  • Splitting string to integer from single-line user input?

    - by pootzko
    I just started learning some ruby, and I want to do something like this: print "Insert two numbers: " a, b = gets.split(" ") but I want to make a and b to be integers at the same time (in the same line).. If I add .to_i to the second line (before or after split(" ")), it doesn't work... so, how should I approach this? mapping, splitting, slicing? ok, I know I could use scanf, but other than scanf, how would I do this? sorry for such a noobish question, but I just couldn't find a good enough answer only googling...

  • Multiple connections to a MySQL database in a single PHP script.

    - by st3
    There are multiple times in one page where I need to connect and subsequently query a MySQL database, yet my code won't let me. I think it might be something to do with how my files are nested but it makes no sense. I am opening the SQL connection in the header file. The top of the offending page looks like the following: <?php $page_title = 'Dashboard'; include('templates/header.inc'); // includes a 'require_once('mysqli_connect.php') and a small query to the database; require_once('includes/functions.php'); require_once('includes/dashboard_sql.php'); // Contains functions which connect to database (which are failing.) ?> I get the PHP error Notice: Undefined variable: dbc in /Library/WebServer/Documents/pediatory_site/includes/dashboard_sql.php Where $dbc is the database connection defined in mysqli_connect.php. If anyone could help me out that would be great.

    I have one employee table...this table has 5 coloumns (empname, empgsm, empsal, empaddr, empdep)...it has 10 records. i've created 10 users equivelent to the empnames coloumn in the table.

  • Can I run multiple websites under a single membership database?

    - by higgsy
    Hi all, I'm trying to plan a series of websites that all share many of the resources such as css/jscript/images/content etc. For this reason I wanted to run all of the websites under the same application and IIS profile, but depending on the URL being used change the masterpage and theme/skin. The ASP.NET membership database seems as if it was designed with this goal in mind because it allows you to setup multiple applications, however I believe the purpose for which this was built was to allow applications to be run under virtual directories/fodlers, not on seperate urls. Is it possible to map a url to a particular application? Thanks in advance Al

  • Can I lock rows in a cursor if the cursor only returns a single count(*) row?

    - by RenderIn
    I would like to restrict users from inserting more than 3 records with color = 'Red' in my FOO table. My intentions are to A) retrieve the current count so that I can determine whether another record is allowed and B) prevent any other processes from inserting any Red records while this one is in process, hence the for update of. I'd like to do something like: cursor cur_cnt is select count(*) cnt from foo where foo.color = 'Red' for update of foo.id; Will this satisfy both my requirements or will it not lock only the rows in the count(*) who had foo.color = 'Red'?

  • Lucene.Net - How to treat a space-seperated phrase as a single token?

    - by Gareth D
    I've implemented a search facility using Lucene.Net. The index includes UK academic qualifications, including "A Level". I'd like the users to be able to search using the phrase "A Level", but using the Standrad Analyser the "A" is stripped out as a stop-word and therefore only "Level" is indexed/searched. What's my best option to work around this? I'm guessing I need to somehow tokenise "A Level" to "A-Level" or similar by creating a custom analyser. Is this the best approach? Note that I want don't want the whole search to be a phrase query. i.e. in my search box I want the user to be able to enter <"A Level" AND English Maths Physics and this would return any with "A Level" and either of English MAths or Physics. Question updated to reflect this.

  • Is it possible to retrieve only a single property from a CSS class?

    - by werner5471
    Example CSS File: .testClass { color: black; background: red; } Now in an HTML file, I would like to have something like <span class="testClass:color">Text in black but without red background</span> to only apply the color property of that class. Is there a way to do this? The purpose behind it (for people asking themselves "Why the hell would he want that, that's not clean CSS usage!") is that I use jQuery UI themes, and I would like the entire page to fit a theme upon change. As not all kinds of elements (e.g. the color of a link) are covered by those themes, in those cases I would like to "steal" the color property (but not more) of some other CSS class of the jQuery UI theme. If there is another way to do this, of course I'm glad to hear it as well!

  • How do we match any single character including line feed in Perl regular expression?

    - by bobo
    I would like to use UltraEdit regular expression (perl) to replace the following text with some other text in a bunch of html files: <style type="text/css"> #some-id{} .some-class{} //many other css styles follow </style> I tried to use <style type="text/css">.*</style> but of course it wouldn't match anything because the dot matches any character except line feed. I would like to match line feed as well and the line feed maybe either \r\n or \n. How should the regular expression look like? Many thanks to you all.

  • PHP Curl Not formatting quotes properly; producing weird character set for single/double quotes

    - by user595052
    I wrote a html scraper to scrape my various social identites, so I can make a real time 'biography' website. However after using php curl_exec, I find that texts that I have quoted, end up being formatted in a weird character set. ex: "I love dogs" gets formatted to ’I love dogs ’ "I hate cheese" gets formatted to “I hate cheese� How do I either scrub these characters, or set curl not to format quotes like this. Also, I have turned off magic_quotes.

  • Which is more efficient in mysql, a big join or multiple queries of single table?

    - by Tom Greenpoint
    I have a mysql database like this Post – 500,000 rows (Postid,Userid) Photo – 200,000 rows (Photoid,Postid) About 50,000 posts have photos, average 4 each, most posts do not have photos. I need to get a feed of all posts with photos for a userid, average 50 posts each. Which approach would be more efficient? 1: Big Join select * from post left join photo on post.postid=photo.postid where post.userid=123 2: Multiple queries select * from post where userid=123 while (loop through rows) { select * from photo where postid=row[postid] }

  • Simple way to play a single frequency in java?

    - by alleywayjack
    I just want to play a very simple, straight forward note by giving my computer a certain frequency as an integer, and from there I can figure out how to make it play the note longer or shorter. It does not necessarily have to come out of the actual sound card - if it's generated and output by the internal speaker that's okay. I looked at the midi libraries that java has included, and they are way more than what I want to do. This just needs to be very basic.

  • C# new class with only single property : derive from base or encapsulate into new ?

    - by Gobol
    I've tried to be descriptive :) It's rather programming-style problem than coding problem in itself. Let's suppose we have : A: public class MyDict { public Dictionary<int,string> dict; // do custom-serialization of "dict" public void SaveToFile(...); // customized deserialization of "dict" public void LoadFromFile(...); } B: public class MyDict : Dictionary<int,string> { } Which option would be better in the matter of programming style ? class B: is to be de/serialized externally. Main problem is : is it better to create new class (which would have only one property - like opt A:) or to create a new class derived - like opt B: ? I don't want any other data processing than adding/removing and de/serializing to stream. Thanks in advance!

  • Should I combine unrelated interfaces into a single library?

    - by mafutrct
    Situation is like this: There are independent 5 services. Each service consists of a project for interface, implementation and test. Example: LocalizationService.Interfaces LocalizationService.Implementation LocalizationService.Test There is a WCF service for each of the services: LocalizationService.WcfContract (including DataContracts) LocalizationService.WcfHost The client applications are probably mostly going to use all of the services. Should I combine all service interfaces into a common one? AllServices.AllInterfaces In my opinion, this is a bad idea. The services are independent and there is no reason to introduce a dependency. I imagine that especially testing becomes more difficult. However, one may argue that having to include 5 libraries is too much of a hassle. (I'm not sure how to tag this. Feel free to retag.)
