  • Use multiple inheritance to discriminate useage roles?

    - by Arne
    Hi fellows, it's my flight simulation application again. I am leaving the mere prototyping phase now and start fleshing out the software design now. At least I try.. Each of the aircraft in the simulation have got a flight plan associated to them, the exact nature of which is of no interest for this question. Sufficient to say that the operator way edit the flight plan while the simulation is running. The aircraft model most of the time only needs to read-acess the flight plan object which at first thought calls for simply passing a const reference. But ocassionally the aircraft will need to call AdvanceActiveWayPoint() to indicate a way point has been reached. This will affect the Iterator returned by function ActiveWayPoint(). This implies that the aircraft model indeed needs a non-const reference which in turn would also expose functions like AppendWayPoint() to the aircraft model. I would like to avoid this because I would like to enforce the useage rule described above at compile time. Note that class WayPointIter is equivalent to a STL const iterator, that is the way point can not be mutated by the iterator. class FlightPlan { public: void AppendWayPoint(const WayPointIter& at, WayPoint new_wp); void ReplaceWayPoint(const WayPointIter& ar, WayPoint new_wp); void RemoveWayPoint(WayPointIter at); (...) WayPointIter First() const; WayPointIter Last() const; WayPointIter Active() const; void AdvanceActiveWayPoint() const; (...) }; My idea to overcome the issue is this: define an abstract interface class for each usage role and inherit FlightPlan from both. Each user then only gets passed a reference of the appropriate useage role. class IFlightPlanActiveWayPoint { public: WayPointIter Active() const =0; void AdvanceActiveWayPoint() const =0; }; class IFlightPlanEditable { public: void AppendWayPoint(const WayPointIter& at, WayPoint new_wp); void ReplaceWayPoint(const WayPointIter& ar, WayPoint new_wp); void RemoveWayPoint(WayPointIter at); (...) }; Thus the declaration of FlightPlan would only need to be changed to: class FlightPlan : public IFlightPlanActiveWayPoint, IFlightPlanEditable { (...) }; What do you think? Are there any cavecats I might be missing? Is this design clear or should I come up with somethink different for the sake of clarity? Alternatively I could also define a special ActiveWayPoint class which would contain the function AdvanceActiveWayPoint() but feel that this might be unnecessary. Thanks in advance!

  • Application security issues to consider

    - by user279521
    I am working on the design of a high security application (involving financial information, personal information etc). I need to identify what security measures (application level) will be implemented. The application will involve sending data to and from a database, user login, import export to csv, txt files, and print function. What security features do I need to consider for such an application. (SQL injection for starters) ?

  • Providing unique layout for specific resolution in Android 2.3.3

    - by user1384991
    I need to use specific xml-layouts based on screen resolution, not size. So, the first design is used for resolution <= 480x800, and the second - for resolution = 480x800. How is it done ? update. Possible solution: Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); final int height = display.getHeight(); final int width = display.getWidth();

  • nested updatepanels

    - by Elenor
    When I put nested updatepanels in outer updatepanel, then in code, it shows that outer panel is around the code of all nested panels while design mode shows outer updatepanel is drawn like one row on top of page and nested updatepanels are drawn below that outside of outer updatepanel. Is this normal behavior or there is some problem in my implementation?

  • Getting up to speed on modern architecture

    - by Matt Thrower
    Hi, I don't have any formal qualifications in computer science, rather I taught myself classic ASP back in the days of the dotcom boom and managed to get myself a job and my career developed from there. I was a confident and, I think, pretty good programmer in ASP 3 but as others have observed one of the problems with classic ASP was that it did a very good job of hiding the nitty-gritty of http so you could become quite competent as a programmer on the basis of relatively poor understanding of the technology you were working with. When I changed on to .NET at first I treated it like classic ASP, developing stand-alone applications as individual websites simply because I didn't know any better at the time. I moved jobs at this point and spent the next several years working on a single site whose architecture relied heavily on custom objects: in other words I gained a lot of experience working with .NET as a middle-tier development tool using a quite old-fashioned approach to OO design along the lines of the classic "car" class example that's so often used to teach OO. Breaking down programs into blocks of functionality and basing your classes and methods around that. Although we worked under an Agile approach to manage the work the whole setup was classic client/server stuff. That suited me and I gradually got to grips with .NET and started using it far more in the manner that it should be, and I began to see the power inherent in the technology and precisely why it was so much better than good old ASP 3. In my latest job I have found myself suddenly dropped in at the deep end with two quite young, skilled and very cutting-edge programmers. They've built a site architecture which is modelling along a lot of stuff which is new to me and which, in truth I'm having a lot of trouble understanding. The application is built on a cloud computing model with multi-tenancy and the architecture is all loosely coupled using a lot of interfaces, factories and the like. They use nHibernate a lot too. Shortly after I joined, both these guys left and I'm now supposedly the senior developer on a system whose technology and architecture I don't really understand and I have no-one to ask questions of. Except you, the internet. Frankly I feel like I've been pitched in at the deep end and I'm sinking. I'm not sure if this is because I lack the educational background to understand this stuff, if I'm simply not mathematically minded enough for modern computing (my maths was never great - my approach to design is often to simply debug until it works, then refactor until it looks neat), or whether I've simply been presented with too much of too radical a nature at once. But the only way to find out which it is is to try and learn it. So can anyone suggest some good places to start? Good books, tutorials or blogs? I've found a lot of internet material simply presupposes a level of understanding that I just don't have. Your advice is much appreciated. Help a middle-aged, stuck in the mud developer get enthusastic again! Please!

  • What setup in .Net would most resemble Django

    - by Mingus Rude
    At work we are inte process of starting development on a new web-based product. Before doing so we need to establish what technology stack we are going to use. For this application my preference would have been to use Django but since the development- and management-team is soo heavily rooted with Microsoft the new product will have to be based on Microsoft technologies. So my question is, what setup, with Microsoft technologies, would most resemble a django setup with its MVT-design?

  • prevent IE Mobile from scaling web pages automatically

    - by Adam
    I have not been able to get IE mobile to stop automatically resizing my site design. I am using three stylesheets with media queries to display the site differently on different device screens. I've included the meta tag so it shows the mobile stylesheet on IE mobile but it keeps setting the viewport at 320X480 instead of using the actual size of 480X800. How can I force it to display at the actual screen size instead of scaling for a smaller resolution?

  • Developers portfolios

    - by Alex
    I'm wondering if you have one, or u know any developer/programmer online portofolio. I know many web developers have one (and in many cases very well designed), but not any C++ developer (for example). On the net there are only some good blogs about some programming language, but in many cases these are extremely poor from a design point of view and i'd say very "nerdy".
