  • how to use an mdf in App_Data with shared hosting

    - by name
    If I create a website that uses an mdf in App_Data with the connection string: Server=.\SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname; Trusted_Connection=Yes; what do I need to do to run the site in a shared hosting environment? Do I need to copy the contents of my mdf to the main SQL Server engine of my host? Is there a way to use the non-SQLExpress engine of my host and still keep my mdf in my App_Data?

  • How to change default conjunction with Lucene MultiFieldQueryParser

    - by Luke H
    I have some code using Lucene that leaves the default conjunction operator as OR, and I want to change it to AND. Some of the code just uses a plain QueryParser, and that's fine - I can just call setDefaultOperator on those instances. Unfortunately, in one place the code uses a MultiFieldQueryParser, and calls the static "parse" method (taking String, String[], BooleanClause.Occur[], Analyzer), so it seems that setDefaultOperator can't help, because it's an instance method. Is there a way to keep using the same parser but have the default conjunction changed?

  • Grails withCriteria testing

    - by Steve Wall
    Hello, I'd like to test a "withCriteria" closure and am not sure how to go about it. I see how to mock out the withCriteria call, but not test the code within the closure. When running the test that executes the "withCriteria", I keep getting a MissingMethodException, even though the code runs fine under the normal flow of execution. Any ideas? Thanks! Steve

  • Implementing a recently used or favorites dropdown in JComboBox

    - by Kevin Day
    I am looking for code that will add favorites / MRU type behavior to a JComboBox. I could code this myself, but it sure seems like someone else has probably already done it. I found the following (which looks exactly like what I want, but the source code is nowhere near complete): http://java.sys-con.com/node/36658 Any suggestions? I need to keep this relatively light, so I'd prefer to not use a component that's part of a monolithic widget library, and open source is preferred.

  • Maintaining content type pk integrity in a Django deployment

    - by hekevintran
    When you run syncdb in Django, the primary keys of the content types will be recomputed. If I create new models, the next time I run syncdb, the primary keys of the content types will be different. If I have an application running in production, how can I update the database with the new models and keep the integrity of content type pks?

  • What is on your desk?

    - by Jack
    I have read that what you keep on your desk is very influential in how you work and your level of productivity. I am trying to optimise the way that I work (I am a terrible procrastinator), and am curious what other programmers' desks look like. What do you have on your desk? Is there anything you deliberately avoid? There is no need to mention if you have things like computer, screen, mouse, keyboard, or speakers.

  • Why use NoSQL over Materialized Views?

    - by JustinT
    There has been a lot of talk recently about NoSQL. The #1 reason why I hear people use NoSQL is because they start to de-normalize their DBMS data so much so, to increase performance, that they end up with just one table with all of their data within that single table. With Materialized Views however, you can keep your data normalized, yet have it stored as a single table view for the same reasons why you'd use NoSQL. As such, why would someone use NoSQL over Materialized Views?

  • ASP.NET ascx.cs via GET

    - by Heavy Bytes
    Say I have this url: http://site.example/dir/ In this folder I have these files: test.ascx.cs and test.ascx Just to be clear, I am not a .NET developer. From a security point of view - why can't I access http://site.example/dir/test.ascx.cs and how secure is it to keep those files there? I assume IIS filters out request that query these kind of files, but can someone explain me this? Thank you.

  • Placing custom code in a System namespace

    - by David Brown
    Are there any best-practices that state custom code shouldn't be placed in a System namespace? Should System and its children be reserved for Microsoft code? I ask because I'm writing a class library that will be used across many projects and I'd like to keep things consistent by placing it in System.InteropServices (since it deals with P/Invoke).

  • SonarJ like tool for .NET

    - by J. Random Coder
    I'm looking for a tool like SonarJ but for .NET instead of Java. SonarJ helps you to find deviations between he architecture and the code within minutes. It can be integrated into your IDE to help you avoid the introduction of new architetural violations to your code base. You can also use it to maintain metric based software quality rules which will keep complexity under control. I googled and searched SO without satisfying results.

  • Using scroll on one memo edit to scroll on another as well

    - by Nathan Koop
    I've got two memoedits which are similar (in order to compare two records) I would like to keep the scrolling in synch to ease comparison. I had originally thought there would be an OnScroll event, but didn't see one, nor anything similar, the closest I saw was Spin, this handles some possibilities, but not all. I also didn't see a way to navigate the rows. I did see the ScrollToCaret method, but this doesn't do what I want. Any ideas?
