  • Can you reverse order a string in one line with LINQ or a LAMBDA expression

    - by Student for Life
    Not that I would want to use this practically (for many reasons) but out of strict curiousity I would like to know if there is a way to reverse order a string using LINQ and/or LAMBDA expressions in one line of code, without utilising any framework "Reverse" methods. e.g. string value = "reverse me"; string reversedValue = (....); and reversedValue will result in "em esrever" EDIT Clearly an impractical problem/solution I know this, so don't worry it's strictly a curiosity question around the LINQ/LAMBDA construct.

  • REST/JSON: Should I include a newline after the JSON string?

    - by Mark Harrison
    If I'm returning ["foo"] from a RESTful web query, Which of these is more proper? Will pedantic REST parsing die on the newline? ["foo"]\n (with newline, Content-Length=8) ["foo"] (no newline, Content-Length=7) For easy regression testing I like the form with the newline, but I want to make sure I won't be breaking any application frameworks that might have a more strict view of the REST format.

  • Common one-to-many table for multiple entities

    - by Ben V
    Suppose I have two tables, Customer and Vendor. I want to have a common address table for customer and vendor addresses. Customers and Vendors can both have one to many addresses. Option 1 Add columns for the AddressID to the Customer and Vendor tables. This just doesn't seem like a clean solution to me. Customer Vendor Address -------- --------- --------- CustomerID VendorID AddressID AddressID1 AddressID1 Street AddressID2 AddressID2 City... Option 2 Move the foreign key to the Address table. For a Customer, Address.CustomerID will be populated. For a Vendor, Address.VendorID will be populated. I don't like this either - I shouldn't need to modify the address table every time I want to use it for another entity. Customer Vendor Address -------- --------- --------- CustomerID VendorID AddressID CustomerID VendorID Option 3 I've also seen this - only 1 foreign key column on the Address table with another column to identify which foreign key table the address belongs to. I don't like this one because it requires all the foreign key tables to have the same type of ID. It also seems messy once you start coding against it. Customer Vendor Address -------- --------- --------- CustomerID VendorID AddressID FKTable FKID So, am I just too picky, or is there something I haven't thought of?

  • TFS: Choose which Team Project to add a solution too.

    - by Patricker
    I have a solution which I developed in VS2008 and which I am trying to add to Source Control (TFS 2010, though the issue happened in TFS 2008 as well). I have several TFS workspaces on my computer and I have access to several Team Projects. When I right click the solution in my Solution Explorer and choose the "Add Solution to Source Control" option I am never given an option of choosing which Workspace or which Team Project to add the existing solution too. VS2008 then proceeds to add it to the same team project every time. I have tried selecting an alternate workspace/team project in every window where I can see an option for it but it always adds it back to the same one. I even tried changing the name of my new workspace so that alphabetically it was the first thinking that it might be somehow related to that... no luck. I then tried goign to the Change Source Control window where you can add/remove bindings on a solution/project but that window also defaults to the same Team Project as trying to add the solution directly does... Any help would be greatly appreciated with this, maybe I'm just missing something?

  • PHP: Retrieving JSON via jQuery ajax help

    - by iamjonesy
    Hey I have a script that is creating and echoing a JSON encoded array of magento products. I have a script that calls this script using jQuery's ajax function but I'm not getting a proper response. This is the script that creates the array: $collection = Mage::getModel('catalog/product')->getCollection(); $collection->addAttributeToSelect('name'); $collection->addAttributeToSelect('price'); $products = array(); foreach ($collection as $product){ $products[$product->getPrice()] = $product->getName(); } header('Content-Type: application/x-json; charset=utf-8'); echo(json_encode($products)); Here is my jQuery: <select id="products"> <option value="#">Select</option> </select> <script type="text/javascript"> jQuery.noConflict(); jQuery(document).ready(function(){ jQuery.ajax({ type: "GET", url: "http://localhost.com/magento/modules/products/get.php", dataType: "json", success: function(products) { jQuery.each(products,function(price,name) { var opt = jQuery('<option />'); opt.val(name); opt.text(price); jQuery('#products').append(opt); }); } }); }); </script> I'm getting a response from this but I'm not seeing a any JSON. I'm using firebug. I can see there has been a JSON encoded response but the response tab is emtyp and my select boxes have no options. Can anyone see and problems with my code? Here is the response I should get: {"82.9230":"Dummy","177.0098":"Dummy 2","76.0208":"Dummy 3","470.6054":"Dummy 4","357.0083":"Dummy Product 5"} Thanks, Billy

  • Verilog linting tools?

    - by mrflibble
    What are your favorite linting tools for verilog? I am currently looking for a good verilog linting tool. And preferably one that can be configured to either handle or ignore certain vendor specific primitives like LUT's, PLL's, etc. I recently tried verilator-3.810, but out of the box it needs a little help with the primitives. So what (linting) tools do you use to deal with the not-so-strict syntax of verilog?

  • What is the right way to structure HTML and CSS?

    - by Meke
    So, I'm a script monkey at the core. Lately I seem to get stuffed into doing design too for some odd reason and, well, let's just say I should probably have studied better. Either way - What I ask is, what's the Right way to structure a website? This one has a header with links, then a block with tabs, right under another block which consists of two parts and under those a few others who I'm not at yet. However, the thing is, I need to make a block that consists of two parts that are in the same box but structured independently. I'll try to draw it up. Browser window..................-[]X ------------------------------------ |.................Header Links Here| ||Tab|Tab|Tab|_____________........| ||Tab content.............|Small...| ||........................|Section.| ||---Line signing new section------| ||........................|Another.| ||..Content Area..........|Small...| ||........................|Section.| ------------------------------------ My issue is in the division of small sections and tab/content areas. I tried using floats, making them as tables, aligning and whatnot. The putting float:left on both tables worked. Kinda. Until I tried to resize the window. So, how do you PROPERLY structure a site like this? three divs and tables? Something else? I'll clarify this again: It's the Code to use to create the look above that I'm trying to figure out the proper way to do, not the design As requested here's the current structure I have <div class="container"> <div class="topBlock"> //Header Links Here </div> <div class="inputBlock"> <ul id="tabs"> <li><a href="#strict">Strict</a></li> <li><a href="#flex">Flex</a></li> <li><a href="#multiStep">Multi-Step</a></li> </ul> <div id="strict" class="tabContent"> <table class="tableLeft"> <tr> <td>From</td> </tr> <tr> <td><input id="inputBlockFrom" type="text" placeholder="FROM"/></td> </tr> <tr> <td>To</td> </tr> <tr> <td><input id="inputBlockTo" type="text" placeholder="TO"/></td> </tr> </table> <table class="tableRight"> <tr> <td>Leave</td> </tr> <tr> <td><input id="inputBlockLeave" type="text" name="leave" placeholder="LEAVE"/></td> <td><input id="inputBlockOne" type="radio" name="one"/></td> <td>One</td> </tr> <tr> <td>Return</td> </tr> <tr> <td><input id="inputBlockReturn" type="text" name="return" placeholder="RETURN"/></td> <td><input id="inputBlockBut" type="radio" name="one" checked/></td> <td>Return</td> </tr> <tr> <td><input id="inputBlockSubmit" type="submit" value="Search"/></td> </tr> </table> </div> <div id="flex" class="tabContent"> Test Two </div> <div id="multiStep" class="tabContent"> Test Three </div> </div> <div class="mapBlock tabContent"> <table class="tableLeft"> <tr><td> <div id="map" class="google_map"></div> </td></tr> </table> <table class="tableRight smallTable"> <tr> <td>Distance</td> </tr> <tr> <td>[-------------|------------]</td> //Slider to be </tr> </table> <table class="tableRight smallTable"> <tr> <td>Choice / Choice</td> </tr> </table> <table class="tableRight"> <tr> <td>Show:</td> </tr> <tr> <td><input type="radio"/></td> <td>Price</td> <td><input type="radio"/></td> <td>Button!</td> </tr> <tr> <td><input type="radio"/></td> </tr> <tr> <td><input type="radio"/></td> </tr> </table> </div> </div> </body> Sorry if it's messed up in the whitespacing somewhere.. The CSS: body { font-size: 80%; font-family: 'Lucida Grande', Verdana, Arial, Sans-Serif; background-color: #e2edff; } .container { margin: 5px 5px 5px 5px; padding: 5px 5px 5px 5px; } .pageBlock { /* To future me: This class is for One Full Screen ideas */ min-height: 300px; } .topBlock { text-align: right; color: #000000; } .topBlock a { text-decoration: none; color: #000000; } .tableLeft { width: 75%; float: left; border-right: dotted 2px black; } .tableRight { float: left; overflow: auto; } .smallTable { border-bottom: 1px dotted #c9c3ba; } .google_map { height: 270px; width: 100%; }

  • JQuery selfbuild plugin question - default value is overwritten.

    - by Bruno
    Hi jQuery ninjas. I need your help. I have made a really clean and simple example to illustrate my problem. I have build my own jquery plugin: (function($) { $.fn.setColorTest = function(options) { options = $.extend($.fn.setColorTest.defaults,options); return this.each(function() { $(this).css({ 'color': options.color}); }); } $.fn.setColorTest.defaults = { color: '#000' }; })(jQuery); As you can see I'm setting a default color and making it possible for the user to change it. My problem/question is: I have two paragraphs on the same page where I want to use the default color for the first and a different color for the second paragraph: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Color Test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $('a#click').click(function() { $('#test1').setColorTest(); }); $('a#click2').click(function() { $('#test2').setColorTest({color: '#fff666'}); }); }); </script> </head> <body> <a id="click">click here</a> <a id="click2">click here2</a> <p id="test1">Test 1</p> <p id="test2">Test 2</p> </body> </html> My problem is that if I click on the second paragraph (p) that overrides the default color and afterwards clicks on the first p it will use the overwritten color and not the default color for the first p. How can I ensure that the first p always will use the default color? I know I can just define the color for the first p as well but that is not an option here $('#test1').setColorTest('color': '#000'); So what to do?

  • Assign Multiple Custom User Roles to a Custom Post Type

    - by OUHSD Webmaster
    Okay here's the situation.... I'm working on a my business website. There will be a work/portfolio area. "Work" is a custom post type. "Designer" is a custom user role. "Client" is a custom user role. In creating a new "Work" post I would like to be able to select both a "designer" and "Client" to assign to the piece of work, as I would assign an author to a regular ol' post. I tried the method from this answer but it did not work for me. ) I placed it in my functions.php file. ` add_filter('wp_dropdown_users', 'test'); function test($output) { global $post; //Doing it only for the custom post type if($post->post_type == 'work') { $users = get_users(array('role'=>'designer')); //We're forming a new select with our values, you can add an option //with value 1, and text as 'admin' if you want the admin to be listed as well, //optionally you can use a simple string replace trick to insert your options, //if you don't want to override the defaults $output .= "<select id='post_author_override' name='post_author_override' class=''>"; foreach($users as $user) { $output .= "<option value='".$user->id."'>".$user->user_login."</option>"; } $output .= "</select>"; } return $output; } ` Any help would be extremely appreciated!

  • Application Design: Single vs. Multiple Hits to the DB

    - by shyneman
    I'm building a service that performs a set of configured activities based on the type of request that it receives. Each activity involves going to the database and retrieving/updating some kind of information. The logic for each activity can be generalized and re-used across different request types. The activities may need to participate in a transaction for the duration of the servicing the request. One option, I'm considering is having each activity maintain its own access to DAL/database. This fully encapsulates the activity into a stand-alone re-usable piece, but hitting the database multiple times for one request doesn't seem like a viable option. I don't really know how to easily implement the concept of a transaction across the multiple activities here either. The second option is to encapsulate ALL the activities into one big activity and hit the database once. But this does not allow re-use and configuration of these activities for different requests. Does anyone have any suggestions and input about what should be the best way to approach my problem? Thanks for any help.

  • how to generate unique numbers less than 8 characters long.

    - by loudiyimo
    hi I want to generate unique id's everytime i call methode generateCustumerId(). The generated id must be 8 characters long or less than 8 characters. This requirement is necessary because I need to store it in a data file and schema is determined to be 8 characters long for this id. Option 1 works fine. Instead of option 1, I want to use UUID. The problem is that UUID generates an id which has to many characters. Does someone know how to generate a unique id which is less then 99999999? option 1 import java.util.HashSet; import java.util.Random; import java.util.Set; public class CustomerIdGenerator { private static Set<String> customerIds = new HashSet<String>(); private static Random random = new Random(); // XXX: replace with java.util.UUID public static String generateCustumerId() { String customerId = null; while (customerId == null || customerIds.contains(customerId)) { customerId = String.valueOf(random.nextInt(89999999) + 10000000); } customerIds.add(customerId); return customerId; } } option2 generates an unique id which is too long public static String generateCustumerId() { String ownerId = UUID.randomUUID().toString(); System.out.println("ownerId " + ownerId); return ownerId }

  • Inserting an element within jQuery Validation plugin's error template

    - by simshaun
    I'm utilizing the jQuery Validation plugin for my form. It lets you change the errorElement and wrap the errorElement using with the wrapper option. But, I want to insert an element within errorElement like this: <label class="error"><em></em>Error message goes here</label> Is there an easy way to accomplish inserting the em tag? I've tried prepending the em tag using the errorPlacement option (see below), but it seems the plugin is replacing the contents of errorElement afterwards. $.validator.setDefaults({ errorPlacement: function(error, element) { error.prepend('<em/>'); error.insertBefore(element); } }); I've also tried prepending the em tag using the showErrors option (see below). Again, it seems the plugin is replacing the contents of errorElement afterwards. $.validator.setDefaults({ showErrors: function(errorMap, errorList) { for (var i = 0; i < errorList.length; i++) { var error = errorList[i], $label = this.errorsFor(error.element), $element = $(error.element); if ($label.length && $label.find('em').length == 0) { $label.prepend('<em/>'); } } this.defaultShowErrors(); } }); I've also tried modifying the plugin so that when the error element is generated, the <em> tag is prepended. That works until I focus on a form element that has an error, after which the em tag is removed. (It's doing this because jQuery validation is constantly updating the contents of the error element as I focus and/or type in the field, therefore erasing my em tag added at error-element creation.)

  • Javascript Function for related select elements onSubmit

    - by Livingston
    I am trying to create (4) Select elements within a form element. Each select element has a different number of options. So if a user click one option on Select #1 and then click another option on Select #2, after hitting submit they will be taken to www.blah.com/option1/option2 page which will display the filtered results. Or they can chose an option from all 4 select menus and be taken to option1/option2/option3/option4 page. The categories are all related .Select #1 is a category, Select #2 is a subcategory of 1, Select #3 is a subcategory of #2 and Select #4 is a subcategory of #3. A great example would be on (LINK) http://www.safavieh.com/rugs (LINK) except only four Select elements. I would also like to add the "Reset" button next to "Submit." I know I need to construct a function in my header and use onSubmit attribute within the form but other than that I am unsure of what's involved so I'm hoping someone could point me in the right direction. It's important I learn most of this for myself. Thanks for your time Livingston

  • WinCE and PC USB communication

    - by sebeksd
    We are developing some device and we need to find good solution for one of needed functionality. Thing is that we need communicate WinCE 6.0 (ARM) and Windows on PC. Easiest way is of course COM port but in our case it is impossible (all serial ports are used on WinCE and we don't want to add one more). Second option is LAN but for us it is not the best option for few reasons. So there is third option we could use. USB to USB communication but how to do that ? Of course WinCE is USB Device and PC is USB Host so all hardware basics are meet. We could use Active sync but there are few problems with it: - WinCE 6.0 is not working with WMDC (drivers on device just crash after connecting device with PC) and I didn't find any solution for it so in this case we need to use WinXP on PC side (old ActiveSync) - we need to filter communication with active sync to only our application, no other non authorized software should be allowed (what I know this is imposible to obtain). So propably best way to do what we need is to communicate throug USB like standard COM (serial communication). The question is, how it could be made, are we need to write driver on WinCE and also a Driver on Windows (PC), or there are better solution? Maybe some driver for WinCE 6.0 that would emulate Virtual COM on PC side (and of course allow standard Read/Write to it on WinCE side) ? Could someone tell me if something like that exists ?

  • IE CSS bug: table border showing div with visibility: hidden, position: absolute

    - by Alessandro Vernet
    The issue I have a <div> on a page which is initially hidden with a visibility: hidden; position: absolute. The issue is that if a <div> hidden this way contains a table which uses border-collapse: collapse and has a border set on it cells, that border still shows "through" the hidden <div> on IE. Try this for yourself by running the code below on IE6 or IE7. You should get a white page, but instead you will see: Possible workaround Since this is happening on IE and not on other browsers, I assume that this is an IE bug. One workaround is to add the following code which will override the border: .hide table tr td { border: none; } I am wondering: Is this a known IE bug? Is there a more elegant solution/workaround? The code <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <style type="text/css"> /* Style for tables */ .table tr td { border: 1px solid gray; } .table { border-collapse: collapse; } /* Class used to hide a section */ .hide { visibility: hidden; position: absolute; } </style> </head> <body> <div class="hide"> <table class="table"> <tr> <td>Gaga</td> </tr> </table> </div> </body> </html>

  • Java equivalent of C++ std::map?

    I'm looking for a Java class with the characteristics of C++ std::map's usual implementation (as I understand it, a self-balancing binary search tree): O(log n) performance for insertion/removal/search Each element is composed of a unique key and a mapped value Keys follow a strict weak ordering I'm looking for implementations with open source or design documents; I'll probably end up rolling my own support for primitive keys/values. This question's style is similar to: Java equivalent of std::deque, whose answer was "ArrayDeque from Primitive Collections for Java".
