  • Methodologies for Managing Users and Access?

    - by MadBurn
    This is something I'm having a hard time getting my head around. I think I might be making it more complicated than it is. What I'm trying to do is develop a method to store users in a database with varying levels of access, throughout different applications. I know this has been done before, but I don't know where to find how they did it. Here is an example of what I need to accomplish: UserA - Access to App1, App3, App4 & can add new users to App3, but not 4 or 1. UserB - Access to App2 only with ReadOnly access. UserC - Access to App1 & App4 and is able to access Admin settings of both apps. In the past I've just used user groups. However, I'm reaching a phase where I need a bit more control over each individual user's access to certain parts of the different applications. I wish this were as cut and dry as being able to give a user a role and let each role inherit from the last. Now, this is what I need to accomplish. But, I don't know any methods of doing this. I could easily just design something that works, but I know this has been done and I know this has been studied and I know this problem has been solved by much better minds than my own. This is for a web application and using sql server 2008. I don't need to store passwords (LDAP) and the information I need to store is actually very limited. Basically just username and access.

  • Accessing SQL Server data from iOS apps

    - by RobertChipperfield
    Almost all mobile apps need access to external data to be valuable. With a huge amount of existing business data residing in Microsoft SQL Server databases, and an ever-increasing drive to make more and more available to mobile users, how do you marry the rather separate worlds of Microsoft's SQL Server and Apple's iOS devices? The classic answer: write a web service layer Look at any of the questions on this topic asked in Internet discussion forums, and you'll inevitably see the answer, "just write a web service and use that!". But what does this process gain? For a well-designed database with a solid security model, and business logic in the database, writing a custom web service on top of this just to access some of the data from a different platform seems inefficient and unnecessary. Desktop applications interact with the SQL Server directly - why should mobile apps be any different? The better answer: the iSql SDK Working along the lines of "if you do something more than once, make it shared," we set about coming up with a better solution for the general case. And so the iSql SDK was born: sitting between SQL Server and your iOS apps, it provides the simple API you're used to if you've been developing desktop apps using the Microsoft SQL Native Client. It turns out a web service remained a sensible idea: HTTP is much more suited to the Big Bad Internet than SQL Server's native TDS protocol, removing the need for complex configuration, firewall configuration, and the like. However, rather than writing a web service for every app that needs data access, we made the web service generic, serving only as a proxy between the SQL Server and a client library integrated into the iPhone or iPad app. This client library handles all the network communication, and provides a clean API. OSQL in 25 lines of code As an example of how to use the API, I put together a very simple app that allowed the user to enter one or more SQL statements, and displayed the results in a rather primitively formatted text field. The total amount of Objective-C code responsible for doing the work? About 25 lines. You can see this in action in the demo video. Beta out now - your chance to give us your suggestions! We've released the iSql SDK as a beta on the MobileFoo website: you're welcome to download a copy, have a play in your own apps, and let us know what we've missed using the Feedback button on the site. Software development should be fun and rewarding: no-one wants to spend their time writing boiler-plate code over and over again, so stop writing the same web service code, and start doing exciting things in the new world of mobile data!

  • VCS strategy with TeamCity and CI

    - by Luke Puplett
    I'm planning a strategy which seeks to allow automated deployment of a website codebase into QA and production on check-in. We're using the fabulous TeamCity. We want to control release to live production; i.e. not have every check-in on Trunk go live. So my plan is to use Trunk as QA. Committing to Trunk triggers deployment to QA. I will then have a Production branch which also triggers deployment on commit, to the live site. The idea is simply that Trunk represents the mainline codebase but it hasn't gone live yet. We can branch features and do daily pulls from Trunk into those feature branches as per normal and merge/re-integrate into Trunk when we're happy for it to go to QA. When the BAs give the nod, we then smash a bottle of champagne and merge Trunk to Production and out she goes. I've never seen it done like this. Other greenfield CI strategies involve hiding features and code from production via config - this codebase can't cope with that - or just having CI on QA and taking cuts and manually pushing to live. Does my plan sound alright?

  • Using Microsoft&apos;s Chart Controls In An ASP.NET Application: Serializing Chart Data

    In most usage scenarios, the data displayed in a Microsoft Chart control comes from some dynamic source, such as from a database query. The appearance of the chart can be modified dynamically, as well; past installments in this article series showed how to programmatically customize the axes, labels, and other appearance-related settings. However, it is possible to statically define the chart's data and appearance strictly through the control's declarative markup. One of the demos examined in the <a href="http://www.4guysfromrolla.com/articles/072209-1.aspx">Getting Started</a> article rendered a column chart with seven columns whose labels and values were defined statically in the <code>&lt;asp:Series&gt;</code> tag's

  • What does SVN do better than git?

    - by doug
    No question that the majority of debates over programmer tools distill to either personal choice (by the user) or design emphasis, i.e., optimizing design according to particular uses cases (by the tool builder). Text Editors are probably the most prominent example--a coder who works on a Windows at work and codes in Haskell on the Mac at home, values cross-platform and compiler integration and so chooses Emacs over Textmate, etc. It's less common that a newly introduced technology is genuinely, demonstrably superior to the extant options. I wonder if this is in fact the case with version-control systems, in particular, centralized VCS (CVS, SVN) versus distributed VCS (git, hg)? I used SVN for about five years, and SVN is currently used where I work. A little less than three years ago, I switched to git (and gitHub) for all of my personal projects. I can think of a number of advantages of git over subversion (and which for the most part abstract to advantages of distributed over centralized VCS), but I cannot think of one contra example--some task (that's relevant and arises in a programmers usual workflow) that subversion does better than git. The only conclusion I have drawn from this is that I don't have any data--not that git is better, etc. My guess is that such counter-examples exist, hence this question.

  • How to keep the trunk stable when tests take a long time?

    - by Oak
    We have three sets of test suites: A "small" suite, taking only a couple of hours to run A "medium" suite that takes multiple hours, usually ran every night (nightly) A "large" suite that takes a week+ to run We also have a bunch of shorter test suites, but I'm not focusing on them here. The current methodology is to run the small suite before each commit to the trunk. Then, the medium suite runs every night, and if in the morning it turned out it failed, we try to isolate which of yesterday's commits was to blame, rollback that commit and retry the tests. A similar process, only at a weekly instead of nightly frequency, is done for the large suite. Unfortunately, the medium suite does fail pretty frequently. That means that the trunk is often unstable, which is extremely annoying when you want to make modifications and test them. It's annoying because when I check out from the trunk, I cannot know for certain it's stable, and if a test fails I cannot know for certain if it's my fault or not. My question is, is there some known methodology for handling these kinds of situations in a way which will leave the trunk always in top shape? e.g. "commit into a special precommit branch which will then periodically update the trunk every time the nightly passes". And does it matter if it's a centralized source control system like SVN or a distributed one like git? By the way I am a junior developer with a limited ability to change things, I'm just trying to understand if there's a way to handle this pain I am experiencing.

  • Trac/SVN to DVCS Migration

    - by quanticle
    The project I'm currently working on is using Trac, with SVN integration. It's worked great until now. Now, however, we've taken on some additional developers and we're running into issues with branching and merging. Because of this, I think a move to a distributed version control system is in order. The problem is that Trac is very closely integrated with the SVN repository. We have tight integration between the tickets and the revision numbers of code changes corresponding to those tickets. In addition we have a support wiki that has a lot of data that helps the tech. support team. Is there a way we can migrate to git or mercurial without losing the benefits of Trac? I've looked at the git plugin for Trac, and I'm unsure of how well it works. Has anyone here used it with a project that's been migrated from SVN? EDIT: I should note that the most important priority for us is maintaining the links between Trac tickets and the corresponding changesets in SVN. That's a tool that we use every day, and it provides an easy way to jump to code changes when reviewing tickets. Wiki migration would be nice to have, but if it's not possible, we can continue to run the old system whilst we write some kind of a one-off script to migrate the content.

  • Are there any good examples of open source C# projects with a large number of refactorings?

    - by Arjen Kruithof
    I'm doing research into software evolution and C#/.NET, specifically on identifying refactorings from changesets, so I'm looking for a suitable (XP-like) project that may serve as a test subject for extracting refactorings from version control history. Which open source C# projects have undergone large (number of) refactorings? Criteria A suitable project has its change history publicly available, has compilable code at most commits and at least several refactorings applied in the past. It does not have to be well-known, and the code quality or number of bugs is irrelevant. Preferably the code is in a Git or SVN repository. The result of this research will be a tool that automatically creates informative, concise comments for a changeset. This should improve on the common development practice of just not leaving any comments at all. EDIT: As Peter argues, ideally all commit comments would be teleological (goal-oriented). Practically, if a comment is made at all it is often descriptive, merely a summary of the changes. Sadly we're a long way from automatically inferring developer intentions!

  • Robust way to keep records of software releases?

    - by japreiss
    We release a number of small plug-ins that go along with our software. Each plug-in allows our software to talk to a single manufactuer's hardware. I would like to devise a system for keeping track of plug-in releases. Example info that should be stored: Hardware manufacturer name 32-bit? 64-bit? both? What modes of operation does the hardware support? What versions of the manufacturer's driver have been tested with the plugin? Desirable properties of the system: Able to synchronize with version control software Stores data in human-readable text file (also good for differ tool) Free visual, spreadsheet-like editor available Able to do simple analysis like "What is the oldest plug-in?" I've got to imagine that someone else has tackled this problem already. Right now my best guess is XML/JSON with a visual editor, but I have been disappointed in the editors I've tried so far. I'd like to get input from some more experienced developers. Thanks!

  • How does process of updating code with Continous Integration work?

    - by BleakCabalist
    I want to draw a model of process of updating the source code with the use of Continous Integration. The main issue is I don't really understand how it works when there are several programmers working on various aspects of the code at the same time. I can't visualize it in my mind. Here's what I know but I might be wrong: New code is sent to repository. Continous Integration server asks Version Control System if there is a new code in repository. If there is than CIS executes tests on the code. If tests show there are problems than CIS orders VCS to revert back to working wersion of the code and communicates it to programmer. If tests are passed positively it compiles the repository code and makes new build of a game? New build is made not after ever single change, but at the end of the day I believe? Are my assumptions above correct? If yes, does it also work when there are several programmers updating repository at once? Is this enough to draw a model of the process in your opinions or did I miss something? Also, what software would I need for above process? Can you guys give examples for CIS software and VCS software and whatever else I need? Does CIS software perform code tests or do I need another tool for that and integrate it with CIS? Is there a repository software?

  • Flex: force display of control's errorTip (error toolTip) on validation failure

    - by Jeremy Mitchell
    When a Validator (i.e. StringValidator, NumberValidator, etc) dispatches an invalid event due to validation failure, the errorString property of the source control (i.e. TextInput) is set to a non-empty string which creates a red border around the control and shows an toolTip (errorTip) ONLY when the mouse hovers over the control. Question: Can you force immediate display of the toolTip (errorTip) rather than waiting for the user to hover over the control? If so, how?

  • JavaScript: Alternative to JQuery's (dual) Slider control?

    - by GregJohn
    I am using the JQuery Slider control for use as a double sided slider (dual slider). It's a great UI control but I'm looking for an alternative that isn't so "fat". Right now, just for me to use the Slider control, I have to include: JQuery core JQuery UI core JQuery Slider plugin When I both minimize using Google's awesome Closure (minimizer) and GZIP the JavaScript, I'm still at around 29kb. Question: Do any comparable (dual) Slider control exist that isn't such a large download?

  • Using the string resources of ASP.NET membership provider in a custom control

    - by Dirk
    I have the request to build a custom control for ASP.NET membership. The control is somewhat special. So I can’t inherit from a built-in control. Is there an elegant way to access the string resources of ASP.NET membership provider to use them in custom controls? Creating for example CreateUserWizard, extracting the resources and throwing away the control seems a little bit rustic to me.

  • Masked Time control in WPF

    - by Ashish Ashu
    We are in need of a control in which we can show the elapsed time in "Hour:Min:Sec" format. This control should have a spin control attached with it. Whenever we spin the spin window, it should increment the selected option ( Either hour, or min , or sec). Also the Hour may have values between 0 to 99 , Min many have values between 0 to 59 and Sec may have values between 0 to 59. Is anybody know this type of control in WPF?

  • UpdateProgress with UpdatePanel not showing up in User control when page is loading

    - by Carter
    Is this typical behavior of the UpdateProgress for an ASP.Net UpdatePanel? I have an update panel with the UpdateProgress control inside of a user control window on a page. If I then make the page in the background do some loading and click a button in the user control update panel the UpdateProgress does not show up at all. It's like the UpdatePanels refresh request is not even registered until after the actual page is done doing it's business. It's worth noting that it will show up if nothing is happening in the background. The functionality I want is what you would expect. I want to loader to show up if it has to wait for anything to get it's refresh done when after the button is clicked. I know I can get this functionality if I just use jquery ajax with a static web method, but you can't have static web methods inside of a user control. I could have it in the page but it really doesn't belong there. A full-blown wcf wouldn't really be worth it in this case either. I'm trying to compromise with an UpdatePanel but these things always seem to cause me some kind of trouble. Maybe this is just the way it works? Edit:So I'll clarify a bit what I'm doing. What's happening is I have a page and all it has on it are some tools on the side and a big map. When the page initially loads it takes some time to load the map. Now if while it's loading I open up the tool (a user control) that has the update panel in question in it and click the button on this user control that should refresh the update panel with new data and show the loading sign (in the updateprogress) then the UpdateProgress loading image does not show up. However, the code run by the button click does run after the page is done loading (as expected) and The UpdateProgress will show up if nothing on the page containing the user control is loading. I just want the loader to show up while the page is loading. I thought my problem was that perhaps the map loading is in an update panel and my UpdateProgress was only being associated with the update panel for the user control's update panel. Hence, I would get no loading icon when the map was loading. This is not the case though.

  • Can a custom WPF control implement the IsDefault property

    - by jpierson
    I have a custom button control that does not derive from Button. Is it possible for me to implement the equivalent of IsDefault so that the command associated with my control will be invoked. I was hoping that this was an attached property that I could add to any control but as far as I can tell it doesn't seem to be. Am I out of luck if my control does not derive from Button or is there at least a reasonable workaround?
