  • Hover text at mouse created from firefox toolbar add-on

    - by c-square
    Hi all, I'm creating a firefox add-on, and I have a situation where if someone clicks on a specific item in my toolbarbutton menupopup, I want to display some text to appear beside the mouse for a couple seconds. I don't mean mouseover text, because when they click on the item, the I close the menupopup. I mean something like what's shown at this site: http://www.kingsquare.nl/cursormessage The normal way of doing this would be with javascript and a div that would have the text I want to show. Unfortunately, I've discovered that the toolbarbutton can't have an effect on the main window, which is where I'd need to place the div to show. I've tried getting JQuery to work and haven't been successful either. Any help would be greatly appreciated. Thanks!

  • Get the value for a WPF binding

    - by Jose
    Ok, I didn't want a bunch of ICommands in my MVVM ViewModels so I decided to create a MarkupExtension for WPF that you feed it a string(the name of the method), and it gives you back an ICommand that executes the method. here's a snippet: public class MethodCall : MarkupExtension { public MethodCall(string methodName) { MethodName = methodName; CanExecute = "Can" + methodName; } public override object ProvideValue(IServiceProvider serviceProvider) { Binding bin= new Binding { Converter = new MethodConverter(MethodName,CanExecute) }; return bin.ProvideValue(serviceProvider); } } public class MethodConverter : IValueConverter { string MethodName; public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { //Convert to ICommand ICommand cmd = ConvertToICommand(); if (cmd == null) Debug.WriteLine(string.Format("Could not bind to method 'MyMethod' on object",MethodName)); return cmd; } } It works great, except when the binding fails(e.g. you mistype). When you do this in xaml: {Binding MyPropertyName} you see in the output window whenever the binding fails. and it tells you the propertyName the Type name etc. The MethodConverter Class can tell you the name of the method that failed, but it can't tell you the source object type. Because the value will be null. I can't figure out how to store the source object type so for the following class public class MyClass { public void MyMethod() { } } and the following xaml: <Button Command={d:MethodCall MyMethod}>My Method</Button> It currently says: "Could not bind to method 'MyMethod' on object but I would like it to say: "Could not bind to method 'MyMethod' on object MyClass Any ideas?

  • Compiling Gearman extension for PHP on OS-X Snow Leopard with Zend Server Community Edition

    - by GrumpyCanuck
    I was wondering if anyone else has figured out how to solve this problem. Whether I install the extension via PECL or compile it by hand, I get the same error: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/zend/lib/php_extensions/gearman.so' - dlopen(/usr/local/zend/lib/php_extensions/gearman.so, 9): no suitable image found. Did find: /usr/local/zend/lib/php_extensions/gearman.so: mach-o, but wrong architecture in Unknown on line 0 I have no idea how to fix this problem and I can only bang my head into my desk so many times.

  • The uncatchable exception

    - by chaiguy
    Another custom MarkupExtension binding question... This time, my converter is being called before DataContext is set on the target element. This isn't a big deal because it will get updated when DataContext eventually receives a value. What is causing problems is the NullReferenceException I'm getting because of DataContext being null. Even though I'm attempting to catch the exception in my value converter: try { return ( (MethodInfo)_member ).Invoke( parameter, null ); } catch { return Binding.DoNothing; } For some reason the debugger is still halting at this point. Now I'm thinking it could be because the exception is happening in another assembly from where it is being caught (I'm trying to package this in a reusable class library, and _member above points to a method in the application assembly). If I run my little test app without the debugger it works fine, however my application is a little more robust and has general exception handling which is getting triggered because of this. I'm wondering if there is just some attribute or something (or perhaps some reflection parameter I'm missing?) I can use to make the exception be caught like it's supposed to.

  • 'System.Windows.Data.MultiBinding' is not a valid value for property 'Text'.

    - by chaiguy
    I'm trying to write a custom MarkupExtension that allows me to use my own mechanisms for defining a binding, however when I attempt to return a MultiBinding from my MarkupExtension I get the above exception. I have: <TextBlock Text="{my:CustomMarkup ...}" /> CustomMarkup returns a MultiBinding, but apparently Text doesn't like being set to a MultiBinding. How come it works when I say: <TextBlock> <TextBlock.Text> <MultiBinding ... /> </TextBlock.Text> </TextBlock> But it doesn't work the way I'm doing it?

  • Class Plugins in PHP?

    - by YuriKolovsky
    i just got some more questions while learning PHP, does php implement any built in plugin system? so the plugin would be able to change the behavior of the core component. for example something like this works: include 'core.class.php'; include 'plugin1.class.php'; include 'plugin2.class.php'; new plugin2; where core.class.php contains class core { public function coremethod1(){ echo 'coremethod1'; } public function coremethod2(){ echo 'coremethod2'; } } plugin1.class.php contains class plugin1 extends core { public function coremethod1(){ echo 'plugin1method1'; } } plugin2.class.php contains class plugin2 extends plugin1 { public function coremethod2(){ echo 'plugin2method2'; } } This would be ideal, if not for the problem that now the plugins are dependable on each other, and removing one of the plugins: include 'core.class.php'; //include 'plugin1.class.php'; include 'plugin2.class.php'; new plugin2; breaks the whole thing... are there any proper methods to doing this? if there are not, them i might consider moving to a different langauge that supports this... thanks for any help.

  • Link to another file in chrome extension

    - by Hintswen
    I want to have a link in the popup.html file for my extension that loads another file (which will be included with the extension) how can I do this? or will I need to keep it in the same page? I tried using this code: <a href="/mail.html"> <img id="newmail_icon" src="" width="16" height="16" /> <span id="newmail">loading</span><br /> </a> But when I click the link nothing happens. I just found out that adding target="_blank" to the link will make it work and open in a new tab, but I can't get it to open in the popup. I have tried target="_self" but it didn't do anything.

  • How to Force an Exception from a Task to be Observed in a Continuation Task?

    - by Richard
    I have a task to perform an HttpWebRequest using Task<WebResponse>.Factory.FromAsync(req.BeginGetRespone, req.EndGetResponse) which can obviously fail with a WebException. To the caller I want to return a Task<HttpResult> where HttpResult is a helper type to encapsulate the response (or not). In this case a 4xx or 5xx response is not an exception. Therefore I've attached two continuations to the request task. One with TaskContinuationOptions OnlyOnRanToCompletion and the other with OnlyOnOnFaulted. And then wrapped the whole thing in a Task<HttpResult> to pick up the one result whichever continuation completes. Each of the three child tasks (request plus two continuations) is created with the AttachedToParent option. But when the caller waits on the returned outer task, an AggregateException is thrown is the request failed. I want to, in the on faulted continuation, observe the WebException so the client code can just look at the result. Adding a Wait in the on fault continuation throws, but a try-catch around this doesn't help. Nor does looking at the Exception property (as section "Observing Exceptions By Using the Task.Exception Property" hints here). I could install a UnobservedTaskException event handler to filter, but as the event offers no direct link to the faulted task this will likely interact outside this part of the application and is a case of a sledgehammer to crack a nut. Given an instance of a faulted Task<T> is there any means of flagging it as "fault handled"? Simplified code: public static Task<HttpResult> Start(Uri url) { var webReq = BuildHttpWebRequest(url); var result = new HttpResult(); var taskOuter = Task<HttpResult>.Factory.StartNew(() => { var tRequest = Task<WebResponse>.Factory.FromAsync( webReq.BeginGetResponse, webReq.EndGetResponse, null, TaskCreationOptions.AttachedToParent); var tError = tRequest.ContinueWith<HttpResult>( t => HandleWebRequestError(t, result), TaskContinuationOptions.AttachedToParent |TaskContinuationOptions.OnlyOnFaulted); var tSuccess = tRequest.ContinueWith<HttpResult>( t => HandleWebRequestSuccess(t, result), TaskContinuationOptions.AttachedToParent |TaskContinuationOptions.OnlyOnRanToCompletion); return result; }); return taskOuter; } with: private static HttpDownloaderResult HandleWebRequestError( Task<WebResponse> respTask, HttpResult result) { Debug.Assert(respTask.Status == TaskStatus.Faulted); Debug.Assert(respTask.Exception.InnerException is WebException); // Try and observe the fault: Doesn't help. try { respTask.Wait(); } catch (AggregateException e) { Log("HandleWebRequestError: waiting on antecedent task threw inner: " + e.InnerException.Message); } // ... populate result with details of the failure for the client ... return result; } (HandleWebRequestSuccess will eventually spin off further tasks to get the content of the response...) The client should be able to wait on the task and then look at its result, without it throwing due to a fault that is expected and already handled.

  • Extending LINQ classes to my own partial classes in different namespaces?

    - by sah302
    I have a .dbml file which of course contains the auto-generated classes based on my tables. I would however, like to extend them to my own classes. Typically I design such that each of my tables get their own namespace in their own folder containing all of their associated dao and service classes. So if I am dealing with a page that only has to do with 'customers' for instance, I can only include the customerNS. But when using LINQ I seem to be unable to do this. I have tried removing a default namespace from the project, I have tried putting the .dbml file into it's own folder with a custom namespace and then adding a 'using' statement, but no nothing works. I also saw the Entity Namespace, Context Namespace, and Custom Tool Namespace properties associated with the .dbml file and tried setting all these to names x and trying 'using x' in my other class to allow me to extend partial classes, but it just doesn't work. Is this possible or do I have to keep all extended partial classes in the same namespace as the .dbml file?

  • How do you use Exslt.dyn (especially the 'evaluate' method) in Umbraco?

    - by jeffreypriebe
    I am trying to execute the string contained in an XSL variable. Umbraco has hooks for several Exslt pieces, but it seems the Exslt.dyn (Exslt.dynamic) is not one of them. How do you add it in? Acceptable methods (in order of preference: Writing your own XSLT extension (possibly using existing Umbraco code for Exslt Dynamic). Uploading the XSL from http://www.exslt.org/dyn/functions/evaluate/index.html into Umbraco. Modifying the Umbraco source to add it (possibly using existing Umbraco code for Exslt Dynamic). The reason I mention Exslt Dyanmic is because some Umbraco XSLT sources show a reference that I am assuming existing in some versions of Umbraco. I cannot find it in the source code, however. (Example: the XSL sources pasted in here: http://our.umbraco.org/projects/starter-kits/business-website-starter-pack/general-%28bugs,-feedback,-feature-requests%29/8085-Changing-the-first-day-to-fx-monday)

  • How do I create a custom network connection entry?

    - by David Brown
    I have a Sprint MiFi 3G router that exposes its current signal strength over HTTP. I've developed a very simple tray application that displays this. However, what I would really like to do is create a custom network connection entry so the router's 3G signal strength (along with the current network version) displays when clicking on the network connections tray icon (in Windows 7, at least). Is it possible to do this with a shell extension or something (preferably in C#)? If so, how?
