  • Java application if/case recommendation

    - by Jesse
    I am writing an application for a Java course. I am a complete beginner and am just going off material I have learned from the course and from the web. The application is exhibiting some behavior and I am not sure what is causing it. The application is GUI based and does calculations on user input. For the action listener section, I have a set of If statements such as: "if this button do this if this button do this" All in a row like that. It seems as if the application is running ALL the if statements instead of running the one that corresponds with the button pressed. Would I be better off using a case/switch structure for this sort of thing? I can post my code if necessary, I am new around this site and am not sure if that thing is acceptable.

  • UnauthorizedAccessException when running desktop application from shared folder

    - by Atara
    I created a desktop application using VS 2008. When I run it locally, all works well. I shared my output folder (WITHOUT allowing network users to change my files) and ran my exe from another Vista computer on our intranet. When running the shared exe, I receive "System.UnauthorizedAccessException" when trying to read a file. How can I give permission to allow reading the file? Should I change the code? Should I grant permission to the application\folder on the Vista computer? how? Notes: I do not use ClickOnce. the application should be distributed using xcopy. My application target framework is ".Net Framework 2.0" On the Vista computer, "controlPanel | UninstallOrChangePrograms" it says it has "Microsoft .Net Framework 3.5 SP1" I also tried to map the folder drive, but got the same errors, only now the fileName is "T:\my.ocx" ' ---------------------------------------------------------------------- ' my code: Dim src As String = mcGlobals.cmcFiles.mcGetFileNameOcx() Dim ioStream As New System.IO.FileStream(src, IO.FileMode.Open) ' ---------------------------------------------------------------------- Public Shared Function mcGetFileNameOcx() As String ' ---------------------------------------------------------------------- Dim dirName As String = Application.StartupPath & "\" Dim sFiles() As String = System.IO.Directory.GetFiles(dirName, "*.ocx") Dim i As Integer For i = 0 To UBound(sFiles) Debug.WriteLine(System.IO.Path.GetFullPath(sFiles(i))) ' if found any - return the first: Return System.IO.Path.GetFullPath(sFiles(i)) Next Return "" End Function ' ---------------------------------------------------------------------- ' The Exception I receive: System.UnauthorizedAccessException: Access to the path '\\computerName\sharedFolderName\my.ocx' is denied. at System.IO._Error(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(...) at System.IO.FileStream..ctor(...) at System.IO.FileStream..ctor(String path, FileMode mode) ' ----------------------------------------------------------------------

  • Apache httpd.conf handle multiple domains to run the same application

    - by John Stewart
    So what we are looking for is the ability to do the following: We have an application that can load certain settings based on the domain that it is being accessed from. So if you come from xyz.com we show a different logo and if you come from abc.com we show a different logo. The code is the same, running from same server just detects the domain on the run Now we want to get a dedicated server (any suggestions?) that will enable us to point all the doamins that we want to this server (we change the DNS for the domains to that of our server) and then when the user goes to a certain domain they run the same application. Now as far as I can understand we will need to create a "VirtualHost" in apache to handle this. Can we create a wildcard virtualhost that catches all the domains? I am not an expert with Apache at all. So please forgive if this comes out to be a silly question. Any detailed help would be great. Thanks

  • Maintenance tool for Application Database

    - by Thierry
    Hello ! Does anybody know about a good tool which help maintaining the database of an application ? I'm working on an application which uses a database (Microsoft Sql Server). When a development requires to change something in the database (e.g., structure, data migration...), we create a script (Transact-SQL script) and add it into our revision control tool (subversion - that tool also contains our code). Each script must add a line in a log table to keep a trace of all the scripts that have been ran into a database. In order to build a database for our application, one needs to run all scripts ordered by their creation date. I'm not really happy with this technique notably because it make application migration a bit hard. If we want to install a new version of the application somewhere, e.g., migrate from version 1.3 to 2.1, we must get all the scripts between these two versions. Then run them and ensure that everything is done in a transaction... For sure we could built home-made tools to help but I wonder if some tools already exists to do that kind of job.

  • "Punch card" application

    - by icelava
    Our main-con manager is looking for a "punch card" type of attendance-logging application. We need to take attendance every day, and the most "automatic" method is simply to track when people unlock their Windows desktop screen (not logon, because many simply leave the computer on indefinitely), and report to a remote location/repository, where the administrator will be able to observe which users unlocked their screens each day. Has anybody come across such an application suite? It likely has to be a Windows service so that it operates regardless of who is logged into the system.

  • Application self aware of external database record modifications.

    - by Khou
    How do you make your application aware that a database record was changed or created by an external application rather than the application itself? Do you add a special check sum to the database record or what do you do to stop external changes to the database? (in case it was hacked and the hacker decides to add a new record or change an existing database record)

  • How to make my Java Swing application a Client-Server application?

    - by Jonas
    I have made a Java Swing application. Now I would like to make it a Client-Server application. All clients should be notified when data on the server is changed, so I'm not looking for a Web Service. The Client-Server application will be run on a single LAN, it's a business application. The Server will contain a database, JavaDB. What technology and library is easiest to start with? Should I implement it from scratch using Sockets, or should I use Java RMI, or maybe JMS? Or are there other alternatives that are easier to start with? And is there any server library that I should use? Is Jetty an alternative?

  • Windows Software to Save Arbitrary Application State

    - by ashes999
    VM software does a great job of saving state when you "turn it off," allowing instant and immediate return to that previous state. Is there some application for Windows that allows me to do the same thing, for any arbitrary software? It would allow me to save/restore state, possibly via a shell command or button that it appends to every window. Edit: For clarity, there are two types of apps: those that save their own states, and those that save others' states. Those that save their own state are like Chrome, which on load, reloads the windows you had open last time. That's not what I'm asking about; I'm asking for an app that can save the state of other apps, kind of like VM software does; but for any app. (A trivial test would be load notepad++, type a bunch of stuff, and save-state; on reset-state, you should be able to multi-level undo a lot of what you wrote, as if you never shut down the application.)

  • Java: Convenient way to refactor the application.

    - by Harshal
    Hi, Everyone We have an agile enterprise application built on JSP and Servlet without any design strategy. This application was built in early 2002 considering 1000 users. After 2002, we received lots of requests from the marketing partners. Currently, the application has lots of spaghetti code with lots of Ifs and elses. One class has more than 20,000 lines of code with a huge body of functions without abstraction. Now, we need to support billions of records, what we need to do immediately and gradually? We have to refactor the application? Which framework, we need to use? How the usage of the framework will be helpful to the end users? How to convince the leaders to do the refactoring? How to gain the faster response time as compare to the current system?

How to do this? Thanks...

  • WAS Non-HTTP activation - hooking application startup

    - by Mike Tours
    I'm trying to integrate a netTcpBinding based application that is hosted inside WAS with an IoC container (autofac/spring). Unfortunately, when it starts inside WAS and due to the fact that it is not an Http based application, no events are fired inside the Global application class. I need to catch the application domain startup so that I can configure the IoC container. Is there any way to do this when hosting in WAS? I've seen horrible things involving using static classes inside App_Code folders, but I'd like something somewhat more testable and not quite as dirty.

  • frequent updates of a Tomcat application

    - by Erel Segal Halevi
    I have an application that runs on a Tomcat 7 server on a Windows machine. In its current stage, I have to frequently update and fix it. Whenever I need to update the application, I do all this: Build a new war file; Go to the Windows server, stop the Tomcat service; download the file, put it under webapps; Remove the old application folder under webapps; Remove the old application folder under work/Catalina/localhost (otherwise it keeps the old version cached). Restart the Tomcat service. I am sure there is a way to do all this automatically. What is it?

  • Developing multiple user interfaces for an application

    - by denizkocak
    I want to develop an application which has a graphical user interface that could be developed by using different widget toolkits. For example I want to use Qt, GTK+ or even ncurses as a building block for my user interface for the same application. Moreover users could choose which GUI implementation will be used during the next startup of the application without recompiling it first. I wonder what are possible design strategies and design patterns used in the implementation of this design?
