• service repository.

  - by SteveCav

  hundreds of our clients around the country have a vb6/MS Access app. The boss needs them to talk to each other, eg client A creates a new task in client B's database, and status updates go back to A. I'm trying to design a WCF system that can accomplish this using a centralized service talking to a service of some kind installed on each client. What I'm wondering is, how the central system knows the address of the clients, ie determine and consume services on the fly? What's a good architecture to fit these requirements?

• Is there a way to synchronize sections of different Word documents? Alternatives?

  - by David Hodgson

  Hi, I'm working on how my company does documentation (especially programming documentation). I'd like to be able to synchronize sections of different Word documents, such that if a section in one document changes, the change is reflected in the other document, and vice versa. Is there a way to do this with Word, and if not, is there some word processing program that is good at this?

• pure as3 benefits to compiling with flex4 instead of flex3?

  - by jedierikb

  If I have a pure as3 project that I have been compiling with flex3 from mxmlc, is there any reason to switch to using the mxmlc with flex4? I can use all of the flash 10 language features like Vector, 3D, etc., so that is not a reason to switch (or is there something I can't do?). But maybe there is a performance boost? Or is the exact same compiling tool and the flex code base is the only difference?

• Rails - How do you test ActionMailer sent a specific email in tests

  - by adam

  Currently in my tests I do something like this to test if an email is queued to be sent assert_difference('ActionMailer::Base.deliveries.size', 1) do get :create_from_spreedly, {:user_id => @logged_in_user.id} end but if i a controller action can send two different emails i.e. one to the user if sign up goes fine or a notification to admin if something went wrong - how can i test which one actually got sent. The code above would pass regardless.

• Create an upload form, select a folder and get a specific file in folder

  - by aladine

  Hi, To upload a single file, it is very simple to use this HTML script: <p> <input type="file" name="input.txt" /> In this question, my task is to select a folder and then get the input.txt inside that folder. The server will response whether input.txt is available or not and to upload it to web server. Is there any way to select a folder instead selecting a file in the input form. Thanks.

• With Ruby, where to use NOT, AND, OR, XOR operations for Fixnum or Bignum?

  - by Jason

  Hi, Just wondering if anyone has any realworld examples or know when you might use the NOT, AND, OR, XOR, <<, operators in Ruby. I've been programming for 4 years and never come across the need to use any of these, wondering how common actual usage is & if its something I should fully understand. Thanks, -J

• Is there a way to create a step chart using the Google Charts API?

  - by Nathan

  I'd like to use the google charts API to create a step chart for my Rails application. Preferably using the annotated timeline Google has (since it has a nice wrapper plugin for rails): http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html However, there doesn't seem to be a way to create a step chart using the annotated timeline or any other chart in the Google API. I'm looking to make a plot like this: If there is no way to do this with the google API, is there an alternative graphing library that can handle such a task?

• How could I get an .ear's filesize at runtime?

  - by adam

  I started out attempting to do this with the Length ant task, but realized that that would be done before the ear is packaged. Packaging the ear, then checking the file size, and then placing it in the ear would effect the size of the ear. Is there a way to get the ear's size programmatically at run-time? Or perhaps an MBean that would have that information?

• Show a DB as a directory (Like Sharepoint Does)

  - by Zyd

  Hi, My team and I are programming a sort of Document Manager and the idea is to store them completely on DB. Is there a protocol or Extensions that allows us to show a "Virtual Directory" or files that are really non existent (only in DB). How does Sharepoint do this? I understand that Sharepoint uses WebDav but it implies that the files do exist physically somewhere. We intend to develop this application on .NET 4.0 and deploy it on IIS. Any suggestions? Thanks in advance

• Objects With No Behavior

  - by Patrick Donovan

  I've been teaching myself object oriented programming and I'm thinking about a situation where I have an object "Transaction", that has quite a few properties to it like account, amount, date, currency, type, etc. I never plan to mutate these data points, and calculation logic will live in other classes. My question is, is it poor Python design to instantiate thousands of objects just to hold data? I find the data far easier to work with embedded in a class rather than trying to cram it into some combination of data structures.

• ActiveRecord: Produce multi-line human-friendly json

  - by Mika

  Using ActiveRecord::Base.to_json I do: user = User.find_by_name 'Mika' {"created_at":"2011-07-10T11:30:49+03:00","id":5,"is_deleted":null,"name":"Mika"} Now, what I would like to have is: { "created_at":"2011-07-10T11:30:49+03:00", "id":5, "is_deleted":null, "name":"Mika" } Is there an option to do this? It would be great to have a global option, so that the behaviour be set depending on dev/live environment.

• Is there a decent HTML Junit report plugin for Maven?

  - by cats2ndlife

  I find the surefire-report plug-in very unsuitable to my working style. I clean the project all the time and I don't want to spend 5 min to rebuild the whole site every time I want to look at the test report in my browser. If I type mvn surefire-report:report-only, the generated report is too ugly and barely readable. What I'm looking for is something like ant's JUnitReport task. Is there one available out there already?

• Is there a substitute for blockproc in Matlab?

  - by SetchSen

  I've been using blockproc for processing images blockwise. Unfortunately, blockproc is part of the Image Processing Toolbox, which I don't have on my personal computer. Is there a combination of functions in base Matlab that can substitute for blockproc? My initial guess was to use im2col to transform each block into columns, and then arrayfun to process each column. Then I realized that im2col is also a part of the Image Processing Toolbox, so that doesn't solve my problem.

• How can I pass managed objects from one AppDomain to another?

  - by Dennis P

  I have two assemblies that I'm trying to link together. One is a sort of background process that's built with WinForms and will be designed to run as a Windows Service. I have a second project that will act as a UI for the background process whenever a user launches it. I've never tried attempting something like this with managed code before, so I've started trying to use windows messages to communicate between the two processes. I'm struggling when it comes to passing more than just IntPtrs back and forth, however. Here's the code from a control in my UI project that registers itself with the background process: public void Init() { IntPtr hwnd = IntPtr.Zero; Process[] ps = Process.GetProcessesByName("BGServiceApp"); Process mainProcess = null; if(ps == null || ps.GetLength(0) == 0) { mainProcess = LaunchApp(); } else { mainProcess = ps[0]; } SendMessage(mainProcess.MainWindowHandle, INIT_CONNECTION, this.Handle, IntPtr.Zero); } protected override void WndProc(ref Message m) { if(m.Msg == INIT_CONFIRMED && InitComplete != null) { string message = Marshal.PtrToStringAuto(m.WParam); Marshal.FreeHGlobal(m.WParam); InitComplete(message, EventArgs.Empty); } base.WndProc(ref m); } This is the code from the background process that's supposed to receive a request from the UI process to register for status updates and send a confirmation message. protected override void WndProc(ref Message m) { if(m.Msg == INIT_CONNECTION) { RegisterUIDispatcher(m.WParam); Respond(m.WParam); } if(m.Msg == UNINIT_CONNECTION) { UnregisterUIDispatcher(m.WParam); if(m_RegisteredDispatchers.Count == 0) { this.Close(); } } base.WndProc(ref m); } private void Respond(IntPtr caller) { string test = "Registration confirmed!"; IntPtr ptr = Marshal.StringToHGlobalAuto(test); SendMessage(caller, INIT_CONFIRMED, ptr, IntPtr.Zero); } } The UI process receives the INIT_CONFIRMED message from my background process, but when I try to marshal the IntPtr back into a string, I get an empty string. Is the area of heap I'm using out of scope to the other process or am I missing some security attribute maybe? Is there a better and cleaner way to go about something like this using an event driven model?

• Calculate broadcast address given IP address and subnet in PowerShell

  - by halr9000

  My goal is to calculate the broadcast address when given the IP and subnet mask of a host node. I know, sounds like homework. Once I reasoned through my task and boiled it down to this, I was amused with myself. Anyway, the solution will look something like the one in this question I suppose, but I'm not a math major and my C sucks. I could do with a PowerShell (preferred) or C# example to get me going. thanks!

• Web development - relative URLs without duplicating files

  - by eshriek

  I have a site with index.php in the root folder, images in /img , and overview.php in /content . I have a sidebar.php file that is included in both index.php and overview.php . How should I refer to /img/image.gif if I include a link in each file? The location of image.gif changes relative to the location of the file that references it. Using /img/image.gif in sidebar.php will work in index.php, but it fails for the file located at /content/overview.php. The only solution that I can see is to either include a seperate sidebar.php in each subdirectory, or include an /img directory in every sub-directory. The best suggestion that I can find is to use the <base html tag as suggested here: Change relative link paths for included content in PHP However, in the same link, SamGoody suggests that the <base tag "is no longer properly supported in Internet Explorer, since version 7." I'd like some insight on the matter before committing to a course of action. Thanks. EDIT: I am using the wrong approach below with "../" Example- root/index.php: ... <link rel="stylesheet" type="text/css" href="style.css" /> <title>title</title> </head> <body> <?php include('include/header.php'); ?> <?php include('include/menu.php'); ?> ... root/include/header.php: ... <div id="header"> <span class="fl"><img src="img/dun1.png"/></span><span class="fr"><img src="img/dun2.png"/></span> ... root/content/overview.php: ... <link rel="stylesheet" type="text/css" href="../style.css" media="screen" /> <title>Overview</title> </head> <body> <?php include('../include/header.php'); ?> <?php include('../include/menu.php'); ?> ...
