  • Ninject and DataContext disposal

    - by Bas
    I'm using Ninject to retrieve my DataContext from the kernel and I was wondering if Ninject automatically disposes the DataContext, or how he handles the dispose() behaviour. From own experiences I know disposing the datacontext is pretty important and that whenever you create a direct object of the DataContext (as in: new DataContext()) you should use a using() block. My question thus is: When im retrieving my DataContext from the kernel, should I still have to use a using() block? Or does Ninject fix this for me?

  • Wordpress databse insert() and update() - using NULL values

    - by pygorex1
    Wordpress ships with the wpdb class which handles CRUD operations. The two methods of this class that I'm interested in are the insert() (the C in CRUD) and update() (the U in CRUD). A problem arises when I want to insert a NULL into a mysql database column - the wpdb class escapes PHP null variables to empty strings. How can I tell Wordpress to use an actual MySQL NULL instead of a MySQL string?

  • ASP.Net MVC - What replaces events to support loose coupling?

    - by James
    What feature(s) of ASP.Net MVC can replace the way events can be used in Webforms to support loosely coupled components. For example, take a simple pager control: A page number is clicked Pager fires off a "PageChange" event with the new page number This subscribing page/control received the event and handles initiating a call to fetch and bind new data. What tools are available in ASP.Net MVC to support Loose coupling Component re-usability Separation of logic for a single page/view (such a very complex "portal" type page).

    I've been trying to do some PHP work on my snow leopard machine.. but I've found issues when I need to use PEAR packages (as symfony handles its php plugins with PEAR).

  • multiple Thrift services on one transport

    - by kert
    Just seeking confirmation here : apache Thrift protocol does not seem to support running multiple services on one transport endpoint ? ( a socket, file, whatever ) I cant seem to figure out how to do something like this in Thrift: service otherService { void dosomething() } service rootService { otherService getOtherService() } There does not seem to be any concept of passing in and out service handles, ultimately limited by the protocol. Looks like you can not run two services on one transport pipe. Correct ?

  • Best Practice for Utilities Class?

    - by Sonny Boy
    Hey all, We currently have a utilities class that handles a lot of string formatting, date displays, and similar functionality and it's a shared/static class. Is this the "correct" way of doing things or should we be instanciating the utility class as and when we need it? Our main goal here is to reduce memory footprint but performance of the application is also a consideration. Thanks, Matt PS. We're using .NET 2.0

  • Correct order of overrides for a composite control based on an abstract one

    - by mattdwen
    I'm writing a set of C# composite web server controls for displaying dialog boxes. I want to have one abstract class which handles the basic layout and things like titles of the control, then have a set of derived ones which render child controls at a specific point. I forsee three distincts methods: renderOpeningHtml handled by the abstract class, renderCustomControls as done by the derived class, and renderClosingHtml by the abstract class again, except I can't figure the life cycle of a CompositeControl and what methods to use when.

    - by davemackey
    Lets say I have a class like this in class1.vb: Public Class my_class Public Sub my_sub() Dim myvar as String myvar = 10 Session("myvar") = myvar End Sub End Class Then I have a ASP.NET page with a code-behind file, default.aspx and default.aspx.vb and I want to call my_class.

  • C printf in Delphi?

    - by kroimon
    Hi there! Does anyone know a 100% clone of the C/C++ printf for Delphi? Yes, I know the System.Format function, but it handles things a little different. For example if you want to format 3.14 to "003" you need "%03d" in C, but "%.3d" in Delphi. I have an application written in Delphi which has to be able to format numbers using C format strings, so do you know a snippet/library for that? Thanks in advance!

  • Concept of GUI's - Centralized or decentralized

    - by wvd
    Hello all, Since a few months I've been learning Erlang, and now it was time to do some basic GUI. After some quick research I saw there was an interesting library called 'wxi' (based on Fudgets of Haskell) which uses a different approach on GUI's. No central loop, every widget processes it's own events and handles it's own data. What do you guys think about this? It looks like it kind of can be efficient in languages such as Erlang, and it's an interesting approach. William van Doorn

  • Escape Single Quotes in Template Toolkit

    - by Zach
    Do you ever escape single quotes in template toolkit for necessary javascript handlers? If so, how do you do it. [% SET s = "A'B'C" %] <a href="/abc.html" onclick="popup('[% s | html_entity %]')">ABC</a> html_entity obviously doesn't work because it only handles the double quote. So how do you do it?
