  • log in as a proxy for a certain user

    - by Samuel
    We have a requirement, wherein the administrative user needs to proxy in as a certain user in an environment where several users (Role: User) are managed by an administrator (Role: Admin). e.g If we have the following users in the database (admin, user1, user2, user3), we would want the admin to proxy as 'user2' and use the system in certain scenarios. Authentication in our web application is based username / password credentials, what mechanisms are available for the admin to proxy as 'user2' when he doesn't have the password for 'user2'. How can the application track such access for audit purposes to mention that 'admin' had proxied for 'user2' and performed certain actions. I am looking for suggestions on supporting this in our j2ee (jboss seam) web application.

  • Can 2 different applications use the same database?

    - by cdonner
    Without additional context, the answer is "no", I think. Here is the context. I want to have a free version and a premium version of the same application. When people buy the application, I want them to be able to "upgrade" without losing their data, i.e. the premium version should install over the free version. I want to use the same code base and just switch a setting to build the premium version. Andoid Market does not let me convert a free app to a paid app, so the trivial option is not available. I am curious if someone has tried this successfully. How does Android Market identify an application - will it think that the premium version is a different app and just install it in parallel?

  • WPF Localization Using LocBaml: Handling Special Symbols

    - by Aryeh
    Hello, I’m dealing with localization of a WPF application (Visual Studio 2010 under Windows 7). I’ve just accomplished the whole process of localization using LocBaml tool, as explained in WPF Globalization and Localization Overview and in related posts. The target language is Italian (it-IT culture). When I run my application in Italian, I have a problem with interpretation of the special symbols of © and ™: they both appear there as a white question sign upon a black diamond-shaped background. The symbols © and ™ appear identically in both English and Italian CSV-files. I tried also the special letters (such as È, à etc.) that are present in Italian but absent in English, and they also are interpreted as the above diamond-shaped question. In Region and Language, I changed the system locale to Italian[Italy], restarted the PC and ran the application again – this helped me in the past to cope with a similar problem in localization of C++ applications under Windows XP, but now it didn’t help, either. Has somebody any idea what is the catch here?

  • Persistence with Vaadin

    - by palto
    Hi I'm trying to learn vaadin. I'm really confused how to do any kind of application development with persistence because if I have a reference to my service layer objects, they get stored in session and I really don't want that. Persistence stuff just isn't serializable. My case is that I have an already made application that uses Spring and I'm creating a new UI for it with Vaadin. I can inject the spring stuff to my Vaadin application but that gets stored in the session. Any tips? By the way how do you post in the Vaadin forums? I can't find a post button or way to register :)

  • Automate GUI tasks?

    - by overtherainbow
    I have a Windows application which is deadware, and it lacks the option of exporting data into a file. The only way to extract data is to copy each line into the clipboard, and paste it in an editor. As a work-around, I'm thinking of recording the action once, and loop through it until it reaches the last line in the application. I know there are quite a few such utilities for Windows, so I'd appreciate it if you could recommend one for this task. Thank you.

  • How UIWindow#addSubview can make memory leak?

    - by Jakub
    Hello, I started to learn using Instrument, but I cannot figure it out. After I start my application, the UI shows up, I do nothing and after few seconds I can see memory leak detected: When I have a look at the second leak I can see the following stack: When I double click on the cell related to my code I can see that it is pointing to the following line of code: [window addSubview:newPostUIViewController.view]; from the method: - (void)applicationDidFinishLaunching:(UIApplication *)application { //creating view controller newPostUIViewController = [[NewPostUIViewController alloc] initWithNibName:@"NewPostView" bundle:nil]; newPostUIViewController.title = @"Post it!"; [window addSubview:newPostUIViewController.view]; // Override point for customization after application launch [window makeKeyAndVisible]; } I wonder, how this can be a reason of a leak? I release newPostUIViewController in the dealloc method of PostItAppDelegate class. Any ideas how this could be explained?

  • Invoke a COM addin option from VBA

    - by rip
    Can I invoke an option on a COM Add-in from a VBA macro in Word or Excel 2007? The COM Add-in was written using VSTO – it adds a custom ribbon tab with a number of options that I want to execute from a VBA macro. I can reference the add-in using Application.COMAddIns("MyAddinName") but I can’t find an option to invoke an option. I’ve also played around with the Application.CommandBars collection, and can see that you can execute an option using CommandBarControl.Execute but I can’t find my command bar in the Application.CommandBars collection. Does anyone know if this is possible?

  • Keep Windows Mobile 6 phone alive in C#

    - by QAH
    Hello! I am making an application for Windows Mobile 6.1 Pocket PC (Touchscreen). I know when a Pocket PC's screen turns off, it goes into a standby mode and applications are pretty much halted in the background. My application can't do that. It needs to keep going. So my question is, how can I keep the phone alive (backlight turned on) until my application is done? An example of this would be video streaming applications such as Youtube. It keeps the phone on while the video is playing. Thanks

  • How-to limit feature functionality

    - by ph0enix
    Are there any standard or "best practice" ways of limiting feature functionality for a particular application? Example: We have a product with a variety of features, and our customers can pick and choose which features they would like to use, and the cost of the product varies based on which features they are actually using. In the past, we have distributed along with our software installer an encrypted license file that contains information about the customer, as well as the collection of features that they have enabled. In code, we read from the license file and enable the functionality according to the license file. This seems to work fine, except there a few disadvantages: Upgrading users with new functionality can be sort of a pain If a particular feature shows up in multiple places throughout the application, a developer might not realize that this feature should be licensed, and forget to check the license file before granting functionality to the user If the license file becomes corrupted, deleted, moved, renamed, etc. the application will not run We're getting ready to roll out a new set of features, and I was just curious what others in the community have done to tackle this problem?

  • How to add a dynamic library to Android?

    - by Malcolm
    I want to add a non-native shared library to Android so every application on the device would be able to use it. I mean using packaged classes just like a core library as if they were present in the application itself. I studied Android source code to figure out a way to add a new path to the application ClassLoader and found out that it is created during startup and there's no way to change the paths later. I can use my own ClassLoader, but all I will get after loading a class will be a reference to a Class object. This way I will be bound to work through reflection mechanism, which is slower than the native execution system. Is there any way to organise a shared library on Android?

  • Sendto shortcuts not working on Vista

    - by tbischel
    I'm trying to customize my sendto shortcut following instructions posted on a How-To Geek article. The problem is that any shortcut I drop into the sendto folder doesn't appear as a shortcut when I right-click-sendto. If I copy the actual application (say, Notepad) into the Sendto folder, it will appear as an option but it will not run. If I create a shortcut by copying the actual application and pasting a shortcut, it doesn't appear. Anyone run into this problem before?

    I've got some application on my Windows XP machine that is generating an HTTP request to aaronsw.com every half hour. We've trapped the packets in wireshark, but wireshark doesn't tell what application generated the packets.

  • error with Security Exception

    - by Alexander
    I am getting the following error on my page: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. The problem is with the following code SmtpClient mailClient = new SmtpClient("smtp.gmail.com", 587); What's weird is that when testing it at my localhost, everything works fine, but when I put it on my 1and1 web host it generates the error above. I contacted their support and here's their answer. We do check the error logs and the operation require a FullTrust environment which currently fall under restriction on .NET Framewor k What should I do?

  • Why wouldn't a flex remoteobject work within a custom component?

    - by Gary
    Please enlighten this flex noob. I have a remoteobject within my main.mxml. I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint. When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence. How could this be? No spelling errors, or anything like that. mxml code: &ltmx:RemoteObject id="myService" destination="remoteService" endpoint="$(Application.application.home}/messagebroker/amf" &gt &lt/mx:RemoteObject%gt function call is just 'myService.getlist();' when I move it to a custom component, I import mx.core.Application; so the compiler doesn't yell

  • Simple, non-blocking way to sleep?

    - by OverTheRainbow
    Hello I googled for this and read some threads here, but I haven't found a simple way to have a VB.Net application sleep for a little while and still keep the application responsive: Imports System.Net Imports System.IO Imports System.Text Imports System.Text.RegularExpressions Imports System.Threading.Thread [...] 'How to keep screen frop freezing? While True ListBox1.Items.Clear() ListBox1.Items.Add("blah") 'Not much difference ListBox1.Refresh() 'Wait 1mn Sleep(60000) End While Is there really no simple, non-blocking solution to have a VB.Net application wait for a few seconds? Thank you.

  • Exec Maven Plugin to Command Line

    - by mistercaste
    I have an application developed in NetBeans/Maven that can be started via command line with: mvn exec:exec "-Dexec.executable=C:\\Java\\jdk1.6.0_33\\bin\\java.exe" "-Dexec.args=-Dlog4j.properties=... -classpath %classpath com.xxx.MyLauncher" -Dexec.classpathScope=runtime -Dexec.workingdir= Now I need to run the application through the standard java command line method, like: java -Dlog4j.properties=... -jar myapp-1.2-SNAPSHOT.jar Unfortunately this does not work in the same manner, as I get the following exception: opencard.core.util.OpenCardPropertyLoadingException: property file not found Questions: What is the difference between launching applications with the Exec-Maven-plugin and the standard java execution on command line? Is there an easy way to convert a Maven execution script to a standard command line? How to run the application succesfully?

  • using MEF with NHibernate and windsor

    - by Fran
    I have an ASP.net MVC application that is using NHibernate under the covers for data access. I'm using the Windsor container to handle injecting ISession references into each controller. This works great, but now I'm looking to expand my application with a pluggable architecture so that I can have a core product and specific add-ons. I found a great article on doing this with MEF. My question is how to make the Windsor container and MEF container, life/work together so that I can achieve this. There was an article (http://codebetter.com/blogs/glenn.block/archive/2009/10/31/should-i-use-mef-with-an-ioc-container.aspx) by Glenn Block that talked about this exact issue. Then end then said that the next article would show you how to do this, but there's no part 2. Has anyone created an application like this using asp.net mvc, mef, nhibernate, castle windsor?
