• Silverlight ViewBase in separate assembly - possible?

  - by Mark

  I have all my views in a project inheriting from a ViewBase class that inherits from UserControl. In my XAML I reference it thus: <f:ViewBase x:Class="Forte.UI.Modules.Configure.Views.AddNewEmployeeView" xmlns:f="clr-namespace:Forte.UI.Modules.Configure.Views" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" It works fine. Now I have moved the ViewBase to another project (so I can refernce it from multiple projects) so I reference it like: <f:ViewBase x:Class="Forte.UI.Modules.Configure.Views.AddNewEmployeeView" xmlns:f="clr-namespace:Forte.UI.Modules.Common.Views;assembly=Forte.UI.Modules.Common" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" This works fine when I run from the IDE but when I run the same sln from MSBuild it gives a warning: "H:\dev\ExternalCopy\Code\UI\Modules\Configure\Forte.UI.Modules.Configure.csproj" (default target) (10:12) - (ValidateXaml target) - H:\dev\ExternalCopy\Code\UI\Modules\Configure\Views\AddNewEmployee\AddNewEmployeeView.xaml(1,2,1,2): warning : The tag 'ViewBase' does not exist in XML namespace 'clr-namespace:Forte.UI.Modules.Common.Views;assembly=Forte.UI.Modules.Common'. Then fails with: "H:\dev\ExternalCopy\Code\UI\Modules\Configure\Forte.UI.Modules.Configure.csproj" (default target) (10:12) - (ValidateXaml target) - C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.Common.targets(210,9): error MSB4018: The "ValidateXaml" task failed unexpectedly.\r C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.Common.targets(210,9): er ror MSB4018: System.NullReferenceException: Object reference not set to an instance of an object.\r C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.Common.targets(210,9): er ror MSB4018: at MS.MarkupCompiler.ValidationPass.ValidateXaml(String fileName, Assembly[] assemb lies, Assembly callingAssembly, TaskLoggingHelper log, Boolean shouldThrow)\r C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.Common.targets(210,9): er ror MSB4018: at Microsoft.Silverlight.Build.Tasks.ValidateXaml.XamlValidator.Execute()\r C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.Common.targets(210,9): er ror MSB4018: at Microsoft.Silverlight.Build.Tasks.ValidateXaml.XamlValidator.Execute()\r C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.Common.targets(210,9): er ror MSB4018: at Microsoft.Silverlight.Build.Tasks.ValidateXaml.Execute()\r C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.Common.targets(210,9): er ror MSB4018: at Microsoft.Build.BuildEngine.TaskEngine.ExecuteInstantiatedTask(EngineProxy engin eProxy, ItemBucket bucket, TaskExecutionMode howToExecuteTask, ITask task, Boolean& taskResult) Any ideas what might be causing this behaviour? Using Silverlight 3 Here is a cut down version of the MSBuild file that fails to build the sln that builds fine in the IDE (sorry couldn't get it to format here): <?xml version="1.0" encoding="utf-8" ?> <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="Compile"> <ItemGroup> <ProjectToBuild Include="..\UI\Forte.UI.sln"> <Properties>Configuration=Debug</Properties> </ProjectToBuild> </ItemGroup> <Target Name="Compile"> <MSBuild Projects="@(ProjectToBuild)"></MSBuild> </Target> </Project> Thanks for any help!

• Redirect output logs of javax.xml.ws and com.sun.xml.ws

  - by chrisnfoneur

  I am working on a SOAP based web service, with Sun's Metro. I am facing an annoying bug, each time I send a malformed SOAP object to my web service, sun's api spam the System.out with logs like this: javax.xml.ws.WebServiceException: com.sun.istack.XMLStreamException2: org.xml.sax.SAXParseException: cvc-complex-type.4: Attribute 'type' must appear on element 'object'. at com.sun.xml.ws.util.pipe.AbstractSchemaValidationTube.doProcess(AbstractSchemaValidationTube.java:206) at com.sun.xml.ws.util.pipe.AbstractSchemaValidationTube.processRequest(AbstractSchemaValidationTube.java:175) at com.sun.xml.ws.api.pipe.Fiber.__doRun(Fiber.java:595) at com.sun.xml.ws.api.pipe.Fiber._doRun(Fiber.java:554) at com.sun.xml.ws.api.pipe.Fiber.doRun(Fiber.java:539) at com.sun.xml.ws.api.pipe.Fiber.runSync(Fiber.java:436) at com.sun.xml.ws.server.WSEndpointImpl$2.process(WSEndpointImpl.java:243) at com.sun.xml.ws.transport.http.HttpAdapter$HttpToolkit.handle(HttpAdapter.java:444) at com.sun.xml.ws.transport.http.HttpAdapter.handle(HttpAdapter.java:244) at com.sun.xml.ws.transport.http.server.WSHttpHandler.handleExchange(WSHttpHandler.java:106) at com.sun.xml.ws.transport.http.server.WSHttpHandler.handle(WSHttpHandler.java:91) at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:65) at sun.net.httpserver.AuthFilter.doFilter(AuthFilter.java:54) at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:68) at sun.net.httpserver.ServerImpl$Exchange$LinkHandler.handle(ServerImpl.java:555) at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:65) at sun.net.httpserver.ServerImpl$Exchange.run(ServerImpl.java:527) at sun.net.httpserver.ServerImpl$DefaultExecutor.execute(ServerImpl.java:119) at sun.net.httpserver.ServerImpl$Dispatcher.handle(ServerImpl.java:349) at sun.net.httpserver.ServerImpl$Dispatcher.run(ServerImpl.java:321) at java.lang.Thread.run(Thread.java:619) Caused by: com.sun.istack.XMLStreamException2: org.xml.sax.SAXParseException: cvc-complex-type.4: Attribute 'type' must appear on element 'object'. at com.sun.xml.ws.util.xml.StAXSource$1.parse(StAXSource.java:185) at com.sun.xml.ws.util.xml.StAXSource$1.parse(StAXSource.java:170) at org.apache.xerces.jaxp.validation.ValidatorHandlerImpl.validate(Unknown Source) at org.apache.xerces.jaxp.validation.ValidatorImpl.validate(Unknown Source) at javax.xml.validation.Validator.validate(Validator.java:127) at com.sun.xml.ws.util.pipe.AbstractSchemaValidationTube.doProcess(AbstractSchemaValidationTube.java:204) ... 20 more I would like to switch off this log or redirect it to my error/warn/debug.log files used by log4j. I tried to add a rule in my log4j.xml file : <category name="javax.xml.ws"> <priority value="error" /> </category> It didn't worked. So I tried the following trick: java.util.logging.Logger.getLogger("javax.xml.ws.WebServiceException").setLevel( java.util.logging.Level.OFF); it didn't worked neither. Any ideas ? It is not a big issue but it makes my catalina.log getting bigger & bigger and it's not the appropriate place for this kind of log. Chris

• iPhone SDK 3/4 App will not run on a iPhone 2.x device even with deployment target set to 2.0!

  - by MarqueIV

  Ok... I know about the difference between the base/active SDKs and the deployment target. I have my base SDK set at 4.0 and the deployment target set at 2.0. I am not using any APIs post 2.x, conditional or otherwise. Since I can't debug on a 2.x device, after building it, I use the iPhone Configuration Utility to install the app on the device, which it does just fine. Problem is, it doesn't run! I just get a blank screen. The main window never comes up! Now before you ask... I had this same problem with the iPhone SDK 3.x. I upgraded to the 4.x hoping it would be solved. It wasn't. Yes the provisioning profile is installed. (Couldn't install the app if it wasn't.) This same compiled app works fine on 3.x devices. Same with 4.x devices. Just not 2.x devices. Again, no I am not using any post-2.x SDKs. To prove this I created a brand-new, window-based app from the 'New Project' dialog and the only changes I made was the background color of the window (to prove the XIB loaded) and I set the deployment target to 2.0 (It's still compiled against the 4.x SDK though.) Again, it runs fine on 3.x or 4.x devices, but just a black, blank screen on 2.x devices. I've tried this on three separate 2.x devices included one freshly restored. I've used three separate dev machines (MacBook Pro with the 3.x SDK, MacBook Pro with the 4.x SDK and a Mac Pro with the 3.x SDK.) Same result every time. I am stumped. The fact that even an unmodified project doesn't run really has me confused. Could it be the XIB file? Did they change the format from 2.x to something newer in the 3.x SDK? If so, how do I set it back to 2.x. (Again, this is just a complete guess.) But I'm really stumped! Mark

• How to link C# and C++ assemblies into a single executable

  - by swingkid

  I have VS2008 solution containg a project that generates a C# executable that references a project that generates a dll containing both C++/CLI and unmanaged C++. I would like to merge these into a single executable, as the C++ dll contains security code that I want to embed in the main executable. I cannot use ILMerge, as the dll contains both managed and unmanaged code. The suggested solution seems to be to use link.exe to link the C# assembly with the C++ object files. This is what I am trying to do. I manually edited the project file for the c# executable to generate a netmodule. I added a post build step to the executable project to run link.exe to link the c# netmodule and the compiled C++ object files together, then run mt.exe to merge the assembly manifests created by both projects. This runs successfully, but the exe still contains a reference to and uses the c++ types defined in the dll generated by the normal build process for the C++ project. I then specified /NOASSEMBLY in the project settings for the C++ dll, so it also generates a netmodule. In the C# project, I removed the reference to the C++ project, but added a project dependancy in the solution. I manually edited the C# project file to include similar to: <ItemGroup> <AddModules Include="..\Debug\librarycode.netmodule" /> </ItemGroup> i.e. to reference the C++ netmodule that is now generated by the C++ project. However, now the linker step in my post build event fails with: error LNK2027: unresolved module reference 'librarycode.netmodule' fatal error LNK1311: 1 unresolved module references: This is entirely understandable, as I am not linking in the librarycode netmodule; I am linking in the C++ object files used to generate the netmodule instead. So in short, how do I merge a c# executable and C++ object files into a single assembly? What have I missed? My source of reference so far (appart from the link.exe command link reference etc on MSDN) are the two following articles: http://blogs.msdn.com/texblog/archive/2007/04/05/linking-native-c-into-c-applications.aspx http://www.hanselman.com/blog/MixingLanguagesInASingleAssemblyInVisualStudioSeamlesslyWithILMergeAndMSBuild.aspx I have a demonstration solution that shows my workings so far, if this helps. Thank you very much in advance.

• CCNet web dashboard not showing anything when MSBuild fails

  - by cfdev9

  I have a simple project in ccnet using svn & msbuild only. There is a 30 second trigger for svn and the msbuild file compiles a web application then copies it to a numbered build folder. When an error occurs in the msbuild task I get a failed build. When I view a failed build in the web dashboard I can see the 'Modifications since last build' section in the dashboard, but nothing else. I have to click on the build log and read through all of the xml in the error log to see what the error was. Why won't the dashboard show the errors from the build log? I haven't changed anything in the dashboard.config since installing ccnet. Dashboard Version : 1.5.7256.1 <project name="SimpleWebapp1"> <artifactDirectory>C:\Program Files\CruiseControl.NET\server\SimpleWebapp1\Artifacts\</artifactDirectory> <triggers> <intervalTrigger name="continuous" seconds="30" buildCondition="IfModificationExists" initialSeconds="5" /> </triggers> <sourcecontrol type="svn"> <executable>C:\Program Files\CollabNet\Subversion Client\svn.exe</executable> <trunkUrl>https://server:8443/svn/SimpleWebapp1/trunk</trunkUrl> <workingDirectory>D:\CCNetSandbox\SimpleWebapp1</workingDirectory> <username>username</username> <password>password</password> </sourcecontrol> <tasks> <msbuild> <executable> C:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe </executable> <workingDirectory> D:\CCNetSandbox\SimpleWebapp1 </workingDirectory> <projectFile>SimpleWebapp1.build</projectFile> <buildArgs>/p:Configuration=Debug /p:Platform="Any CPU"</buildArgs> <targets>CompileLatest</targets> <timeout>900</timeout> <logger>ThoughtWorks.CruiseControl.MsBuild.XMLLogger, C:\Program Files\CruiseControl.NET\server\ThoughtWorks.CruiseControl.MsBuild.dll</logger> </msbuild> </tasks> <publishers> <xmllogger /> <buildpublisher> <publishDir>C:\Program Files\CruiseControl.NET\server\SimpleWebapp1\Artifacts\</publishDir> <useLabelSubDirectory>true</useLabelSubDirectory> </buildpublisher> </publishers> </project>

• Storing a set of criteria in another table

  - by bendataclear

  I have a large table with sales data, useful data below: RowID Date Customer Salesperson Product_Type Manufacturer Quantity Value 1 01-06-2004 James Ian Taps Tap Ltd 200 £850 2 02-06-2004 Apple Fran Hats Hats Inc 30 £350 3 04-06-2004 James Lawrence Pencils ABC Ltd 2000 £980 ... Many rows later... ... 185352 03-09-2012 Apple Ian Washers Tap Ltd 600 £80 I need to calculate a large set of targets from table containing values different types, target table is under my control and so far is like: TargetID Year Month Salesperson Target_Type Quantity 1 2012 7 Ian 1 6000 2 2012 8 James 2 2000 3 2012 9 Ian 2 6500 At present I am working out target types using a view of the first table which has a lot of extra columns: SELECT YEAR(Date) , MONTH(Date) , Salesperson , Quantity , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType1 , CASE WHEN Manufacturer = 'Hats Inc' AND Product_Type IN ('Hats','Coats') THEN True ELSE False END AS IsType2 ... ... , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType24 , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType25 FROM SalesTable WHERE [some stuff here] This is horrible to read/debug and I hate it!! I've tried a few different ways of simplifying this but have been unable to get it to work. The closest I have come is to have a third table holding the definition of the types with the values for each field and the type number, this can be joined to the tables to give me the full values but I can't work out a way to cope with multiple values for each field. Finally the question: Is there a standard way this can be done or an easier/neater method other than one column for each type of target? I know this is a complex problem so if anything is unclear please let me know. Edit - What I need to get: At the very end of the process I need to have targets displayed with actual sales: Type Year Month Salesperson TargetQty ActualQty 2 2012 8 James 2000 2809 2 2012 9 Ian 6500 6251 Each row of the sales table could potentially satisfy 8 of the types. Some more points: I have 5 different columns that need to be defined against the targets (or set to NULL to include any value) I have between 30 and 40 different types that need to be defined, several of the columns could contain as many as 10 different values For point 2, if I am using a row for each permutation of values, 2 columns with 10 values each would give me 100 rows for each sales person for each month which is a lot but if this is the only way to define multiple values I will have to do this. Sorry if this makes no sense!

• Django custom SQL returning single row of results when query returns 2?

  - by Alvin

  I have a custom SQL call that is returning different results to the template than I get when I run the same query against the database directly, 1 row vs 2 Query - copied from Django Debug Toolbar: SELECT ((Sum(new_recruit_interviews) / Sum(opportunities_offered)) * 100) as avg_recruit, ((Sum(inspections) / Sum(presentations)) * 100) as avg_inspect, ((Sum(contracts_signed) / Sum(roof_approvals)) * 100) as avg_contracts, ((Sum(adjusters) / Sum(contracts_signed)) * 100) as avg_adjusters, ((Sum(roof_approvals) / Sum(adjusters)) *100) as roof_approval_avg, ((Sum(roof_turned_in) / Sum(adjusters)) * 100) as roof_jobs_avg, Sum(roof_turned_in) as roof_jobs_total, ((Sum(siding_approvals) / Sum(adjusters)) *100) as siding_approval_avg, ((Sum(siding_turned_in) / Sum(adjusters)) * 100) as siding_jobs_avg, Sum(siding_turned_in) as siding_jobs_total, ((Sum(gutter_approvals) / Sum(adjusters)) *100) as gutter_approval_avg, ((Sum(gutter_turned_in) / Sum(adjusters)) * 100) as gutter_jobs_avg, Sum(gutter_turned_in) as gutter_jobs_total, ((Sum(window_approvals) / Sum(adjusters)) *100) as window_approval_avg, ((Sum(window_turned_in) / Sum(adjusters)) * 100) as window_jobs_avg, Sum(window_turned_in) as window_jobs_total, (Sum(roof_turned_in) + Sum(siding_turned_in) + Sum(gutter_turned_in) + Sum(window_turned_in)) as total_jobs, (((Sum(collections_jobs_new) + Sum(collections_jobs_previous)) / (Sum(roof_turned_in) + Sum(siding_turned_in) + Sum(gutter_turned_in) + Sum(window_turned_in))) * 100) as total_collections, sales_report_salesmen.location_id as detail_id, business_unit_location.title as title FROM sales_report_salesmen Inner Join auth_user ON sales_report_salesmen.user_id = auth_user.id Inner Join business_unit_location ON sales_report_salesmen.location_id = business_unit_location.id GROUP BY location_id Results from direct query running the above query: INSERT INTO `` (`avg_recruit`, `avg_inspect`, `avg_contracts`, `avg_adjusters`, `roof_approval_avg`, `roof_jobs_avg`, `roof_jobs_total`, `siding_approval_avg`, `siding_jobs_avg`, `siding_jobs_total`, `gutter_approval_avg`, `gutter_jobs_avg`, `gutter_jobs_total`, `window_approval_avg`, `window_jobs_avg`, `window_jobs_total`, `total_jobs`, `total_collections`, `detail_id`, `title`) VALUES (95.3968, 92.8178, 106.9622, 90.2928, 103.5420, 103.5670, 4152, 100.2494, 106.8845, 4285, 120.1297, 86.2559, 3458, 92.9658, 106.1611, 4256, 16151, 4.281469, 12, 'St Paul, MN'); VALUES (90.2982, 73.3723, 97.8474, 104.5433, 97.7585, 86.1848, 1884, 109.9268, 109.3321, 2390, 81.0156, 96.4318, 2108, 91.7200, 123.8792, 2708, 9090, 4.531573, 13, 'Denver, CO'); Results from template: {'roof_jobs_total': Decimal('4152'), 'gutter_jobs_total': Decimal('3458'), 'avg_adjusters': Decimal('90.2928'), 'title': u'St Paul, MN', 'window_approval_avg': Decimal('92.9658'), 'total_collections': Decimal('4.281469'), 'gutter_approval_avg': Decimal('120.1297'), 'avg_recruit': Decimal('95.3968'), 'siding_approval_avg': Decimal('100.2494'), 'window_jobs_total': Decimal('4256'), 'detail_id': 12L, 'siding_jobs_avg': Decimal('106.8845'), 'avg_inspect': Decimal('92.8178'), 'roof_approval_avg': Decimal('103.5420'), 'roof_jobs_avg': Decimal('103.5670'), 'total_jobs': Decimal('16151'), 'window_jobs_avg': Decimal('106.1611'), 'avg_contracts': Decimal('106.9622'), 'gutter_jobs_avg': Decimal('86.2559'), 'siding_jobs_total': Decimal('4285')} Tried tweaking it a few ways and running the results through various for loops, keep getting the same result where my results are a single row through the Django template and the expected results (through console) have 2 rows The row that is coming back is the same as the first row returned through the console query so I'm thinking that it is running correctly just a matter of passing the results through... for good measure this is the code I'm using to generate the query (yes it's a bit ugly, been playing with it) def sql_grouped(table, fields, group_by=False, where=False): from django.db import connection query = 'SELECT %s FROM %s' % (fields, table) if where: query = query + ' WHERE %s' % (where) if group_by: query = query + ' GROUP BY %s' % (group_by) cursor = connection.cursor() cursor.execute(query) desc = cursor.description data = [dict(zip([col[0] for col in desc], row)) for row in cursor.fetchall()] return data[0] any feedback is greatly appreciated - been tinkering with this since I realized I could skip a few steps by generating my averages directly within the SQL rather than post-process

• MooseX::Types declaration issue, tight test case :)

  - by TJ Thompson

  So after an embarrassing amount of time debugging, I've finally stripped this issue ([http://stackoverflow.com/questions/4621589/perl-moose-typedecorator-error-how-do-i-debug][1]) down to a simple test case. I would humbly request some help understanding why it's failing :) Here is the error message I'm getting: plxc16479 $h2/tmp/tmp18.pl This method [new] requires a single argument. at /nfs/pdx/disks/nehalem.pde.077/perl/5.12.2/lib64/site_perl/MooseX/Types/TypeDecorator.pm line 91 MooseX::Types::TypeDecorator::new('MooseX::Types::TypeDecorator=HASH(0x655b90)') called at /nfs/pdx/disks/nehalem.pde.077/projects/lib/Program-Plist-Pl/lib/Program/Plist/Pl.pm line 10 Program::Plist::Pl::BUILD('Program::Plist::Pl=HASH(0x63d478)', 'HASH(0x63d220)') called at generated method (unknown origin) line 29 Program::Plist::Pl::new('Program::Plist::Pl') called at /nfs/pdx/disks/nehalem.pde.077/tmp/tmp18.pl line 10 Wrapper test script: use strict; use warnings; BEGIN {push(@INC, split(':', $ENV{PERL_TEST_LIBS}))}; use Program::Plist::Pl; my $obj = Program::Plist::Pl->new(); Program::Plist::Pl file: package Program::Plist::Pl; use Moose; use namespace::autoclean; use Program::Types qw(Pattern); # <-- Removing this fixes error use Program::Plist::Pl::Pattern; sub BUILD { my $pattern_obj = Program::Plist::Pl::Pattern->new(); } __PACKAGE__->meta->make_immutable; 1; Program::Types file: package Program::Types; use MooseX::Types -declare => [qw(Pattern)]; class_type Pattern, {class => 'Program::Plist::Pl::Pattern'}; 1; And the Program::Plist::Pl::Pattern file: package Program::Plist::Pl::Pattern; use Moose; use namespace::autoclean; __PACKAGE__->meta->make_immutable; 1; Notes: While I don't need the Pattern type from Program::Types in the above code, I do in other code that is stripped out. The PERL_TEST_LIBS env var I'm pulling INC paths from only contains paths to the project modules. There are no other modules loaded from these paths. It appears the MooseX::Types definition for Pattern is causing problems, but I'm not sure why. Documentation shows the syntax I am using, but it's possible I'm misusing class_type as there isn't much said about it. Intent is to be able to use Pattern for type checking via MooseX::Params::Validate to verify the argument is a 'Program::Plist::Pl::Program' object. I've found that removing the intervening class Program::Plist::Pl from the equation by directly calling Pattern-new from the tmp18.pl wrapper results in no error, even when the Program::Types Pattern type is imported.

  Hello, I have 2 applications that I use with Aquatic Prime. One is an application just with the Aquatic Prime framework, and the other is an application that I've been working on that has been incorporated with the Aquatic Prime framework. The first application I mentioned before has its SDK set to 10.5 with the architecture to 32-bit. The second application I made has its SDK that is set to 10.6 (which it has to since I need NSRunningApplication) and its architecture to 32-bit. Now my question is, whenever I debug my first application it works perfectly fine, but with my second it gives me this interrupted error right after Running. What's going wrong? I've tried doing some breakpoints like "objc-exception-throw" but all it says is stopped at breakpoint 1. I need 10.6 in my application, but I also need Aquatic Prime. Can anyone help me solve this problem? Ok here's the one from the stack trace which I have no idea how to read: 0x91cdff11 <+0000> push %ebp 0x91cdff12 <+0001> mov %esp,%ebp 0x91cdff14 <+0003> sub $0x28,%esp 0x91cdff17 <+0006> mov %ebx,-0xc(%ebp) 0x91cdff1a <+0009> mov %esi,-0x8(%ebp) 0x91cdff1d <+0012> mov %edi,-0x4(%ebp) 0x91cdff20 <+0015> call 0x91cdff25 <objc_exception_throw+20> 0x91cdff25 <+0020> pop %ebx 0x91cdff26 <+0021> mov 0x8(%ebp),%esi 0x91cdff29 <+0024> lea 0xe4cbb8b(%ebx),%edi 0x91cdff2f <+0030> mov 0x4(%edi),%eax 0x91cdff32 <+0033> test %eax,%eax 0x91cdff34 <+0035> jne 0x91cdff3b <objc_exception_throw+42> 0x91cdff36 <+0037> call 0x91ce4f53 <set_default_handlers> 0x91cdff3b <+0042> mov %esi,(%esp) 0x91cdff3e <+0045> nop 0x91cdff3f <+0046> nopl 0x0(%eax) 0x91cdff43 <+0050> mov %esi,(%esp) 0x91cdff46 <+0053> call *0x4(%edi) 0x91cdff49 <+0056> lea 0xfd44(%ebx),%eax 0x91cdff4f <+0062> mov %eax,(%esp) 0x91cdff52 <+0065> call 0x91ce4e1f <_objc_fatal> The the GDB tells me its all good: run [Switching to process 990] Running… 2009-10-14 15:20:33.233 ApplicationName[990:a0f] init Sincerely, Kevin

• Updating / refreshing a live geojson layer | JSON & JS Variable

  - by Ozaki

  TLDR I am trying to get my geoJSON layer to update, currently it will 1. Create the vector mark, 2. Remove the vector mark, 3. Set the JS variable for lat and lon, 4. Unset the variable??? :S Hey S O. I have a geojson layer set up as follows: //GeoJSON Layer// var layer1 = new OpenLayers.Layer.GML("My GeoJSON Layer", "coordinates", {format: OpenLayers.Format.GeoJSON, styleMap: style_red}); My features are set up as follows: var latitude = 0.0; // as 0.0 it will draw the point in. var longitude = 0.0; // as 0.0 it will draw the point in. //var longitude = getlongitude; where getlongitude = JSON string of longitude. var point = new OpenLayers.Geometry.Point(longitude, latitude); pointFeature = new OpenLayers.Feature.Vector(point, null, style_red); var style_red = OpenLayers.Util.extend({}, layer_style); style_red.strokeColor = "red"; style_red.fillColor = "black"; style_red.fillOpacity = 0.5; style_red.graphicName = "circle"; style_red.pointRadius = 3.8; style_red.strokeWidth = 2; style_red.strokeLinecap = "butt"; and my layer updating function: function UpdateLayer(){ var p = new OpenLayers.Format.GeoJSON({ 'internalProjection': new OpenLayers.Projection("EPSG:900913"), 'externalProjection': new OpenLayers.Projection("EPSG:4326") }); var url = "coordinates"; OpenLayers.loadURL(url, {}, null, function(r) { var f = p.read(r.responseText); map.layers[2].destroyFeatures(); map.layers[2].addFeatures(pointFeature); }); setTimeout("UpdateLayer()",1000) } Any idea what I am doing wrong or what I am missing? Edit1 It now removes the feature (was map.layers[1]) previously... But will not add the new feature.. Edit2 I managed to get it to redraw a point but not with live data. It should draw the point at what (latitude) & (longitude) are equal to. I am trying to set latitude & longitude to some JSON string but every time straight after it sets the variable it changes it back to "undefined" as soon as it passes the line after var latitude? (using firebug & firequery to debug)

• BindException with INTERNET permission requested

  I have seen several questions regarding SocketException when using Android, but none of them cover the BindException that I get even with the INTERNET permission specified in my manifest. Here is part of my manifest: <uses-permission android:name="android.permission.INTERNET"></uses-permission> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.READ_OWNER_DATA"></uses-permission> <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> <uses-permission android:name="android.permission.ACCOUNT_MANAGER"></uses-permission> <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS"></uses-permission> Here is the relevant portion of my LogCat output: 04-22 14:49:06.117: DEBUG/MyLibrary(4844): Address to bind: 192.168.1.14 port: 843 04-22 14:49:06.197: WARN/System.err(4844): java.net.BindException: Permission denied (maybe missing INTERNET permission) 04-22 14:49:06.207: WARN/System.err(4844): at org.apache.harmony.luni.platform.OSNetworkSystem.socketBindImpl(Native Method) 04-22 14:49:06.207: WARN/System.err(4844): at org.apache.harmony.luni.platform.OSNetworkSystem.bind(OSNetworkSystem.java:107) 04-22 14:49:06.217: WARN/System.err(4844): at org.apache.harmony.luni.net.PlainSocketImpl.bind(PlainSocketImpl.java:184) 04-22 14:49:06.217: WARN/System.err(4844): at java.net.ServerSocket.bind(ServerSocket.java:414) 04-22 14:49:06.227: WARN/System.err(4844): at org.apache.harmony.nio.internal.ServerSocketChannelImpl$ServerSocketAdapter.bind(ServerSocketChannelImpl.java:213) 04-22 14:49:06.227: WARN/System.err(4844): at java.net.ServerSocket.bind(ServerSocket.java:367) 04-22 14:49:06.237: WARN/System.err(4844): at org.apache.harmony.nio.internal.ServerSocketChannelImpl$ServerSocketAdapter.bind(ServerSocketChannelImpl.java:283) 04-22 14:49:06.237: WARN/System.err(4844): at mylibrary.net.PolicyConnection$PolicyServerWorker.(PolicyConnection.java:201) I Really hope this is a simple problem and not something complicated by the fact that the binding is occurring within a worker thread on a port less than 1024.

• I need help with this ogre dependent header (Qgears)

  I'm 2 errors away from compiling Qgears. (Hacked Version of the Final Fantasy VII Engine) I've messed with the preprocessors to load the actual location of the ogre header files.

Edit: I added the semicolon and I have one more error in the header file: error: expected unqualified-id before ‘{’ token

• ASP.NET: Large number of Session_Start with same session id

  - by Jaap

  I'm running a ASP.NET website on my development box (.NET 2.0 on Vista/IIS7). The Session_Start method in global.asax.cs logs every call to a file (log4net). The Session_End method also logs every call. I'm using InProc session state, and set the session timeout to 5 mins (to avoid waiting for 20 mins). I hit the website, wait for 5 minutes unit I see the Session_End logging. Then I F5 the website. The browsers still has the session cookie and sends it to the server. Session_Start is called and a new session is created using the same session id (btw: I need this to be the same session id, because it is used to store data in database). Result: Every time I hit F5 on a previously ended session, the Session_Start method is called. When I open a different browser, the Session_Start method is called just once. Then after 5 minutes the Session_End each F5 causes the Session_Start method to execute. Can anyone explain why this is happening? Update: After the Session timeout, all subsequent requests have a session start & session end. So in the end my question is: why are the sessions on these subsequent request closed immediatly? 2010-02-09 14:49:08,754 INFO Global.asax[7486] [(null)] - Session started.

• Custom validator not invoked when using Validation Application Block through configuration

  - by Chris

  I have set up a ruleset in my configuration file which has two validators, one of which is a built-in NotNullValidator, the other of which is a custom validator. The problem is that I see the NotNullValidator hit, but not my custom validator. The custom validator is being used to validate an Entity Framework entity object. I have used the debugger to confirm the NotNull is hit (I forced a failure condition so I saw it set an invalid result), but it never steps into the custom one. I am using MVC as the web app, so I defined the ruleset in a config file at that layer, but my custom validator is defined in another project. However, I wouldn't have thought that to be a problem because when I use the Enterprise Library Configuration tool inside Visual Studio 2008 it is able to set the type properly for the custom validator. As well, I believe the custom validator is fine as it builds ok, and the config tool can reference it properly. Does anybody have any ideas what the problem could be, or even what to do/try to debug further? Here is a stripped down version of my custom validator: [ConfigurationElementType(typeof(CustomValidatorData))] public sealed class UserAccountValidator : Validator { public UserAccountValidator(NameValueCollection attributes) : base(string.Empty, "User Account") { } protected override string DefaultMessageTemplate { get { throw new NotImplementedException(); } } protected override void DoValidate(object objectToValidate, object currentTarget, string key, ValidationResults results) { if (!currentTarget.GetType().Equals(typeof(UserAccount))) { throw new Exception(); } UserAccount userAccountToValidate = (UserAccount)currentTarget; // snipped code ... this.LogValidationResult(results, "The User Account is invalid", currentTarget, key); } } Here is the XML of my ruleset in Validation.config (the NotNull rule is only there to force a failure so I could see it getting hit, and it does): <validation> <type defaultRuleset="default" assemblyName="MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="MyProj.Entities.UserAccount"> <ruleset name="default"> <properties> <property name="HashedPassword"> <validator negated="true" messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.NotNullValidator, Microsoft.Practices.EnterpriseLibrary.Validation, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Not Null Validator" /> </property> <property name="Property"> <validator messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="MyProj.Entities.UserAccountValidator, MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Custom Validator" /> </property> </properties> </ruleset> </type> </validation> And here is the stripped down version of the way I invoke the validation: var type = entity.GetType() var validator = ValidationFactory.CreateValidator(type, "default", new FileConfigurationSource("Validation.config")) var results = validator.Validate(entity) Any advice would be much appreciated! Thanks, Chris

• Custom property editors do not work for request parameters in Spring MVC?

  Hello, I'm trying to create a multiaction web controller using Spring annotations. This controller will be responsible for adding and removing user profiles and preparing reference data for the jsp page. @Controller public class ManageProfilesController { @InitBinder public void initBinder(WebDataBinder binder) { binder.registerCustomEditor(UserAccount.class,"account", new UserAccountPropertyEditor(userManager)); binder.registerCustomEditor(Profile.class, "profile", new ProfilePropertyEditor(profileManager)); logger.info("Editors registered"); } @RequestMapping("remove") public void up( @RequestParam("account") UserAccount account, @RequestParam("profile") Profile profile) { ... } @RequestMapping("") public ModelAndView defaultView(@RequestParam("account") UserAccount account) { logger.info("Default view handling"); ModelAndView mav = new ModelAndView(); logger.info(account.getLogin()); mav.addObject("account", account); mav.addObject("profiles", profileManager.getProfiles()); mav.setViewName(view); return mav; } ... } Here is the part of my webContext.xml file: <context:component-scan base-package="ru.mirea.rea.webapp.controllers" /> <context:annotation-config/> <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <value> ... /home/users/manageProfiles=users.manageProfilesController </value> </property> </bean> <bean id="users.manageProfilesController" class="ru.mirea.rea.webapp.controllers.users.ManageProfilesController"> <property name="view" value="home\users\manageProfiles"/> </bean> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> However, when i open the mapped url, i get exception: java.lang.IllegalArgumentException: Cannot convert value of type [java.lang.String] to required type [ru.mirea.rea.model.UserAccount]: no matching editors or conversion strategy found I use spring 2.5.6 and plan to move to the Spring 3.0 in some not very distant future.

• PriorityQueue update problems

  - by Bharat

  After going through a bunch of questions here on SO, I still have no idea what exactly is going wrong with my code and would appreciate some help. I'm trying to implement a priority queue based on f-costs for an A* algorithm, and while the algorithm works fine for short pathfinding distances, it seems to go wrong when there's an obstacle or when the distance between start and goal points is greater than about 30 squares (although sometimes it screws up for less too). while(!m_qOpenList.isEmpty()) { m_xCurrent=m_qOpenList.poll(); m_xCurrent.setBackground(Color.red); m_qClosedList.add(m_xCurrent); if(m_xCurrent.getStatus()==2) { System.out.println("Target Reached"); solved=true; break; } iX=m_xCurrent.getXCo(); iY=m_xCurrent.getYCo(); for(i=iX-1;i<=iX+1;i++) for(j=iY-1;j<=iY+1;j++) { if(i<0||j<0||i>m_iMazeX||j>m_iMazeX||(i==iX&&j==iY) || m_xNode[i][j].getStatus()==4|| m_qClosedList.contains(m_xNode[i][j])) continue; m_xNode[i][j].score(m_xCurrent,m_xGoal); m_qOpenList.add(m_xNode[i][j]); } } It's quite rudimentary as I'm just trying to get it to work for now. m_qOpenList is the PriorityQueue. The problem is that when I debug the program, at some point (near an obstacle), a Node with a fcost of say 84 has higher priority than a node with an fcost of 70. I am not attempting to modify the values once they're on the priority queue. You'll notice that I add at the end of the while loop (I read somewhere that the priorityqueue reorders itself when stuff is added to it), and poll right after that at the beginning. Status of 2 means the Node is the goal, and a status of 4 means that it is unwalkable. public int compareTo(Node o) { if(m_iF<o.m_iF) return -1; if(m_iF>o.m_iF) return 1; return 0; } And that's the compareTo function. Can you see a problem? =(

• C# DirectSound - Capture buffers not continuous

  - by Wizche

  Hi, I'm trying to capture raw data from my line-in using DirectSound. My problem is that, from a buffer to another the data are just inconsistent, if for example I capture a sine I see a jump from my last buffer and the new one. To detected this I use a graph widget to draw the first 500 elements of the last buffer and the 500 elements from the new one: Snapshot I initialized my buffer this way: format = new WaveFormat { SamplesPerSecond = 44100, BitsPerSample = (short)bitpersample, Channels = (short)channels, FormatTag = WaveFormatTag.Pcm }; format.BlockAlign = (short)(format.Channels * (format.BitsPerSample / 8)); format.AverageBytesPerSecond = format.SamplesPerSecond * format.BlockAlign; _dwNotifySize = Math.Max(4096, format.AverageBytesPerSecond / 8); _dwNotifySize -= _dwNotifySize % format.BlockAlign; _dwCaptureBufferSize = NUM_BUFFERS * _dwNotifySize; // my capture buffer _dwOutputBufferSize = NUM_BUFFERS * _dwNotifySize / channels; // my output buffer I set my notifications one at half the buffer and one at the end: _resetEvent = new AutoResetEvent(false); _notify = new Notify(_dwCapBuffer); bpn1 = new BufferPositionNotify(); bpn1.Offset = ((_dwCapBuffer.Caps.BufferBytes) / 2) - 1; bpn1.EventNotifyHandle = _resetEvent.SafeWaitHandle.DangerousGetHandle(); bpn2 = new BufferPositionNotify(); bpn2.Offset = (_dwCapBuffer.Caps.BufferBytes) - 1; bpn2.EventNotifyHandle = _resetEvent.SafeWaitHandle.DangerousGetHandle(); _notify.SetNotificationPositions(new BufferPositionNotify[] { bpn1, bpn2 }); observer.updateSamplerStatus("Events listener initialization complete!\r\n"); And here is how I process the events. /* Process thread */ private void eventReceived() { int offset = 0; _dwCaptureThread = new Thread((ThreadStart)delegate { _dwCapBuffer.Start(true); while (isReady) { _resetEvent.WaitOne(); // Notification received /* Read the captured buffer */ Array read = _dwCapBuffer.Read(offset, typeof(short), LockFlag.None, _dwOutputBufferSize - 1); observer.updateTextPacket("Buffer: " + count.ToString() + " # " + read.GetValue(read.Length - 1).ToString() + " # " + read.GetValue(0).ToString() + "\r\n"); /* Print last/new part of the buffer to the debug graph */ short[] graphData = new short[1001]; Array.Copy(read, graphData, 1000); db.SetBufferDebug(graphData, 500); observer.updateGraph(db.getBufferDebug()); offset = (offset + _dwOutputBufferSize) % _dwCaptureBufferSize; /* Out buffer not used */ /*_dwDevBuffer.Write(0, read, LockFlag.EntireBuffer); _dwDevBuffer.SetCurrentPosition(0); _dwDevBuffer.Play(0, BufferPlayFlags.Default);*/ } _dwCapBuffer.Stop(); }); _dwCaptureThread.Start(); } Any advise? I'm sure I'm failing somewhere in the event processing, but I cant find where. I had developed the same application using the WaveIn API and it worked well. Thanks a lot...

• .NET: understanding web.config in asp.net

  - by mark smith

  Hi there, Does anyone know of a good link to explain how to use the web.config...... For example, i am using forms authentication... and i notice there is a system.web and then it closed /system.web and then below configuration there are additional location tags here is an example, if you ntoice there is an authentication mode=forms with authorization i presume this is the ROOT....... It is also self contained within a system.web .... Below this there are more location= with system.web tags.... I have never really understand what i am actually doing.. I have tried checkign the MSDN documentation but still i don't fully understand up.... Can anyone help? If you notice with my example.... everything is stored in 1 web.config... i thought the standard waas create a standard web.config and then create another web.config in the directory where i wish to protect it..??? <configuration> <system.web> <compilation debug="true" strict="false" explicit="true" targetFramework="4.0" /> <authentication mode="Forms"> <forms loginUrl="Login.aspx" defaultUrl="Login.aspx" cookieless="UseCookies" timeout="60"/> </authentication> <authorization> <allow users="*"/> </authorization> </system.web> <location path="Forms"> <system.web> <authorization> <deny users="?"/> <allow users="*"/> </authorization> </system.web> </location> <location path="Forms/Seguridad"> <system.web> <authorization> <allow roles="Administrador"/> <deny users="?"/> </authorization> </system.web> </location>

• Accurately display upload progress in Silverilght upload

  - by Matt

  I'm trying to debug a file upload / download issue I'm having. I've got a Silverlight file uploader, and to transmit the files I make use of the HttpWebRequest class. So I create a connection to my file upload handler on the server and begin transmitting. While a file uploads I keep track of total bytes written to the RequestStream so I can figure out a percentage. Now working at home I've got a rather slow connection, and I think Silverlight, or the browser, is lying to me. It seems that my upload progress logic is inaccurate. When I do multiple file uploads (24 images of 3-6mb big in my testing), the logic reports the files finish uploading but I believe that it only reflects the progress of written bytes to the RequestStream, not the actual amount of bytes uploaded. What is the most accurate way to measure upload progress. Here's the logic I'm using. public void Upload() { if( _TargetFile != null ) { Status = FileUploadStatus.Uploading; Abort = false; long diff = _TargetFile.Length - BytesUploaded; UriBuilder ub = new UriBuilder( App.siteUrl + "upload.ashx" ); bool complete = diff <= ChunkSize; ub.Query = string.Format( "{3}name={0}&StartByte={1}&Complete={2}", fileName, BytesUploaded, complete, string.IsNullOrEmpty( ub.Query ) ? "" : ub.Query.Remove( 0, 1 ) + "&" ); HttpWebRequest webrequest = ( HttpWebRequest ) WebRequest.Create( ub.Uri ); webrequest.Method = "POST"; webrequest.BeginGetRequestStream( WriteCallback, webrequest ); } } private void WriteCallback( IAsyncResult asynchronousResult ) { HttpWebRequest webrequest = ( HttpWebRequest ) asynchronousResult.AsyncState; // End the operation. Stream requestStream = webrequest.EndGetRequestStream( asynchronousResult ); byte[] buffer = new Byte[ 4096 ]; int bytesRead = 0; int tempTotal = 0; Stream fileStream = _TargetFile.OpenRead(); fileStream.Position = BytesUploaded; while( ( bytesRead = fileStream.Read( buffer, 0, buffer.Length ) ) != 0 && tempTotal + bytesRead < ChunkSize && !Abort ) { requestStream.Write( buffer, 0, bytesRead ); requestStream.Flush(); BytesUploaded += bytesRead; tempTotal += bytesRead; int percent = ( int ) ( ( BytesUploaded / ( double ) _TargetFile.Length ) * 100 ); UploadPercent = percent; if( UploadProgressChanged != null ) { UploadProgressChangedEventArgs args = new UploadProgressChangedEventArgs( percent, bytesRead, BytesUploaded, _TargetFile.Length, _TargetFile.Name ); SmartDispatcher.BeginInvoke( () => UploadProgressChanged( this, args ) ); } } //} // only close the stream if it came from the file, don't close resizestream so we don't have to resize it over again. fileStream.Close(); requestStream.Close(); webrequest.BeginGetResponse( ReadCallback, webrequest ); }

• Ray-Box Intersection during Scene traversal with matrix transforms

  - by Myx

  Hello: There are a few ways that I'm testing my ray-box intersections: Using the ComputeIntersectionBox(...) method, that takes a ray and a box as arguments and computes the closest intersection of the ray and the box. This method works by forming a plane with each of the faces of the box and finding an intersection with each of the planes. Once an intersection is found, a check is made whether or not the point is on the surface of the box by checking that the intersection point is between the corner points. When I look at rays after running this algorithm on two different boxes, I obtain the correct intersections. Using ComputeIntersectionScene(...) method without using the matrix transformations on a scene that has two spheres, a dodecahedron (a triangular mesh), and two boxes. ComputeIntersectionScene(...) recursively traverses all of the nodes of the scene graph and computes the closest intersection with the given ray. This test in particular does not apply any transformations that parent nodes may have that also need to be applied to their children. With this test, I also obtain the correct intersections. Using ComputeIntersectionScene(...) method WITH the matrix transformations. This test works like the one above except that before finding an intersection between the ray and a node in the scene, the ray is transformed into the node's coordinate frame using the inverse of the node's transformation matrix and after the intersection has been computed, this intersection is transformed back into the world coordinates by applying the transformation matrix to the intersection point. When testing with the third method on the same scene file as described in 2, testing with 4 rays (thus one ray intersects the one sphere, one ray the the other sphere, one ray one box, and one ray the other box), only the two spheres get intersected and the two boxes do not get intersections. When I debug looking into my ComputeIntersectionBox(...) method, it actually tells me that the ray intersects every plane on the box but each intersection point does not lie on the box. This seems to be strange behavior, since when using test 2 without transformations, I obtain the correct box intersections (thus, I believe my ray-box intersection to be correct) and when using test 3 WITH transformations, I obtain the correct sphere intersections (thus, I believe my transformed ray should be OK). Any suggestions where I could be going wrong? Thank you in advance.

• JSF Composite Component

  - by purecharger

  I'm trying to create a composite component for use in my Seam application, and I'm running into problems with the simplest "hello, world" component. I have placed a file named hello.xhtml in {jboss deploy}/application.ear/application.war/resources/greet : <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:composite="http://java.sun.com/jsf/composite"> <head> <title>My First Composite Component</title> </head> <body> <composite:interface> <composite:attribute name="who"/> </composite:interface> <composite:implementation> <h:outputText value="Hello, #{cc.attrs.who}!"/> </composite:implementation> </body> </html> Now in home.xhtml, located at the root of my webapp ({jboss deploy}/application.ear/application.war/home.xhtml): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:g="http://java.sun.com/jsf/composite/greet" xmlns:s="http://jboss.com/products/seam/taglib" template="layout/template.xhtml"> <ui:define name="content"> <div id="content"> <g:hello who="World"/> <br/> </div> </ui:define> </ui:composition> But my "hello, world" is not displayed, and I dont get any error messages, even when I turn on debug level logging for com.sun and javax.faces categories. Any ideas?

• Is Ogre's use of Exceptions a good way of using them?

  - by identitycrisisuk

  I've managed to get through my C++ game programming career so far virtually never touching exceptions but recently I've been working on a project with the Ogre engine and I'm trying to learn properly. I've found a lot of good questions and answers here on the general usage of C++ exceptions but I'd like to get some outside opinions from here on whether Ogre's usage is good and how best to work with them. To start with, quoting from Ogre's documentation of it's own Exception class: OGRE never uses return values to indicate errors. Instead, if an error occurs, an exception is thrown, and this is the object that encapsulates the detail of the problem. The application using OGRE should always ensure that the exceptions are caught, so all OGRE engine functions should occur within a try{} catch(Ogre::Exception& e) {} block. Really? Every single Ogre function could throw an exception and be wrapped in a try/catch block? At present this is handled in our usage of it by a try/catch in main that will show a message box with the exception description before exiting. This can be a bit awkward for debugging though as you don't get a stack trace, just the function that threw the error - more important is the function from our code that called the Ogre function. If it was an assert in Ogre code then it would go straight to the code in the debugger and I'd be able to find out what's going on much easier - I don't know if I'm missing something that would allow me to debug exceptions already? I'm starting to add a few more try/catch blocks in our code now, generally thinking about whether it matters if the Ogre function throws an exception. If it's something that will stop everything working then let the main try/catch handle it and exit the program. If it's not of great importance then catch it just after the function call and let the program continue. One recent example of this was building up a vector of the vertex/fragment program parameters for materials applied to an entity - if a material didn't have any parameters then it would throw an exception, which I caught and then ignored as it didn't need to add to my list of parameters. Does this seem like a reasonable way of dealing with things? Any specific advice for working with Ogre is much appreciated.

• NSCalendar: Problem getting weeks in a month...

  - by AngrySpade

  I am creating a calendar control of sorts... One thing I need to know is how many weeks are there in a Month... So NSCalendar rangeOfUnit:inUnit:forDate Seems to be exactly what I need... Except I am noticing something that seems off and I can't quite figure out why this is happening... The following code... NSCalendar *calendar = [NSCalendar currentCalendar]; NSDateComponents *dateComponents = [[NSDateComponents alloc] init]; [dateComponents setYear: 2010]; [dateComponents setDay: 1]; for (int x=1; x<=12; x++) { [dateComponents setMonth: x]; NSDate *date = [calendar dateFromComponents:dateComponents]; NSLog(@"Date: %@", date); NSRange range = [calendar rangeOfUnit: NSWeekCalendarUnit inUnit: NSMonthCalendarUnit forDate:date]; NSLog(@"%d Weeks in Month %d", range.length, [dateComponents month]); } Is returning the following debug messages... 2010-03-14 13:08:10.350 Scrap[4256:207] Date: 2010-01-01 00:00:00 -0500 2010-03-14 13:08:10.351 Scrap[4256:207] 5 Weeks in Month 1 2010-03-14 13:08:10.352 Scrap[4256:207] Date: 2010-02-01 00:00:00 -0500 2010-03-14 13:08:10.352 Scrap[4256:207] 4 Weeks in Month 2 2010-03-14 13:08:10.353 Scrap[4256:207] Date: 2010-03-01 00:00:00 -0500 2010-03-14 13:08:10.353 Scrap[4256:207] 5 Weeks in Month 3 2010-03-14 13:08:10.354 Scrap[4256:207] Date: 2010-04-01 00:00:00 -0400 2010-03-14 13:08:10.355 Scrap[4256:207] 5 Weeks in Month 4 2010-03-14 13:08:10.356 Scrap[4256:207] Date: 2010-05-01 00:00:00 -0400 2010-03-14 13:08:10.357 Scrap[4256:207] 5 Weeks in Month 5 2010-03-14 13:08:10.358 Scrap[4256:207] Date: 2010-06-01 00:00:00 -0400 2010-03-14 13:08:10.358 Scrap[4256:207] 5 Weeks in Month 6 2010-03-14 13:08:10.359 Scrap[4256:207] Date: 2010-07-01 00:00:00 -0400 2010-03-14 13:08:10.360 Scrap[4256:207] 5 Weeks in Month 7 2010-03-14 13:08:10.361 Scrap[4256:207] Date: 2010-08-01 00:00:00 -0400 2010-03-14 13:08:10.364 Scrap[4256:207] 5 Weeks in Month 8 2010-03-14 13:08:10.364 Scrap[4256:207] Date: 2010-09-01 00:00:00 -0400 2010-03-14 13:08:10.365 Scrap[4256:207] 5 Weeks in Month 9 2010-03-14 13:08:10.366 Scrap[4256:207] Date: 2010-10-01 00:00:00 -0400 2010-03-14 13:08:10.366 Scrap[4256:207] 5 Weeks in Month 10 2010-03-14 13:08:10.367 Scrap[4256:207] Date: 2010-11-01 00:00:00 -0400 2010-03-14 13:08:10.367 Scrap[4256:207] 5 Weeks in Month 11 2010-03-14 13:08:10.369 Scrap[4256:207] Date: 2010-12-01 00:00:00 -0500 2010-03-14 13:08:10.369 Scrap[4256:207] 52 Weeks in Month 12 I cant quite figure out why I get 52 weeks in month 12.

• JFace ApplicationWindow: createContents isn't working

  - by jasonh

  I'm attempting to create a window that is divided into three parts. A non-resizable header and footer and then a content area that expands to fill the remaining area in the window. To get started, I created the following class: public class MyWindow extends ApplicationWindow { Color white; Font mainFont; Font headerFont; public MyWindow() { super(null); } protected Control createContents(Composite parent) { Display currentDisplay = Display.getCurrent(); white = new Color(currentDisplay, 255, 255, 255); mainFont = new Font(currentDisplay, "Tahoma", 8, 0); headerFont = new Font(currentDisplay, "Tahoma", 16, 0); // Main layout Composites and overall FillLayout Composite container = new Composite(parent, SWT.NO_RADIO_GROUP); Composite header = new Composite(container, SWT.NO_RADIO_GROUP); Composite mainContents = new Composite(container, SWT.NO_RADIO_GROUP);; Composite footer = new Composite(container, SWT.NO_RADIO_GROUP);; FillLayout containerLayout = new FillLayout(SWT.VERTICAL); container.setLayout(containerLayout); // Header Label headerLabel = new Label(header, SWT.LEFT); headerLabel.setText("Header"); headerLabel.setFont(headerFont); // Main contents Label contentsLabel = new Label(mainContents, SWT.CENTER); contentsLabel.setText("Main Content Here"); contentsLabel.setFont(mainFont); // Footer Label footerLabel = new Label(footer, SWT.CENTER); footerLabel.setText("Footer Here"); footerLabel.setFont(mainFont); return container; } public void dispose() { cleanUp(); } @Override protected void finalize() throws Throwable { cleanUp(); super.finalize(); } private void cleanUp() { if (headerFont != null) { headerFont.dispose(); } if (mainFont != null) { mainFont.dispose(); } if (white != null) { white.dispose(); } } } And this results in an empty window when I run it like this: public static void main(String[] args) { MyWindow myWindow = new MyWindow(); myWindow.setBlockOnOpen(true); myWindow.open(); Display.getCurrent().dispose(); } What am I doing wrong that I don't see three labels the way I'm trying to display them? The createContents code is definitely being called, I can step through it in Eclipse in debug mode.
