  • HTML/CSS - How can I position these nested unordered lists correctly?

    - by Samuroid
    I am looking for some help resolving an issue im having with positioning the following unordered list elements that are contained in a div which has relative positioning: The html structure of the UL: <div id="accountBox" class="account_settings_box"> <ul> <ul> <li class="profileImage"><img src="images/profileimage.jpg" alt="Profile Image" /></li> <li class="profileName">Your name</li> <li class="profileEmail">Your email</li> </ul> <li><a href="">Messages</a></li> <li><a href="">Settings</a></li> <li><a href="">Password</a></li> <li><a href="">Sign out</a></li> </ul> </div> and the CSS for this list: .account_settings_box ul ul { display: inline-block; margin: 0; padding: 0; width: 100%; height: 150px; outline: 1px solid blue; } .account_settings_box ul ul li { display: inline-block; border: none; /* Reset the border */ } .profileImage { float: right; display: block; width: 150px; height: 150px; outline: 1px solid purple; } .profileName, .profileEmail { width: auto; height: auto; width: 150px; height: 150px; } .account_settings_box ul ul li:hover { outline: 1px solid red; } .profileImage img { width: 150px; height: 150px; } I am having difficultly with the embedded ul, i.e, .account_settings_box ul ul element. The image below shows what it currently looks like. I am trying to achieve the follow: Have the image floating to the right, and have the "your name" and "your email" positioned to the left of the image (basically where they are currently). Thanks for your help in advance. Sam :)

  • Django conditional template inheritance

    - by Ed
    I have template that displays object elements with hyperlinks to other parts of my site. I have another function that displays past versions of the same object. In this display, I don't want the hyperlinks. I'm under the assumption that I can't dynamically switch off the hyperlinks, so I've included both versions in the same template. I use an if statement to either display the hyperlinked version or the plain text version. I prefer to keep them in the same template because if I need to change the format of one, it will be easy to apply it to the other right there. The template extends framework.html. Framework has a breadcrumb system and it extends base.html. Base has a simple top menu system. So here's my dilemma. When viewing the standard hyperlink data, I want to see the top menu and the breadcrumbs. But when viewing the past version plain text data, I only want the data, no menu, no breadcrumbs. I'm unsure if this is possible given my current design. I tried having framework inherit the primary template so that I could choose to call either framework (and display the breadcrumbs), or the template itself, thus skipping the breadcrumbs, but I want framework.html available for other templates as well. If framework.html extends a specific template, I lose the ability to display it in other templates. I tried writing an if statement that would display a the top_menu block and the nav_menu block from base.html and framework.html respectively. This would overwrite their blocks and allow me to turn off those elements conditional on the if. Unfortunately, it doesn't appear to be conditional; if the block elements are in the template at all, surrounded by an if or not, I lose the menus. I thought about using {% include %} to pick up the breadcrumbs and a split out top menu. In that case though, I'll have to include it all the time. No more inheritance. Is this the best option given my requirement?

  • Plone with Apache Proxy

    - by churnd
    I have a plone zinstance set up through Apache Proxy on OS X Server 10.5. The server is set up with a single vhost on port 80, with Proxy & Proxypass directives to the Plone zinstance: ProxyPass / http://localhost:8080/VirtualHostBase/http/server:80/Plone/VirtualHostRoot/ ProxyPassReverse / http://localhost:8080/VirtualHostBase/http/server:80/Plone/VirtualHostRoot/ However, I have some static HTML and PHP content that I want to display in an iframe via the plone site. I'm thinking I'll need to set up another vhost on a different port, then just specify the port # inline?

  • Getting results in a result set from dynamic SQL in Oracle

    - by msorens
    This question is similar to a couple others I have found on StackOverflow, but the differences are signficant enough to me to warrant a new question, so here it is: I want to obtain a result set from dynamic SQL in Oracle and then display it as a result set in a SqlDeveloper-like tool, just as if I had executed the dynamic SQL statement directly. This is straightforward in SQL Server, so to be concrete, here is an example from SQL Server that returns a result set in SQL Server Management Studio or Query Explorer: EXEC sp_executesql N'select * from countries' Or more properly: DECLARE @stmt nvarchar(100) SET @stmt = N'select * from countries' EXEC sp_executesql @stmt The question "How to return a resultset / cursor from a Oracle PL/SQL anonymous block that executes Dynamic SQL?" addresses the first half of the problem--executing dynamic SQL into a cursor. The question "How to make Oracle procedure return result sets" provides a similar answer. Web search has revealed many variations of the same theme, all addressing just the first half of my question. I found this post explaining how to do it in SqlDeveloper, but that uses a bit of functionality of SqlDeveloper. I am actually using a custom query tool so I need the solution to be self-contained in the SQL code. This custom query tool similarly does not have the capability to show output of print (dbms_output.put_line) statements; it only displays result sets. Here is yet one more possible avenue using 'execute immediate...bulk collect', but this example again renders the results with a loop of dbms_output.put_line statements. This link attempts to address the topic but the question never quite got answered there either. Assuming this is possible, I will add one more condition: I would like to do this without having to define a function or procedure (due to limited DB permissions). That is, I would like to execute a self-contained PL/SQL block containing dynamic SQL and return a result set in SqlDeveloper or a similar tool. So to summarize: I want to execute an arbitrary SQL statement (hence dynamic SQL). The platform is Oracle. The solution must be a PL/SQL block with no procedures or functions. The output must be generated as a canonical result set; no print statements. The output must render as a result set in SqlDeveloper without using any SqlDeveloper special functionality. Any suggestions?

  • Android - making a layout like Entourage/Outlook calendar

    - by teepusink
    Hi, I'm trying to build a layout / view like the Entourage/Outlook calendar view, where when I schedule a time block, a new view will popup overlaying the time block. Something like this one except it's daily and not monthly like in the image http://images.appleinsider.com/office-2008-entourage-10.png What is the best way to implement that? Right now I'm using TableLayout to create the time on the 1st column and supposedly overlay to schedule made on the 2nd column. However, things got very messy especially when the minutes go to 15 minutes and there are overlapping schdule. Wonder if using other layout might work better? Thanks, Tee

  • Help needed with AES between Java and Objective-C (iPhone)....

    - by Simon Lee
    I am encrypting a string in objective-c and also encrypting the same string in Java using AES and am seeing some strange issues. The first part of the result matches up to a certain point but then it is different, hence when i go to decode the result from Java onto the iPhone it cant decrypt it. I am using a source string of "Now then and what is this nonsense all about. Do you know?" Using a key of "1234567890123456" The objective-c code to encrypt is the following: NOTE: it is a NSData category so assume that the method is called on an NSData object so 'self' contains the byte data to encrypt. - (NSData *)AESEncryptWithKey:(NSString *)key { char keyPtr[kCCKeySizeAES128+1]; // room for terminator (unused) bzero(keyPtr, sizeof(keyPtr)); // fill with zeroes (for padding) // fetch key data [key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF8StringEncoding]; NSUInteger dataLength = [self length]; //See the doc: For block ciphers, the output size will always be less than or //equal to the input size plus the size of one block. //That's why we need to add the size of one block here size_t bufferSize = dataLength + kCCBlockSizeAES128; void *buffer = malloc(bufferSize); size_t numBytesEncrypted = 0; CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionPKCS7Padding, keyPtr, kCCKeySizeAES128, NULL /* initialization vector (optional) */, [self bytes], dataLength, /* input */ buffer, bufferSize, /* output */ &numBytesEncrypted); if (cryptStatus == kCCSuccess) { //the returned NSData takes ownership of the buffer and will free it on deallocation return [NSData dataWithBytesNoCopy:buffer length:numBytesEncrypted]; } free(buffer); //free the buffer; return nil; } And the java encryption code is... public byte[] encryptData(byte[] data, String key) { byte[] encrypted = null; Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); byte[] keyBytes = key.getBytes(); SecretKeySpec keySpec = new SecretKeySpec(keyBytes, "AES"); try { Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC"); cipher.init(Cipher.ENCRYPT_MODE, keySpec); encrypted = new byte[cipher.getOutputSize(data.length)]; int ctLength = cipher.update(data, 0, data.length, encrypted, 0); ctLength += cipher.doFinal(encrypted, ctLength); } catch (Exception e) { logger.log(Level.SEVERE, e.getMessage()); } finally { return encrypted; } } The hex output of the objective-c code is - 7a68ea36 8288c73d f7c45d8d 22432577 9693920a 4fae38b2 2e4bdcef 9aeb8afe 69394f3e 1eb62fa7 74da2b5c 8d7b3c89 a295d306 f1f90349 6899ac34 63a6efa0 and the java output is - 7a68ea36 8288c73d f7c45d8d 22432577 e66b32f9 772b6679 d7c0cb69 037b8740 883f8211 748229f4 723984beb 50b5aea1 f17594c9 fad2d05e e0926805 572156d As you can see everything is fine up to - 7a68ea36 8288c73d f7c45d8d 22432577 I am guessing I have some of the settings different but can't work out what, I tried changing between ECB and CBC on the java side and it had no effect. Can anyone help!? please....

  • Tomcat JNDI Connection Pool docs - Random Connection Closed Exceptions

    - by Andy Faibishenko
    I found this in the Tomcat documentation here What I don't understand is why they close all the JDBC objects twice - once in the try{} block and once in the finally{} block. Why not just close them once in the finally{} clause? This is the relevant docs: Random Connection Closed Exceptions These can occur when one request gets a db connection from the connection pool and closes it twice. When using a connection pool, closing the connection just returns it to the pool for reuse by another request, it doesn't close the connection. And Tomcat uses multiple threads to handle concurrent requests. Here is an example of the sequence of events which could cause this error in Tomcat: Request 1 running in Thread 1 gets a db connection. Request 1 closes the db connection. The JVM switches the running thread to Thread 2 Request 2 running in Thread 2 gets a db connection (the same db connection just closed by Request 1). The JVM switches the running thread back to Thread 1 Request 1 closes the db connection a second time in a finally block. The JVM switches the running thread back to Thread 2 Request 2 Thread 2 tries to use the db connection but fails because Request 1 closed it. Here is an example of properly written code to use a db connection obtained from a connection pool: Connection conn = null; Statement stmt = null; // Or PreparedStatement if needed ResultSet rs = null; try { conn = ... get connection from connection pool ... stmt = conn.createStatement("select ..."); rs = stmt.executeQuery(); ... iterate through the result set ... rs.close(); rs = null; stmt.close(); stmt = null; conn.close(); // Return to connection pool conn = null; // Make sure we don't close it twice } catch (SQLException e) { ... deal with errors ... } finally { // Always make sure result sets and statements are closed, // and the connection is returned to the pool if (rs != null) { try { rs.close(); } catch (SQLException e) { ; } rs = null; } if (stmt != null) { try { stmt.close(); } catch (SQLException e) { ; } stmt = null; } if (conn != null) { try { conn.close(); } catch (SQLException e) { ; } conn = null; } }

  • Calculating string sizes on iPhone on a background thread

    - by jbrennan
    I've got some somewhat hefty string size calculations happening in my app (each one takes close to 500ms, and happens when the user scrolls to a new "page" in my app (like the Weather app). The delay only happens once per page, as the calculation only needs to be run once (and can even be cached for subsequent launches with the same data). Anyway, I still like to not block the UI for this type of work, as to me it screams using threads, but I know UIKit is not meant to be used from other threads. (I know NSString is not part of UIKit, but the string sizing methods are part of the UIKitAdditions...) So how should I go about doing this? What's the best way to not block the UI and do so safely?

  • In Ruby are there any related applications of the syntax: class << self ... end

    - by pez_dispenser
    class << self attr_accessor :n, :totalX, :totalY end The syntax above is used for defining class instance variables. But when I think about what syntax implies, it doesn't make any sense to me, so I'm wondering if this type of syntax is used for any other types of definitions. My point of confusion here is this: class << self The append operator normally means "add what's on the right to the object on the left". But in the context of this block, how does that add up to "put the contents of this block into the definition of the class instance rather than the instance"? For the same reason I'm confused as to why in one context class << self can define class instance variables while in another it seems to create class variables such as here: class Point # Instance methods go here class << self # Class methods go here end end

  • F# pattern matching

    - by Roger Alsing
    What would be the most effective way to express the following code? match cond.EvalBool() with | true -> match body.Eval() with | :? ControlFlowModifier as e -> match e with | Break(scope) -> e :> obj //Break is a DU element of ControlFlowModifier | _ -> next() //other members of CFM should call next() | _ -> next() | false -> null cond.EvalBool returns a boolean result where false should return null and true should either run the entire block again (its wrapped in a func called next) or if the special value of break is found, then the loop should exit and return the break value. Is there any way to compress that block of code to something smaller?

    Prompt how to solve a problem, please. There is a block with the text of the unknown sizes. It is necessary to spin (with pouring inside) round this block that the text was in a circle (without dependence from the sizes of the text). At change of the sizes of the text (at window compression) the circle should vary dynamically. It is necessary to make it in browser. From what to me to start to solve the given problem? Can be methods javascript (on a site it is connected jQuery)? P.S. The decision should be ???????????????.

  • Delphi OLE - How to avoid errors like "The requested member of the collection does not exist"?

    - by Edwin
    Hi, I'm automating Word with Delphi, but some times I got an error message: The requested member of the collection does not exist It seems that the Item member of the Styles collection class does not always exist and some times causes the above mentioned error. My workaround is to catch the exception and skip it, but is there anyway to detect it instead of using the try...except block? The problem with the try...except block is that when debugging the raised exception is annoying... My code example: var aWordDoc: _WordDocument i: Integer; ovI: OleVariant; wordStyle: Style; begin for i := 1 to aWordDoc.Styles.Count do begin ovI := i; try wordStyle := aWordDoc.Styles.Item(ovI); except Continue;//skip if any error occurred. end; //do something with wordStyle end; end

  • HTML/CSS set div to height of sibling

    - by Paul
    I have 2 div's contained in a third. One of the contained div's is floated left, the other floated right. I would like the 2 sibling div's to always be at the same height, but am having a problem with this. So far I am only viewing the page in Firefox, and figured I'd worry about any cross-browser issues after I get it working in at least one browser. Here is the markup: <div id="main-container" class="border clearfix"> <div id="left-div" class="border"> ... </div> <div id="right-div" class="border"> ... </div> </div> Here is the CSS: #main-container { position: relative; min-height: 500px; } #left-div { position: relative; float: left; width: 700px; min-height: inherit; } #right-div { position: relative; float: right; width: 248px; min-height: inherit; height: inherit; } .clearfix:after { content: " "; display: block; height: 0; clear: both; visibility: hidden; } .clearfix { display: inline-block; _height: 1%; clear: both; } .clearfix { display: block; clear: both; } .border { border: solid 1px #000; } If the content in the #left-div is longer than 500px, the #right-div does not expand to match. In an example I tried, Firefox said the computed style height of the #main-container was 804px, the computed style height of the #left-div was 800px, and the computed style height of the #right-div was 586.2px, as it had expanded to fit it's own content. I understand I might be going about this the wrong way, and if this is a duplicate questions then I apologize, but I wasn't quite sure what to search under.

  • using MEF with NHibernate and windsor

    - by Fran
    I have an ASP.net MVC application that is using NHibernate under the covers for data access. I'm using the Windsor container to handle injecting ISession references into each controller. This works great, but now I'm looking to expand my application with a pluggable architecture so that I can have a core product and specific add-ons. I found a great article on doing this with MEF. My question is how to make the Windsor container and MEF container, life/work together so that I can achieve this. There was an article (http://codebetter.com/blogs/glenn.block/archive/2009/10/31/should-i-use-mef-with-an-ioc-container.aspx) by Glenn Block that talked about this exact issue. Then end then said that the next article would show you how to do this, but there's no part 2. Has anyone created an application like this using asp.net mvc, mef, nhibernate, castle windsor?

  • HTML overlay height to cover entire visible page

    - by Evgeny
    I have a web page that loads some stuff using AJAX. I want to display an overlay with a loading indicator while the loading is in progress, so that the user cannot interact with most of the page - except the menu at the top. I'm using jQuery and the jQuery BlockUI plugin to do this. I call $(element).block() and it works fine, but the overlay only extends as far down as the current content of my page. As more content is loaded and added to the page the overlay moves down with it and this looks a bit ugly. Ideally I'd like it to cover the entire visible area of the page right from the start. A simple hack for doing this would be to set a large height value for the overlay, like this: $(myElement).block({ overlayCSS: { height: '10000px' } }); ... but this creates a scrollbar! How do I avoid this and make it just the right height to cover the visible page, but not enlarge it?

  • Attachment_fu error

    - by cswebgrl
    Hello, I am getting an error while trying to upload images on an Ubuntu machine that's running Rails 2.3.4, Ruby 1.8.6 using attachment_fu with image science. FreeImage exception for type ???: IPTC: Invalid key 'Tag 0x025C' The error seems to point to this line in the image_science_processor in the attachment_fu plugin: def with_image(file, &block) ::ImageScience.with_image file, &block end My initial thoughts are that it has something to do with meta tags and the images and maybe free image. I don't actually see this error on my dev machine - Mac Snow Leopard, Rails 2.3.5, Ruby 1.8.7. Before I start messing versions on the production boxes, has anyone else encountered this issue and have an idea to fix it? THANKS!!!!

  • TIBRV: Remote vs Local RVD

    - by jsw
    When connected to a local RVD a sending application is shielded from network interruptions and the send message methods will only block for the time it takes for the message to reach the local RVD process. With remote RVD the sending application is no longer shielded from network interruptions and the send message methods will block for the time it takes to hop across the network to reach the remote RVD process. Is my understanding correct? The documentation is vague regarding remote daemons. I'm mostly concerned with how reliable and performant the send message will be from the perspective of a sending application. Introducing unnecessary blocking on the client side due to sending a message (especially a network hop) is a big no-no in this application. The speed at which the messages reach the consumer is not of the utmost importance. With this in mind is a remote RVD out of the question?

I work on a website where almost all objects are in a jCarousel element : <div> <ul id="mycarousel"> <li>object 1</li> <li>object 2</li> </ul> </div> is the "written" code, and : <div class=" jcarousel-skin-tango"> <div class="jcarousel-container jcarousel-container-horizontal" style="display: block;"> <div class="jcarousel-prev jcarousel-prev-horizontal jcarousel-prev-disabled jcarousel-prev-disabled-horizontal" style="display: block;" disabled="true"></div> <div class="jcarousel-next jcarousel-next-horizontal" style="display: block;" disabled="false"></div> <div class="jcarousel-clip jcarousel-clip-horizontal"> <ul class=" jcarousel-list jcarousel-list-horizontal" id="mycarousel" style="width: 2853px; left: 0px;"> <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-1 jcarousel-item-1-horizontal" jcarouselindex="1" style="width: 307px;"> object 1 </li> <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-1 jcarousel-item-1-horizontal" jcarouselindex="1" style="width: 307px;"> object 2 </li> </ul> </div> </div> is the generated code (here it lacks the ultimate </div>, maybe a number of rows limitation ?). I'm sorry I can't provide a link, I work on a local server currently. It works perfectly =) but... my problem is : an <input type="text" /> won't be clickable in this environment. I tried the others type of input, radio, checkbox, file : works. But text does not. I can specify a value on my input (it's its purpose on my work : a search in a database for datas to be modified and reinjected in database). In fact, I can access to the text input by clicking-right in then left. But it's pretty 'unergonomic', and in my project it's unthinkable. Ah, and I tried to style this input with a style="z-index:1000;", no changes, I think it's not a CSS problem. Does anybody have an idea ? Thank you very much in advance.

  • validation in javascript - remove the error msg on focus

    - by fusion
    i'm not very well-versed with javascript, so please bear with me. i've a form in which i validate the controls with javascript. the error is displayed when the fields are empty via a div, but when i focus and type something in the textbox, the div should go away. but the error div doesn't and even if i type something valid, it still displays the div. i'd like to know where am i going wrong with this script: <script type="text/javascript"> var err = document.getElementById("errmsg"); function checkInput(inPut) { if (inPut.getValue() == "") { err.setStyle('display', 'block'); err.setTextValue("Field cannot be empty!"); inPut.focus(); return false; } else { return true; } } function checkTextBox(textBox) { if (textBox.getValue() == "") { err.setStyle('display', 'block'); err.setTextValue("Field cannot be empty!"); textBox.focus(); return false; } else if (!checkValidity(textBox.getValue())) { err.setStyle('display', 'block'); err.setTextValue("Please enter a valid email address!"); textBox.focus(); return false; } else { return true; } } . . . <div id="errmsg" class="invalid" style="display:none;"></div> <br /> . . . <input type="text" tabindex="1" name="name" id="name" class="input_contact" onblur="checkInput(this);"/> <br /> . . . <input type="text" tabindex="2" name="email" id="email" class="input_contact" onblur="checkTextBox(this);"/> <br /> it's a form in facebook app but while the fbjs works, i assume there's a problem with my basic javascript.

  • Add inner-marging to a 4 columns CSS

    - by Martín Marconcini
    I am not a CSS expert (mainly because I haven’t had the need to use much HTML/CSS stuff lately), so I came up with the following style/divs to create a 4 column layout: <style type="text/css"> <!-- .columns:after { content: "."; display: block; height: 0; clear: both; visibility: hidden; } * html .columns {height: 1%;} .columns{ display:inline-block; } .columns{ display:block; } .columns .column{ float:left; overflow:hidden; display:inline; } .columns .last{ float:right; } .col4 .first{ left: auto;width:25%; } .col4 .second{ left: auto;width:25%; } .col4 .third{ left: auto;width:25%; } .col4 .last{ left: auto;width:25%; } --> </style> note: most of this stuff comes from this google result, I just adapted it to 4 columns. The HTML then looks like this: <div class="columns col4"> <div class="column first”> SOME TEXT </div><!-- /.first -—> <div class="column second”> MORE TEXT</div><!—- /.second -—> <div class="column third”> SOME MORE TEXT </div><!—- /.third --> <div class="column last”> SOME LAST TEXT </div><!-- /.last -—> </div><!-- /.columns --> Ok, I’ve simplified that a bit (there’s a small image and some < h2 text in there too) but the thing is that I’d like to add some space between the columns. Here’s how it looks now: Do you have any idea what CSS property should I touch? note: If I add margin or padding, one column shifts down because (as I understand it) it doesn’t fit. There might be other CSSs as well, since this came in a template (I have been asked for this change, but I didn’t do any of this, as usual). Thanks for any insight.

  • Ruby New dnssd (bonjour zeroconf) service not appearing while browsing

    - by Poul
    Here is my simple zeroconf (aka bonjour dnssd) browser. If I have other services running when I start the browser I can see it (the 'resolved to' line prints to the screen). However, if I start up another service while this browser is running it will not appear. It just waits at the top of the block so I would expect it to enter the block once a new service is registered. Any ideas? require 'rubygems' require 'dnssd' browser = DNSSD::Service.new browser.browse '_http._tcp.' do |reply| #<-- code seems to wait here for more services DNSSD.resolve reply do |r| puts "resolved to: http://#{r.target}:#{r.port}" end end #example service register_service = DNSSD::register( "My Service","_http._tcp", nil, my_port) do puts "* Registering the service *" end
