• WebKit gets blank when clicking on the menu toolbar

  - by Miguel Ángel Ortuño

  Hi y'all. I've embebed a WebKit view into a modal dialog using Carbon and appereantly everything works fine. However there's a little problem. When I click on the menu toolbar the view gets completely blank getting visible only when I interact with it. Seems like the control stops reciving the 'paint window' event when I call MenuSelect function. All the events are managed by the parent window because of the nature of the application (videogame). Does anybody know what this behaviour is due to and how can I avoid it? Thanks for all.

• Server-side access to Client Browser's Latitude/Longitude using Django.

  - by ZenGyro

  Hello, So i am writing a little app that compares a user's position against a database on web-based server written using Django and performs some functions with it. Accessing the browser's geolocation data (in supported browsers ) is fairly trivial using JavaScript. But what is the best way to allow the Django server to access the longitude and latitude variables? Is it best to wrap them up as a JSON object and send to the server via POST? Or is there some easier (Geo)Django-based way to access the Navigator.geolocation browser object. Please forgive a newbie a question like this, but my Google-Fuing only seems to find ways to insert variables into JavaScript via template tag, whereas I need it to work the other way! Any advice or code snippets greatly appreciated. Feel free to talk to me like I am an idiot.

• mysql multiple where and inner join query combination

  - by bandhunt

  I'm a little lost as how to run two mysql queries as one(return one result set to be sorted etc). I understand how to do multiple JOINS but need to combine the below which is more than just a multiple join - it would include a multiple where etc. 1st query sql = "SELECT s.id, s.song_name FROM `songs` as s INNER JOIN `artists` as a ON s.artist_id = a.id WHERE ((`a`.id = #{search}))" 2nd query sql = "SELECT s.id, s.song_name FROM `songs` as s INNER JOIN `similarments` as si ON s.artist_id = si.artist_id WHERE ((`si`.similar_id = #{search}))" And then run both queries at once so I can ORDER them etc. Or combine them as one big query (maybe put an OR somewhere)? Thanks!

• Android remote code loading

  - by sehugg

  I am developing a library for Android that requires frequent updates from a central server. I was thinking how nice it would be if my library could update itself -- or if I could just release a bootstrap library that downloads the target library when the app is installed. I see this class in 1.5 called "DexClassLoader" but there seems to be precious little on the web besides the API docs. Has anyone used this successfully for the scenario which I described? Also, do the terms of the Android Market permit such a thing?

• Automatic release of objects when using Castle Windsor

  - by MotoSV

  Hi, I'm starting a new project and I'm looking into using a dependency container (Castle Windsor) to help when it comes to unit testing. One of the things that is a little frustrating is that after I've finished using an object I have to tell the container to "release" the object. I understand the reasoning behind doing this, but it's still cumbersome to have to remember to do this. So, my question is, is there a way I can make the "releasing" of an object automatic so I don't have to remember to release it? Kind Regards Michael

• What is the best way to read files in an EventMachine-based app?

  - by Theo

  In order not to block the reactor I would like to read files asynchronously, but I've found no obvious way of doing it using EventMachine. I've tried a few different approaches, but none of them feels right: Just read the file, it'll block the reactor, but what the hell, it's not that slow (unless it's a big file, and then it definitely is). Open the file for reading and read a chunk on each tick (but how much to read? too much and it'll block the reactor, too little and reading will get slower than necessary). EM.popen('cat some/file', FileReader) feels really weird, but works better than the alternatives above. In combination with the LineAndTextProtocol it reads lines pretty swiftly. EM.attach, but I haven't found any examples of how to use it, and the only thing I've found on the mailing list is that it's deprecated in favour of… EM.watch, which I've found no examples of how to use for reading files. How do you read files within a EventMachine reactor loop?

• C++0x, How do I expand a tuple into variadic template function arguments?

  - by Gustaf

  Consider the case of a templated function with variadic template arguments: template<typename Tret, typename... T> Tret func(const T&... t); Now, I have a tuple t of values. How do I call func() using the tuple values as arguments? I've read about the bind() function object, with call() function, and also the apply() function in different some now-obsolete documents. The GNU GCC 4.4 implementation seems to have a call() function in the bind() class, but there is very little documentation on the subject. Some people suggest hand-written recursive hacks, but the true value of variadic template arguments is to be able to use them in cases like above. Does anyone have a solution to is, or hint on where to read about it?

• Is a full list returned first and then filtered when using linq to sql to filter data from a databas

  - by RJ

  This is probably a very simple question that I am working through in an MVC project. Here's an example of what I am talking about. I have an rdml file linked to a database with a table called Users that has 500,000 rows. But I only want to find the Users who were entered on 5/7/2010. So let's say I do this in my UserRepository: from u in db.GetUsers() where u.CreatedDate = "5/7/2010" select u (doing this from memory so don't kill me if my syntax is a little off, it's the concept I am looking for) Does this statement first return all 500,000 rows and then filter it or does it only bring back the filtered list?

• What are the new features in Java 7

  - by T.K.

  What is the most official Java 7 feature list? I find very little useful information regarding this on the official JDK 7 site. Apart from that I can only find blogs with people summarizing "some" of the new features. However, some of these blog entries are old and some of them claim that these features "may or may not" be included in Java 7. Can anyone provide a list of features that will definitely be included in Java 7? I would also very much like to know the estimated release date. Will it be backwards compatible with my existing Java EE 6 stuff. That is, will I be able to switch seamlessly using EJBs, JPA2, Glassfish 3 and so on. The feature I am mostly interested in is Closures, so I'll happily switch to Java 7 as soon as a stable release comes out. Thanks!

• Automate downloads from password protected website

  - by Andrew

  I need some help with a work project I have been assigned. At the moment we manually go to the site, logon and then download 2 excel files from a supplier's website every month. The files are then loaded into SQL. We want to automate this process. Now the loading of the files into SQL I can do, but I am not sure how I can automate logging onto the website entering my user details and collecting the files. I mostly deal with SQL and have very little .NET experience, so any code samples would be most appreciated.

• Rails precision error

  - by dontangg

  When I run this in my Rails application: my_envelope.transactions.sum(:amount) This SQL is shown in the log files: SQL (0.3ms) SELECT SUM("transactions"."amount") AS sum_id FROM "transactions" WHERE (envelope_id = 834498537) And this value is returned: <BigDecimal:1011be570,'0.2515999999 9999997E2',27(27)> As you can see, the value is 25.159999. It should be 25.16. When I run the same SQL on the database myself, the correct value is returned. I'm a little confused because I know that there are precision problems with Floats, but it is returning a BigDecimal. The SQL column type is decimal. Any ideas?

• jQuery: What does (function($) {})(jQuery); mean?

  - by Legend

  I am just starting out with writing jQuery plugins. I wrote three small plugins but I have been simply copying the line into all my plugins without actually knowing what it means. Can someone tell me a little more about these? What does this do? (I know it extends jQuery somehow but is there anything else interesting to know about this) (function($) { })(jQuery); What is the difference between the following two ways of writing a plugin: Type 1: (function($) { $.fn.jPluginName = { }, $.fn.jPluginName.defaults = { } })(jQuery); Type 2: (function($) { $.jPluginName = { } })(jQuery); I could be way off here and maybe both mean the same thing. In some cases, this doesn't seem to be working in a plugin that I was writing using Type 1. Any idea why? But in either case, I would appreciate any explanation.

• Make C# source run as a script?

  - by acidzombie24

  I am doing a little scripting and i find some more power would be nice. Like the ability to keep trying to delete a file with a 1sec delay AND have it portable since i spent some time today translating a bat script to bash. I know i can use php or python but i VERY MUCH PREFER static/compile time checking. Is there a way to run C# code as a script? I am hoping i dont have to create a custom ext and write a app to dynamically compile and execute the script (i know have source to compile .js somewhere...). Does anyone know of a solution?

• Development enviroment for .NET

  - by user137348

  I'm about to create an development enviroment for a little developer company(3-4 developers + some testers). Our development platform is .NET and Oracle. My question is how to structure the whole enviroment.How many servers do I need ? Should be one server for developers and one for testers ? I'd like to have one build server (TeamCity). Where to put the Subversion ? Visual Studio's would be on developers laptops. Do I need one database for development and one extra for build server ? What else could be helpful ??

• Seam + hibernate + jsf on weblogic

  - by Kiva

  I'm making a little project with Seam, Hibernate and JSF. This project run on JBoss 5.1. My boss wants to deploy this project on WebLogic. I read on the seam documentation that seam and WebLogic don't work fine together. I would like to know if I can use Hibernate (with JPA) and JSF on WebLogic and what framework (struts, spring?) I can use to replace Seam. Edit: I read in the seam documentation (chapter 39, weblogic integration) and I find that: For several releases of Weblogic there has been an issue with how Weblogic generates stubs and compiles EJB's that use variable arguments in their methods. This is confirmed in the Weblogic 9.X and 10.0.MP1 versions. Unfortunately the 10.3 version only partially addresses the issue as detailed below. So, I want to know if other problems like this exist. Edit 2: I use Weblogic 10.3

• On Mac OS X, do you use the shipped python or your own?

  - by The MYYN

  On Tiger, I used a custom python installation to evaluate newer versions and I did not have any problems with that*. Now Snow Leopard is a little more up-to-date and by default ships with $ ls /System/Library/Frameworks/Python.framework/Versions/ 2.3 2.5 2.6 @Current What could be considered best practice? Using the python shipped with Mac OS X or a custom compiled version in, say $HOME. Are there any advantages/disadvantages using the one option over the other? My setup was fairly simple so far and looked like this: Custom compiled Python in $HOME and a $PATH that would look into $HOME/bin first, and subsequently would use my private Python version. Also $PYTHONPATH pointed to this local installation. This way, I did not need to sudo–install packages - virtualenv took care of the rest.

• PHP connection_aborted doesn't work with nginx?

  - by TheOnly92

  I can't seem to get the function connection_aborted to work with nginx. The code I used to test is as follow: <?php ignore_user_abort(true); ob_implicit_flush(); $i = 0; while (!connection_aborted()) { echo $i; $i++; sleep(1); } file_put_contents('test',$i); In Apache, it works correctly, although it delays a little. i.e. When I press stop button on browser when "3", the 'test' file shows "8". That is an acceptable margin, but on nginx, it doesn't seem to output anything to the 'test' file.

• Silverlight PRISM and 'loose' style files

  - by Suiva

  Hi, We are looking at starting a new Silverlight project using the PRISM framework (to benefit from modules etc) and I am still a little unclear about the best styling approach. What I'd ideally like is to have editable XAML files (maybe even just 1 for the whole project) containing the application's style so that they can be edited to change the look and feel of the application without having to recompile everything. Is this approach something people use? I guess it would need to load the file in at startup and apply the style which I assume wouldn't be a massive overhead. Just wondering what approaches people use Thanks for your time

• Byte order (endian) of int in NSLog?

  - by Eonil

  NSLog function accepts printf format specifiers. My question is about %x specifier. Does this print hex codes as sequence on memory? Or does it have it's own printing sequence style? unsigned int a = 0x000000FF; NSLog(@"%x", a); Results of above code on little or big endian processors are equal or different? And how about NSString's -initWithFormat method? Does it follows this rule equally?

• How to generate multiple Alter Scripts in SSMS

  - by dannyRods

  I'm using sql server management studio 2008 to try and generate an alter script for each of my stored procedures in order to save the scripts for each revision. I can easily generate an alter script for each individual procedure, but I'm not trying to go through a hundred stored procedures manually. I know that SSMS has an automated generate scripts function under task, but the only options are create, drop and create, and drop. I cant seem to figure out how to enable alter. I've already searched through many SO articles, as well as a little digging in msdn, and I've come up with nothing. I'm hoping that the fine people of stackoverflow will be up to the challenge. Thanks in advance

• do.call(rbind, list) for uneven number of column

  - by h.l.m

  I have a list, with each element being a character vector, of differing lengths I would like to bind the data as rows, so that the column names 'line up' and if there is extra data then create column and if there is missing data then create NAs Below is a mock example of the data I am working with x <- list() x[[1]] <- letters[seq(2,20,by=2)] names(x[[1]]) <- LETTERS[c(1:length(x[[1]]))] x[[2]] <- letters[seq(3,20, by=3)] names(x[[2]]) <- LETTERS[seq(3,20, by=3)] x[[3]] <- letters[seq(4,20, by=4)] names(x[[3]]) <- LETTERS[seq(4,20, by=4)] The below line would normally be what I would do if I was sure that the format for each element was the same... do.call(rbind,x) I was hoping that someone had come up with a nice little solution that matches up the column names and fills in blanks with NAs whilst adding new columns if in the binding process new columns are found...

• functions in assembler

  - by stupid_idiot

  hi, i have philosophised about the purpose of stack a little bit and after some coding i figured out what is it's strength. The only thing that lies in my stomache is how does it work with functions? I tried to make some easy function for adding two numbers using universal registers but I suppose that's not how does it work in C for example.. where are all the parameters, local variables and where is the result stored? how would you rewrite this to assembler?(how would compiler for C rewrite it?) int function(int a, int &b, int *c){ return a*(b++)+(*c); } i know this example kinda sucks.. but this way i can understand all the possibilities

• Strategy for desugaring Haskell

  - by luqui

  I'm developing a virtual machine for purely functional programs, and I would like to be able to test and use the the wide variety of Haskell modules already available. The VM takes as input essentially terms in the untyped lambda calculus. I'm wondering what would be a good way to extract such a representation from modern Haskell modules (eg. with MPTC's, pattern guards, etc.). I did a little research and there doesn't seem to be a tool that does this already (I would be delighted to be mistaken), and that's okay. I'm looking for an approach. GHC Core seems too operationally focused, especially since one of the things the VM does is to change the evaluation order significantly. Are there any accessible intermediate representations that correspond more closely to the lambda calculus?

• Why MSVS Create lib file every time?

  - by codevania

  The problem is that Visual Stuiod re-create lib everytime. How can I make MSVS does not re-create? I don't know why MSVS create some kind of project's "lib" file whenever I press F5 to debug application. I just converted a solution file from 2005 to 2010. And this problem is occured. [ Revival ] 1.Build solution. 2.Debug 3.Stop debug 4.No source code change 5.Debug (re-create lib) I think that re-creation lib is not necessary. Re-creation lib file takes just a second. But it is little annoying. I'm in desperate need of your help.

• Is there a JS/JQuery way to find out if embedded objects are loaded?

  - by Beska

  I've got a web page that I'm embedding a pdf into. Conceptually very simple: <html> <body> blah1 <object type="application/pdf" data="a.pdf" width="500" height="650" ></object> blah2 </body> </html> What I would like to do is fire a JavaScript event when the pdf finishes loading. Is there a way to make this happen? I know only a little about JQuery, but it looks like .ready() won't fit my needs, since it is designed to fire when the html document is ready, not when all of its components are fully loaded. Thoughts?
