  • Is it possible to set a default behaviour for custom (non-native) methods/functions in Java?

    - by Tom
    Is it possible to set a default behaviour for custom (non-native) methods/functions in Java? For example, I would like to change the default "Function" to do a System.out.println("message") whenever called. So, when a custom method/function is being created: public String testMethod() { //custom code } it should execute the newly added default behaviour (in this case the system output), before the custom code is run. Even if this would be a bad excercise, is it possible? Maybe by extending the function class or something?

  • Restricting access to records. Is claim-based permissions a good idea.

    - by Vitalik
    in .net Claim-based identity framework If i wanted to restrict users to do an operation (view or edit) on let's say an account, a particular account #123456.(i am talking about business entity, like a bank account.) Is it a good idea to create a claim for each account they can view or edit? Any disadvantages of having a lot of claims in a set? a system admin might have access to all accounts in the system thus creating hundreds of claims (maybe more than one for each account)

  • Reasons against using "Git" in the enterprise.

    - by Zubair
    I was recently using a commercial centrally controlled version control system in a large company with about 100 different subsystems written in different operating systems and languages, and I have noticed that several developers use either git or mercurial on their pet projects, but not for their work systems. I personally am more familiar with git but was wondering what reasons are their to "Not" use Git in the enterprise, apart from the fact that the choice has already been made (we have many problems with our centrally controlled version system, so I can't say it is brilliant).

  • Convert HTML to RTF (HTML2RTF converter)

    - by Luca Matteis
    I'm looking for a simple HTML2RTF converter that I can use on my website which is using a *nix like Operating System. I haven't found anything on the internet, and was hoping the SO community would help me. PS: I don't want to implement this from scratch, and it doesn't really matter what language it's in, as long as I can run it on a *nix like system. If you guys have already some personalized implementation, the language preferred would be PHP.

  • How to suppress warnings in external headers in Visual C++

    - by Bob Whiteman
    I'm starting a new BREW project, and I'd like to compile with Warning Level 4 (/W4) to keep the application code nice and clean. The problem is that the BREW headers themselves don't compile cleanly with /W4. In gcc you can differentiate between application and system headers by using -I and -isystem, and then by default gcc doesn't report any compilation warnings in system headers. Is there an equivalent mechanism in Visual C++?

  • DLL configuration file in asp.net site

    - by Tominator
    Hi, I've made a .net 2.0 librabry project, that results in a dll. I've made an app.config file in my project, with settings used in the dll, with the intention that they can be changed later. I'm attempting to use the dll in an asp.net web application now, so I made the reference to my other project's output, and I see that the dll is copied over to the site's bin folder, and everything works. However, the configuration file is not copied. When I manually copy the app.config and rename it to myDll.config, it has no influence. The contents of the config file is approximately this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="myDLL.My.MySettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </sectionGroup> </configSections> <applicationSettings> <myDLL.My.MySettings> <setting name="myDLL_webservice_Service" serializeAs="String"> <value>https://myhost/Service.asmx</value> </setting> <setting name="ID" serializeAs="String"> <value>6</value> </setting> </myDLL.My.MySettings> </applicationSettings> </configuration> And I use its settings in the dll with this (vb.net code): Private _id As Long = My.Settings.ID How can I put my config information somewhere so it can be used? In the web.config of the site application? That has only the appSettings section, and it uses the syntax. It doesn't appear to work though. In a custom file format that I create and use? Not that pretty..

  • Passing ViewModel for backbone.js from MVC3 Server-Side

    - by Roman
    In ASP.NET MVC there is Model, View and Controller. MODEL represents entities which are stored in database and essentially is all the data used in a application (for example, generated by EntityFramework, "DB First" approach). Not all data from model you want to show in the view (for example, hashs of passwords). So you create VIEW MODEL, each for every strongly-typed-razor-view you have in application. Like this: using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace MyProject.ViewModels.SomeController.SomeAction { public class ViewModel { public ViewModel() { Entities1 = new List<ViewEntity1>(); Entities2 = new List<ViewEntity2>(); } public List<ViewEntity1> Entities1 { get; set; } public List<ViewEntity2> Entities2 { get; set; } } public class ViewEntity1 { //some properties from original DB-entity you want to show } public class ViewEntity2 { } } When you create complex client-side interfaces (I do), you use some pattern for javascript on client, MVC or MVVM (I know only these). So, with MVC on client you have another model (Backbone.Model for example), which is third model in application. It is a bit much. Why don`t we use the same ViewModel model on a client (in backbone.js or another framework)? Is there a way to transfer CS-coded model to JS-coded? Like in MVVM pattern, with knockout.js, when you can do like this: in SomeAction.cshtml: <div style="display: none;" id="view_model">@Json.Encode(Model)</div> after that in Javascript-code var ViewModel = ko.mapping.fromJSON($("#view_model").get(0).innerHTML); now you can extend your ViewModel with some actions, event handlers, etc: ko.utils.extend(ViewModel, { some_function: function () { //some code } }); So, we are not building the same view model on the client again, we are transferring existing view model from server. At least, data. But knockout.js is not suitable for me, you can`t build complex UI with it, it is just data-binding. I need something more structural, like backbone.js. The only way to build ViewModel for backbone.js I can see now is re-writing same ViewModel in JS from server with hands. Is there any ways to transfer it from server? To reuse the same viewmodel on server view and client view?

  • C# .net updates versus compile time debugging. How to stop the oddities?

    - by Fox Diller
    Are we reduced to ClickOnce to manage our application state for our users? We use Visual Patch currently. When our users update (we reproduced this) we get errors from the updated versions to our compiled versions. Since our developer state is not 'updated' with Visual Patch how can we monitor and eventual squash the various System.MethodNotFound, and System.NullReferenceException in our updated versions of our application?

  • How do I rename a process on Linux?

    - by jemfinch
    I'm using Python, for what it's worth, but will accept answers in any applicable language. I've tried writing to /proc/$pid/cmdline, but that's a readonly file. I've tried assigning a new string to sys.argv[0], but that has no perceptible impact. Are there any other possibilities? My program is executing processes via os.system (equivalent to system(3)) so a general, *NIX-based solution using an additional spawning process would be fine.
