  • flex: cant edit item in Datagrid with override set data method

    - by Markus
    Hi everybody, I've a custom itemRenderer for my datagrid. To set the actual data I use the following method: override public function set data(side:Object):void{ ... } As soon as I use this function the cell doesn't show up any item Editor anymore. Why is that? When I remove this function the itemEditor is working but with the wrong initialization data... What's the proper way to handle this? Thanks, Markus

  • Scripting Languages vs. Compiled Languages for web development

    - by Austin Hyde
    Though I come from a purely PHP background on the web development side of programming, I have also spent much time with C# and C++ on the desktop. I don't really want to spark any flame wars, but: When should you use scripting languages over compiled languages for website development? (and vice versa) Just to clarify, for the sake of this question, I define a "scripting language" to mean an interpreted language like PHP, Python, or Ruby, and a "compiled language" to mean a strongly typed, compiled language like C#, C++, Java, or VB.

  • Reading URL Anchor on IE

    - by tominated
    Hi, I've got a page full of links to another page with anchors on the end (like this: index.html#anchor). On the page they point to, I have a script that is supposed to read where the anchor points to in order to display something. On firefox it works perfectly, But I've noticed that IE seems to remove the #anchor from the end of the url, so the script can't grab the text. Is there a way around this, without any server side code?

  • Quick top level server language question.

    - by Shane
    Right, so if you have to decide on a server-side language for a distributed Linux-based server backend, would you choose: PHP Mono ASP.net Java As a C++ programmer, I'm thinking Java+Tomcat, but I'd love to hear experienced thoughts here, especially relating to debugging and IDE (likely Eclipse). Also, please, it's not a flame question. I'm seeing excellent sites written in all, I'm just thinking about the compile/debug/release cycle. Cheers, Shane

  • Web Hosting Plan

    - by Laith J
    I'm looking for a new web hosting service, currently I'm using GoDaddy's Economy plan but it offers only PHP server-side scripting. For my next project it looks like I'm gonna need to use Java. Currently I pay ~60 USD per year for both the domain and the web hosting plan. Anyone knows of a web hosting service that supports Java and isn't much more expensive than this? Thanks, God bless

  • Find window previously opened by window.open

    - by spender
    We've got the following situation, running from a single domain: Page A uses window.open() to open a named window (a popup player). window.open() gives page A a reference to the window. User now reloads page A. The reference to the named window is lost. Using window.open() to "find" the window has the unfortunate side effect of reloading it (undesirable). Is there any other way to get a reference to this window?

  • /usr/local or /opt ?

    - by SirFabel
    Hi Guys, How do you generally proceed for your package installations on Linux, for packages that are not part of your distrib's repos? On my side I am used to install in /opt. But since, I saw this doc on the Internet: http://www.pathname.com/fhs/. Now I am confused: apparently /usr/local would be also a possibility. What is the difference between both? Any best practices to share? Thanks SirFabel

  • ASP.NET Web Service - how to handle special characters in strings?

    - by Vlorg
    To show this fundamental issue in .NET and the reason for this question, I have written a simple test web service with one method (EditString), and a consumer console app that calls it. They are both standard web service/console applications created via File/New Project, etc., so I won't list the whole code - just the methods in question: Web method: [WebMethod] public string EditString(string s, bool useSpecial) { return s + (useSpecial ? ((char)19).ToString() : ""); } [You can see it simply returns the string s if useSpecial is false. If useSpecial is true, it returns s + char 19.] Console app: TestService.Service1 service = new SCTestConsumer.TestService.Service1(); string response1 = service.EditString("hello", false); Console.WriteLine(response1); string response2 = service.EditString("hello", true); // fails! Console.WriteLine(response2); [The second response fails, because the method returns hello + a special character (ascii code 19 for argument's sake).] The error is: There is an error in XML document (1, 287) Inner exception: "'', hexadecimal value 0x13, is an invalid character. Line 1, position 287." A few points worth mentioning: The web method itself WORKS FINE when browsing directly to the ASMX file (e.g. http://localhost:2065/service1.asmx), and running the method through this (with the same parameters as in the console application) - i.e. displays XML with the string hello + char 19. Checking the serialized XML in other ways shows the special character is being encoded properly (the SERVER SIDE seems to be ok which is GOOD) So it seems the CLIENT SIDE has the issue - i.e. the .NET generated proxy class code doesn't handle special characters This is part of a bigger project where objects are passed in and out of the web methods - that contain string attributes - these are what need to work properly. i.e. we're de/serializing classes. Any suggestions for a workaround and how to implement it? Or have I completely missed something really obvious!!? Thanks in advance... PS. I've not had much luck with getting it to use CDATA tags (does .NET support these out of the box?).

  • DRY URL's in Django Javascript

    - by Noio
    I'm using Django on Appengine. I'm using the django reverse() function everywhere, keeping everything as DRY as possible. However, I'm having trouble applying this to my client-side javascript. There is a JS class that loads some data depending on a passed-in ID. Is there a standard way to not-hardcode the URL that this data should come from? var rq = new Request.HTML({ 'update':this.element, }).get('/template/'+template_id+'/preview'); //The part that bothers me.

  • How to output formatted HTML from PHP?

    - by Tim
    I like to format all my HTML with tabs for neatness and readability. Recently I started using PHP and now I have a lot of HTML output that comes from in between PHP tags. Those output lines all line up one the left side of the screen. I have to use /n to make a line go to the next. Is there anything like that for forcing tabs, or any way to have neat HTML output coming from PHP?

  • What is holding up HD video conferencing on the web?

    - by Tristan
    What exactly is holding up real-time HD video conferencing on the web? Live, low-latency, video has lots of great applications beyond video chat: for instance, virtual desktops / vnc, remote control of applications, and server-side visualization. So what exactly are the technical barriers that remain? Existing video and remote desktop applications show latency problems are overrated for many applications. Bandwidth for many users now can easily stream 720p and even 1080p. Top-end video conferencing demos already do 1080p

  • Visual Source Safe on Mac OS X

    - by Jonathan Badeen
    Is there an application or API for using/accessing Visual SourceSafe (6.0) under Mac OS X? I'm currently using VSS Connect under Parallels for working with our company's ASP.NET site/s. I currently have my Windows drive shared and try to use TextMate on the Mac side to actually edit files. It would be nice to have the ability to check files in/out outside of my virtual machine though.

  • WCF doesn't find client configuration

    - by ultraman69
    Hi ! I have a WCF service on server B. Then on the machine A is the client, which is a Windows service. In a separate dll stands all the business logic for this service. So my proxy for the WCF is on that side. I have 2 app.config (client side only) : 1 for the service and another one in the dll. So I tried (for test purpose) puting the servicemodel config section in both. Both still, it doesn't work, it says that it can't find the endpoint with that name and for that contract... What I'm trying to do here is modify the configuration programatically. Here' the code in the business layer dll : Dim ep As New EndpointAddress(New Uri(ConfigurationManager.AppSettings(nomServeurCible)), _ EndpointIdentity.CreateDnsIdentity(ConfigurationManager.AppSettings("Identity_" & nomServeurCible))) serviceCible = New ServiceProxy.ExecOperClient("wsHttp", ep) And here is a sample of the config file : <add key="TEST1" value="http://TEST1:8000/MySpacePerso/ExecOperService"/> <add key="TEST1_CertificateSerialNumber" value="10 hj 6y 7b 00 01 32 12 01 21"/> <add key="Identity_TEST1" value="TEST1"/> <system.serviceModel> <client> <endpoint address="http://SERV_NAME:8000/CSSTQDA/ExecOperService" binding="wsHttpBinding" behaviorConfiguration="myClientBehavior" bindingConfiguration="MybindingCon" contract="ExecOper.Service.IExecOper" name="wsHttp"> <identity> <dns value="SERV_CERT_NAME"/> </identity> </endpoint> </client> <bindings> <wsHttpBinding> <binding name="MybindingCon"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceTraitementBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="myClientBehavior"> <clientCredentials> <serviceCertificate> <authentication certificateValidationMode="ChainTrust" revocationMode="NoCheck"/> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors>

  • Having trouble getting MEF imports to be resolved

    - by Dave
    This is sort of a continuation of one of my earlier posts, which involves the resolving of modules in my WPF application. This question is specifically related to the effect of interdependencies of modules and the method of constructing those modules (i.e. via MEF or through new) on MEF's ability to resolve relationships. First of all, here is a simple UML diagram of my test application: I have tried two approaches: left approach: the App implements IError right approach: the App has a member that implements IError Left approach My code behind looked like this (just the MEF-related stuff): // app.cs [Export(typeof(IError))] public partial class Window1 : Window, IError { [Import] public CandyCo.Shared.LibraryInterfaces.IPlugin Plugin { get; set; } [Export] public CandyCo.Shared.LibraryInterfaces.ICandySettings Settings { get; set; } private ICandySettings Settings; public Window1() { // I create the preferences here with new, instead of using MEF. I wonder // if that's my whole problem? If I use MEF, and want to have parameters // going to the constructor, then do I have to [Export] a POCO (i.e. string)? Settings = new CandySettings( "Settings", @"c:\settings.xml"); var catalog = new DirectoryCatalog( "."); var container = new CompositionContainer( catalog); try { container.ComposeParts( this); } catch( CompositionException ex) { foreach( CompositionError e in ex.Errors) { string description = e.Description; string details = e.Exception.Message; } throw; } } } // plugin.cs [Export(typeof(IPlugin))] public class Plugin : IPlugin { [Import] public CandyCo.Shared.LibraryInterfaces.ICandySettings CandySettings { get; set; } [Import] public CandyCo.Shared.LibraryInterfaces.IError ErrorInterface { get; set; } [ImportingConstructor] public Plugin( ICandySettings candy_settings, IError error_interface) { CandySettings = candy_settings; ErrorInterface = error_interface; } } // candysettings.cs [Export(typeof(ICandySettings))] public class CandySettings : ICandySettings { ... } Right-side approach Basically the same as the left-side approach, except that I created a class that inherits from IError in the same assembly as Window1. I then used an [Import] to try to get MEF to resolve that for me. Can anyone explain how the two ways I have approached MEF here are flawed? I have been in the dark for so long that instead of reading about MEF and trying different suggestions, I've added MEF to my solution and am stepping into the code. The part where it looks like it fails is when it calls partManager.GetSavedImport(). For some reason, the importCache is null, which I don't understand. All the way up to this point, it's been looking at the part (Window1) and trying to resolve two imported interfaces -- IError and IPlugin. I would have expected it to enter code that looks at other assemblies in the same executable folder, and then check it for exports so that it knows how to resolve the imports...
