• The Definitive C++ Book Guide and List

  - by grepsedawk

  After more than a few questions about deciding on C++ books I thought we could make a better community wiki version. Providing QUALITY books and an approximate skill level. Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate quality, headings, etc. Note: There is a similar post for C: The Definitive C Book Guide and List Reference Style - All Levels The C++ Programming Language - Bjarne Stroustrup C++ Standard Library Tutorial and Reference - Nicolai Josuttis Beginner Introductory: C++ Primer - Stanley Lippman / Josée Lajoie / Barbara E.

• Missing styles. Is the correct theme chosen for this layout?

  - by user1820007

  Missing styles. Is the correct theme chosen for this layout? Use the Theme combo box above the layout to choose a different layout, or fix the theme style references. Failed to find style 'mapViewStyle' in current theme. I tried every solutions available to solve this problem. But nothing seems to work. I have included library in the manifest file. I even created style is styles.xml. I have chosen Google Apis build target as well. Can somebody please give me a solution. Thank you in advance for your valuable time... here is my xml file: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" style="@style/AppTheme" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.google.android.maps.MapView android:id="@+id/themap" style="@style/mapViewStyle" android:layout_width="fill_parent" android:layout_height="fill_parent" android:apiKey="here i have my key" android:clickable="true" android:enabled="true" /> </RelativeLayout> ` Here is my manifest snippet: <uses-library android:name="com.google.android.maps" /> <activity android:name=".MainActivity" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".Second" /> <acttiviy android:name=".Third" android:theme="@android:style/Theme.Black" /> </application> here is my style.xml file <style name="mapViewStyle" parent="@android:style/Theme.Black"> </style> </resources>

• How to get jQuery EasyUI datagrid and treegrid to load in background?

  - by f1r3br4nd

  I am trying build a jQuery EasyUI datagrid or treegrid out of a large query. Apparently the database takes long enough to respond that I get the "a script on this page may be busy" popup. Moreover, the entire browser (Firefox) locks up while it's waiting. I thought the whole point of AJAX was to load stuff unobtrusively. I've looked through the tutorials and documentation for EasyUI but it's not clear to me how to force a datagrid to load in the background. There are some similar unanswered questions asked on the EasyUI forums. Do I need to override the loader property of datagrid? If so, does anybody know where I can get a non-obfuscated version of the default loader function so I can be sure I understand what it's supposed to do before I write my own? Also, if I need asynchronous datagrids and datatrees with sorting and filtering features, is jQuery EasyUI the wrong library for doing this simply and cleanly? Is there some alternative jQuery library people would recommend? Thank you.

• com.jcraft.jsch.JSchException: Auth cancel

  - by Dan Fabulich

  I'm trying to write an Ant script to retrieve an URL via port tunnelling. It works great when I use a password (the names xxxx'd out for privacy): <project default="main"> <target name="main"> <sshsession host="xxxx" username="xxxx" password="xxxx"> <LocalTunnel lport="1080" rhost="xxxx" rport="80"/> <sequential> <get src="http://localhost:1080/xxxx" dest="/tmp/xxxx"/> </sequential> </sshsession> </target> </project> But it doesn't work when I use a keyfile, like this: <sshsession host="xxxx" username="xxxx" keyfile="/Users/xxxx/.ssh/id_dsa" passphrase="xxxx"> <LocalTunnel lport="1080" rhost="xxxx" rport="80"/> <sequential> <get src="http://localhost:1080/xxxx" dest="/tmp/xxxx"/> </sequential> </sshsession> I get this exception: /tmp/build.xml:8: com.jcraft.jsch.JSchException: Auth cancel at com.jcraft.jsch.Session.connect(Session.java:451) at com.jcraft.jsch.Session.connect(Session.java:150) at org.apache.tools.ant.taskdefs.optional.ssh.SSHBase.openSession(SSHBase.java:223) I'm sure I'm using the correct keyfile (I've tried using the wrong name, which gives a legitimate FileNotFoundException). I can successfully ssh from the command line without being prompted for a password. I'm sure I'm using the correct passphrase for the keyfile. What's the cause of this error and what can I do about it?

• How to use QSerialDevice in Qt?

  - by Tobias

  Hello, I am trying to use QSerialDevice in Qt to get a connection to my serial port. I also tried QextSerialPort before (which works on Windows Vista but unfortunately not on Windows XP ..) but I need an API which supports XP, Vista and Win7... I build the library and configured it this way: CONFIG += dll CONFIG += debug I did use the current version from SVN (0.2.0 - 2010-04-05) and the 0.2.0 zip package. After building the library I did copy it to my Qt Libdir (C:\Qt\2009.05\qt\lib) and also to C:\Windows\system32. Now I try to link against the lib in my project file: LIBS += -lqserialdevice I import the needed header (abstractserial.h) and use my own AbstractSerial like this: // Initialize this->serialPort->setDeviceName("COM1"); if (!this->serialPort->open(QIODevice::ReadWrite | QIODevice::Unbuffered)) qWarning() << "Error" << this->serialPort->errorString(); // Configure SerialPort this->serialPort->setBaudRate(AbstractSerial::BaudRate4800); this->serialPort->setDataBits(AbstractSerial::DataBits8); this->serialPort->setFlowControl(AbstractSerial::FlowControlOff); this->serialPort->setParity(AbstractSerial::ParityNone); this->serialPort->setStopBits(AbstractSerial::StopBits1); The problem is, that if I run my application, it crashes immediately with exit code -1073741515 (application failed to initialize properly). This is the same error I got using QextSerialPort under Windows XP (it worked with Windows Vista). If I build the QSerialDevice lib with release config and also my program, it crashes immediately but with exit code -1073741819 Can someone help me with this program or with another solution of getting a serial port to work with Qt (maybe another API or something?) Otherwise I have to use Windows API functions which would mean that my program won't work with UNIX systems.. If you have a solution for the problem with QextSerialPort under WinXP SP3, they are also welcome ;) Best Regards, Tobias

• How to set SGEN toolpath in Msbuild to target 3.5 framework

  - by Craig Shearer

  I've just upgraded a project from VS2008 to VS2010 but I'm still targeting the 3.5 framework. In my project file I have a custom task to run SGEN to generate my XmlSerializers.dll. However the version of sgen being run targets the 4.0 framework. As a result, when I run my application I get the error message: "Could not load file or assembly 'XXXX.XXXX.XmlSerializers' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded." The Sgen task looks like this: <Target Name="AfterBuild" DependsOnTargets="AssignTargetPaths;Compile;ResolveKeySource" Inputs="$(MSBuildAllProjects);@(IntermediateAssembly)" Outputs="$(OutputPath)$(_SGenDllName)"> <!-- Delete the file because I can't figure out how to force the SGen task. --> <Delete Files="$(TargetDir)$(TargetName).XmlSerializers.dll" ContinueOnError="true" /> <SGen BuildAssemblyName="$(TargetFileName)" BuildAssemblyPath="$(OutputPath)" References="@(ReferencePath)" ShouldGenerateSerializer="true" UseProxyTypes="false" KeyContainer="$(KeyContainerName)" KeyFile="$(KeyOriginatorFile)" DelaySign="$(DelaySign)" ToolPath="$(SGenToolPath)"> <Output TaskParameter="SerializationAssembly" ItemName="SerializationAssembly" /> </SGen> </Target> There's the ToolPath="$(SGenToolPath)". How do I make it run the version that targets 3.5? There's a similar question here but it doesn't help me much.

• SFx Server Did Not Reply

  - by user2956426

  have the following problem : For a project I've tentatively created a Silverlight 5 web application and successfully integrated a WCF service. So far so good , in the Visual Studio 2012 environment everything works as intended. The data is processed. Now I wanted to see if it all works well on IIS 7.5 . When I called the test page and spoke to the WCF service Error 405 - Method not allowed occures. After searching I solved the problem with a module allocation for *.svc .                       So, then comes the error 405 although no longer , and the service also reports the status 200 - OK . Unfortunately, the application still does not work . Now this error is reported in Silverlight : The server doenst reply a meaningful response , which may be caused by a non- matching agreement , a premature session shutdown or an internal server error . No idea what I must adjust or change now. Have read on one of the few sites on the topic that is ClientConfig blame, as they would continue as a reference for the *.xap file is valid after publishing , and not used WebConfig ... But according to the error message above, it seems to be problem in the ServiceModel.dll ... Please , can anyone help me resolve this error? Thank you, Roland I uploaded my project. Maybe someone can solve the issues in there or can check my config-files. http://www.file-upload.net/download-8261762/CiFls.zip.html

• How to troubleshoot errors with TeamCity

  - by Tomas Lycken

  I'm following this guide to set up a small environment for source control and automated builds - mostly for learning what it is and how it works, but also for using in those of my hobby projects that I believe will actually be useful some day. However, at the step where he commits and builds, I fail to get a success status in the TeamCity history log. I keep getting the error described in the stack trace below. I have verified with Windows Explorer that the solution file it can't find is actually there, so I really don't know what to do. How do I fix/troubleshoot this?

• Common Access Card (CAC) Authentication Using Java

  - by Paul

  I'm bascially looking for someplace to start learning how to interface with a government CAC card using java. Ultimately, my goal is to find out how to use CAC card authentication (by PIN number) to authorize access to a website hosted using a Tomcat/J2EE server. But I'll need somewhere to start. So I figure I'd start by writing a small java program to simply read the CAC card information from the CAC card which is inserted into a card reader on my keyboard (DELL keyboard with CAC reader above the numeric keypad). By searching google, I found the cacard java project (https://cacard.dev.java.net/) which was replaced by the OpenSSO project. But I can't seem to find sample code of how to use it to connect to a card, read from a card, etc. Does anyone know where I can find some sample code so that I can start learning how to interact with a CAC card using java? Thanks EDIT: After researching more, I was thinking, would I be able to just set clientAuth="true" in the connector element in the server.xml file? http://tomcat.apache.org/tomcat-6.0-doc/ssl-howto.html clientAuth: Set this value to true if you want Tomcat to require all SSL clients to present a client Certificate in order to use this socket.

• SPException: Catastrophic failure (Exception from HRESULT: 0x8000FFF (E_UNEXPECTED) in Sharepoint

  - by BeraCim

  I've been trying to programmatically copy custom content type and its custom columns from one web to another for some time now, and I always get different errors or exceptions every time. After yet more tries, I received more strange and cryptic exception from Sharepoint after clicking onto a newly copied custom column in a custom content type. I checked the logs, and this is what I got: Unknown SPRequest erorr occurred. More information: 0x80070002 Unable to locate the xml-definition for FieldName with FieldId 'guid without braces', exception: Microsoft.SharePoint.SPException: Catastrophic failure (Exception from HRESULT: 0x8000FFF (E_UNEXPECTED)) ---> System.Runtime.InteropServices.COMException... ... at Microsoft.SharePoint.Library.SPRequestInternalClass.GetGlobalContentTypeXml(String bstrUrl, Int32 type, UInt 32 lcid, Object varIdBytes...

I'm confused with what Sharepoint is trying to do here, and why a simple process of copying a custom content type from one web to another just wouldn't work in contrast to the information found on the web e.g. this. Appreciate any help to get over this problem. Thanks.

• SPFileVersionCollection - why versions are sorted in mixed order?

  - by Janis Veinbergs

  SPFileVersionCollection and SPListItemVersionCollection versioning seems inconsistent to me. Inconsistency wouldn't be a problem to me, but sort order is. SPListItemVersionCollection I can understand versioning of ListItems as they are stored in descending order: SPContext.Current.ListItem.Versions.Count -> 5 SPContext.Current.ListItem.Versions[0].VersionId -> 1026 (2.2 latest version) SPContext.Current.ListItem.Versions[1].VersionId -> 1025 (2.1) SPContext.Current.ListItem.Versions[2].VersionId -> 1024 (2.0) ... [4].VersionId -> (oldest version) SPFileVersionCollection However I can't understand how version numbers are saved for a document library item: SPContext.Current.ListItem.File.Versions.Count -> 4 SPContext.Current.ListItem.File.Versions[0].ID -> 512 (1.0 oldest one) SPContext.Current.ListItem.File.Versions[1].ID -> 513 (1.1) SPContext.Current.ListItem.File.Versions[2].ID -> 1025 (2.1 latest version) SPContext.Current.ListItem.File.Versions[3].ID -> 1024 (2.0 (EDIT: IsCurrentVersion = True)) They are nor in ascending order, nor descending, but something mixed. Is there any reason for SharePoint team to decide to store SPFile versions like that? And do they expect that I write my own method to get latest version or is there a builtin one for that? A note: Let me point out that SPListItem.File is not null for document library items.

• Problems with builds on TFS 2010 and resolving dependencies

  Hi I have a project that works great on my machine (and production servers). It's a VS2010 project running C#3.5. When letting my build server build the solution it can't resolve a couple of my third party dll's. Error message: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets(1360,9): warning MSB3268: The primary reference "Third.Party.Assembly, Version=50.11.2.0, Culture=neutral, PublicKeyToken=0561a7c6dbd6f0ea, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "Microsoft.VisualBasic.Compatibility, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v3.5". To resolve this problem, either remove the reference "Third.Party.Assembly, Version=50.11.2.0, Culture=neutral, PublicKeyToken=0561a7c6dbd6f0ea, processorArchitecture=MSIL" or retarget your application to a framework version which contains "Microsoft.VisualBasic.Compatibility, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". [d:\Builds\3\mySolution.sln] Everything compiles and runs great on my machine, but the build server seem to struggle. I think the Third.Party.Assembly is written in VB.net. Since the assembly is third party I can't remove the reference to "Microsoft.VisualBasic.Compatibility" and since I don't get any warnings on my computer could it really be that I'm running v3.5? Any suggestions? /Jimmy

• android.intent.action.SCREEN_ON doesn't work as a receiver intent filter

  - by Jim Blackler

  I'm trying to get a BroadcastReceiver invoked when the screen is turned on. In my AndroidManifest.xml I have specified : <receiver android:name="IntentReceiver"> <intent-filter> <action android:name="android.intent.action.SCREEN_ON"></action> </intent-filter> </receiver> However it seems the receiver is never invoked (breakpoints don't fire, log statements ignored). I've swapped out SCREEN_ON for BOOT_COMPLETED for a test, and this does get invoked. This is in a 1.6 (SDK level 4) project. A Google Code Search revealed this, I downloaded the project and synced it, converted it to work with latest tools, but it too is not able to intercept that event. http://www.google.com/codesearch/p?hl=en#_8L9bayv7qE/trunk/phxandroid-intent-query/AndroidManifest.xml&q=android.intent.action.SCREEN_ON Is this perhaps no longer supported? Previously I have been able to intercept this event successfully with a call to Context.registerReceiver() like so registerReceiver(new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // ... } }, new IntentFilter(Intent.ACTION_SCREEN_ON)); However this was performed by a long-living Service. Following sage advice from CommonsWare I have elected to try to remove the long-living Service and use different techniques. But I still need to detect the screen off and on events.

• xcode linker error on iPhone app (Only on simulator)

  - by RexOnRoids

  Im getting this linker error that won't let me compile. It only happens on the simulator. KEY POINTS: - Happens only in simulator - Similar to THIS question, but found no FRAMEWORK_SEARCH_PATHS in my .pbxproj file - Though my OS is 10.6.2, I had to build target 1.5 to avoid other linker errors - libxml2.dylib IS required and is in my Frameworks group - The other cited libraries I have never heard of. - Tried bringing in those other Libs under frameworks, didn't solve.

• How can I discover zeroconf (Bonjour) services on Android? I'm having trouble with jmDNS.

  - by Peter Kirn

  I'm working with a Droid / Android 2.0.1 and encountering an issue apparently many people have: I'm unable to discover services using the one pure-Java zeroconf library I know of, jmDNS. (Apple's Bonjour, while it works on Linux and Windows Java, I believe would be harder to port to Android because of reliance on native code.) I can create services, but not discover them. I'm trying to make sense of what's going on. There is an ongoing issue report here; related to multicast and IPv6, but seems to be throwing users of jmDNS, too: http://code.google.com/p/android/issues/detail?id=2323 Any idea why this person might be having success? See comment 22 in the bug report. (I'm new to SO, so can't post more than one URL.) I have tested their code, but without any luck. Has anyone successfully accomplished zeroconf service discovery on Android, using jmDNS or another library? Is it possible my discovery issue is related to the IPv6 multicast problem?

• MVC2 client/server validation of DateTime/Date using DataAnnotations

  - by Thomas

  The following are true: One of my columns (BirthDate) is of type Date in SQL Server. This very same column (BirthDate) is of type DateTime when EF generates the model. I am using JQuery UI Datepicker on the client side to be able to select the BirthDate. I have the following validation logic in my buddy class: [Required(ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Required")] [RegularExpression(@"\b(0?[1-9]|1[012])[/](0?[1-9]|[12][0-9]|3[01])[/](19|20)?[0-9]{2}\b", ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Invalid")] public virtual DateTime? BirthDate { get; set; } There are two issues with this: This will not pass server side validation (if I enable client side validation it works just fine). I am assuming that this is because the regular expression doesn't take into account hours, minutes, seconds as the value in the text box has already been cast as a DateTime on the server by the time validation occurs. If data already exists in the database and is read into the model and displayed on the page the BirthDate field shows hours, minutes, seconds in my text box (which I don't want). I can always use ToShortDateString() but I am wondering if there is some cleaner approach that I might be missing. Thanks

• Managing a file-based public maven repository

  - by Roland Ewald

  I am looking for an easy way to manage a public file-based Maven repository. While we are using the open-source version of Artifactory internally, we now want to put a file-based repository of our published artifacts (and their dependencies) on a separate machine that is publicly available. There are several ways how to do this, but none of them seems ideal: Use Maven Dependency plugin: if it is configured correctly and executed with the goal dependency:copy-dependencies for the release-module of our project, it creates a local repository structure that is fine, but this structure does not contain the meta-data.xml files, nor the hash-sums. Use Artifactory to export repo: AFAIK Artifactory only allows to export a repository as a whole. This would include the non-published modules from our project (which would then need to be deleted manually). Also, all dependencies are sitting in another repository, so this needs to be done twice, and many dependencies are not even required by a published artifact (only by artifacts that are still for internal use only). Nevertheless, this method would also include the meta-data.xml files and the hash-sums for all files. To set up an initial version of the repository, I used a mixture of both methods: I first created the Maven repository for all required dependencies via dependency:copy-dependencies and then wrote a script to cherry-pick the meta-data.xml files (etc.) from Artifactory. This is terribly cumbersome, isn't there a better way to solve this? Maybe there is another Maven 3 - plugin that I am unaware of, or some other command-line tool that does the job? I basically just need a simple way to create a Maven repository that contains all artifacts a given artifact depends on (and no more), and also contains all meta-data expected in a remote repository. Any ideas?

• How should I distribute a pre-built perl module, and what version of perl do I build for?

  - by Mike Ellery

  This is probably a multi-part question. Background: we have a native (c++) library that is part of our application and we have managed to use SWIG to generate a perl wrapper for this library. We'd now like to distribute this perl module as part of our application. My first question - how should I distribute this module? Is there a standard way to package pre-built perl modules? I know there is ppm for the ActiveState distro, but I also need to distribute this for linux systems. I'm not even sure what files are required to distribute, but I'm guessing it's the pm and so files, at a minimum. My next question - it looks like I might need to build my module project for each version of perl that I want to support. How do I know which perl versions I should build for? Are there any standard guidelines... or better yet, a way to build a package that will work with multiple versions of perl? Sorry if my questions make no sense - I'm fairly new to the compiled module aspects of perl. CLARIFICATION: the underlying compiled source is proprietary (closed source), so I can't just ship source code and the appropriate make artifacts for the package. Wish I could, but it's not going to happen in this case. Thus, I need a sane scheme for packaging prebuilt binary files for my module.

• Rally Rest .NET API throws KeyNotFoundException when posting a new defect without required field value

  - by Triet Pham

  I've tried to post a new defect to Rally via Rest .net api by the following code: var api = new RallyRestApi("<myusername>", "<mypassword>", "https://community.rallydev.com"); var defect = new DynamicJsonObject(); defect["Name"] = "Sample Defect"; defect["Description"] = "Test posting defect without required field value"; defect["Project"] = "https://trial.rallydev.com/slm/webservice/1.29/project/5808130051.js"; defect["SubmittedBy"] = "https://trial.rallydev.com/slm/webservice/1.29/user/5797741589.js"; defect["ScheduleState"] = "In-Progress"; defect["State"] = "Open"; CreateResult creationResult = api.Create("defect", defect); But the api throws a weird exception: System.Collections.Generic.KeyNotFoundException was unhandled Message=The given key was not present in the dictionary. Source=mscorlib StackTrace: at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at Rally.RestApi.DynamicJsonObject.GetMember(String name) at Rally.RestApi.DynamicJsonObject.TryGetMember(GetMemberBinder binder, Object& result) at CallSite.Target(Closure , CallSite , Object ) at System.Dynamic.UpdateDelegates.UpdateAndExecute1[T0,TRet](CallSite site, T0 arg0) at Rally.RestApi.RallyRestApi.Create(String type, DynamicJsonObject obj) at RallyIntegrationSample.Program.Main(String[] args) in D:\Projects\qTrace\References\Samples\RallyIntegrationSample\Program.cs:line 24 The problem is when i checked out the trace log file of Rally, it showed exactly what wrong in the posting request: Rally.RestApi Post Response: { "CreateResult": { "_rallyAPIMajor":"1", "_rallyAPIMinor":"29", "Errors":["Validation error: Defect.Severity should not be null"], "Warnings":[] } } Instead of given the proper CreateResult object with according errors information in its property, the Rally Rest .Net Api throws an unexpected exception. Is that a mistake in Rally rest .net api or should i do any extra steps to get the CreatResult seamlessly in case of any errors returned by Rally service? Many thanks for your helps.

• Should I buy Obout? Help, Please.

  - by Ramiz Uddin

  We started a new project and the nature of the project is very interactive and a Rich UI is required. We would need a set of controls that would require for Rich UI development. I found Obout while googling. I never heard about them and never seen fellow members telling me such name except Telerik, ComponentOne, NetAdvantage. These are the famous names we heard but no this one. But, the controls give a positive feeling. But as two things matter always when you are buying some services: How good are their customer support? and How much feasible their price is? Another, How quickly they release patches/updates? As, what if we find a bug or an error during development what will gonna happen? Do they provide a quick solution for this? I hope you understand my query. I'm bit confused making a decision here. I need your assistance, experience and feedback. Please, assist! Thanks.
