  • How to design console application with good seperation of UI from Logic

    - by JavaSa
    Is it considered an overkill for console application to be design like MVC , MVP or N tier architecture? If not which is more common and if you can link me to simple example of it. I want to implement a tic tac toe game in console application. I have a solution which hold two projects: TicTacToeBusinessLogic (Class library project) and TicTacToeConsoleApplication (Console application project) to represent the view logic. In the TicTacToeConsoleApplication I've Program.cs class which holds the main entry point (public static void Main). Now I face a problem. I want the game to handle its own game flow so I can: Create new GameManager class (from BL) but this causing the view to directly know the BL part. So I'm a little confused how to write it in an acceptable way. Should I use delegates? Please show me a simple example.

  • Looking software for making an animated cartoon to present a new application/scenario idea [closed]

    - by Skarab
    I have an idea for an application (+usage scenario) and I would like to create an animated cartoon that shows a use case for this application and its novelty. My company is a rather big so I am looking for an interesting way to get people know my idea to get feedback/get a green light to further develop it. Therefore I am looking for an application (free or commercial) that I could use to realize such an animated cartoon. I have posted this quesion before on stackoverflow, but I think this might be a better community to ask such a question.

  • Revamp application

    - by Rauf
    I am a software developer having an experience of 3 yrs. I want to play with latest technologies always. But this is not practical. Because say, I developed a web application in .Net 3.5, now its 30% done. After the release of .Net 4.0, my mind is always goes with .Net 4.0. I think like this, lot of features are in new version, so why shouln't I implement those versions in my application. When I worked with IT companies, most of them code with very old versions, some body use VB.NET, C, even Classic ASP. So what might be the points should I consider if I revamp an application?

  • Application lens as default

    - by user24484
    I want to open the Application lens in the Unity Dash as the default lens, since I much more open a programm then searching for a wikipedia article, the weather or anything else the home lens offers. Here How do I show the Applications Lens By Default? and here What are Unity's keyboard and mouse shortcuts? are the same questions, but the suggested answers don't work anymore on Trusty. I know that I can open the application lens with Super + A but I just would like to press Super to open it. An alternative would be to only get online suggestions whe partikular asked for them, but even though I just select the application scope in the filter section I get some useles online results. Btw. I don't want to open the online search results in generall, since I just reactivated them to try it out.

  • Subscribe/Publish Model in Web-based Application (c#) - Best Practices for Event Handlers

    - by KingOfHypocrites
    I was recently exposed to a desktop application that uses an publish/subscribe model to handle commands, events, etc. I can't seem to find any good examples of using this in a web application, so I wonder if I am off base in trying to use this for web based development (on the server side)? I'm using asp.net c#. My main question in regards to the design is: When using a publish/subscribe model, is it better to have generic commands/events that pass no parameters and then have the subscribers look at static context objects that contain the data relevant to the event? Or is it better to create custom arguments for every event that contain data related to the event? The whole concept of a global container seems so convenient but at the same time seems to break encapsulation. Any thoughts or best practices from anyone who has implemented this type of model in a web based application? Even suggestions on this model out of the scope of my question are appreciated.

  • google maps based desktop application

    - by dramaticlook
    I want to build a desktop application which has google maps embedded to it. This app should have a thread to read coordinate data online a usb microphone to use. This application will move the google map markers to their new locations based on the data retrieved from online connections on each refresh. As far as I know gmaps has a javascript API so the first idea in my mind was to embed this mapview into a java applet. So the application will run on a browser. Im not sure if this will work. Do you guys have any idea about this or any other advices you might have? Thanks in advance!!!

    - by Adam
    new ubuntu user. after boot (boot is quite fast), opening applications such as firefox, libra, system settings, takes close to 10 seconds to open. after the application is loaded in RAM, the application opens fine. the system feels snappy, quick. when i have two FIREFOX open, unity is snappy in showing me the two windows side by side. but upon bootup, loading the application takes 10 seconds. there is not much hdd activity. fresh install. its the same for system settings and browsing system settings. when system settings is opened for the first time (10 second), and i click for example Color, it will take quite long to open the color settings. hardware: i3 4gb ram radeon 5770 250gb sata gigabyte h55m motherboard i am using ubuntu straight out of the box, no propriety drivers. 64 bit. i have reinstalled OS, and still the same.

  • Starting application in same window with XFCE4 Terminal and i3

    - by Luke
    Since recently I'm enjoying the i3 tiled window manager. I did install the XFCE4 Terminal since it gives greater control over my terminal look and feel however but I have noticed an issue with starting GUI based applications. When I execute a GUI based application I want it take over the current terminal window. To do this I use exec, as in: exec eclipse This will open a new window and leave the terminal I started the application in open as well. In normal circumstances this is not much of a problem since I can easily do an Alt-W on the GUI app's window. However, for some applications, like a file manager, it is necessary to open in the same window. How can I make GUI application open in the same window rather than opening a new one?

  • Distributing a very simple application

    - by vanna
    I have a very simple working console application written in C++ linked with a light static library. It is just for testing purposes. Now that the coding part is done, I would like to know the process of actually distributing the program. I wrote a very basic CMakeLists.txt that create makefiles or VS projects to build the sources. I also have a program that calls the static library in order to make some google tests. To me, the distribution of this application goes like this : to developpers : the src directory with the CMakeLists.txt file (multi-platform distribution) with a README.txt and an INSTALL.txt to users : the executable and a README.txt on my git repo : everything mentionned above plus the sources for testing and the gtest external lib A this point : considering the complexity of my application, am I doing it right ? Is there any reference that would formalize this distribution process so I can get better and go further ? Say I would like to add dynamic libraries that can be updated, external libraries like boost : how should I package this to distribute it in a professionnal way ?

  • How can I designed multi-threaded application for larger user base

    - by rokonoid
    Here's my scenario, I need to develop a scalable application. My user base may be over 100K, every user has 10 or more small tasks. Tasks check every minute with a third party application through web services, retrieving data which is written in the database, then the data is forwarded to it's original destination. So here's the processing of a small task: while(true){ Boolean isNewInformationAvailable = checkWhetherInformationIsAvailableOrNot(); If(isNewInformationAvailable ==true){ fetchTheData(); writeToDatabase(); findTheDestination(); deliverTheData(); isAvailable =false; } } Here is the question: as the application is large, how should I approach designing this. I'm going to use Java to write it. Should I use concurrency, and how would you manage the concurrency?

  • How to fix “Error: This solution contains no resources scoped for a Web application and cannot be deployed to a particular Web application.”

    - by ybbest
    Problem: When I try to deploy my custom wsp solution to a specific web application, I got the error below: This solution contains no resources scoped for a Web application and cannot be deployed to a particular Web application. Analysis: The error message itself explains why you cannot deploy the solution to a web application. However if you do not like to deploy the solution to all the web applications and only like to deploy your solution to a specific application , you need to change the solution settings Assembly Deployment Target from GlobalAssemblyCache to WebApplication. From: TO: Solution: After you change the Assembly Deployment Target and run the script again, you will have the solution deployed successfully.

  • Missing UAC shield overlay on desktop shortcut icon when created by msi created from VS 2008

    - by Alain Hogue
    I created a setup program to deploy my VBNet program using Visual Studio 2008. Inside this setup program I created a shortcut to the "primary output" to be installed on the user desktop. Now, everything is working correctly. The program is installed under "C:\Program Files" and the shortcut is created on the desktop. Also, when I use this shortcut I am prompted by UAC to autorize running this program as administrator. So far, so good... But! My desktop icon does not have the UAC shield overlay even if the program is compiled with the manifest stating that it must run as administrator. Also, if I manually create a new shortcut on the desktop to the same executable after the installation, this new shortcut WILL have the shield overlay! I have tried to reboot and delete the iconCache.db file but it did not work. So my question is: How can I have my desktop shortcut appear WITH the UAC shield overlay when installed initially. Thanks!

  • Create Silverlight application in Blend then migrate to Visual Studio

    - by Mohit Deshpande
    I want to make a Silverlight application in Expression Blend because of the rich UI and navigation of Blend. But I want to store the Silverlight application in an ASP.NET MVC web project. When I try to make a new Silverlight application, the default web application is an ASP.NET Web application (or web site, if I'm wrong). Can I make a single Silverlight application (no web project) then import in an ASP.NET MVC application? How can I do this?

  • WPF Application Slow Unresponsive when demonstrating using remote sharing software

    - by Kev
    After spending 14 hours on this I think its time to share my woes and see if anyone has experienced this issue before. Ill describe the issue and tests I have done to rule out certain things. Ok so I have a WPF application which loads in data from an SQL database. I am using DevExpress Components for datagrids, ribbons etc.. and FluentNhibernate to provide a session for database operations. I am also using log4net to log events to a textfile. Using the application on my laptop with SQL Express 2008 works fine.. the application starts up, retrieves 1000 records and I can tab through the controls on the ribbon. Now, I decided to demo the application to a third party and used remote login/sharing software online to share my desktop with the other person so as I could load the application on my laptop and they could view me using the application. Now, the application takes approx 45 seconds to load... 30 seconds with a blank database where as, when im not sharing out my screen using the online software the application loads in about 7-10 seconds. As well as that, even using the controls in the application during the demo were very sticky, slow and unresponsive. During the sharing session though however I was able to use other applications without any problems.. everything else worked fine. But I cannot understand how my application works ok under normal conditions , even browsing the net at the same time etc... BUT totally fails to perform correctly when I am sharing a session with another user... the CPU usage shot up to 100% too at times when the application was trying to start up... Please see below a list of 3rd party dlls I am using as references in my project. DevExpress dlls FluidKit PixelLab.WPF PixelLab.Common Galasoft WPF Kit FluentNHibernate NHibernate Nhibernate.ByteCode.Castle Skype4ComLib TXTEXTControl log4net LinqKit All of these DLLs are in the output folder with the application dlls created from the class assemblys in the project. So when installed via an installer on a machine the dlls will be in the same application folder as the application file itself. Many thanks

  • How to Setup Java Application

    - by Ari
    I have a 'desktop' java application which is in the form of a jar file. How can I: Store this application on a single server. Grant access via Terminal Services to a specific OU to run this application from the central location. Disallow the copying or moving of the application (jar file) to any other location. Allow the saving/copying/moving of the output of the application on an authorized user's local drive. Thanks.

  • Problems compiling with Quickly

    - by espectalll123
    Welcome to another of my questions about compiling! :P So, after days of stress trying to compile my app, first manually, after porting the project to Quickly, I decided to create the project from scratch using this time Quickly. Now I've finished the app, it works great using quickly run and I haven't added any new file, just removed, replaced or modified. But it can't be compiled using quickly package --verbose --extras... why, if there doesn't seems to be errors related with my project? The fail happens because python-mkdebian doesn't haves enough parameters to work. The terminal output (in Spanish): running install_egg_info Writing /tmp/tmpsT6Pms/virtuam-0.1.egg-info WARNING: the following files are not recognized by DistUtilsExtra.auto: help/C/figures/icon.png help/C/index.page help/C/preferences.page help/C/topic1.page virtuam.desktop.in Traceback (most recent call last): File "/usr/bin/python-mkdebian", line 368, in <module> egg = get_egg_info() File "/usr/bin/python-mkdebian", line 35, in get_egg_info k, v = l.strip().split(': ', 1) ValueError: need more than 1 value to unpack Ha ocurrido un error al crear el paquete Debian ERROR: no se puede crear o actualizar paquete ubuntu Error: la orden package ha fallado Cancelando

  • Is there any way to facilitate switching windows in Ubuntu?

    - by Ivan
    I'm just a student who received my laptop from my uncle, who's a coder, so I'm still getting used to working with ubuntu. I recently upgraded ubuntu from an earlier version, and everything seems to be pretty great. The only thing is that when I open a program, or file, or whatever, it takes up the whole screen. I can only close it by going to the far top left of my screen, or by ctrl+W. Anyways, I find it really hard to switch between programs. For example I really like to have my windows that are open to be accessible by clicking on their icon at the bottom of the screen... Great when writing or researching. Anyways, I really just want to find an easier way to switch windows. Also, I used to love the way I could cube-rotate my screen, and just drag files from one desktop to another, with compiz. Now, its sort of like flipping a coin when I switch windows, is there any way to get my desktop cube back? And yes, I have enabled all the old settings I used to use with compiz. Sorry if what I'm asking is very basic, I know how to use a computer, I'm just not really familiar with the interface! Any help is greatly appreciated.

  • How Visual WebGui helps ASP.NET Cloud-based apps

    - by Visual WebGui
    Everyone is talking about Cloud computing and moving to the cloud (public or private), but very few have actually done it so far. The reason is that the process of migrating existing applications to the cloud is a lot more complicated than one might think which is exactly where the Visual WebGui technology comes in for a rescue. In the past year the Visual WebGui R&D Team have been intensively working on a tool-based solution that gives Microsoft application developers and enterprises a simpler...(read more)

  • Cross platform application revolution

    - by anirudha
    Every developer know that if they make a windows application that they work only on windows. that’s a small pity thing we all know. this is a lose point for windows application who make developer thing small means only for windows and other only for mac. this is a big point behind success of web because who purchase a operating system if they want to use a application on other platform. why they purchase when they can’t try them. that’s a thing better in Web means IE 6 no problem IE 6 to IE 8 chrome to chrome 8 Firefox to Firefox 3.6.13 even that’s beta no problem the good website is shown as same as other browser. some minor difference may be can see. the cross platform application development thinking is much big then making a application who is only for some audience. the difference between audience make by OS what they use Windows or mac. if they use mac they can’t use this they use windows they can’t use this. Web for Everyone starting from a children to grandfather. male and female Everyone can use internet.no worrying what you have even you have Windows or mac , any browser even as silly IE 6. the cross platform have a good thing that “People”. everyone can use them without a problem that. just like some time problem come in windows that “some component is missing click here to get them” , you can’t use this [apps] software because you have windows sp1 , sp2  sp3. you need to install this first before this. this stupidity mainly comes in Microsoft software. in last year i found a issue on WPI that they force user to install another software when they get them from WPI. ex:- you need to install Visual studio 2008 before installing Visual studio 2010 express. are anyone tell me why user get old version 2008 when they get latest and express version. i never try again their to check the issue is solved or not. a another thing is you can’t get IE 9 on windows XP version. in that’case don’t thing and worrying about them because Firefox and Chrome is much better. the stupidity from Microsoft is too much. they never told you about Firebug even sometime they discuss about damage tool in IE they called them developer tool because they are Microsoft and they only thing how they can market their products. you need to install many thing without any reason such as many SQL server component even you use other RDBMS. you can’t say no to them because you need a tool and tool require a useless component called SQL server. i never found any software force me to install this for this and this for this before install me. that’s another good thing in WEB that no thing require i means you not need to install dotnet framework 4 before enjoy facebook or twitter. may be you found out that Microsoft's fail project Window planet force you to get silverlight before going their. i never hear about them. some month ago my friend talked to me about them i found nothing better their. Wha’t user do when facebook force user to install silverlight or adobe flash or may be Microsoft dotnet framework 4. if you not install them facebook tell  you bye bye tata ! never come here before installing Microsoft dotnet framework 4. the door is open for you after installing them not before. the story is same as “ tell me sorry before coming in home” as mother says to their child when they do something wrong. the web never force you to do something for them. sometime they allow you to use other website account their that’s very fast login for you. because they know the importance of your time.

  • Part 15: Fail a build based on the exit code of a console application

    In the series the following parts have been published Part 1: Introduction Part 2: Add arguments and variables Part 3: Use more complex arguments Part 4: Create your own activity Part 5: Increase AssemblyVersion Part 6: Use custom type for an argument Part 7: How is the custom assembly found Part 8: Send information to the build log Part 9: Impersonate activities (run under other credentials) Part 10: Include Version Number in the Build Number Part 11: Speed up opening my build process template Part 12: How to debug my custom activities Part 13: Get control over the Build Output Part 14: Execute a PowerShell script Part 15: Fail a build based on the exit code of a console application When you have a Console Application or a batch file that has errors, the exitcode is set to another value then 0. You would expect that the build would see this and report an error. This is not true however. First we setup the scenario. Add a ConsoleApplication project to your solution you are building. In the Main function set the ExitCode to 1     class Program    {        static void Main(string[] args)        {            Console.WriteLine("This is an error in the script.");            Environment.ExitCode = 1;        }    } Checkin the code. You can choose to include this Console Application in the build or you can decide to add the exe to source control Now modify the Build Process Template CustomTemplate.xaml Add an argument ErrornousScript Scroll down beneath the TryCatch activity called “Try Compile, Test, and Associate Changesets and Work Items” Add an Sequence activity to the template In the Sequence, add a ConvertWorkspaceItem and an InvokeProcess activity (see Part 14: Execute a PowerShell script  for more detailed steps) In the FileName property of the InvokeProcess use the ErrornousScript so the ConsoleApplication will be called. Modify the build definition and make sure that the ErrornousScript is executing the exe that is setting the ExitCode to 1. You have now setup a build definition that will execute the errornous Console Application. When you run it, you will see that the build succeeds. This is not what you want! To solve this, you can make use of the Result property on the InvokeProcess activity. So lets change our Build Process Template. Add the new variables (scoped to the sequence where you run the Console Application) called ExitCode (type = Int32) and ErrorMessage Click on the InvokeProcess activity and change the Result property to ExitCode In the Handle Standard Output of the InvokeProcess add a Sequence activity In the Sequence activity, add an Assign primitive. Set the following properties: To = ErrorMessage Value = If(Not String.IsNullOrEmpty(ErrorMessage), Environment.NewLine + ErrorMessage, "") + stdOutput And add the default BuildMessage to the sequence that outputs the stdOutput Add beneath the InvokeProcess activity and If activity with the condition ExitCode <> 0 In the Then section add a Throw activity and set the Exception property to New Exception(ErrorMessage) The complete workflow looks now like When you now check in the Build Process Template and run the build, you get the following result And that is exactly what we want.   You can download the full solution at BuildProcess.zip. It will include the sources of every part and will continue to evolve.
