  • WPF, Setting property with single value on multiple subcontrols

    - by Andre van Heerwaarde
    I have a parent contentcontrol which displays data via a datatemplate. The datatemplate contains a stackpanel with several usercontols of the same type. I like to set the property only once on the parent control, it must set the value of the property on all the subcontrols. But if there is a way to do it on the stackpanel it's also OK. The template can be changed at runtime and the values need also to be propagated to the new template. My current solution is to implement the property on both parent and subcontrol and use code to propagate the value from the parent to all the subcontrols. My question is: is there a better or other ways of doing this?

  • How to have multiple paths display URL as root

    - by Verdi Erel Ergün
    I want users#new and tasks#index to display as the root path URL, i.e. / When a user logs in on the path users#new (set as root) they are redirected to tasks#index and URL does not change. Can this be done in the routes.rb file? This is my routes.rb file: Todo::Application.routes.draw do resources :sessions resources :subscriptions resources :users resources :tasks do collection do post :sort end end root :to => "users#new" match "sessions#new" => "tasks#index" match "sessions#" => "tasks#index"

  • How to run setInterval() on multiple canvases simultaneously?

    - by Alex
    I have a page which has several <canvas> elements. I am passing the canvas ID and an array of data to a function which then grabs the canvas info and passes the data onto a draw() function which in turn processes the given data and draws the results onto the canvas. So far, so good. Example data arrays; $(function() { setup($("#canvas-1"), [[110,110,100], [180,180,50], [220,280,80]]); setup($("#canvas-2"), [[110,110,100], [180,180,50], [220,280,80]]); }); setup function; function setup(canvas, data) { ctx = canvas[0].getContext('2d'); var i = data.length; var dimensions = { w : canvas.innerWidth(), h : canvas.innerHeight() }; draw(dimensions, data, i); } This works perfectly. draw() runs and each canvas is populated. However - I need to animate the canvas. As soon as I replace line 8 of the above example; draw(dimensions, data, i); with setInterval( function() { draw(dimensions, data, i); }, 33 ); It stops working and only draws the last canvas (with the others remaining blank). I'm new to both javascript and canvas so sorry if this is an obvious one, still feeling my way around. Guidance in the right direction much appreciated! Thanks.

  • Supervising multiple gen_servers with same module / different arguments

    - by Justin
    Hi, I have a OTP application comprising a single supervisor supervising a small number of gen_servers. A typical child specification is as follows: {my_server, {my_server, start_link, [123]}, permanent, 5000, worker, [my_server]} No problems so far. I now want to an add extra gen_server to the supervisor structure, using the same module Module/Fn as above, but different arguments, eg {my_server_2, {my_server, start_link, [123]}, permanent, 5000, worker, [my_server_2]} I thought this would work, but no: =SUPERVISOR REPORT==== 15-Apr-2010::16:50:13 === Supervisor: {local,my_sup} Context: start_error Reason: {already_started,<0.179.0>} Offender: [{pid,undefined}, {name,my_server_2}, {mfa,{my_server,start_link,[]}}, {restart_type,permanent}, {shutdown,5000}, {child_type,worker}] Do the module arguments in the second element of each child specification need to be different ? Thanks, Justin

  • Rails Model multiple column uniqueness

    - by Jty.tan
    I am making a Viewer model with belongs_to :users belongs_to :orders that joins the models Users and Orders with a :has_many :through => :viewers. And the Viewer model has the attributes of user_id and order_id. How would I set it up so that new viewers are only accepted if both user_id and order_id are unique in the same row? I remember in MySQL being able to do so with a flag (although I can't for the life of me remember what it was), but I'm not sure how to do it with Rails. Can I do something like (for Viewer.rb) validates_uniqueness_of :user_id, :scope => :order_id?

  • Spring aop multiple pointcuts & advice but only the last one is working

    - by Jarle Hansen
    I have created two Spring AOP pointcuts that are completely separate and will be woven in for different parts of the system. The pointcuts are used in two different around advices, these around-advices will point to the same Java method. How the xml-file looks: <aop:config> <aop:pointcut expression="execution(......)" id="pointcutOne" /> <aop:pointcut expression="execution(.....)" id="pointcurTwo" /> <aop:aspect id="..." ref="springBean"> <aop:around pointcut-ref="pointcutOne" method="commonMethod" /> <aop:aroung pointcut-ref="pointcutTwo" method="commonMethod" /> </aop:aspect> </aop:config> The problem is that only the last pointcut works (if I change the order "pointcutOne" works because it is last). I have gotten it to work by creating one big pointcut, but I would like to have them separate. Any suggestions to why only one of the pointcuts works at a time?

  • How do I do multiple assignment in MATLAB?

    - by Benjamin Oakes
    Here's an example of what I'm looking for: >> foo = [88, 12]; >> [x, y] = foo; I'd expect something like this afterwards: >> x x = 88 >> y y = 12 But instead I get errors like: ??? Too many output arguments. I thought deal() might do it, but it seems to only work on cells. >> [x, y] = deal(foo{:}); ??? Cell contents reference from a non-cell array object. How do I solve my problem? Must I constantly index by 1 and 2 if I want to deal with them separately?

  • Multiple delimiters using Regex.Split in C#

    - by Arthur Frankel
    Let's say you need to split a string by various delimiters including newline (/r, /n) and a few other 'special' character strings. For example: This is a sample %%% text &&& that I would like to split %%% into an array. I would like the following in the resulting string array (contents via index) [0]This is a sample [1]text [2]that I would [3]like to split [4]into an array. I would like to use C# Regex.Split() function. What is the regex expression to match on all of my delimiters? Thanks in advance

  • How to use google maps API with multiple markers on the same map

    - by Maen
    So, i have the following script to use the google maps API, its all fine, but i need to create a map that has more than one Marker (the balloon shaped icon pointing to something) and i need each of those markers to point on a different area of the map (i.e. different coordinates), how can i do it? <script type="text/javascript"> function load() { var map = new GMap2(document.getElementById("map")); var marker = new GMarker(new GLatLng(<%=coordinates%>)); var html="<img src='simplemap_logo.jpg' width='20' height='20'/> " + "<%=maptitle%><br/>" + "<%=text%>"; map.setCenter(new GLatLng(<%=coordinates%>), <%=zoom%>) map.setMapType(G_HYBRID_MAP); map.addOverlay(marker); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); marker.openInfoWindowHtml(html); } //]]> </script> One more question, if i pass the Script text as a variable, lets say something like: <script type="text/javascript"> <%=ScriptText%> </script> and my <%=ScriptText% will be a string which i will build and assign its value to a Friend or Public variable called ScriptText, will it still run and work properly? (i am doing this to make my script dynamic and different based on how i build it as a STRING, due to my illiteracy in javascripting ;P)

  • Acts as Tree with Multiple Models

    - by Joe
    I've got several models that I'd like to relate together hierarchically. For simplicity's sake, let's say I've got these three: class Group < ActiveRecord::Base acts_as_tree has_many :users end class User < ActiveRecord::Base acts_as_tree belongs_to :group has_many :posts end class Post < ActiveRecord::Base acts_as_tree belongs_to :user end Under the current acts_as_tree, each node can individually can relate hierarchically to other nodes provided they are of the same type. What I'd like is to remove this restriction on type identity, so that SomePost.parent could have a User or a Post as its' parent, and that SomeUser.parent could have another user or a group as its parent. Any thoughts?

  • .htaccess Redirect Loop, adding multiple .php extensions

    - by Ryan Smith
    I have sort of a small parent/teacher social network set up for my school. I use my .htaccess file to make the links to teacher profiles cleaner and to add a trailing slash to all urls. I get this problem when going to /teachers/teacher-name/ the link (sometimes) redirects to /teachers/teacher-name.php.php.php.php.php.php.php.php... Below is my .htaccess file. Sometimes if I clear my browser cache in Chrome it temporarily fixes it. I can't exactly wright .htaccess syntax, but I'm pretty familiar with it. Any suggestions are appreciated!

  • multiple classes with same methods - best pattern

    - by Tony
    I have a few classes in my current project where validation of Email/Website addresses is necessary. The methods to do that are all the same. I wondered what's the best way to implement this, so I don't need to have these methods copy pasted everywhere? The classes themselves are not necessarily related, they only have those validation methods in common.

  • A better way to delete a list of elements from multiple tables

    - by manyxcxi
    I know this looks like a 'please write the code' request, but some basic pointer/principles for doing this the right way should be enough to get me going. I have the following stored procedure: CREATE PROCEDURE `TAA`.`runClean` (IN idlist varchar(1000)) BEGIN DECLARE EXIT HANDLER FOR NOT FOUND ROLLBACK; DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK; DECLARE EXIT HANDLER FOR SQLWARNING ROLLBACK; START TRANSACTION; DELETE FROM RunningReports WHERE run_id IN (idlist); DELETE FROM TMD_INDATA_INVOICE WHERE run_id IN (idlist); DELETE FROM TMD_INDATA_LINE WHERE run_id IN (idlist); DELETE FROM TMD_OUTDATA_INVOICE WHERE run_id IN (idlist); DELETE FROM TMD_OUTDATA_LINE WHERE run_id IN (idlist); DELETE FROM TMD_TEST WHERE run_id IN (idlist); DELETE FROM RunHistory WHERE id IN (idlist); COMMIT; END $$ It is called by a PHP script to clean out old run history. It is not particularly efficient as you can see and I would like to speed it up. The PHP script gathers the ids to remove from the tables with the following query: $query = "SELECT id, stop_time FROM RunHistory WHERE config_id = $configId AND save = 0 AND NOT(stop_time IS NULL) ORDER BY stop_time"; It keeps the last five run entries and deletes all the rest. So using this query to bring back all the IDs, it determines which ones to delete and keeps the 'newest' five. After gathering the IDs it sends them to the stored procedure to remove them from the associated tables. I'm not very good with SQL, but I ASSUME that using an IN statement and not joining these tables together is probably the least efficient way I can do this, but I don't know enough to ask anything but "how do I do this better?" If possible, I would like to do this all in my stored procedure using a query to gather all the IDs except for the five 'newest', then delete them. Another twist, run entries can be marked save (save = 1) and should not be deleted. The RunHistory table looks like this: CREATE TABLE `TAA`.`RunHistory` ( `id` int(11) NOT NULL auto_increment, `start_time` datetime default NULL, `stop_time` datetime default NULL, `config_id` int(11) NOT NULL, [...] `save` tinyint(1) NOT NULL default '0', PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8;
