• Comparison of Code Review Tools/Systems

  - by SytS

  There are a number of tools/systems available aimed at streamlining and enhancing the code review process, including: CodeStriker Review Board, code review system in use at VMWare Code Collaborator, commercial product by SmartBear Rietveld, based on Modrian, the code review system in use at Google Crucible, commercial product by Atlassian These systems all have varying feature sets, and differ in degrees of maturity and polish; the selection is a little bewildering for someone who is evaluating code review systems for the frist time. Some of these tools have already been mentioned in other questions/answers on StackOverflow, but I would like to see a more comprehensive comparison of the more popular systems, especially with respect to: integration with source control systems integration with bug tracking systems supported workflow (reviews pre/post commit, review or contiguous/non-contigous revision ranges, etc) deployment/maintenance requirements

• Tracking graphics tablet input in C#

  - by Martin

  I'm writing an XNA application with C#, and I want to be able to control the application with a graphics tablet. All I need to be able to do is track the position and pressure of the pen on the tablet, it would be nice to have some built in gesture recognition but I'm willing to build that myself if needed. My first attempt at this was to use the vbtablet library. However, when I sent this to a friend it failed to work. It seems that the underlying technology is quite old and not supported by some tablets. My second attempt is to play with the Microsoft.Ink system. This looks promising, but I know very little about this subject and I'm struggling to make it work properly - for example I can't find how to read the raw tablet input and disable mouse pointer mode on the tablet when using an InkOverlay. What's the best system to use and what good documentation is there for a beginner in this field?

• Popularity of Git/Mercurial/Bazaar vs. which to recommend

  - by Will Robertson

  Going by the number of questions on this site for these three distributed version control systems, it seems like Git either is more popular, or is more difficult (hence requiring more questions), or has more features (hence requiring more questions). Or most probably a combination of the three. (Let's say that popularity on this site equates to popularity at large.) Here are the numbers at time of writing: [subversion] or [svn]: 2353 [git]: 726 [mercurial] or [hg]: 169 [bazaar] or [bzr]: 50 The recent historical popularity of Subversion is clearly reflected by the number of questions, indicating at least a small tipping of the scales towards Git over the Mercurial or Bazaar. It's not entirely satisfactory having three competing yet largely equivalent open source products to choose from. Personally I use Git and I'm fine with the other two. But when it comes to recommending one system over the others, I'd like to ask: can we start recommending one safely yet?

• Is there a way to generate a gitignore from a makefile?

  - by Kinopiko

  I have a lot of files such as JavaScript, HTML, and even C and C header (.h) files which are automatically generated, so they appear in the makefile like myfile.js: myfile.js.tmpl etc. I want all of these target files to be ignored by the version control system. I am using git but this question is not git-specific. Is there a utility or a trick which exists to make the ignore file (like .gitignore) from a makefile? (If there isn't such a facility, I can make a script to create one, but before I do that I am just checking I haven't missed some obvious tool or method.)

• Silverlight 4 race condition with DataGrid master details control

  - by Simon_Weaver

  Basically I want a DataGrid (master) and details (textbox), where DataGrid is disabled during edit of details (forcing people to save/cancel)... Here's what I have... I have a DataGrid which serves as my master data. <data:DataGrid IsEnabled="{Binding CanLoad,ElementName=dsReminders}" ItemsSource="{Binding Data, ElementName=dsReminders}" > Its data comes from a DomainDataSource: <riaControls:DomainDataSource Name="dsReminders" AutoLoad="True" ... I have a bound Textbox which is the 'details' (very simple right now). There are buttons (Save/Cancel) which should be enabled when user tries to edit the text. Unfortunately Silverlight doesn't support UpdateSourceTrigger=PropertyChanged so I have to raise an event: <TextBox Text="{Binding SelectedItem.AcknowledgedNote, Mode=TwoWay, UpdateSourceTrigger=Explicit, ElementName=gridReminders}" TextChanged="txtAcknowledgedNote_TextChanged"/> The event to handle this calls BindingExpression.UpdateSource to update the source immediately: private void txtAcknowledgedNote_TextChanged(object sender, TextChangedEventArgs e) { BindingExpression be = txtAcknowledgedNote.GetBindingExpression(TextBox.TextProperty); be.UpdateSource(); } IN other words - typing in the textbox causes CanLoad of the DomainDataSource to become False (because we're editing). This in turn disables the DataGrid (IsEnabled is bound to it) and enables 'Cancel' and 'Save' buttons. However I'm running up against a race condition if I move quickly through rows in the DataGrid (just clicking random rows). The TextChanged presumably is being called on the textbox and confusing the DomainDataSource which then thinks there's been a change. So how should I disable the DataGrid while editing without having the race condition? One obvious solution would be to use KeyDown events to trigger the call to UpdateSource but I always hate having to do that.

• iPhone - User Defaults and UIImages

  - by Staros

  Hello, I've been developing an iPhone app for the last few months. Recently I wanted to up performance and cache a few of the images that are used in the UI. The images are downloaded randomly from the web by the user so I can't add specific images to the project. I'm also already using NSUserDefaults to save other info within the app. So now I'm attempting to save a dictionary of UIImages to my NSUserDefaults object and get... -[UIImage encodeWithCoder:]: unrecognized selector sent to instance I then decided to subclass UIImage with a class named UISaveableImage and implement NSCoding. So now I'm at... @implementation UISaveableImage -(void)encodeWithCoder:(NSCoder *)encoder { [encoder encodeObject:super forKey:@"image"]; } -(id)initWithCoder:(NSCoder *)decoder { if (self=[super init]){ super = [decoder decodeObjectForKey:@"image"]; } return self; } @end which isn't any better than where I started. If I was able to convert an UIImage to NSData I would be good, but all I can find are function like UIImagePNGRepresentation which require me to know what type of image this was. Something that UIImage doesn't allow me to do. Thoughts? I feel like I might have wandered down the wrong path...

• Web user expectations

  - by Ash

  When designing a good Web GUI what expectations can we expect from an end user? I've come up with the following, but I wonder if there are any others which can suggest.. If I click on a hyperlink it will take me to another page/part of this page If I tick/untick a checkbox it might alter the page state (enable/disable elements) If I click on a button I expect it to do something to data. If I click on a button I expect something to happen immediately (either to the current page, or for me to be taken to another page) If I have clicked on a hyperlink and it has taken me to another page, I expect to be able to use the Back button to get back to the previous page in a state similar to that which I left it in If I change something in a form, I can change it back to its previous value if necessary Unless I click on the 'Submit' button nothing should happen to my data. If I bookmark/favourite a page then it should show the same related data each time I visit it If text is underlined and looks like a link, it should be a link and act as one The reasoning behind this question is more a 'UI from hell' one. For example I have come across pages which checking a tickbox next to a record will delete it, straight away, via ajax. To me that just seems wrong, a checkbox is a toggle - something which a delete operation definitely isn't!

• When making a branch in TortoiseSVN, what do "head", "working copy", and "specific" revisions mean?

  - by Asad Butt

  A new user of Tortoise SVN, working over source control. I have a Visual Studio solution which consists of 5 webAppliation projects. I need to take one out and work over it in a branch. When I try to branch it, It is asking me of one of these options head revision in repository specific revision in repository working copy revision Problem 1: What exactly are these ? I am confused with "head revision" and "working copy", as they appear same to me. EDIT: Problem 2: Why cant we branch from Repository GUI itself, (would be head revision) ? Problem 3: Can you list the steps, needed to branch from a directory !

• Catching MediaPlayer Exceptions from WPF MediaElement Control

  - by ScottCate

  I'm playing video in a MediaElement in WPF. It's working 1000's of times, over and over again. Once in a blue moon (like once a week), I get a windows exception (you know the dialog Dr. Watson Crash??) that happens. The MediaElment doesn't expose an error, it just crashes and sits there with an ugly Crash report on the screen. If you "view this report" you can see it is in fact MediaPlayer that has crashed. I know I can disable the crash reports from popping up - but I'm more interested in finding out what's going wrong. I'm not sure how to capture the results of the Dr. Watson capture, but I have the dialog open now if someone has advice on a better way to capture. Here is the opening line of data, that points to my application, then to wmvdecod.dll AppName: ScottApp.exe AppVer: 2.2009.2291.805 AppStamp:4a36c812 ModName: wmvdecod.dll ModVer: 11.0.5721.5145 ModStamp:453711a3 fDebug: 0 Offset: 000cbc88 And from the Win Event Log.

• How to start a major iPhone app update in Xcode

  - by Eric

  I have an app in the iPhone app store and have released several minor updates to it. I want to begin work on some major feature additions and reorganization, but don't want to lose the source code of my most recent version in case everything goes horribly wrong. Should I start a new Xcode project from scratch and copy my existing source in? If I do this will I be able to submit the build from this new project as an update or will Apple complain that the build comes from a different Xcode project? I've seen (but not used) Xcode's "Snapshots" and "Source Control" features - are these what I'm looking for? Any help or direction greatly appreciated.

• Using Subversion in Xcode

  - by Kevin L.

  It seems that all of the initial Google results for "using subversion with xcode" are actually just tutorials for installing and configuring svn and Xcode, as opposed to actually using the two (i.e. interacting with svn via Xcode's GUI). Is anyone aware of a good guide that teaches the tricks and pitfalls of working with svn via Xcode's GUI? Something that bridges the gap between the most excellent Version Control with Subversion book and the Xcode IDE (as in pure Xcode GUI without any terminal command use)? Edit: We all love our terminal commands, and we all love Eclipse but (and I mean this in the nicest possible way) neither is really the point of the question. I’d prefer to use svn via Xcode’s IDE instead of via terminal just as I prefer (well, for this case) to code in Xcode’s IDE instead of using vim and gcc. Apple engineers spent a good bit of time implementing that SCM menu in Xcode; someone has to have seen a usage guide somewhere.

• Organizing a project that uses multiple languages?

  - by calid

  I am currently working on a project that has components in perl, .NET, C/C++, and Java. These components are inter-related, but are not tied to the same release schedule. Due to the very different build/testing environment requirements, lumping them all in to the same /bin /src /lib /etc /tests hierarchy is a bit unwieldy. What are some good organizational hierarchies to use in source control when dealing with a project of this nature? I am currently leaning towards each language having its own branch: repo/project1/perl/main/... repo/project1/.NET/main/... repo/project1/Java/main/... How would your recommended hierarchy change if they DID have a tied release schedule?

• Validating User Input? C#

  - by Alex

  Hi, in an assignment, I have designed a input validation loop in C#, and I would like it to be able to check for the correct input format. I'm not for sure, but I think my designed loop is not checking the type of input, just what char is entered. I know I could use a try-catch block, but shouldn't you only use exceptions for exceptional situations? This is not an exceptional situation, because I expect that the user would enter an incorrect value. Input validation is not part of my assignment, so the loop is in a homework assignment, but is not part of the homework assignment. Question: Is there a way I could redesign this loop so that it checks for valid input type as well? Code: do { Console.Write("Do you wish to enter another complex number?: (Y or N)"); response = char.Parse(Console.ReadLine()); response = char.ToUpper(response); if (response != 'Y' && response != 'N') Console.WriteLine("You must respond Y or N!"); } while (response != 'Y' && response != 'N'); Thanks!!

• Delphi: Moving away from VSS

  - by Mohammed Nasman

  We are team of few Delphi developers who have been using VSS since years (I know it's a pity), but we don't use any of the advanced features of VCS, so it was working fine in many cases (but some times it was driving me crazy :( ). The good thing that we have with VSS that we use third-party plug-ings to integrate VSS with Delphi, which is working great, but now when our projects becomes larger, and we would like to move a way from VSS. I have looked at few other VCS (free and commercial) and found most of them seems be made for Linux guys, and you have to use command line for many admin work(I know I'm windows guy :P). What I'm looking for the new Version control that it should be easy to use and to maintain and Integrated nicely with Delphi IDE (D2007), or at least have a good UI for the Admins an developers.

• Why darcs instead of git?

  - by Ctrl Alt D-1337

  Using pure functional languages can have a lot of benefits over using impure imperatives but low level systems languages will generally allow you to achieve much greater performance especially when they are imperative because it allows you to specify the exact steps in how the cpu should compute the result. If there is ever list of tools where high performance is an absolute must then I would put source version controls systems right at the top of that list and git achieves this very well but performance is not it's only advantage over many other other types of version control systems anyway. The git team are handling the unsafe c code very well and I never worry about my type system or any other features of the language it is written in so why is it that there is a lot of haskell developers that must use darcs when they will only be using the finished product?

• Use web.sitemap to control page access

  - by Jakob Gade

  I was setting up permissions for pages in a ASP.NET website with <location> tags in web.config, something similar to this: <location path="Users.aspx"> <system.web> <authorization> <allow roles="Administrator"/> <deny users="*"/> </authorization> </system.web> </location> However, I also have a web.sitemap which basically contains the same information, i.e. which user roles can see/access which pages. A snippet from my web.sitemap: <?xml version="1.0" encoding="utf-8" ?> <siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" > <siteMapNode title="Home"> ... lots of nodes here ... <siteMapNode url="users.aspx" roles="Administrator" title="users" description="Edit users" /> ... </siteMapNode> </siteMap> Is there some kind of nifty way of using web.sitemap only to configure access? The <location> tags are quite verbose, and I don't like having to duplicate this information.

• How to determine the Window size in IE for a window to be opened from the COM API?

  - by stwissel

  I'm using the IE control embedded in an application. Works as advertised. When a user opens a new browser window I intercept the NewWindow2 event and force it into a new tab. However for a certain class of windows I want to allow a popup. Most notably a few windows legacy applications that use popup windows instead of Ajax for Date or Name pickers. How can I figure out that a window was requested by JavaScript window.open(...) or with a specific size? Thx for helping.

• Anyone use Distributed VCS in a corporate environment?

  - by Eddie Parker

  I'm curious to hear about people's experiences with distributed version control in a corporate environment. Specifically: Was it difficult to gain adoption? Now that it's in place, is it well liked? What 'model' are you using (hub & spoke? Something else?) Allowing you use hub & spoke, are there any discipline problems with pushing to a central server? I'd like to hear if anyone has non-programmers working within this environment, preferably artists and the like to whom VCS can be a bit daunting. Did it work out for them?

• Keyboard input: how to separate keycodes received from user

  - by Iulian Serbanoiu

  Hello, I am writing an application involving user input from the keyboard. For doing it I use this way of reading the input: #include <stdio.h> #include <termios.h> #include <unistd.h> int mygetch( ) { struct termios oldt, newt; int ch; tcgetattr( STDIN_FILENO, &oldt ); newt = oldt; newt.c_lflag &= ~( ICANON | ECHO ); tcsetattr( STDIN_FILENO, TCSANOW, &newt ); ch = getchar(); tcsetattr( STDIN_FILENO, TCSANOW, &oldt ); return ch; } int main(void) { int c; do{ c = mygetch(); printf("%d\n",c); }while(c!='q'); return 0; } Everyting works fine for letters digits,tabs but when hiting DEL, LEFT, CTRL+LEFT, F8 (and others) I receive not one but 3,4,5 or even 6 characters. The question is: Is is possible to make a separation of these characters (to actually know that I only hit one key or key combination). What I would like is to have a function to return a single integer value for any type of input (letter, digit, F1-F12, DEl, PGUP, PGDOWN, CTRL+A, CTRL+ALT+A, ALT+LEFT, etc). Is this possible? I'm interested in an idea to to this, the language doesn't matter much, though I'd prefer perl or c. Thanks, Iulian

• Is there a 3 way merger tool that “understands” common refactoring?

  - by Ian Ringrose

  When a simple refactoring like “rename field” has been done on one branch it can be very hard to merge the changes into the other branches. (Extract method is much harder as the merge tools don’t seem to match the unchanged blocks well) Now in my dreams, I am thinking of a tool that can record (or work out) what well defined refactoring operations have been done on one branch and then “replay” them on the other branch, rather than trying to merge every line the refactoring has affected. see also "Is there an intelligent 3rd merge tool that understands VB.NET" for the other half of my pain! Also has anyone try something like MolhadoRef (blog article about MolhadoRef and Refactoring-aware SCM), This is, in theory, refactoring-aware source control.

• VB.Net: How to fill in a form in a website, then click at a button and download the file using webbr

  I am using a WebBrowser-Control to fill in a webform and then click at a button, this currently results in a standard Download File Dialog (you get these if you download a file using internet explorer), but instead, I have to catch this file and save it automatically with a by me defined name to a specific folder. I am trying to code a little application in vb.net which download the Export-file from my wordpress-blog, and I want to do this completely without user-interaction. Currently everything works, except the downloading of the file. I tried to catch it with the event System.Windows.Controls.WebBrowser.Navigating(ByVal Object, ByVal System.Windows.Navigation.NavigatingCancelEventArgs) but I don't see where to download the file from :( I hope you guys can help me.

• Illustration for code presentation

  - by Lasse V. Karlsen

  I got an odd request, and I fear it will be closed as off-topic. So be it, but it's worth a shot. I'm creating a presentation about dependency injection and inversion of control, and I thought I'd make the point of interchangeable parts that serve a common purpose, but has different implementations, by showing an image I've seen before. Basically the image is of a man or a woman, but the image is split up into four parts: Head Torso uhm... not sure the name of this part, stomach, etc. Legs Possibly a fifth with feet and for each part you can choose among a few variants, creating odd people in the process. ie. a man torso with a woman head. But, I can't find such an image now of course. Does anyone know of such an image and can provide me with an url?
