• Linq to SQL code generator features

  - by Anders Abel

  I'm very fond of Linq to SQL and the programming model it encourages. I think that in many cases when you are in control of both the database schema and the code it is not worth the effort to have different relational and object models for the data. Working with Linq to SQL makes it simple to have type safe data access from .NET, using the partial extension methods to implement business rules. Unfortunately I do not like the dbml designer due to the lack of a schema refresh function. So far I have used SqlMetal, but that lacks the customization options of the dbml designer. Because of that I've started working on a tool which regenerates the whole code file like SqlMetal, but has the ability to do the customizations that are available in the dbml designer (and maybe more in the future). The customizations will be described in an xml file which only contains those parts that shouldn't have default values. This should keep the xml file size down as well as the maintenance burden of it. To help me focus on the right features, I would like to know: What would be your favourite feature in a linq to sql code generator?

• Jquery: how to call the function again?

  - by bakazero

  I'm making the script for easy upload many files. I've tried fyneworks plugin, but the file name does not appear in a form that uses tiny_mce. This is the code: $("document").ready(function () { var i = 0; //iteration for Inputted File var max = 5; //max file uploaded createStatus(); //generate status container $('.imageNow').change(function() { if($(this).val()) { var ext = $(this).val().split('.').pop().toLowerCase(); var allow = [ 'gif', 'png', 'jpg', 'jpeg' ]; if (jQuery.inArray(ext, allow) != -1) { //validation true addImgInput($(this).clone()); $(this).addClass('imgOK'); $(this).removeClass('imageNow'); addImgList($(this).val()); removeImgStatus(); i++; } else { addImgStatus(); $(this).remove(); addImgInput(); } } return false; }); }); This is another function that I use: function addImgInput(inputClone) { $(inputClone).prependTo( $('#upload_images') ); //div container for generated InputFileImg }; function addImgList(listingImg) { $('#list_image_file').append('<li>' + listingImg + '</li>' ); //list all images that have been inputted } function createStatus() { $('#upload_images').append('<small class="status"></small>'); //error display container } function addImgStatus() { $('.status').append('* Wrong File Extension'); //error display text } function removeImgStatus() { $('.status').empty(); } Mmm..yeah is't not finished yet, because when I try to generate another Inputfile with imageNow class, the $('.imageNow').change(function() is not going to work anymore. Does anyone can help me? Thanks

• Using JQuery to traverse DOM structure, finding a specific <table> element located after HTML 'comme

  - by Shadow

  I currently have a website source code (no control over the source) which contains certain content that needs to be manipulated. This would be simple on the surface, however there is no unique ID attribute on the tag in question that can uniquely identify it, and therefore allow for further traversal. Here is a snippet of the source code, surrounding the tag in question. ... <td width="100%"> <!--This table snaps the content columns(one or two)--> <table border="0" width="100%"> ... Essentially, the HTML comment stuck out as an easy way to gain access to that element. Using the JQuery comment add-on from this question, and some help from snowlord comment below, I have been able to identify the comment and retrieve the following output using the 'dump' extension. $('td').comments().filter(":contains('This table snaps the content columns(one or two)')").dump(); returns; jQuery Object { 0 = DOMElement [ nodeName: DIV nodeValue: null innerHTML: [ 0 = String: This table snaps the content columns(one or two) ] ] } However I am not sure how to traverse to the sibling element in the DOM. This should be simple, but I haven't had much selector experience with JQuery. Any suggestions are appreciated.

• Can't write to dynamic iframe using jQuery

  - by Fremont Troll

  My goal is to dynamically create an iframe and write ad JavaScript into it using jQuery (e.g. Google AdSense script). My code works on Chrome, but fails intermittently in Firefox i.e. sometimes the ad script runs and renders the ad, and other times it doesn't. When it doesn't work, the script code itself shows up in the iframe. My guess is these intermittent failures occur because the iframe is not ready by the time I write to it. I have tried various iterations of *iframe_html* (my name for the function which is supposed to wait for the iframe to be ready), but no luck. Any help appreciated! PS: I have read various threads (e.g. http://stackoverflow.com/questions/205087/jquery-ready-in-a-dynamically-inserted-iframe). Just letting everyone know that I've done my research on this, but I'm stuck :) Iteration 1: function iframe_html(html){ $('<iframe name ="myiframe" id="myiframe"/>').appendTo('#maindiv'); $('#myiframe').load( function(){ $('#myiframe').ready( function(){ var d = $("#myiframe")[0].contentWindow.document; d.open(); d.close(); d.write(html); }); } ); }; Iteration 2: function iframe_html(html){ $('<iframe id="myiframe"/>').appendTo('#maindiv').ready( function(){ $("#myiframe").contents().get(0).write(html); } ); };

• How can I differentiate a manual scroll (via mousewheel/scrollbar) from a Javascript/jQuery scroll?

  - by David Murdoch

  UPDATE: Here is a jsbin example demonstrating the problem. Basically, I have the following javascript which scrolls the window to an anchor on the page: // get anchors with href's that start with "#" $("a[href^=#]").live("click", function(){ var target = $($(this).attr("href")); // if the target exists: scroll to it... if(target[0]){ // If the page isn't long enough to scroll to the target's position // we want to scroll as much as we can. This part prevents a sudden // stop when window.scrollTop reaches its maximum. var y = Math.min(target.offset().top, $(document).height() - $(window).height()); // also, don't try to scroll to a negative value... y=Math.max(y,0); // OK, you can scroll now... $("html,body").stop().animate({ "scrollTop": y }, 1000); } return false; }); It works perfectly......until I manually try to scroll the window. When the scrollbar or mousewheel is scrolled I need to stop the current scroll animation...but I'm not sure how to do this. This is probably my starting point... $(window).scroll(e){ if(IsManuallyScrolled(e)){ $("html,body").stop(); } } ...but I'm not sure how to code the IsManuallyScrolled function. I've checked out e (the event object) in Google Chrome's console and AFAIK there is not way to differentiate between a manual scroll and jQuery's animate() scroll. How can I differentiate between a manual scroll and one called via jQuery's $.fn.animate function?

• .htaccess Redirect Loop, adding multiple .php extensions

  - by Ryan Smith

  I have sort of a small parent/teacher social network set up for my school. I use my .htaccess file to make the links to teacher profiles cleaner and to add a trailing slash to all urls. I get this problem when going to /teachers/teacher-name/ the link (sometimes) redirects to /teachers/teacher-name.php.php.php.php.php.php.php.php... Below is my .htaccess file. Sometimes if I clear my browser cache in Chrome it temporarily fixes it. I can't exactly wright .htaccess syntax, but I'm pretty familiar with it. Any suggestions are appreciated! RewriteEngine on RewriteBase / #remove php ext RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^([^/]+)/$ $1.php RewriteRule ^([^/]+)/([^/]+)/$ $1/$2.php #force trailing slash/ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)([^/])$ /$1$2/ [L,R=301] #other rewrites RewriteRule ^teachers/([^/\.]+)/$ /teachers/profile.php?u=$1 RewriteRule ^teachers/([^/\.]+)/posts/$ /teachers/posts.php?u=$1 RewriteRule ^teachers/([^/\.]+)/posts/([^/\.]+)/$ /teachers/post.php?u=$1&p=$2 RewriteRule ^gallery/([^/\.]+)/$ /gallery/album.php?n=$1 RewriteRule ^gallery/([^/\.]+)/slideshow/$ /gallery/slideshow.php?n=$1 RewriteRule ^gallery/([^/\.]+)/([^/\.]+)/([^/\.]+)/$ /gallery/photo.php?a=$1&p=$2&e=$3 EDIT:I have attached a screenshot of exactly what I'm talking about.

• Why this class assignment is not working in IE

  - by user550750

  I've wrote this peice of code, this works fine in FF and Chrome but not in IE. Why is it? <html> <header> <style type="text/css"> .red{ color: red; } .green{ color: green; } .yellow{ color: yellow; } </style> </header> <body> <div id="mydiv" style="height: 50px">Some contents</div> <div> <input type="radio" value="1" name="change" onclick="onClick(this)">Red</input> <input type="radio" value="2" name="change" onclick="onClick(this)">Green</input> <input type="radio" value="3" name="change" onclick="onClick(this)">Yellow</input> </div> <script type="text/javascript"> function onClick(el){ var className = ""; if(el.value == 1){ className = "red"; }else if(el.value == 2){ className = "green"; }else if(el.value == 3){ className = "yellow"; } document.getElementById("mydiv").setAttribute("class", className); } </script> </body> </html>

• Anchor tags are blank

  - by ryanday

  I'm having a problem where the my anchor tags sometimes aren't displaying their links. This is happening on Mobile Safari on multiple iPhones, and in the iPhone simulator. I'm using jQtouch r147, PhoneGap, and jQuery 1.4.2. I'm generating the data from a database call, and adding anchor tags to a list like this: for(var i=0;i<data.rows.length;i++) { var item = $('<li></li>'); var name = data.rows.item(i).name; var anchor = $('<a href="#lpage">'+name+'</a>'); item.addClass('arrow'); // This line always displays the name, even when I can't see // the name in the browser debug.log('The name: ' + name); (function(info) { anchor.bind('tap', function(e) { debug.log('Touch start ' + info.id); }); })(data.rows.item(i)); item.append(anchor); if( anchor.html() == null ) { debug.log('html is blank'); } $('#myUL').append(item); } Sometimes my list of names shows fine(http://imagebin.org/101462), and sometimes it is just blank(http://imagebin.org/101464). When the list is blank, I see the debug.log() line show me 'html is blank', and I also see the log line show me that the variable 'name' does, in fact, contain a valid name. When I check for anchor.html() == null, I've also tried to .remove() the anchor tag, and re-create it. But it always comes back without the name displayed. This happens on the mobile device and in the simulator, but I've never seen it happen in Safari or in Chrome. Has anyone seen something like this? I can't find the cause, and I can't get it to stop. Thank you for any ideas or suggestions!

• Ext JS 4.2.1 loading controller - best practice

  - by Hown_

  I am currently developing a Ext JS application with many views/controlers/... I am wondering myself what the best practice is for loading the JS controllers/views/and so on... currently i have my application defined like this: // enable javascript cache for debugging, otherwise Chrome breakpoints are lost Ext.Loader.setConfig({ disableCaching: false }); Ext.require('Ext.util.History'); Ext.require('app.Sitemap'); Ext.require('app.Error'); Ext.define('app.Application', { name: 'app', extend: 'Ext.app.Application', views: [ // TODO: add views here 'app.view.Viewport', 'app.view.BaseMain', 'app.view.Main', 'app.view.ApplicationHeader', //administration 'app.view.administration.User' ... ], controllers: [ 'app.controller.Viewport', 'app.controller.Main', 'app.controller.ApplicationHeader', //administration 'app.controller.administration.User', ... ], stores: [ // stores in there.. ] }); somehow this forces the client to load all my views and controllers at startup and is calling all init methods of all controllers of course.. i need to load data everytime i chnage my view.. and now i cant load it in my controllers init function. I would have to do something like this i assume: init: function () { this.control({ '#administration_User': { afterrender: this.onAfterRender } }); }, Is there a better way to do this? Or just an other event? Though the main thing i am questioning myself is if it is the best practice to load all the javascript at startup. Wouldnt it be better to only load the controllers/views/... which the client does need right now? Or should i load all the JS at startup? If i do want to load the controllers dynamicly how could i do this? I assume a would have to remove them from my application arrays (views, controllers, stores) and create an instance if i do need it and mby set the view in the controllers init?! What's best practice??

• Iframe/Popup redirecting opener window

  - by Bara

  Hello all, I have a page located at x.com. On this page is a button that, when clicked, will launch a new window (using javascript's window.open() method) to a page that is located at z.com. The popup does a few things, then redirects the original window (the opener, x.com) to a different page based on some parameters defined in the popup. This works fine in Firefox/Chrome, but not in IE. In IE (8 specifically, but I believe 7 also has this problem) the original window (the opener) is not redirected. Instead, a new window comes up and THAT window is redirected. I've tried many different methods to try and get this to work, including changing the popup to an iframe loaded on the page and having a function on the opener that the popup/iframe call. The problem seems to be that IE refuses to allow cross-domain sites to talk to each other via javascript. Is there a way around this? How can I get the parent window to redirect to a page based on parameters in a popup or iframe? Bara

• Have to click twice to submit the form in IE8

  - by phil

  A very peculiar bug in a simple html form. After changing an option, button has to be clicked twice to submit the form. Button is focused after clicking once, but form is not submitted. It's only this way in IE8 and works fine in Chrome and FF. PAY ATTENTION TO 'g^' right before <select>. It has to be a letter or number followed by a symbol to generate this bug. For example, 'a#','f$','3(' all create the same bug. Otherwise it works fine. BTW, if you don't change option and click button right away,there won't be any bug. Very strange, huh? <form method="post" action="match.php"> g^ <select> <option>Select</option> <option>English</option> <option>French</option> </select> <input type="submit" value="Go" /> </form>

• Custom Silverlight Splash Screen causes White Screen of Death

  - by wickster05

  I'm developing a Silverlight 4 application and I've created a custom splash screen. At first glance, the custom splash screen worked well - really well. After a few days I started noticing that the splash screen would no longer show and the screen would remain blank. This seems to only occur when I open multiple IE tabs/windows all pointing to this same application. The first few will load fine, while the following tabs/windows will remain "white" - as if nothing has/is loaded. This doesn't appear to be an issue with other browsers that I've tested with (i.e., Firefox and Chrome). Unfortunately, this product requires multiple screens to be open (and I'm not going to require our users to use a non-Microsoft internet browser). Furthermore, we have another product that hosts this Silverlight application inside a WPF WebBrowser control (which is similar to IE - and experiences the same issues as delineated above). Does anyone have any ideas on how to get around this? This is becoming increasingly frustrating. I should also point out, that the default splash screen seems to avoid these issues. When I remove the custom splash screen, we no longer see these problems. ANY help would be appreciated greatly! -Tom

• Update SQL Server 2000 to SQL Server 2008: Benefits please?

  - by Ciaran Archer

  Hi there I'm looking for the benefits of upgrading from SQL Server 2000 to 2008. I was wondering: What database features can we leverage with 2008 that we can't now? What new TSQL features can we look forward to using? What performance benefits can we expect to see? What else will make management go for it? And the converse: What problems can we expect to encounter? What other problems have people found when migrating? Why fix something that isn't (technically) broken? We work in a Java shop, so any .NET / CLR stuff won't rock our world. We also use Eclipse as our main development so any integration with Visual Studio won't be a plus. We do use SQL Server Management Studio however. Some background: Our main database machine is a 32bit Dell Intel Xeon MP CPU 2.0GHz, 40MB of RAM with Physical Address Extension running Windows Server 2003 Enterprise Edition. We will not be changing our hardware. Our databases in total are under a TB with some having more than 200 tables. But they are busy and during busy times we see 60-80% CPU utilisation. Apart form the fact that SQL Server 2000 is coming close to end of life, why should we upgrade? Any and all contributions are appreciated!

• Overriding content_type for Rails Paperclip plugin

  - by Fotios

  I think I have a bit of a chicken and egg problem. I would like to set the content_type of a file uploaded via Paperclip. The problem is that the default content_type is only based on extension, but I'd like to base it on another module. I seem to be able to set the content_type with the before_post_process class Upload < ActiveRecord::Base has_attached_file :upload before_post_process :foo def foo logger.debug "Changing content_type" #This works self.upload.instance_write(:content_type,"foobar") # This fails because the file does not actually exist yet self.upload.instance_write(:content_type,file_type(self.upload.path) end # Returns the filetype based on file command (assume it works) def file_type(path) return `file -ib '#{path}'`.split(/;/)[0] end end But...I cannot base the content type on the file because Paperclip doesn't write the file until after_create. And I cannot seem to set the content_type after it has been saved or with the after_create callback (even back in the controller) So I would like to know if I can somehow get access to the actual file object (assume there are no processors doing anything to the original file) before it is saved, so that I can run the file_type command on that. Or is there a way to modify the content_type after the objects have been created.

• Can a Generic Method handle both Reference and Nullable Value types?

  - by Adam Lassek

  I have a series of Extension methods to help with null-checking on IDataRecord objects, which I'm currently implementing like this: public static int? GetNullableInt32(this IDataRecord dr, int ordinal) { int? nullInt = null; return dr.IsDBNull(ordinal) ? nullInt : dr.GetInt32(ordinal); } public static int? GetNullableInt32(this IDataRecord dr, string fieldname) { int ordinal = dr.GetOrdinal(fieldname); return dr.GetNullableInt32(ordinal); } and so on, for each type I need to deal with. I'd like to reimplement these as a generic method, partly to reduce redundancy and partly to learn how to write generic methods in general. I've written this: public static Nullable<T> GetNullable<T>(this IDataRecord dr, int ordinal) { Nullable<T> nullValue = null; return dr.IsDBNull(ordinal) ? nullValue : (Nullable<T>) dr.GetValue(ordinal); } which works as long as T is a value type, but if T is a reference type it won't. This method would need to return either a Nullable type if T is a value type, and default(T) otherwise. How would I implement this behavior?

• Applying fine-grained security to an existing application

  - by Mark

  I've inherited a reasonably large and complex ASP.NET MVC3 web application using EF Code First on SQL Server. It uses ASP.NET Membership roles with database authentication. The controller actions are secured with attributes derived from AuthorizeAttribute that map roles to actions. There are extension methods for the finer points, such as showing a particular widget to particular roles. This is works great and I have a good understanding of the current security model. I've been asked to provide finer grained security at the data level. For example a 'Customer' user can only see data (throughout the database) associated with themselves and not other Customers. The problem is that 'Customer' is only 1 of 5 different types with their own specific restrictions (each of the 9 roles is one of these 5 types). The best thing I can think of is to go through all the data repositories and extend each and every LINQ statements/query with a filter for every user type. Even if I had time for that it doesn't seem like the most elegant way. Any suggestions? I really don't know where to start with this so anything could be helpful. Many thanks.

• Unable to turn off notice errors in PHP 5.3.2

  - by knkk

  Hi everyone, I recently migrated to PHP 5.3.2, and realized that I am unable to turn off notice errors in my site now. I went to php.ini, and in these lines: ; Common Values: ; E_ALL & ~E_NOTICE (Show all errors, except for notices and coding standards warnings.) ; E_ALL & ~E_NOTICE | E_STRICT (Show all errors, except for notices) ; E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors) ; E_ALL | E_STRICT (Show all errors, warnings and notices including coding standards.) ; Default Value: E_ALL & ~E_NOTICE ; Development Value: E_ALL | E_STRICT ; Production Value: E_ALL & ~E_DEPRECATED ; http://php.net/error-reporting error_reporting = E_ALL & ~E_NOTICE ...I've tried setting everything (and I restart apache each time), but I am unable to get rid of notices. The only way I'm able to get rid of notice errors is by setting : display_errors = Off That is, of course, not something I can do since I need to see errors to fix them, and I would like to see errors on the webpage that I am coding rather than log them somewhere. Can someone help? Is this a bug in PHP 5.3.2 or something I am doing wrong? Thank you very much for your time! P. S. Also, would anyone know how I can get PHP 5.3.2 to support the .php3 extension?

• How to efficiently compare the sign of two floating-point values while handling negative zeros

  - by François Beaune

  Given two floating-point numbers, I'm looking for an efficient way to check if they have the same sign, given that if any of the two values is zero (+0.0 or -0.0), they should be considered to have the same sign. For instance, SameSign(1.0, 2.0) should return true SameSign(-1.0, -2.0) should return true SameSign(-1.0, 2.0) should return false SameSign(0.0, 1.0) should return true SameSign(0.0, -1.0) should return true SameSign(-0.0, 1.0) should return true SameSign(-0.0, -1.0) should return true A naive but correct implementation of SameSign in C++ would be: bool SameSign(float a, float b) { if (fabs(a) == 0.0f || fabs(b) == 0.0f) return true; return (a >= 0.0f) == (b >= 0.0f); } Assuming the IEEE floating-point model, here's a variant of SameSign that compiles to branchless code (at least with with Visual C++ 2008): bool SameSign(float a, float b) { int ia = binary_cast<int>(a); int ib = binary_cast<int>(b); int az = (ia & 0x7FFFFFFF) == 0; int bz = (ib & 0x7FFFFFFF) == 0; int ab = (ia ^ ib) >= 0; return (az | bz | ab) != 0; } with binary_cast defined as follow: template <typename Target, typename Source> inline Target binary_cast(Source s) { union { Source m_source; Target m_target; } u; u.m_source = s; return u.m_target; } I'm looking for two things: A faster, more efficient implementation of SameSign, using bit tricks, FPU tricks or even SSE intrinsics. An efficient extension of SameSign to three values.

• How do i make divs go into another row when full?

  - by acidzombie24

  My code is something like the below. When theres 3 images everything is fine once theres 4 it gets full and moves the entire div.top into another row. How do i make the div inside top just start a new row instead? I tried writing .top width=500px but once it hits or passes it instead the images inside are squeeze together instead of each being 150x150. I tried max-width on top instead and in opera and chrome i see the border of top as 500width but the images continue to render pass it. (i have a firefox problem with my div so the width looks fixed to something else). So how do i make these divs go into another row? and not try to squeeze together <div class="top"> <div><a href><img/></a></div> <div><a href><img/></a></div> <div><a href><img/></a></div> </div>

• Still don't understand file upload-folder permissions

  - by Camran

  I have checked out articles and tutorials. I don't know what to do about the security of my picture upload-folder. It is pictures for classifieds which should be uploaded to the folder. This is what I want: Anybody may upload images to the folder. The images will be moved to another folder, by another php-code later on (automatic). Only I may manually remove them, as well as another php file on the server which automatically empties the folder after x-days. What should I do here? The images are uploaded via a php-upload script. This script checks to see if the extension of the file is actually a valid image-file. When I try this: chmod 755 images the images wont be uploaded. But like this it works: chmod 777 images But 777 is a security risk right? Please give me detailed information... The Q is, what to do to solve this problem, not info about what permissions there are etc etc... Thanks If you need more info let me know...

• Java: extending Object class

  - by Fabio F.

  Hello, I'm writing (well, completing) an "extension" of Java which will help role programming. I translate my code to Java code with javacc. My compilers add to every declared class some code. Here's an example to be clearer: MyClass extends String implements ObjectWithRoles { //implements... is added /*Added by me */ public setRole(...){...} public ... /*Ends of stuff added*/ ...//myClass stuff } It adds Implements.. and the necessary methods to EVERY SINGLE CLASS you declare. Quite rough, isnt'it? It will be better if I write my methods in one class and all class extends that.. but.. if class already extends another class (just like the example)? I don't want to create a sort of wrapper that manage roles because i don't want that the programmer has to know much more than Java, few new reserved words and their use. My idea was to extends java.lang.Object.. but you can't. (right?) Other ideas? I'm new here, but I follow this site so thank you for reading and all the answers you give! (I apologize for english, I'm italian)

• Is hardware accelerated CSS3 in Safari 4 & 5 broken, or my CSS and JS?

  - by Dan Forys

  Hi all, I've created a somewhat silly site that shows you the expected weather forecast for any city in the World. On webkit based browsers, when the weather is sunny a sun with CSS3 animated rotated sunbeams appears. This works fine on Chrome. An example (sunny, at the moment) page is: http://willitraintoday.co.uk/iceland/reykjavik/ However, when viewed in Safari 4 or 5 on Mac Snow Leopard, when the sun appears the sky background appears over it. Weirder still, as the cloud containing the advert moves across the sky, it squashes the main text. When the cloud reaches the left edge, the text appears wider than normal and starts squashing down again. I've tried: - Disabling the CSS3 animation; it works fine in Safari - Juggling the z-index of various elements; to no avail Is there something up with my Javascript or CSS, or is the hardware accelerated snow leopard Safari broken in this case? It seems not to happen in Safari 4 on Leopard, but I don't have Leopard any more to test myself. Grateful for any opinions!
