  • Removing HTML from a Java String

    - by Mason
    Is there a good way to remove HTML from a Java string? A simple regex like replaceAll("\\<.*?>","") will work, but things like &amp; wont be converted correctly and non-HTML between the two angle brackets will be removed (ie the .*? in the regex will disappear).

  • How to checking wether an object has a specific method or not

    - by Ghommey
    Hey, I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell wether $myObject has a method called helloWorld or not?

  • Get current Apache version string for display

    - by Stijn Sanders
    I'm writing an Apache module and want to get a string with the Apache name version and other details. Much like what gets added to outgoing headers, e.g.: Server: Apache/2.2.13 (Win32) I've tried code like this: apr_table_get(request_rec->headers_out,"Server") But that doesn't seem to work. Is there an API call I haven't found or am I doomed to get version resource data from httpd.exe?

  • C++ problem with string stream istringstream

    - by user69514
    I am reading a file in the following format 1001 16000 300 12.50 2002 24000 360 10.50 3003 30000 300 9.50 where the items are: loan id, principal, months, interest rate. I'm not sure what it is that I am doing wrong with my input string stream, but I am not reading the values correctly because only the loan id is read correctly. Everything else is zero. Sorry this is a homework, but I just wanted to know if you could help me identify my error. if( inputstream.is_open() ){ /** print the results **/ cout << fixed << showpoint << setprecision(2); cout << "ID " << "\tPrincipal" << "\tDuration" << "\tInterest" << "\tPayment" <<"\tTotal Payment" << endl; cout << "---------------------------------------------------------------------------------------------" << endl; /** assign line read while we haven't reached end of file **/ string line; istringstream instream; while( inputstream >> line ){ instream.clear(); instream.str(line); /** assing values **/ instream >> loanid >> principal >> duration >> interest; /** compute monthly payment **/ double ratem = interest / 1200.0; double expm = (1.0 + ratem); payment = (ratem * pow(expm, duration) * principal) / (pow(expm, duration) - 1.0); /** computer total payment **/ totalPayment = payment * duration; /** print out calculations **/ cout << loanid << "\t$" << principal <<"\t" << duration << "mo" << "\t" << interest << "\t$" << payment << "\t$" << totalPayment << endl; } }

  • An object reference is required for the non-static field, method, or property using global variable

    - by Jose Cardama
    Hello Iam working in a global int in which a variable will be used later. I've made the global variable like this: class Foo { public static int stream = Bass.BASS_StreamCreateFile(path1.Text, 0, 0, BASSFlag.BASS_DEFAULT); } which will be later called like this: Foo.stream and it can also contain more then 1 stream for example stream20,30,etc... The problem here is that it returns me this error: "An object reference is required for the non-static field, method, or property" where I call the text in path1.Text How do I fix this?

  • [C++] STL list - how to find a list element by its object fields

    - by Dominic Bou-Samra
    I have a list: list<Unit *> UnitCollection; containing Unit objects, which has an accessor like: bool Unit::isUnit(string uCode) { if(this->unitCode == uCode) return true; else return false; } How do I search my UnitCollection list by uCode and return the corresponding element (preferably it's index). I have looked at the find() method, but i'm not sure you can pass a boolean method in instead of a searched item parameter if that makes sense.

  • Oracle - Return shortest string value in a set of rows

    - by Sridhar
    Hi, I'm trying to write a query that returns the shortest string value in the column. For ex: if ColumnA has values ABCDE, ZXDR, ERC, the query should return "ERC". I've written the following query, but I'm wondering if there is any better way to do this? BTW, the query should return a single value. select distinct ColumnA from ( select ColumnA, rank() over (order by length(ColumnA), ColumnA) len_rank from TableA where ColumnB = 'XXX' ) where len_rank <= 1 Thank you.

  • PHP - Check for whitespace at beginning of string

    - by ITg
    I need to use preg_match to check that only a-z0-9. is used (including full stop(.)). I don't want to replace anything. My problem is that it doesn't notice white space at beginning of a string. Also, if anyone knows how to check there is no two full stops in a row, I would be very grateful. What I have so far: ("/[^a-z0-9.]+$/",$request) Thanks !

  • What is the role of the Router Object in MVC based frameworks

    - by Saif Bechan
    In most MVC based framework I see a router object. If I look at it splits up the uri and decides what controller should be used, and which action should be fired. Even though this makes a lot of sense, I can not give this a place in the MVC patern. Is splitting up the uri not the job of the controller. And then the controller should just decide which class and function to run.

  • Modifying the Codec List Object in an ASF file

    - by scompt.com
    Is it possible to modify the Codec List Object in an ASF file? In particular, I would like to edit the codec name and description. I realize that this won't actually change the content of the video, but it's necessary for the video to be verified by an external tool. Does anyone know of a tool that will allow me to do this? If not, does anyone have any suggestions about how I might go about doing it using the Windows Media Format 11 SDK?

  • Extract two double Values from String using RegEx in Java

    - by tzippy
    I am reading a file by line and need to extract latitude and longitude from it. This how lines can looks: DE 83543 Rott am Inn Bayern BY Oberbayern Landkreis Rosenheim 47.983 12.1278 DE 21147 Hamburg Hamburg HH Kreisfreie Stadt Hamburg 53.55 10 What's for sure is, there are no dots surrounded by digits except for the ones representing the doubles. Unfortunately there are Values without a dot, so it's probably best to check for numbers from the end of the String. thanks for your help!

  • LinkedList insert tied to inserted object

    - by wrongusername
    I have code that looks like this: public class Polynomial { List<Term> term = new LinkedList<Term>(); and it seems that whenever I do something like term.add(anotherTerm), with anotherTerm being... another Term object, it seems anotherTerm is referencing the same thing as what I've just inserted into term so that whenever I try to change anotherTerm, term.get(2) (let's say) get's changed too. How can I prevent this from happening?
