• Convert an array of primitive longs into a List of Longs

  - by CaptainAwesomePants

  This may be a bit of an easy, headesk sort of question, but my first attempt surprisingly completely failed to work. I wanted to take an array of primitive longs and turn it into a list, which I attempted to do like this: long[] input = someAPI.getSomeLongs(); List<Long> = Arrays.asList(input); //Total failure to even compile! What's the right way to do this?

• .NET Based Radio Automation

  - by Brent Pabst

  I'm curious if anyone has seen an Open Source radio automation package (I found one in Russian on CodePlex) built on .NET In addition if I wanted to build something like this in a client server environment is WCF and WPF the best way to do it? Is it fast enough to trigger songs to play/encode on the server from a remote WPF client? Sort of vague questions but I wanted to get some community feedback.

• Building IronRuby WPF GUIs

  - by Vlad

  This may be a silly question but I was under the impression that it was possible to use IronRuby and MS Visual Studio 2010 together to sort of build interfaces\edit XAML in one window and code ruby in the other? Is this only possible to do with C#, Basic and C++ ? I've browsed SO and seen some IronRuby snippets like this one: button1.click do |sender, args| MessageBox.show("Hello World!") end So it stands to reason you can create GUIs somehow, but is the visual gui creator not available for ironruby?

• Explaining your system to a client

  - by Sir Graystar

  I'm currently developing a small Database Management System for a local company. How would you go about explaining how the system you have designed to a client? If they are non-technical and have no understanding of programming, how would you go about showing what the system will do and how it will do it? I guess some sort of visual representation of the system but this seems very patronising to me.

• Restoring and passing data to an already running instance of a .NET application

  - by mtranda

  The goal is to have an application that runs in the system tray and can either accept user input from its actual GUI (which isn't the actual issue) OR accept command line parameters (that would actually be done via a context menu in windows explorer). Now, while I'm aware that the command line parameters are not exactly possible once the application has started, I need a way to pass data to the already running application instance via some form of handler. I'm thinking maybe define and raise some sort of event? Thanks in advance.

• Data access layer using Linq to SQL

  - by Andrei Tanasescu

  I am building a c# - linq - sql server winforms/asp.net application, accessing a database. I would like my business logic layer to be easily testable, and that means not littering it with Linq database queries everywhere. What design patterns/ best practices are available for the following use cases - inserting/updating a new object - searching for an object - loading a bunch of related data into a sort of "presentation" object that could be displayed by various views ?

• Is there an existing delegate in the .NET Framework for comparison?

  - by Neil Barnwell

  The .NET framework provides a few handy general-use delegates for common tasks, such as Predicate<T> and EventHandler<T>. Is there a built-in delegate for the equivalent of CompareTo()? The signature might be something like this: delegate int Comparison<T>(T x, T y); This is to implement sorting in such a way that I can provide a lambda expression for the actual sort routine (ListView.ListViewItemSorter, specifically), so any other approaches welcome.

• How to show number of jgrowl notfications?

  - by chobo2

  Hi I am using a pool of 5 with jquery. So only 5 notifications should be shown. I think it would be nice to have maybe under the "close all" button to have a count like shown 5 of 20 notifications. To me it could get confusing if I keep closing notifications and new ones keep poping up. I might think there is some sort of problem with the site. Anyone know how to do this?

• Python - How is this snippet working?

  - by orokusaki

  For some reason this function confused me: def protocol(port): return port == "443" and "https://" or "http://" Can somebody explain the order of what's happening behind the scenes to make this work the way it does. I understood it as this until I tried it: Either A) def protocol(port): if port == "443": if bool("https://"): return True elif bool("http://"): return True return False Or B) def protocol(port): if port == "443": return True + "https://" else: return True + "http://" Is this some sort of special case in Python, or am I completely misunderstanding how statements work?

• How to implement a login page in a GWT app?

  My WebApp needs to authenticate user before allowing any sort of access. The scenario I'm trying to implement is a login page with username and password fields. Once user hits "send" button, a sign like "Verifing..." should be shown up while an RPC call verifies credentials. In case of success, load the main app screen. What is the best way to implement that?

• How do you retrieve a list of logged-in/connected users in .NET?

  - by Engram

  Here's the scenario: You have a Windows server that users remotely connect to via RDP. You want your program (which runs as a service) to know who is currently connected. This may or may not include an interactive console session. Please note that this is the not the same as just retrieving the current interactive user. I'm guessing that there is some sort of API access to Terminal Services to get this info?

• How would you convert a String to a Java string literal?

  - by Simon Nickerson

  This is sort of the Java analogue of this question about C#. Suppose I have a String object which I want to represent in code and I want to produce a string literal that maps to the same thing. I was just about to write a state machine that ingests the string character by character and escapes appropriately, but then I wondered if there was a better way, or a library that provides a function to do this.

• Subversion Deployment tools: specify branch/tag, revision and target machine

  - by Terman

  What are some non commercial deployment tools that allows a developer to speficy: a branch/tag, a revision and a target machine to deploy code to? I was wondering if there's a ccnet plugin of some sort that would allow the above to be specified. I know this could be done with a NAnt deploy script. However considering we're mostly using gui tools for feedback, plus the tortoise svn repository browser, it be cool to lear if there's an GUI simple GUI tool/plugin cheers.
