• MVC Html Layout C# code formatting

  - by Andrew Florko

  I insert into asp.net mvc views C# logic that manages layout like the following: <% if (Model.People.Count > 0 ) { %> <% foreach (var person in Model.People) { %> ... <% }} else { %> <span class="error">Sorry, no people</span> <%} %> I try to minimize <% % code placing "{" symbol on the same line as it's condition (java-style). Html layout looks more clear to me after that. Do you apply C# formatting rules to <% % html injections "}" should be on a new line or manage layout in different way? Thank you in advance!

• Python breaks for a certain amount

  - by Brian Cox

  All, I am not very good at explaining so i will let my comments do it! #this script is to calculate some of the times table up to 24X24 and also miss some out #Range of numbers to be calculated numbers=range(1,25) for i in numbers: for w in numbers: print(str(i)+"X"+str(w)+"="+str(i*w)) #here i want to break randomly (skip some out) e.g. i could be doing the 12X1,12X2 and then 12X5 i have no limit of skips. Update Sorry if this is not clear i want it to break from the inner loop for a random amount of times

• PHP: How do I have a variable hhtp-header value for my GET request?

  - by Cortopasta

  I want the user to submit an answer to a question, then upon submission be redirected back to the page where they asked the question and I can't seem to get this to work: if (!isset($_POST['answer']) && !isset($_POST['verse'])) { echo "Please fill out form."; } elseif (!isset($_POST['answer']) || !isset($_POST['verse'])) { echo "one field left blank"; } else { $user->submitAnswer($question_id); header("Location: welcome.php?question_id=$question_id"); exit; } What am I doing wrong? EDIT: Sorry, wasn't very clear. I'm trying to pass the variable $question_id to the header(location: part so that it will pull up the question they were just on and show the answer they posted

• Js Variable Reference Quickie

  - by Nikki

  Hoping someone can clear this up for me. Let's say I have 2 globals: var myarray=[1,3,5,7,9],hold; and then I do this: function setup() { alert (myarray[0]);//shows 1 hold=myarray; alert (hold);//appears to show 'hold' containing all the values of myarray. first number shown is 1 myarray[0]=2; alert (hold);//shows the values of myarray with the updated first entry. first numbe shown is 2 } Am I to take it that 'hold' is simply keeping a reference to myarray, rather than actually taking all the values of?

• Proper design a Model-Controller in Cocoa?

  - by legege

  Hi, I'm trying to design a simple Cocoa application and I would like to have a clear and easy to understand software architecture. Of course, I'm using a basic MVC design and my question concerns the Model layer. For my application, the Model represents data fetched on the Internet with a XML-RPC API. I'm planning to use Core Data to represent a locally fetched version. How should the data be loaded initially? I'm reading the Cocoa Design Pattern book, and they talk about a Model-Controller that is centric to the Model. How would that be done? Thanks!

• In python, is there anyway to have a variable be a different random number everytime?

  - by woah113

  Basically I have this: import random variable1 = random.randint(13, 19) And basically what that does is assign variable1 a random number between 13 and 19. Great. But, what I want it to do is assign a different random number between 13 and 19 to that variable every time it is called. Is there anyway I can do this? If I'm not being clear enough here's an example: import random variable1 = random.randint(13, 19) print(variable1) print(variable1) print(variable1) And the output I want would look something like this: ./script.py 15 19 13 So yeah, anyway I could do this in python? (More specifically python3. but the answer would probably be similar to a python2 answer)

• Has anyone been successful at a assembler based led blinker for an xcore?

  - by dwelch

  I am liking the http://www.xmos.com chips but want to get a lower level understanding of what is going on. Basically assembler. I am trying to sort out something as simple as an led blinker, set the led, count to N clear the led, count to N, loop forever. Sure I can disassemble a 10 line XC program, but if you have tried that you will see there is a lot of bloat in there that is in every program, what bits are to support the compiler output and what bits are actually setting up the gpio?

• Improving HTML scrapper efficiency with pcntl_fork()

  - by Michael Pasqualone

  With the help from two previous questions, I now have a working HTML scrapper that feeds product information into a database. What I am now trying to do is improve efficiently by wrapping my brain around with getting my scrapper working with pcntl_fork. If I split my php5-cli script into 10 separate chunks, I improve total runtime by a large factor so I know I am not i/o or cpu bound but just limited by the linear nature of my scraping functions. Using code I've cobbled together from multiple sources, I have this working test: <?php libxml_use_internal_errors(true); ini_set('max_execution_time', 0); ini_set('max_input_time', 0); set_time_limit(0); $hrefArray = array("http://slashdot.org", "http://slashdot.org", "http://slashdot.org", "http://slashdot.org"); function doDomStuff($singleHref,$childPid) { $html = new DOMDocument(); $html->loadHtmlFile($singleHref); $xPath = new DOMXPath($html); $domQuery = '//div[@id="slogan"]/h2'; $domReturn = $xPath->query($domQuery); foreach($domReturn as $return) { $slogan = $return->nodeValue; echo "Child PID #" . $childPid . " says: " . $slogan . "\n"; } } $pids = array(); foreach ($hrefArray as $singleHref) { $pid = pcntl_fork(); if ($pid == -1) { die("Couldn't fork, error!"); } elseif ($pid > 0) { // We are the parent $pids[] = $pid; } else { // We are the child $childPid = posix_getpid(); doDomStuff($singleHref,$childPid); exit(0); } } foreach ($pids as $pid) { pcntl_waitpid($pid, $status); } // Clear the libxml buffer so it doesn't fill up libxml_clear_errors(); Which raises the following questions: 1) Given my hrefArray contains 4 urls - if the array was to contain say 1,000 product urls this code would spawn 1,000 child processes? If so, what is the best way to limit the amount of processes to say 10, and again 1,000 urls as an example split the child work load to 100 products per child (10 x 100). 2) I've learn that pcntl_fork creates a copy of the process and all variables, classes, etc. What I would like to do is replace my hrefArray variable with a DOMDocument query that builds the list of products to scrape, and then feeds them off to child processes to do the processing - so spreading the load across 10 child workers. My brain is telling I need to do something like the following (obviously this doesn't work, so don't run it): <?php libxml_use_internal_errors(true); ini_set('max_execution_time', 0); ini_set('max_input_time', 0); set_time_limit(0); $maxChildWorkers = 10; $html = new DOMDocument(); $html->loadHtmlFile('http://xxxx'); $xPath = new DOMXPath($html); $domQuery = '//div[@id=productDetail]/a'; $domReturn = $xPath->query($domQuery); $hrefsArray[] = $domReturn->getAttribute('href'); function doDomStuff($singleHref) { // Do stuff here with each product } // To figure out: Split href array into $maxChilderWorks # of workArray1, workArray2 ... workArray10. $pids = array(); foreach ($workArray(1,2,3 ... 10) as $singleHref) { $pid = pcntl_fork(); if ($pid == -1) { die("Couldn't fork, error!"); } elseif ($pid > 0) { // We are the parent $pids[] = $pid; } else { // We are the child $childPid = posix_getpid(); doDomStuff($singleHref); exit(0); } } foreach ($pids as $pid) { pcntl_waitpid($pid, $status); } // Clear the libxml buffer so it doesn't fill up libxml_clear_errors(); But what I can't figure out is how to build my hrefsArray[] in the master/parent process only and feed it off to the child process. Currently everything I've tried causes loops in the child processes. I.e. my hrefsArray gets built in the master, and in each subsequent child process. I am sure I am going about this all totally wrong, so would greatly appreciate just general nudge in the right direction.

• Using CreateFileMapping between to programs - C

  - by Jamie Keeling

  Hello, I have two window form applications written in C, one holds a struct consisting of two integers, another will receive it using the CreateFileMapping. Although not directly related I want to have three events in place so each of the processes can "speak" to each other, one saying that the first program has something to pass to the second, one saying the first one has closed and another saying the second one has closed. What would be the best way about doing this exactly? I've looked at the MSDN entry for the CreateFileMapping operation but I'm still not sure as to how it should be done. I didn't want to start implementing it without having some sort of clear idea as to what I need to do. Thanks for your time.

• Why for only some actions must I call setTarget?

  - by Max Pierce

  For most actions, I just click and drag in InterfaceBuilder to "wire up" a call from some interface object to my code. For example, if I want to know when the user single-clicks a row in a table, I drag a connection from the table's action to my controller's action. But now let's consider the user double-clicking a row. If I want one of my actions to be called when this happens, I need to call not only -[NSTableView setDoubleAction] but also -[NSControl setTarget]. Why? To be clear, I am not asking why Interface Builder doesn't support setDoubleAction. All tools have limitations. I am trying to gain a greater understanding about how and why setTarget doesn't seem to be necessary unless and until I want setDoubleAction to work. Another way to ask this question would be: Why don't I need to do anything in Interface Builder to set the target of the table's (single-click) action?

• Can I detect unused extra parameters passed to javascript methods?

  - by Pablojim

  In Javascript I can call any method with more than the necessary amount of parameters and the extra parameters are silently ignored. e.g. letters = ['a','b','c'] //correct letters.indexOf('a') //This also works without error or warning letters.indexOf('a', "blah", "ignore me", 38) Are there ways to detect cases where this occurs? My motivation is that in my experience cases where this occurs are usually bugs. Identification of these by code analysis or at runtime would help track these errors down. These cases are especially prevalent where people are expecting alterations to base types which may not have occurred. Logging a warning where this happens e.g. Date.parse('02--12--2012', 'dd--MM--YYYY') Notes: To be clear I would like a solution that doesn't involve me sprinkling checks all over my code and other peoples' code.

• 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?

• Is there a way to make XmlDocument parsing less strict

  - by Istrebitel

  I am making a program that will store its data in an XML file. When people write XML they can make subtle mistakes, like ending a comment with - so it looks like <!-- comment ---> or adding a </>inside an attribute. Naturally, the XML still can be read all right, but trying to input this text into XmlDocument will give a syntax error (and it wont be parsed). Is there a way to make XmlDocument less strict and make it ignore violations of the standard that do not make the document unparseable? For example, its clear that <!-- comment ---> is still a comment even though it contains - at the end which is against the standard specification).

• Export Sharepoint 2007 Custom List as RSS File

  - by matt

  Here's our scenario: We've created a sharepoint 2007 calendar on our intranet site We want to run a daily job to export a subset of the events to an rss file Another job will move the rss file to our public web site We have some funny restrictions where we can't simply publish the rss feed to the public. We have to go this export route. I'm not clear on how to accomplish step 2. Ideally, we wouldn't have to write a lot of custom code to accomplish this. Thanks.

• Kohana v2 - problem with routes

  - by yoda

  Hi, I'm attempting to set some custom routes in Kohana v2. What I'm looking for is some method that allow the system to : follow a pre-defined name to it's related root; redirect the non-matched url's into another controller; To give you a more clear view over the problem, I want the first url parameter to be associated to certain pages (contacts, home, services, about us, etc), and those urls who doesn't match the previous pages would be routed into a controller called products, in order to determine if the first url parameter regards a product name. Here's a sample of what I have : $config['_default'] = 'home'; $config['([a-zA-Z]+)'] = 'products/showcat/$1'; What am I missing here? Thanks in advance!

• Domain migration - 301 Redirect of all contentes of directory)

  - by Trufa

  Hi, I would like to know if it is possible to do the following considering that I would like to migrate domains. I have lets say: one.com/files/one.html one.com/files/two.php one.com/other/three.html one.com/other/four.doc one.com/other/subdirectory/five.doc I am migrating to two.com So I would like to make RESPECTIVE 301 redirects to the following: two.com/old/files/one.html two.com/old/files/two.php two.com/old/other/three.html two.com/old/other/four.doc two.com/old/other/subdirectory/five.doc I've tried with cPanel and although I come "close" with the redirects option I can't seem to make it happen. The folders are not much (10 -12) the file are a lot, and obviously impossible to make it manually. How would you proceed? Can this/ should this be done with regex from the .htaccess?? Can you direct all the elements of a subdirectory in the manner expressed above? I hope the question is clear enough, if not please ask for any clarification needed!! Thanks in advance!!

• Does Wicket hamper SEO or search engines ability to crawl?

  - by Nick

  We're coming from GWT projects and because of problems with SEO not liking GWT for our next project we're going to move clear of GWT (mainly because seo is a high priority for this next project). In choosing a new framework, I'm looking at Wicket and liking what I've seen so far. I've only done a few tutorials, but in looking at the war layout (from these tutorials) it looks like most of the html pages are in the WEB-INF folder. It this going to cause problems for SEO and search engines crawling through the sites files? Ideally, I'd like to use Wicket with some AJAX and deploy to Google App Engine.

• div with float next to div with width

  - by dragonfly

  Hi, I have html: <div class="field-label"><label>Email: </label></div> <div class="field"><input class="input" ......></div> and piece of css: .field-label { clear:left; float:left; padding:0.5em; width:6em; } .field { padding:0.5em; } And it worked fine. But for some elements I wanted to apply following change: when I add width to .field class layout goes to blazes: element with .field class appears under element with field-label class. Container of whole form is width enough to hold elements with field-label & field class. Why is it happening, did I miss something in css basics? Thanks ,Pawel

• Characteristics of an Initialization Vector

  - by Jamie Chapman

  I'm by no means a cryptography expert, I have been reading a few questions around Stack Overflow and on Wikipedia but nothing is really 'clear cut' in terms of defining an IV and it's usage. Points I have discovered: An IV is pre-pended to a plaintext message in order to strengthen the encryption The IV is truely random Each message has it's own unique IV Timestamps and cryptographic hashes are sometimes used instead of random values, but these are considered to be insecure as timestamps can be predicted One of the weaknesses of WEP (in 802.11) is the fact that the IV will reset after a specific amount of encryptions, thus repeating the IV I'm sure there are many other points to be made, what have I missed? (or misread!)

• Automatically "upgrade" user settings from previous version of app.config file?

  - by SqlRyan

  Every time I compile my app and the version number changes (I have an auto-incrementing build number), I lose the user-configured app.config settings, since they're stored in the AppData folder for a specific version. Essentially, every release of my application starts from scratch as far as user settings go. While this is a mild annoyance in development, it raises the question as I approach deployment/release - if I use the app.config to store my user settings, will the user's personalized settings be hosed every time they install a patch that changes the version number of my app? If so, is there an easy way to "upgrade" the settings from the previous release? I know that using HKCU in the registry is another option, but I like the ease of the My.Settings namespace, and I'd like to stay with app.config. Another SO question asks something similar, though the answer doesn't seem that clear. Will setting my MSI so it asks the user to upgrade be enough to preserve these user-level settings?

• Ruby on Rails updating join table records

  - by Eef

  Hey, I have two models Users and Roles. I have setup a many to many relationship between the two models and I have a joint table called roles_users. I have a form on a page with a list of roles which the user checks a checkbox and it posts to the controller which then updates the roles_users table. At the moment in my update method I am doing this because I am not sure of a better way: role_ids = params[:role_ids] user.roles.clear role_ids.each do |role| user.roles << Role.find(role) end unless role_ids.nil? So I am clearing all the entries out then looping threw all the role ids sent from the form via post, I also noticed that if all the checkboxes are checked and the form posted it keeps adding duplicate records, could anyone give some advice on a more efficent way of doing this?

• Does django take SCRIPT_NAME into account when using the default LOGIN_URL

  - by DanJ

  Hi, I'm using Django 1.0.2 and trying to figure out how to get the @login_required working correctly. When I use the built-in server it redirects to the default login_url, or my LOGIN_URL as defined in settings.py as expected. What is not clear to me is how to deploy to the server where my site is not at the root. In my templates I use the url template tag, and in the views I can access request.META['SCRIPT_NAME'], but for some reason it doesn't seem to apply to the LOGIN_URL used. What am I missing? Thanks.

• Average Rating script

  I have asked this once before but i didnt get a very clear answer. I need to know how to make a rating script for a site. I have a form that submits a rating out of ten to mysql. How would you get the average rating to be displayed from the mysql column using php? One person suggested having two tables; one for all the ratings, and one for the average rating of each page. Is there a simpler method than this?

• ASP.NET single quotes are converted to &#39;

  - by Monty

  Note: Most probably this will be a double question, but since I haven't found a clear answer, I'm asking it anyway. In ASP.NET I'd like to add some JavaScript to the onclick event of a CheckBox. I've simplified the case to this: <asp:CheckBox ID="TestCheckBox" runat="server" onclick="alert('test');" Text="Test" /> The resulting HTML is as follows: <input id="MainContainer_TestCheckBox" type="checkbox" name="ctl00$MainContainer$TestCheckBox" onclick="alert(&#39;test&#39;);" /><label for="MainContainer_TestCheckBox">Test</label> What particularly bothers me is that a single quote 'automatically' gets converted into '&#39;'. If I omit the onclick in the markup and assign it in Page_Load, the exact same results show in the HTML. protected void Page_Load(object sender, EventArgs e) { this.TestCheckBox.Attributes["onclick"] = "alert('test');"; } Anyone got a clue about what's happening? Or how to fix/ avoid it?
