  • Structuremap Stackoverflow Exception

    - by Jason Young
    I keep getting a stackoverflow exception when I call "GetInstance" (the last line). All, yes ALL of my types implement ITracker. MultiTracker has a constructor with a single parameter, which is an array of ITracker's. It seems like StructureMap is ignoring the fact that I told it that MultiTracker is the default class I want when requesting the type ITracker. I just can't get it to work. Any thoughts? Container = new Container(x => { //Multitracker takes ITracker[] in its constructor x.ForRequestedType<MultiTracker>().TheDefault.Is.OfConcreteType<MultiTracker>().TheArrayOf<ITracker>().Contains(z => { z.OfConcreteType<ConcreteType1>(); //ConcreteType1 : ITracker z.OfConcreteType<ConcreteType2>(); //ConcreteType2 : ITracker }); x.ForRequestedType<ITracker>().TheDefault.Is.OfConcreteType<MultiTracker>(); }); //Run a test - this explodes Container.GetInstance<ITracker>();

  • How to make a product catalog in C#?

    - by Ervin
    I need to develop a product catalog (about 4000 products) application, which would be given to clients on CD or DVD. The catalog exists in webpage format using PHP and MySQL. IMPORTANT: the application is given to clients who maight have old PC, old System. For minimal requirements I would put Windows XP and Internet Explorer 6 (if needed). I need the following features: 1 search option (after productID AND after keyword) 2 print option (by selecting multiple products) 3 shopping cart (making a list which will be sent to an email address if there is any Internet Connection on the computer) When I was asked to do it I had 2 days to realise a very basic version, so I took the whole website and exported it in HTML pages, and developed an application in C# which contains an embeded browser. So the whole website is now static and put on a CD. Everything fine so far. Now here are the problems: 1. the search option was realized by parsing the html files and reading the productID or looking for keywords inside of them. Put on a CD it was extremely slow (searching in 600MB of html files). FOR THIS I WOULD NEED A SOLUTION WITH A STATIC DATABASE (USING ACCESS OR SOMETHING) TO HAVE INDEXED ROWS, SO THE SEARCH COULD BE A VERY FAST ONE. 2. the printing option was a simply call of the embeded Internet Explorer print functions. Here are two problems: a) user needs IE7 for printing the website scaled (FIT TO PAGE), otherwise the edges of the page are cut down. b) users of this app does not have even the basic PC usage skills, so they can't set the printing settings, so there will appear in header and footer the page numbers and titles. QUESTION: can I set these settings from CSS for printing? 3. couldn't make a a shopping cart as I don't use a database, so I have static websites and content is inside the HTML. QUESTION: WHICH ARE THE BEST SOLUTIONS FOR THE PROBLEMS DESCRIBED ABOVE? PLEASE ANSWER EVEN IF YOUR ANSWER IS FOR ONE QUESTION ONLY. THANKS

  • Open working copy file from eclipse history view

    - by Wolfgang
    The history view of eclipse shows you a list of files changed in a certain revision. When you open the context menu on one of these you have the option 'Open' which opens a view of that file in that revision. How can I open the editor for the selected file, i.e. the file in the version of the working copy, right from the history view? Background is that I want to use the history view to find files that have been changed recently to do code reviewing. People commit via subversion and I use subclipse to connect eclipse to the subversion server. Today, I must use the 'Open resource'/'Open type' function and type the name of the file that I can read from the history view.

  • Design - Where should objects be registered when using Windsor

    - by Fredrik Jansson
    I will have the following components in my application DataAccess DataAccess.Test Business Business.Test Application I was hoping to use Castle Windsor as IoC to glue the layers together but I am bit uncertain about the design of the gluing. My question is who should be responsible for registering the objects into Windsor? I have a couple of ideas; Each layer can register its own objects. To test the BL, the test bench could register mock classes for the DAL. Each layer can register the object of its dependencies, e.g. the business layer registers the components of the data access layer. To test the BL, the test bench would have to unload the "real" DAL object and register the mock objects. The application (or test app) registers all objects of the dependencies. Can someone help me with some ideas and pros/cons with the different paths? Links to example projects utilizing Castle Windsor in this way would be very helpful.

  • Difference between Revert and Update in Mercurial

    - by Edan Maor
    I'm just getting started with Mercurial, and I've come across something which I don't understand. I made changes to several files, and now I want to undo all the changes I made to one of them (i.e. go back to my last commit for one specific file). As far as I can see, the command I want is revert. In the page I linked to, there is the following statement: This operation however does not change the parent revision of the working directory (or revisions in case of an uncommitted merge). To undo an uncomitted merge, you can use "hg update -C -r." which will reset the parents to the first parent. I don't understand the difference between the two (hg revert vs. hg update -C -r). Can anyone enlighten me as to the difference? And in my case, do I really want the revert or the update to go get rid of the changes I made to the file? Thanks

  • Autofac in web applications, where should I store the container for easy access

    - by michielvoo
    I'm still pretty new to using Autofac and one thing I miss in the documentation and examples is how to make it easy to get to the configured container from different places in a web application. I know I can use the Autofac controller factory to automatically resolve constructor injected dependencies for controllers, but how about the other stuff you might need to resolve that is not injected yet. Is there an obvious pattern I am not aware of for this? Thank you!

  • cscript - print output on same line on console?

    - by Guy
    If I have a cscript that outputs lines tothe screen, how do I avoid the "line feed" after each print? Example: for a = 1 to 10 print "." REM (do something) next The expected output should be: .......... Not: . . . . . . . . . . In the past I've used to print the "up arrow character" ASCII code. Can this be done in cscript?

  • Do you continue development in a branch or in the trunk?

    - by Sam McAfee
    Suppose you're developing a software product that has periodic releases. What are the best practices with regard to branching and merging? Slicing off periodic release branches to the public (or whomever your customer is) and then continuing development on the trunk, or considering the trunk the stable version, tagging it as a release periodically, and doing your experimental work in branches. What do folks think is the trunk considered "gold" or considered a "sand box"?

  • IoC, AOP and more

    - by JMSA
    What is an IoC container? What is an IoC/DI framework? Why do we need a framework for IoC/DI? Is there any relationship between IoC/DI and AOP? What is Spring.net/ninject with respect to IoC and AOP?

  • Which single IoC/DI container would you recommend using and why?

    - by Rob G
    I'm asking this question because it's a good way to gauge how the community at large feels about the various containers/frameworks and why. Also, whilst my expertise may lie in .Net development, I am very interested in which frameworks are popular (and why) in other languages. If I feel the need to start digging into Java for instance, then I'd like to hit the ground running with good (comfortable) knowledge that I'm starting in the right direction. Does Ruby even need one with all its magnificent dynamicism? I have my own opinions on the .Net front, and will probably add my own personal favourite in an answer below, but I'm interested in all languages and opinions here. With all that in mind, could you please state only one IoC/DI framework that you use and recommend with the language of choice (Java/Ruby/.Net/Smalltalk etc.) and your reasoning for your choice, and if someone has already answered your particular flavour, then you can just vote it up and add comments to it so that anyone looking for advice in future and see which frameworks are more than likely to work for them once they read your reasoning. I'm hoping that over time, the best ones will bubble up to the top. I realise that this question doesn't have only one correct answer, so I won't be choosing one - the community will decide which framework gets the most votes and why. Of course, if you really feel strongly opposed to a particular brand, you could take the reputation hit and vote it down too, and this question can serve as a true wiki-style entry for research into this field. Remember, only one IoC per answer you write please - if you feel the need to promote two frameworks, then write two answers with your reasoning inside for each choice - then others in the community can agree or disagree with you.

  • How to exit an if clause

    - by Roman Stolper
    What sorts of methods exist for prematurely exiting an if clause? There are times when I'm writing code and want to put a break statement inside of an if clause, only to remember that those can only be used for loops. Lets take the following code as an example: if some_condition: ... if condition_a: # do something # and then exit the outer if block ... if condition_b: # do something # and then exit the outer if block # more code here I can think of one way to do this: assuming the exit cases happen within nested if statements, wrap the remaining code in a big else block. Example: if some_condition: ... if condition_a: # do something # and then exit the outer if block else: ... if condition_b: # do something # and then exit the outer if block else: # more code here The problem with this is that more exit locations mean more nesting/indented code. Alternatively, I could write my code to have the if clauses be as small as possible and not require any exits. Does anyone know of a good/better way to exit an if clause? If there are any associated else-if and else clauses, I figure that exiting would skip over them.

  • [StructureMap] Xml configuration or Configuration through code?

    - by Amith George
    I personally like the option to configure StructureMap from C# code. From what I understand, one of the advantages of DI, is that we can easily swap in a new concrete instance. But, if the configuration is defined in code, then the concrete instances are hardcoded in the dll. So, practically, its as good as having hard coded the dependencies, right? I know, during testing it makes life easier... My point is, wouldnt it be better to use xml configuration instead? you want to plugin a new concrete instance? simply have your installer overwrite the structuremap.config file with the new one. So, what is the preferred way to configure StructureMap? Extra: Am forced to use C# configuration for the time being because I dont know how to pass the connection string to instance. I can write the connectionstring in the config file, but i would like to reuse the connectionstring defined in app.config.

  • how to implement IOC without a global static service (non-service locator solution)?

    - by Michel
    Hi, we want to use Unity for IOC. All i've seen is the implementation that there is one global static service which holds a reference to the Unity container, which registers all interface/class combinations and every class asks that object: give me an implementation for Ithis or IThat. Frequently i see a response that this pattern is not good because it leads to a dependency from ALL classes to this service. But what i don't see often, is: what is the alternative way? Michel EDIT: found out that the global static service is called the service locator, added that to the title.

  • webui for mercurial (hg)

    - by Extreme
    i'm looking for a good webui tool for mercurial. i've found this link Mercurial with WebUI but what i'm looking for is something that has the ability to do check-in and check-out per file like the PVCS. any suggestions? thanks Edit: Here's the link for PVCS. http://en.wikipedia.org/wiki/PVCS It's been around 4 years since I last used PVCS and a lot has probably changed but here's as far as I remember. It has a web application wherein a developer can check out a single file. If this file is checked-out, it will be locked to this developer and no other developer can check it out. Then can download the source but they won't be able to check it in unless the original developer (that checked-out the file) checks it in.

  • How to enforce remote gnupg signing of Mercurial repository only when new tags are created?

    - by Tim Post
    I know how to configure the Mercurial signing extension. The problem that I'm having is that I don't want to sign each individual change set, I only want to sign revisions that introduce new version tags. That's easily accomplished locally, however I can't come up with a way to enforce this on the remote server. I'd like people to continue to be able to push their changes as normal, unless adding a release tag, which should be accompanied by a signature. The end result should be that anyone cloning our repository can easily see a list of signed revisions, which point to a list of signed releases. Hopefully, I've just missed something obvious in hooklib. Has anyone else accomplished this, if so, how?

  • Git - switching between branches in the middle of work

    - by Art
    For various reasons (code review mostly) I need to switch from current development branch to other branches quite often. Currently, I use either 'git stash' to shelve the uncommitted changes, checkout other branch, then switch back and do 'git stash apply' However, sometimes I'd have some newly added files there, which are not tracked. Unfortunately, stashing does not affect them. In this case I'd have to add them to the index and stash. What I am looking here for is a workflow where I'd have to perform a minimal set of actions to switch the branches, preferably avoiding adding of files into the index.

  • Updating Commit Message in Mercurial MQ extension

    - by Jerub
    After using hg qnew and hg qrefresh to create and update a patch that I want to apply to my repository, but the commit message that I wrote when I did hg qnew was not very good, it did not reference the ticket number from trac, and I would like to say something in it about some of the issues that my commit addresses. How do I do something like hg qrewritemycommitmessage. I have examined the docs on the website (starting here: http://mercurial.selenic.com/wiki/MqExtension ) and I have come up blank.

  • Git command to display HEAD commit id?

    - by Andrew Arnott
    What command can I use to print out the commit id of HEAD? This is what I'm doing by hand: $ cat .git/HEAD ref: refs/heads/v3.3 $ cat .git/refs/heads/v3.3 6050732e725c68b83c35c873ff8808dff1c406e1 But I need a script that can reliably pipe the output of some command to a text file such that the text file contains exactly the commit id of HEAD (nothing more or less, and not just a ref). Can anyone help?

  • How do you get notified of your repos' updates?

    - by furtelwart
    I'm working on several repositories at work and would like to be informed, if anything changes in the SVN repositories. I made a small BAT script (yes, BAT is usefull sometimes) that keeps executing an svn log -r BASE:HEAD on my working copy. It shows all submit comments and revision dates. It works really well but it's not comfortable for different repositories. How do you keep track of changes in your repositories? Do you use a small program you made for yourself? Do you use software someone else made? I'm interested in every approach to this problem. I would like to get notifications and several more information about the commit. The IDE integrated functions are good, but work only if I request the information. I don't want to act to get this information. Platform: Windows, Subversion 1.5 and higher.

  • Subversion and project management web based super tool. Like Team Foundation Server but not TFS.

    - by Rob Stevenson-Leggett
    Hi, We're currently looking at an IT upgrade and I'm after recommendations for a tool which can do some or all of the following. SVN management (authz, web viewer, commit log, diff) Create template projects (1 click e.g. create me a microsite with this name in svn and give these people access) Reporting on code churn, time spent on tasks on a per project basis User story management Basically like Team Foundation Server but that integrates with SVN properly (reason for this - we have a wide range of skill sets and not everyone can use a TFS client). Is there a combination of Trac plugins + something that can create trac instances (a la Dreamhost's admin panel) that can acheive this. On a side note, does anyone have any experience of version controlling designery type files - e.g. PSDs, Illustrator files. Any advice at all appreciated. Cheers, Rob
