  • Open x86 'SOFTWARE' registry key on an x64 machine in C#

    - by Lance May
    I am trying to read the 32-bit HKLM\SOFTWARE registry key from a 64-bit (C#) application. This, of course, keeps redirecting my view to HKLM\SOFTWARE\Wow6432Node. According to what I've found this is doable, but I can't seem to find a .NET example anywhere. I just need to read; not write. Anyone ran across this before?

  • Maintaining software versions

    - by SCM
    I am preparing an Excel sheet in which I have to maintain the version number of different pieces of software developed at our company. Can anyone tell me what kind of information to save along with the version number in that sheet for different types of software? I know only one attribute that is version number, and if anything else so please let me know. Regards

  • LLBLGen Pro v3.0 with Entity Framework v4.0 (12m video)

    - by FransBouma
    Today I recorded a video in which I illustrate some of the database-first functionality available in LLBLGen Pro v3.0. LLBLGen Pro v3.0 also supports model-first functionality, which I hope to illustrate in an upcoming video. LLBLGen Pro v3.0 is currently in beta and is scheduled to RTM some time in May 2010. It supports the following frameworks out of the box, with more scheduled to follow in the coming year: LLBLGen Pro RTL (our own o/r mapper framework), Linq to Sql, NHibernate and Entity Framework (v1 and v4). The video I linked to below illustrates the creation of an entity model for Entity Framework v4, by reverse engineering the SQL Server 2008 example database 'AdventureWorks'. The following topics (among others) are included in the video: Abbreviation support (example: convert 'Qty' into 'Quantity' during name construction) Flexible, framework specific settings Attribute definitions for various elements (so no requirement for buddy-classes or messing with generated code or templates) Retrieval of relational model data from a database Reverse engineering of tables into entities, automatically placed in groups Auto-creation of inheritance hierarchies Refactoring of entity fields into Value Type Definitions (DDD) Mapping a Typed view onto a stored procedure resultset Creation of a Typed list (definition of a query with a projection) on a set of related entities Validation and correction of found inconsistencies and errors Generating code using one of the pre-defined presets Illustration of the code in vs.net 2010 It also gives a good overview of what it takes with LLBLGen Pro v3.0 to start from a new project, point it to a database, get an entity model, perform tweaks and validation and generate code which is ready to run. I am no video recording expert so there's no audio and some mouse movements might be a little too quickly. If that's the case, please pause the video. It's rather big (52MB). Click here to open the HTML page with the video (Flash). Opens in a new window. LLBLGen Pro v3.0 is currently in beta (available for v2.x customers) and scheduled to be released somewhere in May 2010.

  • Mobile Development- Obtaining development hardware - best practices?

    - by Zoot
    I'm looking to get into smartphone development, but there a quite a few options out there for platforms right now. (iOS/Android/WebOS/Bada/Symbian/MeeGo/WindowsMobile/JavaME) I'd like to have development hardware to test my code and the overall functionality of the devices. What is the best way to obtain and/or borrow hardware for development and testing? Are there rules of thumb to follow which apply to all companies and platforms? In this situation, I'm a single developer. Does this process change for a startup? A hackerspace? A small business? A large business? Thanks.

  • Múltiples clientes en el mismo Oracle UCM

    - by [email protected]
    Estamos muy activos con la implantación de plataformas ECM que den servicio a múltiples clientes. Consiguiendo 2 objetivos muy importantes:El cliente final puede pagar al proveedor por una plataformas ECM como servicio (SaaS). Y, lógicamente, se ahorra en complejidad y gastos de infraestructura, administración, formación, almacenamiento, etc...Hemos estado explicando estos días el modelo Master-Proxy de Oracle UCM con el que podemos implantar este tipo de plataformas. No siempre será la solución más adecuada porque a veces vamos a querer disponer de plataformas compartidas, pero con clientes completamente aislados. Siempre, la consola de migración nos permite exportar e importar componentes, metadatos, contenidos, workflows, etc... para que elijamos el modelo más adecuado para cada caso.Pero, ¿Cómo funciona?. Podéis ver en la imágen que se basa en la instalación de varias instancias de UCM y configurarlas de forma que varias de ellas se comporten como "Master" (digo varias para conseguir alta disponibilidad), y el resto se comporten como "Proxy" (también varias instancias de UCM pueden comportarse como un mismo "Proxy" permitiendo balancear la carga en función de que cada cliente requiera más o menos rendimiento). Esta configuración (que vemos en la imágen adjunta), nos permite:Delegar la gestión de usuarios de cada cliente. Los usuarios del Master podrán acceder a todos los Proxies, pero los usuarios de cada proxy sólo acceden a su repositorio.Delegar funcionalidad y componentes. Es posible configurar diferentes funcionalidades en cada proxy de forma que algunos servidores estén especializados en Web Content Management, otros en Document Management (por ejemplo).Diferentes modelos de metadatos. Podemos modelar unos tipos documentales generales para toda la plataforma y otros particulares diferentes en cada UCM "Proxy".Conseguir una centralización de búsquedas y acceso a repositorios de documentación con diferentes juegos de caracteres. Un UCM Master puede centralizar la búsqueda en UCM's proxy que alberguen documentación en diferentes juegos de caracteres (por ejemplo un UCM para documentación de idiomas "Western European" (inglés, español, francés, alemán,...) y otro UCM proxy bajo juego de caracteres "Asian" (japones, coreano, chino,...).Fuentes:Toda la información detallada se encuentra en la documentación de Oracle UCM, aquí:http://download.oracle.com/docs/cd/E10316_01/ouc.htmY en concreto, lo relativo a plataformas, en el documento "Planning and Implementation Guide", aquí:plan_implement_guide_10en.pdf

  • What are developer's problems with helpful error messages?

    - by Moo-Juice
    It continue to astounds me that, in this day and age, products that have years of use under their belt, built by teams of professionals, still to this day - fail to provide helpful error messages to the user. In some cases, the addition of just a little piece of extra information could save a user hours of trouble. A program that generates an error, generated it for a reason. It has everything at its disposal to inform the user as much as it can, why something failed. And yet it seems that providing information to aid the user is a low-priority. I think this is a huge failing. One example is from SQL Server. When you try and restore a database that is in use, it quite rightly won't let you. SQL Server knows what processes and applications are accessing it. Why can't it include information about the process(es) that are using the database? I know not everyone passes an Applicatio_Name attribute on their connection string, but even a hint about the machine in question could be helpful. Another candidate, also SQL Server (and mySQL) is the lovely string or binary data would be truncated error message and equivalents. A lot of the time, a simple perusal of the SQL statement that was generated and the table shows which column is the culprit. This isn't always the case, and if the database engine picked up on the error, why can't it save us that time and just tells us which damned column it was? On this example, you could argue that there may be a performance hit to checking it and that this would impede the writer. Fine, I'll buy that. How about, once the database engine knows there is an error, it does a quick comparison after-the-fact, between values that were going to be stored, versus the column lengths. Then display that to the user. ASP.NET's horrid Table Adapters are also guilty. Queries can be executed and one can be given an error message saying that a constraint somewhere is being violated. Thanks for that. Time to compare my data model against the database, because the developers are too lazy to provide even a row number, or example data. (For the record, I'd never use this data-access method by choice, it's just a project I have inherited!). Whenever I throw an exception from my C# or C++ code, I provide everything I have at hand to the user. The decision has been made to throw it, so the more information I can give, the better. Why did my function throw an exception? What was passed in, and what was expected? It takes me just a little longer to put something meaningful in the body of an exception message. Hell, it does nothing but help me whilst I develop, because I know my code throws things that are meaningful. One could argue that complicated exception messages should not be displayed to the user. Whilst I disagree with that, it is an argument that can easily be appeased by having a different level of verbosity depending on your build. Even then, the users of ASP.NET and SQL Server are not your typical users, and would prefer something full of verbosity and yummy information because they can track down their problems faster. Why to developers think it is okay, in this day and age, to provide the bare minimum amount of information when an error occurs? It's 2011 guys, come on.

  • Is JSF really ready to deliver high performance web applications?

    - by aklin81
    I have heard a lot of good about JSF but as far as I know people also had lots of serious complains with this technology in the past, not aware of how much the situation has improved. We are considering JSF as a probable technology for a social network project. But we are not aware of the performance scores of JSF neither we could really come across any existing high performance website that had been using JSF. People complain about its performance scalability issues. We are still not very sure if we are doing the right thing by choosing jsf, and thus would like to hear from you all about this and take your inputs into consideration. Is it possible to configure JSF to satisfy the high performance needs of social networking service ? Also till what extent is it possible to survive with the current problems in JSF.

  • Chester Devs Presentation and source code &ndash; &lsquo;Event Store - an introduction to a DSD for event sourcing and notifications&rsquo;

    - by Liam Westley
    Originally posted on: http://geekswithblogs.net/twickers/archive/2013/11/11/chester-devs-presentation-and-source-code-ndash-lsquoevent-store.aspxThank you everyone at Chester Devs Thanks to Fran Hoey and all the people from Chester Devs. It was a hard drive up and back but the enthusiasm of the audience, with some great questions does make it worthwhile. Presentation and source code My presentation, source code, Event Store runners and text files containing the various command line parameters used for curl is now available on GitHub; https://github.com/westleyl/ChesterDevs-EventStore. Don’t worry if you don’t have a GitHub account, you don’t need one, you can just click on the Download Zip button on the right hand menu to download all the files as a single ZIP file.  If all you want is the PowerPoint presentation, go to https://github.com/westleyl/ChesterDevs-EventStore/blob/master/Powerpoint/Huddle-EventStore.pptx, and click on the View Raw button. Downloading and installing Event Store and Tools Download Event Store http://download.geteventstore.com – I unzipped these files into C:\EventStore\v2.0.1 Download Curl from http://curl.haxx.se/download.html – I downloaded Win64 Generic (with SSL) and unzipped these files into C:\curl version 7.31.0 Running the tools I used in my presentation Demonstration 1 (running Event Store) You can use one of my Event Store runner command files to run the single node version of Event Store, using default ports of 2213 for HTTP and 1113  for TCP, and with a wildcard HTTP pattern.  Both take a single command line parameter to specify the location of the data and log files.  The runners assume the single node executable is located in C:\EventStore\v2.0.1, and will placed data files and logs beneath C:\EventStore\Data, i.e. RunEventStore.cmd TestData1 This will create data files in C:\EventStore\Data\TestData1\Data and log files in C:\EventStore\Data\TestData1\logs. If, when running Event Store you may see the following message, [03288,15,06:23:00.622] Failed to start http server Access is denied You will either need to run Event Store in an administrator console window, or you can use the netsh command to create a firewall permission to allow HTTP listening (this will need to be run, once, in an administrator console window), netsh http add urlacl url=http://*:2213/ user=liam You can always delete this later by running the delete; netsh http delete urlacl url=http://*:2213/ If you want to confirm that everything is running OK, open the management console in a browser by navigating to http://127.0.0.1:2213. If at any point you are asked for a user name and password use the default of ‘admin’/‘changeit’. Demonstration 2 (reading and adding data, curl) In my second demonstration I used curl directly from the console to read streams, write events and then read back those events. On GitHub I have included is a set of curl commands, CurlCommandLine.txt, and a sample data file, SampleData.json, to load an event into a DDDNorth3 stream. As there is not much data in the Event Store at this point I used the $stats-127.0.0.1:2113 which is a stream containing performance statistics for Event Store and is updated every 30 seconds (default). Demonstration 3 (projections) On GitHub I have included a sample projection, Projection-ByRoom.txt, which will create streams based on the room on which a session was held on the DDDNorth3 agenda. Browse to the management console, http://127.0.0.1:2213.  Click on Projections, New Projection, give it a name, Sessions-ByRoom, and copy in the JavaScript in the Projection-ByRoom.txt file.  Select Continuous, tick Emit Enabled and then click on Post. It should run immediately. You may by challenged for the administration login for the management console, if so use the default user name and password; 'admin'/'changeit'. Demonstration 4 (C# client) The final demonstration was the Visual Studio 2012 project using the Event Store client – referenced directly as C:\EventStore\v2.0.1\EventStore.ClientAPI.dll, although you can switch this to the latest Event Store client NuGet package. The source code provides a console app for viewing projections with the projection manager (HTTP connection), as well as containing a full set of data for the entire DDDNorth3 agenda.  It also deals with the strategy for reading newest events backwards to older events and ignoring older events that have been superseded.

  • Recommendation for Regex editor?

    - by Tim
    I asked for recommendations for Regex editors on stackoverflow a while ago. Following is one of the replies: What is "good" depends on what is most useful to you. For me, though, these are the key features for a good regex editor (besides the ability to test and create regular expressions, of course, which is a prerequisite to be called a "regex editor" :-) : Displays matches hierarchically with captured groups. Explains/analyzes an entered regex in plain English, showing a hierarchical tree. Translates your regex into code for a language of your choice. RegexBuddy, as @Max mentioned, does all these but there is also a free alternative, Expresso that also does them very well. These two utilities are the only ones I have found with the crucial ability to explain a regex. The features sound very attractive to me. But later I found the two are for Windows. I tried to install Expresso, the free one, via Wine, but met some trouble, about which I asked in another post. So I was wondering if in Ubuntu there are some applications comparable to RegexBuddy and Expresso? If it is required to install .NET Framework in order to install Expresso, is it still worth to install Expresso on Ubuntu? Thanks and regards!

  • How to Install vaio-control-center from source?

    - by KasiyA
    I have a problem about turning off keyboard backlight that I asked here with no useful answers. After searching on internet I find a package for vaio control center and downloaded it from here, I don't know how to install it. This is the output of trying one solution: USER@XXXXpc:~/vaio-control-center-0.1$ ls compile Makefile run vaio-control-center vcc COPYING moc_main_window.cpp ui_main_window.h vaio-control-center.pro USER@XXXXpc:~/vaio-control-center-0.1$ ./compile make: *** No rule to make target `/usr/share/qt/mkspecs/linux-g++-64/qmake.conf', needed by `Makefile'. Stop. USER@XXXXpc:~/vaio-control-center-0.1$ ./run ./run: 3: ./run: ./vaio-control-center: not found USER@XXXXpc:~/vaio-control-center-0.1$ Updated I tried also with @pandya's suggestion from here. and the output is as follows: root@user-pc:/# cd /home/user/vaio-f11-linux.control-center root@user-pc:/home/user/vaio-f11-linux.control-center# ls compile COPYING resource.qrc run sony-acpid vaio-control-center.pro vcc root@user-pc:/home/user/vaio-f11-linux.control-center# ./compile -su: ./compile: Permission denied root@user-pc:/home/user/vaio-f11-linux.control-center# sudo ./compile sudo: ./compile: command not found root@user-pc:/home/user/vaio-f11-linux.control-center# gksudo ./compile root@user-pc:/home/user/vaio-f11-linux.control-center# <----- nothing happened here root@user-pc:/home/user/vaio-f11-linux.control-center# ./run -su: ./run: Permission denied root@user-pc:/home/user/vaio-f11-linux.control-center# sudo ./run sudo: ./run: command not found root@user-pc:/home/user/vaio-f11-linux.control-center# gksudo ./run root@user-pc:/home/user/vaio-f11-linux.control-center# <----- nothing happened here root@user-pc:/home/user/vaio-f11-linux.control-center# and after running that I didn't see any affect on keyboard backlight.

  • How should you approach supporting rapidly-updating web browsers?

    - by Schnapple
    Today, Firefox 5 was released. If all goes according to plan, Firefox 7 will be out by the end of the year. Firefox has adopted the Google Chrome development model wherein version numbers are largely unimportant and so just supporting "the latest (publicly available) one" is probably the best strategy. But how do you best test that? As my QA guys have pointed out, if you tell the client that you support "the latest version" but a version comes out that breaks your site, then you have a problem because now you've stated you support a web browser you don't. And since both Firefox and Chrome now update themselves automatically, the average person probably has no clue or care what version they're running. And having them either not upgrade or roll back is nontrivial. I'm finding there are a number of organizations that mandate their employees use IE (the head of IT subscribes to the Microsoft school of thought), or mandate their employees use Firefox (the head of IT subscribes to the IE-is-insecure school of thought), so Chrome updating constantly was a non-issue. But now that Firefox is a member of that club, I can see this becoming a bigger issue soon. My guess, in the case of Firefox, would be that the Aurora channel is the key, but what is the best way to approach testing it? Should we fix anything that comes up as an issue in Aurora, or should we wait until closer to the scheduled release? Do people automate this sort of thing?

  • GTK equivalent to MS Spy++

    - by zetah
    Spy++ comes with paid version of MS Visual Studio as utility that gives you a graphical view of the system’s processes, threads, windows, and window messages. and it's not only utility on Win32 that offers this feature, but I use it as popular example. It lists all UI elements of all running applications, and user can use "Find Tool" to locate UI element of interest and get response dialog with versatile information about that object, like UI control name, text contents, and many other data of potential interest to a programmer. I'm interested in similar GTK application which can at least return GTK UI element (widget) name and extracted text contents of that element of arbitrary running process. I couldn't find anything related using Google

  • 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)

  • Configuring thouands of related products in Magento?

    - by Anonymous -
    I'm at a stage with a Magento store I'm developing where I've added all the products (all 6000 of them) and now would like to configure related products to up my conversion rate a bit. I was wondering if there was an extension anybody knew of that functions similarly to this one, with the most current version of Magento (Community Edition, 1.6.1). If not, would anyone be able to provide some pointers for writing a script that will run through each product and add 1-5 related products. I have a fairly basic idea of taking product title text and just doing a simple text similarity query between other product titles for now, just to get some related products up there, but the Magento database isn't making a terribly large amount of sense. Thanks to anyone who can shed some light on this. :)

  • Nice network diagram editor?

    - by Nicolas Raoul
    Writing a commercial proposal, I want to create a nice graphic showing the clients the architecture I thought of for their IT network, with servers, network connections, firewall, load-balancing, etc. For years I have been using dia, but I am tired of it, the results are not satisfying, very few network elements are available, and each element's graphic representation is really ugly. Question: How to create nice network diagrams? If a better set of elements was available for dia, that would be a solution.
