  • Separate one-off code paths

    - by DeadMG
    I'm implementing an application with different code paths that shall be chosen once at startup and then fixed forevermore for that execution- for example, choosing D3D11 or D3D9 rendering path. Obviously I don't want to duplicate all my other code. Is run-time inheritance (no virtual inheritance) a fair solution? I don't want to waste a bunch of performance making virtual lookups when the type was fixed long ago. Not just that, but it makes me nervous that the functions can't be inlined and whether or not it affects RVO and NRVO and such. Am I just being over-concerned about this?

  • What is the reason not to use select * ?

    - by Chris Lively
    I've seen a number of people claim that you should specifically name each column you want in your select query. Assuming I'm going to use all of the columns anyway, why would I not use SELECT *? Even considering the question from 9/24, I don't think this is an exact duplicate as I'm approaching the issue from a slightly different perspective. One of our principles is to not optimize before it's time. With that in mind, it seems like using SELECT * should be the preferred method until it is proven to be a resource issue or the schema is pretty much set in stone. Which, as we know, won't occur until development is completely done. That said, is there an overriding issue to not use SELECT *?

  • Using generics in dotnet for functions with any number of arguments?

    - by Zarigani
    I would like to have a function that can "wrap" any other function call. In this particular case, it would allow me to write some more generic transaction handling around some specific operations. I can write this for any particular number of arguments, e.g. for one argument: Public Shared Sub WrapFunc(Of T)(ByVal f As Action(Of T), ByVal arg As T) ' Test some stuff, start transaction f(arg) ' Test some stuff, end transaction End Sub ... but I was hoping to have this handle any number of arguments without having to have duplicate code for 0 args, 1 arg, 2 args, etc. Is there a way of doing this?

  • importing data using get or create - identity error 1062

    - by hamackey
    I am importing data from a mssql database into mysql. Works except when it encounters the id of a previous entry. id is unique. I need to get entries that already exist so that they can be placed in the work of the day. Error is IntegrityError: (1062, "Duplicate entry '001355338' for key 2") This entry is already in the database. I need it entered for that day, but can not have it added to the table. It is already there. def handle(self, *args, **options): 59 #patients_local = Patient.objects.all() 60 #attendings_local = Attending.objects.all() 61 connection = pyodbc.connect("XXXXXXXXXXX") 62 cursor = connection.cursor() 63 cursor.execute(COMMAND) 64 rows = cursor.fetchall() 65 for row in rows: 66 # get_or_create returns (object, boolean) 67 p, created = Patient.objects.get_or_create( 68 first_name = row.Firstname, 69 middle_name = '', 70 last_name = row.Lastname, 71 id = row.id, 72 )

  • Not a statement?

    - by abelenky
    I have a simple little code fragment that is frustrating me: HashSet<long> groupUIDs = new HashSet<long>(); groupUIDs.Add(uid)? unique++ : dupes++; At compile time, it generates the error: Only assignment, call, increment, decrement, and new object expressions can be used as a statement HashSet.Add is documented to return a bool, so the ternary (?) operator should work, and this looks like a completely legitimate way to track the number of unique and duplicate items I add to a hash-set. When I reformat it as a if-then-else, it works fine. Can anyone explain the error, and if there is a way to do this as a simple ternary operator?

  • how can I deliver remote content via web service?

    - by Slinky
    We have multiple websites under different domains that need to receive our banner ads. We have a server app, in PHP, that returns the HTML for a randomly-generated banner ad. Out of concern for the client side, I don't want to use an iframe nor do I want to include the jquery library because of the weight - I also do not want to duplicate code across all the domains. Any other way to do this? Maybe there is a way to do this with mod rewrite or a web service? Anyone solve a similar problem? Thanks

  • SQL Server 2000, how to automate import data from excel

    - by Stan
    Say the source data comes in excel format, below is how I import the data. Converting to csv format via MS Excel Roughly find bad rows/columns by inspecting backup the table that needs to be updated in SQL Query Analyzer truncate the table (may need to drop foreign key constraint as well) import data from the revised csv file in SQL Server Enterprise Manager If there's an error like duplicate columns, I need to check the original csv and remove them I was wondering how to make this procedure more effecient in every step? I have some idea but not complete. For step 2&6, using scripts that can check automatically and print out all error row/column data. So it's easier to remove all errors once. For step 3&5, is there any way to automatically update the table without manually go through the importing steps? Could the community advise, please? Thanks.

  • How to use rvm (ruby version manager) with root account?

    - by Jade
    The whole point of rvm is to be able to install multiple rubies and access them from a user account. What do you do when you need to access any of those rubies from root? Or use gems installed in one of those rvms? Is there an elegant (or even hackish) way to use these I haven't considered? My guess is that I should just add it to my PATH, but I'm curious if anyone has come up with a better idea. I'd rather not install rvm just for the root account and duplicate everything.

  • Truncating a table referenced by a foreign key

    - by born to hula
    Hey, We have two tables in a SQL Server 2005 database, A and B.There is a service which truncates table A every day. Recently, a foreign key constraint was added to table B, referencing table A. As a result, it isn't possible truncating table A anymore, even if table B is empty. Is there any workaround to get the same result as truncating table A? I've already tried the approach below but the identity wasn't reset. DBCC CHECKIDENT (TABLENAME, RESEED, 0) PS. before anyone points this as a duplicate, the different thing here is that I'm not allowed to drop constraints, nor creating any.

  • Where Should Using Statements Be Located [closed]

    - by Bobby Ortiz - DotNetBob
    Possible Duplicate: What is the difference between these two declarations? I recently started working on a project with using statement located inside the NameSpace block. namespace MyApp.Web { using System; using System.Web.Security; using System.Web; public class MyClass { I usually put my using statements above the namespace block. using System; using System.Web.Security; using System.Web; namespace MyApp.Web { public class MyClass { I don't think it matters, but I am currious if someone else had a recommendation and could they explain why one way is better than another. Note: I always have one class per file.

  • Suggestion To Stackoverflow [closed]

    - by Eddy Freeman
    Hello Stackoverflow Team, This is just a suggestion to you. In the first place i must say that you guys are doing a great job. I suggest that you build into the forum system a mail notifier(to notify users whenever there is a move/deletion of a post with the reason of the move/deletion) so that whenever you move or removed someone's post then he can be notified about the move, so that we don't spend time looking for posts that are removed. I think by so doing the number of duplicate posts and mistakes from users can be minimized. The reason is i spent hours searching through the posts to locate my posts that you have re/moved. That is why i was a little bit upset. Sorry if here is the wrong place to post my suggestion. Point me to the right place. Thanks for your work.

  • WPF: how to make normal listbox left-drag-select behavior use middle mouse instead?

    - by Scott Bilas
    I'm building a special listbox control that our designers want customized in some tweaky ways. One thing they want to see is that the middle button-drag does what the left button-drag normally does (we are repurposing left-drag to other things). So it needs the two key features that left-drag does in a ListBox default implementation: While holding down the button and dragging, the selection starts where I click down and extends to where I drag. While dragging outside the listbox region, it scrolls if there is scrollable space in that direction. Before I go an duplicate this functionality by hand, is there any easy way to fool ListBox into thinking it's getting left-mouse drag events but instead is getting middle-mouse?

  • How to generate random strings that match a given regexp?

    - by Pies
    Duplicate: Random string that matches a regexp No, it isn't. I'm looking for an easy and universal method, one that I could actually implement. That's far more difficult than randomly generating passwords. I want to create an application that takes a regular expression, and shows 10 randomly generated strings that match that expression. It's supposed to help people better understand their regexps, and to decide i.e. if they're secure enough for validation purposes. Does anyone know of an easy way to do that? One obvious solution would be to write (or steal) a regexp parser, but that seems really over my head. I repeat, I'm looking for an easy and universal way to do that. Edit: Brute force approach is out of the question. Assuming the random strings would just be [a-z0-9]{10} and 1 million iterations per second, it would take 65 years to iterate trough the space of all 10-char strings.

  • I can't Distinct, Sum, or Count from 3 tables with group clauses

    - by Rio Inggit Dharmawangsa
    I'm still learning linq, now i'm getting confused. I need data for report from 3 tables, I get the result, but it's duplicate. I have used distinct but it's not working, n I need data to be sum still not working.

  • Copy new records from datatable and identify changes in old records

    - by Betite
    Assume there are two tables: Remote_table and My_table. Remote_table has 6 columns: **PROJECT JOB_TYPE MONTH YEAR** HOURS IS_DELETED 134393 70 1 2013 30 0 134393 70 2 2013 50 0 134393 70 3 2013 80 0 134393 70 10 2012 10 0 134393 70 11 2012 0 0 134393 70 12 2012 15 0 My_table is a copy of remote_table. I tried to copy only the new records from the remote_table by this query: SELECT * FROM [remote_DB].[LudanProjectManager].[dbo].Remote_table EXCEPT SELECT * FROM My_table It works OK but I get a duplicate primary key exception when changes have been made on the remote_table on the hours column. Can anyone think of a way to copy only the new records from remote_table and if changes has been made on old records, to identify them and update the my_table to correspond?

  • Use a named custom column in SQL 2005 in WHERE clause?

    - by Orange Kid
    Can I name a custom column in the SELECT statement and reference that in the WHERE clause without duplicating code? For example; SELECT RIGHT(REPLICATE('0', 5) + RTRIM(SOME_ID)), 5) AS DISPLAY_ID FROM dbo.MY_TABLE WHERE DISPLAY_ID LIKE '%005%' Only much more complicated. I want to maintain this code in one place only but SQL Server 2005 forces me to duplicate the custom SELECT in the WHERE clause. I believe this was possible in Microsoft SQL Server 2000 but no longer in 2005. Thanks.

  • Save or update for FK relationship Sqlalchemy

    - by Alex
    I've googled, but haven't been able to find the answer to this seemingly simple question. I have two relations, a customer and an order. Each order is associated to a single cusomter, and therefore has a FK relationship to the customer table. The customer relation only stores customer names, and I have set a unique constraint on the customer table barring duplicate names. Let's say I create a new order instance and set a customer for the order. Something like: order_instance.customer = Customer("customer name") When I save the order instance, SqlAlchemy will complain if a customer with this name already exists in the customer table. How do I specify to SqlAlchemy to insert into the customer table if a customer with this name doesn't already exist, or just ignore (or even update) to the customer relation? I don't really want to have to check each time if a customer with some name already exists...

  • How to update existing record if the one being saved has the same key?

    - by Pavel Shved
    MySQL has a very nice option for INSERT statement, which is particularly helpful for join tables without the id column. It inserts a record, but, instead of throwing an error if its key clashed with the existing one, that record is updated. Here's an example: INSERT INTO table (key1,key2,data) VALUES (1,2,3) ON DUPLICATE KEY UPDATE c=3; How to achieve the same with ActiveRecord? The code looks like this: class Model < ActiveRecord::Base belongs_to :key1 belongs_to :key2 end record = Model.new record.key1 = key1 record.key2 = key2 record.data = 'new data' record.WHAT? #Inserts or updates `data` for the existing record

  • How do I conditionally assign ruby variables to javascript variables?

    - by Tony
    I have a website where I need a javascript version of the "current user" object along with the ruby version. I have been assigning these variables doing something like this... Application Controller: def get_user begin @current_user = User.find(session[:user_id]) if session[:user_id] @current_user_json = @current_user.to_json rescue session.delete(:user_id) @current_user = nil @current_user_json = {} end end Web Page: var current_user = null; current_user_json = '<%= @current_user_json %>'; if(current_user_json != ''){ current_user = current_user_json.user; } Even when there is a current user, I get the current user is undefined. Probably because I am putting the current_user_json assignment around single quotes. However, if I don't put it around single quotes, I'll always get a javascript error when no user is logged in because the syntax is invalid - current_user_json = ; I think I am just looking at this completely wrong and there must be a better way. Given that this is probably a common thing to do, I wanted to get other people's opinion on how to create an object in javascript that is a duplicate of the ruby object.

  • How to dynamically add a Javascript function (and invoke)

    - by whitey
    Based on a click event on the page, via ajax I fetch a block of html and script, I am able to take the script element and append it to the head element, however WebKit based browsers are not treating it as script (ie. I cannot invoke a function declared in the appended script). Using the Chrome Developer Tools I can see that my script node is indeed there, but it shows up differently then a script block that is not added dynamically, a non-dynamic script has a text child element and I cannot figure out a way to duplicate this for the dynamic script. Any ideas or better ways to be doing this? The driving force is there is potentially a lot of html and script that would never be needed unless a user clicks on a particular tab, in which case the relevant content (and script) would be loaded. Thanks!

  • PHP mail sending duplicates with different timestamp

    - by brhea
    Hi all, I've got a PHP/AJAX form on my site at http://www.brianrhea.com (click Request Project) When I test the form from multiple computers, it works fine for me. However, I will sporadically receive a duplicate e-mail and have heard from at least one user who tried to submit that it gave them an alert error which I am unable to duplicate. This is the PHP that I'm using. Is there anything that stands out as a potential issue? <?php //Retrieve form data. //GET - user submitted data using AJAX //POST - in case user does not support javascript, we'll use POST instead $name = ($_GET['name']) ? $_GET['name'] : $_POST['name']; $email = ($_GET['email']) ?$_GET['email'] : $_POST['email']; $subject = ($_GET['subject']) ?$_GET['subject'] : $_POST['subject']; $comments = ($_GET['comments']) ?$_GET['comments'] : $_POST['comments']; //flag to indicate which method it uses.

  • How should I synchronize lists in WCF?

    - by mafutrct
    I've got a WCF service that offers multiple lists of items of different types. The lists can be changed on the server. Every change has to be published to all clients to make sure every client has an up-to-date copy of each server list. Currently I'm using this strategy: On login, every client receives the current status of every list. On every change, the added or removed item is sent to all clients. The drawback is that I have to create a callback for every list, since the items are of different types. Is there a pattern I could apply? Or do I really have to duplicate code for each of the lists?

  • MySQL: Selecting One Record When Others Have Same Data

    - by LoganFrederick
    I have a table of cities that all share the same area code: 367 01451 Harvard Worcester Massachusetts MA 978 Eastern 368 01452 Hubbardston Worcester Massachusetts MA 978 Eastern 369 01453 Leominster Worcester Massachusetts MA 978 Eastern The table has multiple area codes, all with multiple cities. What I'd like to do is only select one city from each area code and delete any extra cities from duplicate area codes. What would be the best query to accomplish this? I believe: http://stackoverflow.com/questions/596629/mysql4-sql-for-selecting-one-or-zero-record Is coming close to what I need but didn't quite get what/how those answers were working. Note The "978" row is the "area_code" row, table name is "zip_code".

  • SEO URL Structure

    - by Neil
    Based on the following example URL structure: mysite.com/mypage.aspx?a=red&b=green&c=blue Pages in the application use ASP.net user controls and some of these controls build a query string. To prevent duplicate keys being created e.g. &pid=12&pid=10, I am researching methods of rewriting the URL: a) mysite.com/mypage.aspx/red/green/blue b) mysite.com/mypage.aspx?controlname=a,red|b,green|c,blue Pages using this structure would be publishing content that I would like to get indexed and ranked - articles and products (8,000 products to start, with thousands more being added later) My gut instinct tells me to go with the first method, but would it would be overkill to add all that infrastructure if the second method will accomplish my goal of getting pages indexed AND ranked. So my question, looking at the pro's and con's, Google Ranking, time to implement etc. which method should I use? Thanks!
