  • What are possible designs for the DCI architecture?

    - by Gabriel Šcerbák
    What are possibles designs for implementation of the DCI (data, contexts, interactions) architecture in different OOP languages? I thought of Policy based design (Andrei Alexandrescu) for C++, DI and AOP for Java. However, I also thought about using State design pattern for representing roles and some sort of Template method for the interactions... What are the other possibilities?

  • Greasemonkey is getting an empty document.body on select Google pages.

    - by Brock Adams
    Hi, I have a Greasemonkey script that processes Google search results. But it's failing in a few instances, when xpath searches (and document body) appear to be empty. Running the code in Firebug's console works every time. It only fails in a Greasemonkey script. Greasemonkey sees an empty document.body. I've boiled the problem down to a test, greasemonkey script, below. I'm using Firefox 3.5.9 and Greasemonkey 0.8.20100408.6 (but earlier versions had the same problem). Problem: Greasemonkey sees an empty document.body. Recipe to Duplicate: Install the Greasemonkey script. Open a new tab or window. Navigate to Google.com (http://www.google.com/). Search on a simple term like "cats". Check Firefox's Error console (Ctrl-shift-J) or Firebug's console. The script will report that document body is empty. Hit refresh. The script will show a good result (document body found). Note that the failure only reliably appears on Google results obtained this way, and on a new tab/window. Turn javascript off globally (javascript.enabled set to false in about:config). Repeat steps 2 thru 5. Only now the Greasemonkey script will work. It seems that Google javascript is killing the DOM tree for greasemonkey, somehow. I've tried a time-delayed retest and even a programmatic refresh; the script still fails to see the document body. Test Script: // // ==UserScript== // @name TROUBLESHOOTING 2 snippets // @namespace http://www.google.com/ // @description For code that has funky misfires and defies standard debugging. // @include http://*/* // ==/UserScript== // function LocalMain (sTitle) { var sUserMessage = ''; //var sRawHtml = unsafeWindow.document.body.innerHTML; //-- unsafeWindow makes no difference. var sRawHtml = document.body.innerHTML; if (sRawHtml) { sRawHtml = sRawHtml.replace (/^\s\s*/, ''). substr (0, 60); sUserMessage = sTitle + ', Doc body = ' + sRawHtml + ' ...'; } else { sUserMessage = sTitle + ', Document body seems empty!'; } if (typeof (console) != "undefined") { console.log (sUserMessage); } else { if (typeof (GM_log) != "undefined") GM_log (sUserMessage); else if (!sRawHtml) alert (sUserMessage); } } LocalMain ('Preload'); window.addEventListener ("load", function() {LocalMain ('After load');}, false);

  • How can I emulate the ASP.NET Ajax UpdatePanel when using ASP.NET MVC?

    - by Gary McGill
    In "traditional" ASP.NET (Web Forms), the UpdatePanel control lets you do a partial refresh of a part of a page. You don't need to write much code to hook this up. What's the equivalent in ASP.NET MVC? I'm guessing I'd need to use a partial view for the bit that I want to update, then on the client side retrieve that HTML and pump it into the innerHtml of the correct DIV? A tutorial/example would be helpful...

  • Partial view postback from a standard Html form with MVC

    - by fearofawhackplanet
    I have a file upload button on my MVC view. After the file is uploaded, my FileList partial view on the page should refresh. I tried to upload with Ajax.BeginForm(), but have discovered that Ajax will not submit file data. I've got the file upload working now by using the jQuery Form plugin, which lets you ajaxify the normal Html.BeginForm() submit method. Is is still possible to trigger the partial page update using this method?

  • Get invalid user input with a Spring typeMismatch error

    - by TimmyJ
    I've implemented a ReloadableResourceBundleMessageSource in my Spring MVC application which I use to display prettier error messages for binding exceptions. The problem I'm having is that, due to a company policy, these errors must be displayed in the following format: [inputData] is not a valid [fieldName]. The field name is accessible by default in my message properties file (as the {0} argument), but I can't figure out a way to display the invalid user input. Is this possible?

    We have Youtube videos on a site and want to detect if it is likely that they will not be able to view them due to (mostly likely) company policy or otherwise.

I cant even think of a 'nice hack'

  • Saving Variables In An ASP Page

    - by Or Betzalel
    I'm trying to convert a game I made (WindowsFormApplication) to an ASP Page. My Problem is that I have a lot "private" variables in my WindowFormApplication and those variables are important for the game. But when after I Declare all my variables (in my Page_Load), they turn null no matter what I do(click a button, refresh the page). Is there anyway to save my variables between buttons (other than Session, because I'd have to create like 6 more sessions)

  • Dynamic content doesn't work when loaded with ajax

    - by Wurlitzer
    I'm trying to load some dynamic content after the user has logged in, using $.ajax, like so: $.ajax({ url: "functions.php", type: "GET", data: login_info, datatype: 'html', async: false, success: function (response) { $('#main').html(response); } }); The problem is, that some events don't work, when loaded this way. I fixed the buttons with the .live() method, but a sortable list for example, doesn't work. How can I somehow refresh the DOM, and let jquery know of these new added elements? Thanks!

  • TFS 2008 checks out code automatically on edit

    - by Jangwenyi
    I am working on a Visual Studio 2008 project that is already added to TFS server. I am not sure which settings and policies have been configured for the TFS (this is done by a separate dept, not developers) Every time I make an edit to a code file , the file is checked out automatically (without explicitly checking out the code file myself) Please help me locate this setting or policy because it is not very useful at the moment. Sometime you want to make a local change to try out something, and not necessarily check out the code....

  • Validation and Firefox's input caching

    - by Chris Simpson
    When you refresh/reload a page or use the back button, Firefox is kind enough to repopulate your inputs with what was entered before you navigated away. Though this is a nice feature it does not trigger my jquery validation and the unsaved changes warning I add to my pages. Is there a way to either disable this feature in Firefox (without renaming every control every time) or capture the firefox events?

  • MooTools event listener disappears after element.innerHTML is changed

    - by acoder
    Hi everyone, I am trying to achieve this task using MooTools. Description: I attached an event listener to "myButton" link. A click on this link initiates an AJAX request and updates "myDiv" content based on the response text. During this request a POST variable is being sent to "button.php", but it's not used at the moment.. (i wish to use it later) OK, as a result, "myDiv" gets exactly the same link with the same ID (myButton) + a random number, so that we could see that each click generates a new number. The problem: After the first click on "myButton", "myDiv" updates correctly, showing a random number. When I click "myButton" for the second time (this time in newly updated div), the div does not refresh anymore. Please note that I need "myButton" to be inside "myDiv", and "myDiv" must be updated (refreshed) after each click without having to refresh the entire page. Can somebody show me how to achieve this task based on this simplified code example? index.html <html> <head> <script type="text/javascript" src="mootools-1.2.4-core-nc.js"></script> <script> window.addEvent('domready', function() { $('myButton').addEvent('click', function(e) { e.stop(); var myRequest = new Request({ method: 'post', url: 'button.php', data: { action : 'test' }, onRequest: function() { $('myDiv').innerHTML = '<img src="images/loading.gif" />'; }, onComplete: function(response) { $('myDiv').innerHTML = response; } }); myRequest.send(); $('myButton').removeEvent('click'); }); }); </script> </head> <body> <div id="myDiv"> <a id="myButton" href="#">Button</a> </div> </body> </html> button.php <a id="myButton" href="#">Button</a> clicked <?php echo rand(1,100); ?>
