  • SilverLight WebApp Calling Webservice in the same solution

    - by Ben
    Hi, I have a website solution that is composed of a SilverLight Project and an ASP Site that contains an asmx Webservice. The SilverLight project calls various methods in the Webservice, and this works fine on my home PC. When i publish the site (using 123-Reg if that makes a difference), it appears that the SilverLight app is no longer able to call the webservice. I have tried debugging the app by pointing my local version of the site to my published webservice and i get a "policy" issue. I know that 123 Reg have .Net 3.5 running on their servers, so i would assume that the site should "just work" when i publish it. Am i making a hugely stupid assumption there? Is there anything that i can do to change the "policies" within my app? Or is there another way around what i am trying to do ( i need to keep the webservice, as i want for it to be used from other places, and dont really want to duplicate code and create the same methods within the SilverLight project). Thanks

  • License similar to the MIT license but without the ability to sell?

    - by Ben
    I'm trying to decide how I want to license my Wordpress themes to the public. I know that the GPL is recommended to Wordpress theme creators, however I feel it might not be liberal enough for me because I want businesses to be able to use them if they want to. I really like the MIT license, the only thing that gets me is the freedom to sell part. I don't want someone taking my themes and selling them on some theme farm site, they should be free for everyone, however I don't want to require them to republish any changes under the MIT as well, I think that that freedom should remain intact. Is there a license that sort of fits into the terms I specified here? I'm not a lawyer so I have trouble reading through the complicated language of licenses. If there is not a similar license to the MIT but with the terms I have specified, should I just license under a modified MIT? If so, can anyone help me write it? Thanks very much!

  • Queuing methods to be run on an object by different threads in Python

    - by Ben
    Let's say I have an object who's class definition looks like: class Command: foo = 5 def run(self, bar): time.sleep(1) self.foo = bar return self.foo If this class is instantiated once, but different threads are hitting its run method (via an HTTP request, handled separately) passing in different args, what is the best method to queue them? Can this be done in the class definition itself?

  • Emulate disk IO speeds in Android SDK

    - by Ben L.
    I don't have a physical Android device to work with, so all I can use is the emulator. I'm wondering if there's something I could use to make the IO speeds more realistic - How do I slow down disk access to the speed it would be on a physical device? Also, this may be unrelated, but when I change the speed and latency options in Eclipse ADT DDMS view, I don't notice any change in internet speed on the emulator. Is this a bug?

  • How do I work with constructs in PHPUnit?

    - by Ben Dauphinee
    I am new into PHPUnit, and just digging through the manual. I cannot find a decent example of how to build a complete test from end to end though, and so, am left with questions. One of these is how can I prep my environment to properly test my code? I am trying to figure out how to properly pass various configuration values needed for both the test setup/teardown methods, and the configs for the class itself. // How can I set these variables on testing start? protected $_db = null; protected $_config = null; // So that this function runs properly? public function setUp(){ $this->_acl = new acl( $this->_db, // The database connection for the class passed // from whatever test construct $this->_config // Config values passed in from construct ); } // Can I just drop in a construct like this, and have it work properly? // And if so, how can I set the construct call properly? public function __construct( Zend_Db_Adapter_Abstract $db, $config = array(), $baselinedatabase = NULL, $databaseteardown = NULL ){ $this->_db = $db; $this->_config = $config; $this->_baselinedatabase = $baselinedatabase; $this->_databaseteardown = $databaseteardown; } // Or is the wrong idea to be pursuing?

  • (Not So) Silly Objective-C inheritance problem when using property - GCC Bug?

    - by Ben Packard
    Update 2 - Many people are insisting I need to declare an iVar for the property. Some are saying not so, as I am using Modern Runtime (64 bit). I can confirm that I have been successfully using @property without iVars for months now. Therefore, I think the 'correct' answer is an explanation as to why on 64bit I suddenly have to explicitly declare the iVar when (and only when) i'm going to access it from a child class. The only one I've seen so far is a possible GCC bug (thanks Yuji). Not so simple after all... Update - I messed up one line of the original copy and paste - corrected. The @property call was missing (nonatomic, retain) but is a red herring - STILL NEED AN ANSWER! Thanks. I've been scratching my head with this for a couple of hours - I haven't used inheritance much. Here I have set up a simple Test B class that inherits from Test A, where an ivar is declared. But I get the compilation error that the variable is undeclared. This only happens when I add the property and synthesize declarations - works fine without them. TestA Header: #import <Cocoa/Cocoa.h> @interface TestA : NSObject { NSString *testString; } @end TestA Implementation is empty: #import "TestA.h" @implementation TestA @end TestB Header: #import <Cocoa/Cocoa.h> #import "TestA.h" @interface TestB : TestA { } @property (nonatomic, retain) NSString *testProp; @end TestB Implementation (Error - 'testString' is undeclared) #import "TestB.h" @implementation TestB @synthesize testProp; - (void)testing{ NSLog(@"test ivar is %@", testString); } @end

  • Scala and the Java Memory Model

    - by Ben Lings
    The Java Memory Model (since 1.5) treats final fields differently to non-final fields. In particular, provided the this reference doesn't escape during construction, writes to final fields in the constructor are guaranteed to be visible on other threads even if the object is made available to the other thread via a data race. (Writes to non-final fields aren't guaranteed to be visible, so if you improperly publish them, another thread could see them in a partially constructed state.) Is there any documentation on how/if the Scala compiler creates final (rather than non-final) backing fields for classes? I've looked through the language specification and searched the web but can't find any definitive answers. (In comparison the @scala.volatile annotation is documented to mark a field as volatile)

  • Meaning of Execute_priv on mysql.db table

    - by Ben Reisner
    I created user 'restriceduser' on my mysql server that is 'locked down'. The mysql.user table has a N for all priveledges for that account. The mysql.db table has Y for only Select, Insert, Update, Delete, Create, Drop; all other privileges are N for that account. I tried to create a stored procedure and then grant him access to run only that procedure, no others, but it does not work. The user receives: Error: execute command denied to user 'restricteduser'@'%' for routine 'mydb.functionname' The stored procedure: CREATE DEFINER = 'restriceduser'@'%' FUNCTION `functionname`(sIn MEDIUMTEXT, sformat MEDIUMTEXT) RETURNS int(11) NOT DETERMINISTIC CONTAINS SQL SQL SECURITY DEFINER COMMENT '' BEGIN .... END; The grant statement I tried: GRANT EXECUTE ON PROCEDURE mydb.functionname TO 'restricteduser'@'%'; I was able to work around by modifying his mysql.db entry with update mysql.db set execute_priv='Y' where user='restricteduser' This seems to be more then I want, because it opens up permissions for him to run any stored procedure in that database, while I only wanted him to have permissions to run the designated function. Does anyone see where my issue may lie?

  • Amazon Product API: "Your request is missing a required parameter combination" on Blended ItemSearch

    - by Daniel Schaffer
    I'm having some problems trying to do an ItemSearch on the Blended index using the Amazon Product API. According to the documentation, Blended requests cannot specify the MerchantId parameter - and indeed, if I try to include it I get an error telling me so. However, when I don't include it, I get an error telling me that my request is missing a required parameter combination and that a valid combination includes MerchantId... what the hell? Here's the XML response: <Items xmlns="http://webservices.amazon.com/AWSECommerceService/2005-10-05"> <Request> <IsValid>False</IsValid> <ItemSearchRequest> <Availability>Available</Availability> <Condition>All</Condition> <Keywords> home theater pc and other geekery</Keywords> <ResponseGroup>Similarities</ResponseGroup> <ResponseGroup>SalesRank</ResponseGroup> <ResponseGroup>OfferSummary</ResponseGroup> <ResponseGroup>Small</ResponseGroup> <ResponseGroup>Images</ResponseGroup> <SearchIndex>Blended</SearchIndex> </ItemSearchRequest> <Errors> <Error> <Code>AWS.MissingParameterCombination</Code> <Message>Your request is missing a required parameter combination. Required parameter combinations include MerchantId, Availability.</Message> </Error> </Errors> </Request> </Items> The failing requests are being sent as part of batches with other requests that are succeeding. I'm using REST to send my requests, so here's an example of a request: http://ecs.amazonaws.com/onca/xml?AWSAccessKeyId=-------------& ItemSearch.1.Keywords=Mates%20of%20State& ItemSearch.1.MerchantId=Amazon& ItemSearch.1.SearchIndex=DVD& ItemSearch.2.Keywords=teaching%20Lily%20various%20computer%20related%20skills& ItemSearch.2.SearchIndex=Blended& ItemSearch.Shared.Availability=Available& ItemSearch.Shared.Condition=All& ItemSearch.Shared.ResponseGroup=Small%2CSalesRank%2CImages%2COfferSummary%2CSimilarities& Operation=ItemSearch%2CSimilarityLookup& Service=AWSECommerceService& SimilarityLookup.1.ItemId=B000FNNHZ2& SimilarityLookup.2.ItemId=B000EQ5UPU& SimilarityLookup.Shared.Availability=Available& SimilarityLookup.Shared.Condition=All& SimilarityLookup.Shared.MerchantId=Amazon& SimilarityLookup.Shared.ResponseGroup=Small%2CSalesRank%2CImages%2COfferSummary& Timestamp=2010-04-02T17%3A18%3A05Z& Signature=---------------- Any ideas as to what I'm doing wrong?

  • Counting viable sublist lengths from an array.

    - by Ben B.
    This is for a genetic algorithm fitness function, so it is important I can do this as efficiently as possible, as it will be repeated over and over. Lets say there is a function foo(int[] array) that returns true if the array is a "good" array and false if the array is a "bad" array. What makes it good or bad does not matter here. Given the full array [1,6,8,9,5,11,45,16,9], lets say that subarray [1,6,8] is a "good" array and [9,5,11,45] is a "good" array. Furthermore [5,11,45,16,9] is a "good" array, and also the longest "good" subarray. Notice that while [9,5,11,45] is a "good" array, and [5,11,45,16,9] is a "good" array, [9,5,11,45,16,9] is a "bad" array. We wants the length counts of all "good" arrays, but not subarrays of "good" arrays. Furthermore, as described above, a "good" array might begin in the middle of another "good" array, but the combination of the two might be a "bad" array.

  • What is the best way, if possible, to send information from a Java PrintStream to a JTextPane?

    - by Daniel Reeves
    In Java, I have a package that translates XML metadata from one standard to another. This package is ultimately accessed through a single function and sends all of its output through a PrintStream object. The output sent is just a status of each file and whether or not it was translated. This is pretty fine and dandy if I'm just printing to System.out, but I'm actually wanting to print this to a JTextPane while it translates (kind of like a progress text box). It wouldn't be a big deal to just print the status after it was done translating the XML, but since there may be thousands of XML files, that's just not feasible. One thing that I've tried is to use a thread that takes all of the information from the PrintStream (which is attached to a ByteArrayOutputStream) and let it send any new information to the text pane. Unfortunately, this still sends the information all at once at the end of the translation. This does work correctly for System.out. Here's the code that does the translation and tries to show the output: public class ConverterGUI extends javax.swing.JFrame { boolean printToResultsBox = false; PrintStream printStream = null; ByteArrayOutputStream baos = null; private class ResultsPrinter implements Runnable { public ResultsPrinter() { baos = new ByteArrayOutputStream(); printStream = new PrintStream(baos); } public void run() { String tempString = ""; while (printToResultsBox) { try { if (!baos.toString().equals(tempString)) { tempString = baos.toString(); resultsBox.setText(tempString); } } catch (Exception ex) { } } } } ... ResultsPrinter rp = new ResultsPrinter(); Thread thread = new Thread(rp); thread.start(); // Do the translation. try { printToResultsBox = true; boolean success = false; TranslationEngine te = new TranslationEngine(); // fileOrFolderToConvert is a text box in the GUI. // linkNeeded and destinationFile are just parameters for the translation process. success = te.translate(fileOrFolderToConvert.getText(), linkNeeded, destinationFile, printStream); if (success) { printStream.println("File/folder translation was a success."); } resultsBox.setText(baos.toString()); } catch (Exception ex) { printStream.println("File translation failed."); } finally { printToResultsBox = false; } ... } Ultimately, this code prints out to the JTextPane just fine after all the translation is done but not during. Any suggestions? Do I need to change the PrintStream to something else?

  • Perl: Unsuccessful stat on filename containing newline. What?

    - by Daniel
    Hello, I am getting an error I do not understand. I am using File:find to recurse a fylesystem on windows using Activestate Perl 5.8.8 and trying to stat $File::Find::name; so I am not stat-ing a filename got from a text file scanning requiring chomp-ing or newline removing. I was unable to get file modification time, the m in: my ($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,$blocks) = stat($File::Find::name); so trying a -s $File::Find::name give me the error: "Unsuccessful stat on filename containing newline" A typical file name found is F01-01-10 Num 0-00000.pdf but I get the same error even renaming in E02.pdf Some ideas about a possible reason for this error?

  • How to know which process hold a semnum with a specific number?

  • The Immerman-Szelepcsenyi Theorem

    - by Daniel Lorch
    In the Immerman-Szelepcsenyi Theorem, two algorithms are specified that use non-determinisim. There is a rather lengthy algorithm using "inductive counting", which determines the number of reachable configurations for a given non-deterministic turing machine. The algorithm looks like this: Let m_{i+1}=0 For all configurations C Let b=0, r=0 For all configurations D Guess a path from I to D in at most i steps If found Let r=r+1 If D=C or D goes to C in 1 step Let b=1 If r<m_i halt and reject Let m_{i+1}=m_{i+1}+b I is the starting configuration. m_i is the number of configurations reachable from the starting configuration in i steps. This algorithm only calculates the "next step", i.e. m_i+1 from m_i. This seems pretty reasonable, but since we have nondeterminisim, why don't we just write: Let m_i = 0 For all configurations C Guess a path from I to C in at most i steps If found m_i = m_i + 1 What is wrong with this algorithm? I am using nondeterminism to guess a path from I to C, and I verify reachability I am iterating through the list of ALL configurations, so I am sure to not miss any configuration I respect space bounds I can generate a certificate (the list of reachable configs) I believe I have a misunderstanding of the "power" of non-determinisim, but I can't figure out where to look next. I am stuck on this for quite a while and I would really appreciate any help.

  • Setting Mnemonics and Hot Keys for a JOptionPane Dialog

    - by Daniel Bingham
    Is it possible to assign hotkeys and mnemonics to the buttons in a JOptionPane Dialog? I'd like to be able, in a JOptionPane generated message dialog with the options Yes, No and Cancel, press Y to hit the Yes button, N to hit the No button and escape to activate the escape button. Similarly in a dialog with Okay and Cancel buttons I'd like to be able to activate them with enter and escape. I've attempted passing JButtons into the JOptionPane's button Object array with the Mnemonics set already. The mnemonics work and the buttons show up correctly in the dialogs, however, they do not act properly when they are activated. Most noticeably they do not dispose of the dialog. What is the correct way to add hotkeys and Mnemonics to a JOptionPane Dialog's buttons? As always, my apologies ahead of time if this is a duplicate - I searched both Google and Stackoverflow and found nothing.

  • Watir not working in Windows 7

    - by Ben Mills
    I recently did a fresh install of Windows 7. I installed Ruby 1.8.6 and Watir via RubyGems. When I try to run a Watir script, IE opens and the first page is called, but the problem seems to be that the script doesn't wait for the page to finish loading (which it's always done in the past). Subsequent lines in the script try to access page elements that haven't loaded yet. Is anyone else having this problem?

  • Scaling an Image in GWT

    - by Daniel
    Changing the size of an Image Widget in GWT changes the size of the image element, but does not rescale the image on the screen. Therefore, the following will not work: Image image = new Image(myImageResource); image.setHeight(newHeight); image.setWidth(newWidth); image.setPixelSize(newWidth, newHeight); This is because GWT implements its Image widget by setting the background-image of the HTML <img... /> element as the image, using CSS. How does one get the actual image to resize?
