• CMS (Web Application OR Windows Application)

  - by Raha

  I am a little bit puzzled about something. I am creating a ASP.NET MVC eCommerce application and currently I have written all the back end in ASP.NET MVC. I was thinking if its better to write all the management in WPF instead of HTML, as its probably even less prone to be exploited by hackers. I am a Windows user so I am not really bothered about using Linux/Mac at the moment so I am quite aware that having all the back-end written in HTML will allow users to have access to the admin area using other OS. I would like to see what are the advantages and disadvantages of having WPF to manage the content of the website as its probably much easier to develop and manage (think about Live Writer).

• Rails App hangs after few requests

  - by Paddy

  I have Bitnami Rails stack installed on my Mac. To better explain my problem i created a simple scaffold based rails app with mysql as the backend. I can get to perform simple POST and GET requests for a while and after a few requests the app just hangs indefinitely. No exception caught or anything worthwhile in the development log to report this strange behavior. This is the last bit from the development log before the app froze: Processing WritedatasController#index (for 127.0.0.1 at 2010-03-30 20:38:51) [GET] [4;36;1mWritedata Load (0.7ms) [0m [0;1mSELECT * FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/index [4;35;1mWritedata Columns (2.9ms) [0m [0mSHOW FIELDS FROM `writedatas` [0m Completed in 99ms (View: 88, DB: 4) | 200 OK [http://localhost/writedatas] [4;36;1mSQL (0.2ms) [0m [0;1mSET NAMES 'utf8' [0m [4;35;1mSQL (0.1ms) [0m [0mSET SQL_AUTO_IS_NULL=0 [0m Processing WritedatasController#new (for 127.0.0.1 at 2010-03-30 20:38:52) [GET] [4;36;1mWritedata Columns (2.0ms) [0m [0;1mSHOW FIELDS FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/new Rendered writedatas/_form (5.9ms) Completed in 34ms (View: 25, DB: 2) | 200 OK [http://localhost/writedatas/new] [4;36;1mSQL (0.4ms) [0m [0;1mSET NAMES 'utf8' [0m [4;35;1mSQL (0.1ms) [0m [0mSET SQL_AUTO_IS_NULL=0 [0m Processing WritedatasController#index (for 127.0.0.1 at 2010-03-30 20:39:17) [GET] [4;36;1mWritedata Load (0.7ms) [0m [0;1mSELECT * FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/index [4;35;1mWritedata Columns (2.6ms) [0m [0mSHOW FIELDS FROM `writedatas` [0m Completed in 101ms (View: 90, DB: 4) | 200 OK [http://localhost/writedatas] It just hung at this point. And after this happens i have to restart the server, for it to hang again after few requests. This is the weirdest problem i have faced and i am truly stumped.

• Android Loading listview items from service results in hang

  - by Isaac Waller

  Hello, In my Android application, I have a ListActivity. This ListActivity uses a SimpleAdapter that I fill with items from my service. So, in my code, I do: MySuperCoolService.Binder serviceBinder = null; private ServiceConnection serviceConnection = new ServiceConnection() { public void onServiceConnected(ComponentName className, IBinder service) { Log.d(TAG, "Service connection: connected!"); serviceBinder = (MySuperCoolService.Binder)service; } public void onServiceDisconnected(ComponentName className) { Log.d(TAG, "Service connection: disconnected"); serviceBinder = null; } }; bindService(new Intent(this, MySuperCoolService.class), serviceConnection, BIND_AUTO_CREATE); while(serviceBinder==null) { Thread.Sleep(1000); } // now retrieve from service using binder and set list adapter This whole operation takes hardly any time (less than a second), so I want it to run in the UI thread. See my onCreate: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); fillDataUsingCodeAbove(); } The reason I want this to run in the UI thread is that if you have a list item selected, or you have scrolled to a certain position in the ListView, and you rotate the device or take out the keyboard or something (to trigger a configuration change) when my activity is restarted, Android will try to restore the state right after onCreate. But, if I run it in a separate thread, it will not. Also there is a cool fadein animation too :) The problem I am having with running it in the UI thread is that when I try to bind to the service, that service bind request gets put onto the message queue. But then when I go into my loop, I stop the message queue from looping. So my program hangs, because it's waiting for the service to get bound, and the service won't get bound until the loop ends. I have thought of putting Looper.loop() inside my loop, but that just hangs it at Looper.loop() (I don't know why.) Sorry for such a long question, Isaac Waller

• Fluent NHib causing visual studio 2010 hanging at runtime

  - by Berryl

  Just installed and migrated a 2008 solution on Vista ultimate 64 and .net 4.0. Everything builds and tests run surprisingly well but I got the hang description below while trying to run the app under SQLite. It turns out that the hang has got something to do when the call is made for FNH to build the session factory during a run, the only feedback I get is that the database wasn't configure properly without any inner exception. The strange part is that the exact code works perfectly under tests. Any clues? Description: A problem caused this program to stop interacting with Windows. Problem signature: Problem Event Name: AppHangB1 Application Name: devenv.exe Application Version: 10.0.30319.1 Application Timestamp: 4ba1fab3 Hang Signature: b9ed Hang Type: 6152 OS Version: 6.0.6002.2.2.0.256.1 Locale ID: 1033 Additional Hang Signature 1: 005de38e6b4bb3afd8e147932c6431cc Additional Hang Signature 2: d54c Additional Hang Signature 3: 05f671c8289bf8dd31e6ccfe265baa77 Additional Hang Signature 4: 784c Additional Hang Signature 5: c8207f54dadf3eb38dfcf1ae152f4229 Additional Hang Signature 6: ff83 Additional Hang Signature 7: 220932152f3f04fffb6ca3abf15e6dc6

• An Erroneous SQL Query makes browser hang until script timeout exceeded

  - by Jimbo

  I have an admin page in a Classic ASP web application that allows the admin user to run queries against the database (SQL Server 2000) Whats really strange is that if the query you send has an error in it (an invalid table join, a column you've forgotten to group by etc) the BROWSER hangs (CPU usage goes to maximum) until the SERVER script timeout is exceeded and then spits out a timeout exceeded error (server and browser are on different machines, so not sure how this happens!) I have tried this in IE 8 and FF 3 with the same result. If you run that same query (with errors) directly from SQL Enterprise Manager, it returns the real error immediately. Is this a security feature? Does anyone know how to turn it off? It even happens when the connection to the database is using 'sa' credentials so I dont think its a security setting :( Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.ActiveConnection = sConnectionString // run the query - this is for the admin only so doesnt check for sql safe commands etc. oRS.Open Request.Form("txtSQL") If Not oRS.EOF Then // list the field names from the recordset For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).name & "&nbsp;" Next // show the data for each record in the recordset While Not oRS.EOF For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).value & "&nbsp;" Next Response.Write "<br />" oRS.Movenext() Wend End If

• JS window.close() let IE hang

  - by p4bl0.666

  Hi all, for reason I won't bore you with, I'm writing an asp.net application that must open some pages in new browser windows. I managed to open them within a postback (don't ask why, I just needed to) with this code: script = String.Format(@"window.open(""{0}"", ""{1}"");", url, target); ScriptManager.RegisterStartupScript(page, typeof(Page), "Redirect", script, true); Now I have new windows each one with a button that should close it. I have simply an onclick="window.close()" (but that prompts me when I'm closing the browser) or window.open('','_self','');window.close() (horrible, I agree but it's the only way I found to avoid the JS prompt) On firefox it works perfectly but on IE7 (the browser our customers have) after 2-3 times I use that button to close the window I can't open other windows (in both cases, with or without the JS prompt). With the method above it does nothing, and with a <a href="mypage.aspx" target="_blank">click me</a> a new window is opened but hangs on loading (it doesn't even calls the Page_Load). What could be the cause? How can I solve this? Thank you.

• Converting a Visual Studio 2003 Web Project to a Visual Studio 2008 Web Application Project

  - by navaneeth

  This walkthrough describes how to convert a Visual Studio .NET 2002 or Visual Studio .NET 2003 Web project to a Visual Studio 2008 Web application project. The Visual Studio 2008 Web application project model is like the Visual Studio 2005 Web application project model. Therefore, the conversion processes are similar. For more information about Web application projects, see ASP.NET Web Application Projects. You can also convert from a Visual Studio .NET Web project to a Visual Studio 2008 Web site project. However, conversion to a Web application project is the approach that is supported, and gives you the convenience of tools to help with the conversion. For example, when you convert to a Visual Studio 2008 Web application project, you can use the Visual Studio Conversion Wizard to automate part of the process. For information about how to convert a Visual Studio .NET Web project to a Visual Studio 2008 Web site, see Common Web Project Conversion Issues and Solutions. There are two parts involved in converting a Visual Studio 2002 or 2003 Web project to a Visual Studio 2008 Web application project. The parts are as follows: Converting the project. You can use the Visual Studio Conversion Wizard for the initial conversion of the project and Web.config files. You can later use the Convert To Web Application command to update the project's files and structure. Upgrading the .NET Framework version of the project. You must upgrade the project's .NET Framework version to either .NET Framework 2.0 SP1 or to .NET Framework 3.5. This .NET Framework version upgrade is required because Visual Studio 2008 cannot target earlier versions of the .NET Framework. You can perform this upgrade during the project conversion, by using the Conversion Wizard. Alternatively, you can upgrade the .NET Framework version after you convert the project.   NoteYou can change a project's .NET Framework version manually. To do so, in Visual Studio open the property pages for the project, click the Application tab, and then select a new version from the Target Framework list. This walkthrough illustrates the following tasks: Opening the Visual Studio .NET project in Visual Studio 2008 and creating a backup of the project files. Upgrading the .NET Framework version that the project targets. Converting the project file and the Web.config file. Converting ASP.NET code files. Testing the converted project. Prerequisites    To complete this walkthrough, you will need: Visual Studio 2008. A Web site project that was created in Visual Studio .NET version 2002 or 2003 that compiles and runs without errors. Converting the Project and Upgrading the .NET Framework Version    To begin, you open the project in Visual Studio 2008, which starts the conversion. It offers you an opportunity to back up the project before converting it. NoteIt is strongly recommended that you back up the project. The conversion works on the original project files, which cannot be recovered if the conversion is not successful.To convert the project and back up the files In Visual Studio 2008, in the File menu, click Open and then click Project. The Open Project dialog box is displayed. Browse to the folder that contains the project or solution file for the Visual Studio .NET project, select the file, and then click Open. NoteMake sure that you open the project by using the Open Project command. If you use the Open Web Site command, the project will be converted to the Web site project format.The Conversion Wizard opens and prompts you to create a backup before converting the project. To create the backup, click Yes. Click Browse, select the folder in which the backup should be created, and then click Next. Click Finish. The backup starts. NoteThere might be significant delays as the Conversion Wizard copies files, with no updates or progress indicated. Wait until the process finishes before you continue.When the conversion finishes, the wizard prompts you to upgrade the targeted version of the .NET Framework for the project. To upgrade to the .NET Framework 3.5, click Yes. To upgrade the project to target the .NET Framework 2.0 SP1, click No. It is recommended that you leave the check box selected that asks whether you want to upgrade all Webs in the solution. If you upgrade to .NET Framework 3.5, the project's Web.config file is modified at the same time as the project file. When the upgrade and conversion have finished, a message is displayed that indicates that you have completed the first step in converting your project. Click OK. The wizard displays status information about the conversion. Click Close. Testing the Converted Project    After the conversion has finished, you can test the project to make sure that it runs. This will also help you identify code in the project that must be updated. To verify that the project runs If you know about changes that are required for the code to run with the new version of the .NET Framework, make those changes. In the Build menu, click Build. Any missing references or other compilation issues in the project are displayed in the Error List window. The most likely issues are missing assembly references or issues with dynamically generated types. In Solution Explorer, right-click the Web page that will be used to launch the application, and then click Set as Start Page. On the Debug menu, click Start Debugging. If debugging is not enabled, the Debugging Not Enabled dialog box is displayed. Select the option to add a Web.config file that has debugging enabled, and then click OK. Verify that the converted project runs as expected. Do not continue with the conversion process until all build and run-time errors are resolved. Converting ASP.NET Code Files    ASP.NET Web page files and user-control files in Visual Studio 2008 that use the code-behind model have an associated designer file. The files that you just converted will have an associated code-behind file, but no designer file. Therefore, the next step is to generate designer files. NoteOnly ASP.NET Web pages and user controls that have their code in a separate code file require a separate designer file. For pages that have inline code and no associated code file, no designer file will be generated.To convert ASP.NET code files In Solution Explorer, right-click the project node, and then click Convert To Web Application. The files are converted. Verify that the converted code files have a code file and a designer file. Build and run the project to verify the results of the conversion.

• Unity panel, and application functionality

  - by Dan

  From the Unity panel, left-clicking on an application that has multiple instances open displays the Spread Mode, but left-clicking on a solitary application does absolutely nothing. Personally, whenever I left-click on an open application, I expect it to either minimize or maximize, and I'd like to know if there's a way to get that functionality from Unity when left-clicking on a solitary application. I'm currently running Ubuntu 12.10. Thanks.

• Should a database server be in a different VM instance as an application?

  - by orokusaki

  I'm setting up a database server as a separate VM in my server so that I can control resources, and make backups of just that instance. I own a server that will reside in a colo soon. Is this the best way to approach my DB regarding scalability? Are there any security concerns? Do I listen at localhost still, even though it's a separate instance? And, is there any benefit to running your DB (PostgreSQL in my case) in the same machine as your application (web based SAAS application in my case)?

• How do I run JUnit tests from inside my java application?

  - by corgrath

  Is it possible to run JUnit tests from inside my java application? Are there test frameworks I can use (such as JUnit.jar?), or am I force to find the test files, invoke the methods and track the exceptions myself? The reason why I am asking is my application requires a lot of work to start launch (lots of dependencies and configurations, etc) and using an external testing tool (like JUnit Ant task) would require a lot of work to set up. It is easier to start the application and then inside the application run my tests. Is there an easy test framework that runs tests and output results from inside a java application or am I forced to write my own framework?

• Is it possible to run a hidden console application from a Windows service?

  - by norgepaul

  I've written a server in Delphi 2010 that needs to launch a console application every now and again to back up a database. The console application can send log information to the console window, but it is not required. This works fine when running as an application, but when run as a service I get an access violation when launching the console application. This is the case even if I launch it hidden (SW_HIDE). Is it possible to launch a hidden console application from a Windows service? The solution needs to work on XP, Vista and Windows 7.

• Application Demos in UPK

  - by [email protected]

  Over the years, User Productivity Kit has expanded to include solutions to many project challenges. As of UPK 3.6.1, solutions are provided for pre and post application go-live learning, application testing, system documentation, presentation output, and more. New in UPK 3.6.1 are additional features that can be used effectively for application demo purposes. This can come in handy when you need to do a demo but don't want to show or can't show the live application. Maybe you're doing a presentation for a group of project stakeholders and want to focus on the business workflow implemented by the application rather than the mechanics of using it. Or possibly, you need to show the application but you're disconnected from any network preventing you from running the live application. In any of these cases, a presentation aid that represents the live application is what's needed. Previous versions of the UPK topic player would allow you to do this but would always show those UPK user interface elements that help a user learn the application. When you're presenting the narrative live, the UPK bubbles can be a distraction. UPK 3.6.1 provides some new features that allow you to control whether the bubbles display. There are two ways to hide bubbles in a topic. The first is a topic property that allows you to control bubbles across the entire topic. There are 3 settings for the Show Bubbles topic property. The default setting is Use frame settings which allows you to control whether bubbles display on a frame by frame basis. When you choose Always, the bubbles will always display regardless of the frame setting. The final choice is Never. Choosing Never will hide every bubble in your topic with one setting change. As with Always, choosing Never will ignore the frame setting. The second way to control the bubbles is at the frame level. First ensure that the topic's Show Bubbles property is set to Use frame settings. Navigate to the frame on which you want to turn off the bubble and click the Display bubble for this frame button to turn off the bubble. When you play the topic, the bubble will no longer be displayed. Depending on your needs, you might also use another longstanding UPK feature that allows you to control whether the action area displays on a frame. Just click the Action area on/off button to toggle its display. I've found the frame properties to be useful beyond creating presentation aids. When creating "See It!" only topics for more advanced users, I may hide the bubbles on some of the more straightforward frames. For example, if I have a form where one needs to fill out an address, I may display the first bubble in the sequence and explain what the subsequent steps are doing. I then hide bubbles on the remaining frames which are the more mechanical steps of entering the address. We'd like to hear your thoughts on this new UPK feature. Use the comments below to tell us how you've used it. John Zaums Senior Director, Product Development Oracle User Productivity Kit

• Java Transaction Service without the application server

  - by johnny

  Is it possible to have a Java standalone application (no application server attached) that exposes some operations that a client can call and be the one to manage the transactions? I was thinking this application to expose JNDI resources and get a hold of a java:comp/UserTransaction from there, get also a bean from there and call methods A, B and C on it and coordinate the transaction from the client? The application I'm writing isn't complex enough so that I need a big application server around it so I'm thinking to have a standalone JTS inside it that the client could interact with from a transactions point of view. I don't have much experience with distributed transactions and don't really know how to tackle the issue. Is it even possible? Am I getting myself into something beyond what a mere mortal (programmer) can handle? How can I approach this?

• Silverlight Reporting Application Part 3.5 - Prism Background and WCF RIA [Series Intermission]

  Taking a step back before I dive into the details and full-on coding fun, I wanted to once again respond to a comment on my last post to clear up some things in regards to how I'm setting up my project and some of the choices I've made. Aka, thanks Ben. :) Prism Project Setup For starters, I'm not the ideal use case for a Prism application. In most cases where you've got a one-man team, Prism can be overkill as it is more intended for large teams who are geographically dispersed or in applications that have a larger scale than my Recruiting application in which you'll greatly benefit from modularity, delayed loading of xaps, etc. What Prism offers, though, is a manner for handling UI, commands, and events with the idea that, through a modular approach in which no parts really need to know about one another, I can update this application bit by bit as hiring needs change or requirements differ between offices without having to worry that changing something in the Jobs module will break something in, say, the Scheduling module. All that being said, here's a look at how our project breakdown for Recruit (MVVM/Prism implementation) looks: This could be a little misleading though, as each of those modules is actually another project in the overall Recruit solution. As far as what the projects actually are, that looks a bit like this: Recruiting Solution Recruit (Shell up there) - Main Silverlight Application .Web - Default .Web application to host the Silverlight app Infrastructure - Silverlight Class Library Project Modules - Silverlight Class Library Projects Infrastructure &Modules The Infrastructure project is probably something you'll see to some degree in any composite application. In this application, it is going to contain custom commands (you'll see the joy of these in a post or two down the road), events, helper classes, and any custom classes I need to share between different modules. Think of this as a handy little crossroad between any parts of your application. Modules on the other hand are the bread and butter of this application. Besides the shell, which holds the UI skeleton, and the infrastructure, which holds all those shared goodies, the modules are self-contained bundles of functionality to handle different concerns. In my scenario, I need a way to look up and edit Jobs, Applicants, and Schedule interviews, a Notification module to handle telling the user when different things are happening (i.e., loading from database), and a Menu to control interaction and moving between different views. All modules are going to follow the following pattern: The module class will inherit from IModule and handle initialization and loading the correct view into the correct region, whereas the Views and ViewModels folders will contain paired Silverlight user controls and ViewModel class backings. WCF RIA Services Since we've got all the projects in a single solution, we did not have to go the route of creating a WCR RIA Services Class Library. Every module has it's WCF RIA link back to the main .Web project, so the single Linq-2-SQL (yes, I said Linq-2-SQL, but I'll soon be switching to OpenAccess due to the new visual designer) context I'm using there works nicely with the scope of my project. If I were going for completely separating this project out and doing different, dynamically loaded elements, I'd probably go for the separate class library. Hope that clears that up. In the future though, I will be using that in a project that I've got in the "when I've got enough time to work on this" pipeline, so we'll get into that eventually- and hopefully when WCF RIA is in full release! Why Not use Silverlight Navigation/Business Template? The short answer- I'm a creature of habit, and having used Silverlight for a few years now, I'm used to doing lots of things manually. :) Plus, starting with a blank slate of a project I'm able to set up things exactly as I want them to be. In this case, rather than the navigation frame we would see in one of the templates, the MainRegion/ContentControl is working as our main navigation window. In many cases I will use theSilverlight navigation template to start things off, however in this case I did not need those features so I opted out of using that. Next time when I actually hit post #4, we're going to get into the modules and starting to get functionality into this application. Next week is also release week for the Q1 2010 release, so be sure to check out our annualWebinar Week (I might be biased, but Wednesday is my favorite out of the group). Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Determining an application's dependencies

  - by gpuguy

  I have developed an application using Windows Forms in C++ (IDE MS VC++ 2010). Some parts of the application also use MFC, and OpenCV. I want to send the application to my cleint for interim testing on his own machine. I have not developed any installer for the application, so I will be sending him an .EXE file. I want the client to not face any difficulties in replicating the environment, and therefore not lose any time. Can somebody suggest me what software (such as MS VC++ Runtime, .NET Framework, Windows SDK, etc.) should be installed on the client's machine for successfull testing of the application? Note: The OS (Windows 7) and hardware are exactly the same on both sides.

• Facebook abandonne HTML5 pour son application iOS, qualifiée de trop lente

  Facebook abandonne HTML5 pour son application iOS qualifiée de trop lente L'application Facebook pour iOS bien que pratique est lente, et souvent très lente même. D'après le New York Times, sur 38 000 personnes l'ayant noté, plus de 21 000 personnes n'ont accordé qu'une seule étoile à l'application, la qualifiant de lente, toujours en chargement, sujette à des crashs répétitifs, etc. Insensible à toutes ces remarques, Facebook a décidé de rendre son application plus rapide en réécrivant complètement celle-ci. Conséquence, le HTML5 qui avait été utilisé précédemment pour développer l'application autour d'une coque objective-c, afin d'utiliser la même base ...

• How to invite users to connect to your application using Facebook Application Development interfaces

  - by rabashani

  I think that this question already questioned, and probably the answer is here: http://wiki.developers.facebook.com/index.php/Notifications.send but the real problem is that facebook says: Facebook discontinued support for this method March 1, 2010. Calling this method returns error code 3 -- Unknown method. while, I couldn't find any other JS-api for the invitation, anyone know how we can invite users, using the JS api or the .net api? thanks.
