• Visual Studio / Blend... how you organize that?

  - by TomTom

  Virst time more complex stuff in WPF. I am a little lost on the split betwen VS and Blend. It seems I am VERY limited with editors in Visual Studio for editing controls - when customizing, for example, it seems I Can enter astyle in XML... but in blend I Can tell it to make a copy of the CURRENT style and use that as a starter, definitely more convenient. I understand the "difference in focus", but it seems to me that i Really need both tools to work, especially if the controls I Do are: More complex Not user controls "on purpose" (to allow more customization by programmes using the application). THis means when I do a control, my approach would be: Work on the backend as good as it gets without front end (i.e. implement all methods needed etc., but can be dummies) Switch over to Blend (closing visual studio - as the projcet must be closed) Put in the initial templating Switch over to VIsual Studio (closing blend) Put logic in and debug. This seems pretty counterintuitively. Am I missing something obvious here?

• Is is possible to determine a password input string as plaintext or hashed?

  - by Godders

  I have a RESTful API containing a URI of /UserService/Register. /UserService/Register takes an XML request such as: <UserRegistrationRequest> <Password>password</Password> <Profile> <User> <UserName>username</UserName> </User> </Profile> </UserRegistrationRequest> I have the following questions given the above scenario: Is there a way (using C# and .Net 3.5+) of enforcing/validating that clients calling Register are passing a hashed password rather than plaintext? Is leaving the choice of hashing algorithm to be used to the client a good idea? We could provide a second URI of /UserService/ComputePasswordHash which the client would call before calling /UserService/Register. This has the benefit of ensuring that each password is hashed using the same algorithm. Is there a mechanism within REST to ensure that a client has called one URI before calling another? Hope I've explained myself ok. Many thanks in advance for any help.

• Duplicate Symbol Linker Error (C++ help)

  - by Vash265

  Hi. I'm learning some CSP (constraint satisfaction) theory stuff right now, and am using this library to parse XML files. I'm using Xcode as an IDE. My program compiles fine, but when it goes to link the files, I get a duplicate symbol error with the XMLParser_libxml2.hh file. My files are separated as such: A class header file that includes the XMLParser file above A class implementation file that include the class header file A main file that includes the class header file The duplicate symbol is occurring in main.o and classfile.o, but as far as I can tell, I'm not actually adding that .hh file twice. Full error: ld: duplicate symbol bool CSPXMLParser::UTF8String::to<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >(std::basic_string<char, std::char_traits<char>, std::allocator<char> >&) constin /Users/vash265/CSP/Untitled/build/Untitled.build/Debug/Untitled.build/Objects-normal/x86_64/dStructFill.o and /Users/vash265/CSP/Untitled/build/Untitled.build/Debug/Untitled.build/Objects-normal/x86_64/main.o Copying the implementation of the class into the main file and taking the class implementation file out of the compilation target alleviates the error, but it's a disorganized mess this way, and I'll be adding more classes very soon (and it would be nice to have them in separate files). As I've come to understand it, this is caused by the file (XMLParser_libxml2.hh) having both the class and function definition and implementation in one file (and it seems as though this might have been necessary due to the use of templates in that 'header' file). Any ideas on how to get around sticking all my class files in my main.cpp? (I've tried ifdefs, they don't work).

• jquery script that used to work is not working with jquery 1.4.2

  ... and i cant figure out why.

• WebView and HTML5 <video>

  - by brian moore

  I'm piecing together a cheapo app that amongst other things "frames" some of our websites... Pretty simple with the WebViewClient... until I hit the video. The video is done as HTML5 elements, and these work fine and dandy on Chrome, iPhones, and now that we fixed the encoding issues it works great on Android... in the native browser. Now the rub: WebView doesn't like it. At all. I can click on the poster image, and nothing happens. Googling, I found http://www.codelark.com/2010/05/12/android-viewing-video-from-embedded-webview/ which is close, but seems to be based on a 'link' (as in a href...) instead of a video element. (onDownloadListener does not appear to get invoked on video elements...) I also see references to overriding onShowCustomView, but that seems to not get called on video elements... nor does shouldOverrideUrlLoading.. I would rather not get into "pull xml from the server, reformat it in the app".. by keeping the story layout on the server, I can control the content a bit better without forcing people to keep updating an app. So if I can convince WebView to handle tags like the native browser, that would be best. I'm clearly missing something obvious.. but I have no clue what.

• Jetty 7 will not allow me to customize a session cookie path

  - by Bob Obringer

  Using Jetty 7.0.2, I am unable to set a custom session cookie path. I am hosting multiple sites on the same server using apache to proxy requests to the proper context. (replaced http as htp as stackoverflow thinks my multiple links might be spam) <VirtualHost *:80> ServerName context.domain.com ProxyRequests On ProxyPreserveHost Off <Proxy *:80> Order deny,allow Allow from 127.0.0.1 </Proxy> ProxyPass / htp://localhost:8080/context/ ProxyPassReverse / htp://localhost:8080/context/ <Location /> Order allow,deny Allow from all </Location> </VirtualHost> Jetty is running on the same server on port 8080 and my context is available @ /context The user accesses the application @ htp://context.domain.com but jetty is setting the path for the session cookie @ /context. This prevents the browser from accessing the cookie since the the actual path to the context is not being used. I need to override Jetty's default setting to set the cookie for the context, and set the path at the root ( / ). In my Jetty's webdefault.xml I have the following, which is partially working: <context-param> <param-name>org.eclipse.jetty.servlet.SessionCookie</param-name> <param-value>CustomCookieName</param-value> </context-param> <context-param> <param-name>org.eclipse.jetty.servlet.SessionPath</param-name> <param-value>/</param-value> </context-param> The cookie is properly set with a custom name, but it is NOT setting the SessionPath. No matter what I set the value to... it refuses to set a cookie at any path but /context. This has been driving me crazy so any help would be greatly appreciated.

• custom rss feed suddenly does not work anymore

  - by krike

  I just don't understand what's happening, I haven't change anything to the site for a few months but now suddenly the rss feed doesn't work anymore. I create a php file with the following code: header('Content-type: text/xml'); include("config/config.inc.php"); $result = mysqli_query($link, "SELECT * FROM tutorials ORDER BY tutorial_id DESC LIMIT 50"); ?> <rss version="2.0"> <channel> <title>CMS tutorial site</title> <description>Bringing you the best CMS tutorials from the web</description> <link>http://cmstutorials.org</link> <?php while($row = mysqli_fetch_object($result)) { $user = mysqli_fetch_object(mysqli_query($link, "SELECT * FROM user_extra WHERE userid=".$row->user_id."")); ?> <item> <title><?php echo $row->title; ?></title> <author><?php echo $user->username; ?></author> <description><?php echo $row->description; ?></description> <pubDate><?php echo $row->date; ?></pubDate> <link>http://cmstutorials.org/view_tutorial.php?tutorial_id=<?php echo $row->tutorial_id; ?></link> </item> <?php } ?> </channel> </rss> I checked the query by executing it in phpmyadmin and it works, doesn't give any error. When I delete the header content type and the rss tag it will print out each line from the query but the feed won't display anything this is the link of the feed http://cmstutorials.org/rss (or http://cmstutorials.org/rss.php)

• Hibernate collection multiple types

  - by CaptainAwesomePants

  I have a class Player that contains a list of Accessory objects. There are two kinds of Accessories. SocketedAccessories have a list of SocketJewels, and MagicAccessories have a list of MagicEnchantments. At the database level, there is a players table that represents the player, and an accessories table that contains a list of accessories. Accessories have a type field that indicates whether they are socketed or magical, and the columns that are only used by one type are just left blank by entries of the other type. There are socket_jewels and magic_enchantments tables, representing the socket jewels or the magic enchantments on each accessory. I am trying to figure out the correct way to map this with Hibernate. One way would be for the player to have two lists of accessories, one for SocketedAccessories and one for MagicAccessories. That seems undesirable, though. What I want is a way to specify that player should have a field List<Accessory> accessories that contains both types of thing. Is there a way to tell Hibernate, in either hbm.xml or annotations, to do this?

• NSNotification vs. Delegate Protocols?

  - by jr

  I have an iPhone application which basically is getting information from an API (in XML, but maybe JSON eventually). The result objects are typically displayed in view controllers (tables mainly). Here is the architecture right now. I have NSOperation classes which fetch the different objects from the remote server. Each of these NSOperation classes, will take a custom delegate method which will fire back the resulting objects as they are parsed, and then finally a method when no more results are available. So, the protocol for the delegates will be something like: (void) ObjectTypeResult:(ObjectType *)result; (void) ObjectTypeNoMoreResults; I think the solution works well, but I do end up with a bunch of delegate protocols around and then my view controllers have to implement all these delegate methods. I don't think its that bad, but I'm always on the lookout for a better design. So, I'm thinking about using NSNotifications to remove the use of the delegates. I could include the object in the userInfo part of the notification and just post objects as received, and then a final event when no more are available. Then I could just have one method in each view controller to receive all the data, even when using multiple objects in one controller.† So, can someone share with me some pros/cons of each approach. Should I consider refactoring my code to use Events rather then the delegates? Is one better then the other in certain situations? In my scenario I'm really not looking to receive notifications in multiple places, so maybe the protocol based delegates are the way to go. Thanks!

• Ajax request (from .NET) give me unexpected results

  - by ironnailpiercethesky

  I wanted to learn a little more about web and .NET so i decided to write a program to download binaries, webpages and does a little ajax. The first download site i tried was too easy. So i went against uploading.com. It seemed good, no captcha, some ajax use required, you cant guess all the data, it was perfect. After 2hours of messing around i got frustrated. For the life of me i could not get the ajax response to give me what i was expecting. I decided to use tamper data clear my cookies, click on the entry for the ajax request. Copy the Referer, cookies and postdata and came up with this code. It does not work! I am shocked that copying those fields did not work. I even tried setting the user agent (not in code linked) and it still did not work. Why isnt this POST on the ajax request not giving me the correct file? I notice the JsHttpRequest=12719132559480-xml changes based on time so if you want to run the code you should grab a new snapshot with tamperdata (or at least update that url). I dont see any extra headers in tamper data so does anyone know why i might not be getting the response expected? I know disabling cookies or javascript will make the link 'expired' automatically. I dont think javascript will matter because i got the data from tamperdata at the moment of request so what gives? What am i forgetting or what data am i not submitting properly?

• What is the performance impact of CSS's universal selector?

  - by Bungle

  I'm trying to find some simple client-side performance tweaks in a page that receives millions of monthly pageviews. One concern that I have is the use of the CSS universal selector (*). As an example, consider a very simple HTML document like the following: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Example</title> <style type="text/css"> * { margin: 0; padding: 0; } </head> <body> <h1>This is a heading</h1> <p>This is a paragraph of text.</p> </body> </html> The universal selector will apply the above declaration to the body, h1 and p elements, since those are the only ones in the document. In general, would I see better performance from a rule such as: body, h1, p { margin: 0; padding: 0; } Or would this have exactly the same net effect? Essentially, what I'm asking is if these rules are effectively equivalent in this case, or if the universal selector has to perform more unnecessary work that I may not be aware of. I realize that the performance impact in this example may be very small, but I'm hoping to learn something that may lead to more significant performance improvements in real-world situations. Thanks for any help!

• Form Encoding Problems on GRAILS 2.0

  - by ArmlessJohn

  I have an Grails application that is configured everywhere to function as UTF-8. While running a debug version, headers say Content-Type:text/html;charset=utf-8, and meta tags agree. Browser identified page as UTF-8 and shows characters correctly. When posting a form, the browser correctly sends it encoded as UTF-8. When reading the data via params.paramname, however, the data looks garbled; maçã becomes maçã. Upon further inspection, it seems the form is sending UTF-8 data, but Grails seem to try and read it as if it was ISO-8859-1. Setting accept-charset="ISO-8859-1" on the form confirms this problem, as it fixes the problem. I also have this on applicationContext.xml: <bean id="characterEncodingFilter" class="org.springframework.web.filter.CharacterEncodingFilter"> <property name="encoding"> <value>utf-8</value> </property> <property name="forceEncoding"> <value>true</value> </property> </bean> Is there an solution for this besides adding accept-charset="ISO-8859-1" to all forms in the application? Thanks.

• How to accept an incoming call by clicking a button?

  - by upright

  HI, all! I'm trying to implement my own phone call handling UI. What I want to do is, if a call comes in, the incoming telephone number and a picture are displayed, and, if I press a button, the incoming call will be accepted/answered. The related codes are: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); answerButton = (Button) findViewById(R.id.pickup); answerButton.setOnClickListener(new OnClickListener() { public void onClick(final View v) { Intent intent = new Intent("android.intent.action.ANSWER"); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); } }); Sadly, the code does not work. At first, an exception is thrown if I press my answer button: ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.ANSWER Then I added an entry in the AndroidManifest.xml: I run the app again, there is no exception anymore. However, I doubt the incoming call is not really accepted. Because if the press the Android's screen answer button (green button), the incoming call is accepted and a green button is also displayed on the upper left corner of the emulator screen, while my app doesn't. I also read the Phone app's source code in android source. There is method such as acceptCall() in the Phone class. But these codes seem difficult for me to use, because there are many imports declaration in the code, such as : import com.android.internal.telephony.Call; import com.android.internal.telephony.CallStateException; import com.android.internal.telephony.CallerInfo; import com.android.internal.telephony.CallerInfoAsyncQuery; import com.android.internal.telephony.Connection; import com.android.internal.telephony.MmiCode; import com.android.internal.telephony.Phone; And, if I add these imports in my code, there will be too many errors, such as : "The import com.android.internal.telephony cannot be resolved" What is the right and simple way for my problem? Thanks in advance!

• Using the Loader display object to load X jpegs, then resize each of the images differently while th

  - by Supernovah

  Hey there, I was wondering if this is possible to do I am able to load the image in and have it displayed easily enough by using addChild(myLoader); where myLoader is in the classWide private scope. The problem is, whenever I call my function inside that class which adds the loader to the stage, it clears the old one and puts this new one in even if I add a bit where I change myLoader.name to something related to how many images it has completed. This is a serious hinderance as I can't do anything besides KNOW how many images I will need to load and write the code X times. The problem being is that the urls are read from an XML file. My main desire was to have a classWide private Array which contained my loaders and I would assign them using myArray.push(myLoader) each time the load had completed. There is a problem which is that it compiles but they never get displayed it would work as this is written public class Images extends Sprite { private var imagesLoaded = 0; private var myLoader:Loader; ... public function Images():Void { myLoader = new Loader; //loop calling a myLoader.load(imageURL) for a bunch of urls myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded); } public function imageLoaded { myArray[imagesLoaded] = myLoader; trace("does\'nt get to here!!"); addChild(myArray[imagesLoaded]); imagesLoaded++; } }

  in continuation to the question from last week: http://stackoverflow.com/questions/2828237/problem-configure-jboss-to-work-with-jndi I'm trying to bind datasource in JBoss and use it in my application. In my struggling, I already managed to avoid the javax.naming.NameNotFoundException by: 1. using in java new InitialContext().lookup(connection); instead of new JndiObjectFactoryBean().setJndiName(connection); 2. changing the connection name from: 'jndi-name' to 'java:jndi-name' Now the problem is that the datasouce that I get from the lookup is null. I created the datsource file: <datasources> <local-tx-datasource> <jndi-name>bilby</jndi-name> <connection-url>jdbc:oracle:myURL</connection-url> <driver-class>oracle.jdbc.OracleDriver </driver-class> <user-name>myUsername</user-name> <password>myPassword</password> <exception-sorter-class- name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name> <metadata> <type-mapping>Oracle9i</type-mapping> </metadata> </local-tx-datasource> </datasources> and put it under \server\default\deploy\oracle-ds.xml I get during runtime the line: 18:37:56,560 INFO [ConnectionFactoryBindingService] Bound ConnectionManager 'jb oss.jca:service=DataSourceBinding,name=bilby' to JNDI name 'java:bilby' So my question is - why do I get null as my datasource???

• How to inherit the current path when invoking Maven's exec-maven-plugin?

  - by wishihadabettername

  I have an <exec-maven-plugin> which calls an external command (in this case, svnversion). The command is in the path for the current user. However, when a separate shell is spawned by the plugin, the path is not initialized. I don't want to hardcode or define a variable for each external command (there would be too much to maintain, especially that there are both Windows and *nix users). My pom.xml contains the following: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.1</version> <executions> <execution> <id>svnversion-exec</id> <phase>process-resources</phase> <goals> <goal>exec</goal> </goals> <configuration> <executable>svnversion</executable> <arguments> <argument><![CDATA[ >version.txt ]]></argument> </arguments> </configuration> </execution> </executions> </plugin> Currently I get the following output: [INFO] [exec:exec {execution: svnversion-exec}] 'svnversion' is not recognized as an internal or external command, operable program or batch file. [ERROR] BUILD ERROR: Result of cmd.exe /X /C "svnversion >version.txt" execution is: '1'. Thank you!

• Projects integration question

  - by qkrsppopcmpt

  Other team has one legacy system, which is data aggregators. It is implemented as web service using JAVA, SOAP,MTOM,Tomcat and Axis2. They have wsdl files defining functionalities such as search, retrieve data, upload, download. Our team has a new developed website which is developed using RoR with mySQL. It is sort of social networking. Users can register, add friends, upload images, videos. Also, they can search data. We are required to connect the two systems. One possible solution I think is - Adding components into our website. The component invoke services on the aggregators. - Synchronize website database to the aggregators. My doubts are: 1. How to add components in our websites? The components should use Java or Ruby or adapter from java to ruby. It is possible using ruby invoke web service. I think it should work since it is the point of web service. If so, can ruby call those services in wsdl directly? But how to deal with those different data structure? How to synchroinze our database to the aggregators. I think the best way is also through web service invocation such as upload. That means, we have to export the db records into xml files and then write some tools to upload. The web service project support MTOM. So, it is fine to upload huge data. Am I on the right record? Can anybody give me some hint. Thanks.

• What are the arguments against the inclusion of server side scripting in JavaScript code blocks?

  - by James Wiseman

  I've been arguing for some time against embedding server-side tags in JavaScript code, but was put on the spot today by a developer who seemed unconvinced The code in question was a legacy ASP application, although this is largely unimportant as it could equally apply to ASP.NET or PHP (for example). The example in question revolved around the use of a constant that they had defined in ServerSide code. 'VB Const MY_CONST: MY_CONST = 1 If sMyVbVar = MY_CONST Then 'Do Something End If //JavaScript if (sMyJsVar === "<%= MY_CONST%>"){ //DoSomething } My standard arguments against this are: Script injection: The server-side tag could include code that can break the JavaScript code Unit testing. Harder to isolate units of code for testing Code Separation : We should keep web page technologies apart as much as possible. The reason for doing this was so that the developer did not have to define the constant in two places. They reasoned that as it was a value that they controlled, that it wasn't subject to script injection. This reduced my justification for (1) to "We're trying to keep the standards simple, and defining exception cases would confuse people" The unit testing and code separation arguments did not hold water either, as the page itself was a horrible amalgam of HTML, JavaScript, ASP.NET, CSS, XML....you name it, it was there. No code that was every going to be included in this page could possibly be unit tested. So I found myself feeling like a bit of a pedant insisting that the code was changed, given the circumstances. Are there any further arguments that might support my reasoning, or am I, in fact being a bit pedantic in this insistence?
