  • check if sqlserver is installed on a machine thro C#

    - by Skun
    Hey ! I am making an application which is a user interface to access 2 types of databases - SQLite and MSSQL server. The thing is, SQLite doesnt need to be "installed" since its just a flatfile database, but on the other hand, SQLserver (Express/normal) need to be installed before use. My Question is simple: Is there a way by which i can find out if an instance of SQLserver has been installed on the local machine by using a C# program?

  • How to structure Javascript programs in complex web applications?

    - by mixedpickles
    Hi there. I have a problem, which is not easily described. I'm writing a web application that makes heavy usage of jquery and ajax calls. Now I don't have experience in designing the architecture for javascript programms, but I realize that my program has not a good structure. I think I have to many identifiers referring to the same (at least more or less) thing. Let's have an exemplary look at an arbitrary UI widget: The eventhandlers use DOM elements as parameters. The DOM element represents a widget in the browser. A lot of times I use jQuery objects (I think they are basically a wrapper around DOM elements) to do something with the widget. Sometimes they are used transiently, sometimes they are stored in a variable for later purposes. The ajax function calls use strings identifiers for these widgets. They are processed server side. Beside that I have a widget class whose instances represents a widget. It is instantiated through the new operator. Now I have somehow four different object identifiers for the same thing, which needs to be kept in sync until the page is loaded anew. This seems not to be a good thing. Any advice?

  • Exam 71-515: TS: Web Applications Development with Microsoft .NET Framework 4

    - by Ricardo Peres
    I took the 71-515 exam today. 85 questions, 240 minutes. Here are some notes: Great number of jQuery questions, mostly having to do with AJAX Lots of MVC 2 questions also A number of classic ASP.NET web forms, of which only a few were related with the new 4 features Some Entity Framework Some plain old JavaScript, like, changing an image dynamically I think I did OK. As with my previous exam, I still don't know if I passed or not, will have to wait for the end of the beta period.

  • Need help with PHP web app bootstrapping error potentially related to Zend [migrated]

    - by Matt Shepherd
    I am trying to get a program called OpenFISMA running on an Ubuntu AMI in AWS. The app is not really coded on the Ubuntu platform, but I am in my comfort zone there, and have tried both CentOS and OpenSUSE (both are sort of "native" for the app) for getting it working with the same or worse results. So, why not just get it working on Ubuntu? Anyway, the app is found here: www.openfisma.org and an install guide is found here: https://openfisma.atlassian.net/wiki/display/030100/Installation+Guide The install guide kind of sucks. It doesn't list dependencies in any coherent way or provide much of any detail (does not even mention Zend once on the entire page) so I've done a lot of work to divine the information I do have. This page provided some dependency inf (though again, Zend is not mentioned once): https://openfisma.atlassian.net/wiki/display/PUBLIC/RPM+Management#RPMManagement-BasicOverviewofRPMPackages Anyway, I got all the way through the install (so far as I could reconstruct it). I am going to the login page for the first time, and there should be some sort of bootstrapping occurring when I load the page. (I am not a programmer so I have no idea what it is doing there.) Anyway, I get a message on the web page that says: "An exception occurred while bootstrapping the application." So, then I go look in /var/www/data/logs/php.log and find this message: [22-Oct-2013 17:29:18 UTC] PHP Fatal error: Uncaught exception 'Zend_Exception' with message 'No entry is registered for key 'Zend_Log'' in /var/www/library/Zend/Registry.php:147 Stack trace: #0 /var/www/public/index.php(188): Zend_Registry::get('Zend_Log') #1 {main} thrown in /var/www/library/Zend/Registry.php on line 147 This occurs every time I load the page. I gather there is an issue related to registering the Zend_Log variable in the Zend registry, but other than that I really have no idea what to do about it. Am I missing a package that it needs, or is this app not coded to register the variables properly? I have no clue. Any help is greatly appreciated.

  • Enabling 32-Bit Applications on IIS7 (also affects 32-bit oledb or odbc drivers) [Solved]

    - by Humprey Cogay, C|EH
    We just bought a new Web Server, after installing Windows 2008 R2(which is a 64bit OS and IIS7), SQL Server Standard 2008 R2 and IBM Client Access for V5R3 with its Dot Net Data Providers, I tried deploying our new project which is fully functional on an IIS6 Based Web Server, I encountered this Error The 'IBMDA400.DataSource.1' provider is not registered on the local machine. To remove the doubt that I still lack some Software Pre-Requesites or version conflicts  since I encountered some erros while installing my IBM Client Access, I created a Connection Tester which is Windows App that accepts a connection string as a parameter and verifies if that parameter is valid. After entering the Proper Conn String I tried hitting the button and the Test was Succesful. So now I trimmed my suspects to My Web App and IIS7. After Googling around I found this post by a Rakki Muthukumar(Microsoft Developer Support Engineer for ASP.NET and IIS7) http://blogs.msdn.com/b/rakkimk/archive/2007/11/03/iis7-running-32-bit-and-64-bit-asp-net-versions-at-the-same-time-on-different-worker-processes.aspx So I tried scouting on IIS7's management console and found this little tweak under the Application Pool where my App is a member of. After changing this parameter to TRUE Yahoo (although I'm a Google kind of person) the Web App Works .......

  • Transactions in LINQ to SQL applications

    - by nikolaosk
    In this post I would like to talk about LINQ to SQL and transactions.When I have a LINQ to SQL class I always get asked this question, "How does LINQ treat Transactions?". When we use the DeleteOnSubmit() method or the InsertOnSubmit() method, all of those commands at some point are translated into T-SQL commands and then are executed against the database. All of those commands live in transactions and they follow the basic rules of transaction processing. They do succeed together or fail together...(read more)

  • The Scoop: Oracle E-Business Suite Support on 64-bit Linux

    - by Terri Noyes
    This article addresses frequently asked questions about Oracle E-Business Suite (EBS) 64-bit Linux support.Q:  Which 64-bit Linux OSs are supported for EBS? A: Beginning with Release 12, we support the following 64-bit operating systems for both application and database tiers on x86-64 servers:Oracle Enterprise Linux Red Hat Enterprise Linux SUSE Linux Enterprise Server For EBS Release 11i (and again in Release 12), when the application tier is installed on a certified platform, additional platforms (including the above) may be used for a 64-bit database tier on x86-64 servers. This is an example of a mixed platform architecture (Release 12), or a Split Configuration (Release 11i). Q:  I understand that the EBS application tier code is 32-bit, even for the 64-bit Linux OS -- is this the case?A: It is true that the majority of executables provided as part of our release media on the application tier are 32-bit (as are the Fusion Middleware libraries and objects they depend on).  However, the 'Planning' products have large memory requirements and therefore are 64-bit compiled to take advantage of the larger memory space afforded by the 64-bit OS'es.

  • ASP.NET 4 Hosting :: How to Debug Your ASP.NET Applications

    - by mbridge
    Remote debugging of a process is a privilege, and like all privileges, it must be granted to a user or group of users before its operation is allowed. The Microsoft .NET Framework and Microsoft Visual Studio .NET provide two mechanisms to enable remote debugging support: The Debugger Users group and the "Debug programs" user right. Debugger Users Group When you debug a remote .NET Framework-based application, the Debugger on your computer must communicate with the remote computer using DCOM. The remote server must grant the Debugger access, and it does this by granting access to all members of the Debugger Users group. Therefore, you must ensure that you are a member of the Debugger Users group on that computer. This is a local security group, meaning that it is visible to only the computer where it exists. To add yourself or a group to the Debugger Users group, follow these steps: 1. Right-click the My Computer icon on the Desktop and choose Manage from the context menu. 2. Browse to the Groups node, which is found under the Local Users and Groups node of System Tools. 3. In the right pane, double-click the Debugger Users group. 4. Add your user account or a group account of which you are a member. Debug Programs User Right To debug programs that run under an account that is different from your account, you must be granted the "Debug programs" user right on the computer where the program runs. By default, only the Administrators group is granted this user right. You can check this by opening Local Security Policy on the computer. To do so, follow these steps: 1. Click Start, Administrative Tools, and then Local Security Policy. 2. Browse to the User Rights Assignment node under the Local Policies node. 3. In the right pane, double-click the "Debug programs" user right. 4. Add your user account or a group account of which you are a member.

  • Web Development Trends: Mobile First, Data-Oriented Development, and Single Page Applications

    - by dwahlin
    I recently had the opportunity to give a keynote talk at an Intel conference about key trends in the world of Web development that I feel teams should be taking into account with projects. It was a lot of fun and I had the opportunity to talk with a lot of different people about projects they’re working on. There are a million things that could be covered for this type of talk (HTML5 anyone?) but I only had 60 minutes and couldn’t possibly cover them all so I decided to focus on 3 key areas: mobile, data-oriented development, and SPAs. The talk was geared toward introducing people (many who weren’t Web developers) to topics such as mobile first development (demos showed a few tools to help here), responsive design techniques, data binding techniques that can simplify code, and Single Page Application (SPA) benefits. Links to code demos shown during the presentation can be found at the end of the slide deck. Web Development Trends - What's New in the World of Web Development by Dan Wahlin

  • Introducing Kiddo: A Ruby DSL for building simple WPF and Silverlight applications

    - by fdumlao
    Read the original article here... As a long time Ruby lover and deep rooted .NET supporter, I was probably more psyched than anyone I knew when IronRuby 1.0 was finally released. I immediately grabbed and started building some apps with it to see where the boundaries were going to lie between IronRuby and ruby.exe, and so far I've been pleasantly surprised by how many things just work as I'd expect. I then started to try out some of my favorite libs that I was sure would not work with IronRuby, and I wasn't surprised at all when _why's amazing Shoes library didn't work. Being somewhat familiar with Shoes (it's a great DSL for building simple UIs in Ruby) I felt it wouldn't be that difficult to port it over and as it turned out, someone else had already started the work. As cool as this was, I was never quite satisfied with good 'ol shoes. While it was quite complete, it lacked simple extensibility points, and although easy, it wasn't quite "kid friendly". At the same time on the .NET side of the fence, IronRuby could easily compile XAML to create WPF and Silverlight UIs, but trying to do it declaratively in plain Ruby was no fun at all. And so, the Shoes-inspired, WPF/Silverlight GUI DSL was born. (and it lives here: http://bitbucket.org/fdumlao/kiddo/src) Introducing Kiddo Tell you what. Let's start with a quick code example first. We'll build a useful app that we can use to quickly reverse strings whenever we need it. Read the complete article here...

  • [MINI HOW-TO] Create Keyboard Shortcuts to Applications in Windows

    - by Asian Angel
    Do you need just one or a few special keyboard shortcuts for your favorite program(s)? A quick modification to program shortcuts will get you up and running without installing additional software. Creating New Keyboard Shortcuts Go to the start menu shortcut for the program, right-click on it, and select properties. When the properties window opens click in the shortcut key text area. All that you need to do is choose an appropriate letter for the program (i.e. O for Opera, E for Editra, etc.) and type it in the blank. You will not need to type any other keys or combination in…the “Ctrl + Alt +” will be automatically entered for you as soon as you type the letter in. Click OK to finish creating the new keyboard shortcut. Those new keyboard shortcuts will speed up access to your favorite software. Another example from our system using “I” for Iron Browser. Certainly much quicker than using the start menu. Conclusion If you only need one or just a few special keyboard shortcuts then this method provides a quick and simple solution.
