  • any character notation for php regular expression

    - by Mith
    In my regex, I want to say that within the sample text, any characters are allowed, including a-z in upper and lower case, numbers and special characters. For example, my regular expression may be checking that a document is html. therefore: "/[]+/" i have tried []+ but it does not seem to like this?

  • How to test if a gawk string contain a number?

    - by Tim Menzies
    In gawk I know two ways to test if a string contains a number. Which is best? Method one: using regular expressions: function method1(x) { return x ~ /^[+-]?([0-9]+[.]?[0-9]*|[.][0-9]+)([eE][+-]?[0-9]+)?$/ } Method two: the coercion trick (simpler): function method2(x) { return (x != "") && (x+0 == x) } Is there any reason to favor the more complex method1 over the simpler method2?

  • CODE1 Spoj - cannot solve it

    - by VaioIsBorn
    I am trying to solve the problem Secret Code and it's obviously math problem. The full problem For those who are lazy to go and read, it's like this: a0,a1,a2,...,an - sequence of N numbers B - some number known to us X = a0 + a1*B + a2*(B^2) + a3*(B^3) + ... + an*(B^n) So if you are given B and X, you should find a0,a1,..an. I don't know how or where to start, because not even N is known, just X and B. Can you help me ?

  • Get Criteria by associationPath

    - by niklassaers
    Hi guys, Every so often, I get a "org.hibernate.QueryException: duplicate association path: myAssociation". This is because the complex criteria I'm working with can define the same path in many places. I'd love to do something like Criteria association = myCriteria.getAssociation("wax"); if(association == null) association = myCriteria.createCriteria("wax"); Is there any such way that I can check if an association is already in place? Cheers Nik

  • Mathematica equivalent of Ruby's inject

    - by Ben Alpert
    Is there a Mathematica function like inject in Ruby? For example, if I want the product of the elements in a list, in Ruby I can write: list.inject(1) { |prod,el| prod * el } I found I can just use Product in Mathematica: Apply[Product, list] However, this isn't general enough for me (like, if I don't just want the product or sum of the numbers). What's the closest equivalent to inject?

  • PHP 5.2 Function needed for GENERIC sorting of a recordset array

    - by donbriggs
    Somebody must have come up with a solution for this by now. We are using PHP 5.2. (Don't ask me why.) I wrote a PHP class to display a recordset as an HTML table/datagrid, and I wish to expand it so that we can sort the datagrid by whichever column the user selects. In the below example data, we may need to sort the recordset array by Name, Shirt, Assign, or Age fields. I will take care of the display part, I just need help with sorting the data array. As usual, I query a database to get a result, iterate throught he result, and put the records into an assciateiave array. So, we end up with an array of arrays. (See below.) I need to be able to sort by any column in the dataset. However, I will not know the column names at design time, nor will I know if the colums will be string or numeric values. I have seen a ton of solutions to this, but I have not seen a GOOD and GENERIC solution Can somebody please suggest a way that I can sort the recordset array that is GENERIC, and will work on any recordset? Again, I will not know the fields names or datatypes at design time. The array presented below is ONLY an example. UPDATE: Yes, I would love to have the database do the sorting, but that is just not going to happen. The queries that we are running are very complex. (I am not really querying a table of Star Trek characters.) They include joins, limits, and complex WHERE clauses. Writing a function to pick apart the SQL statement to add an ORDER BY is really not an option. Besides, sometimes we already have the array that is a result of the query, rather than the ability to run a new query. Array ( [0] => Array ( [name] => Kirk [shrit] => Gold [assign] => Bridge ) [1] => Array ( [name] => Spock [shrit] => Blue [assign] => Bridge ) [2] => Array ( [name] => Uhura [shrit] => Red [assign] => Bridge ) [3] => Array ( [name] => Scotty [shrit] => Red [assign] => Engineering ) [4] => Array ( [name] => McCoy [shrit] => Blue [assign] => Sick Bay ) )

  • Changing the style of a Combo-Box in WPF (in Blend preferably)

    - by George Sealy
    I'm having some issues trying to change the look / style of a combo box in Expression Blend / WPF. While there are tutorials out there describing setting styles for buttons, there seem to be a few wrinkles with ComboBox controls. Can anyone offer any advice, or point me towards good tutorials that cover re-styling something more complex than a button?

  • Debugging php-cli scripts with xdebug and netbeans?

    - by wurdalack
    I have managed to initiate php-cli script debug session from the IDE itself, but I need to start the debugging session from the shell / command line. These are rather complex maintenance PHP scripts which take a lot of input parameters, so entering arguments from within Netbeans is a bit cumbersome. I have done it before with Zend studio http://kb.zend.com/index.php?View=entry&EntryID=130 but now I need to get it working with Netbeans. Thanks in advance.

    Hi, I would like to overload the (/) operator in F# for strings and preserve the meaning for numbers. /// Combines to path strings let (/) path1 path2 = Path.Combine(path1,path2) let x = 3 / 4 // doesn't compile If I try the following I get "Warning 29 Extension members cannot provide operator overloads. Consider defining the operator as part of the type definition instead." /// Combines to path strings type System.String with static member (/) (path1,path2) = Path.Combine(path1,path2) Any ideas?
