  • HttpsURLConnection failing intermittently to the same URL

    - by Arkaitz Jimenez
    I think I'm experiencing the same as http://groups.google.com/group/android-developers/msg/9d37d64aad0ee357 This is Android 1.5 SDK. I happen to call several times below code(which is in a method) with the same url and it fails intermittently. When it fails, there is no exception, the stream is empty so the readConnection fails, and getResponseCode returns -1. Global caching is disabled, setDefaultUseCaches(false); I suppose there must be some kind of url connection object pool somewhere. Any idea on how can I workaround this? HttpURLConnection connection = null; try { URL url = new URL(this.url); connection = (HttpURLConnection) url.openConnection(); connection.setRequestProperty("Authorization", "basic " + Base64Coder.encodeString(user + ":" + password)); connection.setRequestProperty("User-Agent", userAgent); connection.connect(); readConnection(connection.getInputStream()); connection.disconnect(); } catch (IOException ex) { reportException(ex, connection.getResponseCode()) } catch (ParserException ex) { reportException(ex, connection.getResponseCode()) }

  • Using Linq on a Dataset

    - by JasonMHirst
    Can someone enlighthen me with regards to Linq please? I have a dataset that is populated via a SQL Stored Procedure, the format of which is below: Country | Brand | Variant | 2004 | 2005 | 2006 | 2007 | 2008 The number of rows varies between 50 and several thousand. What I'm trying to do is use Linq to interrogate the dataset (there will be several Linq queries based on user options), but a simple example would be to SUM the year columns based on Brand. I have the following that I believe creates a template for me to work with: But from here on I'm absolutely stuck! sqlDA.Fill(ds, "Profiler") Dim brandsQuery = From cust In ds.Tables(0).AsEnumerable() Select _BrandName = cust.Item("BrandName"), _y0 = cust.Item("1999"), _y1 = cust.Item("2004"), _y2 = cust.Item("2005"), _y3 = cust.Item("2006"), _y4 = cust.Item("2007"), _y5 = cust.Item("2008") I'm tried to look at examples, but can't see any that are VB.Net based and/or show me how to Sum/Group. Can someone please provide an example so I can perhaps learn from it. Thanks.

  • What are you using for Web UI/layout design?

    - by brendan
    What are folks out there using for web/ui design? For the most part we use PowerPoint at my company. The UI folks will mock up a screen in PowerPoint and we (the development group) will take it from there. So, for a side gig of mine I decided to do some mock ups to show the client prior to dev and I'm quickly feeling that PowerPoint is not the right tool for this. What are you using for this type of stuff - some other software? pen/paper?

  • Creating Thumbnails in Build Phase of iPhone App Xcode project?

    - by nephilite
    Hey All, I have a group of png files in my bundle; but I also want smaller versions of them to be used at my app as well. Right now I am just resizing them all manually and putting them in the bundle as well: so i might have Graphic_1.png and Graphic_1-thumbnail.png. Instead, is there anyway to do something like: at build time, take all my png assets and create 1/4 scale versions of them, and save them into the bundle as well, with the -thumbnail in the filename as above? Thanks!

  • penetration of web 2.0 features amongst users?

    - by user151841
    I have a survey web-app that is public facing. I want to set up automated testing with Selenium, but selenium can't capture javascript alerts that we're currently using on the site. I'm thinking about changing our user-facing error notifications to some web 2.0 javascript library so that it is accessible to Selenium. However, I'm not sure how many of our users would be able to experience them properly. How backwards-compatible do I need to be in the present day? I have collected a database of actual user-agent strings of our users. I asked here how I could group them into meaningful data about what browsers our users are actually using.

  • Fill data gaps - UNION, PARTITION BY, or JOIN?

    - by Dave Jarvis
    Problem There are data gaps that need to be filled. Would like to avoid UNION or PARTITION BY if possible. Query Statement The select statement reads as follows: SELECT count( r.incident_id ) AS incident_tally, r.severity_cd, r.incident_typ_cd FROM report_vw r GROUP BY r.severity_cd, r.incident_typ_cd ORDER BY r.severity_cd, r.incident_typ_cd Data Sources The severity codes and incident type codes are from: severity_vw incident_type_vw The columns are: incident_tally severity_cd incident_typ_cd Actual Result Data 36 0 ENVIRONMENT 1 1 DISASTER 27 1 ENVIRONMENT 4 2 SAFETY 1 3 SAFETY Required Result Data 36 0 ENVIRONMENT 0 0 DISASTER 0 0 SAFETY 27 1 ENVIRONMENT 0 1 DISASTER 0 1 SAFETY 0 2 ENVIRONMENT 0 2 DISASTER 4 2 SAFETY 0 3 ENVIRONMENT 0 3 DISASTER 1 3 SAFETY Question How would you use UNION, PARTITION BY, or LEFT JOIN to fill in the zero counts?

  • Mysql on duplicate key update + sub query

  • MySQL Query involving column names containing math operators

    - by devil_fingers
    I'm a MySQL scrub, and I have asked around and checked around the internet for what I'm sure will turn out to be something obvious, but I'm very frustrated with what I thought would be a very, very simple query not working. So here goes. Please be gentle. Basically, in a large database, some of the column names contain mathematical operators like "/" and "+." (Don't ask, it's not my database, I can't do anything about it). Here is the "essence" of my query (I took out the irrelevant stuff for the sake of this question): SELECT PlayerId, Season, WPA/LI AS WPALI FROM tht.stats_batting_master WHERE Season = "2010" AND teamid > 0 AND PA >= 502 GROUP BY playerid ORDER BY WPALI DESC When I run this, it returns "Unknown column 'LI' in 'field list'," I assume because it sees the "/" in WPA/LI as a division sign. Like I said, I'm sure this is easy enough to work around (it must be given how much this database is used), but I haven't' been able to figure out how. Thanks in advance for any help.

  • A Better way? C# finding controls, finding their id,

    - by CSharp
    I have a method that finds all the controls, iterates through them, determines if they are a textbox,drop down list, etc.. retrieves their ID name, and depending on the ID name it will set a boolean statement (thus I would know if that section of the form is complete, and will email to a certain group of people) unfortunetly this is done with too many if statements and was wondering if I could get some help making this more manageable ` protected void getEmailGroup() { Control[] allControls = FlattenHierachy(Page); foreach (Control control in allControls) { if (control.ID != null) { if (control is TextBox) { TextBox txt = control as TextBox; if (txt.Text != "") { if (control.ID.StartsWith("GenInfo_")) { GenInfo = true; } if (control.ID.StartsWith("EmpInfo_")) { EmpInfo = true; } } } if (control is DropDownList) { DropDownList lb = control as DropDownList; if (lb.SelectedIndex != -1) { if (control.ID.StartsWith("GenInfo_")) { GenInfo = true; } if (control.ID.StartsWith("EmpInfo_")) { EmpInfo = true; } } } } } }`.

  • Conventional Approaches for Passing Data to Back-End?

    - by Calvin
    Hi guys, I'm fairly new to web development, so please pardon the painfully newbie question that's about to follow. My computer science class group and I are developing a web application for class, which is built in Python (under Django) and uses jQuery on the front end. It's primarily an AJAX-ified application, and passing data from the backend to the front end is done through AJAX calls to specific URLs which return JSON. This is probably a stupid question, but what's the conventional approach for passing data in the opposite direction? We don't want to reload the page or anything, so is it an AJAX pass going the other way or something? Thanks in advance for your help!

  • MPI Barrier C++

    - by aryan
    Dear all, I want to use MPI (MPICH2) on windows. I write this command: MPI_Barrier(MPI_COMM_WORLD); And I expect it blocks all Processors until all group members have called it.

  • how rspec creates database between specs

    - by timpone
    This is a bit of a naive / simple question. I'm having a hard time finding this info online. Basically, does rspec run rake db:test:prepare between every rspec group? Or is it between every example or model? Or does the schema get loaded once and then truncated between each. I need to add a rake task directly after this call to create a view since they are not supported in schema.rb. Either a link or explanation would be greatly appreciated so that I know where to insert my rake task to create a view. Or whether there is a callback like rake db:test:after_prepare thx

  • Referencing outer query's tables in a subquery

    - by soulmerge
    Is it possible to reference an outer query in a subquery with MySQL? I know there are some cases where this is possible: SELECT * FROM table t1 WHERE t1.date = ( SELECT MAX(date) FROM table t2 WHERE t2.id = t1.id)` ); But I'm wondering if something like this could work: SELECT u.username, c._postCount FROM User u INNER JOIN ( SELECT p.user, COUNT(*) AS _postCount FROM Posting p --# This is the reference I would need: WHERE p.user = u.id ) c ON c.user = u.id WHERE u.joinDate < '2009-10-10'; I know I could achieve the same using a GROUP BY or by pulling the outer WHERE clause into the sub-query, but I need this for automatic SQL generation and cannot use either alternative for various other reasons.

  • Extending fluent nhibernate mappings in another assembly

    - by Jarek
    Hi, I'm using NHibernate with my ASP.Net MVC application. I'm writing some extensions (plugins) for my application. And I'm loading those plugin dynamically (from different assemblies). In my base application I have many entities and mappings defined (User, Group, etc...) I need to create new entities in my extensions, so i.e. I'm creating News module, so I need to create News mapping. In database News table has a foreign key to User table. Is there any way I can modify my User mapping, so it will have: HasMany(x => x.Courses) .KeyColumn("GroupId") .Inverse(); Or the only way to do it is to change code in my User class and recompile project ? I'm not NHibernate advanced user, so any help will be appreciated. TIA.

  • Table alias -- Unkown column in field list

    - by Jason
    Hi all, I have a sql query which is executing a LEFT JOIN on 2 tables in which some of the columns are ambiguous. I can prefix the joined tables but when I try to prefix one of the columns from the table in the FROM clause, it tells me Unknown column. I even tried giving that table an alias like so ...From points AS p and using "p" to prefix the tables but that didn't work either. Can someone tell me what I'm doing wrong. Here is my query: SELECT point_title, point_url, address, city, state, zip_code, phone, `points`.`lat`, `points`.`longi`, featured, kmlno, image_url, category.title, category_id, point_id, lat, longi, reviews.star_points, reviews.review_id, count(reviews.point_id) as totals FROM (SELECT *, ( 3959 * acos( cos( radians('37.7717185') ) * cos( radians( lat ) ) * cos( radians( longi ) - radians('-122.4438929') ) + sin( radians('37.7717185') ) * sin( radians( lat ) ) ) ) AS distance FROM points HAVING distance < '25') as distResults LEFT JOIN category USING ( category_id ) LEFT JOIN reviews USING ( point_id ) WHERE (point_title LIKE '%Playgrounds%' OR category.title LIKE '%Playgrounds%') GROUP BY point_id ORDER BY totals DESC, distance LIMIT 0 , 10

  • If a Matlab function returns a variable number of values, how can I get all of them as a cellarray,

    - by kaleidomedallion
    I am writing a function to remove some values from a cellarray, like so: function left = remove(cells, item); left = cells{cellfun(@(i) ~isequal(item, i), cells)}; But when I run this, left has only the first value, as the call to cells{} with a logical array returns all of the matching cells as separate values. How do I group these separate return values into a single cellarray? Also, perhaps there is already a way to remove a given item from a cellarray? I could not find it in the documentation.

  • Rails 2.3.5: How does one add an error when it doesn't make sense to put it in a validation?

    - by randombits
    I recently was trying to add errors.add_to_base code in the middle of some model logic and was wondering why it wasn't showing up in my view that was iterating over all errors. I then ran across this e-mail which explains why: http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/e045ec1dead1ff06?pli=1 The question is then, how does one add errors with add_to_base if it doesn't make sense to put them into a validate method? I have some complex logic. The model needs to talk to a has_many relationship which has its own relationships that go through a myriad of conditionals to figure out if a request makes sense. It's nothing that can be tied to a validate method easily. How does one add errors then accordingly?

  • 600 tables in DDBB

    - by Michael
    Hi all, I'm a very young software architect. Now I'm working in a very large and I have to lead a group of developers to rewrite all the mortgage system of the bank. I'm looking at database tables and I realize that there is no any data model, neither documentation. The worst part is that there are about 1000 tables in dev environment, and like 600 in production. I trust more the production environment, but anyway, what can I do? I mean, I can suicide me or something, but is there any good reverse engineering tool, so at least I could get the schema definition with the relations between tables and comments extracted from the fields? Can you advice me something? Thanks in advance.
