  • Using Ruby to scan through a string

    - by nekosune
    I am trying to create a regex to gather info from strings that look like this: A22xB67-E34... for any number. I have the regex: @spaceCode = "[A-Z]([A-Z0-9][0-9]|[0-9])" @moveCode=/^(?<one>#{@spaceCode})((?<mode>x|\-)(?<two>#{@spaceCode}))+$/ However I get: s="A11-A22xA33".scan(@moveCode) => [["A11", "11", "xA33", "x", "A33", "33"]] which is most definatly NOT what I want. The string could be any length of C22 etc, with either x or - as the seperator, and put it into an array like: ['A22','x',B22','-'.......] Examples: "A22xB23-D23xE25" => ['A22','x','B23','=','D23','E25;] "AA2xA9-A1" => ['AA2','x','A9','-','A1']

  • PHP: report table with date gaps

    - by Daniel
    Hi. I have a table in DB which contains summaries for days. Some days may not have the values. I need to display table with results where each column is a day from user selected range. I've tried to play with timestamp (end_date - start_date / 86400 - how many days in report, then use DATEDIFF(row_date, 'user_entered_start_date') and create array from this indexes), but now I've got whole bunch of workarounds for summer time :( Any examples or ideas how to make this correct? P.S. I need to do this on PHP side, because DB is highly loaded.

  • Java exception translations

    - by user3079275
    Apologies if this has been discussed on other threads but I find it helps clarify my thinking when I am forced to write down my questions. I am trying to properly understand the concept of checked vs unchecked exceptions and exception translation in Java but I am getting confused. So far I understood that checked exceptions are exceptions that need to be always caught in a try/catch block otherwise I get a compile time error. This is to force programmers to think about abnormal situations that might happen at run time (like disk full etc). Is this right? What I did not get was why we have unchecked exceptions, when are they useful? Is it only during development time to debug code that might access an illegal array index etc? This confusion is because I see that Error exceptions are also unchecked as is RunTimeException but its not clear to me why they are both lumped together into an unchecked category?

  • Getting time from a cell in Google Spreadsheet

    - by lostInTransit
    Hi I have created a Google Spreadsheet form in which for one of the fields I get the time (hh:mm:ss) in 24-hour format. I am using Google Apps Scripts to read values from this spreadsheet and put it into another file. But the other file gets the entire date (don't know from where) and shows a date from 1899. Also the time is shown in PDT (not my time zone). Even the time it prints is not correct How do I read the column value as a string and put it in the other file OR get just the time from the column value (and the correct time) I am using a simple row[0][3] to get the values from an array after doing range.getValues() Thanks.

  • Magento get loaded collection

    - by Zertalx
    Hey guys I got an issue in magento when listing products. $_productCollection = array(); $key = 'product_collection_'.Mage::app()->getRequest()->getRequestUri(); $_productCollection = Mage::helper('cache')->getDataInCache($key); if (empty($_productCollection)) { $_productCollection=$this->getLoadedProductCollection(); Mage::helper('cache')->setDataInCache($key,$_productCollection,'front_end_collection'); } That's my code, i'm loading the collection and saved in cache, the problem is that I added new products from the admin panel but they are not showing up in the listing. I have refreshed cache, reindex all the data and checke that the products were in stock. Also check the visibility because i understand that the collection gets just the visible products, am i correct? I'm using magento enterprise 1.9 I'm new in magento and i'm having troubles understanding how the Collections works, i hope somebody can help me. Thanks

  • Strings - Filling In Leading Zeros Wtih A Zero

    - by headscratch
    I'm reading an array of hard-coded strings of numeric characters - all positions are filled with a character, even for the leading zeros. Thus, can confidently parse it using substring(start, end) to convert to numeric. Example: "0123 0456 0789" However, a string coming from a database does not fill in the leading zero with a 'zero character', it simply fetches the '123 456 789', which is correct for an arithmetic number but not for my needs and makes for parsing trouble. Before writing conditionals to check for leading zeros and adding them to the string if needed, is there a simple way of specifying they be filled with a character ? I'm not finding this in my Java book... I could have done the three conditionals in the time it took to post this but, this is more about 'education'... Thanks

  • public (static) swap() method vs. redundant (non-static) private ones...

    - by Helper Method
    I'm revisiting data structures and algorithms to refresh my knowledge and from time to time I stumble across this problem: Often, several data structures do need to swap some elements on the underlying array. So I implement the swap() method in ADT1, ADT2 as a private non-static method. The good thing is, being a private method I don't need to check on the parameters, the bad thing is redundancy. But if I put the swap() method in a helper class as a public static method, I need to check the indices every time for validity, making the swap call very unefficient when many swaps are done. So what should I do? Neglect the performance degragation, or write small but redundant code?

  • How to understand the output of the PHP regex matching below?

    - by smarty
    $file = '{include file="{$COMMON_TPL_PATH}common/header_admin.tpl"} {include file="{$mainPage}"} {include file="{$COMMON_TPL_PATH}common/footer_admin.tpl"}'; preg_match('/^(\{\})|^(\{\*([\S\s]*?)\*\})|^(<\?(?:php\w+|=|[a-zA-Z]+)?)|^([ ]*[ ]+[ ]*)|^(\{strip\})|^(\{\/strip\})|^(\{literal\})|^(\{\s{1,}\/)|^(\{\s{1,})|^(\{\/)|^(\{)|^(([\S\s]*?)(?=([ ]*[ ]+[ ]*|\{|<\?)))|^([\S\s]+)/', $file, $matches); var_dump($matches); Why the output is: array(13) { [0]=> string(1) "{" [1]=> string(0) "" [2]=> string(0) "" [3]=> string(0) "" [4]=> string(0) "" [5]=> string(0) "" [6]=> string(0) "" [7]=> string(0) "" [8]=> string(0) "" [9]=> string(0) "" [10]=> string(0) "" [11]=> string(0) "" [12]=> string(1) "{" } It seems to me that ^([\S\s]+) can match the whole string..

  • C# how to store those information?

    - by 5YrsLaterDBA
    I have a PrivilegeGroup table, a Privileges table and a link table because the PrivilegeGroup table and the Privileges table is a many to many relationship. I am thinking about load all contents of PrivilegeGroup table and Privilege table into memory from database at beginning when application started. I want to save them in a form easily to look up. Usually we will look up the PrivilegeCode via GroupId. Which structure is good for this purpose? array of list? dictionary?

  • Controlling Too Many listboxes ( C#)

    - by Ases
    I have almost 200 listboxes. I'm changing their visibility according to my variables from database. So I thought that, I prepared a arraylist. like this ListBox[] lbs = this.Controls.OfType<ListBox>().ToArray(); And used like this. for (int idx = 0; idx < Convert.ToInt32(ds.Tables[j].Rows[i][2])*12; idx++) lbs[idx].Visible = true; This codes are written to comboboxchange. Now everything is okay. But; example; first time I changed combobox 1-20 listboxes visible=true I changed combobox again not 1-20. 20,40 changing :S How can it be, can u tell me an alternative array list type, or another way?

  • php string search - grabbing specific urls

    - by MEM
    Hello, I have this string that may contain some urls that I need to grab. For instance, if the user does: www.youtube ... or www.vimeo ... or http://www.youtube ... or HttP://WwW.viMeo I need to grab it (until he finds a space perhaps). and store it on a already created array. The need is to separate the vimeo links from the youtube ones and place each of those on the appropriate video object. I'm not sure if this is possible, I mean, if the URL coming from the browser could be used to be placed on a predefined video object. If it is, then this is the way to go (so I believe). If all this is feasible, can I have your help in order to build such a rule? Thanks in advance

  • Actionscript 3.0 Get all instances of a class?

    - by Windbrand
    I got a ton of movieclips in a class. Is there a more efficient way to apply a function to every instance in the class other than this? var textArray:Array = [ interludes.interludeIntro.interludeBegin1, interludes.interludeIntro.interludeBegin2, interludes.interludeIntro.interludeBegin3, interludes.interludeIntro.interludeBegin4, interludes.interludeIntro.interludeBegin5, interludes.interludeIntro.interludeBegin6, interludes.interludeIntro.interludeBegin7, //... ... ... interludes.interludeIntro.interludeBegin15 ]; for each (var interludeText:MovieClip in interludeBeginText) { interludeText.alpha = 0 //clear all text first } Also for some reason this doesn't work: interludes.interludeIntro.alpha = 0; It permanently turns that class invisible, even if I try to make specific instances visible later with: interludes.interludeIntro.interludeBegin1.alpha = 1; I have NO idea why the above doesn't work. I want to turn every single instance in the class interludeIntro invisible, but I want to turn specific instances visible later. (btw I have no idea how to insert code on this website, pressing "code" doesn't do anything, so pardon the bad formatting)

  • Trying to understand the Zend_Auth OpenId

    - by Will Olbrys
    I'm using a slightly modified version of the Zend_Auth_OpenId classes to get openid logins from google apps. The results are very positive, as I seem to be getting successful results from Google. I cannot get successful results passed to Zend_Auth, though. For example, Zend_Auth_Adapter_OpenId on line 241: if (!$consumer->login($id, $this->_returnTo, $this->_root, $this->_extensions, $this->_response)) { return new Zend_Auth_Result( Zend_Auth_Result::FAILURE, $id, array("Authentication failed", $consumer->getError())); } The consumer calls login() which in turn calls the private method _checkId() in Zend_OpenId_Consumer. _checkId() always ends in redirecting to the openid server. How is this ever supposed to return a valid Zend_Auth_Result object? I'm pretty close to giving up and trying to implement another OpenId library, but I'm so close to just making this work. I must be missing something so obvious! Maybe I don't understand how openid works exactly, but if someone could help me understand I would really appreciate it.

  • C++ function for picking from a list where each element has a distinct probability

    - by Stuart
    I have an array of structs and one of the fields in the struct is a float. I want to pick one of the structs where the probability of picking it is relative to the value of the float. ie struct s{ float probability; ... } sArray s[50]; What is the fastest way to decide which s to pick? Is there a function for this? If I knew the sum of all the probability fields (Note it will not be 1), then could I iterate through each s and compare probability/total_probability with a random number, changing the random number for each s? ie if( (float) (rand() / RAND_MAX) < probability)...

  • Do I need to declare all my JQuery prototypes in a JQueryStatic definition file with typescript?

    I have the following code: ///<reference path="../typescript/jquery.d.ts" /> function addThemePrototypes() { var templateSetup = new Array(); $.fn.addTemplateSetup = function(func, prioritary) { if (prioritary) { templateSetup.unshift(func); } else { templateSetup.push(func); } }; } When I try to add the following: $('a').addTemplateSetup( Into this same file I notice there is no intellisense and typescript does not seem to know about the addTemplateSetup prototype that I just added. Is this the correct way for it to work or do I always need to add things like the definition for addTemplateSetup to an JQueryStatic definition file and then include that?

  • iOS sdk question: how do I cast a UIView to a UIImage View (alternativly how do I get a UIImageView from a GestureRecognzer?)

    - by user439299
    Desired end result: user taps a UIImageView and the image changes to another image (a subsequent tap returns the image to the original state) Problem: I add a (unique) selector to a bunch of UIImageViews (in an array) and point the action at the same function - let's call this function imageTapped: for now. Here is my code so far: -(void)imageTapped:(UITapGestureRecognizer *)tapGesture { UIImageView *view = tapGesture.view; // rest of code... } This code actually works fine but gets a warning when I run it: "Incompatible objective c types initilizing 'struct UIView *', expected 'struct UIImageView *' Any way to get rid of this? Not sure how casting works in objective c... primitive types seem to work fine such as (int)someFloat works fine but (UIImageView)someUiView doesn't work. Like I said, code works alright when I run it but would like to get ride of the compiler warning. Any help would be awesome.... I am very new to objective c (or any non java language for that matter) so be gentle. Thanks in advance.

  • Empty files generated from running `mysqldump` using PHP

    I keep getting empty files generated from running $command = 'mysqldump --opt -h localhost -u username -p \'password\' dbname > \'backup 2009-04-15 09-57-13.sql\''; command($command); Anyone know what might be causing this? My password has strange characters in it, but works fine with connecting to the db. I've ran exec($command, $return) and outputted the $return array and it is finding the command. I've also ran it with mysqldump > file.sql and the file contains Usage: mysqldump [OPTIONS] database [tables] OR mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...] OR mysqldump [OPTIONS] --all-databases [OPTIONS] For more options, use mysqldump --help So it would seem like the command is working.

  • What does it mean when a Perl method returns a "hashref"?

"\n"; } I'm Puzzled by each operator on the first line. What type exactly are $response, $respone->{bucket}. Looks like the expression within the for is an array, but I don't understand this syntax: @{ ... }?
