  • Parsing plain data with Javascript (JQuery)

    - by Angelus
    Well , I have this text in a Javascript Var: GIMP Palette Name: Named Colors Columns: 16 # 255 250 250 snow (255 250 250) 248 248 255 ghost white (248 248 255) 245 245 245 white smoke (245 245 245) 220 220 220 gainsboro (220 220 220) 255 250 240 floral white (255 250 240) 253 245 230 old lace (253 245 230) 250 240 230 linen (250 240 230) 250 235 215 antique white (250 235 215) 255 239 213 papaya whip (255 239 213) And What I need is to cut it in lines and put them in one Array , after that i must separate each number and the rest in an string. I'm getting crazy searching functions to do that but now i can't see anyone in Javascript. modified End expected format will be first the next: array[0]='255 250 250 snow (255 250 250)' Then i wanna take it and extract each line into some vars to use them: colour[0]=255; colour[1]=250; colour[2]=250; string=snow (255 250 250); (the vars will be reused with each line)

  • MySQL LEFT JOIN, GROUP BY and ORDER BY not working as required

    - by Simon
    I have a table 'products' => ('product_id', 'name', 'description') and a table 'product_price' => ('product_price_id', 'product_id', 'price', 'date_updated') I want to perform a query something like SELECT `p`.*, `pp`.`price` FROM `products` `p` LEFT JOIN `product_price` `pp` ON `pp`.`product_id` = `p`.`product_id` GROUP BY `p`.`product_id` ORDER BY `pp`.`date_updated` DESC As you can probably guess the price changes often and I need to pull out the latest one. The trouble is I cannot work out how to order the LEFT JOINed table. I tried using some of the GROUP BY functions like MAX() but that would only pull out the column not the row. Thanks.

  • Is it possible get the functionality of namespaces inside a class?

    - by CowKingDeluxe
    I have the following code: Public Class Form1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Class What I would like to do is be able to separate the code, similar to the following (which obviously doesn't work): Public Class Form1 Namespace Step1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function End Namespace Namespace Step2 Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Namespace End Class I would like the functionality of namespaces inside of a class, as in something that would let me call Step2.Execute() instead of having to put Step2_ in front of a whole bunch of functions. I don't want to have to create separate classes / modules for step1, step2, etc. Is there a way that I can accomplish namespace functionality from inside a class?

  • Ways to optimize Android App code based on function call stack?

    - by K-RAN
    I've been told that Android OS stores all function calls in a stack. This can lead to many problems and cause the 'hiccups' during runtime, even if a program is functionalized properly, correct? So the question is, how can we prevent this from happening? The obvious solution is to functionalize less, along with other sensible acts such as refraining from excessively/needlessly creating objects, performing static calls to functions that don't access fields, etc... Is there another way though? Or can this only be done through careful code writing on the programmers' part? Does the JVM/JIT automatically optimize the bytecode during compile time to account for this?? Thanks a lot for your responses!!

  • Visual Studio 2010 element names for theming

    - by Anthony Potts
    I am trying to figure out what the element name for the tooltip is in Visual studio so that I can change the style using the extension found here. Anyone know what that is? I am using the default theme which seems to have a white to light grey gradient on it. This is less than optimal since the text for the functions are also white. In a more general question (and perhaps better), is there anything that maps the names as they are found in the theme to where they are in the IDE.

  • Drupal: How to render a form and table on same page

    - by Aaron
    Can someone help me render a form and table on the same page? I'm sure it's easy, but can't think of how to do it. Here's hook_menu: function ncbi_subsites_menu() { $items = array(); $items['admin/content/ncbi_subsites'] = array( 'title' => 'NCBI Subsites Module', 'description' => 'Informs Drupal about NCBI subsites as defined by the Content Inventory database', 'page callback' => 'ncbi_subsites_show_main_page', 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_NORMAL_ITEM, ); return $items; } Here's the callback: function ncbi_subsites_show_main_page() { $subsites = ncbi_subsites_get_subsites_from_inventory(); // fnc returns associative array from inventory, defined in include return ncbi_subsites_make_table( $subsites ); } In the callback I call some helper functions that return a themed, paged table. What I want is a small form above the table. How would I that?

  • Why is the 'this' keyword not a reference type in C++ [closed]

    - by Dave Tapley
    Possible Duplicates: Why ‘this’ is a pointer and not a reference? SAFE Pointer to a pointer (well reference to a reference) in C# The this keyword in C++ gets a pointer to the object I currently am. My question is why is the type of this a pointer type and not a reference type. Are there any conditions under which the this keyword would be NULL? My immediate thought would be in a static function, but Visual C++ at least is smart enough to spot this and report static member functions do not have 'this' pointers. Is this in the standard?

  • Read XML from an XDocument with silverlight

    - by user625310
    Hi I have managed to load an XDocument with xml data from this link http://go.yr.no/go/e/main/http://www.yr.no/place/Norway/Telemark/Sauherad/Gvarv/forecast.xml. I am using C# and .Net in Blend and producing a web app (ie some of the normal .Net functions is not included in the silverlight plugin). I have researched this a lot but can not figure out: how to put the "text" in the link node in a string variable and how to all put the "-11" from ? in a array and link it to the "time from"? I think i have to use LINQ, but the stuff on MSDN and other tutorials is confusing and to general. huge thank in advance Regards Arnt I am sorry to ask such novice questions, but i have searched a lot. Also please excuse the typos, English is not my first language. Huge thank in advance Arnt

  • Validate decimal number in (known) national format

    - by Álvaro G. Vicario
    PHP has many built-in functions to validate numbers but they all expect input in computer format: 1234.56. I need to validate stuff like 1,234.56 (English) or 1.234,56 (Spanish), together with some typical attributes (accepted range, max number of decimals, etc.). I started writing my own function but I soon got lost. It's easy to read the user input into a float variable but I want to be able to detect numbers with invalid formats like 1,23456.7 or 1..25. Do you have any recommendation on the subject? (Decimal and thousand characters are known beforehand and it's okay to hard-code digit groups as three, there's no need to cover Indian number format.)

  • Expand Expandable Listview in android on button Click

    - by user3146145
    I am implementing expandable list view with its custom adapter. The group element needs to have 2 buttons, first as a parent group element and a button below it. My problem is, I want to expand the list view on click of the button below instead of the group element. Also, The group element onClick needs to call another activity. I can disable the expanding of the expandablelistview by `mainExpListView.setOnGroupClickListener(new OnGroupClickListener() { @Override public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) { return false; }` So my questions: Is there any way to disable the group element and get it to perform other functions (Like navigate to another activity?) How to set an onclick method on them bottom image to expand? Thank you.

  • C++ setTimout function ?

    - by Quandary
    What's the cheapest way for a JavaScript like setTimeout-function in C++? I would need this: 5000 miliseconds from now, start function xy (no parameters, no return value). The reason for this is I need to initialize COM for text to speech, but when I do it on dll attach, it crashes. It works fine however if I do not call CoInitialize from dllmain. I just need to call CoInitialize and CoCreateInstance, and then use the instance in other functions. I can catch the uninitialized instance by checking for NULL, but I need to initialize COM - without crashing.

  • Delphi developer switching to C#

    - by Dorin Duminica
    Hello, I'm a Delphiholic for quite some time now and lately I was thinking of learning some C# as well, however I'm kinda' "afraid of the unknown", I've done some simple apps as a test drive for C# and I have to admit that I've liked it, HOWEVER I do not really like the IDE... that being said here's the question that I would appreciate if others who went down this path would answer: As a Delphi developer what are the "main basic" changes from the Delphi language(by basic I mean basic -- utility functions, streams, etc.), I'm used to add "System, Classes, Windows" to uses not "use System.XXX.YYY.ZZZ", I'm trying to make a partial equality in my mind from Delphi to C# until I can see where does Delphi go hand-in-hand with C# and so on... I hope the question is pretty clear, if not, do not hesitate to swear me and I'll try to clarify as well as I can :-)

  • Integer v/s int

    - by Siddhartha
    Read this on the oracle docs java.lang page: Frequently it is necessary to represent a value of primitive type as if it were an object. The wrapper classes Boolean, Character, Integer, Long, Float, and Double serve this purpose. I'm not sure I understand why these are needed. It says they have useful functions such as equals(). But if I can do (a==b), why would I ever want to declare them as Integer, use more memory and use equals()? How does the memory usage differ for the 2?

  • Can I use string concatenation to define a class CONST in PHP?

    - by selfsimilar
    I know that you can create global constants in terms of each other using string concatenation: define('FOO', 'foo'); define('BAR', FOO.'bar'); echo BAR; will print 'foobar'. However, I'm getting an error trying to do the same using class constants. class foobar { const foo = 'foo'; const foo2 = self::foo; const bar = self::foo.'bar'; } foo2 is defined without issue, but declaring const bar will error out Parse error: syntax error, unexpected '.', expecting ',' or ';' I've also tried using functions like sprintf() but it doesn't like the left paren any more than the string concatenator '.'. So is there any way to create class constants in terms of each other in anything more than a trivial set case like foo2?

  • Mix and match class in C++/MFC

    - by Coder
    I'm trying to re-factor a code base, and there is some common functionality among unrelated classes that I'd love to unite. I would like to add that functionality in common base class, but I'm not sure if it's clean and good approach. Say I have CMyWnd class and CMyDialogEx class, both different, so they cannot inherit from one base class. I want to add a button to both classes and add the message handlers to both classes as well. So I'd like to do something like this: CMyWnd : public CWnd, public COnOkBtnFunctionality, public COnCancelBtnFunctionality CMyDialogEx: public CWnd, public COnOkBtnFunctionality Where COnOkBtnFunctionality would define CButton m_buttonOk, and all the afx_msg functions it should have. And so on. Is this approach doable/good? Or are there better patterns I should resort to?

  • Equivalence Classes LISP

    - by orcik
    I need to write a program for equivalence classes and get this outputs... (equiv '((a b) (a c) (d e) (e f) (c g) (g h))) => ((a b c g h) (d e f)) (equiv '((a b) (c d) (e f) (f g) (a e))) => ((a b e f g) (c d)) Basically, A set is a list in which the order doesn't matter, but elements don't appear more than once. The function should accept a list of pairs (elements which are related according to some equivalence relation), and return a set of equivalence classes without using iteration or assignment statements (e.g. do, set!, etc.). However, set utilities such as set-intersection, set-union and a function which eliminates duplicates in a list and built-in functions union, intersection, and remove-duplicates are allowed. Thanks a lot!

  • What is the best regular expression for validating email addresses?

    - by acrosman
    Over the years I have slowly developed a regular expression that validates MOST email addresses correctly, assuming they don't use an IP address as the server part. Currently the expression is: ^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$ I use this in several PHP programs, and it works most of the time. However, from time to time I get contacted by someone that is having trouble with a site that uses it, and I end up having to make some adjustment (most recently I realized that I wasn't allowing 4-character TLDs). What's the best regular expression you have or have seen for validating emails? I've seen several solutions that use functions that use several shorter expressions, but I'd rather have one long complex expression in a simple function instead of several short expression in a more complex function.

  • jquery toggle+paginate+multiple instances

    - by mark
    Hi, I'm a jquery newbie - wanted to ask what might be the best strategy for achieving what I am after as I think it uses a mix of jquery functions : If list of items exceeds 5 items a 'more' link appears which when toggled will reveal the rest of the items. If items list is 5 or less no 'more' link is shown. Hide button also at bottom of long full revealed list. (perhaps this is toggle+pagination?) And then also that this can be used in multiple instances, as it is for multiple category menu's.(to be used in typical indexhibit websites structure like http://mikeyburton.com/) link 1 link 2 link 3 link 4 link 5 link 6 link 7 link 8 more Any help or links greatly appreciated.

  • Facebook "->api" permissions

    - by Matthieu Marcé
    I have trouble using Facebook auth on my website... I'm using the PHP Sdk and I don't understand why I can use some functions like "getLoginUrl"/"getLoginStatusUrl"/"getUser" (with right answers : the facebook session is started, i get the user's facebook ID) and when I want to use something like $me = $facebook->api("/me/permissions"); or just $me = $facebook->api("/me"); there's always an exception and nothing works ... I guess it has something to do with permissions or token maybe, but I don't know what. When the user sign up on my website, I ask permissions I need with this scope : "email,user_about_me,user_location,read_friendlists,publish_stream" A clue that the permissions seem to be ok is that when the exception occures, I ask the user to sign in again (facebook connect) and no window appears as if everything's ok, but still, the page is reloaded and the exception appears again and again... Please help, Thank you !

  • advanced search with mysql

    - by Arsenal
    I'm creating a search function for my website where the user can put in anything he likes in a textfield. It get's matched against anything (name, title, job, car brand, ... you name it) I initially wrote the query with an INNER JOIN on every table that needed to be searched. SELECT column1, column2, ... FROM person INNER JOIN person_car ON ... INNER JOIN car ... This ended up in a query with 6 or 8 INNER JOINs, and a whole lot WHERE ... LIKE '%searchvalue%' Now this query seems to cause a time'out in MySql, and I even got a warning from my hosting provider that the queries just taking up too many resources. Now obviously I'm doing this very wrong, but I was wondering how the correct approach to these kind of search functions is. Thanks!
