I recently wanted to use boost::algorithm::join but I couldn't find any usage examples and I didn't want to invest a lot of time learning the Boost Range library just to use this one function. Can anyone provide a good example of how to use join on a container of strings? Thanks. ...
I see a lot of legacy code like this: class A { public static final String CONSTANT = "value".intern(); ... } I don't see any reason for the intern(), as in the Javadoc one can read: "All literal strings and string-valued constant expressions are interned." Is there some intent of this, maybe in past revisions of the language?...

I have three integers: ($r, $g, $b) = (255, 128, 0); I would like to print a string like: "#FF8000" using those variables. How do I do this? ...
My strongly typed View inherits from a "Person" object that is created with Linq to SQL. In my "Edit" View, i have to display of course old values: <%= Html.TextBox("FirstName") %> "FirstName" is NCHAR, so it need to be trimmed. So i ended up with: <%= Html.TextBox("FirstName", Model.FirstName.Trim()) %> and this works. But when fo...
Somehow I managed to stick Ôªø at the top of a PHP script. What is that horrifying group of characters, how could I have entered it, and how can I expose and/or avoid it in the future? Anecdotally, it was lurking at the very top of a PHP script, before <?php. The script needed to send a Content-type header. Because Ôªø pushed the header...
In Python 3.x, a string consists of items of Unicode ordinal. (See the quotation from the language reference below.) What is the internal representation of Unicode string? Is it UTF-16? The items of a string object are Unicode code units. A Unicode code unit is represented by a string object of one item and can hold either a ...

I cant use complicated code in html like <? $i = 0 ;?> <? foreach($tst as $test) : ?> <?=$test->id?>, <? endforeach ?> <? $i++ ;?> <? if($i != co...
I have a byte offset for a byte array containing a UTF-8 encoded string, how can I transform that into a char offset for the corresponding Java String? NB. this question used to read: I have a byte offset into a standard Java String, and I would like to convert that to a character offset. In practice this will mean a method like charO...
Greetings to the enlightened ones! I'm playing on this for several hours now, but wasn't successful (perhaps because I'm quite new to WPF): I have a DataGrid whose DataContext is bound to a DataTable. The DataGrid is of fixed size and its purpose is to hold a value table y(x) (i.e. the headers show the x-values and the corresponding y-...
In an C# ASP.Net MVC project, I'm trying to make a List<string> from a LINQ variable. Now this might be a pretty basic thing, but I just cannot get that to work without using the actual column names for the data in that variable. The thing is that in the interests of trying to make the program as dynamic as possible, I'm leaving it up t...
Hi, is there any STL algorithm or a standard way of finding how many occurences of particular substring are there in a string? For example in string: 'How do you do at ou' the string "ou" appears twice. I tried some STL algorithms with and without predicates but what I found is that those algorithms from STL want to compare components...
Is it possible to specify some kind of flag or modifier to a string format param to customize it, something like the number formating flags? Example of want I want: String.Format("Hi {0:touppercase}, you have {1} {2:tolowercase}.", "John", 6, "Apples"); Wanted output: Hi JOHN, you have 6 apples. PS: Yes I know that I can change the ...
I'm looking to optimized this piece of code. It will process 15000 - 20000 lines. For now I have 9000 lines and it take 30 sec approx. I know string concatenation is slow but I don't know how to do it another way. // // Check if composite primary keys existe in database // ...
Hi, I have an Access application where everytime a user enters the application, it makes a temp table for that user called 'their windows login name'_Temp. In one of my reports I need to query using that table, and I can't just make a query and set it as the recourdsource of the report, since the name of the table is always different. ...
I normally create a String in Java the following way: String foo = "123456"; However, My lecturer has insisted to me that forming a String using the format method, as so: String foo = String.format("%s", 123456); Is much faster. Also, he says that using the StringBuilder class is even faster. StringBuilder sb = new StringBuilde...
Imagine you're dealing with many strings of text that are about 10,000 characters long entered by users. Would it be more efficient to write those automatically onto pages or input them onto a table in a database? I hope that question is clear enough... ...
I want to scrape string data from some binary text files that contain embedded SQL statements. I don't need any fancy cleanup--just some way to extract the readable text. I'm using vb.net, but a call to an external utility would work too. ...
