  • Bug in Safari: options.length = 0; not working as expected in Safari 4

    - by Stefan
    This is not a real question, but rather an answer to save some others the hassle of tracking this nasty bug down. I wasted hours finding this out. When using options.length = 0; to reset all options of a select element in safari, you can get mixed results depending on wether you have the Web Inspector open or not. If the web inspector is open you use myElement.options.length = 0; and after that query the options.length(), you might get back 1 instead of 0 (expected) but only if the Web Inspector is open (which is often the case when debugging problem like this). Workaround: Close the Web Inspector or call myElement.options.length = 0; twice like so: myElement.options.length = 0; myElement.options.length = 0; Testcase: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Testcase</title> <script type="text/javascript" language="javascript" charset="utf-8"> function test(el){ var el = document.getElementById("sel"); alert("Before calling options.length=" + el.options.length); el.options.length = 0; alert("After calling options.length=" + el.options.length); } </script> </head> <body onLoad="test();"> <p> Make note of the numbers displayed in the Alert Dialog, then open Web inspector, reload this page and compare the numbers. </p> <select id="sel" multiple> <option label="a----------" value="a"></option> <option label="b----------" value="b"></option> <option label="c----------" value="c"></option> </select> </body> </html>

  • choosing an image locally from http url and serving that image without a server round trip

    - by serverman
    Hi folks I am a complete novice to Flash (never created anything in flash). I am quite familiar with web applications (J2EE based) and have a reasonable expertise in Javascript. Here is my requirement. I want the user to select (via an html form) an image. Normally in the post, this image would be sent to server and may be stored there to be served later. I do not want that. I want to store this image locally and then serve it via HTTP to the user. So, the flow is: 1. Go to the "select image url":mywebsite.com/selectImage Browse the image and select the image This would transfer control locally to some code running on the client (Javascript or flash), which would then store the image locally at some place on the client machine. Go to the "show image url": mywebsite.com/showImage This would eventually result in some client code running on the browser that retrieves the image and renders it (without any server round trips.) I considered the following options: Use HTML5 local storage. Since I am a complete novice to flash, I looked into this. I found that it is fairly straightforward to store and retrieve images in javascript (only strings are allowed but I am hoping storing base64 encoded strings would work at least for small images). However, how do I serve the image via http url that points to my server without a server round trip? I saw the interesting article at http://hacks.mozilla.org/category/fileapi/ but that would work only in firefox and I need to work on all latest browsers (at least the ones supporting HTML5 local storage) Use flash SharedObjects. OK, this would have been good - the only thing is I am not sure where to start. Snippets of actionscripts to do this are scattered everywhere but I do not know how to use those scripts in an actual html page:) I do not need to create any movies or anything - just need to store an image and serve it locally. If I go this route, I would also use it to store other "strings" locally. If you suggest this, please give me the exact steps (could be pointers to other web sites) on how to do this. I would like to avoid paying for any flash development environment software ideally:) Thank you!

  • remove/ignore float from outer div

    - by acidzombie24
    This may sound weird but i have some css which aligns mys divs. In one place i also use http://www.brunildo.org/test/img_center.html which centers images. Now i want my divs inside a larger div to go to another line if this one gets full. float: left seems to be the answer. The problem is it ruins my formatting. Including solution in the above link. I have this test code. If i remove the width and float it looks fine except it may take up too much space and not go to another line. I was thinking i could use float on an outerdiv and center the image within. However float: left is still breaking it. I am hoping there is a way to remove the float so each div does go left but the div inside centers correctly not breaking my formatting. <style type="text/css"> .wraptocenter { display: table-cell; text-align: center; vertical-align: middle; width: 200px; height: 200px; background: blue; } .wraptocenter * { vertical-align: middle; } /*\*//*/ .wraptocenter { display: block; } .wraptocenter span { display: inline-block; height: 100%; width: 1px; } /**/ div.c { background: red; overflow: hidden; min-width: 400px; max-width: 400px; } div.c div { float: left; } </style> <!--[if lt IE 8]><style> .wraptocenter span { display: inline-block; height: 100%; } </style><![endif]--> <div class="c"> <div> <div> <div class="wraptocenter"><span></span><img src="a.jpg" alt="/a.jpg"></div> <div class="wraptocenter"><span></span><img src="a.jpg" alt="/a.jpg"></div> <div class="wraptocenter"><span></span><img src="a.jpg" alt="/a.jpg"></div> </div></div></div>

  • Preoblem with Precision floating point operation in C

    - by Microkernel
    Hi Guys, For one of my course project I started implementing "Naive Bayesian classifier" in C. My project is to implement a document classifier application (especially Spam) using huge training data. Now I have problem implementing the algorithm because of the limitations in the C's datatype. ( Algorithm I am using is given here, http://en.wikipedia.org/wiki/Bayesian_spam_filtering ) PROBLEM STATEMENT: The algorithm involves taking each word in a document and calculating probability of it being spam word. If p1, p2 p3 .... pn are probabilities of word-1, 2, 3 ... n. The probability of doc being spam or not is calculated using Here, probability value can be very easily around 0.01. So even if I use datatype "double" my calculation will go for a toss. To confirm this I wrote a sample code given below. #define PROBABILITY_OF_UNLIKELY_SPAM_WORD (0.01) #define PROBABILITY_OF_MOSTLY_SPAM_WORD (0.99) int main() { int index; long double numerator = 1.0; long double denom1 = 1.0, denom2 = 1.0; long double doc_spam_prob; /* Simulating FEW unlikely spam words */ for(index = 0; index < 162; index++) { numerator = numerator*(long double)PROBABILITY_OF_UNLIKELY_SPAM_WORD; denom2 = denom2*(long double)PROBABILITY_OF_UNLIKELY_SPAM_WORD; denom1 = denom1*(long double)(1 - PROBABILITY_OF_UNLIKELY_SPAM_WORD); } /* Simulating lot of mostly definite spam words */ for (index = 0; index < 1000; index++) { numerator = numerator*(long double)PROBABILITY_OF_MOSTLY_SPAM_WORD; denom2 = denom2*(long double)PROBABILITY_OF_MOSTLY_SPAM_WORD; denom1 = denom1*(long double)(1- PROBABILITY_OF_MOSTLY_SPAM_WORD); } doc_spam_prob= (numerator/(denom1+denom2)); return 0; } I tried Float, double and even long double datatypes but still same problem. Hence, say in a 100K words document I am analyzing, if just 162 words are having 1% spam probability and remaining 99838 are conspicuously spam words, then still my app will say it as Not Spam doc because of Precision error (as numerator easily goes to ZERO)!!!. This is the first time I am hitting such issue. So how exactly should this problem be tackled?

  • build-helper-maven-plugin add-source does not working when trying to add linked resources

    - by Julian
    I am new to maven and hit a problem that looks easy in the first place but I already kept me busy for a whole day about and no way to get it working. First as part of running eclipse:eclipse plugin I create a linked folder like below: <linkedResources> <linkedResource> <name>properties</name> <type>2</type> <location>${PARENT-2-PROJECT_LOC}/some_other_project/properties</location> </linkedResource> <linkedResource> <name>properties/messages.properties</name> <type>1</type> <location>${PARENT-2-PROJECT_LOC}/some_other_project/properties/messages.properties</location> </linkedResource> And then I am adding that folder as a source folder like below: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <version>1.7</version> <executions> <execution> <id>add-source</id> <phase>generate-sources</phase> <goals> <goal>add-source</goal> </goals> <configuration> <sources> <source>properties</source> <source>some_real_folder</source> </sources> </configuration> </execution> </executions> </plugin> However when I am looking at the generated .classpath in eclipse the “some_real_folder” is there but the “properties” is not. It looks like by default the build-helper-maven-plugin will check if the folder is there and if it is not it won’t add it. I am using maven 3.0.4 outside eclipse to run the build and I can see in the maven logs something like this: [INFO] Source directory: <some path>\properties added. This is my project structure: project1 \-- properties (this is the real folder) project2 \-- some_real_folder \-- properties (this is the link resource pointing to the project1/properties folder) All I need is to have both "some_real_folder" and the linked resource "properties" added to the .classpath of the project2

  • Linux termios VTIME not working?

    - by San Jacinto
    We've been bashing our heads off of this one all morning. We've got some serial lines setup between an embedded linux device and an Ubuntu box. Our reads are getting screwed up because our code usually returns two (sometimes more, sometimes exactly one) message reads instead of one message read per actual message sent. Here is the code that opens the serial port. InterCharTime is set to 4. void COMBaseClass::OpenPort() { cerr<< "openning port"<< port <<"\n"; struct termios newtio; this->fd = -1; int fdTemp; fdTemp = open( port, O_RDWR | O_NOCTTY); if (fdTemp < 0) { portOpen = 0; cerr<<"problem openning "<< port <<". Retrying"<<endl; usleep(1000000); return; } newtio.c_cflag = BaudRate | CS8 | CLOCAL | CREAD ;//| StopBits; newtio.c_iflag = IGNPAR; newtio.c_oflag = 0; /* set input mode (non-canonical, no echo,...) */ newtio.c_lflag = 0; newtio.c_cc[VTIME] = InterCharTime; /* inter-character timer in .1 secs */ newtio.c_cc[VMIN] = readBufferSize; /* blocking read until 1 char received */ tcflush(fdTemp, TCIFLUSH); tcsetattr(fdTemp,TCSANOW,&newtio); this->fd = fdTemp; portOpen = 1; } The other end is configured similarly for communication, and has one small section of particular iterest: while (1) { sprintf(out, "\r\nHello world %lu", ++ulCount); puts(out); WritePort((BYTE *)out, strlen(out)+1); sleep(2); } //while Now, when I run a read thread on the receiving machine, "hello world" is usually broken up over a couple messages. Here is some sample output: 1: Hello 2: world 1 3: Hello 4: world 2 5: Hello 6: world 3 where number followed by a colon is one message recieved. Can you see any error we are making? Thank you. Edit: For clarity, please view section 3.2 of this resource href="http://www.faqs.org/docs/Linux-HOWTO/Serial-Programming-HOWTO.html. To my understanding, with a VTIME of a couple seconds (meaning vtime is set anywhere between 10 and 50, trial-and-error), and a VMIN of 1, there should be no reason that the message is broken up over two separate messages.

  • Hibernate Persistence problems with Bean Mapping (Dozer)

    - by BuffaloBuffalo
    I am using Hibernate 3, and having a particular issue when persisting a new Entity which has an association with an existing detached entity. Easiest way to explain this is via code samples. I have two entities, FooEntity and BarEntity, of which a BarEntity can be associated with many FooEntity: @Entity public class FooEntity implements Foo{ @Id private Long id; @ManyToOne(targetEntity = BarEntity.class) @JoinColumn(name = "bar_id", referencedColumnName = "id") @Cascade(value={CascadeType.ALL}) private Bar bar; } @Entity public class BarEntity implements Bar{ @Id private Long id; @OneToMany(mappedBy = "bar", targetEntity = FooEntity.class) private Set<Foo> foos; } Foo and Bar are interfaces that loosely define getters for the various fields. There are corresponding FooImpl and BarImpl classes that are essentially just the entity objects without the annotations. What I am trying to do is construct a new instance of FooImpl, and persist it after setting a number of fields. The new Foo instance will have its 'bar' member set to an existing Bar (runtime being a BarEntity) from the database (retrieved via session.get(..)). After the FooImpl has all of its properties set, Apache Dozer is used to map between the 'domain' object FooImpl and the Entity FooEntity. What Dozer is doing in the background is instantiating a new FooEntity and setting all of the matching fields. BarEntity is cloned as well via instantiation and set the FooEntity's 'bar' member. After this occurs, passing the new FooEntity object to persist. This throws the exception: org.hibernate.PersistentObjectException: detached entity passed to persist: com.company.entity.BarEntity Below is in code the steps that are occurring FooImpl foo = new FooImpl(); //returns at runtime a persistent BarEntity through session.get() Bar bar = BarService.getBar(1L); foo.setBar(bar); ... //This constructs a new instance of FooEntity, with a member 'bar' which itself is a new instance that is detached) FooEntity entityToPersist = dozerMapper.map(foo, FooEntity.class); ... session.persist(entityToPersist); I have been able to resolve this issue by either removing or changing the @Cascade annotation, but that limits future use for say adding a new Foo with a new Bar attached to it already. Is there some solution here I am missing? I would be surprised if this issue hasn't been solved somewhere before, either by altering how Dozer Maps the children of Foo or how Hibernate reacts to a detached Child Entity.

  • Why is this line breaking Rails with Passenger on DreamHost?

    - by Frew
    Ok, so I have a Rails app set up on DreamHost and I had it working a while ago and now it's broken.

  • Drupal incorrectly espaces tags in javascript

    - by sergdev
    I installed drupal-6.16. I applied the patch from the post http://drupal.org/node/222926#comment-930745. It works correctly in simple cases. But for following code for counter is handled incorrectly: <br><br> Text <br><br> <!-- counter.1Gb.ua --> <script language="javascript" type="text/javascript"> cgb_js="1.0"; cgb_r=""+Math.random()+"&r="+ escape(document.referrer)+"&pg="+ escape(window.location.href); document.cookie="rqbct=1; path=/"; cgb_r+="&c="+ (document.cookie?"Y":"N"); </script><script language="javascript1.1" type="text/javascript"> cgb_js="1.1";cgb_r+="&j="+ (navigator.javaEnabled()?"Y":"N")</script> <script language="javascript1.2" type="text/javascript"> cgb_js="1.2"; cgb_r+="&wh="+screen.width+ 'x'+screen.height+"&px="+ (((navigator.appName.substring(0,3)=="Mic"))? screen.colorDepth:screen.pixelDepth)</script> <script language="javascript1.3" type="text/javascript"> cgb_js="1.3"</script> <script language="javascript" type="text/javascript">cgb_r+="&js="+cgb_js; document.write("<a href='http://www.1Gb.ua?cnt=1416'>"+ "<img src='http://counter.1Gb.ua/cnt.aspx?"+ "u=1416&"+cgb_r+ "&' border=0 width=88 height=31 "+ "alt='1Gb.ua counter'><\/a>")</script> <noscript><a href='http://www.1Gb.ua?cnt=1416'> <img src="http://counter.1Gb.ua/cnt.aspx?u=1416" border=0 width="88" height="31" alt="1Gb.ua counter"></a> </noscript> <!-- /counter.1Gb.ua --> It modifies the string "alt='1Gb.ua counter' /><\/a>")</a></script> to "alt='1Gb.ua counter' />&lt;\/a>")</a></script> Does anybody have this code working? If so how this can be fixed? Thanks a lot in advance!

  • PHP resized image functions and S3 upload functions - but how to merge the two?

    - by chocolatecoco
    I am using S3 to store images and I am resizing and compressing images before it gets uploaded using PHP. I'm using this class for storing the images to an S3 bucket - http://undesigned.org.za/2007/10/22/amazon-s3-php-class This all works fine if I'm not doing any file processing before the file is uploaded because it reads the file upload from the $_FILES array. The problem is I am resizing and compressing the image before storing to the S3 bucket. So I'm no longer able to read from the $_FILES array. The functions for resizing: public function resizeImage($newWidth, $newHeight, $option="auto") { // *** Get optimal width and height - based on $option $optionArray = $this->getDimensions($newWidth, $newHeight, $option); $optimalWidth = $optionArray['optimalWidth']; $optimalHeight = $optionArray['optimalHeight']; // *** Resample - create image canvas of x, y size $this->imageResized = imagecreatetruecolor($optimalWidth, $optimalHeight); imagecopyresampled($this->imageResized, $this->image, 0, 0, 0, 0, $optimalWidth, $optimalHeight, $this->width, $this->height); // *** if option is 'crop', then crop too if ($option == 'crop') { $this->crop($optimalWidth, $optimalHeight, $newWidth, $newHeight); } } The script I am using to store the file after resizing and compressing to a local directory: public function saveImage($savePath, $imageQuality="100") { // *** Get extension $extension = strrchr($savePath, '.'); $extension = strtolower($extension); switch($extension) { case '.jpg': case '.jpeg': if (imagetypes() & IMG_JPG) { imagejpeg($this->imageResized, $savePath, $imageQuality); } break; case '.gif': if (imagetypes() & IMG_GIF) { imagegif($this->imageResized, $savePath); } break; case '.png': // *** Scale quality from 0-100 to 0-9 $scaleQuality = round(($imageQuality/100) * 9); // *** Invert quality setting as 0 is best, not 9 $invertScaleQuality = 9 - $scaleQuality; if (imagetypes() & IMG_PNG) { imagepng($this->imageResized, $savePath, $invertScaleQuality); } break; // ... etc default: // *** No extension - No save. break; } imagedestroy($this->imageResized); } with this PHP code to invoke it: $resizeObj = new resize("$images_dir/$filename"); $resizeObj -> resizeImage($thumbnail_width, $thumbnail_height, 'crop'); $resizeObj -> saveImage($images_dir."/tb_".$filename, 90); How do I modify the code above so I can pass it through this function: $s3->putObjectFile($thefile, "s3bucket", $s3directory, S3::ACL_PUBLIC_READ)

  • Eclipse javascript character encoding

    - by Bardock
    Hi, I'd like to display some language specific characters from javascript but I can't. My app is a Java webapp and the front end is jQuery. All the characters that are sended from the server - in a JSP or with AJAX - are displayed properly. When I want to display some text hardcoded in to the javascript file it's broken. I'm using Eclipse. In the JSP's header I use: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> I've tried this (charset in the script element) too: <script type="text/javascript" charset="utf-8"><c:import url="/JS/mainJS.js" /></script> In my Eclipse I've set the project properties / text file encoding to UTF-8 AND I've checked the JS files' resource properties / text file encoding that is UTF-8 too. But when I try this: $.test = function(){ var s = "éééáááuuuu"; alert(s); } I get: éééáááűűűű The strange thing is that: When I try in a separate html file (in the same project), It's working: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <style type="text/css"> body {background: #c0c0c0;} </style> <script type="text/javascript"> $(document).ready(function(){ var s = "éááuuúúú"; $("#console").text(s); alert(s); }) </script> </head> <body> <div id="console"></div> </body> </html> Even if I DO NOT use any content type and page encoding settings. What is the problem? What shall I do? (I'm using Apache Tomcat integrated in Eclipse) Thanks in advance!

  • Hibernate/Spring: getHibernateTemplate().save(...) Freezes/Hangs

    - by ashes999
    I'm using Hibernate and Spring with the DAO pattern (all Hibernate dependencies in a *DAO.java class). I have nine unit tests (JUnit) which create some business objects, save them, and perform operations on them; the objects are in a hash (so I'm reusing the same objects all the time). My JUnit setup method calls my DAO.deleteAllObjects() method which calls getSession().createSQLQuery("DELETE FROM <tablename>").executeUpdate() for my business object table (just one). One of my unit tests (#8/9) freezes. I presumed it was a database deadlock, because the Hibernate log file shows my delete statement last. However, debugging showed that it's simply HibernateTemplate.save(someObject) that's freezing. (Eclipse shows that it's freezing on HibernateTemplate.save(Object), line 694.) Also interesting to note is that running this test by itself (not in the suite of 9 tests) doesn't cause any problems. How on earth do I troubleshoot and fix this? Also, I'm using @Entity annotations, if that matters. Edit: I removed reuse of my business objects (use unique objects in every method) -- didn't make a difference (still freezes). Edit: This started trickling into other tests, too (can't run more than one test class without getting something freezing) Transaction configuration: <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <tx:advice id="txAdvice" transaction-manager="txManager"> <!-- the transactional semantics... --> <tx:attributes> <!-- all methods starting with 'get' are read-only --> <tx:method name="get*" read-only="true" /> <tx:method name="find*" read-only="true" /> <!-- other methods use the default transaction settings (see below) --> <tx:method name="*" /> </tx:attributes> </tx:advice> <!-- my bean which is exhibiting the hanging behavior --> <aop:config> <aop:pointcut id="beanNameHere" expression="execution(* com.blah.blah.IMyDAO.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="beanNameHere" /> </aop:config>

  • Table row height in Internet Explorer

    - by Fritz H
    I have the following table: <table> <tr> <td style="height: 7px; width: 7px"> A1 </td> <td style="height: 7px"> B1 </td> <td style="height: 7px; width: 7px"> C1 </td> </tr> <tr> <td style="width: 7px"> A2 </td> <td> B2 </td> <td style="width: 7px"> C2 </td> </tr> <tr> <td style="height: 7px; width: 7px"> A3 </td> <td style="height: 7px"> B3 </td> <td style="height: 7px; width: 7px"> C3 </td> </tr> </table> The basic idea is that the first row must be 7 pixels high. The left- and rightmost cells (A1 and C1) must be 7px wide, and the middle cell (B1) must scale according to the width of the table. The same goes for the bottom row (A3, B3, C3). The middle row, however, needs to scale in height - in other words, it needs to be (tableheight - 14px). The left- and rightmost cells (A2, C2) need to be 7 pixels wide. An example: 7px x 7px |------|-------------------------|------| --- +------+-------------------------+------+ | | | | | | 7px | | | | | | | | | --- +------+-------------------------+------+ | | | | | | | | | | | | | | | | | | | | | y | | | | | | | | | | | | | | | | | | | | | | | | --- +------+-------------------------+------+ | | | | | | 7px | | | | | | | | | --- +------+-------------------------+------+ HOWEVER: In Internet Explorer, the widths work fine (columns A and C are 7px, column B scales dynamically) - but the heights don't. Rows 1, 2 and 3 turn out to be exactly 33% of the height of the table, no matter what I do. Unfortunately I have to use this table, so replacing it with a set of DIVs is not an option. I have the following DOCTYPE: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> I need to keep this, as some other elements on the page rely on some complex CSS-based layouts. Can anyone point me in the right direction to whip this into shape for IE? EDIT: Should have mentioned earlier - this table is resized on the fly using javascript.

  • How does Page.IsValid work?

    - by Lijo
    I have following code with a RequiredFieldValidator. The EnableClientScript property is set as "false" in the validation control. Also I have disabled script in browser. I am NOT using Page.IsValid in code behind. Still, when I submit without any value in textbox I will get error message. From comments of @Dai, I came to know that this can be an issue, if there is any code in Page_Load that is executed in a postback. There will be no validation errors thrown. (However, for button click handler, there is no need to check Page.IsValid) if (Page.IsPostBack) { string value = txtEmpName.Text; txtEmpName.Text = value + "Appended"; } QUESTION Why the server side validation does not happen before Page_Load? Why it works fine when I use Page.IsValid? UPDATE It seems like, we need to add If(Page.IsValid) in button click also if we are using a Custom Validator with server side validation. Refer CustomValidator not working well. Note: Client side validation question is present here: Whether to use Page_IsValid or Page_ClientValidate() (for Client Side Events) MARKUP <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script type="text/javascript"> alert('haiii'); </script> </head> <body> <form id="form1" runat="server"> <div> <asp:ValidationSummary runat="server" ID="vsumAll" DisplayMode="BulletList" CssClass="validationsummary" ValidationGroup="ButtonClick" /> <asp:TextBox ID="txtEmpName" runat="server"></asp:TextBox> <asp:RequiredFieldValidator ID="valEmpName" runat="server" ControlToValidate="txtEmpName" EnableClientScript="false" ErrorMessage="RequiredFieldValidator" Text="*" Display="Dynamic" ValidationGroup="ButtonClick"></asp:RequiredFieldValidator> <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" ValidationGroup="ButtonClick" /> </div> </form> </body> </html> CODE BEHIND protected void Button1_Click(object sender, EventArgs e) { string value = txtEmpName.Text; SubmitEmployee(value); } References: Should I always call Page.IsValid?

In IE8, however, the list item tabs are on separate lines When I add an XHTML doctype, the page renders correctly in IE8 except the footer is not drawn at the bottom of the page in IE8, Chrome or Firefox, i.e. the footer sits directly below the menu bar. Example doctype: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> What am I doing wrong?

  • h:selectOneMenu not populating a 'selected' item

    - by dann.dev
    I'm having trouble with an h:selectOneMenu not having a selected item when there is already something set on the backing bean. I am using seam and have specified a customer converter. When working on my 'creation' page, everything works fine, something from the menu can be selected, and when the page is submitted, the correct value is assigned and persisted to the database as well. However when I work on my 'edit' page the menu's default selection is not the current selection. i have gone through and confirmed that something is definitely set etc. My selectOneMenu looks like this: <h:selectOneMenu id="selVariable" value="#{customer.variableLookup}" converter="#{variableLookupConverter}"> <s:selectItems var="source" value="#{customerReferenceHelper.variableLookups()}" label="#{source.name}" /> </h:selectOneMenu> And the converter is below. It very simple and just turns the id from string to int and back etc: @Name( "sourceOfWealthLookupConverter" ) public class SourceOfWealthLookupConverter implements Serializable, Converter { @In private CustomerReferenceHelper customerReferenceHelper; @Override public Object getAsObject( FacesContext arg0, UIComponent arg1, String arg2 ) { VariableLookup variable= null; try { if ( "org.jboss.seam.ui.NoSelectionConverter.noSelectionValue".equals( arg2 ) ) { return null; } CustomerReferenceHelper customerReferenceHelper = ( CustomerReferenceHelper ) Contexts.getApplicationContext().get( "customerReferenceHelper" ); Integer id = Integer.parseInt( arg2 ); source = customerReferenceHelper.getVariable( id ); } catch ( NumberFormatException e ) { log.error( e, e ); } return variable; } @Override public String getAsString( FacesContext arg0, UIComponent arg1, Object arg2 ) { String result = null; VariableLookup variable= ( VariableLookup ) arg2; Integer id = variable.getId(); result = String.valueOf( id ); return result; } } I've seen a few things about it possibly being the equals() method on the class, (that doesn't add up with everything else working, but I overrode it anyway as below, where the hashcode is just the id (id is a unique identifier for each item). Equals method: @Override public boolean equals( Object other ) { if ( other == null ) { return false; } if ( this == other ) { return true; } if ( !( other instanceof VariableLookup ) ) { return false; } VariableLookup otherVariable = ( VariableLookup ) other; if ( this.hashCode() == otherVariable.hashCode() ) { return true; } return false; } I'm at my wits end with this, I can't find what I could have missed?! Any help would be much appreciated

  • Drupal's profile_save_profile Doesn't Work in hook_cron, When Run by the Server's cron

    - by anschauung
    I have a problem with the following implementation of hook_cron in Drupal 6.1.3. The script below runs exactly as expected: it sends a welcome letter to new members, and updates a hidden field in their profile to designate that the letter has been sent. There are no errors in the letter, all new members are accounted for, etc. The problem is that the last line -- updating the profile -- doesn't seem to work when Drupal cron is invoked by the 'real' cron on the server. When I run cron manually (such as via /admin/reports/status/run-cron) the profile fields get updated as expected. Any suggestions as to what might be causing this? (Note, since someone will suggest it: members join by means outside of Drupal, and are uploaded to Drupal nightly, so Drupal's built-in welcome letters won't work (I think).) <?php function foo_cron() { // Find users who have not received the new member letter, // and send them a welcome email // Get users who have not recd a message, as per the profile value setting $pending_count_sql = "SELECT COUNT(*) FROM {profile_values} v WHERE (v.value = 0) AND (v.fid = 7)"; //fid 7 is the profile field for profile_intro_email_sent if (db_result(db_query($pending_count_sql))) { // Load the message template, since we // know we have users to feed into it. $email_template_file = "/home/foo/public_html/drupal/" . drupal_get_path('module', 'foo') . "/emails/foo-new-member-email-template.txt"; $email_template_data = file_get_contents($email_template_file); fclose($email_template_fh); //We'll just pull the uid, since we have to run user_load anyway $query = "SELECT v.uid FROM {profile_values} v WHERE (v.value = 0) AND (v.fid = 7)"; $result = db_query(($query)); // Loop through the uids, loading profiles so as to access string replacement variables while ($item = db_fetch_object($result)) { $new_member = user_load($item->uid); $translation_key = array( // ... code that generates the string replacement array ... ); // Compose the email component of the message, and send to user $email_text = t($email_template_data, $translation_key); $language = user_preferred_language($new_member); // use member's language preference $params['subject'] = 'New Member Benefits - Welcome to FOO!'; $params['content-type'] = 'text/plain; charset=UTF-8; format=flowed;'; $params['content'] = $email_text; drupal_mail('foo', 'welcome_letter', $new_member->mail, $language, $params, 'webmaster@foo.org'); // Mark the user's profile to indicate that the message was sent $change = array( // Rebuild all of the profile fields in this category, // since they'll be deleted otherwise 'profile_first_name' => $new_member->profile_first_name, 'profile_last_name' => $new_member->profile_last_name, 'profile_intro_email_sent' => 1); profile_save_profile($change, $new_member, "Membership Data"); } } }

  • jQuery animate slidding background image using mouse position wont stop... just keeps going

    - by simian
    I have a neat little jQuery script I am working on. Goal: parent div with overflow hidden holds a larger div with image. When I move the mouse to the left or right of the parent div, the div with image changes margin-left to move left or right. Problem is... if I move the mouse out of the parent div (left or right), the image keeps going. I need the image to stop when the mouse is not on the inside left or right edge of the parent div. Any ideas? <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> //<![CDATA[ jQuery.noConflict (); jQuery(document).ready(function(){ jQuery('#container').mousemove(function(e){ var parentWidth = jQuery('#container').width(); var parentWidthLeft = Math.round(.1 * jQuery('#container').width()); var parentWidthRight = Math.round(jQuery('#container').width() - parentWidthLeft); var parentHeight = jQuery('#container').height(); var parentOffset = jQuery('#container').offset(); var X = Math.round(e.pageX - parentOffset.left); var Y = Math.round(e.pageY - parentOffset.top); if (X<parentWidthLeft) { jQuery('#image').animate({'left': '-' + parentWidth }, 5000); } if (X>parentWidthRight) { jQuery('#image').animate({'left': parentWidth }, 5000); } if (X<=parentWidthRight && X>=parentWidthLeft) { jQuery('#image').stop(); } if (X<1) { jQuery('#image').stop(); } }); jQuery('#container').mouseleave(function(){ jQuery('#image').stop(); }); }); // ]]> </script> </head> <body> <div id="container" style="width: 500px; height: 500px; overflow: hidden; border: 10px solid #000; position: relative; margin: auto auto;"> <div id="image" style="position: absolute; left: 0; top: 0;"><img src="http://dump4free.com/imgdump/1/Carmen-Electra_1wallpaper1024x768.jpg" alt="" /></div> </div> </body> </html>

  • session fixation

    - by markiv
    Hi All, I am new to web development, and trying to get a hold on security issues. I went through this article on http://guides.rubyonrails.org/security.html these are some of the steps the author has mentioned how an attacker fixes session. 1. The attacker creates a valid session id: He loads the login page of the web application where he wants to fix the session, and takes the session id in the cookie from the response (see number 1 and 2 in the image). 2. He possibly maintains the session. Expiring sessions, for example every 20 minutes, greatly reduces the time-frame for attack. Therefore he accesses the web application from time to time in order to keep the session alive. 3. Now the attacker will force the user’s browser into using this session id (see number 3 in the image). As you may not change a cookie of another domain (because of the same origin policy), the attacker has to run a JavaScript from the domain of the target web application. Injecting the JavaScript code into the application by XSS accomplishes this attack. Here is an example: <script>?document.cookie="_session_id=16d5b78abb28e3d6206b60f22a03c8d9";?</script>. Read more about XSS and injection later on. 4. The attacker lures the victim to the infected page with the JavaScript code. By viewing the page, the victim’s browser will change the session id to the trap session id. 5. As the new trap session is unused, the web application will require the user to authenticate. 6. From now on, the victim and the attacker will co-use the web application with the same session: The session became valid and the victim didn’t notice the attack. I dont understand couple of points. i) why is user made to login in step5, since session is sent through. ii) I saw possible solutions on wiki, like user properties check and others why cant we just reset the session for the user whoever is login in when they enter username and password in step5? Thanks in advance Markiv

  • Is there a way to have element behind a div (links) clickable in areas where the div is "transparent

    - by Adam
    I have a block element that is positioned absolutely and some other elements on page that are positioned fixed. The effect is the block on top floats over the page which works well. The links in the elements at the bottom underneath are not clickable. They shouldn't be when the content of the div is over them, but when the "marginal" areas which are transparent are over the links they are visible, but clicks only register to the covering div. The problem only happens when the padding covers the div. But if I just rely on the margin the bottom margin is ignored by browser so the scroll doesn't go high enough up. To solve this I resort to padding at the bottom. This is the problem. Is there a clean way around this? I realize I could have the underneath elements doubled and place on top, but opacity set to 0. That is an undesirable solution however. Sample of the problem: <!DOCTYPE html> <html lang='en' xml:lang='en' xmlns='http://www.w3.org/1999/xhtml'> <head> <style> #top, #bottom { position: fixed; border: 1 px solid #333; background-color: #eee; left: 100px; padding: 8px; } #top { top: 0; z-index: 1; } #bottom { bottom: 0; z-index: 2; } #contentWrapper { position: absolute; margin: 100px 0 0 0; /* Padding is used to make sure the scroll goes up further on the page */ padding: 0 0 100px 0; width: 600px; z-index: 3; } #content { border: 1 px solid #333; background-color: #eee; height: 1000px; } </style> </head> <body> <div id='top'><a href="#">Top link</a></div> <div id='bottom'><a href="#">Bottom link</a></div> <div id='contentWrapper'> <div id='content'>Some content</div> </div> </body> </html>

  • Custom InputIterator for Boost graph (BGL)

    - by Shadow
    Hi, I have a graph with custom properties to the vertices and edges. I now want to create a copy of this graph, but I don't want the vertices to be as complex as in the original. By this I mean that it would suffice that the vertices have the same indices (vertex_index_t) as they do in the original graph. Instead of doing the copying by hand I wanted to use the copy-functionality of boost::adjacency_list (s. http://www.boost.org/doc/libs/1_37_0/libs/graph/doc/adjacency_list.html): template <class EdgeIterator> adjacency_list(EdgeIterator first, EdgeIterator last, vertices_size_type n, edges_size_type m = 0, const GraphProperty& p = GraphProperty()) The description there says: The EdgeIterator must be a model of InputIterator. The value type of the EdgeIterator must be a std::pair, where the type in the pair is an integer type. The integers will correspond to vertices, and they must all fall in the range of [0, n). Unfortunately I have to admit that I don't quite get it how to define an EdgeIterator that is a model of InputIterator. Here's what I've succeded so far: template< class EdgeIterator, class Edge > class MyEdgeIterator// : public input_iterator< std::pair<int, int> > { public: MyEdgeIterator() {}; MyEdgeIterator(EdgeIterator& rhs) : actual_edge_it_(rhs) {}; MyEdgeIterator(const MyEdgeIterator& to_copy) {}; bool operator==(const MyEdgeIterator& to_compare) { return actual_edge_it_ == to_compare.actual_edge_it_; } bool operator!=(const MyEdgeIterator& to_compare) { return !(*this == to_compare); } Edge operator*() const { return *actual_edge_it_; } const MyEdgeIterator* operator->() const; MyEdgeIterator& operator ++() { ++actual_edge_it_; return *this; } MyEdgeIterator operator ++(int) { MyEdgeIterator<EdgeIterator, Edge> tmp = *this; ++*this; return tmp; } private: EdgeIterator& actual_edge_it_; } However, this doesn't work as it is supposed to and I ran out of clues. So, how do I define the appropriate InputIterator?

  • Announcing the Release of Visual Studio 2013 and Great Improvements to ASP.NET and Entity Framework

    - by ScottGu
    Today we released VS 2013 and .NET 4.5.1. These releases include a ton of great improvements, and include some fantastic enhancements to ASP.NET and the Entity Framework.  You can download and start using them now. Below are details on a few of the great ASP.NET, Web Development, and Entity Framework improvements you can take advantage of with this release.  Please visit http://www.asp.net/vnext for additional release notes, documentation, and tutorials. One ASP.NET With the release of Visual Studio 2013, we have taken a step towards unifying the experience of using the different ASP.NET sub-frameworks (Web Forms, MVC, Web API, SignalR, etc), and you can now easily mix and match the different ASP.NET technologies you want to use within a single application. When you do a File-New Project with VS 2013 you’ll now see a single ASP.NET Project option: Selecting this project will bring up an additional dialog that allows you to start with a base project template, and then optionally add/remove the technologies you want to use in it.  For example, you could start with a Web Forms template and add Web API or Web Forms support for it, or create a MVC project and also enable Web Forms pages within it: This makes it easy for you to use any ASP.NET technology you want within your apps, and take advantage of any feature across the entire ASP.NET technology span. Richer Authentication Support The new “One ASP.NET” project dialog also includes a new Change Authentication button that, when pushed, enables you to easily change the authentication approach used by your applications – and makes it much easier to build secure applications that enable SSO from a variety of identity providers.  For example, when you start with the ASP.NET Web Forms or MVC templates you can easily add any of the following authentication options to the application: No Authentication Individual User Accounts (Single Sign-On support with FaceBook, Twitter, Google, and Microsoft ID – or Forms Auth with ASP.NET Membership) Organizational Accounts (Single Sign-On support with Windows Azure Active Directory ) Windows Authentication (Active Directory in an intranet application) The Windows Azure Active Directory support is particularly cool.  Last month we updated Windows Azure Active Directory so that developers can now easily create any number of Directories using it (for free and deployed within seconds).  It now takes only a few moments to enable single-sign-on support within your ASP.NET applications against these Windows Azure Active Directories.  Simply choose the “Organizational Accounts” radio button within the Change Authentication dialog and enter the name of your Windows Azure Active Directory to do this: This will automatically configure your ASP.NET application to use Windows Azure Active Directory and register the application with it.  Now when you run the app your users can easily and securely sign-in using their Active Directory credentials within it – regardless of where the application is hosted on the Internet. For more information about the new process for creating web projects, see Creating ASP.NET Web Projects in Visual Studio 2013. Responsive Project Templates with Bootstrap The new default project templates for ASP.NET Web Forms, MVC, Web API and SPA are built using Bootstrap. Bootstrap is an open source CSS framework that helps you build responsive websites which look great on different form factors such as mobile phones, tables and desktops. For example in a browser window the home page created by the MVC template looks like the following: When you resize the browser to a narrow window to see how it would like on a phone, you can notice how the contents gracefully wrap around and the horizontal top menu turns into an icon: When you click the menu-icon above it expands into a vertical menu – which enables a good navigation experience for small screen real-estate devices: We think Bootstrap will enable developers to build web applications that work even better on phones, tablets and other mobile devices – and enable you to easily build applications that can leverage the rich ecosystem of Bootstrap CSS templates already out there.  You can learn more about Bootstrap here. Visual Studio Web Tooling Improvements Visual Studio 2013 includes a new, much richer, HTML editor for Razor files and HTML files in web applications. The new HTML editor provides a single unified schema based on HTML5. It has automatic brace completion, jQuery UI and AngularJS attribute IntelliSense, attribute IntelliSense Grouping, and other great improvements. For example, typing “ng-“ on an HTML element will show the intellisense for AngularJS: This support for AngularJS, Knockout.js, Handlebars and other SPA technologies in this release of ASP.NET and VS 2013 makes it even easier to build rich client web applications: The screen shot below demonstrates how the HTML editor can also now inspect your page at design-time to determine all of the CSS classes that are available. In this case, the auto-completion list contains classes from Bootstrap’s CSS file. No more guessing at which Bootstrap element names you need to use: Visual Studio 2013 also comes with built-in support for both CoffeeScript and LESS editing support. The LESS editor comes with all the cool features from the CSS editor and has specific Intellisense for variables and mixins across all the LESS documents in the @import chain. Browser Link – SignalR channel between browser and Visual Studio The new Browser Link feature in VS 2013 lets you run your app within multiple browsers on your dev machine, connect them to Visual Studio, and simultaneously refresh all of them just by clicking a button in the toolbar. You can connect multiple browsers (including IE, FireFox, Chrome) to your development site, including mobile emulators, and click refresh to refresh all the browsers all at the same time.  This makes it much easier to easily develop/test against multiple browsers in parallel. Browser Link also exposes an API to enable developers to write Browser Link extensions.  By enabling developers to take advantage of the Browser Link API, it becomes possible to create very advanced scenarios that crosses boundaries between Visual Studio and any browser that’s connected to it. Web Essentials takes advantage of the API to create an integrated experience between Visual Studio and the browser’s developer tools, remote controlling mobile emulators and a lot more. You will see us take advantage of this support even more to enable really cool scenarios going forward. ASP.NET Scaffolding ASP.NET Scaffolding is a new code generation framework for ASP.NET Web applications. It makes it easy to add boilerplate code to your project that interacts with a data model. In previous versions of Visual Studio, scaffolding was limited to ASP.NET MVC projects. With Visual Studio 2013, you can now use scaffolding for any ASP.NET project, including Web Forms. When using scaffolding, we ensure that all required dependencies are automatically installed for you in the project. For example, if you start with an ASP.NET Web Forms project and then use scaffolding to add a Web API Controller, the required NuGet packages and references to enable Web API are added to your project automatically.  To do this, just choose the Add->New Scaffold Item context menu: Support for scaffolding async controllers uses the new async features from Entity Framework 6. ASP.NET Identity ASP.NET Identity is a new membership system for ASP.NET applications that we are introducing with this release. ASP.NET Identity makes it easy to integrate user-specific profile data with application data. ASP.NET Identity also allows you to choose the persistence model for user profiles in your application. You can store the data in a SQL Server database or another data store, including NoSQL data stores such as Windows Azure Storage Tables. ASP.NET Identity also supports Claims-based authentication, where the user’s identity is represented as a set of claims from a trusted issuer. Users can login by creating an account on the website using username and password, or they can login using social identity providers (such as Microsoft Account, Twitter, Facebook, Google) or using organizational accounts through Windows Azure Active Directory or Active Directory Federation Services (ADFS). To learn more about how to use ASP.NET Identity visit http://www.asp.net/identity.  ASP.NET Web API 2 ASP.NET Web API 2 has a bunch of great improvements including: Attribute routing ASP.NET Web API now supports attribute routing, thanks to a contribution by Tim McCall, the author of http://attributerouting.net. With attribute routing you can specify your Web API routes by annotating your actions and controllers like this: OAuth 2.0 support The Web API and Single Page Application project templates now support authorization using OAuth 2.0. OAuth 2.0 is a framework for authorizing client access to protected resources. It works for a variety of clients including browsers and mobile devices. OData Improvements ASP.NET Web API also now provides support for OData endpoints and enables support for both ATOM and JSON-light formats. With OData you get support for rich query semantics, paging, $metadata, CRUD operations, and custom actions over any data source. Below are some of the specific enhancements in ASP.NET Web API 2 OData. Support for $select, $expand, $batch, and $value Improved extensibility Type-less support Reuse an existing model OWIN Integration ASP.NET Web API now fully supports OWIN and can be run on any OWIN capable host. With OWIN integration, you can self-host Web API in your own process alongside other OWIN middleware, such as SignalR. For more information, see Use OWIN to Self-Host ASP.NET Web API. More Web API Improvements In addition to the features above there have been a host of other features in ASP.NET Web API, including CORS support Authentication Filters Filter Overrides Improved Unit Testability Portable ASP.NET Web API Client To learn more go to http://www.asp.net/web-api/ ASP.NET SignalR 2 ASP.NET SignalR is library for ASP.NET developers that dramatically simplifies the process of adding real-time web functionality to your applications. Real-time web functionality is the ability to have server-side code push content to connected clients instantly as it becomes available. SignalR 2.0 introduces a ton of great improvements. We’ve added support for Cross-Origin Resource Sharing (CORS) to SignalR 2.0. iOS and Android support for SignalR have also been added using the MonoTouch and MonoDroid components from the Xamarin library (for more information on how to use these additions, see the article Using Xamarin Components from the SignalR wiki). We’ve also added support for the Portable .NET Client in SignalR 2.0 and created a new self-hosting package. This change makes the setup process for SignalR much more consistent between web-hosted and self-hosted SignalR applications. To learn more go to http://www.asp.net/signalr. ASP.NET MVC 5 The ASP.NET MVC project templates integrate seamlessly with the new One ASP.NET experience and enable you to integrate all of the above ASP.NET Web API, SignalR and Identity improvements. You can also customize your MVC project and configure authentication using the One ASP.NET project creation wizard. The MVC templates have also been updated to use ASP.NET Identity and Bootstrap as well. An introductory tutorial to ASP.NET MVC 5 can be found at Getting Started with ASP.NET MVC 5. This release of ASP.NET MVC also supports several nice new MVC-specific features including: Authentication filters: These filters allow you to specify authentication logic per-action, per-controller or globally for all controllers. Attribute Routing: Attribute Routing allows you to define your routes on actions or controllers. To learn more go to http://www.asp.net/mvc Entity Framework 6 Improvements Visual Studio 2013 ships with Entity Framework 6, which bring a lot of great new features to the data access space: Async and Task<T> Support EF6’s new Async Query and Save support enables you to perform asynchronous data access and take advantage of the Task<T> support introduced in .NET 4.5 within data access scenarios.  This allows you to free up threads that might otherwise by blocked on data access requests, and enable them to be used to process other requests whilst you wait for the database engine to process operations. When the database server responds the thread will be re-queued within your ASP.NET application and execution will continue.  This enables you to easily write significantly more scalable server code. Here is an example ASP.NET WebAPI action that makes use of the new EF6 async query methods: Interception and Logging Interception and SQL logging allows you to view – or even change – every command that is sent to the database by Entity Framework. This includes a simple, human readable log – which is great for debugging – as well as some lower level building blocks that give you access to the command and results. Here is an example of wiring up the simple log to Debug in the constructor of an MVC controller: Custom Code-First Conventions The new Custom Code-First Conventions enable bulk configuration of a Code First model – reducing the amount of code you need to write and maintain. Conventions are great when your domain classes don’t match the Code First conventions. For example, the following convention configures all properties that are called ‘Key’ to be the primary key of the entity they belong to. This is different than the default Code First convention that expects Id or <type name>Id. Connection Resiliency The new Connection Resiliency feature in EF6 enables you to register an execution strategy to handle – and potentially retry – failed database operations. This is especially useful when deploying to cloud environments where dropped connections become more common as you traverse load balancers and distributed networks. EF6 includes a built-in execution strategy for SQL Azure that knows about retryable exception types and has some sensible – but overridable – defaults for the number of retries and time between retries when errors occur. Registering it is simple using the new Code-Based Configuration support: These are just some of the new features in EF6. You can visit the release notes section of the Entity Framework site for a complete list of new features. Microsoft OWIN Components Open Web Interface for .NET (OWIN) defines an open abstraction between .NET web servers and web applications, and the ASP.NET “Katana” project brings this abstraction to ASP.NET. OWIN decouples the web application from the server, making web applications host-agnostic. For example, you can host an OWIN-based web application in IIS or self-host it in a custom process. For more information about OWIN and Katana, see What's new in OWIN and Katana. Summary Today’s Visual Studio 2013, ASP.NET and Entity Framework release delivers some fantastic new features that streamline your web development lifecycle. These feature span from server framework to data access to tooling to client-side HTML development.  They also integrate some great open-source technology and contributions from our developer community.
