'; } I want to see related event from query. Can I set apart month, day and year from this? Or what is the correct table design here? Thanks in advance

• Is MVC now the only way to write PHP?

  - by JasonS

  Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

• Finding unique elements in an string array in C

  - by LuckySlevin

  Hi, C bothers me with its handling of strings. I have a pseudocode like this in my mind: char *data[20]; char *tmp; int i,j; for(i=0;i<20;i++) { tmp = data[i]; for(j=1;j<20;j++) { if(strcmp(tmp,data[j]))//then except the uniqueness, store them in elsewhere. } } But when i coded this the results were bad.(I handled all the memory stuff,little things etc.) The problem is in the second loop obviously :D. But i cannot think any solution. How do i find unique strings in an array. Example input : abc def abe abc def deg entered unique ones : abc def abe deg should be found.

• Helping managers and customers understand SOA

  - by David

  I frequently hear Service-Oriented Architecture (SOA) being tossed around as a buzzword among non-technical customers or program managers with little concern or understanding for what it actually entails (example: "Can I buy a SOA?"). There's also a lot of misinformation about SOA (example: "Only web apps can use SOA") and a general lack of understanding for its capabilities (example: "SOA can make your make all of your data work together"). What are some key facts that you, as someone who understand the technical side of SOA, use to educate program managers on the appropriate use and understanding of SOA? What's the best way to set the record straight with non-technical folks?

• How to get the "#" symbol in the :id into the redirect_to method in Rails

  - by Matthias Günther

  Hello, this is a silly questions but I don't understand, why rails isn't evaluating my string as expected. Here is my problem: I want to redirect to an url in the form ~/:controller/index/#_76 redirect_to :action => "index", :id => '#_76' But I'm getting the url in the form: ~/:controller/index/%25_76 and so my anchor for linking to a certain place in the website isn't working. Can someone please explain me, why rails makes this rendering? I think this hase something to do with url encoding. Again thanks for your help, I'm learning every day a little bit more about rails :).

• Drupal Hierarchical Content

  - by Vecta

  I am currently looking at using either the Taxonomy or CCK module on my Drupal site as a means to create a hierarchical system. However, I'm a little confused on which one would best suit my needs, or if there is something else that would work better. Basically, there will be probably 70 or so "mini-sites" on the website I'm working on, each with a landing page and about 5 sub-pages of detailed information. I need a way to mark those sub-pages as being sub-pages of their parent page, as well as create a menu system to navigate between them. What is the best way this could be done? Thanks for your input!

• GridView styling (CSS classes) disappears

  - by ProfK

  I'm migrating a large number of stand-alone pages into content pages. Most of this involves little more than copying and pasting a GridView from one page into the new page. However, I find that styling disappears in the new project, i.e. the styles (as classes) are still present in the stylesheet, but these classes are no longer applied to GridView table elements. Example, in the old project, once a table is rendered by the GridView, its header row has a class of HeaderStyle, but in the new project this is lost, without any editing of the GridView. Is there some mysterious, built-in mechanism that automatically applies these attributes to GridView elements that I have somehow disabled?
