  • Proper error handling in a custom Zend_Autoloader?

    - by Pekka
    I'm building a custom autoloader based on Zend Framework's autoloading (related question here). The basic approach, taken from that question, is class My_Autoloader implements Zend_Loader_Autoloader_Interface { public function autoload($class) { // add your logic to find the required classes in here } } and then binding the new autoloader class to a class prefix. Now what I'm unsure about is how to handle errors inside the autoload method (for example, "class file not found") in a proper, ZF compliant way. I'm new to the framework, its conventions and style. Do I quietly return false and let the class creation process crash? Do I output an error or log message somehow (which would be nice to pinpoint the problem) and return false? If so, what is the Zend way of doing that? Do I trigger an error? Do I throw an exception? If so, what kind?

  • Creating an Attribute to check for Exceptions

    - by BiffBaffBoff
    I'm creating an attribute so that whenever an exception occurs on my site, I'll receive an email detailing the exception. I've got so far but my Attribute code doesn't seem to fire if an exception occurs: public class ReportingAttribute : FilterAttribute, IExceptionFilter { public void OnException(ExceptionContext filterContext) { // This will generate an email to me ErrorReporting.GenerateEmail(filterContext.Exception); } } Then above my Controller I'm doing: [ReportingAttribute] public class AccountController : Controller The other way to do it is ofcourse putting ErrorReporting.GenerateEmail(ex) inside my catch blocks? There must be a simpler way? Thats why I thought of creating the Attribute to handle this

  • VST plugin : using FFT on audio input buffer with arbitrary size, how ?

    - by Led
    I'm getting interested in programming a VST plugin, and I have a basic knowledge of audio dsp's and FFT's. I'd like to use VST.Net, and I'm wondering how to implement an FFT-based effect. The process-code looks like public override void Process(VstAudioBuffer[] inChannels, VstAudioBuffer[] outChannels) If I'm correct, normally the FFT would be applied on the input, some processing would be done on the FFT'd data, and then an inverse-FFT would create the processed soundbuffer. But since the FFT works on a specified buffersize that will most probably be different then the (arbitrary) amount of input/output-samples, how would you handle this ?

  • Using a named system semaphore as an event to trigger something in another process.

    - by jbraz
    I have a thread that runs all the time: private void DoSomeStuffThread() { Semaphore sem = new Semaphore(0, 3, "sem_DoStuff"); sem.WaitOne(); do { //do some stuff } while (sem.WaitOne()); } I want to be able to only execute the stuff in the do block when something from another process says so. I am trying to use the "sem_DoStuff" named system semaphore to allow this to happen. The code that gets executed in my other process: public string DoStuff() { try { Semaphore sem = Semaphore.OpenExisting("sem_DoStuff"); sem.Release(); } catch (Exception e) { return e.Message; } } So, the idea is that when DoStuff gets called, the semaphore gets released, and DoSomeStuffThread stops waiting, executes what is in the do block, and then waits for DoStuff again before it is getting called. But, when DoStuff gets called, I'm getting the exception 'No handle of the given name exists.'. What am I doing wrong? Thanks.

  • Codeigniter deny access to directory of controllers with apache config

    - by MAZUMA
    I’d like to restrict access to a folder of controllers that are used for admin purposes only. I’ve tried a number of ways and not coming up with a solution. These controllers are behind password protection. But, I’d like to just remove it from view if someone happens to stumble upon the right directory. Can this be done? I’d rather not do it from htaccess. I have access to the apache config files, so I’d like to handle it there. Does it have anything to do with the way Codeigniter routes? Or, am I just way off? This what I’m using that doesn’t work <Directory /var/www/application/controllers/folder/> Order deny,allow Deny from all Allow from xxx.xxx.xxx.xxx </Directory>

  • Stopping function on event in vb.net

    - by afilatun
    I have a vb.net application which does some processing. This processing can take a while. The application doesn't respond until the processing has ended and then it handle all events (such as click on buttons) that the user has done during the processing. I'd like to add a "Stop" button so that the user can stop the processing at some point. How can I do that? Could threading the processing (which is done in a function of the application) be a possible solution? I tried to add a button which change a boolean value and putting the code of the processing function inside a while statement based on that boolean value. However it doesn't work because the click event on the button is processed only after the end of the processing.

  • VB6 Parser/Lexer/Scripter

    - by rlb.usa
    I've got a game in VB6 and it works great and all, but I have been toying with the idea of creating a scripting engine. Ii'm thinking I'd like VB6 to read in flat text script files for me and then lex/parse/execute them. I have good programming experience, and I've built a simple C compiler, as well as a LOGO emulator before. My question is: Are there any tools that I can use, like Lexx/Yakk/Bison to help me? How should I approach this problem in regards to lexing, parsing, and feeding the commands back to VB6 so I can handle them? Is this idea a BAD IDEA in the sense that there are too many obstacles in the way (For example, building minesweeper in assembly, though not impossible, is very difficult, and a bad idea.)?

  • Fluent NHibernate + multiple databases

    - by Pablote
    My project needs to handle three databases, that means three session factories. The thing is if i do something like this with fluent nhibernate: .Mappings(m = m.FluentMappings.AddFromAssembly(Assembly.GetExecutingAssembly())) the factories would pick up all the mappings, even the ones that correspond to another database I've seen that when using automapping you can do something like this, and filter by namespace: .Mappings(m = m.AutoMappings.Add(AutoMap.AssemblyOf().Where(t = t.Namespace == "Storefront.Entities"))) I havent found anything like this for fluent mappings, is it possible?? The only solutions I can think of are: either create separate assemblies for each db mapping classes or explicitly adding each of the entities to the factory configuration. I would prefer to avoid both, if possible. Thanks.

  • Invalidating non-client areas

    - by Ismael
    I've a window which I draw a custom border/caption, in order to do that I handle WM_NCPAINT message. My captin has two backgrounds a brighter one when it is the active window, and a darker one when it is in the background. But under some circumstances, for example when the window loses/gain focus, my caption is not updated so I end with the wrong background. Until now I've handled WM_NCACTIVATE, and send a RedrawWindow(hwnd, NULL, NULL, RDW_FRAME|RDW_INVALIDATE), but this causes the whole window to repaint. Do you have any advice about this?

  • Is there a way to combine streaming data retrieval with hibernate?

    - by Steve B.
    For the purposes of handling very large collections (and by very large I just mean "likely to throw OutOfMemory exception"), it seems problematic to use Hibernate because normally collection retrieval is done in a block, i.e. List values=session.createQuery("from X").list(), where you monolithically grab all N-million values and then process them. What I'd prefer to do is to retrieve the values as an iterator so that I grab 1000 or so (or whatever's a reasonable page size) at a time. Apart from writing my own iteration (which seems like it's likely to be re-inventing the wheel) is there a hibernate-native way to handle this?

  • User control attributes at design-time

    - by ciscoheat
    I'm testing a simple User Control in Visual Studio 2008: A Panel named Wrapper with some controls inside. Can Visual Studio handle this at design time? public partial class TestControl : System.Web.UI.UserControl { [Description("Css class of the div around the control.")] [CssClassProperty] public string CssClass { get { return Wrapper.CssClass; } set { Wrapper.CssClass = value; } } } When setting the CssClass property, it doesn't update the css of the Panel at design time. Am I hoping for too much?

  • Rack URL Mapping

    - by Puru puru rin..
    Hi, I am trying to write two kind of Rack routes. Rack allow us to write such routes like so: app = Rack::URLMap.new('/test' => SimpleAdapter.new, '/files' => Rack::File.new('.')) In my case, I would like to handle those routes: "/" or "index" "/*" in order to match any other routes So I had trying this: app = Rack::URLMap.new('/index' => SimpleAdapter.new, '/' => Rack::File.new('./public')) This works well, but... I don't know how to add '/' path (as alternative of '/index' path). The path '/*' is not interpreted as a wildcard, according to my tests. Do you know how I could do? Thanks

  • How to use pointer from COM object on C#?

    - by Jaeh
    All. I'm trying to use my old dll file on .net project. So I converted this unmanaged COM object to managed one by using [tlbimp.exe] util from Windows SDK. However, one method returns a Object as a return value, but whenever I try to use it, my program generates an error. The weird thing is below: //Object[] item = s.GetObjects(); //this generates an type error Object item = s.GetObjects(); //this works okay System.WriteLine(items); //prints System.Object[] rather than System.Object. It seems like it returns a pointer which contains an object array. Isn't it ? Please anyone tell me how to handle this, and is there any documentation for this issue ?

  • jQuery: Sorting hierarchical data?

    - by Industrial
    Hi everybody, I have tried for some time to work out a way of sorting nested categories with jQuery. I failed to build my own plugin to do this, so I tried to find something that were available already. Tried a few hours now with this one, http://www.jordivila.net/code/js/jquery/ui-widgetTreeList_inheritance/widgetTreeListSample.aspx and cant get it to work. What are the alternatives of creating a jQuery / jQuery UI script that handles sorting children and parent categories in a way that can be combined with a AJAX PHP backend to handle the actual sorting in the database? Thanks!

  • Sending out 20,000+ emails with asp.net

    - by Kyle
    I am writing an application that will need to send a massive amount of emails to our students who will be selected from our database (each email will be personalized to the extent that will include their name, course of study etc...so needs to be sent one at a time). I could do this looping over an SmtpClient, but I'm afraid that with the numbers I'm trying to send, I'll ultimately run into timeout issues or my thread being killed because of lack of machine resources. At this point I'm just looking for suggestions of a better way to handle this, or if looping over SmtpClient is an ok solution, how I should go about handling it to prevent what I posted above. Would a web service be a better alternative? Please advise, TIA

  • Is there a best coding style for indentations (same line, next line)?

    - by Luis Soeiro
    I prefer Pascal-like coding style, where the beginning and ending of a code block are on the same column. I think that it is easier to read and to handle cut and paste than the other kind of coding style. The style I prefer (Pascal-like): void fooBar(String s) { int a; int length=s.length(); for (int i=0;i<length;i++) { if (i>10) { System.out.println(i); System.out.println(s.charAt(i)); } } } The style that was adopted by the Java community: void fooBar(String s) { int a; int length=s.length(); for (int i=0;i<length;i++){ if (i>10){ System.out.println(i); System.out.println(s.charAt(i)); } } } So why do you use one type or the other (please cite an objective reason)?

  • How to make schema and code dynamic?

    - by Jonarch
    I want to make my database schema and application code as dynamic as possible to handle "unknown" use cases and changes. Developing in PHP and MySQL. Twice now I have had to change my entire schema including table and column names and this means the developers have to go back to the application code and modify all the SQL queries and table/columns names. So to prevent this I want to if just like we do on pages where we have page content, title bar etc dynamic like a %variable%, can we do it for the schema and maybe even for the php code functions and classes somehow? It takes weeks to re-do all changes like this vs if it is dynamic it can be done in under a day.

  • any way to use ajax with jstl customtags without duplicating tags in javascript?

    - by CodeMonkeyB
    I am working on a page where part of the content is loaded normally and the pages are rendered using jsps. The product images and links generated on that page are by custom jstl tags. When the user scrolls more products are requested from the server in a JSON response and then using UnderscoreJS templates they are rendered and added to the bottom of the page. Is there any way I can use the JSTL tags in Javascript without recreating them using a javascript function (it won't be possible to re-create all of them in javascript). What is the best way to handle this scenario? I guess I could return a rendered html response for the ajax call, but that would mean I have some ajax requests which use json and some that use rendered html...

  • Don't Change URL in Browser When Clicking <asp:LinkButton>

    - by Corey Goldberg
    I have an ASP.NET page that uses a menu based on asp:LinkButton control in a Master page. When a user selects a menu item, an onclick handler calls a method in my C# code. The method it calls just does a Server.Transfer() to a new page. From what I have read, this is not supposed to change the URL displayed in the browser. The problem is it that the URL changes in the browser as the user navigates the menu to different pages. Here is an item in the menu: <asp:LinkButton id="foo" runat="server" onclick="changeToHelp"><span>Help</span> </asp:LinkButton> In my C# code, I handle the event with a method like: protected void changeToHelp(object sender, EventArgs e) { Server.Transfer("Help.aspx"); } Any ideas how I can navigate through the menu without the browser's URL bar changing?

  • Does NavigationHandler.handleNavigation() clear the flash?

    - by kgrad
    I am using JSF2.0 Mojarra 2.0.2. I have a method that logs out a user and puts a logout message in the flash, forwards to the login page (which has a div that prints out the flash). However, when I use navigationHandlers handleNavigation method for some reason the flash is not being displayed. I have a similar method that forwards a user to the login page if he/she isn't logged in. If I handle the navigation through an h:link and just call the logout method directly, the flash is displayed as normal, but if I use the handleNavigation() method, the flash is cleared for some reason. The code in question is: public void performLogout() { getFacesContext().getExternalContext().invalidateSession(); setCurrentUser(null); getFlash().put("notice", "Successfully logged out."); super.getFacesContext().getApplication().getNavigationHandler() .handleNavigation(getFacesContext(), null, "login"); } Is there some way I can keep the flash when navigating like this? thanks.

  • decode mysql query before returning it to view

    - by stormdrain
    I'm running a query to mysql that returns encrypted data. I'd like, if possible, to decode the results before sending it to the view. It seems like better form to handle the decoding in the controller (or even the model) rather than inside the view. I can't seem to wrap my head around how to do it, though. I was thinking I could iterate through the object, decodode it, and push it to another array that would be sent to the view. Problem with this is I won't know (and need to keep) the indexes of the query. So the query might return something like: [id] => 742 [client_id] => 000105 [last] => dNXcw6mQPaGQ4rXfgIGJMq1pZ1dYAim0 [first] => dDF7VoO37qdtYoYKfp1ena5mjBXXU0K3dDlcq1ssSvCgpOx75y0A== [middle] =>iXy6OWa48kCamViDZFv++K6okIkalC0am3OMPcBwK8sA== [phone] => eRY3zBhAw2H8tKE Any ideas?

  • Are protected constructors considered good practice?

    - by Álvaro G. Vicario
    I'm writing some little helper classes to handle trees. Basically, I have a node and a special root node that represents the tree. I want to keep it generic and simple. This is part of the code: <?php class Tree extends TreeNode{ public function addById($node_id, $parent_id, $generic_content){ if( $parent = $this->findNodeById($parent_id) ){ $parent->addChildById($node_id, $generic_content); } } } class TreeNode{ public function __construct($node_id, $parent_id, $generic_content){ // ... } protected function addChildById($node_id, $generic_content){ $this->children[] = new TreeNode($this->node_id, $node_id, $generic_content); } } $Categories = new Tree; $Categories->addById(1, NULL, $foo); $Categories->addById(2, NULL, $bar); $Categories->addById(3, 1, $gee); ?> My questions: Is it sensible to force TreeNode instances to be created through TreeNode::addById()? If it's so, would it be good practise to declare TreeNode::__construct() as private/protected?

  • Obtain patterns in one file from another using ack or awk or better way than grep?

    - by Rock
    Is there a way to obtain patterns in one file (a list of patterns) from another file using ack as the -f option in grep? I see there is an -f option in ack but it's different with the -f in grep. Perhaps an example will give you a better idea. Suppose I have file1: file1: a c e And file2: file2: a 1 b 2 c 3 d 4 e 5 And I want to obtain all the patterns in file1 from file2 to give: a 1 c 3 e 5 Can ack do this? Otherwise, is there a better way to handle the job (such like awk or using hash) because I have millions of records in both files and really need an efficient way to complete? Thanks!
