• Hibernate Exception Fixed By Alt+Tab

  - by Lee Theobald

  Hi all, I've got a very curious problem in Hibernate that I would like some opinions on. In my code if I do the following: Go to page A Click a link on page A to be taken to page B Click on data item on page B Exception thrown I get an error telling me: failed to lazily initialize a collection of role: XYZ, no session or session was closed Fair enough. But when I do the same thing but add an alt+tab in the middle, everything is fine. E.g. Go to page A Click a link on page A to be taken to page B Hit ALt+Tab to switch to another application Hit ALt+Tab to switch back to the web browser Click on data item on page B Everything is fine. I'm a little confused as to how switching focus from my application makes it act as I want it to. Does anyone have any light to shine on the subject? I don't think it's a locking issue as even if I do the second set of steps quicker than the first, still no error. It's a Seam application using Hibernate 3.3.2.GA & 3.4.0.GA.

• How to make Firefox extension auto install in nav bar?

  - by S M

  I'm working on a Firefox extension. I'd like to make it auto-install in the far right position on the nav bar when a user installs it. As it stands, a user has to go to View Toolbars Customize... and drag the extension to the nav bar once it's installed. I'd like to eliminate this step. The extension is here: http://madan.org/tickertool The XUL for my extension looks basically like this and it overlays browser.xul: <overlay id="my-ext-overlay" ... > <toolbarpalette id="BrowserToolbarPalette"> <toolbaritem id="my-ext-container" ... > <toolbarbutton id="my-ext-customize-image" ... /> <textbox id="my-ext-textbox" ... /> <hbox id="my-ext-buttons"> <image id="my-ext-button1" ... /> <image id="my-ext-button2" ... /> <image id="my-ext-button3" ... /> </hbox> </toolbaritem> </toolbarpalette> </overlay> I've seen code here ( https://developer.mozilla.org/en/Code_snippets/Toolbar ) that supposedly does what I'm looking for, but this code is if your extension is just a single button and I can't get it to work for me. The answer to my question is likely some modification of this code, but I haven't figured it out.

• ASP.NET MVC twitter/myspace style routing

  - by Astrofaes

  Hi guys, This is my first post after being a long-time lurker - so please be gentle :-) I have a website similar to twitter, in that people can sign up and choose a 'friendly url', so on my site they would have something like: mydomain.com/benjones I also have root level static pages such as: mydomain.com/about and of course my homepage: mydomain.com/ I'm new to ASP.NET MVC 2 (in fact I just started today) and I've set up the following routes to try and achieve the above. public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("content/{*pathInfo}"); routes.IgnoreRoute("images/{*pathInfo}"); routes.MapRoute("About", "about", new { controller = "Common", action = "About" } ); // User profile sits at root level so check for this before displaying the homepage routes.MapRoute("UserProfile", "{url}", new { controller = "User", action = "Profile", url = "" } ); routes.MapRoute("Home", "", new { controller = "Home", action = "Index", id = "" } ); } For the most part this works fine, however, my homepage is not being triggered! Essentially, when you browser to mydomain.com, it seems to trigger the User Profile route with an empty {url} parameter and so the homepage is never reached! Any ideas on how I can show the homepage?

• Problems with video conversions through the web (local host)

  - by ron-d

  Hello, I get the following errors when I attempt video format conversions called from the local host: “An invalid media type was specified” for M4V to WMV conversions. “One or more arguments are invalid” for MP4 to WMV conversions. Here are the details of the problems: I’ve written a dll in C# that accepts videos in the formats AVI, WMV, M4V and MP4 and performs the following actions: Creates a copy of the input video in WMV format . Creates a WAV file of the input video audio portion. Creates a JPG image from a frame of the input video. I attached the dll to an ASP.NET web project that performs the dll actions. When tested through the developer studio, the actions are performed as intended for all formats. When I place the web project in place to be read when the local host is called through the web browser, the following behavior takes place: WMV format: All actions performed as intended. AVI format: Creates WMV file – OK Creates JPG image – OK Creates empty WAV file – problem. M4V format: Creates empty WAV file – problem. Does not create WMV file -problem Does not create JPG file –problem Throws me the error “An invalid media type was specified” MP4 format: Creates empty WAV file – problem. Does not create WMV file -problem Does not create JPG file –problem Throws me the error “One or more arguments are invalid” When I check their security property, all the files have the same permission access parameters (when I check their security property. Can anyone guide me as to how to solve these problems when the web project is called from the local host? Thank you.

• fix needed for bug in TextField/Text

  - by Mark

  Sort of a complicated scenario - just curious if anyone else could come up with something: I have a Text control and when I scroll it and stop the scroll with the cursor over some text that has a url, the cursor doesn't revert to a hand, and also flash player starts acting as if a selection is being made from the last cursor position. So IOW a bonafide bug in flash as far as I can determine. The above probably wasn't completely clear so let me elaborate. If you grab a scrollbar thumb and start moving it up and down, you don't actually have to keep the mouse pointer on the thumb while doing so. When you stop the scroll, the mouse pointer could be outside the browser window, inside your flash application, but not currently on the scroll bar thumb, or wherever. The previously mentioned bug occurs when you stop the scroll with the mouse pointer positioned over text with an html anchor (a hyperlink). At that point the cursor enters into some state of limbo, and doesn't show the url hand pointer, and furthermore acts as if some text selection is taking place from the last cursor position prior to the scroll. So the question would be, what sort of event could I simulate in code to jolt flash out of this erroneous state it is in. And furthermore in what event could I perform this simulated event (given that for example there is no AS3 event to signal the end of a scroll.) To be clear, the Text control in question is on a canvas, and that canvas (call it A) is on another canvas which actually owns the scrollbar, and scrolling takes place by changing the scrollRect of canvas A.

• Creating and appending a big DOM with javascript - most optimized way?

  - by fenderplayer

  I use the following code to append a big dom on a mobile browser (webkit): 1. while(someIndex--) // someIndex ranges from 10 to possibly 1000 2. { 3. var html01 = ['<div class="test">', someVal,'</div>', 4. '<div><p>', someTxt.txt1, someTxt.txt2, '</p></div>', 5. // lots of html snippets interspersed with variables 6. // on average ~40 to 50 elements in this array 7. ].join(''); 8. var fragment = document.createDocumentFragment(), 9. div = fragment.appendChild(document.createElement('div')); 10. div.appendChild(jQuery(html01)[0]); 11. jQuery('#screen1').append(fragment); 12. } //end while loop 13. // similarly i create 'html02' till 'html15' to append in other screen divs Is there a better or faster way to do the above? Do you see any problems with the code? I am a little worried about line 10 where i wrap in jquery and then take it out.

• gwt seperate modules with no code sharing

  - by Code freak

  Hi, I have to make a web application using GWT. The project has a core module that'll expose a set of apis to be used by other apps; each of these app are unrelated. Each shall be loaded in a separate iframe. My idea was to compile core into core.js and each app shall have its own app1.js app2.js and so on... App1 script type="text/javascript" src="core.js" ></script> script type="text/javascript" src="app1.js" ></script> with this design, due to browser caching, each app laod only the app.js which should be smaller ~20kb in size. Making a core module is straightforward but the apps are problematic. The reason being after compilation, each app contains the entire GWT library - this substantially increases the download size of the complete webapp. Can anyone suggest a way to get aroung this problem ? I've checked similar questions on SO, but failed to find a simple working answer fr the problem. Thanks for any help.

• Appending Comment Number Anchors to Comments

  - by John

  Hello, I am using a PHP file called comments.php that has a query that enters values into a mySQL table called "comment." As the query does this, it auto-generates a field called "commentid", which is set to auto_increment in MySQL. The file also contains a loop what echoes out all comments for a given submission. It all works fine and dandy, but I want to simultaneously pull this "commentid" and turn it into a hashtag / anchor that when appended to the end of the URL makes that comment at the top of the user's browser. Someone said on another question that in order to do this one thing I should do is create an anchor on the row where the comment is being printed out. How can I do this? Thanks in advance, John The query that inserts comments into the MySQL table "comment": $query = sprintf("INSERT INTO comment VALUES (NULL, %d, %d, '%s', NULL)", $uid, $subid, $comment); mysql_query($query) or die(mysql_error()); The fields in the table "comment": commentid loginid submissionid comment datecommented The row in a loop where the comments are echoed out: echo '<td rowspan="3" class="commentname1">'.stripslashes($row["comment"]).'</td>';

How can I replicate this in ie7. Thanks, in advance

• Border of single th spreads to neighboring th when colspan set on td row below

  - by Samuel Hapak

  Having following html code: <table> <tr><th>First</th><th class='second'>Second</th><th class='third'>Third</th><th>Fourth</th></tr> <tr><td>Mike</td><td colspan=2 >John</td><td>Paul</td></tr> </table>? And following css: table { border-collapse: collapse; } td, th { border: 1px black solid; } td { border-top: none; } th { border-bottom: none; } th.second { border-bottom: 3px green solid; } th.third { } ? I would expect as result one table with 3px solid green line below the second th cell. Instead of that in Chrome, I have solid green border below both the second and the third th cell. In the firefox, results are just as expected. Is this browser bug, or my code is illegal? You can see example at http://jsfiddle.net/tt6aP/3/ PS: Try to set th.third { border-bottom: 2px solid red; } And then try to raise it to 3px. This is even more strange. Screenshots Expected: Chrome: Firefox:

• HTML table with auto-fit for some columns, fixed width for others

  - by sangil

  I'm trying to create a table adhering to the following requirements: The table width must be defined as 0 - the browser should calculate the width according to the column widths (this is to accommodate a column-resize plugin). Some columns may receive a fixed width (e.g. 50px); Columns that do not receive a fixed width, must auto-fit to the content. I have created a small example to illustrate the problem - as you can see column 3 stays at width 0 and so is not visible. HTML <table> <tr> <td class="cell header" id="header1">Header 1</td> <td class="cell header" id="header2">Header 2</td> <td class="cell header" id="header3">Header 3</td> </tr> <tr> <td class="cell">Cell 1</td> <td class="cell">Cell 2</td> <td class="cell">Very looooong content</td> </tr> </table> CSS table { table-layout: fixed; width: 100%; border: 1px solid #696969; } .cell { color: #898989; border: 1px solid #888; padding: 2px; overflow: hidden; } .header { background-color: lightsteelblue; color: black; } #header1, #header2 { width: 50px; } Is this even possible? Any help would be appreciated...

• Time to start a counter on client-side.

  - by Felipe

  Hi everybody, I'm developing an web application using asp.net mvc, and i need to do a stopwatch (chronometer) (with 30 seconds preprogrammed to start in a certain moment) on client-side using the time of the server, by the way, the client's clock can't be as the server's clock. So, i'm using Jquery to call the server by JSon and get the time, but it's very stress because each one second I call the server to get time, something like this: $(function() { GetTimeByServer(); }); function GetTimeByServer() { $.getJSon('/Home/Time', null, function(result) { if (result.SecondsPending < 30) { // call another function to start an chronometer } else { window.SetTimeout(GetTimeByServer, 1000); //call again each 1 second! } }); } It works fine, but when I have more than 3 or 4 call like this, the browser slowly but works! I'd like to know, how improve more performace in client side, or if is there any way to do this... is there any way to client listen the server like a "socket" to know if the chronometer should start... PS: Sorry for my english! thanks Cheers

• Connect to Facebook with Javascript Client Library using Adobe AIR

  I'm having an issue connecting to Facebook through the Javascript Client Library in Adobe AIR. It works fine in the browser but in Adobe AIR it seems to not be able to find the Facebook functions. Here is some code I copied from the Facebook website: (Oh and I have the xd_receiver.htm file in the correct path too) <textarea style="width: 1000px; height: 300px;" id="_traceTextBox"> </textarea> <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script> // var api = FB.Facebook.apiClient; // require user to login api.requireLogin(function(exception){ FB.FBDebug.logLevel=1; FB.FBDebug.dump("Current user id is " + api.get_session().uid); // Get friends list //5-14-09: this code below is broken, correct code follows //api.friends_get(null, function(result){ // Debug.dump(result, 'friendsResult from non-batch execution '); // }); api.friends_get(new Array(), function(result, exception){ FB.FBDebug.dump(result, 'friendsResult from non-batch execution '); }); }); }); //]]> </script>

• Mimic Coldfusion's debug output in PHP?

  - by TekiusFanatikus

  I'm trying to mimic Coldfusion's debug output in PHP. Here's an example of what it looks like (ie. Execution Time section): I've turned to XDebug. Ideally, the exception stack error output would be what I'd be looking for. However, it only shows up when an exception occurs. I also tried something like (in our CMS-ish app) this (original question here): $content.= "<?php xdebug_start_trace('e:/xdebug/trace');?>"; $content.= "<?php require('".$page['file_'.LG]."'); ?>"; $content.= "<?php xdebug_stop_trace();?>"; ... $content.= "<?php echo readfile('e:/xdebug/trace.xt');?>"; However, I get an insane, browser crashing HTML table dropped at the bottom of page. Not very efficient. My php.ini config: xdebug.trace_format = 2 xdebug.collect_vars = 1 xdebug.collect_params = 4 xdebug.dump_globals = 1 xdebug.dump.SERVER = 'REQUEST_URI' xdebug.show_local_vars = 1 xdebug.show_mem_delta = 1 I'm just wondering if someone has already done something similar?

• PHP - dynamic page via subdomain

  - by Phil Jackson

  Hi, im creating profile pages based on a subdomains using the wildcard DNS setting. Problem being, if the subdomain is incorrect, I want it to redirect to the same page but without the subdomain infront ie; if ( preg_match('/^(www\.)?([^.]+)\.domainname\.co.uk$/', $_SERVER['HTTP_HOST'], $match)) { $DISPLAY_NAME = $match[2]; $query = "SELECT * FROM `" . ACCOUNT_TABLE . "` WHERE DISPLAY_NAME = '$DISPLAY_NAME' AND ACCOUNT_TYPE = 'premium_account'"; $q = mysql_query( $query, $CON ) or die( "_error_" . mysql_error() ); if( mysql_num_rows( $q ) != 0 ) { }else{ mysql_close( $CON ); header("location: http://www.domainname.co.uk"); exit; } } I get a browser error: Firefox has detected that the server is redirecting the request for this address in a way that will never complete. I think its because when using header("location: http://www.domainname.co.uk"); it still puts the sub domain infront i.e. ; header("location: http://www.sub.domainname.co.uk"); Does anyone know how to sort this and/or what is the problem.

• Initializing Disqus comments in hidden element causes issue in FF 14.0.1

  - by Bazze

  This issue appears only in Firefox 14.0.1 (well I couldn't reproduce it in any other browser). If you put the code for Disqus comments inside an element that is hidden and wait until everything is fully loaded and then display the element using JavaScript, the comment box nor comments will show up. However if you resize the window, it'll show up immediately. It's working fine in latest version of Google Chrome and Safari though. What's causing this and how to fix it? Sample code to reproduce: <div id="test" style="display:none;"> <div id="disqus_thread"></div> <script type="text/javascript"> /* * * CONFIGURATION VARIABLES: EDIT BEFORE PASTING INTO YOUR WEBPAGE * * */ var disqus_shortname = 'onlinefunctions'; // required: replace example with your forum shortname /* * * DON'T EDIT BELOW THIS LINE * * */ (function() { var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true; dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq); })(); </script> <noscript>Please enable JavaScript to view the <a href="http://disqus.com/?ref_noscript">comments powered by Disqus.</a></noscript> <a href="http://disqus.com" class="dsq-brlink">comments powered by <span class="logo-disqus">Disqus</span></a> </div> <a href="#" onclick="document.getElementById('test').style.display = 'block'">show</a> I could post a link to a live example but I'm not sure about the policy of posting links here on Stack Overflow.

• What do you call the highlight as you hover over an OPTION in a SELECT, and how can I "un"highlight

  - by devils-avacado

  I'm working on dropdowns in IE6 (SELECT with OPTIONs as children). I'm experiencing the problem where, in IE6, dropdown menus are truncated to the width of the SELECT element. I used this jquery to fix it: var css_expanded = { 'width' : 'auto', 'position' : 'absolute', 'left' : '564px', 'top' : '393px' } var css_off = { 'width' : '190px', 'position' : 'relative', 'left' : '0', 'top' : '0' } if($.browser.msie) { $('#dropdown') .bind('mouseover', function() { $(this).css(css_expanded); }) .bind('click', function() { $(this).toggleClass('clicked'); }) .bind('mouseout', function() { if (!$(this).hasClass('clicked')) { $(this).css(css_off); } }) .bind('change blur focusout', function() { $(this).removeClass('clicked') .css(css_off) }); }; It works fine in IE7+8, but in IE6, if the user clicks on a SELECT and does not click any OPTION but instead clicks somewhere else on the page, outside the SELECT (blur), the SELECT still has a "highlight", the same as if they were hovering over an OPTION with my mouse (in my case, a blue color), and the width is not restored until the user clicks outside the SELECT a second time. In other browsers, blur causes every OPTION to not be highlighted. Using JS, how can I de-highlight an option after the dropdown has lost focus.

• How to protect a form HTML/PHP with JS callback to AS3

  - by Jk_

  Hi guys, I'm developing a Flash website (as3) where I need to be able to upload directly to YouTube by using the DATA API. However in order to do so, I had to use a proper HTML form on top of my flash object. Why? Because of the Browser Based Upload restictions. I first hide the form using JQuery and with a little CSS the form is display just where I want it. Within flash I use ExternalInterface.call() to show/hide the form when I need it! ExternalInterface.call("YTUploader.showIt"); The upload process is working great my only problem is that the form can be displayed easily... You just need a tool like firebug and you can use the form wherever you want on my flash app. So I was wandering which will be the best way to 'protect' this form or the best way to limit its access. Any advices will be appreciated. Thanks for your time. Jk.

• Do I want an embedded web-server, or what?

  - by mawg

  So, someone want me to hack some code for him. He has a 42" TFT display on which he will display some application/business related data. However, 75% of the screen real estate is unused, so he wants to fill it with "TV/adverts/flash/you know, that kind of thing... web based....". Any advice? Do I want an embedded web-server? If so, which? (he wants free & open source, or as cheap as possible) Do I display it in a browser? (duh! probably, dude) But I don't want/need a menu, address bar, toolbar, etc - it should be full screen (does that mean "kiosk mode"?). Sorry, folks, the requirements are not clear, but I hope that you can guess what he probably means (he is not very techie). How should I proceed with this? Thanks.

• PowerPoint PlugIn does not read defaults from .dll.config file

  - by Nick T

  I'm working on a very simple PowerPoint plugin, and I'm quite a bit stumped. In my settings.settings file, I have configured a setting "StartPath", which references where the PowerPoint plugin will navigate to using a Browser component. After I compile the application, and run the installer generated by the Setup project, the application is installed and uses the default value in the settings file. However, if I edit the application.dll.config file, the plugin still uses the old values. How can I set things up such that the plugin references the .dll.config file and not its default settings? The code to access the settings is listed below, including the other variants I have tried: //Attempt 1 string location = MyApplication.Properties.Settings.Default.StartPath; //Attempt 2 string location = ConfigurationManager.AppSettings["StartPath"]; //Attempt 3: Configuration element is inaccessible due to its protection level string applicationName = Environment.GetCommandLineArgs()[0] + ".exe"; string exePath = System.IO.Path.Combine(Environment.CurrentDirectory, applicationName); Configuration config = ConfigurationManager.OpenExeConfiguration(exePath); string location = config.AppSettings["StartPath"];

• How to report progress of a JavaScript function?

  - by LambyPie

  I have a JavaScript function which is quite long and performs a number of tasks, I would like to report progress to the user by updating the contents of a SPAN element with a message as I go. I tried adding document.getElementById('spnProgress').innerText = ... statements throughout the function code. However, whilst the function is executing the UI will not update and so you only ever see the last message written to the SPAN which is not very helpful. My current solution is to break the task up into a number of functions, at the end of each I set the SPAN message and then "trigger" the next one with a window.setTimeout call with a very short delay (say 10ms). This yields control and allows the browser to repaint the SPAN with the updated message before starting the next step. However I find this very messy and difficult to follow the code, I'm thinking there must be a better way. Does anyone have any suggestions? Is there any way to force the SPAN to repaint without having to leave the context of the function? Thanks

• S.redirectTo leads always to a blank screen

  - by Jaime Ocampo

  I am now playing a little bit with lift (2.8.0), and all the features in LiftRules work as intended. But I haven't been able to use S.redirectTo at all. I always ends with a blank screen, no matter what. No error messages at all! As an example, I have the following form: ... <lift:logIn.logInForm form="post"> <p><login:name /></p> <p><login:password /></p> <p><login:submit /></p> </lift:logIn.logInForm> ... And the code is: object LogIn extends helper.LogHelper { ... def logInForm(in: NodeSeq): NodeSeq = { var name = "" var password = "" def login() = { logger.info("name: " + name) logger.info("password: " + password) if (name == "test1") S.redirectTo("/example") if (name == "test2") S.redirectTo("/example.html") if (name == "test3") S.redirectTo("example.html") S.redirectTo("/") } bind("login", in, "name" -> SHtml.text(name, name = _), "password" -> SHtml.password(password, password = _), "submit" -> SHtml.submit("Login", login)) } } The method 'login' is invoked, I can check that in the log information. But as I said, no matter which name I enter, I always end with a blank screen, although 'examples.html' is available when being accessed directly in the browser. How should I invoke S.redirectoTo in order to navigate to 'examples.html'? Also, why don't I receive an error message (I am logging at a debug level)? I think all the configuration in Boot is correct, since all LitRules examples (statelessRewrite, dispatch, viewDispatch, snippets) work fine.
