• UIEvent timestamp

  - by skajam66

  When handling a UIButton touch, you are given a UIEvent object. The UIEvent object has a timestamp which the Apple documentation states as being "the time that the event was created" (UIEvent Class Reference). In the documentation on the Main Event Loop, it states that: "The application object obtains the topmost object in the event queue, converts it to an event object (UIEvent) ..." Does [UIEvent timestamp] refer to the time at which the UIEvent object is created (i.e. after processing the touch event off of the main run loop and hance not remotely real-time) or does it refer to the time that the underlying touch object was created (and hence as close as possible to representing the actual time of the user touch9?

• Maven workspace resolution horked

  - by user237815

  I'm using m2eclipse to manage maven projects. Somehow I did a bad thing, and now the system is behaving as if workspace resolution is disabled. I have several projects that depend on a main project. This project has a version of 4.0-SNAPSHOT, and all the dependent projects reference it in the dependencies section of their poms. Everything was working fine until I created an entirely new project and mistakenly copied the pom from the main project into the new project. Suddenly, all of the dependent projects got the error: "The container 'Maven Dependencies" references non existing library C:\users\myusername.m2\com\mydomain\myproject\4.0-SNAPSHOT\myproject-4.0-SNAPSHOT.jar I zapped the offending new project, but the error remains for all the dependent projects. I've made no changes (to my knowledge) in the main project or any of the dependent projects, so I'm guessing something got changed in the Eclipse environment. Does m2eclipse or Maven itself maintain settings anywhere that I can blow away?

• Bash: Continue script if only one instance is running.

  - by Andrew

  Hello, now this is embarrassing. I'm writing quick script and I can't figure out why this statement don't work. if [ $(pidof -x test.sh | wc -w) -eq 1 ]; then echo Passed; fi I also tried using back-ticks instead of $() but it still wouldn't work. Can you see what is wrong with it? pidof -x test.sh | wc -w returns 1 if I run it inside of script, so I don't see any reason why basically if [ 1 -eq 1 ] wouldn't pass. Thanks a lot!

• nodejs, mongodb - How do I operate on data from multiple queries?

  - by Ryan

  Hi all, I'm new to JS in general, but I am trying to query some data from MongoDB. Basically, my first query retrieves information for the session with the specified session id. The second query does a simple geospacial query for documents with a location near the specified location. I'm using the mongodb-native javascript driver. All of these query methods return their results in callbacks, so they're non-blocking. This is the root of my troubles. What I'm needing to do is retrieve the results of the second query, and create an Array of sessionIds of all the returned documents. Then I'm going to pass those to a function later. But, I can't generate this array and use it anywhere outside the callback. Does anyone have any idea how to properly do this? http://dpaste.org/wXiE/

• What are the semantics of [myThing.myProperty release]?

  - by dugla

  I clearly have not fully grocked properties. I have an instance of a class, myThing. myThing has a property that has be synthesized: // .h @property(nonatomic,retain)MyCoolType *coolType; // .m @synthesize coolType; In my program I call: // The retain count on MyCoolType is 1. [myThing.coolType release]; The reference count on MyCoolType is now zero and dealloc should fire. So, shouldn't myThing.coolType now be nil? In my code that is not the case. How do a correctly release and force the property to return nil? Thanks, Doug

• Retain ViewData when editing variable length list

  - by Pieter

  I'm editing variable length lists and use ViewData to pass around information for filling a DropDownList. I use the method described here for editing these lists: http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/ The data for this dropdownlist comes from the database. As the ViewData is not available across requests, I currently do a new query to the database each and every time. This also happens when the ModelState is not valid and the form is redisplayed. Of course, this is less then ideal even for a light-weight query as this one. How can I retain the information from that query across requests as long as the user is editing the page with that variable length list?

• jQuery - getting the id of the item selected

  - by John Leonard

  I have a basic jQuery selector question. Let's say I'm parsing JSON and generating a row of data for each item in my result set. On each item row, I want an action button. What is the best practice to script that button so its click action can reference the data specific to that row? Starting with the block below, how do I generate a 'Click Me' button that when clicked will alert with its json data? $.getJSON(url,params,function(json){ if(json.items){ $.each(json.items, function(i, n){ var item = json.items[i];

• How do I convert a Python list of lists of lists into a C array by using ctypes?

  - by pc05

  As seen here How do I convert a Python list into a C array by using ctypes? this code will take a python array and transform it to a C array. import ctypes arr = (ctypes.c_int * len(pyarr))(*pyarr) Which would the way of doing the same with a list of lists or a lists of lists of lists? For example, for the following variable list3d = [[[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]], [[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]], [[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]]] I have tried the following with no luck: ([[ctypes.c_double * 4] *2]*3)(*list3d) # *** TypeError: 'list' object is not callable (ctypes.c_double * 4 *2 *3)(*list3d) # *** TypeError: expected c_double_Array_4_Array_2 instance, got list Thank you! EDIT: Just to clarify, I am trying to get one object that contains the whole multidimensional array, not a list of objects. This object's reference will be an input to a C DLL that expects a 3D array.

• How can I set the Rails environment for my somewhat stand alone Ruby script?

  - by Nick

  I have a Ruby script in my Rails app that I use to load some data from Twitter. In the future I will make it an automatic background process, but for now I run it manually like: ruby /lib/twitter/twitterLoad.rb In order to use the Rails model classes and such, I have the following as the top line of the script: require "#{File.dirname(__FILE__)}/../../config/environment.rb" By default, the development environment is used. But, I'd like to be able to choose the production environment at some point. Update #1: The RAILS_ENV constant is getting set in the environment.rb file. So, I was able to put ENV['RAILS_ENV'] = 'production' at the very top (before the environment.rb) line and solve my problem somewhat. So, my new question is, can do pass in env vars through the command line?

• Multiple fields from LINQ to Text Box

  - by Chuki2

  how can I pass value from selected field (LINQ) to textbox in winforms? If single fields, I just do like this var result = from row in dtValueBranch.AsEnumerable() where row.Field<int>("branchID") == idBranch select row.Field<string>("branchName"); StringBuilder sb = new StringBuilder(); foreach (string s in result) { sb.Append(s + Environment.NewLine); } tbBranch.Text = sb.ToString(); So this is the code LINQ to many fields var result = from row in dtValueBranch.AsEnumerable() where row.Field<int>("branchID") == idBranch select new { BranchName = row["branchName"].ToString(), branchTel = row["branchTel1"].ToString(), // And many more fields }; How can I to implement each fields to each textbox?

• SVN Subversion use explicit cached credentials

  - by Nick

  I am trying to run a SVN command in a script, but the script is launched as a system service that has cached svn username/password credentials. I could always just put the username/password arguments in the command: svn info --username bob --password pass but I'd rather not have my username/password just sitting in a text file. I've discovered that my cached credentails (when run svn normally) end up here: C:\Documents and Settings\bob\Application Data\Subversion\auth\svn.simple\6ef188c2163f1ccc860a690b7ad21a15 Is there any way I could copy this cached credential file to where my script exists and just call that file explicitly?

• Force Decimal Regex

  - by babyangel86

  Hi, I'm looking for a regex or a way to format the NumberValidator so that only decimal places are allowed. The domain="real" allows you to put integer values, but I need to force the user to but in 2.0 if they want an integer. This is because they pass through a Castor mapping file, it complains if it gets an integer when it expects a decimal. I dont want to restrict the number of decimal places, just insist that there must be a point, and a number after it. Any help would be much appreciated.

• Split text files Accross threads

  - by Kevin

  The problem: I have a few text files (10) with numbers in them on every line. I need to have them split across some threads I create using the pthread library. these threads that are created (worker threads) are to find the largest prime number that gets sent to them (and over all the largest prime from all of the text files). My current thoughts on solutions: I am thinking myself to have two arrays and all of the text files in one array and the other array will contain a binary file that I can read say 1000 lines and send the pointer to the index of that binary file in a struct that contains the id, file pointer, and file position and let it crank through that. a little bit of what I am talking about pthread_create(&threads[index],NULL,calc_sqrt,(void *)threadFields[index]);//Pass struct to each worker Struct: typedef struct threadFields{ int *id, *position; FILE *Fin; }tField; If anyone has any insight or a better solution it would be greatly appreciated Thanks

• Why my WCF Service returns xml serialized objects?

  - by user294554

  Hi, I'm new here and I hope anyonte can help me. I have WCF Service and Windows Forms working with this client written in VB.NET. The Service class started to return xml serialized objects, but all my classes on Service side are DataContract-s and the service class is DataContractFormat. I googled everywhere about serializations and I couldn't find reason why it started to do that. I checked my classes and service, app.config file, but I couldn't find anything. I checked Reference.vb class, and it's System.Xml.Serialization.XmlElementAttribute everywhere. The question may seem dummy, but I really don't know what to do. I just want to know what can cause the service to act like that. Thank you.

  I'm trying to learn a bit of LINQ but I'm having compile issues right off the bat. Is there any specific reason why this won't work? using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace HelloLINQ { class HelloLINQ { public static void Main() { Example1(); } public static void Example1() { var numbers = new int[] { 1, 5, 3, 7, 3, 8, 9, 3, 6, 6, 2 }; var under5 = from n in numbers select n; foreach (var n in under5) { Console.WriteLine(n); } } } } The error is: Could not find an implementation of the query pattern for source type 'int[]'. 'Select' not found. Are you missing a reference to 'System.Core.dll' or a using directive for 'System.Linq'?

• Give users permissions on item in other list

  - by Nomz

  Hello everyone, This is what im working on: i have two lists, first one: collumn user and collumn project that the user is assigend to. second one (library): a list of all the projects I was wondering, how, by every row that is created in the first list (so adding a user and a project) it is possible to grant the user permissions on this project's reference in the second library (the projects library). Example: ProjectLibrary: Project1 Project2 Project3 the first list: user1 project1 user1 project2 user2 project2 user2 project3 user3 project3 now i want to give each user permission to see the project he's assigned to so that when he opens a third form, a combobox filled with projects will only show the projects he has permissions on. thank you so much!

• [CSS] style input tag

  - by nosferat

  Hi! ASP.Net has a tag called CheckboxList. The output of this tag looks like this: <table class="checkbox"> <tbody> <tr> <td> <input id="/*longdynamicstring1*/" type="checkbox" name="/*longdynamicstring2*/" /> <label for="/*longdynamicstring1*/">Label Text</label> </td> </tr> </tbody> </table> I want to position the label and the input but I cannot find out how. Tried the following: .checkbox input{ padding-right: 5px; } and .checkbox input[type='checkbox'] { padding-right: 5px; } but neither of them had any effect. Because it's ASP I cannot set a class for the input elements and I cannot reference the id because it's dynamic.

• Google App Engine - Is os.environ reset between requests?

  - by Ian Charnas

  Hello I can't think of a way to test this and was hoping someone here knew the answer... I'm storing some request-specific data in os.environ, and was wondering if that data was going to leak to other requests. Does anyone know? Yes I realize that it's normal to use request.environ for this, and usually I do, but I want to store the currently authorized user ID (I'm using custom auth, not GAE auth) inside os.environ so that the models know the currently logged in user (remember, they don't have access to request.environ) without me having to pass the request object to just about every single model method. any help would be greatly appreciated Ian

• javascript window.close, once again

  - by John Kjøller

  Im sorry if I havent done my research properly, - but couldnt find the answer I needed, so here goes: From my main page I open a new window using mainPlayer = window.open(); This window stays open until user clicks on a mainPlayer.close(); event. (or simply x closes the window) However, the idea is to make it possible to let the player keep playing, while browsing around the rest of the pages. But as soon as the user leaves the page that opened the mainPlayer window, the reference to the mainPlayer window seem to be lost. How do I, from the site's other pages, check if the mainPlayer window is open and close it on a click event? Thx John
