  • How can I test email generating without creating and checking 1,000 addresses?

    - by twpc
    I am working on generating emails using Java. I would love to use some sort of system where I can send out mass emails and ensure that the emails were received by the intended recipient (A. My code to send the emails worked and B.The emails were not marked as spam). How can I do this without setting up (and keeping track of) a couple hundred email addresses and then checking each one individually? Thanks!

  • 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.

  • .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.

  • What is the best way to generate XML from a C based CGI application using the SQLite API?

    - by Tommy
    Learning the basics of XML for the first time from W3C tutorials. How are most XML files generated? Does the server side application usually print a complete XML file to be parsed each time there is new data? I have a CGI application in C and it includes the SQLite API. Is the best way to do some sort of printf to a XML file (using my data from the database) so it can be parsed? Thanks.

  • 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 ?

  • 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.

  • What does the length attribute do when set on the @Column JPA annontation?

    - by James McMahon
    What exactly does setting the length on a column do in JPA? @Column(name = "middle_name", nullable = false, length = 32) public String getMiddleName() { return this.middleName; } I understand that you can use the annotations to generate the database schema based on the entity objects, but does length do any sort of check or truncation when persistence happens, or it solely used for schema creation? I also realize that JPA can sit on top of various implementations, the implementation I am concerned with in this case, is Hibernate.

  • Why is my CSS overriding the CSS in the Wrapper?

    - by DaveDev
    I'm trying to figure out why the text in the left navigation panel on the following page is shrinking & underlining when you mouseover in Firefox. http://fundcentre.newireland.ie/ Everything on the left & top is part of a wrapper that we inject our content into. Our content is everything from "FUND CENTRE" down. Can someone suggest something I could do to sort this issue out? Thanks.

  • jQuery: How can I work with dates in this format? mm/yyyy

    - by Enrique
    I'm doing a web application for articles Articles must be shown by month, with its published date stored as mm/yyyy Now: 1- Should I use a DATE type field for storing? 2- Will jQuery UI datePicker be useful for showing mm/yyyy? 3- How could I sort by mm/yyyy? I guess it will be more complicated if I store date normally and extract the day from date each time I want to do something, right? Thanks,

  • Execute and Capture one program from another

    - by DandDI
    In win32 programming in C: Whats the best way to execute a win32 console program within another win32 program, and have the program that started the execution capture the output? At the moment I made the program redirect output to a file, but I am sure I must be able to open some sort of pipe?

  • 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.

  • SQL Server Maximum row size

    - by DannySmurf
    Came across this error today. Wondering if anyone can tell me what it means: Cannot sort a row of size 9522, which is greater than the allowable maximum of 8094. Is that 8094 bytes? Characters? Fields? Is this a problem joining multiple tables that are exceeding some limit?

  • 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.

  • 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?

  • 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?

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

    - by Gatis
    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?

  • Is 1-to-n multicast on the open internet reliable?

    - by Jeremy Dunck
    I'm a newbie at networking. I understand the concept of multicast, but was wondering if it's reliable on the open/public internet? It seems like sort of an edge case that different backbones or ISPs might intentionally break to reduce router load or generally segment the network for practical high-use applications. Is my fear reasonable? P.S. Follow-up question here: http://stackoverflow.com/questions/256125/best-tutorial-for-application-multicasting

  • 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?

  • jQuery overlay not working in IE6, Opera

    - by Wild Thing
    Hi, I've been scratching my head for hours trying to figure this out. I have this page: http://173.203.72.190/default.aspx. On clicking 'Any Cuisine', a sort of overlay is supposed to open. It works fine in nearly all browsers except IE6 and Opera. In IE6 and Opera, the jQuery 'overlay' won't open. Anybody have any ideas why this might be?

  • Using routing (?) to make GET request in Rails so ID doesn't show

    - by ale
    I have a link in one view myapp/locations that goes to myapp/statistics?id=1 (statistics for location with ID 1) which works fine but it doesn't look pretty. I think I've seen people do this sort of thing without needing the ?id=1? I could use a POST but this is not RESTful. Is there a way I can use routing to allow the user to go to myapp/statistics?id=1 but have the user see myapp/statistics? Many thanks.
