• PHP Extract Values From One String Based on a Pattern Defined in Another

  - by ironkeith

  I have two strings: $first = '/this/is/a/string'; $second = '/this/:param1/a/:param2'; And I'm trying to get this: $params = array('param1' => 'is', 'param2' => 'string'); But getting from point a to b is proving more than my tired brain can handle at the moment. Anything starting with a ':' in the second string defines a variable name/position. There can be any number of variables in $second which need to be extracted from $first. Segments are separated by a '/'. Thanks.

• Python - Create a list with initial capacity

  - by Claudiu

  Code like this often happens: l = [] while foo: #baz l.append(bar) #qux This is really slow if you're about to append thousands of elements to your list, as the list will have to constantly be re-initialized to grow. (I understand that lists aren't just wrappers around some array-type-thing, but something more complicated. I think this still applies, though; let me know if not). In Java, you can create an ArrayList with an initial capacity. If you have some idea how big your list will be, this will be a lot more efficient. I understand that code like this can often be re-factored into a list comprehension. If the for/while loop is very complicated, though, this is unfeasible. Is there any equivalent for us python programmers?

• What exactly does a self-describing type in .Net mean?

  - by tzup

  Given this MSDN article, we learn that the Common Type System in .Net has this classification of reference types: "Reference types can be self-describing types, pointer types, or interface types. The type of a reference type can be determined from values of self-describing types. Self-describing types are further split into arrays and class types." So an array, for instance, is a self-describing type because we can determine it's type from its values? How? Is that it, or is there more to this definition?

• Need help with writing from XML to a SQL Server database (detailed)

  - by fogedi

  I'm a bit of a newbie with XML and WebServices and stuff like that. I'm working on a project using GlassFish OpenESB to schedule a process to get some information from a webservice and then store in a database. The criteria is basically that i have to use GlassFish OpenESB or EJB modules where i can expose webservices or something along those lines, AND i have to use SQL Server 2005. So far I've been able to talk to the webservice: and receive something along those lines <?xml version="1.0" encoding="UTF-8" standalone="no"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://schemas.xmlsoap.org/soap/envelope/ http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Body> <m:entrypoint_getSettlementsOperationResponse xmlns:m="http://j2ee.netbeans.org/wsdl/BorgunTestBPEL/entrypoint_getSettlements"> <part1> <GetSettlementsByMerchantResponse xmlns="http://Borgun.Services.Gateway/2010/04/Settlement"> <GetSettlementsByMerchantResult xmlns:a="http://schemas.datacontract.org/2004/07/Borgun.Library.Common" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:msgns="http://Borgun.Services.Gateway/2010/04/Settlement" xmlns:ns0="http://j2ee.netbeans.org/wsdl/BorgunTestBPEL/entrypoint_getSettlements"> <a:CreditCardSettlement> <a:amexAmount>XXX</a:amexAmount> <a:amount>XXXX</a:amount> <a:batches> <a:CreditCardBatch> <a:batchdate>xxx</a:batchdate> <a:batchnumber>XXXX</a:batchnumber> <a:currencyCode>xxxx</a:currencyCode> <a:merchantnumber>xxxx</a:merchantnumber> <a:settlementRunNumber>xx4</a:settlementRunNumber> <a:settlementdate>2010-04-06T00:00:00</a:settlementdate> <a:slips>2</a:slips> <a:sum>xxxx</a:sum> </a:CreditCardBatch> <a:CreditCardBatch> <a:batchdate>xxx</a:batchdate> <a:batchnumber>xxxxx</a:batchnumber> <a:currencyCode>xxxx</a:currencyCode> <a:merchantnumber>xxxx</a:merchantnumber> <a:settlementRunNumber>xxxx</a:settlementRunNumber> <a:settlementdate>xxxx</a:settlementdate> <a:slips>x</a:slips> <a:sum>xxx</a:sum> </a:CreditCardBatch> </a:batches> <a:commission>xx</a:commission> <a:currencyCode>xxx</a:currencyCode> <a:deduction>-xxx</a:deduction> <a:deductionItems> <a:CrediCardSettlementDeduction> <a:amount>-xxx</a:amount> <a:code>VIÐSKF</a:code> <a:currencyCode>ISK</a:currencyCode> <a:merchantnumber>xxx</a:merchantnumber> <a:settlementrunnumber>xxx</a:settlementrunnumber> <a:text>Afsláttur v/ekorta</a:text> </a:CrediCardSettlementDeduction> <a:CrediCardSettlementDeduction> <a:amount>-335.00</a:amount> <a:code>ÁLAGKREK</a:code> <a:currencyCode>ISK</a:currencyCode> <a:merchantnumber>xxx</a:merchantnumber> <a:settlementrunnumber>xxx</a:settlementrunnumber> <a:text>xxx</a:text> </a:CrediCardSettlementDeduction> </a:deductionItems> </a:CreditCardSettlement> </GetSettlementsByMerchantResult> </GetSettlementsByMerchantResponse> </part1> </m:entrypoint_getSettlementsOperationResponse> </SOAP-ENV:Body> </SOAP-ENV:Envelope> I have access to the SQL Server 2005 server which is remote and i know i can insert into it but given that now i have a one-to-many relationship i want to be able to rollback if something fails. So in short how can I insert from this XML into the DB preferably without manually walking through the XML tree? I'm pretty sure I'm supposed to be able to use Entity and Session Beans or maybe JAXB bindings but I'm simply not being successful. One of the reasons might have something to do with the fact that the soap response contains an array of CreditCardSettlements and each of which contains an array of Batches and DeductionItems It would be best if someone can help me do this via a BPEL in GlassFish OpenESB but any hint at a java solution is much appreciated.

• Can I use MFC objects in STL containers?

  - by Jesse Stimpson

  The following code doesn't compile for me in MSVC2005: std::vector<CMenu> vec(10); CMenu is an MFC menu object (such as a context menu). Through some testing I learned that CMenu does not have a public copy constructor. To do what I wanted to do, I needed to use a dynamic array. CMenu* menus = new CMenu[10]; // ... delete [] menus; Of course, now I've lost all the benefits of using an STL container. Do I have any other options?

• Concatenating string with number in Javascript

  - by Sparky

  I'm trying to create a simple calculator in Javascript. I have an array named expression chunk[0] = 12 chunk[1] = + (the "+" sign) chunk[1] = 5 I used a for loop to loop through the chunks (chunk[]) and join then into a single expression as follows:- equation = ""; // To make var equation a string for(i = 0; i <= length; i++) { equation = equation + expression[i]; alert(expression[i]); } alert(equation); alert(expression[i]) showed values 12, + and 5. But alert(equation) showed 125 (instead of "12+5"). I need the variable equation to be "12+5" so that I can later call eval(equation) and get the value of 12+5. What am I doing wrong here?

• Unity 2D Instantiating a prefab with it's components

  - by TazmanNZL

  I have some block prefabs that I add to an array of game objects: public GameObject[]blocks; Each prefab has a BoxCollider2D, Script & Rigidbody2D components. But when I try to instantiate the prefab in the scene it doesn't appear to have the components attached? Here is how I am instantiating the prefab: for (int i = 0; i < 4; i++) { for (int j = 0; j < gridWidth; j++) { blockClone = Instantiate (blocks [Random.Range (0, blocks.Length)] as GameObject, new Vector3 (j, -i-2, 0f), transform.rotation) as GameObject; } } What am I doing wrong?

• Declaring a data type dynamically in C++

  - by Bobby

  I want to be able to do the following: I have an array of strings that contain data types: string DataTypeValues[20] = {"char", "unsigned char", "short", "int"}; Then later, I would like to create a variable of one of the data types at runtime. I won't know at compile time what the correct data type should be. So for example, if at runtime I determined a variable x needed to be of type int: DataTypeValues[3] x = 100; Obviously this won't work, so how could I do something like this?

• Can I extends a sub class of Proxy class?

  - by KCBérenger

  I want to create a complete (and real) 2-dimensional array. In order to use a maximum of Adobe code, I want to use ListCollectionView which can manage sort and filters. But to use a second dimension, I need to override getProperty method, like following code. package { import flash.utils.flash_proxy; import mx.collections.ListCollectionView; public class SubClass extends ListCollectionView /* extends Proxy */ { override flash_proxy function getProperty(name : *) : * { ... } override flash_proxy function setProperty(name : *, value : *) : void { ... } } } This code doesn't work. Flash Builder 4 said to me: 1004 Namespace was not found or is not a compile-time constant. If anyone has a solution or a clue...

• how to dynamically recolor a CGGradientRef

  I have three CGGradientRef's that I need to be able to dynamically recolor. When I Initialise the CGGradientRef's the first time I get the expected result, but every time I attempt to change the colors nothing happens. Why? gradient is an instance variable ins a subclass of CALayer: @interface GradientLayer : CALayer { CGGradientRef gradient; //other stuff } @end Code: if (gradient != NULL) { CGGradientRelease(gradient); gradient = NULL; } RGBA color[360]; //set up array CGColorSpaceRef rgb = CGColorSpaceCreateDeviceRGB(); gradient = CGGradientCreateWithColorComponents ( rgb, color, NULL, sizeof (color) / sizeof (color[0]) ); CGColorSpaceRelease(rgb); [self setNeedsDisplay];

• How to go through every record in sqllite db?

  - by Pavel

  Hi guys. I think it's kinda easy one but still I'm new to android programming so please have patience. I want to know how can I get the number of records (rows) in a specific table in my db. I need this so I can create a loop to go through every record and add each one of it to the specific Array and display it later on. This is the source: db.openDataBase(); // open connection with db Cursor c = db.getTitle(5); // loop here through db, right now I'm fetching only one record startManagingCursor(c); //adding areas to the list here Area o1 = new Area(); o1.setOrderName(c.getString(1) + c.getString(2)); m_areas.add(o1); db.close(); Does anyone can help me with this please?

• How to display the found matches of preg_match function in PHP?

  - by Eric

  I am using the following to check if links exist on file.php: $fopen = fopen('file.php', 'r'); $fread = fread($fopen, filesize('file.php')); $pattern = "/^<a href=/i"; if (preg_match($pattern, $fread)) { echo 'Match Found'; } else { echo 'Match Not Found'; } if I echo preg_match($pattern, $fread) I get a boolean value, not the found matches. I tried what was on the php.net manual and did this: preg_match($pattern, $fread, $matches); then when I echoed $matches I got "Array" message. So I tried a foreach loop and when that didn't display anything I tried $matches[0] and that too outputted nothing. So how does one go about displaying the matches found?

• PHP mysql_real_escape_string() returning `NULL`

  - by DavidYell

  I'm using PHP Version 5.1.6 and trying to escape a query string from my $_GET array. However my script is returning a NULL after it's escaped. It seems that mysql_escape_string() works fine, but it's deprecated, so I don't want to use it. Having checked over the phpinfo() the MySQL lib is all loaded fine from what I can see. Has anyone experienced this kind of thing before? $term = $_GET['q']; var_dump($term); // string(7) "richard" echo "<br />"; $sterm = mysql_real_escape_string($term, $db); var_dump($sterm); // NULL It's very strange to me, I can't imagine why this function wouldn't work.

It's not ecommerce but the best example would be an eCommerce Store-Categories-Products in terms of how the data will be accessed.

• Editing PHP using PHP (admin center)

  - by Alec Smart

  Hello, Am developing an admin center where I can edit configuration files (written in PHP). I do NOT want to store these values in a mySQL table (for various reasons). So say my config.php has contents like: <?php $option1 = 1; $option2 = 2; $option4 = 5; $option7 = array('test','a','b',c'); ?> Now say in one of the admin pages I will only be changing a few values like option2 or option4 etc. Any ideas on what would be the best way to go about this. I know one option is to read the PHP file completely and write parts of it using REGEX. Any way to make this more efficent? I don't want the config.php file to break because of some error on the user's end. Any ideas on how to ensure that it works?

• Applying transformations to NSBitmapImageRep

  - by Adam

  So ... I have an image loaded into an NSBitmapImageRep object, so I am able to examine the contents of specific pixels via a two dimensional array. Now I want to apply a couple of "transformations" to the image, in preparation for some additional processing. If I was manipulating the image manually, in Photoshop, I would: Rotate the image Crop a portion of it and discard the rest Apply a "threshold" transformation (which essentially converts the image to black and white, based on the threshold value I provide) Resample the image to shrink it down a bit (which, although losing some image quality, will speed up the subsequent processing) (not necessarily in that order) Are there objective C methods available to facilitate these specific image manipulations, with the data in the NSBitmapImageRep object? If so, can someone point me to some good examples?

• different for lusses java

  - by Ayrton

  Hi I'm having some difficulties with the following problem: I'm making a little game where you're at a specific spot and each spot has each some possible directions. The available directions are N(ord),E(ast),S,W . I use the function getPosDirections to get the possible directions of that spot. The function returns the directions into an ArrayList e.g. for spot J3: [E,W] Now the game goes like this: 2 dices will be rolled so you get a number between 2 and 12, this number represents the number of steps you can make. What I want is an ArrayList of all the possible routes e.g.: I throw 3 and I'm currently at spot J3: [[E,N,E],[E,N,S],[E,S,E],[E,S,S],[W,N,E],[W,N,S],[W,S,E],[W,S,S]] How would obtain the last mentioned Array(list) Thanks in advance
