Hiding result sets from multiple selects in a stored procedure

- by Josh Young

I have a stored procedure that retrieves SQL queries as text and executes the statements using sp_executesql. Each of the dynamic queries is a count query in that it only returns the number of records found (select COUNT(id) from...). I am looping through a set of SQL queries stored as text and building a table variable out of the results. At the end, I am selecting all the results from the table variable as the result set that I want returned from the stored procedure. However, when I execute the stored procedure, I am naturally getting multiple result sets (one for each of the dynamic queries and one for the final select.) Is there any way I can suppress the results of a select statement executed through sp_executesql? I have found answers that reference storing the results in a temp table, but I don't have control of the query text that I am running so I can't change it to select into anything. Please help. Thank you for your time.

Check boxes for a has_many and belongs_to association.

- by Thomas

I have a has_many and belongs_to association. class Link < ActiveRecord::Base has_and_belongs_to_many :categories belongs_to :property end class Property < ActiveRecord::Base has_many :links end In the index and show I have <%= link.property.name %> and it will show the Property that I assigned to the link with the console just fine. I have a problem with figuring out how to show check boxes in the _form that assign a property to the link (a drop down would work as well). It seems everyone who has had this question before has ether a has_many :through or a HABTM relationship and I can't seem to adapt their answers.

Transaction within a Transaction in C#

- by Rosco

I'm importing a flat file of invoices into a database using C#. I'm using the TransactionScope to roll back the entire operation if a problem is encountered. It is a tricky input file, in that one row does not necessary equal one record. It also includes linked records. An invoice would have a header line, line items, and then a total line. Some of the invoices will need to be skipped, but I may not know it needs to be skipped until I reach the total line. One strategy is to store the header, line items, and total line in memory, and save everything once the total line is reached. I'm pursuing that now. However, I was wondering if it could be done a different way. Creating a "nested" transaction around the invoice, inserting the header row, and line items, then updating the invoice when the total line is reached. This "nested" transaction would roll back if it is determined the invoice needs to be skipped, but the overall transaction would continue. Is this possible, practical, and how would you set this up?

Import python module NOT on path

- by Vort3x

I have read all the questions I could find on it on SO, but none answers my question. I have a module foo, containing util.py and bar.py. I want to import it in IDLE or python session. How do I go about this? I could find no documentation on how to import modules not in the current directory or the default python PATH. After trying import "<full path>/foo/util.py", and from "<full path>" import util The closest I could get was import imp imp.load_source('foo.util','C:/.../dir/dir2/foo') Which gave me Permission denied on windows 7.

Fake Template Engine php

- by user1464822

i got an idea for making php template engine fast and user friendly but i'm not sure if it's good or bad. the idea is to create a fake template engine: creating a template editor in control panel that let user see something like this: <html> <head> <title>{title}</title> </head> <body> {content} </body> </html> what the editor actually does is to replace all php code like <?php echo $this->title; ?> to user friendly {title} but it's not really replacing it just in the view when the user save the template the template actually saved as fast pure php template. the question is this a good idea or bad ? your answers is highly appreciated.

Lib Files and Defines

- by Paul

I'm using a couple of external libraries and I'd rather not have to include all their source and header files in my main source directory or in my project file. One option would be to compile the libraries as lib files and link them like that. However I'm not sure the defines get evaluated before or after the lib file gets created (which one is it?). If it's before then obviously I can't just pack them because they might not work properly on different compilers or systems. So if I can't pack the libraries as lib files, is there any way for me to link in the c or cpp source files? Probably not, since they would have to be compiled first, but maybe I'm wrong. Edit: Here's a follow-up question, based on answers. Do you think it'd be too much of a hassle to have a makefile that creates the lib files? I'd still rather not add the sources to my project or in my source directory.

Ruby Methods: return an usage string when insufficient arguments are given

- by Shyam

Hi, After creating a serious bunch of classes, with initialize methods, loading them in IRb requires to look back at the code. However, I think it should be easy enough to return a usage message, instead of: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

Environment Variables in C

- by tpar44

I know this type of question has been asked a lot but none of the answers seem to help. I set an environment variable through setenv() function call in Ubuntu Linux. However, the program doesn't seem use this environment variables. If I use getenv() it gets the correct value but the output to the program is wrong. However, when I use export BLOCKSIZE=512 in the shell, the output to the program is correct. I am not spawning different processes from the program. Below is only a code snippet of what I am doing, it is not my whole program. Is there any reason for this?

Representing a very large array of bits in little memory

- by user614624

Hello, I would like to represent a structure containing 250 M states(1 bit each) somehow into as less memory as possible (100 k maximum). The operations on it are set/get. I cold not say that it's dense or sparse, it may vary. The language I want to use is C. I looked at other threads here to find something suitable also. A probabilistic structure like Bloom filter for example would not fit because of the possible false answers. Any suggestions please?

Open dot-file with dialogue in OSX

- by Henrik Paul

Since the GUI-side of OSX treats all dot-files (such as .htaccess) as hidden, it doesn't display them in any of the graphical UI:s, e.g. Finder or the Open-dialogues. How can I open a dot-file (.htaccess in this case) in a graphical editor, without doing that thing for all hidden files, universally and without going through Terminal.app? Edit: I'm on Leopard, if that makes a difference. Edit2: TextWrangler and TextMate seem to have features that allow you to open hidden files, which partly answers my question.

What naming conventions exist for the primary Node.js file?

- by Tom Dworzanski

This question has been completely edited in hopes that it will be reopened. The naming of the main Node.js file is something left to the user and and does not seem to be defined by any well established convention. In hopes of finding a good name, I am curious if there are naming conventions in other parts of the Node.js ecosystem that might suggest a name to use. Some names I have seen are: app.js, index.js, main.js, server.js, etc. Please provide only well documented standards in answers.

What is the easiest way to deploy a MVC2 application from Visual Studio 2010 to IIS 7.5?

- by Richard

I´ve tried a couple of different ways to deploy a application to a IIS 7.5 running on my machine for testing purposes and i´ve sort of hit a wall. Nothing works out of the box. Everything assumes I have knowledge I don't have and would prefer not to have to aqquire. Google isn't really helping either with answers ranging from "copy files by hand" to "install teamcity and set it up for CI". I have set up TeamCity for java projects before and it's really over kill for my needs at the moment. So anyone know of a fast, simple and easy way to deploy a application during testing/building?

continuous deployment with github pages and GAE python

- by BPm

I have a site hosted by google app engine. I've pushed all the html files to a github pages repo and what I want to do next is somehow make GAE listen to my github's changes. Like everytime i commit something new, GAE will deploy itself based on the changes. I've heared of drydrop but that was when github pages didn't exist yet. So what should i do next? I've set up a post-receive url , which is my appspot website, through the github's service hooks, added the CNAME file to my repo which contains my appspot url. Not sure if that's necessary. I've googled a lot on this but none really answers my question. or I just don't know the right search term for it. Thanks in advance

Flex 3 - Full unicode support fonts and CSS

- by BS_C3

Hi! I'm developping a web application that will be used either in Europe or in Asia (specially Japan -Hiragana, Kanji and Katana-, China and Korea). I'm using the following fonts: - ericssonga628.TTF - HelveticaNeueLTStd-Lt.otf - HelveticaNeueLTStd-LtEx.otf - HelveticaNeueLTStd-Bd.otf - HelveticaNeueLTStd-BdEx.otf When I tried to display Japanese characters, I don't get anything. I guess these fonts don't support East Asian characters... Do you know of any equivalent fonts? Also, I was thinking of creating a CSS for each language (or pack of languages) when the user changes the display language. For example, if the user selects "japanese", I'll use the japanese stylesheet. However, how do I switch from a CSS to another? Thanks in advance for your answers. Regards,

Tiling rectangles seamlessly in WPF while maintaing subpixel accuracy?

- by Jens

I have had the problem described in the question Tiling rectangles seamlessly in WPF, but am not really happy with the answers given there. I am painting a bar chart by painting lots of rectangles right next to each other. Depending on the scale of the canvas containing them, there are small gaps visible between some of them as a result from sub-pixel rendering. I learned from the above question how to make my rectangles fit with the screen pixels, removing that effect. Unfortunately, my chart may display way more bars than there are pixels. Apart from the tiny gaps (which manifest as a periodic change in color saturation), this works well. If I snap each bar with the screen pixels, most of the bars vanish, though, so I am looking for another solution. Thanks in advance!

Text to a PNG on App Engine (Python)

- by Bemmu

Note: I am cross-posting this from App Engine group because I got no answers there. As part of my site about Japan, I have a feature where the user can get a large PNG for use as desktop background that shows the user's name in Japanese. After switching my site hosting entirely to App Engine, I removed this particular feature because I could not find any way to render text to a PNG using the image API. In other words, how would you go about outputting an unicode string on top of an image of known dimensions (1024x768 for example), so that the text will be as large as possible horizontally, and centered vertically? Is there a way to do this is App Engine, or is there some external service besides App Engine that could make this easier for me, that you could recommend (besides running ImageMagick on your own server)?

Use Javascript variable in PHP

- by Rhepungus

I have seen some answers to this question in previous posts, but no one has given a real working example, just psuedo code. Has anyone ever done this before? Basically, what i have is a variable in javascript (jquery), and i want to use this variable to drive a query (for an overlay window) i am going to run in php. From what i have read you can do this using an ajax call to the same page so it doesnt refresh itself, but i must be missing something because i can't get it working... Any examples out there? Thanks.

Finding out the version of Dojo

- by Sandeep

I'm kinda new to Dojo toolkit. There are certain issues which I would like to get enlightened (I googled but I didn't get any appropriate & satisfying answers) I have a dojo.js(Perhaps the uncompressed dojo.js downloaded) in my already running application (Developed by another software developer). How to find out which version of dojo.js he has downloaded and is being used right now? (Its not commented. I checked) a) While I'm trying to run my application in IE-8 (Opening a pop-up on click of a button), I get error which is pointing me to this line of code if(dojo.isIE&&window.location.protocol==="file:") Note: Its working fine in IE6 but the issue is with IE8 & to be even more specific the JS error is displayed only for the first time when I'm clicking the button. b) Is it true that dojo 1.3 & above is the best & stable release for IE8?

How can I use a carriage return in a HTML tooltip ?

- by ip

Hi, I'm currently adding verbose tooltips to our site, and I'd like (without having to resort to a whizz-bang jQuery plugin, I klnow there are many!) to use carriage returns to format the tooltip. To add the tip I'm using the 'title' attribute. I've looked around the usual sites and using the basic template of: <a title='Tool?Tip?On?New?Line' >link with tip</a> I've tried replacing the '?' with: <br /> &013; /  \r\n Environment.NewLine (I'm using C#) Neither work. Is it possible ?? WOW! Thanks all - 6 different answers in less than an hour. Thanks indeed!!

Is there a way to have one project build another in Visual Studio?

- by Martin Neal

We are finally getting a source control system in place at work and I've been in charge of setting it up. I've read that it's usually good practice to not include binaries in source control so I haven't. However, we have two all-purpose utility projects (each in their own solution) that generate utility .dll's which are included in almost all of our other projects (all each in their own separate solutions). We add references to the utility dll from our projects. I would like to have our solutions set up in such a way that if the reference dll isn't built, the solution will build the dll for itself, much in the same way a make file checks for its dependencies and builds them when they're out of date or missing. I'm new to build processes with VS so try to keep the answers simple. Any links to general build process overview tutorials would be great too. Googleing for VS references returns a bunch of how-to add references links which is not exactly what I want.

Find mininum unused value in mysql table

- by splattru

I have a MySQL table like this: +--------+-------+ + Server + Port + +--------+-------+ + 1 + 27001 + +--------+-------+ + 2 + 27002 + +--------+-------+ + 4 + 27004 + +--------+-------+ How you can see - here was 27003 port - but it was deleted some time ago (just for example). Is there some way to know the minimum value that is not used (higher than 27000 for example) in mysql table? Or there is no way and I need to make an separate table with all ports and column with "used" or "not used" ? Situation explanation: I am creating game hosting website, and I can use auto-increment for ports, but I will have a lot of deleted/unused ports after some time, and I want to use all of them before increasing port range. Thanks for your answers!

Handling the distinction between undefined- and null-parameters in JavaScript

- by Jakob

I know very well that null and undefined are distinct in JavaScript. However, I can't seem to decide whether or not use that fact when my own functions are passed one of those as its argument. Or, expressed in a different way, should myFoo(undefined) return the same thing as myFoo(null) or is everything fine if it doesn't? Or, in yet another case, since myBar(1, 2, 3) is the same thing as myBar(1, 2, 3, undefined, undefined), should myBar(1, 2, 3, null, null) return the same thing as myBar(1, 2, 3)? I feel that there's potential for confusion in both cases and that a library should probably follow a convention when handling null/undefined. I'm not really asking for personal opinions (so please express those as comments rather than answers). I'm asking if anyone knows if there is a best practice that one should stick to when it comes to handling this distinction. References to external sources are very welcome!

Facebook "->api" permissions

- by Matthieu Marcé

I have trouble using Facebook auth on my website... I'm using the PHP Sdk and I don't understand why I can use some functions like "getLoginUrl"/"getLoginStatusUrl"/"getUser" (with right answers : the facebook session is started, i get the user's facebook ID) and when I want to use something like $me = $facebook->api("/me/permissions"); or just $me = $facebook->api("/me"); there's always an exception and nothing works ... I guess it has something to do with permissions or token maybe, but I don't know what. When the user sign up on my website, I ask permissions I need with this scope : "email,user_about_me,user_location,read_friendlists,publish_stream" A clue that the permissions seem to be ok is that when the exception occures, I ask the user to sign in again (facebook connect) and no window appears as if everything's ok, but still, the page is reloaded and the exception appears again and again... Please help, Thank you !
