• Centering images php

  - by peak

  I'm trying to center an image in php. I'm currently using this line of code echo '<img src="newimage.jpg" width="110" height="120" class="centre">'; However, this seems to have no effect. I've also tried using something like this, img.center { display: block; margin-left: auto; margin-right: auto; } <img src="newimage.jpg" alt="Suni" class="center" /> but this merely gives me a syntax error, how do I go about fixing this? Thanks

• Jquery/CSS help needed to make fallback for IE and older browsers

  - by matt_50

  Wondering if any of you can help me: I've made a signup modal that uses a CSS transform to switch between two methods of signing up. I've decided to try a 'card flip' type effect. Have a look at this JSfiddle in any browser that supports CSS 3D transforms - click the 'old fashioned way' text to 'flip' the modal (simplified for demo purposes): http://jsfiddle.net/voodoo6/cnTMz/8/ Then take a look in IE8/9 - as the 'back' is taller than the front and IE does;t support 'backface-visibility: hidden;' the reverse can be seen below the front. I've been trying to use JQuery and conditional CSS to 'display:none' the 'back' on load in IE (and older browsers), then add a 'display:block;' class to show it on click, problem is, I'm a JQuery beginner and have been struggling to get it to work! Not even sure if this is the best approach? Can anybody suggest an approach that would get this working in less-capable browsers? Thanks for any advice..

• Subsonic: Select on a View, locks the table update?

  - by Jay

  Hi, I have a Web site live and running now. I am using the Subsonic to handle the database connections etc. I am getting time out expired error while updating a table (say Employee). When I check sp_who2, I see the suspended connection for the PID which is updating with a block by anothor pid, so I run the profiler and found out when ever this suspended connection occur, the blocked pid is a select statement on the view (say ActiveEmployees, which is the same as the table but with some where conditions). Anyone know why a Select statement on the view could cause failure in update. If it is other (like select fails due to update) may be reasonable. Is there any way for me to make select on a view without locking the table? PS: I am using the Sql server 2005 and subsonic 2.2. Thanks

• Three boolean values saved in one tinyint

  - by Casper

  Hello, probably a simple question but I seem to be suffering from programmer's block. :) I have three boolean values: A, B, and C. I would like to save the state combination as an unsigned tinyint (max 255) into a database and be able to derive the states from the saved integer. Even though there are only a limited number of combinations, I would like to avoid hard-coding each state combination to a specific value (something like if A=true and B=true has the value 1). I tried to assign values to the variables so (A=1, B=2, C=3) and then adding, but I can't differentiate between A and B being true from i.e. only C being true. I am stumped but pretty sure that it is possible. Thanks

• Dynamically generate Triangle Lists for a Complex 3D Mesh

  - by Vulcan Eager

  In my application, I have the shape and dimensions of a complex 3D solid (say a Cylinder Block) taken from user input. I need to construct vertex and index buffers for it. Since the dimensions are taken from user input, I cannot user Blender or 3D Max to manually create my model. What is the textbook method to dynamically generate such a mesh? Edit: I am looking for something that will generate the triangles given the vertices, edges and holes. Something like TetGen. As for TetGen itself, I have no way of excluding the triangles which fall on the interior of the solid/mesh.

• lexers / parsers for (un) structured text documents

  - by wilson32

  There are lots of parsers and lexers for scripts (i.e. structured computer languages). But I'm looking for one which can break a (almost) non-structured text document into larger sections e.g. chapters, paragraphs, etc. It's relatively easy for a person to identify them: where the Table of Contents, acknowledgements, or where the main body starts and it is possible to build rule based systems to identify some of these (such as paragraphs). I don't expect it to be perfect, but does any one know of such a broad 'block based' lexer / parser? Or could you point me in the direction of literature which may help?

• Application_EndRequest Dosent Fire on a 404

  - by Shane

  I am using ASP MVC 2 and Nhibernate. I have created an HTTP Module as demonstrated in Summer of NHibernate 13 that looks like so: public void Init(HttpApplication context) { context.PreRequestHandlerExecute += new EventHandler(Application_BeginRequest); context.PostRequestHandlerExecute += new EventHandler(Application_EndRequest); } private void Application_BeginRequest(object sender, EventArgs e) { ISession session = StaticSessionManager.OpenSession(); session.BeginTransaction(); CurrentSessionContext.Bind(session); } private void Application_EndRequest(object sender, EventArgs e) { ISession session = CurrentSessionContext.Unbind(StaticSessionManager.SessionFactory); if (session != null) try { session.Transaction.Commit(); } catch (Exception) { session.Transaction.Rollback(); } finally { session.Flush(); session.Close(); } } web.config <add name="UnitOfWork" type="HttpModules.UnitOfWork"/> My problem is that Application_EndRequest never gets called on a 404 error so if my view does not render I completely block database access until my flush takes place. I am fairly new to NHibernate so I am not sure if I am missing something.

This is what I have found .theme-default .nivo-controlNav.nivo-thumbs-enabled img { display: block; height: auto; width: auto; } Any help or advice is appreciated.

• Best practices: displaying text that was input via multi-line text box

  - by chris

  I have a multi-line text box. When users simply type away, the text box wraps the text, and it's saved as a single line. It's also possible that users may enter line breaks, for example when entering a "bulleted" lists like: Here are some suggestions: - fix this - remove that - and another thing Now, the problem occurs when I try to display the value of this field. In order to preserve the formatting, I currently wrap the presentation in <pre> - this works to preserve user-supplied breaks, but when there's a lot of text saved as a single line, it displays the whole text block as single line, resulting in horizontal scrolling being needed to see everything. Is there a graceful way to handle both of these cases?

• RSpec: in-depth differences between before(:all) and before(:each)

  - by gmile

  Ok, so I've ran into a very strange issue, directly connected with before blocks. I'm doing a integration testing via Watir and RSpec. For a simple test to check if user can perform a login I'm creating a 'user' record in the db by means of factory_girl. So I put the following code: before(:each) do @user = Factory(:user) end if "should perform a login" do # do stuff end In do stuff I call a browser and see how the user tries to login. Unfortunately, somehow he cannot do that — "Username isn't valid". After some investigation I discovered that if I put the code for creating user in before(:all) block, everything magically works. How's that? What's the difference between :all and :each in this context? Also, If I put the code for creating user actually in the test body, it still doesn't work (i.e. user somehow isn't added to the DB or something).

• How to avoid recursion in Java SecurityManager checkConnect?

  - by Zilupe

  I'm trying to take control of a Java code base that does lots of un-documented things. I'm using a custom SecurityManager to check permission requests. Specifically, my code is checking SocketPermission checks -- checkConnect. checkConnect is called when the application tries to resolve a host name to IP address and to connect to a specific IP address. The problem is that I don't know how to properly call host name resolution (InetAddress.getAddressByName) without falling into infinite recursion, because normally checkConnect is called even when I resolve the name from inside the SecurityManager.checkConnect. I have read on the web that I have to call the address resolution from a doPrivileged block, but no idea how. P.S. Is this possible without writing any policy files?

• h3 tag text/image replacement, does this hurt seo?

  - by Mike007

  I'm trying to "replace" text with an image in all of my h3 tags. I want the image to be in the html to avoid multiple h3 classes as this is being done for a portfolio and there will be about 10 h3 tags on the page. My question is, will this be viewed as an attempt to hide, stuff keywords by google for seo purposes? If it will then does anyone know a better way to accomplish this? CSS: h3 { display: block; width: 156px; height: 44px; overflow: hidden; } Html: <h3><img src="images/project001.png" alt="Recent Projects" />Recent Projects</h3>

• IE display problem

  - by bah

  Hi, I have a page, and I just added pagination to it, but there's a prob in IE 7 & 8. When I add pagination code echo "<div class='pagination'>"; echo $pagination->GetPageLinks(); echo "</div>"; it breaks somehow layout in IE, I have looked all over it and I couldn't find what's wrong there. oh, and its css div.pagination { text-align : center; } div.pagination a, div.pagination span { padding : 5px; display : inline-block; } page url - adelija.puslapiai.lt, it's on index page, if you could take a look, that'd be great.

• Determining if an offset is in between line numbers?

  - by Sophomore

  hi I need to determine if a given selection is in between a start line and an end line. I have an ILineRange and a given offset within the viewport of eclipse. (I need to know, if the selection (from a remote party) was made within the current viewport of the local user. Unfortunately, I cannot get an LineRange from the selection. I must rely on getOffset() and getLength()... Anyone has an idea? I think there is not a clean solution for this, as the offset (or the characters per line vary (new line lines or a big block of comment).

• When is it a good idea to use the CSS display property?

  - by allyourcode

  I think I first learned of this property when I thought "I should put this list of items in a ul, but I want it to be laid out horizontally. I wonder if I can do that with CSS?" When I googled this, I found a couple of sites suggesting that I create a CSS rule that would change the value of the display property of the li elements to inline. I've also seen the suggestion that a div (or other block element) be given display: table-cell in order to force the vertical align property to work. These techniques seem kind of hacky. Does that make sense? This might not be a good analogy, but it seems like trying to ride a car as if it were a motorcycle. Yeah, I could replace the steering wheel with handle bars, wear a helmet, and remove all the passenger seating, but how the heck is a car going to drive on two wheels??

• Setting location based on previous parameter of $routeChangeError with AngularJS

  - by Moo

  I'm listening on events of the type $routeChangeError in a run block of my application. $rootScope.$on("$routeChangeError", function (event, current, previous, rejection) { if (!!previous) { console.log(previous); $location.path(previous.$$route.originalPath); } }); With the help of the previous parameter I would like to set the location to the previous page. This works as long as the "originalPath" of "previous.$$route" does not contain any parameters. If it contains parameters the "originalPath" is not transformed. Logging the previous objects returns the following output: $$route: Object ... originalPath: "/users/:id" regexp: /^\/users\/(?:([^\/]+)?)$/ ... params: Object id: "3" How can I set the location to the previous path including the parameters?

• How to create custom CSS "on the fly" based on account settings in a Django site?

  - by sdolan

  So I'm writing a Django based website that allows users select a color scheme through an administration interface. I already have middleware/context processors that links the current request (based on domain) to the account. My question is how to dynamically serve the CSS with the account's custom color scheme. I see two options: Add a CSS block to the base template that overrides the styles w/variables passed in through a context processors. Use a custom URL (e.g. "/static/dynamic/css//styles.css") that gets routed to a view that grabs all the necessary values and creates the css file. I'm content with either option, but was wondering if anyone else out there has dealt with similar problems and could give some insight as to "Best Practices".

• How do I stop a jquery animation based on CSS values?

  - by kevn

  So, I have two divs: #div1 and #div2. I want '#div2' to disappear when '#div1' has the CSS value: top = 0px. Here is the CSS: #div1 { top: 0px; } #div2 { display: block; } if ( $('#div1').css('top') == '0px' ) { $("#div2").hide(); } else { $("div2").fadeIn(); } $("div2").click(function(){ $("#div1").animate({top:"+=315px"}, "slow"); }); The problem I am running into is that I'm changing that CSS value (for #div1) via Javascript and for this reason, my js doesn't acknowledge the change and doesn't make the div disappear (I think). Is there any way to make #div2 disappear when #div1's CSS property top = 0 and reappear whenever it is changed? Or is there a better way to implement this?
