• Use LINQ to SQL results inside SQL Server stored procedure

  - by ifwdev

  Note: I'm not trying to call a SQL Server stored proc using a L2SQL datacontext. I use LINQPad for some fairly complex "reporting" that takes L2SQL output saved to an Array and is processed further. For example, it's usually much easier to do multiple levels of grouping with LINQ to Objects instead of trying to optimize a T-SQL query to run in a reasonable amount of time. What would be the easiest way to take the end result of one of these "applications" and use that in a SQL Server 2008 stored proc? The idea is to use the data for a Reporting Services Report, rather than copying and pasting into Excel (manual labor). The reports need to be accessible on the report server (not using the Report Server control in an application). I could output CSV and read that somehow via command line exec, but that seems like a hack. Thanks for your help.

• High level audio crossfading library for python

  - by tcoopman

  I am looking for a high level audio library that supports crossfading for python (and that works in linux). In fact crossfading a song and saving it is about the only thing I need. I tried pyechonest but I find it really slow. Working with multiple songs at the same time is hard on memory too (I tried to crossfade about 10 songs in one, but I got out of memory errors and my script was using 1.4Gb of memory). So now I'm looking for something else that works with python. I have no idea if there exists anything like that, if not, are there good command line tools for this, I could write a wrapper for the tool.

• What are the ways to create draw data structures for latex?

  - by alicephacker

  I tried tikz/pgf a bit but have not had much luck creating a nice diagram to visualize bitfields or byte fields of packed data structures (i.e. in memory). Essentially I want a set of rectangles representing ranges of bits with labels inside, and offsets along the top. There should be multiple rows for each word of the data structure. This is similar to most of the diagrams in most processor manuals labeling opcode encoding etc. Has anyone else tried to do this using latex or is there a package for this?

• How exactly does a program convert everything to UTF-8 internally?

  - by xyld

  does it use setlocale()? does it assume utf-8 for all input strings when in a UTF-8 locale? I understand what unicode is and how it is related to utf-8, but how does one "convert to it" internally with all their strings? How does it convert all input strings to UTF-8? Does it use a C library function? Does the current working locale have to be a UTF-8 locale? UPDATE: if specific technical details could be in your answer, that would be great as that is more along the lines of what I'm looking for. I already understand the reasons for using UTF-8 internally and why it makes dealing with multiple locales much simpler.

• direct access to vector elements similar to arrays

  - by mixm

  hi. im currently creating a tile based game, where elements of the games are placed in four different vectors (since there are multiple game objects with different properties, hence stored in different vectors). these game elements themselves contain x and y coordinates similar to how they are stored in a two dimensional array. i was wondering if there was a way to access these vector elements similar to two dimensional array access (currently i am implementing an for loop to cycle the elements while comparing its coordinates). this kinda sucks when i need to refresh my display at every game cycle (since the large number of comparisons and loops). im implementing this in java btw.

• HttpHandler with Flash file upload question

  - by Projapati

  I have a flash file uploader that allows uploading multiple files in one shot. Now on one click how many times will the hanlder is supposed to be called? I am seeing that the ProcessRequest() of the HttpHandler is getting called for each of the files I upload. If I upload 5 files, then the Process request gets called 5 times. This seems odd. I would expect the handler to be called just once where I will loop the Can anyone confirm this behavior or I am missing something?

• Learning about version control systems, Git, SVN

  - by anijhaw

  I am a basic SVN user now trying to learn GIT for a new position. I am trying the usual reading docs and watching videos. However after doing all that I still feel that there is a lot that I do not know. I was wondering if there is a place like project Euler for programming languages, that provides a series of exercises that you can do just to increase your confidence and test your knowledge about a version control system. Something thats generic enough and gets you up to speed with how to do basic things. This could also serve as a comparison point of sorts between multiple VCSs, that would show what things are easy in which VCS. If there is nothing I was planning to document my journey in learning GIT and the create an exercise of this sort.

• ASP.Net MVC - which is the best approach for multi select grouping using JQuery Dialog

  - by Rajeesh

  This is my scenario I have an view(page) with list of items, a user could select single or multiple items from this page and click on a "Add to Group" button. Then a modal dialog(JQuery dialog) will be shown, from that he could select group, then press the add button. Which causes the items selected in the parent page is added to that particular group. So, which is the best way to pass the selected items to the modal pop-up? Though the query string ? - what happens if the no:of items selected is large, will the url support that much characters Keep the list in the parent page in a javascript variable and return the selected group from the modal pop-up? Or is there is any other better option? Thanks, Rajeesh

• rails 3, active record: any way to tell how many unique values match a "x LIKE ?" query

  - by jpwynn

  I have a query to find all the phone numbers that match a partial expression such as "ends with 234" @matchingphones = Calls.find :all, :conditions => [ "(thephonenumber LIKE ?)", "%234"] The same phone number might be in the database several times, and so might be returned multiple times by this query if it matches. What I need is to know is UNIQUE phone numbers the query returns. For example if the database contains 000-111-1234 * 000-111-3333 000-111-2234 * 000-111-1234 * 000-111-4444 the existing query will return the 3 records marked with * (eg returns one phone number -1234 twice since it's in the database twice) what I need is a query that returns just once instance of each match, in this case 000-111-1234 * 000-111-2234 *

• How to prepare a codebase for compiling on both Windows and Unix-based systems

  - by Max

  Hi! I am wondering about different solutions to easily compile my cross-platform application for both windows and unix. Right now I am using a makefile on Ubuntu, but before my codebase grows larger I'd like to perform the steps necessary to compile it on Windows, and then continue doing so regularly to see that it still works. I'd preferably not contaminate my SVN codebase repository with multiple "makefile" solutions, such as VC++ solutions and so on, I'd like a more automatic way. I tried using mingw with make for windows, but it seems my secondexpansion awesomeness doesn't work on the Windows version (or something like that). It wouldn't compile, and also complained about _winNT or something like that not being defined. How should I prepare my codebase for cross-platform easy compiling? Things like buildtools, perhaps autogenerate VS file from makefile, or something similar. Some preprocessor magic in a stdinc file perhaps? Thanks!

• Split string into smaller part with constrain [PHP RegEx HTML]

  - by Sadi

  Hello, I need to split long string into a array with following constrains: Each part will have a limited number of character (e.g. not more than 8000 character) Each part can contain multiple sentences (delimited by . [full stop]) but never a partial sentences. Except if the last part of the string (as last part may not have any full stop. The string may contain HTML tags. But the tag can not be divided as ( to ). That means HTML tag should be intact. But starting tag and ending tag can be stay on different segment/chunk. I think regular expression with preg_split can do it. Would please help me with the proper RegEx. Thank you Sadi

• Routing WCF Traffic Based on URI Domain Requested

  - by Ian Patrick Hughes

  Is there a way to route traffic to a target WCF service file based on the URL domain requested? Basically, I have a single WCF RESTful services project with 3 service files offering different endpoints. It's hosted on a single IIS6 site looking for multiple host header values on port 80. I want to route traffic to different services files whether the requester is asking for www.site1.com, www.site2.com, or www.site3.com. Seems like the sort of thing I would use a global.asax or HTTP Handler for, but I am not sure since this is a regular WCF Service Application. Even though I am on IIS6 for this project, I don't mind using a URL re-writer and wildcard mapping, if I have to. I have admin rights on the balanced servers where this will reside, I just want to know if there is a common/best practice before I start hacking my way around this.

• JQuery drag and Drop

  - by dremay

  I wish to create an Interface to choose Multiple answers using Drag & Drop rather than CheckBox near to the answers. User can choose two types of answers (Real Answer and a Fake Answer). The User has Two Images (for Real & Fake) on the answer page. User can drag an Image and drop near to the selected answer. It is possible to change the selection by moving the "image and drop over some other answer". I have used a "div formatted with an image" near to all answers, so user can drop the image (ie fake or real image) over this "div". I have used JQuery to move the "image" and drop over the "div". Now I need add the code to the "div" (ie container used to hold the image) to identify which "image is placed over it" ie either "fake or real".

• preg_replace only replaces first occurrence then skips to next line

  - by Dom

  Got a problem where preg_replace only replaces the first match it finds then jumps to the next line and skips the remaining parts on the same line that I also want to be replaced. What I do is that I read a CSS file that sometimes have multiple "url(media/pic.gif)" on a row and replace "media/pic.gif" (the file is then saved as a copy with the replaced parts). The content of the CSS file is put into the variable $resource_content: $resource_content = preg_replace('#(url\((\'|")?)(.*)((\'|")?\))#i', '${1}'.url::base(FALSE).'${3}'.'${4}', $resource_content); Does anyone know a solution for why it only replaces the first match per line?

• email tracking image duplicate requests

  - by DEH

  I am embedding tracking images within emails that are being sent from a custom-built opt-in CRM system. The image src is an encoded .gif, such as src="12_34_675.gif". The image is served by an ASP.NET httphandler that decodes the src encoding and serves a transparent image. Everything works fine, but some email clients request the image multiple times, creating duplicate entries. Some clients make three calls all within one second, and some seem to make tens of calls over a day or so. Mostly email clients make single calls, but these few duplicates are very perplexing. I know I can code around them, but I'd really like to understand what's going on. I've checked the IIS log files, which show that the duplicate requests are coming from the client machines. I can't think what might be causing these duplicate http requests. Help!

• Get old text from change event?

  - by Biroka

  Can I somehow find out what was the change in the textfield? I would want to compare the old text with the new text ... the problem is, that I have multiple textAreas in a tab-editor, and all the textAreas are watched by one eventListener. I want to get a value calculated by the next formula: globalChangeCount += thisTextArea.currentCharacterCount - thisTextArea.oldtCharacterCount where the globalChangeCount is a value modified by all changes in any of the textAreas. I am searching for these values through the event variable, but can't seam to find the old text of the textArea.

• Finding many local max in an image (using MatLab)

  - by wenh42

  How do you go about figuring our multiple max in a 2D image where the max aren't necessarily all the same height? I have found that the imregionalmax(), imextendedmax(), and findpeaks() functions aren't necessarily that helpful because they give many local max that are really just maxes within the background noise. I tried bw=arrayimdilate(array,[1 1 1; 1 0 1; 1 1 1]) but that also is kind of limited for the same reasons (same thing with expanding the matrix that it uses). I'd definitely appreciate some help..

• How do I use a batch copy to update files?

  - by Aaron

  Hello, I need help writing a batch file to update templates on a database. Basically, all our clients have their own folder, with multiple templates inside. Due to the computer illiteracy of my office (sigh), there's no real better way to fix this. However, I need a way to update those templates in a batch. For instance \\SERVER\New Client Template Folder\Correspondence\Transmittal Letter.WPD is updated. I then need to copy it to: \\SERVER\Client Files\Client 1\Correspondence; \\SERVER\Client Files\Client 2\Correspondence; ...etc. Essentially, I need to copy to \\SERVER\Client Files\\*\\, and I need to make it a batch file that I can train someone else to use whenever I leave this job. How can I do that? Thanks.

• jKey (JavaScript key shortcut plugin) Issue

  - by Oscar Godson

  Me and a friend are writing a plugin for jQuery that makes it easy for devs to add key shortcuts and we're damn close but no cigar. We're having issues with the key combos. It seems like we are having issues when you call the same selector multiple times on a page. Try pressing alt+a... youll see it works one time, then gets all mangled up. Anyone know how to fix it? It'll be on github after it's corrected and I'd be happy to add "thank you to" link to whoever can fix this in the header with the copyright info :) It's nicely documented and i have all the code and stuff here. So... anyone? http://jsbin.com/azaha4

• Django get_FOO_display and distinct()

  - by datakid

  I've seen answers to both halves of my question, but I can't work out how to marry the two. I have a book model, and a translatedBook model. The translatedBook has a langage set up as model choices in the usual way: LANGUAGES = ( (u'it', u'Italian'), (u'ja', u'Japanese'), (u'es', u'Spanish'), (u'zh-cn', u'Simplified Chinese'), (u'zh-tw', u'Traditional Chinese'), (u'fr', u'French'), (u'el', u'Greek'), (u'ar', u'Arabic'), (u'bg', u'Bulgarian'), (u'bn', u'Bengali'), etc I know that to get "Italian" I have to do translatedBook.get_language_display on a Book object. But how do I get a list of distinct languages in their long format? I've tried: lang_avail = TargetText.objects.values('language').distinct().order_by('language') lang_avail = TargetText.objects.distinct().order_by('language').values('language'). lang_avail = TargetText.objects.all().distinct('language').order_by('language') but I can't seem to get what I want - which is a list like: "English, Italian, Simplified Chinese, Spanish" The final lang_avail listed above didn't return the list of 5, it returned the list of 355 (ie, # of books) with multiple repeats....

• If don't own proprietary database engine, what is best way to convert database to mysql?

  - by John Robertson

  I work for a very small company. I was recently faced with the question of whether there is a good way to convert a proprietary database to a MySQL database without owning the proprietary database engine e.g. if one is given a large oracle database file (or choose your favorite proprietary database engine format), but doesn't have a license for the oracle database engine, is there a good, perfectly reliable way to convert it to a MySQL database format that can be read with the MySQL database engine? My question is very vague as to which proprietary format is the source just because there would be multiple sources and it looks like they would be "various and sundry". My suspicion is that there is no perfectly reliable way, especially for a wide variety of proprietary databases. If there are a few proprietary formats for which this is possible, I would still be interested in knowing, though "various and sundry" is probably the real issue. Minimizing cost, effort and correct conversion are key so I think this is probably is the not possible list. -John

• INSERT INTO statement that copies rows and auto-increments non-identity key ID column

  - by AmoebaMan17

  Given a table that has three columns ID (Primary Key, not-autoincrementing) GroupID SomeValue I am trying to write a single SQL INSERT INTO statement that will make a copy of every row that has one GroupID into a new GroupID. Example beginning table: ID | GroupID | SomeValue ------------------------ 1 | 1 | a 2 | 1 | b Goal after I run a simple INSERT INTO statement: ID | GroupID | SomeValue ------------------------ 1 | 1 | a 2 | 1 | b 3 | 2 | a 4 | 2 | b I thought I could do something like: INSERT INTO MyTable ( [ID] ,[GroupID] ,[SomeValue] ) ( SELECT (SELECT MAX(ID) + 1 FROM MyTable) ,@NewGroupID ,[SomeValue] FROM MyTable WHERE ID = @OriginalGroupID ) This causes a PrimaryKey violation since it will end up reusing the same Max(ID)+1 value multiple times as it seems. Is my only recourse to a bunch of INSERT statements in a T-SQL WHILE statement that has an incrementing Counter value? I also don't have the option of turning the ID into an auto-incrementing Identity column since that would breaking code I don't have source for.

• Storing SQL queries in Table in sql server

  - by Rohit

  We have multiple jobs in our system.These jobs are listed in a grid. We have 3 different user types (usertypeid 1,2,3). For each user listing is different and he can filter listing by selecting view from a dropdown. ViewName in the below table is the view which needs to be displayed. To achieve this functionality, a fellow developer has created the following table structure and stored sql fragments in SQLExpression in the below table. According to me the query should not be stored in database. What are the pros and cons of this approach and what are the available alternatives? JobListingViewID ViewName SQLExpression UserTypeID 3 All Jobs 1 = 1 3 4 Error Jobs JobStatusID IN ( 2 ) 1 5 Error Jobs JobStatusID IN ( 2 ) 2 6 Error Jobs JobStatusID IN ( 2 ) 3 7 Speech JobStatusID IN ( 1, 3, 8 ) 1

• Filling in a multi-choice field in a Sharepoint Doc-Lib using SetDocsMetaInfo Frontpage Server Extentions RPC method

  - by notnot

  I've been given a big chunk of code which eventually calls upon the SetDocsMetaInfo method from Frontpage Server Extension RPC. This is easy enough for most document uploading and property updating, except when dealing with multichoice fields. I've been scouring through MSDN and I can't find anything on how to fill in multiple values for such a field. The general syntax for properties is something like this: [SR|default], with the type (string in this case) followed by a pipe and then the value to be written. Does anyone know the syntax for multichoice fields? references: MSDN: SetDocsMetaInfo

• Where would async calls make sense in an ASP.net (MVC) Web Application?

  - by Michael Stum

  I'm just wondering, if I have an ASP.net Web Application, either WebForms or MVC, is there any situation where doing stuff asynchronously would make sense? The Web Server already handles threading for me in that it spins up multiple threads to handle requests, and most request processing is rather simple and straight forward. I see some use for when stuff truly is a) expensive and b) can be parallelized. but these are the minority cases (at least from what I've encountered). Is there any gain from async in the simple "Read some input, do some CRUD, display some output" scenario?
