Google Radar Chart: Not plotting data

- by Hallik

Hi. I have different types of data that I have normalized just with base10, so everything is on a 10 point scale. There are two data points, and the legend for them show up fine. All the points around the radar show up fine and so do the labels for them, but I don't see any filled in data. Outside of the labels and axis, the chart is blank. Below is the actual image tag I render, then I split up the variables on each line for easy readability. Anyone mind telling me why it isn't working? <img src="http://chart.apis.google.com/chart?cht=rs&chm=B,3366CC60,0,1.0,5.0|B,CC4D3360,1,1.0,5.0&chs=600x500&chd=t:4.6756775443385,4.7031365524912,1.8646655408171,1.8358167047079,4.2483837215455,4.1367786166752,|5.0319252700625,5.0370797208146,1.8415340693163,1.8591105937857,4.3392150450337,4.1434876641017&chco=3366CC,CC4D33&chls=2.0,4.0,0.0|2.0,4.0,0.0&chxt=x&chxl=0:|Label1|Label2|label3|Label4|Label5|Label6&chxr=0,0.0,10.0&chdl=Data Object 1|Data Object 2&"/> cht=rs& chm=B,3366CC60,0,1.0,5.0|B,CC4D3360,1,1.0,5.0& chs=600x500& chd=t:4.6756775443385,4.7031365524912,1.8646655408171,1.8358167047079,4.2483837215455,4.1367786166752,|5.0319252700625,5.0370797208146,1.8415340693163,1.8591105937857,4.3392150450337,4.1434876641017& chco=3366CC,CC4D33& chls=2.0,4.0,0.0|2.0,4.0,0.0& chxt=x& chxl=0:|Label1|Label2|label3|Label4|Label5|Label6& chxr=0,0.0,10.0& chdl=Data Object 1|Data Object 2& This is the radar chart page, I can't tell what I am doing wrong. http://code.google.com/apis/chart/docs/gallery/radar_charts.html

Adding BarButtons to a UINavigationBar after presenting a modal view controller.

- by yujean

I'm using the template for a "Utility Application". In the "FlipSideViewController", I added an IBOutlet for a UINavigationController, navController. In the code, I added the navController just fine. The rootViewController loads perfectly: navController.viewControllers = [[NSArray arrayWithObject:rootViewController] retain]; [self.view addSubview:navController.view]; I changed the color of the navController just fine: navController.navigationBar.tintColor = [UIColor colorWithRed:0.6 green:0.75 blue:0.6 alpha:1.0]; navController.navigationBar.translucent = NO; I make a button (note: "done" refers to a IBAction that dismisses the modalviewcontroller): UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"TEST" style:UIBarButtonItemStyleDone target:self action:@selector(done:)]; I make a navItem using that button: UINavigationItem *backNavItem = [[UINavigationItem alloc] initWithTitle:@"TESTTEST"]; [backNavItem setRightBarButtonItem:backButton animated:YES]; I try to add that button: [navController.navigationBar pushNavigationItem:backNavItem animated:YES]; This above code fails miserably. I apparently can't add buttons to the navController because: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Cannot call pushNavigationItem:animated: directly on a UINavigationBar managed by a controller.' Do I have to make a separate UINavigationBar that's somehow connected to my navController? I tried going that route but with no avail.

Vlad the deployer on Dreamhost - initial script

- by xmariachi

Hi, I'm trying to deploy an app with SVN and Vlad the deployer. Vlad and its dependencies are installed and seem OK. I'm trying the following: rake prod vlad:update Being my config/deploy.rb file: task :prod do set :application, "xxx" set :deploy_timestamped, "false" set :user, "username" set :scm_user, "scmusername" set :repository, "http://domain.com/svn/app" set :domain, "domain.com" set :deploy_to, "/home/username/deployments/app" puts "Production deployment to #{deploy_to}" end I have done "rake prod vlad:setup" already, that's fine. But when calling "rake prod vlad:update", I get the following A ...file Exported revision 14. ln: creating symbolic link `/home/username/deployments/drupalgestalt/releases/20100503164225/public/system' to `/home/username/deployments/drupalgestalt/shared/system': No such file or directory rake aborted! execution failed with status 1: ssh domain.com ln -s /home/username/deployments/app/shared/log /home/username/deployments/app/releases/20100503164225/log && ln -s /home/username/deployments/app/shared/system /home/username/deployments/app/releases/20100503164225/public/system && ln -s /home/username/deployments/app/shared/pids /home/username/deployments/app/releases/20100503164225/tmp/pids Apparently it complains when creating the ln, but permissions are all set up fine. Am I doing anything wrong? I'm just starting with Vlad on the assumption it was super-easy to set up. Had played a bit with cap in the past, and I do like Vlad idea.

Content-disposition:inline header won't show images inline?

- by hamstar

I'm trying to show an image inline on a page. It is being served by a codeigniter controller. class Asset extends MY_Controller { function index( $folder, $file ) { $asset = "assets/$folder/$file"; if ( !file_exists( $asset ) ) { show_404(); return; } switch ( $folder ) { case 'css': header('Content-type: text/css'); break; case 'js': header('Content-type: text/javascript'); break; case 'images': $ext = substr( $file, strrpos($file, '.') ); switch ( $ext ) { case 'jpg': $ext = 'jpeg'; break; case 'svg': $ext = 'svg+xml'; break; } header('Content-Disposition: inline'); header('Content-type: image/'.$ext); } readfile( $asset ); } } When I load a image in Chrome of FF its pops up the download window. I know when the browser can't display the content inline it will force a download anyway, but these are PNG and GIF images which display in the browser fine otherwise. In IE it doesn't force a download but it displays the image in ASCII. If I comment out the entire image case it FF and Chrome both display the ASCII but not the image. I thought setting the content type would allow FF and Chrome to show the actual image, and also allow the location to be used as an src. The javascript and css shows fine of course. Anyone got any ideas how I can make the images show properly? Thanks :)

XAML ContextMenu gets bound to wrong row in a DataGrid

- by Simon_Weaver

I have a XAML based ContextMenu bound to the rows in a datagrid. It works just fine - until the grid is scrolled! This is the context menu for one of the controls in the visual tree or a DataGrid row. <data:DataGridTemplateColumn Header="Customer Details" Width="*"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Grid Background="Transparent">  <controlsInputToolkit:ContextMenuService.ContextMenu> <controlsInputToolkit:ContextMenu> <controlsInputToolkit:MenuItem Header="{Binding CompletedOrderId,StringFormat='Create Reminder for order #\{0\}'}" CommandParameter="{Binding}"> <controlsInputToolkit:MenuItem.Command> <command:CreateReminderCommand/> </controlsInputToolkit:MenuItem.Command> <controlsInputToolkit:MenuItem.Icon> <Viewbox> <Image Width="19" Height="18" Source="../images/reminders.png" VerticalAlignment="Center"/> </Viewbox> </controlsInputToolkit:MenuItem.Icon> </controlsInputToolkit:MenuItem> <controlsInputToolkit:ContextMenu> <controlsInputToolkit:ContextMenuService.ContextMenu> ...... The ICommand is CreateReminderCommand and the CommandParameter is bound to the data item for the row itself. This works just fine - I can right click on a row and it will show me the correct text in the menu item 'Create Reminder for order 12345'. Then I scroll the datagrid down a page. If I keep right clicking on items then suddenly I'll see the wrong order number for a row. I think what must be happening is this : The DataGrid is reusing instances of MenuItem that it has previously created. How can I force a refresh of the ContextMenu when it is displayed for an item that changes? There's no 'Update method on the ContextMenu or ContextMenuService.

Appengine datastore phantom entity - inconsistent state?

- by aloo

Getting a weird error on java appengine code that used to work fine (nothing has changed but the data in the datastore). I'm trying to iterate over the results of a query and change a few properties of the entities. The query does return a set of results, however, when I try to access the first result in the list, it throws an exception when trying to access any of its properties (but its key). Here's the exception: org.datanucleus.state.JDOStateManagerImpl isLoaded: Exception thrown by StateManager.isLoaded Could not retrieve entity of kind OnTheCan with key OnTheCan(3204258) org.datanucleus.exceptions.NucleusObjectNotFoundException: Could not retrieve entity of kind OnTheCan with key OnTheCan(3204258) at org.datanucleus.store.appengine.DatastoreExceptionTranslator.wrapEntityNotFoundException(DatastoreExceptionTranslator.java:60) And here is my code: PersistenceManager pm = PMF.get().getPersistenceManager(); Query query = null; List<OnTheCan> cans; query = pm.newQuery("SELECT this FROM " + OnTheCan.class.getName() + " WHERE open == true ORDER BY onTheCanId ASC"); query.setRange(0, num); cans = (List<OnTheCan>) query.execute(); for (OnTheCan c : cans) { System.err.println(c.getOnTheCanId()); // this works fine! getting the key works c.setOpen(false); // failure here with the above exception c.setAutoClosed(true); c.setEndTime(new Date(c.getStartTime().getTime() + 600000/*10*60*1000*/)); } pm.close(); The code throws the exception when trying to execute c.setOpen(false) - thats the first time I'm accessing or setting a property that isnt the key. So it seems there is a phantom entity in my datastore with key 3204258. THis entity doesn't really exist (queried the datastore from admin console) but for some reason its being returned by the query. Could my data store be in an inconsistent state? I've managed the following workaround by placing it as the first line in my for loop. Clearly an ugly hack: if (c.getOnTheCanId() == 3204258) { continue; } Any ideas?

Netbeans and EOF

- by sqlnoob

Hey there, Java, ANTLR and Netbeans newbie here. I have installed a jdk and netbeans. I started a new project on netbeans 6.8 and i have added the antlr-3.2.jar as a library. I also created a lexer and parser class using AntlrWorks. These classes are named ExprParser.java and ExprLexer.java. I copied them into a directory named path-to-netbeans-project/src/parsers. I have a main file: package javaapplication2; import org.antlr.runtime.*; import parsers.*; public class Main { public static void main(String[] args) throws Exception{ ANTLRInputStream input = new ANTLRInputStream(System.in); ExprLexer lexer = new ExprLexer(input); CommonTokenStream tokens = new CommonTokenStream(lexer); ExprParser parser = new ExprParser(tokens); parser.prog(); } } The application builds fine. The book I'm reading says I should run the program and type in some stuff and then press Ctrl+Z (I'm on windows) to send EOF to the console. Problem is that nothing happens when I press Ctrl+z in the netbeans console. When I run from the command line, ctrl+z works fine. This is probably WAY too much information, but I can't figure it out. Sorry. Probably not a good idea to learn 3 new technologies at once.

Missing chars in JpGraph

- by Álvaro G. Vicario

I have a web site that runs on Windows and uses cp1252 (aka Win-1252) so it can display Spanish characters. The app generates some plots with JpGraph 2.3. These plots use the Tahoma Open Type font family to display text labels. Strings are provided in ANSI (i.e., cp1252) and font files support cp1252 (actually, the *.ttf files were copied from the system's font folder). It's been working fine in several setups from PHP/5.2.6 to PHP/5.3.0. Problems started when I ran the app under PHP/5.3.1: all non-ASCII are replaced by the hollow rectangle that represents missing or unknown chars. JpGraph's documentation is not very precise about how it expects international chars. Apparently, text is handled internally by the imagettftext() function, which expects UTF-8. However, encoding everything as UTF-8 breaks the app in all the systems. Where ANSI used to work fine, I get wrong characters (Ê instead of Ú). Where I got missing chars, now I get a PHP error: Warning: imagettftext(): any2eucjp(): something happen Do you have any clue about what changed in GD2 from PHP/5.3.0 to 5.3.1 that could be affecting the rendering on non-ASCII chars? How am I expected to feed JpGraph with strings in the Win-1252 charset?

Detect IE version in Javascript

- by Chad Decker

I want to bounce users of our web site to an error page if they're using a version of Internet Explorer prior to v9. It's just not worth our time and money to support IE pre-v9. Users of all other non-IE browsers are fine and shouldn't be bounced. Here's the proposed code: if(navigator.appName.indexOf("Internet Explorer")!=-1){ //yeah, he's using IE var badBrowser=( navigator.appVersion.indexOf("MSIE 9")==-1 && //v9 is ok navigator.appVersion.indexOf("MSIE 1")==-1 //v10, 11, 12, etc. is fine too ); if(badBrowser){ // navigate to error page } } Will this code do the trick? To head off a few comments that will probably be coming my way: [1] Yes, I know that users can forge their useragent string. I'm not concerned. [2] Yes, I know that programming pros prefer sniffing out feature-support instead of browser-type but I don't feel this approach makes sense in this case. I already know that all (relevant) non-IE browsers support the features that I need and that all pre-v9 IE browsers don't. Checking feature by feature throughout the site would be a waste. [3] Yes, I know that someone trying to access the site using IE v1 (or = 20) wouldn't get 'badBrowser' set to true and the warning page wouldn't be displayed properly. That's a risk we're willing to take. [4] Yes, I know that Microsoft has "conditional comments" that can be used for precise browser version detection. IE no longer supports conditional comments as of IE 10, rendering this approach absolutely useless. Any other obvious issues to be aware of? Thanks.

setAttribute, onClick and cross browser compatability...

- by Nicholas Kreidberg

I have read a number of posts about this but none with any solid answer. Here is my code: // button creation onew = document.createElement('input'); onew.setAttribute("type", "button"); onew.setAttribute("value", "hosts"); onew.onclick = function(){fnDisplay_Computers("'" + alines[i] + "'"); }; // ie onew.setAttribute("onclick", "fnDisplay_Computers('" + alines[i] + "')"); // mozilla odiv.appendChild(onew); Now, the setAttribute() method (with the mozilla comment) works fine in mozilla but only if it comes AFTER the line above it. So in other words it seems to just default to whichever gets set last. The .onclick method (with the ie comment) does not work in either case, am I using it incorrectly? Either way I can't find a way to make this work at all in IE, let alone in both. I did change the function call when using the .onclick method and it worked fine using just a simple call to an alert function which is why I believe my syntax is incorrect. Long story short, I can't get the onclick parameter to work consistently between IE/Mozilla. -- Nicholas

Touch coordinates in iPhone landscape mode app

- by gok

I am trying to make this landscape only iphone app. I only use this code for this purpose: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); } However when I click clip subviews checkbox from interface builder, the view is clipped from the middle. I also don't receive any touch events from outside of view bounds obviously. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint fingerPos = [[touches anyObject] locationInView:self.view]; NSLog(@"%f %f",fingerPos.x,fingerPos.y); } only prints for coordinates between 20 and 320 for X. But Y works fine. When i try to modify bounds by hand, everything works fine; View is positioned and shown correctly, printed coordinates are correct, I receive touch from all of the screen except between 0 and 20 for X. So Left side of the screen is unresponsive to touch events for only 20 pixels. Code I use to modify bounds: self.view.bounds = CGRectMake(-180.0f, 0.0f, 680.0f, 480.0f); What might be causing this? Weird!

Weird switch behavior in .NET 4

- by RaYell

I have a problem understanding what's causes the compilation error in the code below: static class Program { static void Main() { dynamic x = ""; var test = foo(x); if (test == "test") { Console.WriteLine(test); } switch (test) { case "test": Console.WriteLine(test); break; } } private static string foo(object item) { return "bar"; } } The error I get is in switch (test) line: A switch expression or case label must be a bool, char, string, integral, enum, or corresponding nullable type. Intellisence shows me that foo operation will be resolved on runtime, which is fine because I'm using a dynamic type as a param. However I don't understand how if condition compiles fine when switch doesn't. Code above is just simplified version of what I have in my application (VSTO) which appeared after migrating the app from VSTO3 to VSTO4 when one method in VSTO was changed to return dynamic type values instead of object. Can anyone give me an explanation what's the problem. I know how to resolve it but I'd like to understand what's happening.

ActiveMQ broker configuration error when specifying persistenceAdapter: "One of '{WC[##other:"http:/

- by Joe

I am setting up a simple ActiveMQ embedded broker. It works fine, until I try to configure a persistence adapter. I am basically just copying the configuration from http://activemq.apache.org/persistence.html#Persistence-ConfiguringKahaPersistence. When I add this configuration to my Spring configuration, like so: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amq="http://activemq.apache.org/schema/core" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core-5.3.0.xsd"> <amq:broker useJmx="true" persistent="true" brokerName="localhost"> <amq:transportConnectors> <amq:transportConnector name="vm" uri="vm://localhost"/> </amq:transportConnectors> <amq:persistenceAdapter> <amq:kahaPersistenceAdapter directory="activemq-data" maxDataFileLength="33554432"/> </amq:persistenceAdapter> </amq:broker> </beans> I get the error: cvc-complex-type.2.4.a: Invalid content was found starting with element 'amq:persistenceAdapter'. One of '{WC[##other:"http://activemq.apache.org/schema/core"]}' is expected. When I take out the amq:persistenceAdapter element, it works fine. The same error happens no matter which persistence adapter I include in the body, e.g. jdbc, journal, etc. Any help would be greatly appreciated. Thanks.

Apache rewrite rules redux

- by AlexanderJohannesen

I've got a REST framework that when plopped into any directory should Just Work(TM), and it seems to work fine when I've got projects in subdirectories, but not if it's in root. So, given a few example directories; / /project1 /bingo/project2 /hoopla/doopla/minor/project3 All of these works fine, except I'm getting "funnies"* when the project runs in the root directory (bit hard to explain, I suppose, but the second level rewrites are not working properly). Here's my attempt at a generic .htaccess file: RewriteEngine On RewriteRule ^static/ - [L] RewriteCond %{REQUEST_URI} ^$ RewriteRule .* ./ [R,L] RewriteRule ^index.php - [L] RewriteRule (.*) index.php?q=$1 [QSA,PT] (And yes, all projects have a subdirectory ./static which is ignored by rewrites) What I'm trying to achieve is a set of rewrite rules that work for most cases (which is, again, plonking the project in a directory the webserver serves). I'm not a rewrite rules wiz by a long shot, and any good advice and gotchas would be appreciated (and yes, I've gone through too many introductory articles. I need some serious juice.) More info on the funnies; my webserver has docroot in one spot (under /usr/share/apache2/default-site/), but a set of rules that says that /projects is pulled in from somewhere else that's not a subdirectory of docroot (/home/user/Projects/). When I go there, I get a list of /projects subdirectories, and if one of those subdirectories gets called (restmapp) with the proposed rewrite rules, I get ; The requested URL /home/user/Projects/restmapp/index.php was not found on this server.

Heroku taps push weirdness...

- by holden

I have the strangest experience using taps to move data between my machine and heroku. It works fine except that it seems to loose 0s directly behind the decimal place for my geo coordinates. Ie 50.0519322 for some reason gets set to 50.519322... no idea why. When I pull the data from the remote location ie. heroku db:pull... it works fine, all decimal places intact on my machine, however, when i push it back to the remote server it loses these zeros. Especially directly behind the decimal place, though I haven't noticed it elsewhere yet. At first I was storing the lat and lng as simply numeric but refined it to: change_column :places, :lat, :numeric, :precision => 15, :scale => 10 change_column :places, :lng, :numeric, :precision => 15, :scale => 10 With no result, any ideas what's going on? From the console on the remote server i get the lat as being: #<BigDecimal:2aebcc5967c0,'0.50519322E2',18(18)> and my machine as: #<BigDecimal:10232f7c8,'0.50519322E2',12(16)> which is also odd, the second one because it shows up as 50.0519322 when i edit it thru my view but when i do to_f via console it gives me 50.519322

java.lang.NoClassDefFoundError

edmx - The operation could not be completed - After adding Inheritance

- by vdh_ant

Hey guys I have an edmx model which I have draged 2 tables onto - One called 'File' and the other 'ApplicaitonFile'. These two tables have a 1 to 1 relationship in the database. If I stop here everything works fine. But in my model, I want 'ApplicaitonFile' to inherit from 'File'. So I delete the 1 to 1 relationship then configure 'ApplicaitonFile' from 'File' and then remove the FileId from 'ApplicaitonFile' which was the primary key. (Note I am following the instructions from here). If I leave the model open at this point everything is fine, but as soon as I close it, if I try and reopen it again I get the following error "The operation could not be completed". I have been searching for a solution and found this - http://stackoverflow.com/questions/944050/entity-model-does-not-load but as far as I can tell I don't have a duplicate InheritanceConnectors (although I don't know exactly what I'm looking for but I can't see anything out of the ordinary - like 2 connectors with the same name) and the relationship I originally have is a 1 to 1 not a 1 to 0..1 Any ideas???

Why does calling abort() on ajax request cause error in ASP.Net MVC (IE8)

- by user169867

I use jquery to post to an MVC controller action that returns a table of information. The user of the page triggers this by clicking on various links. In the event the user decides to click a bunch of these links in quick succession I wanted to cancel any previous ajax request that may not have finished. I've found that when I do this (although its fine from the client's POV) I will get errors on the web application saying that "The parameters dictionary contains a null entry for parameter srtCol of non-nullable type 'System.Int32'" Now the ajax post deffinately passes in all the parameters, and if I don't try and cancel the ajax request it works just fine. But if I do cancel the request by calling abort() on the XMLHttpRequest object that ajax() returns before it finishes I get the error from ASP.Net MVC. Example: //Cancel any pevious request if (req) { req.abort(); req = null; } //Make new request req= $.ajax({ type: 'POST', url: "/Myapp/GetTbl", data: {srtCol: srt, view: viewID}, success: OnSuccess, error: OnError, dataType: "html" }); I've noticed this only happen is IE8. In FF it seems to not cuase a problem. Does anyone know how to cancel an ajax request in IE8 without causing errors for MVC? Thanks for any help.

Website (jQuery) consistently crashes Internet Explorer (REALLY STUCK!)

- by Bradley Bell

Hey Guys. I posted this question yesterday, but haven't had a response. Basically, I'm totally stuck and clueless over crashing in Internet Explorer. The website now works fine in all browsers except internet explorer. The website is heavily reliant on jQuery and as far as I'm aware, I cant spot anything wrong with the script. Internet Explorer displays no errors and I don't know what I can possibly change. It displays fine, which would suggest that its nothing up with the CSS or HTML? I'm fairly sure it has to be the script, because it only crashes when you hover over one of the mouseover links. I'm already over the deadline and time is ticking! Its driving me crazy. I've uploaded it onto a test directory here: www.openyourheart.org.uk/test/index.html (I'll add the script/css links below as a comment, It wont let me post more than one here!) I would reaaly, really appreciate any help on this. I can also send the website compressed and post scripts here if required/preferred. Thanks in advance, Bradley

video streaming over http in blackberry

- by ysnky

hi all, while i was searching video player over http, i found the article which is located at this url; http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/Stream ing_media_-_Start_to_finish.html?nodeid=2456737&ve rnum=0 i can run by adding ";deviceside=true" at the end of url. it works fine in the jde4.5 simulator. it gets 3gp videos from my local server. i tested with 580kb files and works fine. but when i get the same file from my server (not local, real server) i have problems with big files (e.g 580 kb). it plays 180kb files (but sometimes it does not play this file either) but not plays 580kb file. and also i deployed my application to my 9000 device it sometimes plays small file (180kb) but never plays big file (580kb). why it plays if it is on my local file, not play in real world? i ve stucked for days. hope you help me. and also the code at the url given below is not work, the only code i ve found is the above. blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How_To _-_Play_video_within_a_BlackBerry_smartphone_appli cation.html?nodeid=1383173&vernum=0 btw, there is no method such as resize(long param) of CircularByteBuffer class. so i comment relavent line (buffer.resize(buffer.getSize() + (buffer.getSize() * percent / 100)); as shown below. public void increaseBufferCapacity(int percent) { if(percent < 0){ log(0, "FAILED! SP.setBufferCapacity() - " + percent); throw new IllegalArgumentException("Increase factor must be positive.."); } synchronized(readLock){ synchronized(connectionLock){ synchronized(userSeekLock){ synchronized(mediaIStream){ log(0, "SP.setBufferCapacity() - " + percent); //buffer.resize(buffer.getSize() + (buffer.getSize() * percent / 100)); this.bufferCapacity = buffer.getSize(); } } } } } thanks in advance.

MPMoviePlayerController - streaming works on 3GS, not on anything pre-3GS

- by Canada Dev

I am having some serious issues and annoyances with MPMoviePlayerController. In my app you can watch trailers for some movies in .mov format. I have tested with a friend and had users report that it does not work on their device, which are all 3G. I have tested on my own, a 3GS and playback works fine. I have tried on a 1st gen iPhone and it doesn't work. So I am lead to believe it's a memory issue, and that it's simply stopping the playback and returning to the previous screen. Below is the code I use to launch the player, which is straight out of the MoviePlayer example from Apple. MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:trailerURL]]; if (mp) { self.moviePlayer = mp; [mp release]; [self.moviePlayer play]; } I have tried to check the NSError from the notifications, but the only thing I get is "An unknown playback error occurred" for both the localizedDescription and localizedRecoverySuggestion, making it impossible to figure out exactly why it's not working. I have seen many examples of people who just have issues with the movie player, but it's starting to annoy me that it sometimes seem to work fine and other times it just doesn't (again, appearing like a memory issue). Thanks for any help/feedback provided

Failure to register .dll with regsvr32 - only in Release build.

- by Hendrik

Hi, I'm having a weird problem when trying to register the .dll i created using regsvr32. During development everything went fine, the debug version registers and works fine. Now i wanted to create a Release version, but that Version does not register anymore. regsvr32 comes up with the following error: The module "mpegsplitter.dll" failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified procedure could not be found. Some research brought me to the dependency walker, which does tell me this Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module. It also does show a dependency on "crtdll.dll" that the debug version does not have (The function view shows soem functions that normally should be in ole32.dll), which is colored red'ish. So far so good, i guess its somehow related to what the dependency walker shows there. But where do i go from here? How do i fix it? Any help would be greatly appreciated, that has been keeping me busy for several hours already. Thanks!
