  • MVC for a desktop application, connection a view/controller pair with another one

    - by lcf
    Hello. I've had mostly experience with "server-side" mvc frameworks very popular in different languages like ASP.NET MVC or Zend Framework for php, Spring for Java etc. Some of them are also possible to use for desktop applications development but I never tried that. I fully understand that design patterns should not limit implementation, they should generally provide ideas and common rules that can be differently implemented. Now I'm playing with one of those mvc frameworks for usual Desktop Applications development (it does not have many tutorials or a decent quickstart) and I have some questions regarding to the mvc paradigm. Here is one of them: What are common ways to link different views / controllers? If I click a button, special controller for that button dispatches the event that is generated, does something with the model, changes view state. But what if I need to interact with another view? Like, when I click on a button, it changes a model, but also I need to open another window or change state of another window (hiding a button on another window let's say...), without changing actually the model. What are common ways here to address this? Should my first controller generate an event for the second controller (or second view)? Or should the second controller be handling events from first view? Some links or examples for any languages/frameworks would be really helpful, thanks!

  • Using opencv in Win32 application for image show

    - by erjik
    Is it possible to output images so that they all will be inside a single window? Before, I used to output data using only opencv functions: cvNamedWindow("Image 1"); cvShowImage("Image 1", img); So I change image, then call: cvShowImage function and so on. But If I want to look at more than one image, then every new image needs its own window to be shown there And what I want is to put every such an output opencv's window inside one big main window. Is it possible to do it? And how?

  • Web Applications Development: Security practices for Application design

    - by Shyam
    Hi, As I am creating more web applications that are targeted for multiple users, I figured out that I have to start thinking about user management and security. At a glance and in my ideal world, all users belong to a group. Permissions and access is thus defined per group (and inherited by the users of that group). Logically, I have my group of administrators, which are identified with a level "7" (integer) clearance. A group of webusers have for example level "1". This in generally all works great for me, but I need some kind of list that I have to keep in mind how I secure my system, and some general practices. I am not looking for a specific environment; I want to learn the why's and how's. An example is privilege escalation. If someone would be able to "push" themselves inside a group with higher privileges, for example the Administration, how can I prevent this, or what measures should I take to have some sort of precaution? I don't like in that case to walk into a caveat. My question is basically: where can I find a good resource, list, policy, book that explains the security of web applications, the why's, the how's and readable if you don't have any experience in the realm of advanced security? I prefer a free resource, as I believe I couldn't be the first one who thought about this. Thank you for your answers, comments and feedback.

  • Application Engineering and Number of Users

    - by Kramii
    Apart from performance concerns, should web-based applications be built differently according to the number of (concurrent) users? If so, what are the main differences for (say) 4, 40, 400 and 4000 users? I'm particularly interested in how logging, error handling, design patterns etc. would be be used according to the number of concurrent users.

  • Preferred menus for C# application.

    - by SeaDrive
    Which of the menu tools do you use for C# windows applications? I began with MainMenu, but when I moved to VS2005, only MenuStrip appeared in the Toolbox, so I assumed it was new and better. However, the merge/replace action seems to require a lot more time and effort, and leave one open to maintenance problems. (Perhaps my real question is "what were they thinking when they created MenuStrip?) Do you drag/drop the menus, or do you write the code? Do you use MainMenu, MenuStrip, or some other alternatives?

  • I cannot make log4net work in my web application :(

    - by vtortola
    Hi, I'm trying to set up log4net but I cannot make it work. I've put this in my Web.config: <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="logfile.log" /> <appendToFile value="true" /> <rollingStyle value="Composite" /> <maxSizeRollBackups value="14" /> <maximumFileSize value="15000KB" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" /> </layout> </appender> <root> <level value="DEBUG" /> <appender-ref ref="RollingFileAppender" /> <appender-ref ref="TraceAppender" /> </root> (StackOverflow is not rendering correctly the code I've pasted, I don't know why) Then, in my code I execute: log4net.Config.XmlConfigurator.Configure(new FileInfo(HttpContext.Current.Server.MapPath("~/Web.config"))); ILog log = LogManager.GetLogger("MainLogger"); if(log.IsDebugEnabled) log.Debug("lalala"); But nothing happen. I check the "log" variable, and contains an LogImpl object, that has all the logging levels enabled. I get no error or configuration warning, I cannot see any file in the root, in the bin or anywhere. What do I have to do to make it work? Cheers.

  • Application demands elevated privs to run on win7 but not vista

    - by Nifle
    I have a simple app that I just tried the installer (Innosetup) on win7(32-bit). After I install it the program icon on the desktop gets that shield on it that notifies the user that the app demands elevated privileges. I thought it was something wrong with the installer and made on using NSIS instead, same problem. Does anyone know why it does that on this computer but not on xp-32, win7-64 bit or Vista 64-bit? If I allow the app to run (Answers yes to the system prompt) it crashes with only the error " has encountered an error. Windows is looking for a solution" and then closes.

    I have been using the NavigationService's Navigate method to navigate to other pages in my WP7 Silverlight app: NavigationService.Navigate(new Uri("/Somepage.xaml?val=dreas", UriKind.Relative)); From Somepage.xaml, I then retrieve the query string parameters as follows: string val; NavigationContext.QueryString.TryGetValue("val", out val); I now need a way to pass a complex object using a similar manner. How can I do this without having to serialize the object every time I need to pass it to a new page?

  • Serving images from Amazon S3 in PHP application

    - by luckytaxi
    So it just occurred to me that once I upload profile pics to S3, I have to figure out a way to keep track of the files. For example, if "susan" uploads 3 profile pics, I need to recall those 3 pictures and display it on her profile page if someone views her page. With that said, would the following work? User uploads picture from form Save file information (filename, user info, etc...) into DB and reference URL from S3 Upload photos to S3 When displaying pictures, I'll query the DB for the info and display the images from S3 accordingly.

  • Grails target folder doesn't appear to be on application's classpath

    - by Kobi
    I have a grails project with some additional java source files under src/java folder. When compiling/running the server, the files under that directory get compiled into the project's target folder, together with all other groovy/grails classes. So far so good. However, when I try to load one of the java source files (from src/java) using reflection (Class.forName to be exact), a ClassNotFoundException gets thrown. What is peculiar about the whole thing is that if I copy that same class from project's target/ folder into the following location (on windows): <myuser>\.grails\1.2.2\projects\<MyProjectName>\resources then no exception gets thrown and the corresponding class is loaded fine. This seems to indicate to me that the integrated grails server only looks at classes within the user's dynamically generated project folder, and not the actual project's target folder. Is my understanding correct? Is there a way to force grails to copy certain classfiles from target/ folder into the resources folder within the user dir? Is there a different way to load the classfiles using reflection? I was looking at using the grailsApplication's classloader but that didn't seem to work either. Any tips would be more than welcome. Thanks a lot in advance!

    A situation that may be quite common in offices is: We communicate with clients over e-mails, exchange documents and spreadsheets with them. Is there any tool which will help me in binding all these outputs. Maybe I may get flamed on this as this is not exactly a programming question. But some inputs may certainly help me. Thanx

  • Finding latest release links on website for C++ Application

    - by Brett Powell
    Basically I have written a game plugin that will allow server admins to update their administration tools from within game rather than having to go download it and install it. The releases are updated regularly, and the beta versions are nightly builds. I am trying to find a way to grab the links from the website, but I cannot think of anyway to do this off of the top of my head. Was hoping someone here might be able to suggest something that would work. http://www.sourcemod.net/snapshots.php Thats the website, basically I am trying to grab the links for the latest stable branch, and latest development branch.

  • are mobile can be used as a devices to develop application

    - by Richa Media and services
    I say that we can work @ mobile using a technique and work with any IDE and use any OS without problem like work on visual studio and use Window 7 How it possible ? 1. We use Mobile like a CPU and Use a monitor to watch code. We use samsung's techniques to display on monitor. it's give signal to monitor wirelessly to display code on monitor 2 We use Wireless keyboard and Mouse (if user like USB then he also use USB keyboard and mouse) 3. We use a component inside of mobile to control all devices like internet , wi-fi bluethoth. by component user easily setup , control and use feature. 4 don't be confused. i am sure to say that we not use mobile to watch code on mobile screen and Mobile 's keyboard because it's too smaller to work so we use Monitor (LCD) to display code and a keyboard to work comfortably and freely. 5. what are you think if you see a developer who work using this way 6. it is not impossible. give me some feedback and suggestion about your thinking on this technologies.
