  • How important is it for me to pool my connections?

    - by Rio Mango
    It has been suggested to me that I rearrange my code to "pool" my ADO connections. On each web page I would open one connection and keep using the same open connection. But someone else told me that was important 10 years ago but is not so important now. If I make, let's say, 5 db calls on a web posting, is it problematic to be using 5 separate connections that I open/close?

  • Dynamically customize django admin columns ?

    - by tomjerry
    Is it possible to let the users choose / change dynamically the columns displayed in a object list in Django administration ? Things can surely be implemented "from scratch" by modifying the 'change_list.html' template but I was wondering if somebody has already had the same problem and/or if any django-pluggin can do that. Thanks in advance,

  • Is it possible to restrict how a method can be called in PHP?

    - by Ashley Ward
    Given that my class looks like this: class Methods{ function a(){ return 'a'; } function b(){ $this->a(); } function c(){ $this->a(); } } Is it possible to ensure that function a can only be called from function b? In the above example function c should fail. I could just include it in function b, but in the future I may want to let a() be called by some new functions (e.g. d() or e())

  • How can I hide a work item field from some users in TFS 2008?

    - by muerte
    I'm customizing work item templates in TFS 2008 through the PowerTools and I'm wondering is it possible to hide a field (or it's value) for certain users? For example, let's say I open TFS to my clients so they can submit feature requests. I'd like them to see the work item created, to see the history, changes etc. but I'd like to keep some of the field private and for our internal use. Is it possible?

  • Static member variable containing object instances

    - by tom
    I have the following: function Preferences() { } Preferences.players = { 'player1': new Player() } players is a static member variable of Preferences and I'm trying to make it an object containing an instance of a Player. However, it doesn't appear to let me do this. It seems like it will allow me to define players if I make it a non-static member variable however. Like so: function Preferences() { var players = { 'player1' : new Player() } } Is it possible to create a static member variable containing instances of an object in JS?
