• FileNotFoundException, altough the XML file should be deployed

  - by Bernhard V

  Hi, I've got problems starting my WAR application on a local JBoss. After two other EARs are deployed and the TomcatDeployer begins deploying the WAR, I'm getting the following error message: 2010-04-28 10:01:56,605 ERROR [org.jboss.ejb.plugins.LogInterceptor] [] [main] EJBException in method: public abstract at.sozvers.stp.zpv.ejb.lea.rwsuc.EJBLeaRegelwerkSuchenRemote at.sozvers.stp.zpv.ejb.lea.rwsuc.EJBLeaRegelwerkSuchenHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException, causedBy: javax.ejb.EJBException: org.springframework.beans.factory.access.BootstrapException: Unable to initialize group definition. Group resource name [classpath*:applicationContext.xml], factory key [contextService]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'contextService' defined in URL [jar:file:/C:/ta30/nutzb/jboss-4.2.3.GA.ZPV/server/default/deploy/deploy.last/zpv-app-web-frontend-1.0-SNAPSHOT.war/WEB-INF/lib/zpv-comp-ejb-modules-1.0-SNAPSHOT-client.jar!/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.context.support.ClassPathXmlApplicationContext]: Constructor threw exception; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [at/sozvers/stp/zpv/dao/ContextBasic.xml]; nested exception is java.io.FileNotFoundException: class path resource [at/sozvers/stp/zpv/dao/ContextBasic.xml] cannot be opened because it does not exist The sad thing is that the resource at/sozvers/stp/zpv/dao/ContextBasic.xml actually is placed in a JAR in one of my EAR files which should be deployed before the WAR. And at least I get a message that the deployment of the EAR has been successful. I also looked into the JAR with my file archiver and the ContextBasic.xml is indeed there at the right place. Is there a way for me to get sure that the JAR, not the EAR as a whole, is really deployed to the JBoss? I'm already starting to lose my head about this issue. Thank you. Bernhard

• Facebooker Causing Problems with Rails Integration Testing

  - by Eric Lubow

  I am (finally) attempting to write some integration tests for my application (because every deploy is getting scarier). Since testing is a horribly documented feature of Rails, this was the best I could get going with shoulda. class DeleteBusinessTest < ActionController::IntegrationTest context "log skydiver in and" do setup do @skydiver = Factory( :skydiver ) @skydiver_session = SkydiverSession.create(@skydiver) @biz = Factory( :business, :ownership = Factory(:ownership, :skydiver = @skydiver )) end context "delete business" do setup do @skydiver_session = SkydiverSession.find post '/businesses/destroy', :id = @biz.id end should_redirect_to('businesses_path()'){businesses_path()} end end end In theory, this test seems like it should pass. My factories seem like they are pushing the right data in: Factory.define :skydiver do |s| s.sequence(:login) { |n| "test#{n}" } s.sequence(:email) { |n| "test#{n}@example.com" } s.crypted_password '1805986f044ced38691118acfb26a6d6d49be0d0' s.password 'secret' s.password_confirmation { |u| u.password } s.salt 'aowgeUne1R4-F6FFC1ad' s.firstname 'Test' s.lastname 'Salt' s.nickname 'Mr. Password Testy' s.facebook_user_id '507743444' end The problem I am getting seems to be from Facebooker only seems to happen on login attempts. When the test runs, I am getting the error: The error occurred while evaluating nil.set_facebook_session. I believe that error is to be expected in a certain sense since I am not using Facebook here for this session. Can anyone provide any insight as to how to either get around this or at least help me out with what is going wrong?

• Is it possible to make a non-nullable column nullable when used in a view? (sql server)

  - by Matt

  Hi, To start off I have two tables, PersonNames and PersonNameVariations. When a name is searched, it finds the closest name to one of the ones available in PersonNames and records it in the PersonNameVariations table if it's not already in there. I am using a stored proc to search the PersonNames for a passed in PersonNameVariationand return the information on both the PersonName found and the PersonNameVariation that was compared to it. Since I am using the Entity Framework, I needed return a complex type in the Import Function but for some reason it says my current framework doesn't support it. My last option was to use an Entity to return in my stored proc instead. The result that I needed back is the information on both the PersonName that was found and the PersonNameVariation that was recorded. Since I cannot return both entities, I created a view PersonSearchVariationInfo and added it into my Entity Framework in order to use it as the entity to return. The problem is that the search will not always return a Person Name match. It needs to be able to return only the PersonNameVariation data in some cases, meaning that all the fields in the PersonSearchVariationInfo pertaining to PersonName need to be nullable. How can I take my view and make some of the fields nullable? When I do it directly in the Entity Framework I get a mapping error: Error 4 Error 3031: Problem in mapping fragments starting at line 1202:Non-nullable column myproject_vw_PersonSearchVariationInfo.DateAdded in table myproject_vw_PersonSearchVariationInfo is mapped to a nullable entity property. C:\Users\Administrator\Documents\Visual Studio 2010\Projects\MyProject\MyProject.Domain\EntityFramework\MyProjectDBEntities.edmx 1203 15 MyProject.Domain Anyone have any ideas? Thanks, Matt

• HttpUtility does not exist in the current context

  - by Shaihi

  I get this error when compiling a C# application. Looks like a trivial error, but I can't get around it. My setup is Windows 7 64 bit. Visual-Studio 2010 C# express B2Rel. I added a reference to System.Web.dll located at C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0, but it has a yellow exclamation symbol and I still get the above error. I also have the using System.Web declaration. What am I doing wrong? Update: After getting the prompt answer pointing me at the root cause, I searched a bit in Google to where it states that System.Web.dll is for the full framework. I did not find such a reference. For newbies like me, this blog summarizes the difference between the frameworks (client and full) nicely. I could not find a spot that says whether a certain Dll is supported in the client framework or not. I guess the exclamation mark in Visual Studio should be the first signal...

• appstats broken filename in callstack

  - by Ray Yun

  When I visit appstats page and expand callstack, the file path has <path[N]> prefix. So click the file link then emit no such file or directory error. Stack: /google/appengine/datastore/datastore_rpc.py:951 make_rpc_call() /google/appengine/datastore/datastore_query.py:993 _make_query_result_rpc_call() /google/appengine/datastore/datastore_query.py:714 run_async() /google/appengine/datastore/datastore_query.py:685 run() /google/appengine/api/datastore.py:1281 GetBatcher() /google/appengine/api/datastore.py:1351 Get() /google/appengine/ext/db/init.py:1831 fetch() /google/appengine/ext/db/init.py:1778 get() /apps/fbapp/fbutil.py:232 oauth_load_fb_user() /apps/fbapp/fbutil.py:84 require_account() the error message for appengine source: [Errno 2] No such file or directory: u'/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/ipaddr/google/appengine/datastore/datastore_rpc.py' the error message for my source: IOError [Errno 2] No such file or directory: u'/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/antlr3/apps/fbapp/fbutil.py' I guess this was path problem and found some official comment from google. If your request handlers modify sys.path, you must make the same modifications to sys.path in appengine_config.py so the Appstats web interface can see all files. Actually I'm using appengine_django and two path was inserted to sys.path. I did it same again at appengine_django.py but also failed. Maybe some custom setting with appengine_config.py can solve this problem but doesn't figure out how to fix it. What can I do?

• PHP session_write_close() causes empty response

  - by Xeoncross

  When using session_write_close() in a shutdown function at the end of my script - PHP just dies. There is no error logged, response headers (firebug), or data (even whitespace!) returned. I have full PHP error reporting on with STRICT enabled and PHP 5.2.1. My guess is that since session_write_close() is being called after shutdown - some fatal error is being encountered that crashes PHP before it has a chance to send the output or log anything. This only happens on the logout page where I first: ... //If there is no session to delete (not started) if ( ! session_id()) { return; } // Get the session name $name = session_name(); // Delete the session cookie (if exists) if ( ! empty($_COOKIE[$name])) { //Get the current cookie config $params = session_get_cookie_params(); // Delete the cookie from globals unset($_COOKIE[$name], $_SESSION); //Delete the cookie on the user_agent setcookie($name, '', time()-43200, $params['path'], $params['domain'], $params['secure']); } // Destroy the session session_destroy(); ... then 2) do some more stuff 3) issue a redirect and 4) finally, after the whole page is done the register_shutdown_function(); I placed earlier runs and calls session_write_close() which saves the session to the database. The end. Since this blank response only occurs on logout I'm guessing that I'm not restarting the session properly which is causing session_write_close() to die fatally at the end of the script.

• How to catch an expected (and intended) 302 response code with generic XmlHttpRequest?

  - by Anthony

  So, if you look back at my previous question about Exchange Autodiscover, you'll see that the easiet way to get the autodiscover URL is to send a non-secure, non-authenticated GET request to the server, ala: http://autodiscover.exchangeserver.org/autodiscover/autodiscover.xml The server will respond with a 302 redirect with the correct url in the Location header. I'm trying out something really simple at first with a Chrome extension, where I have: if (req.readyState==4 && req.status==302) { return req.getResponseHeader("Location"); } With another ajax call set up with the full XML Post and the user credentials, But instead Chrome hangs at this point, and a look at the developer panel shows that it is not returning back the response but instead is acting like no response was given, meanwhile showing a Uncaught Error: NETWORK_ERR: XMLHttpRequest Exception 101 in the error log. The way I see it, refering to the exact response status is about the same as "catching" it, but I'm not sure if the problem is with Chrome/WebKit or if this is how XHR requests always handle redirects. I'm not sure how to catch this so that I can get still get the headers from the response. Or would it be possible to set up a secondary XHR such that when it gets the 302, it sends a totally different request? Quick Update I just changed it so that it doesn't check the response code: if (req.readyState==4) { return req.getResponseHeader("Location"); } and instead when I alert out the value it's null. and there is still the same error and no response in the dev console. SO it seems like it either doesn't track 302 responses as responses, or something happens after that wipes that response out?

• iPhone - openAL stops playing if I record with AVAudioRecorder

  - by Oscar Peli

  Hi there, this is an iPhone-related question: I use openAL to play some sound (I have to manage gain, pitch, etc.). I want to record what I'm playing and I use AVAudioRecorder but when I "prepareToRecord" openAL stops to play audio. What's the problem? Here is the record IBAction I use: - (IBAction) record: (id) sender { NSError *error; NSMutableDictionary *settings = [NSMutableDictionary dictionary]; [settings setValue: [NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey]; [settings setValue: [NSNumber numberWithFloat:8000.0] forKey:AVSampleRateKey]; [settings setValue: [NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey]; [settings setValue: [NSNumber numberWithInt:16] forKey:AVLinearPCMBitDepthKey]; [settings setValue: [NSNumber numberWithBool:NO] forKey:AVLinearPCMIsBigEndianKey]; [settings setValue: [NSNumber numberWithBool:NO] forKey:AVLinearPCMIsFloatKey]; NSURL *url = [NSURL fileURLWithPath:FILEPATH]; self.recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error]; self.recorder.delegate = self; self.recorder.meteringEnabled = YES; [self.recorder prepareToRecord]; [self.recorder record]; } Thanks

• aapt not found when building new Android app in NetBeans

• Reading audio with Extended Audio File Services (ExtAudioFileRead)

  - by Paperflyer

  I am working on understanding Core Audio, or rather: Extended Audio File Services Here, I want to use ExtAudioFileRead() to read some audio data from a file. This works fine as long as I use one single huge buffer to store my audio data (that is, one AudioBuffer). As soon as I use more than one AudioBuffer, ExtAudioFileRead() returns the error code -50 ("error in parameter list"). As far as I can figure out, this means that one of the arguments of ExtAudioFileRead() is wrong. Probably the audioBufferList. I can not use one huge buffer because then, dataByteSize would overflow its UInt32-integer range with huge files. Here is the code to create the audioBufferList: AudioBufferList *audioBufferList; audioBufferList = malloc(sizeof(AudioBufferList) + (numBuffers-1)*sizeof(AudioBuffer)); audioBufferList->mNumberBuffers = numBuffers; for (int bufferIdx = 0; bufferIdx<numBuffers; bufferIdx++ ) { audioBufferList->mBuffers[bufferIdx].mNumberChannels = numChannels; audioBufferList->mBuffers[bufferIdx].mDataByteSize = dataByteSize; audioBufferList->mBuffers[bufferIdx].mData = malloc(dataByteSize); } UInt32 numFrames = fileLengthInFrames; error = ExtAudioFileRead(extAudioFileRef, &numFrames, audioBufferList); Do you know what I am doing wrong here?

• Friend Assemblies in C#

  - by Tim Long

  I'm trying to create some 'friend assemblies' using the [InternalsVisibleTo()] attribute, but I can't seem to get it working. I've followed Microsoft's instructions for creating signed friend assemblies and I can't see where I'm going wrong. So I'll detail my steps here and hopefully someone can spot my deliberate mistake...? Create a strong name key and extract the public key, thus: sn -k StrongNameKey sn -p public.pk sn -tp public.pk Add the strong name key to each project and enable signing. Create a project called Internals and a class with an internal property: namespace Internals { internal class ClassWithInternals { internal string Message { get; set; } public ClassWithInternals(string m) { Message = m; } } } Create another project called TestInternalsVisibleTo: namespace TestInternalsVisibleTo { static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { var c = new Internals.ClassWithInternals("Test"); Console.WriteLine(c.Message); } } } Edit the AssemblyInfo.cs file for the Internals project, and add teh necessary attribute: [assembly: AssemblyTitle("AssemblyWithInternals")] [assembly: AssemblyDescription("")] [assembly: AssemblyConfiguration("")] [assembly: AssemblyCompany("Microsoft")] [assembly: AssemblyProduct("Internals")] [assembly: AssemblyCopyright("Copyright © Microsoft 2010")] [assembly: AssemblyTrademark("")] [assembly: AssemblyCulture("")] [assembly: ComVisible(false)] [assembly: Guid("41c590dc-f555-48bc-8a94-10c0e7adfd9b")] [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: InternalsVisibleTo("TestInternalsVisibleTo PublicKey=002400000480000094000000060200000024000052534131000400000100010087953126637ab27cb375fa917c35b23502c2994bb860cc2582d39912b73740d6b56912c169e4a702bedb471a859a33acbc8b79e1f103667e5075ad17dffda58988ceaf764613bd56fc8f909f43a1b177172bc4143c96cf987274873626abb650550977dcad1bb9bfa255056bb8d0a2ec5d35d6f8cb0a6065ec0639550c2334b9")] And finally... build! I get the following errors: error CS0122: 'Internals.ClassWithInternals' is inaccessible due to its protection level error CS1729: 'Internals.ClassWithInternals' does not contain a constructor that takes 1 arguments error CS1061: 'Internals.ClassWithInternals' does not contain a definition for 'Message' and no extension method 'Message' accepting a first argument of type 'Internals.ClassWithInternals' could be found (are you missing a using directive or an assembly reference?) Basically, it's as if I had not used the InternalsVisibleTo attrbute. Now, I'm not going to fall into the trap of blaming the tools, so what's up here? Anyone?

• linking to boost regex in gcc

  - by rboorgapally

  i am trying to compile my program which uses regex on linux. I built the boost library in the libs/regex/build by typing make -fgcc.mak which created a directory gcc which contains the following four files boost_regex-gcc-1_35 boost_regex-gcc-d-1_35 libboost_regex-gcc-1_35.a libboost_regex-gcc-d-1_35.a Now I want to use regex from my program which is in some arbitrary directory. I #included boost/regex.hpp I got the error which stated that regex.hpp is not found. Then I gave the -I option in the g++ compiler. I didn't get that error. But I get the following error undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)' I googled and found that I need to somehow link one of the above 4 libraries to my program. How can I do it. Which one should I link and why?

• Debugging a working program on Mathematica 5 with Mathematica 7

  - by Neuschwanstein

  Hi everybody, I'm currently reading the Mathematica Guidebooks for Programming and I was trying to work out one of the very first program of the book. Basically, when I run the following program: Plot3D[{Re[Exp[1/(x + I y)]]}, {x, -0.02, 0.022}, {y, -0.04, 0.042}, PlotRange -> {-1, 8}, PlotPoints -> 120, Mesh -> False, ColorFunction -> Function[{x1, x2, x3}, Hue[Arg[Exp[1/(x1 + I x2)]]]]] either I get a 1/0 error and e^\infinity error or, if I lower the PlotPoints options to, say, 60, an overflow error. I have a working output though, but it's not what it's supposed to be. The hue seems to be diffusing off the left corner whereas it should be diffusing of the origin (as can be seen on the original output) Here is the original program which apparently runs on Mathematica 5 (Trott, Mathematica Guidebook for Programming): Off[Plot3D::gval]; Plot3D[{Re[Exp[1/(x + I y)]], Hue[Arg[Exp[1/(x + I y)]]]}, {x, -0.02, 0.022}, {y, -0.04, 0.042}, PlotRange -> {-1, 8}, PlotPoints -> 120, Mesh -> False] Off[Plot3D::gval]; However, ColorFunction used this way (first Plot3D argument) doesn't work and so I tried to simply adapt to its new way of using it. Well, thanks I guess!

  My matrix multiplication code is int matMul(int ld, double** matrix) { //local variables initialize omp_set_num_threads(nthreads); #pragma omp parallel private(tid,diag,ld) shared(i,j,k,matrix) { /* Obtain and print thread id */ tid = omp_get_thread_num(); for ( k=0; k<ld; k++) { if (matrix[k][k] == 0.0) { error = 1; return error; } diag = 1.0 / matrix[k][k]; #pragma omp for for ( i=k+1; i < ld; i++) { matrix[i][k] = diag * matrix[i][k]; } for ( j=k+1; j<ld; j++) { for ( i=k+1; i<ld; i++) { matrix[i][j] = matrix[i][j] - matrix[i][k] * matrix[k][j]; } } } } return error; } I assume that it is because of matrix object only but why will it be null even though it is passed as a parameter..

• Unable to fetch initial output of "defrag" commad in Windows Server 2008 R2 in WOW64 environment.

  - by Ganesh

  Hi All, [Application & code back ground] I have an MFC application which is executing on Windows Server 2008 R2 in WOW64 environment. In which on user input it defragments the selected drive on the disk. I initiated the process(.i.e. cmd /c defrag –v c:) of defragmentation using the CreateProcess() API, along with this to display output of the process on the main screen I created the pipe using CreatePipe() API. I used PeekNamedPipe() & ReadFile() API to get the output and display. [Problem Area] When the process is launched I am not getting the initial output as below: Microsoft Disk fragmenter Copyright © 2007 Microsoft Crop. Invoking defragmentation on (C:)…. I constantly monitor the output of the process while it is under progress but not able to get any thing as output in the pipe. It seem the process is not doing any thing and appears as if the application is not responding. But after certain period of time, once the process is about to completed I get result along with the initial data. [Sample code] //Pipe created if(0 == ::CreatePipe(&l_hStdOutRead, &l_hStdOutWrite, &l_SecurityAttribute, (DWORD)NULL)) { //Error code } //Process created/launched if (0 == ::CreateProcess(NULL, (LPTSTR)f_csProcessName, &l_stSecurityAttributes, NULL, TRUE, CREATE_NO_WINDOW, NULL,NULL, &l_StartupInfo, &l_CmdPI)) { //Error code } //Read output if (0 == ::PeekNamedPipe(m_hStdOutRead, l_cArrPeekBuffer, (DWORD)NULL, (LPDWORD)NULL, &l_dwAvailable, (LPDWORD)NULL)) { //Return to read again } if (MPLUSFALSE == ::ReadFile(m_hStdOutRead, l_cArrOutput, min(BUFFER_SIZE - 2, l_dwAvailable), &l_dwRead, NULL) || !l_dwRead) { //error code } //Display data. If any one is aware of similar problem or worked on the similar issue please let me know the solution. Thanks in Advance, Ganesh

• ASP.NET MVC 2 with NServiceBus unable to load requested types

  - by dp

  I am trying to use NServiceBus with an ASP.NET MVC 2 website (using VS 2010 and the .NET 4.0 framework). However, when I run the site on my local machine, I get the following error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. Here are the relevant steps I have taken: Downloaded the NServiceBus.2.0.0.1145 binaries In my asp.net mvc app, I've added references to NServiceBus.dll and NServiceBus.Core.dll In Global.asax.cs I've added: public static IBus Bus { get; private set; } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); Bus = NServiceBus.Configure .WithWeb() .Log4Net() .DefaultBuilder() .XmlSerializer() .MsmqTransport() .IsTransactional(false) .PurgeOnStartup(false) .UnicastBus() .ImpersonateSender(false) .CreateBus() .Start(); } In web.config, I've added: <MsmqTransportConfig InputQueue="MyWebClient" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5"/> <UnicastBusConfig> <MessageEndpointMappings> <add Messages="Messages" Endpoint="MyServerInputQueue"/> </MessageEndpointMappings> </UnicastBusConfig> The error indicates that the problem is with the first line in the Global.asax.cs file. Is it possible that there is a problem with NServiceBus running under .NET 4.0?

• BN_hex2bn magicaly segfaults in openSSL

  - by xunil154

  Greetings, this is my first post on stackoverflow, and i'm sorry if its a bit long. I'm trying to build a handshake protocol for my own project and am having issues with the server converting the clients RSA's public key to a Bignum. It works in my clent code, but the server segfaults when attempting to convert the hex value of the clients public RSA to a bignum. I have already checked that there is no garbidge before or after the RSA data, and have looked online, but i'm stuck. header segment: typedef struct KEYS { RSA *serv; char* serv_pub; int pub_size; RSA *clnt; } KEYS; KEYS keys; Initializing function: // Generates and validates the servers key /* code for generating server RSA left out, it's working */ //Set client exponent keys.clnt = 0; keys.clnt = RSA_new(); BN_dec2bn(&keys.clnt->e, RSA_E_S); // RSA_E_S contains the public exponent Problem code (in Network::server_handshake): // *Recieved an encrypted message from the network and decrypt into 'buffer' (1024 byte long)* cout << "Assigning clients RSA" << endl; // I have verified that 'buffer' contains the proper key if (BN_hex2bn(&keys.clnt->n, buffer) < 0) { Error("ERROR reading server RSA"); } cout << "clients RSA has been assigned" << endl; The program segfaults at BN_hex2bn(&keys.clnt->n, buffer) with the error (valgrind output) Invalid read of size 8 at 0x50DBF9F: BN_hex2bn (in /usr/lib/libcrypto.so.0.9.8) by 0x40F23E: Network::server_handshake() (Network.cpp:177) by 0x40EF42: Network::startNet() (Network.cpp:126) by 0x403C38: main (server.cpp:51) Address 0x20 is not stack'd, malloc'd or (recently) free'd Process terminating with default action of signal 11 (SIGSEGV) Access not within mapped region at address 0x20 at 0x50DBF9F: BN_hex2bn (in /usr/lib/libcrypto.so.0.9.8) And I don't know why it is, Im using the exact same code in the client program, and it works just fine. Any input is greatly appriciated!

• OCUnit & NSBundle

  - by kpower

  I created OCUnit test in concordance with "iPhone Development Guide". Here is the class I want to test: // myClass.h #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> @interface myClass : NSObject { UIImage *image; } @property (readonly) UIImage *image; - (id)initWithIndex:(NSUInteger)aIndex; @end // myClass.m #import "myClass.m" @implementation myClass @synthesize image; - (id)init { return [self initWithIndex:0]; } - (id)initWithIndex:(NSUInteger)aIndex { if ((self = [super init])) { NSString *name = [[NSString alloc] initWithFormat:@"image_%i", aIndex]; NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"png"]; image = [[UIImage alloc] initWithContentsOfFile:path]; if (nil == image) { @throw [NSException exceptionWithName:@"imageNotFound" reason:[NSString stringWithFormat:@"Image (%@) with path \"%@\" for current index (%i) wasn't found.", [name autorelease], path, aIndex] userInfo:nil]; } [path release]; } return self; } - (void)dealloc { [image release]; [super dealloc]; } @end And my unit-test (LogicTests target): // myLogic.m #import <SenTestingKit/SenTestingKit.h> #import <UIKit/UIKit.h> #import "myClass.h" @interface myLogic : SenTestCase { } - (void)testTemp; @end @implementation myLogic - (void)testTemp { STAssertNoThrow([[myClass alloc] initWithIndex:0], "myClass initialization error"); } @end All necessary frameworks, "myClass.m" and images added to target. But on build I have an error: [[myClass alloc] initWithIndex:0] raised Image (image_0) with path \"(null)\" for current index (0) wasn't found.. myClass initialization error This code (initialization) works fine in application itself (main target) and later displays correct image. I've also checked my project folder (build/Debug-iphonesimulator/LogicTests.octest/) - there are LogicTests, Info.plist and necessary image files (image_0.png is one of them). What's wrong?

• how to show a large jpg image to the right in jqGrid's edit form ?

  - by cLee

  Is it possible to show a large (i.e. bigger than a thumbnail) jpeg image in the right-hand side of jqGrid's edit form ? Users want to look at a photo while entering data into fields ... they are describing things in the photo. I'm sure all things are possible with jQuery, but I don't know where to begin. thanks ... html: function afterSubmit(r, data, action) { // if session timeout returned: if (r.responseText == "logout") { window.location = '../scripts/logout.php'; } // if an error message is returned: if (r.responseText != "") { $('#submit_errors').html('Alert:'+r.responseText+''); // show div with error message $('#submit_errors').slideDown(); // hide error div after 10 seconds window.setTimeout(function() { $('#submit_errors').slideUp(); }, 10000); return false; // don't remove this! } return true; // don't remove this! } var lastsel; jQuery(document).ready(function(){ var mygrid = jQuery("#mobile_incidents").jqGrid({ url:'list.php?q=e', editurl:'edit.php', datatype: "json", // note: all column names are required even though some columns are hidden colNames:['Rec#','Date','Line','Photo'], colModel:[{ name:'id', index:'id', editable:true, editoptions: {readonly:'readonly'} }, { name:'mobile_discoveryDate', index:'mobile_discoveryDate', sortable:false, editable:true, edittype:'text', formatter:'date', formatoptions:{ srcformat:'Y/m/d', newformat:'m/d/Y' }, editoptions:{ size:12, maxlength:10, dataInit: function(element) { $(element).blur(); $(element).datepicker({dateFormat:'mm/dd/yyyy'}) } } }, { name:'mobile_lineName', index:'mobile_lineName', editable:true, sortable:false}, { name:'mobile_photo_name', index:'mobile_photo_name', editable:false, sortable:false} ], pager: '#mobile_incidents_pager', altRows: false, rowNum:10, rowList:[10,20], imgpath: '../include/images/jqgrid', viewrecords: true, emptyrecords:'No submissions found!', height: 260, sortname: 'id', sortorder: 'desc', gridview: true, scrollrows: true, autowidth: true, rownumbers: false, multiselect: false, subGrid:false, caption: '' }) .navGrid('#mobile_incidents_pager', // params: {add:false, edit:true, del:false, search:false, view:false, refresh:true, alertcap:' to edit:', alerttext:' . . . click on a row to highlight' }, // edit params: {top:50, left:5, editCaption: 'Edit Submission', bSubmit: 'Approve/Save', closeAfterEdit:true, afterSubmit:function(r,data){return afterSubmit(r,data,'edit');} }, {}, // add params {}, // delete params // search params: {multipleSearch: false}, // view params: {top: 150, left: 5, caption: 'View Mobile Rail Submission'} ); });

• Salesforce/PHP - outbound messages (SOAP) - memory limit issue

  - by Phill Pafford

  I'm using Salesforce to send outbound messages (via SOAP) to another server. The server can process about 8 messages at a time, but will not send back the ACK file if the SOAP request contains more than 8 messages. SF can send up to 100 outbound messages in 1 SOAP request and I think this is causing a memory issue with PHP. If I process the outbound messages 1 by 1 they all go through fine, I can even do 8 at a time with no issues. But larger sets are not working. ERROR in SF: org.xml.sax.SAXParseException: Premature end of file Looking in the HTTP error logs I see that the incoming SOAP message looks to be getting cut of which throws a PHP warning stating: Premature end of data in tag ... PHP Fatal error: Call to a member function getAttribute() on a non-object This leads me to believe that PHP is having a memory issue and can not parse the incoming message due to it's size. I was thinking I could just set: ini_set('memory_limit', '64M'); But would this be the correct approach? Is there a way I could set this to increase with the incoming SOAP request dynamically? UPDATE: Adding some code $data = fopen('php://input','rb'); $headers = getallheaders(); $content_length = $headers['Content-Length']; $buffer_length = 1000; $fread_length = $content_length + $buffer_length; $content = fread($data,$fread_length); /** * Parse values from soap string into DOM XML */ $dom = new DOMDocument(); $dom->loadXML($content); ....

• FxCop hates my usage of MVVM

  - by Dave

  I've just started to work with FxCop to see how poorly my code does against its full set of rules. I'm starting off with the "Breaking" rules, and the first one I came across was CA2227, which basically says that you should make a collection property's setter readonly, so that you can't accidentally change the collection data. Since I'm using MVVM, I've found it very convenient to use an ObservableCollection with get/set properties because it makes my GUI updates easy and concise in the code-behind. However, I can also see what FxCop is complaining about. Another situation that I just ran into is with WF, where I need to set the parameters when creating the workflow, and I'd hate to have to write a wrapper class around the collection I'm using just to avoid this particular error message. For example, here's a sample runtime error message that I get when I make properties readonly: The activity 'MyWorkflow' has no public writable property named 'MyCollectionOfStuff' What are you opinions on this? I could either ignore this particular error, but that's probably not good because I could conceivably violate this rule elsewhere in the code where MVVM doesn't apply (model only code, for example). I think I could also change it from a property to a class with methods to manipulate the underlying collection, and then raise the necessary notification from the setter method. I'm a little confused... can anyone shed some light on this?

• Creating custom IP-STS for sharepoint foundation 2010 without ADFS

  - by user252229

  I plan to create very simple custom IP-STS for SharePoint foundation 2010 without ADFS server so anyone can integrate Windows Live ID to SharePoint foundation 2010 simply without ADFS, I can't use ADFS server because it could not install on Windows Web Server 2008 (Web Edition), also I found many article use LDAP provider but it does not exists in SharePoint Foundation too (it requires Sharepoint Server Edition). After too much searching I just found the following article and find all technique except one problem. 1) Creating Custom Claim Provider: blogs.technet.com/b/speschka/archive/2010/03/13/writing-a-custom-claims-provider-for-sharepoint-2010-part-1.aspx 2) Creating Custom STS Provider: http://blogs.msdn.com/b/chunliu/archive/2010/04/02/how-to-make-use-of-a-custom-ip-sts-with-sharepoint-2010-part-1.aspx Only one step remains: I got following error after enter username in STS site and redirect to localhost/_trust/default.aspx , ( I leave EncryptingCertificateName empty). Operation is not valid due to the current state of the object I expect to get access denied error instead of that error. 1.Is it possible anyway? 2.Can anyone help me where can I find working article to create custom IP-STS without ADFS server Any idea will help me Thanks
