• Sending images using Http Post

  - by primal

  I want to send an image from the android client to the Django server using Http Post. The image is chosen from the gallery. At present, I am using list value name Pairs to send the necessary data to the server and receiving responses from Django in JSON. Can the same approach be used for images (with urls for images embedded in JSON responses)? Also which of, accesssing images remotely without downloading them from the server or downloading and storing them in a Bitmap array and using them locally is a better method? The images are few in number (<10) and small in size (50*50 dip). Any tutorial to tackle these problems would be much appreciated.

• 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...

Thanks.

• 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?

• 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?

• 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.

• 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.

  So, I am able to create an array that populates the fields of the Table, but am having troubles creating the subtext that appears below the main fields. I currently have: - (void)viewDidLoad { [super viewDidLoad]; listOfForms = [[NSMutableArray alloc] init]; [listOfForms addObject:@"First Form"]; } and then: NSString *cellValue = [listOfDAForms objectAtIndex:indexPath.row]; cell.textLabel.text = cellValue; in the cellForRowAtIndexPath portion. Why can't I add: listOfNames = [[NSMutableArray alloc] init]; [listOfNames addObject:@"Named Form"]; and NSString *cellSubscript = [listOfNames objectAtIndex:indexPath.row]; cell.detailTextLabel.text = cellSubscript; in order to make the little subview work? 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?

• need a code snippet to find all *.html under a folder in nodejs

  - by Nicolas S.Xu

  I'd like to find all *.html files in src folder and all its sub folders using nodejs. What is the best way to do it? var folder = '/project1/src'; var extension = 'html'; var cb = function(err, results) { // results is an array of the files with path relative to the folder console.log(results); } // This function is what I am looking for. It has to recursively traverse all sub folders. findFiles(folder, extension, cb); I think a lot developers should have great and tested solution and it is better to use it than writing one myself.

• 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?

• How to peform an external request in Kohana 3?

  - by alex

  I've always used cURL for this sort of stuff, but this article got me thinking I could request another page easily using the Request object in Kohana 3. $url = 'http://www.example.com'; $update = Request::factory($url); $update->method = 'POST'; $update->post = array( 'key' => 'value' ); $update->execute(); echo $update->response; However I get the error Accessing static property Request::$method as non static From this I can assume it means that the method method is static, but that doesn't help me much. I also copied and pasted the example from that article and it threw the same error. Basically, I'm trying to POST to a new page on an external server, and do it the Kohana way. So, am I doing this correctly, or should I just use cURL (or file_get_contents() with context)?

• How do I extract info from a block of URLs in php?

  - by Jack

  I have a list of urls, which can come in any format. One per line, separated by commas, have random text in between them, etc. the URLs are all from 2 different sites, and have a similar structure For this example, lets say it looks like this Random Text - http://www.domain2.com/variable-value Random Text 2 - http://www.domain1.com/variable-value, http://www.domain1.com/variable-value, http://www.domain1.com/variable-value http://www.domain1.com/variable-value http://www.domain2.com/variable-value http://www.domain1.com/variable-value http://www.domain2.com/variable-value http://www.domain1.com/variable-value I need to extract 2 pieces of information. Check to see if its domain1 or domain2 and the value that follows "variable-" So it should create a multi-dimensional array, which would have 2 items: domain + value. Whats the best way of doing that?
