  • Default Sorting in DynamicData

    - by Jens A.
    I am using DynamicData in the version that shipped with VS2008. In the default List view, the data is sorted by order of entry into the database. I'd like to get it sorted by a field of a specific name (descending). As a last resort I tried to use the OrderByParameter of the LinqDataSource with a QueryStringParameter, but I could not get it to sort anything. =) Is there an easy way to accomplish this?

  • Which relational databases exist with a public API for a high level language?

    - by Jens Schauder
    We typically interface with a RDBMS through SQL. I.e. we create a sql string and send it to the server through JDBC or ODBC or something similar. Are there any RDBMS that allow direct interfacing with the database engine through some API in Java, C#, C or similar? I would expect an API that allows constructs like this (in some arbitrary pseudo code): Iterator iter = engine.getIndex("myIndex").getReferencesForValue("23"); for (Reference ref: iter){ Row row = engine.getTable("mytable").getRow(ref); } I guess something like this is hidden somewhere in (and available from) open source databases, but I am looking for something that is officially supported as a public API, so one finds at least a note in the release notes, when it changes. In order to make this a question that actually has a 'best' answer: I prefer languages in the order given above and I will prefer mature APIs over prototypes and research work, although these are welcome as well.

  • In LaTeX, is there a way to get long lines along the margins?

    - by Christian Jonassen
    I'm working on a report, and some elements are outside the margins (but some are just barely outside the margins). I was wondering: Is there a way to make two vertical lines, one on each side, along the margins so that one can easily see if it goes outside them? (Googling it, I only found information about margin notes.) A figure is below: |report text goes here| |more text goes also h|ere |and so on and so fort|h It would certainly make correcting these kinds of mistakes very trivial. :) Feel free to post answers that would solve/show this problem in a more "LaTeX-correct" way, if that makes any sense at all.

  • Setting 0 margin in header using LaTeX's fancyhdr

    - by Morten
    Hi, I'm trying to define a custom layout for my report for which I'm using fancyhdr. On the pages which contains a chapter start I want my header to contain a colorbox spanning across the whole page (0 cm margins) although keeping my defaults margin in the text area. I can get the box to span across the "margin notes" area, but not the other side. Here's some of my code: \fancypagestyle{plain}{ % pages containing chapter start \fancyhead{} \fancyhead[RO]{\colorbox{NavyBlue}{\textcolor{White}{\raisebox{0cm}[1cm][0.5cm]{\makebox[3cm][c]{\textbf{\CNoV\thechapter}}}}} } Any ideas on how to do it?

    - by jpallavi
    1)Url field should also accept url as “www.abc.com”. If user enters url like this, it should be automatically appended with “http://” resulting in value saved in database as “http://www.abc.com”.

  • Registration with profile picture using services in Drupal

    - by Fran Ruano
    I've been trying to upload a user profile picture during the user registration using Service 3 and so far I haven't had any luck. I tested passing a hard coded fid in the field "picture" and also tried to pass the fields "filemime", "filename", etc. and it didn't work neither. Any idea about what fields I need to populate? I guess it must be related to this post Using Drupal Services and DIOS SDK for setting user picture in iOS app but it doesn't have and answer neither.

    My nested resources are working for form_for updates, but I have a few toggles that I need to setup to change a status field.

  • Beginning with Datampper, Association question

    - by Ian
    I'm just diving into Datamapper (and Sinatra) and have a question about associations. Below are some models I have. This is what I want to implemented. I'm having an issue with Workoutitems and Workout. Workout will be managed separately, but Workoutitems has a single workout associated with each row. Workout - just a list of types of workouts (run, lift, situps, etc) Selected workout - this is the name of a set of workouts, along with notes by the user and trainer. It has a collection of N workoutitems Workoutitems - this takes a workout and a number of repetitions to it that go in the workout set. class Workout include DataMapper::Resource property :id, Serial #PK id property :name, String, :length=50,:required=true # workout name property :description, String, :length=255 #workout description end class Selectedworkout include DataMapper::Resource property :id, Serial property :name, String, :length=50, :required=true property :workout_time, String, :length=20 property :user_notes, String, :length=255 property :coach_notes, String, :length=255 has n, :workoutitems end class Workoutitem include DataMapper::Resource property :id, Serial property :reps, String, :length=50, :required=true belongs_to :selectedworkout end

  • Zend Framework AjaxContext filters the results and Decorators not removable

    - by Janis Peisenieks
    Ok, since this problem has 2 parts, it will be easier to explain them together. So here goes: I am trying to remove the default decorators from these elements, since I am using a little different way of styling them. But no matter what i do, the DtDDWrapper still shows up. If I try to remove all of the decorators, all of the fields below disappear. public function newfieldAction() { $ajaxContext = $this->_helper->getHelper('AjaxContext'); $ajaxContext->addActionContext('newfield', 'html')->initContext(); $id = $this->_getParam('id', null); $id1=$id+1; $id2=$id+2; $element = new Zend_Form_Element_Text("newTitle$id1"); $element->setOptions(array('escape'=>false)); $element->setRequired(true)->setLabel('Vertiba')->removeDecorator('label'); $tinyelement=new Zend_Form_Element_Text("newName$id"); $tinyelement->setRequired(true)->setOptions(array('escape'=>false))->setLabel('Vertiba')->removeDecorator('label'); $textarea_element = new Zend_Form_Element_Textarea("newText$id2"); $textarea_element->setRequired(true)->setOptions(array('escape'=>false))->setLabel('Vertiba')->removeDecorator('label'); $this->view->descriptionField = "<td>".$textarea_element->__toString()."</td>"; $this->view->titleField = $element->__toString(); $this->view->field = $tinyelement->__toString(); $this->view->id=$id; } The context view script seams to trim my code in one way or another. When I try to put a <td> or a <table> tag in the view script, it just skips the tags. Is there a way to stop this escaping from happening? My view script: id; ?" asdfasdfasdfasd field ? titleField ? descriptionField ? id ?"remove P.S. the code formatting system is barfing at me, could someone please help me with the formatting of the code?
