  • How do you detect when the Flowplayer has started playing the video?

    - by Alex
    Hi. I'm using the Flowplayer Flash video player to play MP4 videos inside an AnythingSlider. I need to detect when the user has clicked the start button on the video so to stop the slideshow and allow the user to view the video. I've tried using this code just to get an alert box but it doesn't do anything (the code is at the end of the page, before the closing </body> tag): <script type="text/javascript"> $f("player","global/js/flowplayer/flowplayer-3.1.5.swf",{ onStart: function(clip) { alert('player started'); } }); </script> The Flowplayer is implemented as part of the html5media library, which automatically detects whether the browser can handle the <video> tag; if not, it replaces the anchor tag below with the Flowplayer: <video id="vid" width="372" height="209" poster="global/vid/bbq-poster.jpg" controls preload> <source id="videoSource" src="global/vid/BBQ_Festival.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' onerror="fallback(this.parentNode)" ></source> <a href="global/vid/BBQ_Festival.mp4" style="display:block;width:372px;height:209px; padding-left:5px; " id="player"> </a> </video> So the $f() function call is in a JavaScript block at the end of the page, to give the player a chance to load correctly. What am I doing wrong? Thanks.

  • IE 8 issue where window.close() is not occuring after winword.exe is fired to print a document

    - by Dave
    In my web application, a popup page is called using window.open javascript. There is a Print button on the page that has an onclick event that calls a printchecks() function. The code in the printchecks() function is function printchecks(){ window.print(); window.close(); } Issue is that the window.print brings up the printer dialog fine and then you select a printer. The page is actually then printed and is a reference to an rtf document that opens in winword.exe behind the scenes. For some reason in IE 8, the window.close() does not occur. This worked in IE 7. In both cases, WINWORD.EXE process appears to run in the background after the page is printed but in the case of IE 8, control is not give back to that popup page until the WINWORD.EXE process dies which takes a minute or so. I am thinking that becasue control is not being sent back to the page in IE 8, the page is not closed automatically. You can close the page after control is given back after the minute or so. This does happen in IE on both Windows XP and Windows 7. Any ideas if there is a setting in IE 8 or some other reason this may be occuring?

  • Extjs - Loading Grid when call

    - by Oxi
    I have form and grid. the user must enter data in form fields then display related records in the grid. I want to implement a search form, e.g: user will type the name and gender of the student, then will get a grid of all students have the same name and gender. So, I use ajax to send form fields value to PHP and then creat a json_encode wich will be used in grid store. I am really not sure if my idea is good. But I haven't found another way to do that. The problem is when I set autoLoad to true in the store, the grid automatically filled with all data - not just what I asked for - So, I understand that I have to set autoLoad to false, but then the result not shown in the grid even it returned successfully in the firebug! I don't know what to do. My View: { xtype: 'panel', layout: "fit", id: 'searchResult', flex: 7, title: '<div style="text-align:center;"/>SearchResultGrid</div>', items: [ { xtype: 'gridpanel', store: 'advSearchStore', id: 'AdvSearch-grid', columns: [ { xtype: 'gridcolumn', dataIndex: 'name', align: 'right', text: 'name' }, { xtype: 'gridcolumn', dataIndex: 'gender', align: 'right', text: 'gender' } ], viewConfig: { id : 'Arr' ,emptyText: 'noResult' }, requires: ['MyApp.PrintSave_toolbar'], dockedItems: [ { xtype: 'PrintSave_tb', dock: 'bottom', } ] } ] }, My Store and Model: Ext.define('AdvSearchPost', { extend: 'Ext.data.Model', proxy: { type: 'ajax', url: 'AdvSearch.php', reader: { type: 'json', root: 'Arr', totalProperty: 'totalCount' } }, fields: [ { name: 'name'}, { name: 'type_and_cargo'} ] }); Ext.create('Ext.data.Store', { pageSize: 10, autoLoad: false, model: 'AdvSearchPost', storeId: 'AdvSearchPost' });

  • How to structure the tables of a very simple blog in MySQL?

    - by Programmer
    I want to add a very simple blog feature on one of my existing LAMP sites. It would be tied to a user's existing profile, and they would be able to simply input a title and a body for each post in their blog, and the date would be automatically set upon submission. They would be allowed to edit and delete any blog post and title at any time. The blog would be displayed from most recent to oldest, perhaps 20 posts to a page, with proper pagination above that. Other users would be able to leave comments on each post, which the blog owner would be allowed to delete, but not pre-moderate. That's basically it. Like I said, very simple. How should I structure the MySQL tables for this? I'm assuming that since there will be blog posts and comments, I would need a separate table for each, is that correct? But then what columns would I need in each table, what data structures should I use, and how should I link the two tables together (e.g. any foreign keys)? I could not find any tutorials for something like this, and what I'm looking to do is really offer my users the simplest version of a blog possible. No tags, no moderation, no images, no fancy formatting, etc. Just a simple diary-type, pure-text blog with commenting by other users.

  • App-Engine Parse a UrlFetch UTF-8 encoded stream

    - by Davidrd91
    I am trying to parse an XML from a URL using the xml.sax parser. I know there are other libraries to use but coming from Java this is the one I am most familiar with and seems the least complicated to me. The code I'm using to parse is as follows: parser = xml.sax.make_parser() handler = MangaHandler() parser.setContentHandler(handler) url = urlfetch.Fetch('http://www.mangapanda.com/alphabetical', allow_truncated = False, follow_redirects = False, deadline = False) xml.sax.parseString(url.content, handler) This returns a SaxException (invalid token) once the parser reaches the first & sign: SAXParseException: <unknown>:582:34: not well-formed (invalid token) Because urlfetch returns a string and not a stream I cannot use the parse() (which only works with streams) and am left to use parseString() instead. To see if parsing as a stream would fix this I tried: parser.parse(io.StringIO(url.content).encode('utf-8')) but this returns: TypeError: initial_value must be unicode or None, not str I have also tried to use the urllib2 libraries which do return a stream instead of urlfetch but the file is too large and is automatically truncated, leaving me with missing data. Any Sort of work-around for this would be greatly appreciated as I've spent days getting around one obstacle just to be stopped by another.

  • Changing <object> height and width works in Chrome but not Firefox or IE. Why?

    - by Michael Hopkins
    I am making a site with two Youtube videos. These videos use the raw embed code from Youtube. The site's design doesn't work with any of the default Youtube sizes, so I am writing code to automatically resize the video. Here is my code. There will never be more than these two tags on the page, otherwise I'd do a better job selecting the videos. <script language='JavaScript' type='text/javascript'> var x=document.getElementsByTagName('object'); x.[0].width='350'; x.[0].height='350'; x.[1].width='350'; x.[1].height='350'; </script> For reference, here's a sample default Youtube embed that the code might alter: <object width="480" height="385"> <param name="movie" value="http://www.youtube-nocookie.com/v/zSgiXGELjbc&hl=en_US&fs=1&rel=0"></param> <param name="allowFullScreen" value="true"></param> <param name="allowscriptaccess" value="always"></param> <embed src="http://www.youtube-nocookie.com/v/zSgiXGELjbc&hl=en_US&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed> </object> In Chrome, the video players sit perfectly in a 350x350 box. In IE and FF (latest versions), the videos are the unchanged, normal size. I cannot find anything in Google that explans why this won't work. I have tried using setattribute, for loops, adjusting both and , single-quotes and double-quotes, etc. Any ideas what is going wrong?

  • G++ Multi-platform memory leak detection tool

    - by indyK1ng
    Does anyone know where I can find a memory memory leak detection tool for C++ which can be either run in a command line or as an Eclipse plug-in in Windows and Linux. I would like it to be easy to use. Preferably one that doesn't overwrite new(), delete(), malloc() or free(). Something like GDB if its gonna be in the command line, but I don't remember that being used for detecting memory leaks. If there is a unit testing framework which does this automatically, that would be great. This question is similar to other questions (such as http://stackoverflow.com/questions/283726/memory-leak-detection-under-windows-for-gnu-c-c ) however I feel it is different because those ask for windows specific solutions or have solutions which I would rather avoid. I feel I am looking for something a bit more specific here. Suggestions don't have to fulfill all requirements, but as many as possible would be nice. Thanks. EDIT: Since this has come up, by "overwrite" I mean anything which requires me to #include a library or which otherwise changes how C++ compiles my code, if it does this at run time so that running the code in a different environment won't affect anything that would be great. Also, unfortunately, I don't have a Mac, so any suggestions for that are unhelpful, but thank you for trying. My desktop runs Windows (I have Linux installed but my dual monitors don't work with it) and I'd rather not run Linux in a VM, although that is certainly an option. My laptop runs Linux, so I can use that tool on there, although I would definitely prefer sticking to my desktop as the screen space is excellent for keeping all of the design documentation and requirements in view without having to move too much around on the desktop. NOTE: While I may try answers, I won't mark one as accepted until I have tried the suggestion and it is satisfactory. EDIT2: I'm not worried about the cross-platform compatibility of my code, it's a command line application using just the C++ libraries.

  • Visual Studio identical token highlighting

    - by dsteinweg
    I coded a Mancala game in Java for a college class this past spring, and I used the Eclipse IDE to write it. One of the great (and fairly simple) visual aids in Eclipse is if you select a particular token, say a declared variable, then the IDE will automatically highlight all other references to that token on your screen. Notepad++, my preferred Notepad replacement, also does this. Another neat and similar feature in Eclipse was the vertical "error bar" to the right of your code (not sure what to call it). It display little red boxes for all of the syntax errors in your document, yellow boxes for warnings like "variable declared but not used", and if you select a word, boxes appear in the bar for each occurance of the word in the document. A screenshot of these features in action: After a half hour of searching, I've determined that Visual Studio cannot do this on its own, so my question is: does anyone know of any add-ins for 2005 or 2008 that can provide either one of the aforementioned features? Being able to highlight the current line your cursor is on would be nice too. I believe the add-in ReSharper can do this, but I'd prefer to use a free add-in rather than purchase one.

  • Generic callbacks

    - by bobobobo
    Extends So, I'm trying to learn template metaprogramming better and I figure this is a good exercise for it. I'm trying to write code that can callback a function with any number of arguments I like passed to it. // First function to call int add( int x, int y ) ; // Second function to call double square( double x ) ; // Third func to call void go() ; The callback creation code should look like: // Write a callback object that // will be executed after 42ms for "add" Callback<int, int, int> c1 ; c1.func = add ; c1.args.push_back( 2 ); // these are the 2 args c1.args.push_back( 5 ); // to pass to the "add" function // when it is called Callback<double, double> c2 ; c2.func = square ; c2.args.push_back( 52.2 ) ; What I'm thinking is, using template metaprogramming I want to be able to declare callbacks like, write a struct like this (please keep in mind this is VERY PSEUDOcode) <TEMPLATING ACTION <<ANY NUMBER OF TYPES GO HERE>> > struct Callback { double execTime ; // when to execute TYPE1 (*func)( TYPE2 a, TYPE3 b ) ; void* argList ; // a stored list of arguments // to plug in when it is time to call __func__ } ; So for when called with Callback<int, int, int> c1 ; You would automatically get constructed for you by < HARDCORE TEMPLATING ACTION > a struct like struct Callback { double execTime ; // when to execute int (*func)( int a, int b ) ; void* argList ; // this would still be void*, // but I somehow need to remember // the types of the args.. } ; Any pointers in the right direction to get started on writing this?

  • reload parent from within iframe

    - by Lauren
    I can't seem to reload the parent page from within an iframe... I've looked around at similar questions' answers but nothing has worked so far. The iframe I'm working with is here http://www.avaline.com/ R3000_3 once you log in, then hit the "order sample" button, and then hit "here" where it says "Your Third Party Shipper Numbers (To enter one, click here.)". I tried using javascript statements window.top.location.reload(),window.parent.location.reload(),window.parent.location.href=window.parent.location.href but none of those worked in FF 3.6 so I didn't move on to the other browsers although I am shooting for a cross-browser solution. I put the one-line javascript statements inside setTimeout("statement",2000) so people could read the content of the iframe (You have updated your shipper number(s). The page should refresh automatically. If not, please refresh and return to "order sample.") before the redirect happens, but that shouldn't affect the execution of the statements... I wish I could test and debug the statements with the Firebug console from within the Iframe but there doesn't seem to be any great way to test this out.

  • Safari doesn't detect my Extension Certificate

    - by Questor
    Hello, all! I have registered for the Safari Development Program and have a valid Apple ID. I've followed all the steps given by Apple. The problem is that Windows XP (Service Pack 2) does not recognize the command 'certreq', whereas the instructions said it would work on any Windows machine. However, the command 'certreq' was working on Windows Vista on the machine of my co-worker's, I downloaded the certificate (the .cer file) and installed it and Safari detected it. However, I don't have Windows Vista. I installed Windows 7 now on my machine, the command 'certreq' works and I have the Safari Extension Certificate (the .cer file) but when I open Safari's Extension Builder, my certificate does not appear there. I entered mmc in Start -- Run and checked if the certificate was installed there. It was in the 'Other People' but not in 'Personal'. Even on Internet Explorer 7+, when I go to Tools -- Internet Options -- Content (Tab) -- Certificates, the certificate is not there in the Personal tab, (WHEREAS IT GOT INSTALLED IN THE PERSONAL FOLDER AUTOMATICALLY IN WINDOWS VISTA). I tried importing the certificate (the .cer file) into the Peronal folder, the import is successful but still neither does it appear in the personal folder nor does Safari recognize/detect it when I go to the Extension Builder. ANY HELP?! I need to make an extension for my office project and the deadline is approaching. I really need to get it done. Thanks a million in anticipation.

  • Hide a single content block from search engines?

    - by jonas
    A header is automatically added on top of each content URL, but its not relevant for search and messing up the all the results beeing the first line of every page (in the code its the last line but visually its the first, which google is able to notice) Solution1: You could put the header (content to exculde from google searches) in an iframe with a static url domain.com/header.html and a <meta name="robots" content="noindex" /> ? - are there takeoffs of this solution? Solution2: You could deliver it conditionally by apache mod rewrite, php or javascript -takeoff(?): google does not like it? will google ever try pages with a standard users's useragent and compare? -takeoff: The hidden content will be missing in the google cache version as well... example: add-header.php: <?php $path = $_GET['path']; echo file_get_contents($_SERVER["DOCUMENT_ROOT"].$path); ?> apache virtual host config: RewriteCond %{HTTP_USER_AGENT} !.*spider.* [NC] RewriteCond %{HTTP_USER_AGENT} !Yahoo.* [NC] RewriteCond %{HTTP_USER_AGENT} !Bing.* [NC] RewriteCond %{HTTP_USER_AGENT} !Yandex.* [NC] RewriteCond %{HTTP_USER_AGENT} !Baidu.* [NC] RewriteCond %{HTTP_USER_AGENT} !.*bot.* [NC] RewriteCond %{SCRIPT_FILENAME} \.htm$ [NC,OR] RewriteCond %{SCRIPT_FILENAME} \.html$ [NC,OR] RewriteCond %{SCRIPT_FILENAME} \.php$ [NC] RewriteRule ^(.*)$ /var/www/add-header.php?path=%1 [L]

  • Subclassing ViewPager Breaks Animation

    - by Ryan Thomas
    In my Android application I have an activity which uses a view pager to display 4+ pages (Fragments). I implemented buttons on each screen that move between pages by calling: pager.setCurrentItem(position, true); The view pager and fragments are all working as I desired. I then began looking for a solution to disable user swiping between pages so that the transition between pages in handled by the buttons only. The solution I found was mentioned in a few stackoverflow articles as well as This Blog that suggest subclassing the view pager to intercept touch events to disable swiping. I followed those examples by subclassing the view pager class as follows: public class ViewPager extends android.support.v4.view.ViewPager { private boolean enabled; public ViewPager(Context context, AttributeSet attrs) { super(context, attrs); this.enabled = true; } @Override public boolean onTouchEvent(MotionEvent event) { if (this.enabled) { return super.onTouchEvent(event); } return false; } @Override public boolean onInterceptTouchEvent(MotionEvent event) { if (this.enabled) { return super.onInterceptTouchEvent(event); } return false; } public void setSwipingEnabled(boolean enabled) { this.enabled = enabled; } } Using the subclassed view pager and calling setSwipingEnabled(false) works as was desired. The user can no longer move between pages with swipe gestures and I can still move between pages via button clicks by calling setCurrentItem(int position, boolean smoothScroll). However using the subclass breaks the animation between pages. When I call setCurrentItem(position, true) with android.support.v4.view.ViewPager I get very clean scrolling animations between pages. When I make the same call using the subclass the screen has a very brief 'flash' and then automatically draws the new page. I would like to know how to fix the animation while retaining the ability to disable user swiping between pages. I greatly appreciate any help with this. Let me know if you need any additional information. So far I have tested using a Samsung device running 2.3.5 and an AVD emulator targeting Android 2.3.3.

  • How to install a desktop shortcut (to a batch file) from a WiX-based installer that has "Run as Admi

    - by arathorn
    I'm installing a desktop shortcut (to a batch file) from a WiX-based installer -- how do I automatically configure this shortcut with the "Run as Administrator" setting enabled? The target OS is Windows Server 2008 R2, and the installer is running with elevated priveleges. Update: Thanks to the link provided by @Anders, I was able to get this working. I needed to do this in a C# CustomAction, so here is the C# version of the code: namespace CustomAction1 { public class CustomAction1 { public bool MakeShortcutElevated(string file_) { if (!System.IO.File.Exists(file_)) { return false; } IPersistFile pf = new ShellLink() as IPersistFile; if (pf == null) { return false; } pf.Load(file_, 2 /* STGM_READWRITE */); IShellLinkDataList sldl = pf as IShellLinkDataList; if (sldl == null) { return false; } uint dwFlags; sldl.GetFlags(out dwFlags); sldl.SetFlags(dwFlags | 0x00002000 /* SLDF_RUNAS_USER */); pf.Save(null, true); return true; } } [ComImport(), Guid("00021401-0000-0000-C000-000000000046")] public class ShellLink { } [ComImport(), InterfaceType(ComInterfaceType.InterfaceIsIUnknown), Guid("45e2b4ae-b1c3-11d0-b92f-00a0c90312e1")] interface IShellLinkDataList { void GetFlags(out uint pdwFlags); void SetFlags(uint dwFlags); } }

  • How is it legal to reference an undefined type inside a structure?

    - by paxdiablo
    As part of answering another question, I came across a piece of code like this, which gcc compiles without complaint. typedef struct { struct xyz *z; } xyz; int main (void) { return 0; } This is the means I've always used to construct types that point to themselves (e.g., linked lists) but I've always thought you had to name the struct so you could use self-reference. In other words, you couldn't use xyz *z within the structure because the typedef is not yet complete at that point. But this particular sample does not name the structure and it still compiles. I thought originally there was some black magic going on in the compiler that automatically translated the above code because the structure and typedef names were the same. But this little beauty works as well: typedef struct { struct NOTHING_LIKE_xyz *z; } xyz; What am I missing here? This seems a clear violation since there is no struct NOTHING_LIKE_xyz type defined anywhere. When I change it from a pointer to an actual type, I get the expected error: typedef struct { struct NOTHING_LIKE_xyz z; } xyz; qqq.c:2: error: field `z' has incomplete type Also, when I remove the struct, I get an error (parse error before "NOTHING ...). Is this allowed in ISO C?

  • How to generate lots of redundant ajax elements like checkboxes and pulldowns in Django?

    - by iJames
    Hello folks. I've been getting lots of answers from stackoverflow now that I'm in Django just be searching. Now I hope my question will also create some value for everybody. In choosing Django, I was hoping there was some similar mechanism to the way you can do partials in ROR. This was going to help me in two ways. One was in generating repeating indexed forms or form elements, and also in rendering only a piece of the page on the round trip. I've done a little bit of that by using taconite with a simple URL click but now I'm trying to get more advanced. This will focus on the form issue which boils down to how to iterate over a secondary object. If I have a list of photo instances, each of which has a couple of parameters, let's say a size and a quantity. I want to generate form elements for each photo instance separately. But then I have two lists I want to iterate on at the same time. Context: photos : Photo.objects.all() and forms = {} for photo in photos: forms[photo.id] = PhotoForm() In other words we've got a list of photo objects and a dict of forms based on the photo.id. Here's an abstraction of the template: {% for photo in photos %} {% include "photoview.html" %} {% comment %} So here I want to use the photo.id as an index to get the correct form. So that each photo has its own form. I would want to have a different action and each form field would be unique. Is that possible? How can I iterate on that? Thanks! {% endcomment %} Quantity: {{ oi.quantity }} {{ form.quantity }} Dimensions: {{ oi.size }} {{ form.size }} {% endfor %} What can I do about this simple case. And how can I make it where every control is automatically updating the server instead of using a form at all? Thanks! James

  • How can I make a family of singletons?

    - by Jay
    I want to create a set of classes that share a lot of common behavior. Of course in OOP when you think that you automatically think "abstract class with subclasses". But among the things I want these classes to do is to each have a static list of instances of the class. The list should function as sort of a singleton within the class. I mean each of the sub-classes has a singleton, not that they share one. "Singleton" to that subclass, not a true singleton. But if it's a static, how can I inherit it? Of course code like this won't work: public abstract A { static List<A> myList; public static List getList() { if (myList==null) myList=new ArrayList<A>(10); return myList; } public static A getSomethingFromList() { List listInstance=getList(); ... do stuff with list ... } public int getSomethingFromA() { ... regular code acting against current instance ... } } public class A1 extends A { ... } public class A2 extends A { ... } A1 somethingfromA1List=(A1) A1.getSomethingFromList(); A2 somethingfromA2List=(A2) A2.getSomethingFromList(); The contents of the list for each subclass would be different, but all the code to work on the lists would be the same. The problem with the above code is that I'd only have one list for all the subclasses, and I want one for each. Yes, I could replicate the code to declare the static list in each of the subclasses, but then I'd also have to replicate all the code that adds to the lists and searches the list, etc, which rather defeats the purpose of subclassing. Any ideas on how to do this without replicating code?

  • Unit Testing a rails 2.3.5 plugin

    - by brad
    I'm writing a new plugin for a rails 2.3.5 app. I've included an app directory (which makes it an engine) so i can easily load some extra routes. Not sure if that affects anything. Anyway, in the test directory i have two files: test_helper.rb and my_plugin_test.rb These files were generated automatically using script/generate plugin my_plugin When I go to vendor/plugins/my_plugin directory and run rake test they don't seem to run. I get the following console output: (in /Users/me/Repos/my_app/source/trunk/vendor/plugins/my_plugin) /Users/me/.rvm/rubies/jruby-1.4.0/bin/jruby -I"lib:lib:test" "/Users/me/.rvm/gems/jruby-1.4.0/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" "test/my_plugin_test.rb" So it obviously sees my test file, but none of the tests inside get run, I just get back to my console prompt. What am I missing here? I figured the generated code would work out of the box Here are the two files test_helper.rb require 'rubygems' require 'active_support' require 'active_support/test_case' my_plugin_test.rb require 'test_helper' class MyPluginTest < ActiveSupport::TestCase # Replace this with your real tests. test "the truth" do assert true end test "Factories are supported" do assert_not_nil Factory end end File structure vendor - plugins - my_plugin - app - config - routes.rb - generators - my_plugin - some generator files.rb - lib - my_plugin.rb - my_plugin - my_plugin_lib_file.rb - rails - init.rb - Rakefile - tasks - my_plugin_tasks.rake - test - test_helper.rb - my_plugin_test.rb

  • Quick MVC2 checkbox question

    - by kevinmajor1
    In order to get my EF4 EntityCollection to bind with check box values, I have to manually create the check boxes in a loop like so: <p> <%: Html.Label("Platforms") %><br /> <% for(var i = 0; i < Model.AllPlatforms.Count; ++i) { %> <%: Model.AllPlatforms[i].Platform.Name %> <input type="checkbox" name="PlatformIDs" value="<%: Model.AllPlatforms[i].Platform.PlatformID %>" /><br /> <% } %> </p> It works, but it doesn't automatically populate the group of check boxes with existing values when I'm editing a model entity. Can I fudge it with something like? <p> <%: Html.Label("Platforms") %><br /> <% for(var i = 0; i < Model.AllPlatforms.Count; ++i) { %> <%: Model.AllPlatforms[i].Platform.Name %> <input type="checkbox" name="PlatformIDs" value="<%: Model.AllPlatforms[i].Platform.PlatformID %>" checked=<%: Model.GameData.Platforms.Any(p => PlatformID == i) ? "true" : "false" %> /><br /> <% } %> </p> I figure there has to be something along those lines which will work, and am just wondering if I'm on the right track. EDIT: I'm purposely staying away from MVC's check box HTML helper methods as they're too inflexible for my needs. My check boxes use integers as their values by design.

  • Anyone know exactly which JMS messages will be redelivered in CLIENT_ACKNOWLEDGE mode if the client

    - by user360612
    The spec says "Acknowledging a consumed message automatically acknowledges the receipt of all messages that have been delivered by its session" - but what I need to know is what it means by 'delivered'. For example, if I call consumer.receive() 6 times, and then call .acknowledge on the 3rd message - is it (a) just the first 3 messages that are ack'd, or (b) all 6? I'm really hoping it's option a, i.e. messages after the one you called acknowledge on WILL be redelivered, otherwise it's hard to see how you could prevent message lost in the event of my receiver process crashing before I've had a chance to persist and acknowledge the messages. But the spec is worded such that it's not clear. I get the impression the authors of the JMS spec considered broker failure, but didn't spend too long thinking about how to protect against client failure :o( Anyway, I've been able to test with SonicMQ and found that it implements (a), i.e. messages 'received' later than the message you call .ack on DO get redelivered in the event of a crash, but I'd love to know how other people read the standard, and if anyone knows how any other providers have implemented CLIENT_ACKNOWLEDGE? (i.e. what the 'de facto' standard is) Thanks Ben

  • Nhibernate: Stop it from joining to a table that is not needed

    - by Aaron
    I have two tables (tbArea, tbPost) that relate to the following classes. class Area { int ID string Name ... } class Post { int ID string Title Area Area ... } These two classes map up with Fluent Nhibernate. Below is the post mapping. public class PostMapping : ClassMap<Post> { public PostMapping() { Cache.NonStrictReadWrite(); this.Table("tbPost"); Id(x => x.ID) .Column("PostID") .GeneratedBy .Identity(); References(x => x.Area) .ForeignKey("AreaID") .Column("AreaID"); ... } } Any time I perform a query on the Post table "where AreaID = 1(any AreaId)", nhibernate will join to the area table. (What Nhibernate generates for a query) SELECT post fields , area fields (automatically added) FROM tbPost p LEFT JOIN tbArea a on p.areaid = a.areaid where p.areaid = 1 I have tried setting Area to LazyLoad, to Fetch.Select, ReadOnly, and any other setting on the reference and still it will always join to Area. I am trying to optimize the backend database queries, and since I don't need the area object loaded just filtered I would like to eliminate the unnecessary join to Area each time I Query post. What configurations do I need to change or mappings to get area to still be related to post in my objects, but not query it when I filter on AreaID?

  • How to Make my application handle Errors for a few different scenarios?

    - by NightsEVil
    so i have this code to extract a program to the temp directory then run it, the problem is it doesn't work perfectly on every computer (for some reason it hits a error or exception sometimes) string tempFolder = System.IO.Path.Combine(System.IO.Path.GetTempPath(), ""); System.Diagnostics.Process defrag1 = System.Diagnostics.Process.Start(@"Programs\Optimize\AusLogics_Defrag.exe", string.Format(" -o{0} -y", tempFolder)); defrag1.WaitForExit(); string executableDirectoryName = Path.GetDirectoryName(Application.ExecutablePath); System.Diagnostics.Process defrag2 = System.Diagnostics.Process.Start(tempFolder + "\\" + "AusLogics_Defrag" + "\\" + "DiskDefrag.exe", ""); defrag2.WaitForExit(); System.IO.Directory.Delete(tempFolder + "\\" + "AusLogics_Defrag", true); and what i wanna know is there a way that say if it starts to extract but hits a error (no matter what it is) it will automatically change and go to this code, but if it DOESN'T hit a error it continues as it was meant to? string tempFolder = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData); System.Diagnostics.Process defrag1 = System.Diagnostics.Process.Start(@"Programs\Optimize\AusLogics_Defrag.exe", string.Format(" -o{0} -y", tempFolder)); defrag1.WaitForExit(); string executableDirectoryName = Path.GetDirectoryName(Application.ExecutablePath); System.Diagnostics.Process defrag2 = System.Diagnostics.Process.Start(tempFolder + "\\" + "AusLogics_Defrag" + "\\" + "DiskDefrag.exe", ""); defrag2.WaitForExit(); System.IO.Directory.Delete(tempFolder + "\\" + "AusLogics_Defrag", true); with the path going to the application data folder? and if THAT hits a error it would change that path to this, but if it DOESN'T hit a error it continues as it was meant to? string tempFolder = System.Environment.GetEnvironmentVariable("HomeDrive");

  • jquery image fading with tabs

    - by StealthRT
    Hey all, i am trying my best to figure out how to go about doing this: I have 2 tabs. When the page loads tab1 is selected automatically. This shows the tab as 1.0 transparency while tab2 stays at 0.7. Once the user clicks on tab2, tab1 goes to 0.7 transparency and tab2 goes to 1.0. However, i can not seem to get it to do that! Here is my code: <script type="text/javascript"> function checkTab(theTab) { $('#tab1').fadeTo(250, 0.70); $('#tab2').fadeTo(250, 0.70); if ($("#tabActive").val() == theTab) { $(theTab).fadeTo(250, 1); } } $(document).ready(function() { $('#tab1').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab1')}); $('#tab2').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab2')}); $('#tab2').fadeTo(250, 0.70); $('#tabActive').val('tab1'); }); </script> <li class="stats"><img src="images/Stats.png" name="nav1" width="70" height="52" id="tab1" onclick="$('#tabActive').val('tab1');" /></li> <li class="cal"><img src="images/cal.png" name="nav1" width="70" height="52" id="tab2" onclick="$('#tabActive').val('tab2');" /></li> <input name="tabActive" id="tabActive" type="text" /> Any help would be great! :) David

  • How to update maven local repository with newer artifacts from a remote repository?

    - by Richard
    My maven module A has a dependency on another maven module B provided by other people. When I run "mvn install" under A for the first time, maven downloads B-1.0.jar from a remote repository to my local maven repository. My module A builds fine. In the mean time, other people are deploying newer B-1.0.jar to the remote repository. When I run "mvn install" under A again, maven does not download the newer B-1.0.jar from the remote repository to my local repository. As a result, my module A build fails due to API changes in B-1.0.jar. I could manually delete B-1.0.jar from my local repository. Then maven would download the latest B-1.0.jar from the remote repository the next time when I run "mvn install". My question is how I can automatically let maven download the latest artifacts from a remote repository. I tried to set updatePolicy to "always". But that did not do the trick.

  • How can I split my conkeror-rc config over multiple files?

    - by Ryan Thompson
    Short version: can you help me fill in this code? var conkeror_settings_dir = ".conkeror.mozdev.org/settings"; function load_all_js_files_in_dir (dir) { var full_path = get_home_directory().appendRelativePath(dir); // YOUR CODE HERE } load_all_js_files_in_dir(conkeror_settings_dir); Background I'm trying out Conkeror for web browsing. It's an emacs-like browser running on Mozilla's rendering engine, using javascript as configuration language (filling the role that elisp plays for emacs). In my emacs config, I have split my customizations into a series of files, where each file is a single unit of related options (for example, all my perl-related settings might be in perl-settings.el. All these settings files are loaded automatically by a function in my .emacs that simply loads every elisp file under my "settings" directory. I am looking to structure my Conkeror config in the same way, with my main conkeror-rc file basically being a stub that loads all the js files under a certain directory relative to my home directory. Unfortunately, I am much less literate in javascript than I am in elisp, so I don't even know how to "source" a file.
