  • How to check if string is a valid XML element name?

    - by xsaero00
    I need a regex or a function in PHP that will validate a string to be a good XML element name. Form w3schools: XML elements must follow these naming rules: Names can contain letters, numbers, and other characters Names cannot start with a number or punctuation character Names cannot start with the letters xml (or XML, or Xml, etc) Names cannot contain spaces I can write a basic regex that will check for rules 1,2 and 4, but it won't account for all punctuation allowed and won't account for 3rd rule \w[\w0-9-]

  • What operation type invoked a trigger in SQL Server 2008?

    - by Neil Moss
    I'm contemplating a single SQL trigger to handle INSERT, UPDATE and DELETE operations as part of an auditing process. Is there any statement, function or @@ variable I can interrogate to find out which operation type launched the trigger? I've seen the following pattern: declare @type char(1) if exists (select * from inserted) if exists (select * from deleted) select @Type = 'U' else select @Type = 'I' else select @Type = 'D' but is there anything else a little more direct or explicit? Thanks, Neil.

  • How can we detect hotkeys registered by other apps?

    - by worlds-apart89
    Is it possible to detect all the hotkeys registered by the OS as well as software applications currently running? Any native or managed approach on the Windows platform? I know that the RegisterHotKey function returns false if the hotkey is already registered, but what I am looking for is an approach, method, etc. that will give me a list of registered hotkeys. Looping all possible combinations with RegisterHotKey does not sound like a good idea. Anything more efficient?

    - by mvid
    I am attempting to have mechanize select a form from a page, but the form in question has no "name" attribute in the html. What should I do? when I try to use br.select_form(name = "") i get errors that no form is declared with that name, and the function requires a name input. There is only one form on the page, is there some other way I can select that form?

Basic requirements of site: Users can submit text entries - generally 1 liners Enters can be up or down voted Comments allowed - presentation collapseable Would like the fastest path possible. Ideal solution is configurable vs requirement for programming.

  • Corner Cases, Unexpected and Unusual Matlab

    - by Mikhail
    Over the years, reading others code, I encountered and collected some examples of Matlab syntax which can be at first unusual and counterintuitive. Please, feel free to comment or complement this list. I verified it r2006a. set([], 'Background:Color','red') Matlab is very forgiving sometimes. In this case, setting properties to an array of objects works also with nonsense properties, at least when the array is empty. myArray([1,round(end/2)]) This use of end keyword may seem unclean but is sometimes very handy instead of using length(myArray). any([]) ~= all([]) Surprisigly any([]) returns false and all([]) returns true. And I always thought that all is stronger then any. EDIT: with not empty argument all() returns true for a subset of values for which any() returns true (e.g. truth table). This means that any() false implies all() false. This simple rule is being violated by Matlab with [] as argument. Loren also blogged about it. Select(Range(ExcelComObj)) Procedural style COM object method dispatch. Do not wonder that exist('Select') returns zero! [myString, myCell] Matlab makes in this case an implicit cast of string variable myString to cell type {myString}. It works, also if I would not expect it to do so. [double(1.8), uint8(123)] => 2 123 Another cast example. Everybody would probably expect uint8 value being cast to double but Mathworks have another opinion. a = 5; b = a(); It looks silly but you can call a variable with round brackets. Actually it makes sense because this way you can execute a function given its handle. a = {'aa', 'bb' 'cc', 'dd'}; Surprsisingly this code neither returns a vector nor rises an error but defins matrix, using just code layout. It is probably a relict from ancient times. set(hobj, {'BackgroundColor','ForegroundColor'},{'red','blue'}) This code does what you probably expect it to do. That function set accepts a struct as its second argument is a known fact and makes sense, and this sintax is just a cell2struct away. Equvalence rules are sometimes unexpected at first. For example 'A'==65 returns true (although for C-experts it is self-evident). About which further unexpected/unusual Matlab features are you aware?

  • Starting inets/httpd with custom application

    - by williamstw
    I've got a module that I'm attempting to turn into a proper OTP application. Currently, the module has start/0 which starts a genserver which supplies configuration data read from a config file. It then calls inets:start(httpd,config:lookup(httpd_conf)). I gather that I need to move the starting of these out into the .app file's (application list) but I'm not sure how to get my config data into the inets:start function (or pass in httpd)? Thanks, --tim

  • Ab Initio - Formatting a number in Left alignment

    - by Veera
    I have a requirement in Ab Initio to format a number in left alignment. I shouldn't be using String conversion (as Strings are left aligned by default), as it might cause compatibility problems in the other end. For example, if my Field has 7 bytes length, and I'm getting only two digits as my input, then these two digits should go into the first two bytes of my field (left aligned), instead of the last two bytes. So, is there any in-built function in Ab Initio, that can format a number as left aligned?

  • Good alternative to Eregi() in PHP

    - by Click Upvote
    I often find myself doing quick checks like this: if (! eregi('.php',$fileName)) $filename.='.php'; But sadly eregi() is going to be deprecated in PHP 6, which means all of my code that uses it will be rendered useless :(. Is there another function that behaves exactly the same way as eregi()? I don't know anything about reg exps and don't want to learn, so preg_match() etc won't work for me.

  • C++: How to extract a string from rapidxml

    - by hamishmcn
    In my C++ program I want to parse a small piece of XML, insert some nodes, then extract the new XML (preferably as a std::string) RapidXML (http://rapidxml.sourceforge.net/) has been recommended to me, but I can't see how to retrieve the XML back as a text string. (I could iterate over the nodes and attributes and build it myself, but surely there's a build in function that I am missing) Thank you

  • Visual Studio Add in.

    I was looking to write/get a visual studio add in. I want to be able to write descriptive log calls at the top and bottom of a function. like this log.debug("TheClass.TheMethod(string TheStringParam ="+TheStringParam+") - in"); log.debug("TheClass.TheMethod(string TheStringParam ="+TheStringParam+") - out"); Is there an adin that does this? Is there source anywhere for an add in like Ghost Doc that does reflection(or whatever) to parse the parameters and such? Thanks, Eric-

  • how to find selected elements with Jquery UI selectable

    - by kevzettler
    Hi All, I am looking for info on the event and ui objects the jquery selectable events: "selecting", and "start" take as parameters. I cannot find this in the documentation and looping through the properties is no help. $('#content_td_account').selectable({ filter: 'li:not(".non_draggable")', selecting: function(event, ui) { } }); Specifically I want to find what elements are being selected and check them to see if their parent elements are the same or not. I assumed this would be in the ui object some where.
