  • How to get hudson to display the SCM diff since last build in the individual build page

    - by Steen
    I'm not sure it's even possible, but my command line usecase goes something like this: do svn update do a svn log -l {how many times since my last commit - 1} do a `svn diff -rHEAD:{my last commit revision + 1} and try to get an overview of what happened since last time I touched the code. I get a lot of valuable information from this, and would like everybody in my team to get the same feeling of control and overview of the code base. Not everyone in my team is comfortable with the command line but like the hudson interface. So; is there a way to the the commit diff since last build (we do a build per commit) in the individual build page?

  • trying to use ActiveRecord with Sinatra, Migration fails question

    - by David Lazar
    Hi, running Sinatra 1.0, I wanted to add a database table to my program. In my Rakefile I have a task task :environment do ActiveRecord::Base.establish_connection(YAML::load(File.open('config/database.yml'))["development"]) end I have a migration task in my namespace that calls the migration code: namespace :related_products do desc "run any migrations we may have in db/migrate" task :migrate => :environment do ActiveRecord::Migrator.migrate('db/migrate', ENV["VERSION"] ? ENV["VERSION"].to_i : nil ) end My console pukes out an error when the call to ActiveRecord::MIgrator.migrate() is made. rake aborted! undefined method `info' for nil:NilClass The migration code itself is pretty simple... and presents me with no clues as to what this missing info class is. class CreateStores < ActiveRecord::Migration def self.up create_table :stores do |t| t.string :name t.string :access_url t.timestamps end end def self.down drop_table :stores end end I am a little mystified here and am looking for some clues as to what might be wrong. Thanks!

  • Free Testing / Code Coverage systems for C++

    - by Billy ONeal
    I'd like to start using a Test Driven Development system for a private project since I saw my employer using it and realized it was very useful. My employer's project was in C# but mines are in C and C++. I looked around and saw that several packages exist for both Java and .NET (for example: NCover, NUnit, ...). Unfortunately I found it difficult to find good C++ testing frameworks. Do you know of any unit testing frameworks that satisfy the following requirements? IMPORTANT: Must provide code coverage statistics, as I'd like to have some idea of how well my tests cover my code-base. Must be free Usable with C++ projects EDIT: To be clear, I know of many existing unit test frameworks. The code coverage piece is what's most important.

  • Why my custom CStatic derived control does not receive WM_SIZE message?

    - by Michael P
    Hello everyone! I'm currently developing a custom control that derives from CStatic MFC class (Smart Device C++ project). I have created the control class using VC++ MFC class wizard, selecting CStatic class as its base class. I have used Class View to add OnSize event handler for my control class (I have selected WM_SIZE message from messages list), and new OnSize method has been created by Visual Studio along with ON_WM_SIZE() statement between BEGIN_MESSAGE_MAP(...) and END_MESSAGE_MAP(). The problem is that my control does not receive WM_SIZE thus OnSize method is never called - I used MoveWindow to change size of my control - its size changes as I have seen on dialog window but WM_SIZE message is never being sent. When I send WM_SIZE through SendMessage or PostMessage function - the control OnSize method is called normally. What do I wrong? I've read MSDN docs about CStatic control and there is no information that WM_SIZE message is never sent to a static control window. Sorry for my bad English.

  • How would I detect horizontal-black lines using ImageMagick?

    - by Zando
    So I have what is essentially a spreadsheet in TIFF format. There is some uniformity to it...for example, all the column widths are the same. I want to de-limit this sheet by those known-column widths and basically create lots of little graphic files, one for each cell, and run OCR on them and store it into a database. The problem is that the horizontal lines are not all the same height, so I need to use some kind of graphics library command to check if every pixel across is the same color (i.e. black). And if so, then I know I've reached the height-delimiter for a cell. How would I go about doing that? (I'm using RMagick)

  • Android: How to find the position clicked from the context menu

    - by Josemalive
    Hi, I have a list view filled with data. I set up a context menu for the listview using the following code: list.setOnCreateContextMenuListener ( new View.OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu menu, View view, ContextMenu.ContextMenuInfo menuInfo) { AdapterContextMenuInfo mi =(AdapterContextMenuInfo) menuInfo; menu.add(0, 0, 0, "Delete item"); } } ); I have the following method override to control de contextmenu menuitem selected: @Override public boolean onContextItemSelected(MenuItem item) { switch(item.getItemId()) { case 0: ShowAlert("hello from delete item"); break; default: return super.onContextItemSelected(item); } return true; } In this overrided method, how could i find the item of the list view that was clicked? Thanks in advance. Best Regards. Jose

  • Delay after pressing a button

    - by KrLx_roller
    After I press a button, Android parse a JSON file and pick the info it needs. Until yesterday, I was using an external library created by a user and it worked perfectly. But now, I don't want to depend on him, so I've searching info about Google's GSON. I've implemented this library with no problem, but now, after pressing the button that opens a new activity there's a delay. This delay is due to the connection and parsing that are done before the activity shows. How can I force the app to wait the Internet connection until de Activity is shown? It's a lil bit uncomfortable because after pressing the button, it seems that the app has frozen, but after all data is loaded, the new activity appears. Thank you in advance!

  • Double Negation in C++ code.

    - by Brian Gianforcaro
    I just came onto a project with a pretty huge code base. I'm mostly dealing with C++ and a lot of the code they write uses double negation for their boolean logic. if (!!variable && (!!api.lookup("some-string"))) { do_some_stuff(); } I know these guys are intelligent programmers, it's obvious they aren't doing this by accident. I'm no seasoned C++ expert, my only guess at why they are doing this is that they want to make absolutely positive that the value being evaluated is the actual boolean representation. So they negate it, then negate that again to get it back to its actual boolean value. Is this a correct? or am I missing something else? Thanks, Brian Gianforcaro

  • Xap file contents changes if built in Visual Studio or build server

    - by arch
    I'm using MEF with my Silverlight 4 app to dynamically load xap files. To optimize this process, I've removed various assemblies from my xaps since I know they've already been loaded by the base xap. This reduces the size of my dynamically loaded xaps. I accomplished this by setting the "Copy Local" flag for each assembly reference to "false". This all seems to work fine when I build in Visual Studio 2010 - my xaps are much smaller. However, when the same projects are built by the build server, all the excluded references are once again in the xap file hence tripling the size of the xap. I've read several blogs/articles regarding similar experiences but no resolution. Very frustrating - any help is appreciated.

  • Can I make DataGridView.EndEdit trigger the CellValidating event?

    - by Don Kirkby
    I'm using a DataGridView in my WinForms application. My main objective is to make the Enter key not move to the next row in the grid. I still want the enter key to validate and end edit mode. I found this FAQ entry and subclassed DataGridView to override ProcessDialogKey(). If the key pressed is Enter, I call EndEdit(), otherwise I call base.ProcessDialogKey(). It works great, except the CellValidating event isn't fired. Currently, I'm just manually calling my validation logic before I call EndEdit, but it seems like I'm missing something. I guess I could call OnCellValidating, but then I'd be worried I'm missing some other event. What I really want is some flavour of EndEdit() that behaves just like pressing enter on the last row of a grid with adding disabled.

  • executing named_scoped only when there are present params

    - by Luca Romagnoli
    Hi have a model like this: class EventDate < ActiveRecord::Base belongs_to :event named_scope :named, lambda { | name | { :joins => { :event => :core}, :conditions => ["name like ?", "%#{ name }%"] }} named_scope :date_range, lambda { | start, length | { :conditions => ["day >= ? AND day <= ?", start, date + (length || 30) ] }} it works correctly if i launch name = "ba" start = Date.today EventDate.named(name).date_range(start , start + 2) But if the name or the start is nil i don't want execute the named_scope like name = nil EventDate.named(name).date_range(start , start + 2) Is possible to set a condition inner the named_scope ? thanks

  • LogCat acting patchy

    - by OceanBlue
    The LogCat output in eclipse suddenly started weird. It sometimes shows all the output as expected. Other times it just doesn't show anything - is completely blank. After some internet research, I thought Mylyn plugin might be responsible. So I tried de-selecting "Mylyn Tasks UI" & "Mylyn Team UI" on eclipse Window -- Preferences -- General -- Startup and Shutdown -- programs that are started at startup. No Luck. Has anyone else encountered & solved this problem?

  • where should I put the EF entity and data annotations in asp.net mvc + entity framework project

    - by giddy
    So I have a DataEntity class generated by EntityFramework4 for my sqlexpress08 database. This data context is exposed via a WCF Data Service/Odata to silverlight and win forms clients. Should the data entities + edmx file (generated by EF4) go in a separate class library? The problem here then is I would specify data annotations for a few entities and then some of them would require specific MVC attributes (like CompareAttribute) so the class library would also reference mvc dlls. There also happen to be entity users which will be encapsulated or wrapped into an IIdentity in the website. So its pretty tied to the mvc website. Or Should it maybe go in a Base folder in the mvc project itself? Mostly the website is data driven around the database, like approve users, change global settings etc. The real business happens in the silverlight and win forms apps. Im using mvc3 rc2 with Razor. Thanks

  • Useful ways for multilanguage navigation and static content on your site?

    - by vitto
    Hi, I have a big site running under Apache and PHP and in few mounths I should consider to add some different language version of it, but I'm not sure about the right way (or ways). My problem it isn't the user data, because I can use db tables with different languages (en, de, it, etc.) so I want concentrate my answer on navigation and static content. For now I can't use gettext because I don't have a dedicated server and I can't reboot it every time I want, but surely will be a future choice. So my main problems are these: In the site, I have classical XHTML elements like the menus, lists, div and various static texts in various pages (should be perferct for gettext, but I need a alternative) The other part of the sites has XHTML elements which are dynamically created via AJAX and jQuery, and here I haven't any idea of what can I do... So does exists some example I can see in some link to solve it (or some useful tecnique)?

  • Set Window Properties based on Datatype of UserControl

    - by Kage
    I've got a simple window, that is container for various views. I've got a DataTemplate that shows the correct view based on whatever the window's MainViewModel property is set to. <DataTemplate DataType="{x:Type VM:StartupViewModel}"> <AdornerDecorator> <V:StartupView /> </AdornerDecorator> </DataTemplate> What I'd like to do is for certain views, change some properties on the base window, ie WindowStyle, ResizeMode etc. something like triggers, but on datatypes instead of property values? How could I accomplish this?

  • Any implementations of graph st-ordering or ear-decomposition?

    - by chang
    I'm in the search for an implementation of an ear-decomposition algorithm (http://www.ics.uci.edu/~eppstein/junkyard/euler/ear.html). I examined networkx and didn't find one. Although the algorithm layout is vaguely in my mind, I'd like to see some reference implementation, too. I'm aware of Ulrik Brandes publication on a linear time Eager st-ordering algorithm, which results in an ear decomposition as a side product, if I understand correctly (it even includes pseudocode, which I'm trying to base my implementation on). Side problem: First step could be an st-ordering of a graph. Are there any implementations for st-ordering algorithms you know? Thanks for your input. I'd really like to contribute e.g. to networkx by implementing the ear-decomposition algorithm in python.

  • How can I share Configuration Settings across multiple projects in Visual Studio?

    - by Muneeb
    Ok I know this may be a design issue, so I would love to have remarks on that as well. I have a Visual Studio web application solution. I have three projects as UserInterface, BusinessLogic and DataAccess. I had to store some user defined settings and I created configSections in the config file. I access these configSections through classes which inherit from .NET's ConfigurationSection base class. So in short for every project I had a separate configSection and for that corresponding configSection I had a class in that project inheriting from ConfigurationSection to access the config section settings. This works all sweet. But the problem arises if there is any setting which I need to use across multiple projects. So If I need to use a setting defined in UserInterface project configSection in, let say, BusinessLogic project I have to actually make a copy of that setting in the BusinessLogic's configSection. This ends up having the same setting copied across multiple configSections. Isn't this a bit too redundant?

  • Switching/Linking to another external stylesheet in a .js file using Ruby on Rails

    - by Jake
    Im learning JQuery from a Sitepoint Book but Im trying to apply all the lessons to a Rails App. In one lesson, we are taught how to switch to a different stylesheet if the browser window is resized beyond a certain point. Here's the javascript code: if ($('body').width() > 900) { $('<link rel="stylesheet" href="wide.css" type="text/css" />') .appendTo('head'); } else { $('link[href=wide.css]').remove(); } Rails doesn't seem to want to link to the new stylesheet using 'link rel'. I've tried using the Rails helper: <%= stylesheet_link_tag 'base', :media => 'screen' %> but that doesn't work in a .js file. How do I link to an external stylesheet in a .js file using Ruby? Can I use Ruby on Rails code in a .js file? Thanks.

  • Does the WCF framework support the XSD IDREF restriction?

    - by Gerard
    A nice feature in XSD is the IDREF restriction, e.g.: <xs:restriction base="xs:IDREF"> <xs:pattern value="[0-9a-zA-Z\-]+"/> </xs:restriction> I used this restriction with great benefit in a Java JAXWS-project. An object serialized in a SOAP XML datamodel can hold a reference (pointer) to another object in the same SOAP message. I want to try the same approach in a C# WCF-project, can it be done? On the web site Data Contract Schema Reference I can see e.g. Id ignored, Ref forbidden, but I am not sure whether I understand what that means.

  • How to change a Datasource's username/password at runtime in a J2EE app?

    - by Toto
    I've deployed a web-module which connects to the database via a datasource configured in the J2EE application server. Currently, the user/password for the database connection is set in the proper J2EE application server's datasources configuration file. I want to change during runtime the datasource's user/password. (e.g.: implement a new web form in which the user is asked to enter de user/password to be used in the database connection). Is there a standard way to do that in J2EE applications or it depends on the J2EE application server? In this case I'm using Orion application server.

  • Caesar Cipher in Java (Spanish Characters)

    - by Rodolfo
    I've reading this question, and I was wondering if Is there any way to consider the whole range of characters? For example, "á", "é", "ö", "ñ", and not consider " " (the [Space])? (For example, my String is "Hello World", and the standard result is "Khoor#Zruog"; I want to erase that "#", so the result would be "KhoorZruog") I'm sure my answer is in this piece of code: if (c >= 32 && c <= 127) { // Change base to make life easier, and use an // int explicitly to avoid worrying... cast later int x = c - 32; x = (x + shift) % 96; chars[i] = (char) (x + 32); } But I've tried some things, and it didn't work.

  • How do I initialize attributes when I instantiate objects in Rails?

    - by nfm
    Clients have many Invoices. Invoices have a number attribute that I want to initialize by incrementing the client's previous invoice number. For example: @client = Client.find(1) @client.last_invoice_number > 14 @invoice = @client.invoices.build @invoice.number > 15 I want to get this functionality into my Invoice model, but I'm not sure how to. Here's what I'm imagining the code to be like: class Invoice < ActiveRecord::Base ... def initialize(attributes = {}) client = Client.find(attributes[:client_id]) attributes[:number] = client.last_invoice_number + 1 client.update_attributes(:last_invoice_number => client.last_invoice_number + 1) end end However, attributes[:client_id] isn't set when I call @client.invoices.build. How and when is the invoice's client_id initialized, and when can I use it to initialize the invoice's number? Can I get this logic into the model, or will I have to put it in the controller?

  • ordering an acts_as_tree relationship

    - by timpone
    I have a Category class that is defined like this: class Catergoy < ActiveRecord::Base acts_as_tree :parent_id I'd like the ordering to be by the position value which is a float such that: category-1 category-2, parent_id=1, position=0.5 category-3, parent_id=2, category-4, parent_id=1, position=1 How would I specify this? I tried acts_as_tree :parent_id :order => :position acts_as_tree :parent_id, :order => :position but these are not working. Any ideas how to specify this relationship? Or if I'm missing something else? thx in advance

  • How change Subversion's default binary mime-type?

    - by lamcro
    Subversion sets a binary file's svn:mime-type property to application/octet-stream by default. I need to change this default to some other mime-type. When I import for the first time this code, I would like Subversion to set mime-type to the one I choose. The reason is that my code base contains code in binary files (proprietary format), and I have the applications necessary to emulate diff and diff3 for these. But Subversion does not let me due to their default mime-type. Please note: There is no default extension (*.jar, *.py, etc) for these code files. Some files don't even have an extension. So configuring mime-type by file extension is not possible.
