• Global resources can't be resolved after publishing Website in VS2008

  - by Scoregraphic

  Hi there I have a web-project running in VS 2008. We have some global resource files (*.resx) in the App_GlobalResources folder for internationalisation. All this works like a charm on my local IIS installation out of VS. But when I publish my web-project to the local filesystem and/or another server, all the resources can no longer be found. So I guess the pre-compilation is somehow corrupting stuff. When I call the pre-compiled web, I get an error that the resource object with key xyz cannot be found, although it could be found before. I checked with .NET reflector if the resource stuff made it into the *.dlls. All those identifiers are there (bin/Web.dll, bin/<culture>/Web.resources.dll). The identifiers are loaded like this: <asp:MenuItem NavigateUrl="~/OrderNew.aspx" Text="<%$ Resources:MyProject, MenuNewOrder %>" Value="NewOrder"> The resource files are called MyProject.resx and MyProject.<culture>.resx where <culture> corresponds the the specific culture (i.e. MyProject.de-DE.resx). Any ideas how to solve this? I really appreciate any help. Thanks Edit: If I copy the App_GlobalResources folder manually to the output, the resources may be loaded normally. So I really really wonder what this pre-compilation is all about. I'm still interested in solving the issue "the right way".

• Putting a C++ Vector as a Member in a Class that Uses a Memory Pool

  - by Deep-B

  Hey, I've been writing a multi-threaded DLL for database access using ADO/ODBC for use with a legacy application. I need to keep multiple database connections for each thread, so I've put the ADO objects for each connection in an object and thinking of keeping an array of them inside a custom threadInfo object. Obviously a vector would serve better here - I need to delete/rearrange objects on the go and a vector would simplify that. Problem is, I'm allocating a heap for each thread to avoid heap contention and stuff and allocating all my memory from there. So my question is: how do I make the vector allocate from the thread-specific heap? (Or would it know internally to allocate memory from the same heap as its wrapper class - sounds unlikely, but I'm not a C++ guy) I've googled a bit and it looks like I might need to write an allocator or something - which looks like so much of work I don't want. Is there any other way? I've heard vector uses placement-new for all its stuff inside, so can overloading operator new be worked into it? My scant knowledge of the insides of C++ doesn't help, seeing as I'm mainly a C programmer (even that - relatively). It's very possible I'm missing something elementary somewhere. If nothing easier comes up - I might just go and do the array thing, but hopefully it won't come to that. I'm using MS-VC++ 6.0 (hey, it's rude to laugh! :-P ). Any/all help will be much appreciated.

• Does WordPress clear $GLOBALS ?

  - by Brayn

  Hey What I want to do is to include one of my PHP scripts in a Word Press theme. The problem is that after I include the script file I can't access, inside functions in the theme file, variables declared in the script file . I have created a new file in the theme folder and added the same code as in header.php and if I open that file it works just fine. So as far as I can tell it's something Word Press related. /other/path/wordpress/wp-content/themes/theme-name/header.php // this is broken /other/path/wordpress/wp-content/themes/theme-name/test.php // this works /var/www/vhosts/domain/wordpress/ ->(symlink)-> /other/path/wordpress/ /other/path/wordpress/wp-content/themes/theme-name/header.php /var/www/vhosts/domain/include_file.php Content of: /var/www/vhosts/domain/include_file.php $global_var = 'global'; print_r($GLOBALS); // if I open this file directly this prints globals WITH $global_var; // if this file is included in header this prints all the WP stuff WITHOUT $global_var; Content of: /other/path/wordpress/wp-content/themes/theme-name/header.php require '/path/to/include_file.php'; print $global_var; // this prints 'global' as expected function test() { global $global_var; print $global_var; // this is NULL } test(); print_r($GLOBALS); // this prints all the WP stuff WITHOUT $global_var in it

• How do I implement a listener pattern over RMI using Spring?

  - by predhme

  So here is a generalized version of our application desgin: @Controller public class MyController { @Autowired private MyServiceInterface myServiceInterface; @RequestMapping("/myURL") public @ResponseBody String doSomething() { MyListenerInterface listener = new MyListenerInterfaceImpl(); myServiceInterface.doThenCallListener(listener); // do post stuff } } public interface MyListenerInterface { public void callA(); public void callB(); } public class MyListenerInterfaceImpl implements MyListenerInterface { // ... omitted for clarity } public interface MyServiceInterface { public void doThenCallListener(MyListenerInterface listener); } public class MyServiceImpl { public void doThenCallListener(MyListenerInterface listener) { // do stuff listener.callA(); } } Basically I have a controller that is being called via AJAX in which I am looking to return a response as a string. However, I need to make a call to the backend (MyServiceInterface). That guy is exposed through RMI by using Spring (man that was easy). But the service method as described requires a listener to be registered for invokation completion purposes. So what I assume I need to achieve is transparently to the backend make it so that when the listener methods are called, really the call is going over RMI. I would have thought Spring would have a simple way to wrap a POJO (not a service singleton) with RMI calls. I looked through their documentation but they had nothing besides exposing services via RMI. Could someone point me in the right direction?

• OO Objective-C design with XML parsing

  - by brainfsck

  Hi, I need to parse an XML record that represents a QuizQuestion. The "type" attribute tells the type of question. I then need to create an appropriate subclass of QuizQuestion based on the question type. The following code works ([auto]release statements omitted for clarity): QuizQuestion *question = [[QuizQuestion alloc] initWithXMLString:xml]; if( [ [question type] isEqualToString:@"multipleChoiceQuestion"] ) { [myQuestions addObject:[[MultipleChoiceQuizQuestion alloc] initWithXMLString:xml]; } //QuizQuestion.m -(id)initWithXMLString:(NSString*)xml { self.type = ...// parse "type" attribute from xml // parse the rest of the xml } //MultipleChoiceQuizQuestion.m -(id)initWithXMLString:(NSString*)xml { if( self= [super initWithXMLString:xml] ) { // multiple-choice stuff } } Of course, this means that the XML is parsed twice: once to find out the type of QuizQuestion, and once when the appropriate QuizQuestion is initialized. To prevent parsing the XML twice, I tried the following approach: // MultipleChoiceQuizQuestion.m -(id)initWithQuizRecord:(QuizQuestion*)record { self=record; // record has already parsed the "type" and other parameters // multiple-choice stuff } However, this fails due to the "self=record" assignment; whenever the MultipleChoiceQuizQuestion tries to call an instance-method, it tries to call the method on the QuizQuestion class instead. Can someone tell me the correct approach for parsing XML into the appropriate subclass when the parent class needs to be initialized to know which subclass is appropriate?

• VirtualHosting doesn't work. Logs me in through previous session

  - by Pablo

  When I log in with one browser session, I have to log in, but when I open another session it has automatically logged me in (as if I've picked up session 1), this does not happen if I use http://192.168.0.9:9070 It forces me to log in each time. So I know the application is working, it's just the proxy server that seems to apply the loging to each session (from http://icerap.limeo.com). # ************************************************************************ # Start of My stuff <<<------------------------------------------------------ # ************************************************************************ #<Proxy *> #Order Deny,Allow #Deny from all #Allow from 192.168.0 #</Proxy> # blog <VirtualHost *:80> ServerName icerap.limeo.com ProxyPass / http://192.168.0.9:9070/ ProxyPassReverse / http://192.168.0.9:9070/ </VirtualHost> # www <VirtualHost *:80> ServerName helpdesk.limeo.com ProxyPass / http://192.168.0.9:9055/ ProxyPassReverse / http://192.168.0.9:9055/ </VirtualHost> # blog <VirtualHost *:80> ServerName IceCake.limeo.com ProxyPass / http://192.168.0.9:9000/ ProxyPassReverse / http://192.168.0.9:9000/ </VirtualHost> # End of Limeo stuff <<<------------------------------------------------------ # ************************************************************************

• Qt and variadic functions

  - by Noah Roberts

  OK, before lecturing me on the use of C-style variadic functions in C++...everything else has turned out to require nothing short of rewriting the Qt MOC. What I'd like to know is whether or not you can have a "slot" in a Qt object that takes an arbitrary amount/type of arguments. The thing is that I really want to be able to generate Qt objects that have slots of an arbitrary signature. Since the MOC is incompatible with standard preprocessing and with templates, it's not possible to do so with either direct approach. I just came up with another idea: struct funky_base : QObject { Q_OBJECT funky_base(QObject * o = 0); public slots: virtual void the_slot(...) = 0; }; If this is possible then, because you can make a template that is a subclass of a QObject derived object so long as you don't declare new Qt stuff in it, I should be able to implement a derived templated type that takes the ... stuff and turns it into the appropriate, expected types. If it is, how would I connect to it? Would this work? connect(x, SIGNAL(someSignal(int)), y, SLOT(the_slot(...))); If nobody's tried anything this insane and doesn't know off hand, yes I'll eventually try it myself...but I am hoping someone already has existing knowledge I can tap before possibly wasting my time on it.

• How should I start to play with 3D

  - by MarceloRamires

  I'm a developer for just about 6 months now, and since I enjoy programming I make a couple of little programs. I've startedmaking encripters, calculators, tools, stuff to play with DropBox (hehe), stuff that play with bitmaps, drawing graphics, and even a program to update the MSN display image according to the artwork of the music you're listening yo on iTunes. Now I kind of ran off ideas of programs to deal with information, and I've had an idea: play around with 3d! so I've read a little about it and figured I'd have to have good notions on position and math on point spacial position (which I do, from my 3d modelling experience), but I don't know how to use API's for it, so I've 'simulated' simple 3d with a simple program I've made (it's just a spinning cube, please, first one to open it, comment here stating that it's safe, i've got no reason to harm anyone's pc.) One of my other hobbies is 3d modelling (completly amateur) and I'd like to mix these hobbies together! Here are some questions: 1) What would be a nice 3d development tool for a .NET programmer like me? 2) Is there a way of using 3d models made in 3DS Max ? (I intend on modelling characters) 3) What knowledges should I have in order to render it, and move it areound ? 4) Which API should I use ? NOTE: Not a dupe, I'm asking for directions specific for .NET development possibly using 3ds MAX, and there's no question about it!

• Is it OK to use WPF assemblies in a web app?

  - by Chris

  I have an ASP.NET MVC 2 app targeting .NET 4 that needs to be able to resize images on the fly and write them to the response. I have code that does this and it works. I am using System.Drawing.dll. However, I want to enhance my code so that not only am I resizing the image, but I am dropping it from 24bpp down to 4bit grayscale. I could not, for the life of me, find code on how to do this with System.Drawing.dll. But I did find a bunch of WPF stuff. This is my working/sample code (runs in LinqPad). // Load the original 24 bit image var bitmapImage = new BitmapImage(); bitmapImage.BeginInit(); bitmapImage.UriSource = new Uri(@"C:\Temp\Resized\18_appa2_015.png", UriKind.Absolute); //bitmapImage.DecodePixelWidth = 600; bitmapImage.EndInit(); // Create the destination image var formatConvertedBitmap = new FormatConvertedBitmap(); formatConvertedBitmap.BeginInit(); formatConvertedBitmap.Source = bitmapImage; formatConvertedBitmap.DestinationFormat = PixelFormats.Gray4; formatConvertedBitmap.EndInit(); // Encode and dump the image to disk var encoder = new PngBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(formatConvertedBitmap)); using (var fileStream = File.Create(@"C:\Temp\Resized\18_appa2_015_s2.png")) { encoder.Save(fileStream); } It uses System.Xaml.dll, WindowsBase.dll, PresentationCore.dll, and PresentationFramework.dll. The namespaces used are: System.Windows.Controls, System.Windows.Media, and System.Windows.Media.Imaging. Is there any problem using these namespaces in my web application? It doesn't seem right. If anyone knows how to drop the bit depth without all this WPF stuff (which I barely understand, BTW) I would be thrilled to see that too.

• git crlf configuration in mixed environment

  - by Jonas Byström

  I'm running a mixed environment, and keep a central, bare repository where I pull and push most of my stuff. This centralized repository runs on Linux, and I check out to Windows XP/7, Mac and Linux. In all repositories I put the following line in my .git/config: [core] autocrlf = true I don't have the flag safecrlf=true anywhere. First time when I modify stuff on my one Windows machine (XP) there is no problem and when I look at the diff, it looks fine. But when I do the same on the other Windows machine (7), all lines are shown as changed but local line endings are \r\n as expected (when checked in a hex editor). The same applies to a MacOSX can. Sometimes I get the feeling that the different systems wrestle on line endings, but I can't be sure (I'm loosing track of all the times I change specific files). I didn't use to have the autocrlf set, but set the flag many months back. Could that be causing my current problems? Do I need to clone everything again to loose some old baggage? Or are there other things that needs configuring too? I tried git checkout -- . about a million times, but with no success.

• I can't find the cause of an "unchecked or unsafe operations" warning in Java.

  - by Peter

  Hello, as per the title I am struggling to find the cause of an "unchecked or unsafe operations" warning in some code. If I have the following code, it compiles without any warnings: public void test() { Set<String> mySet = new HashSet<String>(); Set<String> myNewSet = mySet; //do stuff } Now, if I change where mySet comes from, specifically as the result of a method call, I get the "unchecked yadda yadda" warning: public void test() { Set<String> myNewSet = this.getSet(); //do stuff } public Set getSet() { Set<String> set = new HashSet<String>(); return set; } I have tried and tried to work out what the problem is and I am completely stumped. The issue is present whether I use Sets or Lists. Why would the Set returned by the getSet method be any different to the Set in the first example? Any help would be greatly appreciated as while the warning isn't the end of the world, it is bugging the hell out of me! :( Regards

• How do I send text to a UITextView?

  - by Lee

  I'm new to iphone development. I'm a VB programmer who is trying to convert a VB application to an ipad app. I need some help with sending text to a UITextView. I want to first have a UIPickerView and then once the user hits a UIButton, a UITextView appears and the text is then generated by my source code code, line by line. The code would constantly be concatenating strings to the text. It would sort of go like this-- 1) User makes selections with UIPickerView. 2) User then hits UIButton. 3) UIPickerView is replaced on the screen with a UITextView. 4) The code does stuff. 5) The code adds the 1st line of text into the UITextView. 6) The code does more stuff. 7) The code then adds the 2nd line of text into the UITextView, retaining the 1st line that was already there. Steps 6 and 7 are repeated until the code is done. Does anyone know of any examples of this that I could look at? I am mostly interested in finding something like a youtube video, a webpage that explains the code or even a good book that covers this particular topic. I am finding that the sample codes that Apple has on this site goes over my head. In fact, I could probably benefit from a good book. But, I am looking for one that I would already know covers this particular topic, since it is so essential to the app that I am trying to build.

• why am I stuck on "Initiating update" when deploying to google

  - by michelle

  I've have not had any trouble deploying through eclipse until now. I'm guessing it might have to do with all the stuff I've added today a folder of .pdf and .tex files (in war/web-inf directory) a bit of JDO stuff and a servlet that reads the files in the directory and indexes them into the JDO Is there any way to find out what exactly is the problem? I currently get stuck at "Initiating update" and the stack trace say "ConnectionReset" Any helkp of imput will be appreciated, I really need to deploy this today, thanks! here's the deploy trace: Unable to update: java.net.SocketException: Connection reset at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection$6.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.net.www.protocol.http.HttpURLConnection.getChainedException(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at com.google.appengine.tools.admin.ServerConnection.getAuthCookie(ServerConnection.java:315) at com.google.appengine.tools.admin.ServerConnection.authenticate(ServerConnection.java:219) at com.google.appengine.tools.admin.ServerConnection.send(ServerConnection.java:145) at com.google.appengine.tools.admin.ServerConnection.post(ServerConnection.java:81) at com.google.appengine.tools.admin.AppVersionUpload.send(AppVersionUpload.java:427) at com.google.appengine.tools.admin.AppVersionUpload.beginTransaction(AppVersionUpload.java:241) at com.google.appengine.tools.admin.AppVersionUpload.doUpload(AppVersionUpload.java:98) at com.google.appengine.tools.admin.AppAdminImpl.update(AppAdminImpl.java:56) at com.google.appengine.eclipse.core.proxy.AppEngineBridgeImpl.deploy(AppEngineBridgeImpl.java:271) at com.google.appengine.eclipse.core.deploy.DeployProjectJob.runInWorkspace(DeployProjectJob.java:148) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Caused by: java.net.SocketException: Connection reset at java.net.SocketInputStream.read(Unknown Source) at java.io.BufferedInputStream.fill(Unknown Source) at java.io.BufferedInputStream.read1(Unknown Source) at java.io.BufferedInputStream.read(Unknown Source) at sun.net.www.http.HttpClient.parseHTTPHeader(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getHeaderFieldKey(Unknown Source) at com.google.appengine.tools.util.ClientCookieManager.readCookies(ClientCookieManager.java:123) at com.google.appengine.tools.admin.ServerConnection.connect(ServerConnection.java:340) at com.google.appengine.tools.admin.ServerConnection.getAuthCookie(ServerConnection.java:314) ... 11 more

• Posting forms to a 404 + HttpHandler in IIS7: why has all POST data gone missing?

  - by Rahul

  OK, this might sound a bit confusing and complicated, so bear with me. We've written a framework that allows us to define friendly URLs. If you surf to any arbitrary URL, IIS tries to display a 404 error (or, in some cases, 403;14 or 405). However, IIS is set up so that anything directed to those specific errors is sent to an .aspx file. This allows us to implement an HttpHandler to handle the request and do stuff, which involves finding the an associated template and then executing whatever's associated with it. Now, this all works in IIS 5 and 6 and, to an extent, on IIS7 - but for one catch, which happens when you post a form. See, when you post a form to a non-existent URL, IIS says "ah, but that url doesn't exist" and throws a 405 "method not allowed" error. Since we're telling IIS to redirect those errors to our .aspx page and therefore handling it with our HttpHandler, this normally isn't a problem. But as of IIS7, all POST information has gone missing after being redirected to the 405. And so you can no longer do the most trivial of things involving forms. To solve this we've tried using a HttpModule, which preserves POST data but appears to not have an initialized Session at the right time (when it's needed). We also tried using a HttpModule for all requests, not just the missing requests that hit 404/403;14/405, but that means stuff like images, css, js etc are being handled by .NET code, which is terribly inefficient. Which brings me to the actual question: has anyone ever encountered this, and does anyone have any advice or know what to do to get things working again? So far someone has suggested using Microsoft's own URL Rewriting module. Would this help solve our problem? Thanks.

• Updating Data through Objects

  - by Chacha102

  So, lets say I have a record: $record = new Record(); and lets say I assign some data to that record: $record->setName("SomeBobJoePerson"); How do I get that into the database. Do I..... A) Have the module do it. class Record{ public function __construct(DatabaseConnection $database) { $this->database = $database; } public function setName($name) { $this->database->query("query stuff here"); $this->name = $name; } } B) Run through the modules at the end of the script class Record{ private $changed = false; public function __construct(array $data=array()) { $this->data = $data; } public function setName($name) { $this->data['name'] = $name; $this->changed = true; } public function isChanged() { return $this->changed; } public function toArray() { return $this->array; } } class Updater { public function update(array $records) { foreach($records as $record) { if($record->isChanged()) { $this->updateRecord($record->toArray()); } } } public function updateRecord(){ // updates stuff } }

• How does one create and use a pointer to an array of an unknown number of structures inside a class?

  - by user1658731

  Sorry for the confusing title... I've been playing around with C++, working on a project to parse a game's (Kerbal Space Program) save file so I can modify it and eventually send it over a network. I'm stuck with storing an unknown number of vessels and crew members, so I need to have an array of unknown size. Is this possible? I figured having a pointer to an array would be the way to go. I have: class SaveFileSystem { string version; string UT; int activeVessel; int numCrew; ??? Crews; // !! int numVessels; ??? Vessels; // !! } Where Crews and Vessels should be arrays of structures: struct Crew { string name; //Other stuff }; struct Vessel { string name; //Stuff }; I'm guessing I should have something like: this->Crews = new ???; this->Vessels = new ???; in my constructor to initialize the arrays, and attempt to access it with: this->Crews[0].name = "Ship Number One"; Does this make any sense??? I'd expect the "???"'s to involve a mess of asterisk's, like "*struct (*)Crews" but I have no real idea. I've got normal pointers down and such, but this is a tad over my head... I'd like to access the structures like in the last snippet, but if C++ doesn't like that I could do pointer arithmetic. I've looked into vectors, but I have an unhealthy obsession with efficiency, and it really pains me how you don't know what's going on behind it.

• Truly declarative language?

  - by gjvdkamp

  Hi all, Does anyone know of a truly declarative language? The behaviour I'm looking for is kind of what Excel does, where I can define variables and formulas, and have the formula's result change when the input changes (without having set the answer again myself) The behaviour I'm looking for is best shown with this pseudo code: X = 10 // define and assign two variables Y = 20; Z = X + Y // declare a formula that uses these two variables X = 50 // change one of the input variables ?Z // asking for Z should now give 70 (50 + 20) I've tried this in a lot of languages like F#, python, matlab etc, but every time i try this they come up with 30 instead of 70. Wich is correct from an imperative point of view, but i'm looking for a more declerative behaviour if you know what i mean. And this is just a very simple calculation. When things get more difficult it should handle stuff like recursion and memoization automagically. The code below would obviously work in C# but it's just so much code for the job, i'm looking for something a bit more to the point without all that 'technical noise' class BlaBla{ public int X {get;set;} // this used to be even worse before 3.0 public int Y {get;set;} public int Z {get{return X + Y;}} } static void main(){ BlaBla bla = new BlaBla(); bla.X = 10; bla.Y = 20; // can't define anything here bla.X = 50; // bit pointless here but I'll do it anyway. Console.Writeline(bla.Z);// 70, hurray! } This just seems like so much code, curly braces and semicolons that add nothing. Is there a language/ application (apart from Exel) that does this? Maybe I'm no doing it right in the mentioned langauges, or I've completely missed an app that does just this. I prototyped a language/ application that does this (along with some other stuff) and am thinking of productizing it. I just can't believe it's not there yet. Don't want to waste my time. Thanks in advance, Gert-Jan

• HTML Submit button vs AJAX based Post (ASP.NET MVC)

  - by Graham

  I'm after some design advice. I'm working on an application with a fellow developer. I'm from the Webforms world and he's done a lot with jQuery and AJAX stuff. We're collaborating on a new ASP.MVC 1.0 app. He's done some pretty amazing stuff that I'm just getting my head around, and used some 3rd party tools etc. for datagrids etc. but... He rarely uses Submit buttons whereas I use them most of the time. He uses a button but then attaches Javascript to it that calls an MVC action which returns a JSON object. He then parses the object to update the datagrid. I'm not sure how he deals with server-side validation - I think he adds a message property to the JSON object. A sample scenario would be to "Save" a new record that then gets added to the gridview. The user doesn't see a postback as such, so he uses jQuery to disable the UI whilst the controller action is running. TBH, it looks pretty cool. However, the way I'd do it would be to use a Submit button to postback, let the ModelBinder populate a typed model class, parse that in my controller Action method, update the model (and apply any validation against the model), update it with the new record, then send it back to be rendered by the View. Unlike him, I don't return a JSON object, I let the View (and datagrid) bind to the new model data. Both solutions "work" but we're obviously taking the application down different paths so one of us has to re-work our code... and we don't mind whose has to be done. What I'd prefer though is that we adopt the "industry-standard" way of doing this. I'm unsure as to whether my WebForms background is influencing the fact that his way just "doesn't feel right", in that a "submit" is meant to submit data to the server. Any advice at all please - many thanks.

• Writing a VM - well formed bytecode?

  - by David Titarenco

  Hi, I'm writing a virtual machine in C just for fun. Lame, I know, but luckily I'm on SO so hopefully no one will make fun :) I wrote a really quick'n'dirty VM that reads lines of (my own) ASM and does stuff. Right now, I only have 3 instructions: add, jmp, end. All is well and it's actually pretty cool being able to feed lines (doing it something like write_line(&prog[1], "jmp", regA, regB, 0); and then running the program: while (machine.code_pointer <= BOUNDS && DONE != true) { run_line(&prog[machine.cp]); } I'm using an opcode lookup table (which may not be efficient but it's elegant) in C and everything seems to be working OK. My question is more of a "best practices" question but I do think there's a correct answer to it. I'm making the VM able to read binary files (storing bytes in unsigned char[]) and execute bytecode. My question is: is it the VM's job to make sure the bytecode is well formed or is it just the compiler's job to make sure the binary file it spits out is well formed? I only ask this because what would happen if someone would edit a binary file and screw stuff up (delete arbitrary parts of it, etc). Clearly, the program would be buggy and probably not functional. Is this even the VM's problem? I'm sure that people much smarter than me have figured out solutions to these problems, I'm just curious what they are!

• Jasmine testing coffeescript expect(setTimeout).toHaveBeenCalledWith

  In the process of learning Jasmine, I've come to this issue. I want a basic function to run, then set a timeout to call itself again... simple stuff. class @LoopObj constructor: -> loop: (interval) -> #do some stuff setTimeout((=>@loop(interval)), interval) But I want to test to make sure the setTimeout was called with the proper args describe "loop", -> xit "does nifty things", -> it "loops at a given interval", -> my_nifty_loop = new LoopObj interval = 10 spyOn(window, "setTimeout") my_nifty_loop.loop(interval) expect(setTimeout).toHaveBeenCalledWith((-> my_nifty_loop.loop(interval)), interval) I get this error: Expected spy setTimeout to have been called with [ Function, 10 ] but was called with [ [ Function, 10 ] ] Is this because the (-> my_nifty_loop.loop(interval)) function does not equal the (=>@loop(interval)) function? Or does it have something to do with the extra square brackets around the second [ [ Function, 10 ] ]? Something else altogther? Where have I gone wrong?

• Taking my ASP.NET from my local comp to the server

  - by Andrew G. Johnson

  Hi All, So I have been developing a small ASP.NET web app in C# for my company over the past few weeks and now I am trying to push it onto our Rackspace server. First step was to create a virtual directory because we want it to be www.ourdomain.com/appname/ and most of the stuff on ourdomain.com is currently in classic ASP. So I did this and then uploaded my stuff to the new folder. I *think* I did this at least semi-right because the error message I am getting is that nice puke color (ASP.NET style instead of classic ASP style) -- problem is it is generic and just saying runtime error. I tried just copy/pasting <customErrors mode="On" /> into the web.config file in the /appname/ directory but nothing changed So the actual questions are: How can I get a more descriptive error, when I was developing locally I just pushed the "play button" in VS2010 and it would either show me the app or tell me where I screwed up Is there anything else I'm doing wrong that may be causing this? If there's things I need to check lemme know!

• Java: extending Object class

  - by Fabio F.

  Hello, I'm writing (well, completing) an "extension" of Java which will help role programming. I translate my code to Java code with javacc. My compilers add to every declared class some code. Here's an example to be clearer: MyClass extends String implements ObjectWithRoles { //implements... is added /*Added by me */ public setRole(...){...} public ... /*Ends of stuff added*/ ...//myClass stuff } It adds Implements.. and the necessary methods to EVERY SINGLE CLASS you declare. Quite rough, isnt'it? It will be better if I write my methods in one class and all class extends that.. but.. if class already extends another class (just like the example)? I don't want to create a sort of wrapper that manage roles because i don't want that the programmer has to know much more than Java, few new reserved words and their use. My idea was to extends java.lang.Object.. but you can't. (right?) Other ideas? I'm new here, but I follow this site so thank you for reading and all the answers you give! (I apologize for english, I'm italian)

• Using Sphinx with a distutils-built C extension

  - by detly

  I have written a Python module including a submodule written in C: the module itself is called foo and the C part is foo._bar. The structure looks like: src/ foo/__init__.py <- contains the public stuff foo/_bar/bar.c <- the C extension doc/ <- Sphinx configuration conf.py ... foo/__init__.py imports _bar to augment it, and the useful stuff is exposed in the foo module. This works fine when it's built, but obviously won't work in uncompiled form, since _bar doesn't exist until it's built. I'd like to use Sphinx to document the project, and use the autodoc extension on the foo module. This means I need to build the project before I can build the documentation. Since I build with distutils, the built module ends up in some variably named dir build/lib.linux-ARCH-PYVERSION — which means I can't just hard-code the directory into a Sphinx' conf.py. So how do I configure my distutils setup.py script to run the Sphinx builder over the built module? For completeness, here's the call to setup (the 'fake' things are custom builders that subclass build and build_ext): setup(cmdclass = { 'fake': fake, 'build_ext_fake' : build_ext_fake }, package_dir = {'': 'src'}, packages = ['foo'], name = 'foo', version = '0.1', description = desc, ext_modules = [module_real])

• How to parse phpDoc style comment block with php?

  - by Reveller

  Please consider the following code with which I'm trying to parse only the first phpDoc style comment (noy using any other libraries) in a file (file contents put in $data variable for testing purposes): $data = " /** * @file A lot of info about this file * Could even continue on the next line * @author [email protected] * @version 2010-05-01 * @todo do stuff... */ /** * Comment bij functie bar() * @param Array met dingen */ function bar($baz) { echo $baz; } "; $data = trim(preg_replace('/\r?\n *\* */', ' ', $data)); preg_match_all('/@([a-z]+)\s+(.*?)\s*(?=$|@[a-z]+\s)/s', $data, $matches); $info = array_combine($matches[1], $matches[2]); print_r($info) This almose works, except for the fact that everything after @todo (including the bar() comment block and code) is considered the value of @todo: Array ( [file] => A lot of info about this file Could even continue on the next line [author] => [email protected] [version] => 2010-05-01 [todo] => do stuff... / /** Comment bij functie bar() [param] => Array met dingen / function bar() { echo ; } ) How does my code need to be altered so that only the first comment block is being parsed (in other words: parsing should stop after the first "*/" encountered?

• C ] How can I handle weird errors from calculating acos / sin / atan2?

  - by Phrixus

  Has anyone seen this weird value while handling sin / cos/ tan / acos.. math stuff? ===THE WEIRD VALUE=== -1.#IND00 ===================== void inverse_pos(double x, double y, double& theta_one, double& theta_two) { // Assume that L1 = 350 and L2 = 250 double B = sqrt(x*x + y*y); double angle_beta = atan2(y, x); double angle_alpha = acos((L2*L2 - B*B - L1*L1) / (-2*B*L1)); theta_one = angle_beta + angle_alpha; theta_two = atan2((y-L1*sin(theta_one)), (x-L1*cos(theta_one))); } This is the code I was working on. In a particular condition - like when x & y are 10 & 10, this code stores -1.#IND00 into theta_one & theta_two. It doesn't look like either characters or numbers :( Without a doubt, atan2 / acos / stuff are the problems. But the problem is, try and catch doesn't work either cuz those double variables have successfully stored some values in them. Moreover, the following calculations never complain about it and never break the program! I'm thinking of forcing to use this value somehow and make the entire program crash... So that I can catch this error.. Except for that idea, I have no idea how I should check whether these theta_one and theta_two variables have stored this crazy values. Any good ideas? Thank you in advance..
