• Java - Iterator: "Syntax error, parameterized types are only available if source level is 5.0"

  - by Helpme

  Hi! I'm purposely targeting Java OS 1.4.2 I'm trying to use an iterator combined with apache's POI to read an excel spreadsheet. The code runs perfectly in java 1.5, but in the 1.4.2 version I get the error listed in the question subject. the code is: Iterator myIter = null; it breaks on that line of code, which is clearly at the beginning of the application. I dont understand what needs to be done to correct this issue. Please let me know if you have any insight!

• Integrating 3rd-party forum software to member-based website

  - by john

  When using some existing forum software in a larger web-site, how easy is it to: 1)Make your site's login functionality log the user into the forum 2)Make your site's registration functionality create forum login data I suppose in a way it might be easier to ONLY use the forum's database for maintaining users, but that means trusting it with sensitive data. I'm planning an integration between an existing bespoke desktop app and a new bespoke web-site which should include forums. I don't know which forums will be used but I know the new web functionality won't be PHP-based. I figure that's not a big deal but I'm wondering if forums typically allow configuration of where they look for login data, to avoid duplicating this data into my DB and the forum DB.

• Override Java System.currentTimeMillis

  - by Mike Clark

  Is there a way, either in code or with JVM arguments, to override the current time, as presented via System.currentTimeMillis, other than manually changing the system clock on the host machine? A little background: We have a system that runs a number of accounting jobs that revolve much of their logic around the current date (ie 1st of the month, 1st of the year, etc) Unfortunately, a lot of the legacy code calls functions such as new Date() or Calendar.getInstance(), both of which eventually call down to System.currentTimeMillis. For testing purposes, right now, we are stuck with manually updating the system clock to manipulate what time and date the code thinks that the test is being run. So my question is: Is there a way to override what is returned by System.currentTimeMillis? For example, to tell the JVM to automatically add or subtract some offset before returning from that method? Thanks in advance!

• C++: warning: '...' declared with greater visibility than the type of its field '...::<anonymous>'

  - by Albert

  I'm getting these two warnings (with GCC 4.2 on MacOSX): /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154:0 /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154: warning: 'startMainLockDetector()::MainLockDetector' declared with greater visibility than the type of its field 'startMainLockDetector()::MainLockDetector::<anonymous' /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154:0 /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154: warning: 'startMainLockDetector()::MainLockDetector' declared with greater visibility than its base 'Action' In this code: struct Action { virtual ~Action() {} virtual int handle() = 0; }; static void startMainLockDetector() { /* ... */ struct MainLockDetector : Action { bool wait(Uint32 time) { /* ... */ } int handle() { /* ... */ } }; /* ... */ } I'm not exactly sure what these warnings mean (what visibility?) and how to fix them. (I really want the class MainLockDetector to be local for that function only.) I have already compiled the same code with a lot of other compilers (clang, GCC 3.*, GCC 4.0, GCC 4.4, etc) and never got any warning for this code.

• How do I get Mathematica to thread a 2-variable function over two lists, using functional programmin

  - by Leah Wrenn Berman

  Lets say I have a function f[x_, y_], and two lists l1, l2. I'd like to evaluate f[x,y] where x runs over the list l1 and y runs over the list l2, and I'd like to do it without having to make all pairs of the form {l1[[i]],l2[[j]]}. (Motivation: I'm trying to implement some basic Haskell programs in Mathematica. In particular, I'd like to be able to code the Haskell program isMatroid::[[Int]]->Bool isMatroid b =and[or[sort(union(xs\\[x])[y]'elem'b|y<-ys]|xs<-b,ys<-b, xs<-x] I think I can do the rest of it, if I can figure out the original question, but I'd like the code to be Haskell-like. Any suggestions for implementing Haskell-like code in Mathematica would be appreciated.)

• GUI system architecture?

  - by topright

  I'm designing GUI (graphical user interface) system for a game engine (C++). Idea is to create a heirarchy of GUI controllers like Focusable, Hoverable, Dragable etc. Every GUI component can attach multiple controllers, they modify component's behaviour. I think it gives flexible system and protects from code duplication. Different instances of the same GUI class can have different complex behaviours (may be, even change it dynamically), so this approach looks practical. The other choice is to add focused, hovered, dragged etc. flags in the base GUI component class. It looks like overhead and not that flexible. Another solution is to use Decorator pattern and wrap objects with FocusDecorator, HoverDecorator etc. Maintaining such system looks a bit harder. Question: What are pitfalls in my solution? May be you have seen a better approaches in GUI systems? What are the best ways of implementing such flexible complex system?

• Count How many lines in a Java String

  - by Simon Guo

  Need some compact code for counting how many lines in a string. It should be Java Code. And the string is separated by \r or \n will be considered as a separate line. For example, "Hello\nWorld\nThis\nIs\t" should return 4. The prototype is private static int countLines(String str) {...} Can someone provide a compact code? I have solution at here but it is too long, I think. Thank you.

• Jenkins merge dev branch to master with -Xtheir stategy

  - by Pandya M. Nandan

  In GIT Plugin, we can merge one branch to other on work space before the starting of Build. However, plugin does not provide -Xtheir strategy. Now i want dev branch to merge on master, validate test cases and if successful then only push back to master. Problem i face is that if there is a merge conflict, i want changes of dev branch to exits (i know i can use -Xtheirs manually). [Like i can check git as Source Code Management, but can;t use its Additional behavior 'Merge Before Build' ] However when i run the required code in Execute Shell Section of Jenkins Job, It does not works as required and fails with error: fatal: dev - not something we can merge Jenkins Job Code is echo Start of Build git checkout dev git checkout master git status git merge dev --no-commit echo End of Build I have also used them with bask -l -c "", but is same problem.

• How can i supply an AntiForgeryToken when posting JSON data using $.ajax ?

  - by HerbalMart

  I am using the code as below of this post: First i will an fill array variable with the correct values for the controller action. Using the code below i think it should be very straigtforward by just adding the following line to the javascript: data["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val(); The <%= Html.AntiForgeryToken() %> is at his right place and the action has a [ValidateAntiForgeryToken] But my controller action keeps saying: "Invalid forgery token" What am i doing wrong here? Code data["fiscalyear"] = fiscalyear; data["subgeography"] = $(list).parent().find('input[name=subGeography]').val(); data["territories"] = new Array(); $(items).each(function() { data["territories"].push($(this).find('input[name=territory]').val()); }); if (url != null) { $.ajax( { dataType: 'JSON', contentType: 'application/json; charset=utf-8', url: url, type: 'POST', context: document.body, data: JSON.stringify(data), success: function() { refresh(); } }); }

• What CPAN module can summarize Perl error logs?

  - by mithaldu

  I'm maintaining some website code that will soon dump all its errors and warnings into a log file. In order to make this a bit more pro-active I plan to parse this log file daily, summarize the warnings and errors (i.e. count the occurrence of each specific one and group by either warning/error) and then email this to the devs on the project. This would likely admittedly be rather trivial with a hash and some further fiddling, I wondered if there is a suitable module on CPAN that I could use to do this task. It would either be one that summarizes specifically Perl error/warnings logs or one that summarizes arbitrary text files. Any suggestions?

• Replacing Resource files on new BlackBerry app version

  - by Jeff

  Hello, I am maintaining an existing BlackBerry application (implemented as a MIDlet). The application contains a number of data files that get bundled with the app as resources. Some of these data files need to be updated for a new version of the app. When the user goes to install a new version of the application (via URL of Jad file), it prompts them with the following message "Persistent data exists for the application. Would you like to retain this data? " If the user selects "Yes", it looks like the app continues to use the old resource files. This is so surprising to me. First of all, am I losing my mind or will an upgrade really not overwrite existing resource files? Is there any way I can force it to? Thanks, Jeff

• "Compiling" content with short tags to var, without eval()

  - by Spot

  To start off, let me clear the air by saying we are aware of the dis/advantages to using short tag syntax in PHP. That is not what this question is about. Is there a way to "include" a file containing short tag code, into a variable, and have PHP actually parse the code? include/require obviously do not provide the data in a workable form, and output buffering does not parse the short tag code because it happens at runtime. Using eval() is simply not an option. Suggestions?

• Working with OAuth on Google with Python

  - by Dan Loewenherz

  I'm having a very frustrating time creating a valid signature for Google's OAuth implementation. I have narrowed it all down to the fact that my signature-generation code has an error of some sort; what it is I have no idea. This is the signature base string in its entirety: GET&https%3A%2F%2Fwww.google.com%2Faccounts%2FOAuthGetAccessToken&oauth_consumer_key%3Ddlosplayground.appspot.com%26oauth_nonce%3D72815d55697cb24301fab03e1f7f1d66%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1274327867%26oauth_token%3D4%252FX2cZ54JuseQbgRwzTBzZ7lqIwqof%26oauth_verifier%3Dihf0F2Fx%252FpnCmwbVQnk2xMre%26oauth_version%3D1.0 The OAuth Playground returns an oauth_signature of gF8qAfWjpdKjKb4KR%2FvA2Gy0vhU%3D. My code gives me ikMpIKJQJ58jseg%2BKPBTecjmYPE%3D, so obviously I'm doing something wrong. Here's my signature generation code (equivalent to that of the standard oauth.py library): binascii.b2a_base64(hmac.new(CONSUMER_SECRET, BASE_STRING, hashlib.sha1).digest())[:-1] Any thoughts?

• Ignoring generated files when using "Treat warnings as errors"

  - by krystan honour

  We have started a new project but also have this problem for an existing project. The problem is that when we compile with a warning level of 4 we also want to switch on 'Treat all warnings as errors' We are unable to do this at the moment because generated files (in particular reference.cs files) are missing things like XML comments and this generates a warning, we do not want to suppress the xml comment warnings totally out of all files just for specific types of files (namely generated code). I have thought of a way this could be achieved but am not sure if these are the best way to do this or indeed where to start :) My thinking is that we need to do something with T4 templates for the code that is generated such that it does fill in XML documentation for generated code. Does anyone have any ideas, currently I'm at well over 2k warnings (its a big project) :(

• Syntax error in SWIG using __thread keyword

  - by user366838

  I am trying to make some code thread safe for use with pthreads. This code is written in C++, but is linked to using SWIG. g++ compiles this correctly, but when swig tries to create a wrapper, I get: fast_alloc.hh:109: Error: Syntax error in input(3) The original, unsafe code that compiles correctly is: static void *freeLists[Num_Buckets]; and the error occurs when I change it to: static __thread void *freeLists[Num_Buckets]; I have made other parts thread safe adding "__thread", for example, this works: static __thread unsigned newCount[Num_Buckets];

• Lock HTML select element, allow value to be sent on submit

  - by ILMV

  I have a select box (for a customer field) on a complex order form, when the user starts to add lines to the order they should not be allowed to change the customer select box (unless all lines are deleted). My immediate thought was that I could use the disabled attribute, but when the box is disabled the selected value is no longer passed to the target. When the problem arose a while ago one of the other developers worked around this by looping through all the options and disabling all but the selected option, and sure enough the value was passed to the target and we've been using since. But now I'm looking for a proper solution, I don't want to loop through all the options because are data is expanding and it's starting to introduce performance issues. I'd prefer not to enable this / all the elements when the submit button is hit. How can I lock the input, whilst maintaining the selected option and passing that value to the target script? I would prefer a non-JavaScript solution if possible, but if needed we are running jQuery 1.4.2 so that could be used.

• How to detect exception when executing Javascript in NPAPI plugin?

  - by Jordfräs

  In a plug-in I am using NPN_Evaluate() to execute some Javascript. How can I detect wether the Javascript raises an exception? Basically I want to execute any piece of Javascript and get the result from it or detect if it raised an exception. I tried wrapping my Javascript code like this: try { // Injected Javascript code here } catch (exc) { exc; } That way the result from NPN_Evaluate() will be an NPObject* containing a property "message" with the exception message if something goes wrong. But how can I know that it is an exception? It might as well be a result from the injected Javascript code. Am I approaching this the wrong way? Can I detect an exception without catching it in Javascript and returning the exception as the result?

• An operator == whose parameters are non-const references

  - by Eduardo León

  I this post, I've seen this: class MonitorObjectString: public MonitorObject { // some other declarations friend inline bool operator==(/*const*/ MonitorObjectString& lhs, /*const*/ MonitorObjectString& rhs) { return lhs.fVal==rhs.fVal; } } Before we can continue, THIS IS VERY IMPORTANT: I am not questioning anyone's ability to code. I am just wondering why someone would need non-const references in a comparison. The poster of that question did not write that code. This was just in case. This is important too: I added both /*const*/s and reformatted the code. Now, we get back to the topic: I can't think of a sane use of the equality operator that lets you modify its by-ref arguments. Do you?

• Animating shorthand CSS properties with jQuery

  - by Giulio Piancastelli

  Chapter 3 of jQuery Novice to Ninja starts with a section about animating CSS properties, and its first example suggests the following code should expand padding and add a couple of borders to every paragraph in a page: $('document').ready(function() { $('p').animate({ padding: '20px', borderBottom: '3px solid #8f8f8f', borderRight: '3px solid #bfbfbf' }, 2000); }); However, while the code indeed works with the jQuery 1.4 library included in the downloadable examples archive for the book, it only animates padding when used alongside jQuery 1.6, forgetting the shorthand CSS properties for border-bottom and border-right altogether. What happened in the transition between 1.4 and 1.6, causing the removal of this functionality? Has it been placed in some plugin? Is it possible to run this code as it's written and get back the border animation? If not, how would you animate border properties using jQuery 1.6?

• Can you cast an object to one that implements an interface? (JAVA)

  - by DDP

  Can you cast an object to one that implements an interface? Right now, I'm building a GUI, and I don't want to rewrite the Confirm/Cancel code (A confirmation pop-up) over and over again. So, what I'm trying to do is write a class that gets passed the class it's used in and tells the class whether or not the user pressed Confirm or Cancel. The class always implements a certain interface. Code: class ConfirmFrame extends JFrame implements ActionListener { JButton confirm = new JButton("Confirm"); JButton cancel = new JButton("Cancel"); Object o; public ConfirmFrame(Object o) { // Irrelevant code here add(confirm); add(cancel); this.o = (/*What goes here?*/)o; } public void actionPerformed( ActionEvent evt) { o.actionPerformed(evt); } } I realize that I'm probably over-complicating things, but now that I've run across this, I really want to know if you can cast an object to another object that implements a certain interface.

• ruby block and returning something from block

  - by dorelal

  I am using ruby 1.8.7. p = lambda { return 10;} def lab(block) puts 'before' puts block.call puts 'after' end lab p Above code output is before 10 after I refactored same code into this def lab(&block) puts 'before' puts block.call puts 'after' end lab { return 10; } Now I am getting LocalJumpError: unexpected return. To me both the code are doing same thing. Yes in the first case I am passing a proc and in the second case I am passing a block. But &block converts that block into proc. So proc.call should behave same. And yes I have seen this post http://stackoverflow.com/questions/2325471/using-return-in-a-ruby-block
