I want my output to be Candy[1]. counterInt = 1 But my compiler isn't taking this code: System.out.println("Candy["+counterInt"]"); What can I do to have this variable appear within the string Candy[]? Candy[] is not an array, it's a string. ...
How do I do this in MySQL? SELECT * FROM MyTable WHERE MyDateCol < TODAY() I googled a lot on the subject and didn't really find anything except "look in the MySQL date ref" which does not explain the above easily enough. I know I can do the following which is kinda indirect: SELECT * FROM MyTable WHERE MyDateCol BETWEEN (0000-00-0...
In ruby 1.9 there is a way to define this hash with the new syntax? irb> { a: 2 } => {:a=>2} irb> { a-b: 2 } SyntaxError: (irb):5: syntax error, unexpected tLABEL { a-b: 2 } ^ with the old one, it's working: irb> { :"a-b" => 2 } => {:"a-b"=>2} ...
Aside from adding a method explicitly on the subclass to call a super method, is there anyway to "unhide" it temporarily? I would like to call the super.blah() method on a Test2 instance. Must I use a method like originalBlah, or is there another way? public class TestingHiding { public static void main(String[] args) { Test...
I have the following CSS: .foo .bar { background: red; } Which works fine for the following HTML: <div class="foo"> <div class="bar">I have a red background</div> </div> But I can't seem to find a way to reuse the CSS definition when I'm not in a parent/child relationship. For example, how could I apply the same CSS to the f...
I have some problem with this jQuery code. I'm new at this but it works in FF and yet breaks in Chrome and Safari. Grateful for suggestions in any way. $('#level1nav ul li a:last').click(function () { $(lastBlock).animate({height:"400px"}, {queue:false, duration:500, complete: function() $(line).animate({width:"0px"}, ...
Toying with heredocs in PHP, I realized the name of the heredoc does not have to be unique. Thus: $a = <<<EOD Some string EOD; $b = <<<EOD A different string EOD; is correct and behaves exactly as you would expect. Is this bad practice for any reason? Why does a heredoc need a name/label (EOD above) at all, since you can't referen...
any idea how I can pass correct argument to xpath? There must be something about how to use single/double quotes. When I use variable parser_xpath_identificator = "'//table/tbody[@id=\"threadbits_forum_251\"]/tr'" gives me an incorrect value or parser_xpath_identificator = "'//table/tbody[@id="threadbits_forum_251"]/tr'" gives me an ...
Code in Bugzilla templates is usually delimited by [% and %]. But sometimes I see [%+ and [%-. Can someone explain the difference or point me at suitable documentation? Google has failed me on this occasion. For example: [%- event.value.subject FILTER html %] or [%+ END %] ...
If i run every block of this script in mysql-query-browser, it works. If i run it as mysql db < script.sql it gives me an error[1] that the documentation says it's for using reserved keywords. Already tried to use ; everywhere. -- table CREATE TABLE `days` ( `day` date NOT NULL, PRIMARY KEY (`day`) ) ENGINE=MyISAM DEFAULT CHARSE...
I'd like to have vim highlight entire lines that match certain patterns. I can get all the text in a line to highlight (by doing syn match MyMatch "^.*text-to-match.*$"), but it always stops at the end of the text. I'd like to to continue to the end of the term, like highlighting CursorLine. I've tried replacing $ with a \n^, hoping t...
Usually I create a new object invocating his constructor the usual way: $instance= new Class(); Lately, I'm reading a lot of code with an alternative syntax (without the parentesys): $instance= new Class; There are substantial differences between the two methods or are they equivalent? I haven't found references on this topic 'til...
I want to make my variable (a proxy object) evaluate to false when used in conditional sentences. I know I can use .nil? and even var == nil but I think that's not good enough. What I am trying go do is to: if myproxy # not only myprroxy.nil? or myproxy == nil, but just that # myproxy's backend object is not nil else # myproxy's bac...
What is the meaning of == and how does it differ from =? How do I know which one to use? And how can I type the two vertical lines for the OR logical operator? ...
Say I have a field on a datawindow that is the value of a database column ("Insert > Column). It has conditions in which it needs to be protected (Properties>General>Protect). I want to have the field background grey when it's protect. At the moment, the only way I can work out how to do this is to copy the protect conditional, no matte...
BASIC and its variants Visual Basic and VB.NET are the only programming languages I know of that treat the end of line character as a statement terminator (I'm excluding batch files and command scripts from the domain of programming languages). I'm curious: is there any other language that uses this convention, or does BASIC stand alone...
A discussion in another thread got me wondering: what do other programming languages' exception systems have that Perl's lacks? Perl's built-in exceptions are a bit ad-hoc in that they were, like the Perl 5 object system, sort-of bolted on as an afterthought, and they overload other keywords (eval and die) which are not dedicated specif...
I've been attempting to follow the instructions on the Vim wiki to get the matchit plugin working with ColdFusion (*.cfm) files containing both ColdFusion and HTML tags running on MacVim. I've got the syntax file for ColdFusion (cf.vim) installed in $HOME/.vim/syntax/cf.vim, the latest version of matchit installed in .vim/plugin/matchit...
So I've just about finished my first F# program, with my only functional background being a little bit of knowledge of Haskell (read: Haven't really produced any programs in it). After experiencing some boggling behavior, I came to realize that F# makes a differentiation between: prepareDeck = allSuits |> List.collect generateCards |> ...
Latelly I've seen a lot of PHP/MySQL questions that enclose SQL values within {}, for instance: SELECT * FROM table WHERE field LIKE '{$value}'; What's up with that? Is it even valid? Why do so many people use this weird (at least for me) syntax? ...
