• Rebuilding old (2010) django project in 2012

  - by birgit

  I am trying to make an old Django project run again. After seemingly having solved issues with old sorl.thumbnail versions and deprecated expressions I now get this error when running python manage.py runserver I also tried to copy & paste my old files into a new Django project and get the exactly same error. Maybe someone here has a clue where the problem lies? Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x2a80510>> Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/django/core/management/commands/runserver.py", line 88, in inner_run self.validate(display_num_errors=True) File "/usr/lib/python2.7/dist-packages/django/core/management/base.py", line 249, in validate num_errors = get_validation_errors(s, app) File "/usr/lib/python2.7/dist-packages/django/core/management/validation.py", line 35, in get_validation_errors for (app_name, error) in get_app_errors().items(): File "/usr/lib/python2.7/dist-packages/django/db/models/loading.py", line 146, in get_app_errors self._populate() File "/usr/lib/python2.7/dist-packages/django/db/models/loading.py", line 61, in _populate self.load_app(app_name, True) File "/usr/lib/python2.7/dist-packages/django/db/models/loading.py", line 78, in load_app models = import_module('.models', app_name) File "/usr/lib/python2.7/dist-packages/django/utils/importlib.py", line 35, in import_module __import__(name) File "/home/me/Documents/wdws/wdws/../wdws/cityofwindows/models.py", line 73, in <module> class Image(models.Model): File "/home/me/Documents/wdws/wdws/../wdws/cityofwindows/models.py", line 83, in Image 'large': {'size': (640, 640)}, File "/usr/lib/python2.7/dist-packages/django/db/models/fields/files.py", line 233, in __init__ super(FileField, self).__init__(verbose_name, name, **kwargs) TypeError: __init__() got an unexpected keyword argument 'extra_thumbnails' I need to re-build the project just for visual documentation locally... so also any hints on how to quickly re-run outdated django-projects are very welcome!! Thanks a lot (using Ubuntu 12.04)

• Database Structure for CakePHP Models

  - by Michael T. Smith

  We're building a data tracking web app using CakePHP, and I'm having some issues getting the database structure right. We have Companies that haveMany Sites. Sites haveMany DataSamples. Tags haveAndBelongToMany Sites. That is all set up fine. The problem is "ranking" the sites within tags. We need to store it in the database as an archive. I created a Rank model that is setup like this: rank ( id (int), sample_id (int), tag_id (int), site_id (int), rank (int), total_rows) ) So, the question is, how do I create the associations for tag, site and sample to rank? I originally set them as haveMany. But the returned structures don't get me where I'd like to be. It looks like: [Site] => Array ( [Sample] = Array(), [Tag] = Array() ) When I'm really looking for: [Site] => Array ( [Tag] = Array ( [Sample] => Array ( [Rank] => Array ( ...data... ) ) ) ) I think that I may not be structuring the database properly; so if I need to update please let me know. Otherwise, how do I write a find query that gets me where I need to be? Thanks! Thoughts? Need more details? Just ask!

• Apache mod_rewrite - forward domain root to subdirectory

  - by DuFace

  I have what I originally assumed to be a simple problem. I am using shared hosting for my website (so I don't have access to the Apache configuration) and have only been given a single folder to store all my content in. This is all well and good but it means that all my subdomains must have their virtual document root's inside public_html, meaning they effectively become a folder on my main domain. What I'd like to do is organise my public_html something like this: public_html/ www/ index.php ... sub1/ index.php ... some_library/ ... This way, all my web content is still in public_html but only a small fraction of it will be served to the client. I can easily achieve this for all the subdomains, but it's the primary domain that I'm having issues with. I created a .htaccess file in public_html with the following: Options +SymLinksIfOwnerMatch # I'm not allowed to use FollowSymLinks RewriteEngine on RewriteBase / RewriteCond %{REQUEST_URI} !^/www [NC] RewriteRule ^(.*)$ /www/$1 [L] This works fairly well, but for some strange reason www.example.com/stuff is translated into a request for www.example.com/www/stuff and hence a 404 error is given. It was my understanding that unless an 'R' flag was specified, mod_rewrite was purely internal so I can't understand why the request is generated as that implies (to me at least) redirection. I assumed this would be a trivial problem to solve as all I actually want to do is forward all requests for the root of www.example.com to a subdirectory, but I've spent hours searching for answers and none are quite correct. I find it difficult to believe I'm the only person to have this issue. I apologise if this question has been answered on here before, I did search and trawl but couldn't find an appropriate answer. Please could someone shed some light on this?

• Clearing Session in Global Application_Error

  - by Zarigani

  Whenever an unhandled exception occurs on our site, I want to: Send a notification email Clear the user's session Send the user to a error page ("Sorry, a problem occurred...") The first and last I've had working for a long time but the second is causing me some issues. My Global.asax.vb includes: Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs) ' Send exception report Dim ex As System.Exception = Nothing If HttpContext.Current IsNot Nothing AndAlso HttpContext.Current.Server IsNot Nothing Then ex = HttpContext.Current.Server.GetLastError End If Dim eh As New ErrorHandling(ex) eh.SendError() ' Clear session If HttpContext.Current IsNot Nothing AndAlso HttpContext.Current.Session IsNot Nothing Then HttpContext.Current.Session.Clear() End If ' User will now be sent to the 500 error page (by the CustomError setting in web.config) End Sub When I run a debug, I can see the session being cleared, but then on the next page the session is back again! I eventually found a reference that suggests that changes to session will not be saved unless Server.ClearError is called. Unfortunately, if I add this (just below the line that sets "ex") then the CustomErrors redirect doesn't seem to kick in and I'm left with a blank page? Is there a way around this?

• VB.NET class inherits a base class and implements an interface issue (works in C#)

  - by 300 baud

  I am trying to create a class in VB.NET which inherits a base abstract class and also implements an interface. The interface declares a string property called Description. The base class contains a string property called Description. The main class inherits the base class and implements the interface. The existence of the Description property in the base class fulfills the interface requirements. This works fine in C# but causes issues in VB.NET. First, here is an example of the C# code which works: public interface IFoo { string Description { get; set; } } public abstract class FooBase { public string Description { get; set; } } public class MyFoo : FooBase, IFoo { } Now here is the VB.NET version which gives a compiler error: Public Interface IFoo Property Description() As String End Interface Public MustInherit Class FooBase Private _Description As String Public Property Description() As String Get Return _Description End Get Set(ByVal value As String) _Description = value End Set End Property End Class Public Class MyFoo Inherits FooBase Implements IFoo End Class If I make the base class (FooBase) implement the interface and add the Implements IFoo.Description to the property all is good, but I do not want the base class to implement the interface. The compiler error is: Class 'MyFoo' must implement 'Property Description() As String' for interface 'IFoo'. Implementing property must have matching 'ReadOnly' or 'WriteOnly' specifiers. Can VB.NET not handle this, or do I need to change my syntax somewhere to get this to work?

• FluentNHibernate: Not.Nullable() doesn't affect output schema

  - by alex

  Hello I'm using fluent nhibernate v. 1.0.0.595. There is a class: public class Weight { public virtual int Id { get; set; } public virtual double Value { get; set; } } I want to map it on the following table: create table [Weight] ( WeightId INT IDENTITY NOT NULL, Weight DOUBLE not null, primary key (WeightId) ) Here is the map: public class WeightMap : ClassMap<Weight> { public WeightMap() { Table("[Weight]"); Id(x => x.Id, "WeightId"); Map(x => x.Value, "Weight").Not.Nullable(); } } The problem is that this mapping produces table with nullable Weight column: Weight DOUBLE null Not-nullable column is generated only with default convention for column name (i.e. Map(x = x.Value).Not.Nullable() instead of Map(x = x.Value, "Weight").Not.Nullable()), but in this case there will be Value column instead of Weight: create table [Weight] ( WeightId INT IDENTITY NOT NULL, Value DOUBLE not null, primary key (WeightId) ) I found similiar problem here: http://code.google.com/p/fluent-nhibernate/issues/detail?id=121, but seems like mentioned workaround with SetAttributeOnColumnElement("not-null", "true") is outdated. Does anybody encountered with this problem? Is there a way to specify named column as not-nullable?

• ActiveMq integration with Spring 2.5

  - by Tony

  I am using ActiveMq 5.32 with Spring 2.5.5. I use pretty generic configuration, as long as I include the jmsTransactionManager in DefaultMessageListenerContainer, Spring throw an error on start up: "Error creating bean with name 'org.springframework.jms.listener.DefaultMessageListenerContainer#0'" Without the transactionManager attribute , this works fine, but when I add 10 messages to the message queue, a transaction exception will occur. Part of my configurations : <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="emailDestination" /> <property name="messageListener" ref="emailServiceMDP" /> <property name="transactionManager" ref="jmsTransactionManager" /> </bean> <bean id="jmsTransactionManager" class="org.springframework.jms.connection.JmsTransactionManager"> <property name="connectionFactory" ref="connectionFactory" /> </bean> Does this version of Spring and Activemq has some know issues in integration ? Or do I need additional libs to get jmsTransactionManager to work ?

• Why does animate not work for the first few 'selections' of my next button?

  - by Josiah

  I'll just start right off the bat and say I'm fairly new to JQuery, so if you see some glaring issues with my code....let me know what I'm doing wrong! Either way, I've been working on a script to fade divs in and out using the z-index and animate. It "works" after about 2-3 clicks, but the first two clicks do not fade or animate as I was hoping....why is that? I'll just throw javascript up here, but if you need/want more code, just let me know. Thanks! $(document).ready(function() { //Slide rotation/movement variables var first = $('#main div.slide:first').attr('title'); var last = $('#main div.slide').length; //Needed for the next/prev buttons var next; //Set the first div to the front, and variable for first div var $active = $('#main div.slide[title='+first+']'); //Hide the links until the div is hovered over and take them away when mouse leaves $('#main').children('a').hide(); $('#main').mouseenter(function() { $('#main').children('a').fadeIn(750); }).mouseleave(function() { $('#main').children('a').fadeOut(750); }); $active.css('z-index', '4'); $('#main #next').click(function() { if ((next = parseInt($active.attr('title')) + 1) > last) { next = 1; } $active.css('z-index', '0').stop().animate({opacity: 0}, 1000); $active = $('#main div[title='+next+']').css('z-index', '4').stop().animate({opacity : 1}, 1000); }); });

• C/C++ I18N mbstowcs question

  - by bogertron

  I am working on internationalizing the input for a C/C++ application. I have currently hit an issue with converting from a multi-byte string to wide character string. The code needs to be cross platform compatible, so I am using mbstowcs and wcstombs as much as possible. I am currently working on a WIN32 machine and I have set the locale to a non-english locale (Japanese). When I attempt to convert a multibyte character string, I seem to be having some conversion issues. Here is an example of the code: int main(int argc, char** argv) { wchar_t *wcsVal = NULL; char *mbsVal = NULL; /* Get the current code page, in my case 932, runs only on windows */ TCHAR szCodePage[10]; int cch= GetLocaleInfo( GetSystemDefaultLCID(), LOCALE_IDEFAULTANSICODEPAGE, szCodePage, sizeof(szCodePage)); /* verify locale is set */ if (setlocale(LC_CTYPE, "") == 0) { fprintf(stderr, "Failed to set locale\n"); return 1; } mbsVal = argv[1]; /* validate multibyte string and convert to wide character */ int size = mbstowcs(NULL, mbsVal, 0); if (size == -1) { printf("Invalid multibyte\n"); return 1; } wcsVal = (wchar_t*) malloc(sizeof(wchar_t) * (size + 1)); if (wcsVal == NULL) { printf("memory issue \n"); return 1; } mbstowcs(wcsVal, szVal, size + 1); wprintf(L"%ls \n", wcsVal); return 0; } At the end of execution, the wide character string does not contain the converted data. I believe that there is an issue with the code page settings, because when i use MultiByteToWideChar and have the current code page sent in EX: MultiByteToWideChar( CP_ACP, 0, mbsVal, -1, wcsVal, size + 1 ); in place of the mbstowcs calls, the conversion succeeds. My question is, how do I use the generic mbstowcs call instead of teh MuliByteToWideChar call?

• NSTask Launch causing crash

  - by tripskeet

  Hi, I have an application that can import an XML file through this terminal command : open /path/to/main\ app.app --args myXML.xml This works great with no issues. And i have used Applescript to launch this command through shell and it works just as well. Yet when try using Cocoa's NSTask Launcher using this code : NSTask *task = [[NSTask alloc] init]; [task setLaunchPath:@"/usr/bin/open"]; [task setCurrentDirectoryPath:@"/Applications/MainApp/InstallData/App/"]; [task setArguments:[NSArray arrayWithObjects:[(NSURL *)foundApplicationURL path], @"--args", @"ImportP.xml", nil]]; [task launch]; the applications will start up to the initial screen and then crash when either the next button is clicked or when trying to close the window. Ive tried using NSAppleScript with this : NSAppleScript *script = [[NSAppleScript alloc] initWithSource:@"tell application \"Terminal\" do script \"open /Applications/MainApp/InstallData/App/Main\\\\ App.app\" end tell"]; NSDictionary *errorInfo; [script executeAndReturnError:&errorInfo]; This will launch the program and it will crash as well and i get this error in my Xcode debug window : 12011-01-04 17:41:28.296 LaunchAppFile[4453:a0f] Error loading /Library/ScriptingAdditions/Adobe Unit Types.osax/Contents/MacOS/Adobe Unit Types: dlopen(/Library/ScriptingAdditions/Adobe Unit Types.osax/Contents/MacOS/Adobe Unit Types, 262): no suitable image found. Did find: /Library/ScriptingAdditions/Adobe Unit Types.osax/Contents/MacOS/Adobe Unit Types: no matching architecture in universal wrapper LaunchAppFile: OpenScripting.framework - scripting addition "/Library/ScriptingAdditions/Adobe Unit Types.osax" declares no loadable handlers. So with research i came up with this : NSAppleScript *script = [[NSAppleScript alloc] initWithSource:@"do shell script \"arch -i386 osascript /Applications/MainApp/InstallData/App/test.scpt\""]; NSDictionary *errorInfo; [script executeAndReturnError:&errorInfo]; But this causes the same results as the last command. Any ideas on what causes this crash?

• Any problems with this C++ const reference accessor interface idiom?

  - by mskfisher

  I was converting a struct to a class so I could enforce a setter interface for my variables. I did not want to change all of the instances where the variable was read, though. So I converted this: struct foo_t { int x; float y; }; to this: class foo_t { int _x; float _y; public: foot_t() : x(_x), y(_y) { set(0, 0.0); } const int &x; const float &y; set(int x, float y) { _x = x; _y = y; } }; I'm interested in this because it seems to model C#'s idea of public read-only properties. Compiles fine, and I haven't seen any problems yet. Besides the boilerplate of associating the const references in the constructor, what are the downsides to this method? Any strange aliasing issues? Why haven't I seen this idiom before?

• Iteration over a linq to sql query is very slow.

  - by devzero

  I have a view, AdvertView in my database, this view is a simple join between some tables (advert, customer, properties). Then I have a simple linq query to fetch all adverts for a customer: public IEnumerable<AdvertView> GetAdvertForCustomerID(int customerID) { var advertList = from advert in _dbContext.AdvertViews where advert.Customer_ID.Equals(customerID) select advert; return advertList; } I then wish to map this to modelItems for my MVC application: public List<AdvertModelItem> GetAdvertsByCustomer(int customerId) { List<AdvertModelItem> lstAdverts = new List<AdvertModelItem>(); List<AdvertView> adViews = _dataHandler.GetAdvertForCustomerID(customerId).ToList(); foreach(AdvertView adView in adViews) { lstAdverts.Add(_advertMapper.MapToModelClass(adView)); } return lstAdverts; } I was expecting to have some performance issues with the SQL, but the problem seems to be with the .ToList() function. I'm using ANTS performance profiler and it reports that the total runtime of the function is 1.400ms, and 850 of those is with the ToList(). So my question is, why does the tolist function take such a long time here?

• Why doesn't my UIViewController class keep track of an NSArray instance variable.

  - by TaoStoner

  Hey, I am new to Objective-C 2.0 and Xcode, so forgive me if I am missing something elementary here. Anyways, I am trying to make my own UIViewController class called GameView to display a new view. To work the game I need to keep track of an NSArray that I want to load from a plist file. I have made a method 'loadGame' which I want to load the correct NSArray into an instance variable. However it appears that after the method executes the instance variable loses track of the array. Its easier if I just show you the code.... @interface GameView : UIViewController { IBOutlet UIView *view IBOutlet UILabel *label; NSArray *currentGame; } -(IBOutlet)next; -(void)loadDefault; ... @implementation GameView - (IBOutlet)next{ int numElements = [currentGame count]; int r = rand() % numElements; NSString *myString = [currentGame objectAtIndex:(NSUInteger)r]; [label setText: myString]; } - (void)loadDefault { NSDictionary *games; NSString *path = [[NSBundle mainBundle] bundlePath]; NSString *finalPath = [path stringByAppendingPathComponent:@"Games.plist"]; games = [NSDictionary dictionaryWithContentsOfFile:finalPath]; currentGame = [games objectForKey:@"Default"]; } when loadDefault gets called, everything runs perfectly, but when I try to use the currentGame NSArray later in the method call to next, currentGame appears to be nil. I am also aware of the memory management issues with this code. Any help would be appreciated with this problem.

• What are salesforce.com and Apex like as an application development platform?

  - by mhollers

  I have recently discovered that salesforce.com is much more than an online CRM after coming across a Morrison's Case Study in which they develop a works management application. I've been trying it out with a view to recreating our own Works Management system on the platform. My background is in Microsoft and .Net, and the obvious 1st choice would be asp.net. However, there's only really myself with .net experience and my manager with a more legacy Synergy programming background, and I am self taught and am looking at evaluating other RAD options (eg Ironspeed). the nature of the business is in the main 2-5 concurrent construction type contracts that run for 3-5 yrs each, each requiring 15-50 system users. Traditionally we have used our character based Works Mangement system for everything and tweaked it for each contract. The Salesforce licensing model on the face of it suits this sort of flexibilty, but I'm worried about the development flexibilty/learning curve and all the issues that surround lock-in. There doesn't seem to be much neutral sober analysis of the platform on the web that isn't salesforce's own material/blogs Has anyone any experience of developing an application on salesforce as compared to the more 'traditional' .Net route?

• Starting an STA thread, but with parameters to the final function

  - by DRapp

  I'm a bit weak on how some delegates behave, such as passing a method as the parameter to be invoked. While trying to do some NUnit test scripts, I have something that I need to run many test with. Each of these tests requires a GUI created and thus the need for an STA thread. So, I have something like public class MyTest { // the Delegate "ThreadStart" is part of the System.Threading namespace and is defined as // public delegate void ThreadStart(); protected void Start_STA_Thread(ThreadStart whichMethod) { Thread thread = new Thread(whichMethod); thread.SetApartmentState(ApartmentState.STA); //Set the thread to STA thread.Start(); thread.Join(); } [Test] public void Test101() { // Since the thread issues an INVOKE of a method, I'm having it call the // corresponding "FromSTAThread" method, such as Start_STA_Thread( Test101FromSTAThread ); } protected void Test101FromSTAThread() { MySTA_RequiredClass oTmp = new MySTA_RequiredClass(); Assert.IsTrue( oTmp.DoSomething() ); } } This part all works fine... Now the next step. I now have a different set of tests that ALSO require an STA thread. However, each "thing" I need to do requires two parameters... both strings (for this case). How do I go about declaring proper delegate so I can pass in the method I need to invoke, AND the two string parameters in one shot... I may have 20+ tests to run with in this pattern and may have future of other similar tests with different parameter counts and types of parameters too. Thanks.

• Converting Source ASCII Files to JPEGs

  - by CommonsWare

  I publish technical books, in print, PDF, and Kindle/MOBI, with EPUB on the way. The Kindle does not support monospace fonts, which are kinda useful for source code listings. The only way to do monospace fonts is to convert the text (Java source, HTML, XML, etc.) into JPEG images. More specifically, due to pagination issues, a given input ASCII file needs to be split into slices of ~6 lines each, with each slice turned into a JPEG, so listings can span a screen. This is a royal pain. My current mechanism to do that involves: Running expand to set a consistent 2-space tab size, which pipes to... a2ps, which pipes to... A small Perl snippet to add a "%%LanguageLevel: 3\n" line, which pipes to... ImageMagick's convert, to take the (E)PS and make a JPEG out it, with an appropriate background, cropped to 575x148+5+28, etc. That used to work 100% of the time. It now works 95% of the time. The rest of the time, I get convert: geometry does not contain image errors, which I cannot seem to get rid of, in part because I don't understand what the problem is. Before this process, I used to use a pretty-print engine (source-highlight) to get HTML out of the source code...but then the only thing I could find to convert the HTML into JPEGs was to automate screen-grabs from an embedded Gecko engine. Reliability stank, which is why I switched to my current mechanism. So, if you were you, and you needed to turn source listings into JPEG images, in an automated fashion, how would you do it? Bonus points if it offers some sort of pretty-print process (e.g., bolded keywords)! Or, if you know what typically causes convert: geometry does not contain image, that might help. My current process is ugly, but if I could get it back to 100% reliability, that'd be just fine for now. Thanks in advance!

• C++ File manipulation problem

  I am trying to open a file which normally has content, for the purpose of testing i will like to initialize the program without the files being available/existing so then the program should create empty ones, but am having issues implementing it.

Could anybody explain me what to do in order to fix the problem. Thanks!

• How to write a JOIN statement to combine data from disparate tables

• How to parse (infinite) nested object notation?

  - by kyogron

  I am currently breaking my head about transforming this object hash: "food": { "healthy": { "fruits": ['apples', 'bananas', 'oranges'], "vegetables": ['salad', 'onions'] }, "unhealthy": { "fastFood": ['burgers', 'chicken', 'pizza'] } } to something like this: food:healthy:fruits:apples food:healthy:fruits:bananas food:healthy:fruits:oranges food:healthy:vegetables:salad food:healthy:vegetables:onions food:unhealthy:fastFood:burgers food:unhealthy:fastFood:chicken food:unhealthy:fastFood:pizza In theory it actually is just looping through the object while keeping track of the path and the end result. Unfortunately I do not know how I could loop down till I have done all nested. var path; var pointer; function loop(obj) { for (var propertyName in obj) { path = propertyName; pointer = obj[propertyName]; if (pointer typeof === 'object') { loop(pointer); } else { break; } } }; function parse(object) { var collection = []; }; There are two issues which play each out: If I use recurse programming it looses the state of the properties which are already parsed. If I do not use it I cannot parse infinite. Is there some idea how to handle this? Regards

• VS ASP.NET 500 Server Error

  - by rlb.usa

  Hey guys, I'm having a super weird problem with my VS 2008 solution. We had this hand-coded ASP.NET compiled web app on our old IIS6/Win2003 server, working great, moved it to our new IIS7/Win2008 server, still working great, but when I try to compile the application and publish it again to our new Win2008 server, I get server 500 errors. It's ASP.NET 2.0 with AJAX extensions and AJAX control toolkit. I'm not too great with server issues, or even sure if it is a server issue but here are some more symptoms... ? I know the website works (it only differs by some minor code fixes) and can use it's code on a development machine, there are no errors, and it publishes fine. Publishing (using the DLL files), and even not publishing and trying to use the code-behind files on our new server, both no success. The old website does work on the new server just fine. If I put a simple hello world html page in the website's virtual directory, with the old code, it works fine, but with the new code, that html page gets the 500 error. And in fact, oddly, I can add all the files to the website, only when I add the web.config, do I get the 500 error. The web.config has not changed. Tried stopping and restarting IIS What's the problem, here? Any ideas, what else can I do to troubleshoot the problem?

• File size monitoring in C#

  - by manemawanna

  Hello, I work in the Systems & admin team and have been given the task of creating a quota management application to try and encourage users to better manage there resources as we currently have issues with disc space and don't enforce hard quotas. At the moment I'm using the code below to go through all the files in a users homespace to retrieve the overall amount of space they are using. As from what I've seen else where theres no other way to do this in C#, the issue with it is theirs quite a high overhead while it retireves the size of each file then creates a total. try { long dirSize = 0; FileInfo[] FI = new DirectoryInfo("I:\\").GetFiles("*.*", SearchOption.AllDirectories); foreach (FileInfo F1 in FI) { dirSize += F1.Length; } return dirSize; } So I'm looking for a quicker way to do this or a quick way to monitor changes in the size of files while using the options avaliable through FileSystemWatcher. At the moment the only thing I can think of is creating a hashtable containing the file location and size of each file, so when a size changed event occurs I can compare the old size against the new one and update the total. Any suggestions would be greatly appreciated.

• Continuous Flash music player while navigating site

  - by phx-zs

  I have a site that includes a Flash music player integrated into the layout. I want users to be able to navigate around the site without interrupting the music. I've done plenty of research and thinking and the following are the options I came up with (keeping in mind I want to be as SEO friendly as possible). Anyone have another idea? AJAX: I set up a version that changes the main content div to whatever nav link they click, thereby not interrupting the Flash player. I set it up in the proper search-engine-friendly manner with direct links and JQuery/Ajax functions. If someone goes to site.com/ and clicks the Contact nav link, it loads what's in the main content div on site.com/contact.php into the main content div and changes the URL bar to site.com/#Contact. The same goes for if they go to site.com/contact.php and click About in the nav, it loads the About content and changes the URL bar to site.com/contact.php#About. Obviously this opens up a whole new can of worms with AJAX and hash navigation/history issues, and I would end up with people possibly linking to things like site.com/contact.php#About (which I think looks terrible and can't be too great for SEO). Store the Flash player vars somewhere and reload them with the page: I'm not sure how to go about this, but I thought about keeping my regular navigation without AJAX and have it so when a user clicks a nav link, before it changes pages it stores the Flash player vars (current song and song position) somewhere, then loads them into Flash when the new page loads. Something with an iframe? Good alternative to a Flash player that will work for this type of application? Thanks!

• Java string to double conversion.

  - by wretrOvian

  Hi, I've been reading up on the net about the issues with handling float and double types in java. Unfortunately, the image is still not clear. Hence, i'm asking here direct. :( My MySQL table has various DECIMAL(m,d) columns. The m may range from 5 to 30. d stays a constant at 2. Question 1. What equivalent data-type should i be using in Java to work (i.e store, retrieve, and process) with the size of the values in my table? (I've settled with double - hence this post). Question 2. While trying to parse a double from a string, i'm getting errors Double dpu = new Double(dpuField.getText()); for example - "1" -> java.lang.NumberFormatException: empty String "10" -> 1.0 "101" -> 10.0 "101." -> 101.0 "101.1" -> 101.0 "101.19" -> 101.1 What am i doing wrong? What is the correct way to convert a string to a double value? And what measures should i take to perform operations on such values?

• Simple question about the lunarlander example.

  - by Smills

  I am basing my game off the lunarlander example. This is the run loop I am using (very similar to what is used in lunarlander). I am getting considerable performance issues associated with my drawing, even if I draw almost nothing. I noticed the below method. Why is the canvas being created and set to null each cycle? @Override public void run() { while (mRun) { Canvas c = null; try { c = mSurfaceHolder.lockCanvas();//null synchronized (mSurfaceHolder) { updatePhysics(); doDraw(c); } } finally { // do this in a finally so that if an exception is thrown // during the above, we don't leave the Surface in an // inconsistent state if (c != null) { mSurfaceHolder.unlockCanvasAndPost(c); } } } } Most of the times I have read anything about canvases it is more along the lines of: mField = new Bitmap(...dimensions...); Canvas c = new Canvas(mField); My question is: why is Google's example done that way (null canvas), what are the benefits of this, and is there a faster way to do it?

• Can this code cause a memory leak (Arduino)

  - by tbraun89

  I have a arduino project and I created this struct: struct Project { boolean status; String name; struct Project* nextProject; }; In my application I parse some data and create Project objects. To have them in a list there is a pointer to the nextProject in each Project object expect the last. This is the code where I add new projects: void RssParser::addProject(boolean tempProjectStatus, String tempData) { if (!startProject) { startProject = true; firstProject.status = tempProjectStatus; firstProject.name = tempData; firstProject.nextProject = NULL; ptrToLastProject = &firstProject; } else { ptrToLastProject->nextProject = new Project(); ptrToLastProject->nextProject->status = tempProjectStatus; ptrToLastProject->nextProject->name = tempData; ptrToLastProject->nextProject->nextProject = NULL; ptrToLastProject = ptrToLastProject->nextProject; } } firstProject is an private instance variable and defined in the header file like this: Project firstProject; So if there actually no project was added, I use firstProject, to add a new one, if firstProject is set I use the nextProject pointer. Also I have a reset() method that deletes the pointer to the projects: void RssParser::reset() { delete ptrToLastProject; delete firstProject.nextProject; startProject = false; } After each parsing run I call reset() the problem is that the memory used is not released. If I comment out the addProject method there are no issues with my memory. Someone can tell me what could cause the memory leak?
