• International Assist on iPhone

  - by john-gosset

  Does anyone know if the International Assist feature on the iPhone works when dialing a number using the tel:// URL scheme from an application? For those unfamiliar, IA automatically prefixes the "+1" to US numbers when using the iPhone internationally. I know that this works when dialing from either the built-in Contacts or Phone apps, but can't find anything stating that it works when dialing numbers from an application. Also, is there any documentation as to whether this feature is included on Canadian (Rogers) or European iPhones (or is it only used by AT&T)? If IA does not work when dialing with a custom app, can someone point to the API that would allow me to detect that the use is roaming on a foreign network so I can essentially duplicate IA's functionality? Any help greatly appreciated!

• Attching a Behaviour to a dynamically created table in Doctrine

  - by Cesare Contini

  How do I programmatically attach a Doctrine Behaviour programmatically to a table dynamically created through $conn->export->createTable('MyTable', $definition)? For example, if I have the following code: $definition = array( 'id' => array( 'type' => 'integer', 'primary' => true, 'autoincrement' => true ), 'name' => array( 'type' => 'string', 'length' => 255 ) ); $conn->export->createTable('MyTable', $definition) ; At this point I would need to attach a doctrine typical behaviour like Timestampable or Versionable to the newly created 'MyTable' table. Is it possible at all?

• Rspec-rails doesn't seem to find my models

  - by sa125

  Hi - I'm trying out rspec, and immediately hit a wall when it doesn't seem to load db records I know exist. Here's my fairly simple spec (no tests yet). require File.expand_path(File.dirname(__FILE__) + '../spec_helper') describe SomeModel do before :each do @user1 = User.find(1) @user2 = User.find(2) end it "should do something fancy" end I get an ActiveRecord::RecordNotFound exception, saying it couldn't find User w/ ID=1 or ID=2, which I know for a fact exist. I set both test and development databases to point to the same schema in database.yml, so this shouldn't be database mixup. I also ran script/generate rspec after installing the gems (rspec, rspec-rails), and gem.config both environment.rb and test.rb. Any idea what I'm missing? thanks. EDIT Seems I was running the tests with rake spec:models, which emptied the db and thus no records were found. When I used % spec spec/models/some_model_spec.rb, everything worked as expected.

• How to fix weird scrolling/alignment behavior when using keyboard in MenuStrip?

  - by bentsai

  I started noticing strange behavior when navigating the main toolbar of my Winforms application, and I don't know how to fix it. When I initially open the dropdown of the File menu, it looks like this: I begin to scroll down each item with the arrow keys, and everything is fine until I reach "Exit". As soon as I hit the down arrow key from "Log Off", or if I hit the up arrow key from "Open", the menu rearranges itself to look like this: I'm puzzled by this behavior. The menu still works, and from this point, if I start scrolling up, I can get the arrangement back to normal: A few observations: The menu still works. This doesn't happen when using the mouse. I have some code that toggles the Visible property of some of the menu items. I was able to modify what the arrangement was by playing around with this, but it was still messed up. Can anyone help me understand what is going on, and how to fix it?

• Java book for programmer with intermediate experience

  - by Anthony Forloney

  I am well aware of this previous question here and have heard great things about those books. I actually bought two of them, Effective Java and Java in a Nutshell as an early Christmas present. I am looking for a good Java book, or books, to further continue my understanding of Java from a recent college graduate point of view. I have learned Java in college and would consider it to be the language I am most comfortable with. Can anyone recommend a good "intermediate" Java book for a situation like mine? This question should be community, I just don't know how to migrate it. I apologize for any inconvenience. Thank you in advance.

• Create and access folder outside Apache Tomcat webapps folder

  - by Padur

  My web application requires functionality where end users can upload content, that can be later downloaded or viewed by others, the problem with current scheme is If I create such folder as part of your web project under webapps, every time I do deploy your web application (*.war), the content of that directory will be lost (or overridden). I think the best way to accomplish that is to create folder outside of standard tomcat webapps and access it from there, not sure how to do. Please point in correct direction. I am using Tomcat 4.x soon will be moving to 6.x. -Padur

• How to be sure that my MVC project is runting on the correct version after upgrade to vs2010?

  - by Stephane

  I just installed visual studio 2010 and upgraded my MVC project (which was running on MVC RC2 in visual studio 2008). visual studio 2010 updated every project file to target the framework 4.0. But the system.web.dll is pointing to C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 2\Assemblies\System.Web.Mvc.dll in VS2010 object browser, I have every dll showing up in multiple versions as expected (3.5.0.0 and 4.0.0.0) except for the System.Web.Mvc dll which doesn't show any version and points to the path I mentioned above. Isn't this namespace point to the Framework folder like the System.Web namespace? C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Web.dll

• MVC Site - Ensuring the default entry view is always correct

  - by Klaptrap

  I have a MVC site with AD authorization. This is all working fine. I publish the site to the webserver and call the site directly (http://intranet). If I have not logged in for a while (I have an authorised cookie with a 30 minute TTL), I am prompted to log-in and if successful I am redirected to the homeController's index view. This is great and as expected. If I keep the session open (browser open) and browse away from the site, if I then browse back to http://intranet, I am not challenged as I have recently authenticated but the default page is from a different controller and not the home page view. How can I stop this from happening? It cannot be a session setting as this is not a new session and the routes appear correct - they are not beng called at this point anyhow. Please MVC guru's advise....!

• Updating the datalist in a RadComboBox

  - by jphenow

  So I'm just struggling with a lot of little things in the web app so I'm checking up with all kinds of stuff to make sure i'm not breaking it cause of stupid problems. At some point in my web app (trying to keep it mostly Asynchronous) I have to update the list in my RadComboBox because something was added. Do I just need to call RadComboBox.DataBind() again? Since I don't explicitly use its datasource(I do it in the manual insert using a string fashion) object to insert my new record do I need to tell that to update? The list just doesn't seem to update when i just call databind so I feel like i need to have the datasource recheck for entries or SOMETHING Thanks

• Creating a multiplayer card game

  - by Vikram.exe

  Hi, I was trying to make a multiplayer card game. I know networking concepts, so I know how to handle data between successive turns. I Haven't done a similar thing before so if any one could point me to a tutorial, that would be nice. I am comfortable with html/php/javascript and a bit of adobe flash. Please suggest are these sufficient to create a game or should I go for some other language(s)? Which are the best languages that are currently used to create such multiplayer games? Thanks, Vikram

• Help with ActiveX Install? Merge Modules - Windows Vista and Windows 7

  - by Watts

  I'm building an ActiveX control installer in VS2008 which uses both the CRT and MFC merge modules to install. When my control tries to register on Windows 7 it fails. Dependency Walker says I'm missing the mfc90u.dll, msvcr90.dll and msvcp90.dll dependencies when trying to register my control and the install fails. Are the merge modules supposed to take care of this? My output OCX is being registered with the vsdrpCOMSelfReg option. From what I am reading on other forums, this might not be the best method, what should I try at this point? Install works fine on Windows XP.

• formula for best approximation for center of 2D rotation with small angles

  - by RocketSurgeon

  This is not a homework. I am asking to see if problem is classical (trivial) or non-trivial. It looks simple on a surface, and I hope it is truly a simple problem. Have N points (N = 2) with coordinates Xn, Yn on a surface of 2D solid body. Solid body has some small rotation (below Pi/180) combined with small shifts (below 1% of distance between any 2 points of N). Possibly some small deformation too (<<0.001%) Same N points have new coordinates named XXn, YYn Calculate with best approximation the location of center of rotation as point C with coordinates XXX, YYY. Thank you

• Implementing fallback from Google AJAX Libraries API to local jQuery

  - by Maxim Z.

  After looking up the advantages and disadvantages of using Google's AJAX Libraries API instead of using jQuery locally, I saw that someone wrote in an answer (here on Stack Overflow, of course) that it's possible to get around the downtime that Google's API sometimes experiences by somehow falling back to a local copy of the library you use. I want to use Google's AJAX Libraries API on my site, but I'm concerned about this possible downtime and I'm curious how such a fallback procedure can be implemented. Has anybody ever tried doing this? Can you point me towards some code that accomplishes such a feat? Thanks in advance.

• Unable to view values of variables while debugging

  - by RexM

  I'm trying to debug portions of the current application I'm working on, however when I try and check the value of a property/variable I get the error: Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized. This is just a regular ASP.NET project. In some portions of the application I can view the properties and variables perfectly fine. I haven't figured out what's different about the blocks of code that I can and can not see the values of the variables in.

• Is it good or bad practice to use var everywhere? [closed]

  - by Earlz

  Possible Duplicate: Use of var keyword in C# Hello, I've recently been discovering the awesomeness that is the var keyword in C#. Well, I didn't think about it before but I just wrote lines of code that are along the lines of var con=CreateNewConnection(); Where this would usually be IdbConnection con=CreateNewConnection(); Is this a good use of var? Is it possible to use var too often? Are there any downsides to using it? Also, one more point of consideration: We are not worried about backwards compatability. We just care that it runs on .NET 3.5

• How to properly name record creation(insertion) datetime field ?

  - by alpav

  If I create a table with datetime default getdate() field that is intended to keep date&time of record insertion, which name is better to use for that field ? I like to use Created and I've seen people use DateCreated or CreateDate. Other possible candidates that I can think of are: CreatedDate, CreateTime, TimeCreated, CreateDateTime, DateTimeCreated, RecordCreated, Inserted, InsertedDate, ... From my point of view anything with Date inside name looks bad because it can be confused with date part in case if I have 2 fields: CreateDate,CreateTime, so I wonder if there are any specific recommendations/standards in that area based on real reasons, not just style, mood or consistency. Of course, if there are 100 existing tables and this is table 101 then I would use same naming convention as used in those 100 tables for the sake of consistency, but this question is about first table in first database in first server in first application.

• How can I read a textfile into matlab and make it a list?

  - by Ben Fossen

  I have a textfile that has the format gene complement(22995..24539) /gene="ppp" /locus_tag="MRA_0020" CDS complement(22995..24539) /gene="ppp" /locus_tag="MRA_0020" /codon_start=1 /transl_table=11 /product="putative serine/threonine phosphatase Ppp" /protein_id="ABQ71738.1" /db_xref="GI:148503929" gene complement(24628..25095) /locus_tag="MRA_0021" CDS complement(24628..25095) /locus_tag="MRA_0021" /codon_start=1 /transl_table=11 /product="hypothetical protein" /protein_id="ABQ71739.1" /db_xref="GI:148503930" gene complement(25219..26802) /locus_tag="MRA_0022" CDS complement(25219..26802) /locus_tag="MRA_0022" /codon_start=1 /transl_table=11 /product="hypothetical protein" /protein_id="ABQ71740.1" /db_xref="GI:148503931" I would like to read the textfile into Matlab and make a list with the information from the line gene as the starting point for each item in the list. So for this example there will be 3 items in the list. I have tried a few things and cannot get this to work. Anyone have any ideas of what I can do?

• accepts_nested_attributes_for and has_many :through relations.

  - by antiarchitect

  I want to make a simple examing application on RoR 2.3. The problem area is to make an exam_session in a one form with only one submit action. For the exam session there are selected some number of questions from the question pool in random order. For these questions there are selected some number of alternatives (to check is this a single answer question or multi answer question I use the number of correct alternatives: if only 1 - single, 1 - multi. Radiobuttons or checkboxes in form to answer depends on it). I have models: Questions ---< Alternative and ExamSession. I think there must be has_many :through relations between ExamSession and Questions and has_many :through relation between the intermediate table (for example QuestionsExamSession) and Alternative to point what alternatives are answers of the student on this Question. So the questions are: Is this scheme is too complicated and there is a way to do it simple and clear? Is there any way to organize models in such a way to make the form I want to work?

• Which OOD approach should I take?

  - by Sorush Rabiee

  According to Niklaus Wirth, Algorithms + Data Structures = Programs. So I use this as a start point to object-oriented modeling and inheritance design: in a way that I separate the 'Objects' from 'Operations'. then look for patterns and inheritance hierarchy. But now after practice I guess it's not a good idea for every modeling problem, because sometimes it's not effective. (I mean there is no possibility of developing (or is very hard to develop) codes of Turing-Completed languages based on this paradigm.) What is your viewpoint for designing an OOD structure as an experienced programmer?

• Coding guidelines + Best Practices?

  - by Chathuranga Chandrasekara

  I couldn't find any question that directly applies to my query so I am posting this as a new question. If there is any existing discussion that may help me, please point it out and close the question. Question: I am going to do a presentation on C# coding guidelines but it is not supposed to limit to coding standards. So I have a rough idea but I think I need to address good programing practices. So the contents will be something like this. Basic coding standards - Casing, Formatting etc. Good practices - Usage of Hashset over other data structures, String vs String Builder, String's immutability and using them effectively etc Really I would like to add more good practices (Especially to improve the performance.) So like to hear some more good practices to be used with C#. Any suggestions??? (No need of large descriptions :) Just the idea is sufficient.)

• How to run script from command-line

  - by Eric

  I want to write a script that counts the types of objects there are in the ZODB, when they were created, how many users have joined since a given point in time,etc. I am wondering how to accomplish this. So, was wondering if there is a way to pass a script to bin/instance to be executed. I've created this script with a py script but it takes a VERY long time to finish and this is why I would like to do this from the command-line... in the hopes of it running faster. Thanks ERic

• fast algorithm implementation to sort very small set

  - by aaa

  hello. This is the problem I ran into long time ago. I thought I may ask your for your ideas. assume I have very small set of numbers (integers), 4 or 8 elements, that need to be sorted, fast. what would be the best approach/algorithm? my approach was to use the max/min functions. I guess my question pertains more to implementation, rather than type of algorithm. At this point it becomes somewhat hardware dependent , so let us assume Intel 64-bit processor with SSE3 . Thanks

• Dynamically creating a TreeViewin HTML with indent lines in ASP.NET

  Hi, i'm quite new to HTML, and am trying to create a professional looking TreeView. I can not use the in built TreeView in ASP.NET as i need to point the target of the selection to another frame (I have tried, and this doesn't seem possible). My TreeView is built up as follows: Folder1 ChildOne ChildTwo ChildThree Folder2 ChildOne ChildTwo ChildThree I have the collapsing of the folders working, but would like to know how to format this TreeView so it has dotted lines down to the child nodes (as most TreeViews tend to have). How would i go about this? Cheers.
