  • Join two results in Powershell

    - by Hinek
    I've got two CMDlets that return lists of objects. One returns objects of the type SPSolution, which contains the property Id, the other returns objects of the type SPFeature with a property SolutionId. Now I want to join/merge this data something like this: $f = Get-Feature $s = Get-Solution $result = <JOIN> $f $s <ON> $f.SolutionId = $s.Id <SELECT> FeatureName = $f.DisplayName, SolutionName = $s.Name

  • Update one list from another

    - by lacqui
    I have two multi-select lists in HTML - one of categories, and another of items. What I want is that, when an item selected in the "category" list, everything in the "items" list from that category is also selected. For example, if "Categories" contains "Animal", "Mineral", and "Vegetable", and "Items" contains "Dog", "Cat", "Monkey", "Diamond", "Granite", "Carrot", "Tomato": If "Animal" is selected in one list, "Dog", "Cat", and "Monkey" should be selected; any other selections should remain as they are. I'm using a Symfony PHP backend on the server, if that makes any difference

  • How to output items in Order in MySQL?

    - by RailsRor
    I have a column called "menu_order" which has no default value. When I select the contents of this column using the following select statement: SELECT * FROM categories ORDER BY menu_order ASC It lists the category items that have nothing as their menu order first and then the one's that have 1's and 2's and 3's. Is there any way to prevent SQL from take nothing to come before numbers when I am trying to list things in order? So for example, if I have: cat_name | menu_order ---------------------- Lunch | 1 Dinner | And I perform my query, the output should be: Lunch Dinner Not: Dinner Lunch

  • Most efficient way to draw circles for polygon outlines

    - by user146780
    I'm using OpenGL and was told I should draw circles at each vertex of my outline to get smoothness. I tried this and it works great. The problem is speed. It crippled my application to draw a circle at each vertex. I'm not sure how else to fix the anomaly of my outlines other than circles, but using display lists and trying with vertex array both were brutally slow. Thanks

  • intrusive_ptr: Why isn't a common base class provided?

    - by Jon
    intrusive_ptr requires intrusive_ptr_add_ref and intrusive_ptr_release to be defined. Why isn't a base class provided which will do this? There is an example here: http://lists.boost.org/Archives/boost/2004/06/66957.php, but the poster says "I don't necessarily think this is a good idea". Why not?

  • Splitting a list based on another list values in Mathematica

    - by Max
    In Mathematica I have a list of point coordinates size = 50; points = Table[{RandomInteger[{0, size}], RandomInteger[{0, size}]}, {i, 1, n}]; and a list of cluster indices these points belong to clusterIndices = {1, 1, 1, 1, 1, 1, 1, 2, 2, 1, 2, 1, 2, 1, 1, 1, 1, 1, 1, 1}; what is the easiest way to split the points into two separate lists based on the clusterIndices values?

  • Missing Required Gems - javan-whenever and cron job in rails

    - by Matenia Rossides
    Hi, I have finally managed to get javan-whenever gem working on my site5 server, and updating the crontab is quite easy, however whenever a cron job is run with the code that is generated, i get a "missing required gems" error where it lists about 8/10 of my gems. Has anyone else had this problem? If so, what would the solution be. The funny thing is that when it outputs where my gems are, this is all correct, and the gems are loading fine from within my application. Cheers, Matenia

  • Applications of concurrent queues and stacks in .NET 4

    - by Jon Harrop
    .NET 4 includes new concurrent data structures. The Bag and Dictionary collections have obvious applications but I cannot see any use for the Queue and Stack data structures. What are people using these for? Also, I've noticed that the design based upon linked lists incurs a lot of allocation and that destroys scalability. This is surprising given that the sole purpose of these collections is multicore programming. Is this an inherent limitation or are they just badly implemented?

  • writing a shell script if statement to check for directory

    - by user1553248
    I need to write a script that will recreate my opt folder if it gets deleted when I remove a package from it. Here's a link to my previous post: dpkg remove to stop processes Now, the issue I'm running into could be better described here: http://lists.debian.org/debian-devel/2006/03/msg00242.html I was thinking of just adding a postrem script which checks if an opt directory exists, and if not, creates one. My experience with shell scripts is pretty limited though..

  • C Language Standard Collections Where Are They?

    - by flaxeater
    I have committed to learning C now, I'm good with Python/PHP/Bash but I've decided I'm limited by not being fluent in C. However I cannot imagine working in a language without lists and hashes, maybe I'm just jumping a gun, but surely there are 'standard' collection libraries. I do not see any in the GNU standard lib though, any suggestions?

    - by noizetoys
