  • Getting maximum value of float in SQL programatically

    - by Axarydax
    Is there an method for programatically (in T-SQL) retrieving the maximum (and minimum) value of a datatype? That it would act like float.MaxValue in C#. I would like to use it in some selection when the parameter does not equal any actual values in the database, so I would use something like declare @min float declare @max float /*fill @min and @max, can be null if undefined*/ select * from foo where bar between isnull(@min,0 ), isnull(@max,max(float)/*magic*/) Thanks

  • What's the simplest way to make a scrollable list of controls with labels?

    - by Jon Cage
    Using C++/CLI and Windows Forms, I'm trying to make a simple scrollable list of labelled text controls as a way of displaying some data fields. I'm having trouble making a TableLayoutPanel scrollable - every combination of properties I've tried seems to result in some really peculiar side effects. So I have two questions: Is this the best way to do it. If it is a reasonable approach, what magic combination of settings should I apply to the table layout panel to make it play ball?

    - by DeadMG
    How can I implement tail calls in a custom virtual machine? I know that I need to pop off the original function's local stack, then it's arguments, then push on the new arguments. But, if I pop off the function's local stack, how am I supposed to push on the new arguments? They've just been popped off the stack.

  • What jquery rails 3 tutorial has worked well for you?

    - by finneycanhelp
    Hi! I have looked at several tutorials involving rails 3 and jquery. The tutorial at http://www.blog.bridgeutopiaweb.com/post/how-to-use-jquery-for-rails-3/ looked promising. However, I get the errors of document.on is not a function and $("a[data-remote=true]").livequery is not a function I get the feeling that I should look at another tutorial or just use jquery raw and not install a ruby gem for jquery. Any advice? Thanks!

  • Lambda functions

    - by Oden
    Hey, I'm really interested in the way of using lambda functions. Does it make sense to use them in a high-level programming language? If yes, why? Is this really just a function embedded in a function (like this) or is there more behind?

  • Fastest way to find the largest power of 10 smaller than x

    - by peoro
    Is there any fast way to find the largest power of 10 smaller than a given number? I'm using this algorithm, at the moment, but something inside myself dies anytime I see it: 10**( int( math.log10(x) ) ) # python pow( 10, (int) log10(x) ) // C I could implement simple log10 and pow functions for my problems with one loop each, but still I'm wondering if there is some bit magic for decimal numbers.

  • Javascript: 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?

    - by brent
    Backbone's documentation states: The events property may also be defined as a function that returns an events hash, to make it easier to programmatically define your events, as well as inherit them from parent views. How do you inherit a parent's view events and extend them? Parent View var ParentView = Backbone.View.extend({ events: { 'click': 'onclick' } }); Child View var ChildView = ParentView.extend({ events: function(){ ???? } });
