  • How to make a Custom Data Generator for SQL XML DataType.

    - by Keith Sirmons
    Howdy, I am using Visual Studio 2010 and am playing around with the Database Projects. I am creating a DataGenerationPlan to insert data into a simple table, in which one of the column datatypes is XML. Out of the box, the generation plan uses the Regular Expression generator and generates something like this : HGcSv9wa7yM44T9x5oFT4pmBkEmv62lJ7OyAmCnL6yqXC2X.......... I am looking at creating a custom data Generator for this data type and have followed this site for the basics: http://msdn.microsoft.com/en-us/library/aa833244.aspx This example works if I am creating a string datatype and using it for a nvarchar datatype. What do I need to change to hook this Generator to the XML Datatype? Below are my code files. The string property works for nvarchar. The XElement property does not work for the xml datatype, and the RecordXMLDataGenerator is not listed as an option in the Generator column for the generation plan. CustomDataGenerators: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Data.Schema.Tools.DataGenerator; using Microsoft.Data.Schema.Extensibility; using Microsoft.Data.Schema; using Microsoft.Data.Schema.Sql; using System.Xml.Linq; namespace CustomDataGenerators { [DatabaseSchemaProviderCompatibility(typeof(SqlDatabaseSchemaProvider))] public class RecordXMLDataGenerator : Generator { private XElement _RecordData; [Output(Description = "Generates string of XML Data for the Record.", Name = "RecordDataString")] public string RecordDataString { get { return _RecordData.ToString(SaveOptions.None); } } [Output(Description = "Generates XML Data for the Record.", Name = "RecordData")] public XElement RecordData { get { return _RecordData; } } protected override void OnGenerateNextValues() { base.OnGenerateNextValues(); XElement element = new XElement("Root", new XElement("Children1", 1), new XElement("Children6", 6) ); _RecordData = element; } } } XML Extensions File: <?xml version="1.0" encoding="utf-8" ?> <extensions assembly="" version="1" xmlns="urn:Microsoft.Data.Schema.Extensions" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:Microsoft.Data.Schema.Extensions Microsoft.Data.Schema.Extensions.xsd"> <extension type="CustomDataGenerators.RecordXMLDataGenerator" assembly="CustomDataGenerators, Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx" enabled="true"/> </extensions> Table.sql: CREATE TABLE [dbo].[Record] ( id int IDENTITY (1,1) NOT NULL, recordData xml NULL, userId int NULL, test nvarchar(max) NULL, rowver rowversion NULL, CONSTRAINT pk_RecordID PRIMARY KEY (id) )

  • Failing to install activerecord-jdbcmysql-adapter gem

    - by Phil Sturgeon
    I am trying to follow the basic "Create a blog in 20 minutes" Rails screencast but have hit a stumbling block already. When I try to rake db:migrate I get errors about the gem activerecord-jdbcmysql-adapter not being installed. When I try to install it, I am told it doesn't exist. If I try to simply gem install mysql I get all sorts of madness appearing. I am running this on Mac OS X 10.6.2 and my installation was all done through gem. My basic setup works (Hello world!).

  • PHP SASL(PECL) sasl_server_init(app) works with CLI but not with ApacheModule

    - by ZokRadonh
    I have written a simple auth script so that Webusers can type in their username and password and my PHP script verifies them by SASL. The SASL Library is initialized by php function sasl_server_init("phpfoo"). So phpfoo.conf in /etc/sasl2/ is used. phpfoo.conf: pwcheck_method: saslauthd mech_list: PLAIN LOGIN log_level: 9 So the SASL library now tries to connect to saslauthd process by socket. saslauthd command line looks like this: /usr/sbin/saslauthd -r -V -a pam -n 5 So saslauthd uses PAM to authenticate. In the php script I have created sasl connection by sasl_server_new("php", null, "myRealm"); The first argument is the servicename. So PAM uses the file /etc/pam.d/php to see for further authentication information. /etc/pam.d/php: auth required pam_mysql.so try_first_pass=0 config_file=/etc/pam.d/mysqlconf.nss account required pam_permit.so session required pam_permit.so mysqlconf.nss has all information that is needed for a useful MySQL Query to user table. All of this works perfectly when I run the script by command line. php ssasl.php But when I call the same script via webbrowser(php apache module) I get an -20 return code (SASL_NOUSER). In /var/log/messages there is May 18 15:27:12 hostname httpd2-prefork: unable to open Berkeley db /etc/sasldb2: No such file or directory I do not have anything with a Berkeley db for authentication with SASL. I think authentication using /etc/sasldb2 is the default setting. In my opinion it does not read my phpfoo.conf file. For some reason the php-apache-module ignores the parameter in sasl_server_init("phpfoo"). My first thought was that there is a permission issue. So back in shell: su -s /bin/bash wwwrun php ssasl.php "Authentication successful". - No file-permission issue. In the source of the sasl-php-extension we can find: PHP_FUNCTION(sasl_server_init) { char *name; int name_len; if (zend_parse_parameters(1 TSRMLS_CC, "s", &name, &name_len) == FAILURE) { return; } if (sasl_server_init(NULL, name) != SASL_OK) { RETURN_FALSE; } RETURN_TRUE; } This is a simple pass through of the string. Are there any differences between the PHP CLI and PHP ApacheModule version that I am not aware of? Anyway, there are some interesting log entries when I run PHP in CLI mode: May 18 15:44:48 hostname php: SQL engine 'mysql' not supported May 18 15:44:48 hostname php: auxpropfunc error no mechanism available May 18 15:44:48 hostname php: _sasl_plugin_load failed on sasl_auxprop_plug_init for plugin: sqlite May 18 15:44:48 hostname php: sql_select option missing May 18 15:44:48 hostname php: auxpropfunc error no mechanism available May 18 15:44:48 hostname php: _sasl_plugin_load failed on sasl_auxprop_plug_init for plugin: sql Those lines are followed by lines of saslauthd and PAM which results in authentication success.(I do not get any of them in ApacheModule mode) Looks like that he is trying auxprop pwcheck before saslauthd. I have no other .conf file in /etc/sasl2. When I change the parameter of sasl_server_init to something other then I get the same error in CLI mode as in ApacheModule mode.

  • Setting up NCover for NUnit in FinalBuilder

    - by Lasse V. Karlsen
    I am attempting to set up NCover for usage in my FinalBuilder project, for a .NET 4.0 C# project, but my final coverage output file contains no coverage data. I am using: NCover 3.3.2 NUnit 2.5.4 FinalBuilder 6.3.0.2004 All tools are the latest official as of today. I've finally managed to coax FB into running my unit tests under NCover for the .NET 4.0 project, so I get Tests run: 184, ..., which is correct. However, the final Coverage.xml file output from NCover is almost empty, and looks like this: <?xml version="1.0" encoding="utf-8"?> <!-- saved from NCover 3.0 Export url='http://www.ncover.com/' --> <coverage profilerVersion="3.3.2.6211" driverVersion="3.3.2" exportversion="3" viewdisplayname="" startTime="2010-04-22T08:55:33.7471316Z" measureTime="2010-04-22T08:55:35.3462915Z" projectName="" buildid="27c78ffa-c636-4002-a901-3211a0850b99" coveragenodeid="0" failed="false" satisfactorybranchthreshold="95" satisfactorycoveragethreshold="95" satisfactorycyclomaticcomplexitythreshold="20" satisfactoryfunctionthreshold="80" satisfactoryunvisitedsequencepoints="10" uiviewtype="TreeView" viewguid="C:\Dev\VS.NET\LVK.IoC\LVK.IoC.Tests\bin\Debug\Coverage.xml" viewfilterstyle="None" viewreportstyle="SequencePointCoveragePercentage" viewsortstyle="Name"> <rebasedpaths /> <filters /> <documents> <doc id="0" excluded="false" url="None" cs="" csa="00000000-0000-0000-0000-000000000000" om="0" nid="0" /> </documents> </coverage> The output in FB log is: ... ***************** End Program Output ***************** Execution Time: 1,5992 s Coverage Xml: C:\Dev\VS.NET\LVK.IoC\LVK.IoC.Tests\bin\Debug\Coverage.xml NCover Success My configuration of the FB step for NCover: NCover what?: NUnit test coverage Command: C:\Program Files (x86)\NUnit 2.5.4\bin\net-2.0\nunit-console.exe Command arguments: LVK.IoC.Tests.dll /noshadow /framework:4.0.30319 /process=single /nothread Note: I've tried with and without the /process and /nothread options Working directory: %FBPROJECTDIR%\LVK.IoC.Tests\bin\Debug List of assemblies to profile: %FBPROJECTDIR%\LVK.IoC.Tests\bin\Debug\LVK.IoC.dll Note: I've tried just listing the name of the assembly, both with and without the extension. The documentation for the FB step doesn't help, as it only lists minor sentences for each property, and fails to give examples or troubleshooting hints. Since I want to pull the coverage results into NDepend to run build-time analysis, I want that file to contain the information I need. I am also using TestDriven, and if I right-click the solution file and select "Test with NCover", NCover-explorer opens up with coverage data, and if I ask it to show me the folder with coverage files, in there is an .xml file with the same structure as the one above, just with all the data that should be there, so the tools I have is certainly capable of producing it. Has anyone an idea of what I've configured wrong here?

  • Difficulty getting Saxon into XQuery mode instead of XSLT

    I'm having difficulty getting XQuery to work. I downloaded Saxon-HE 9.2. It seems to only want to work with XSLT. When I type: java -jar saxon9he.jar I get back usage information for XSLT.

  • C# Nested Property Accessing overloading OR Sequential Operator Overloading

    - by Tim
    Hey, I've been searching around for a solution to a tricky problem we're having with our code base. To start, our code resembles the following: class User { int id; int accountId; Account account { get { return Account.Get(accountId); } } } class Account { int accountId; OnlinePresence Presence { get { return OnlinePresence.Get(accountId); } } public static Account Get(int accountId) { // hits a database and gets back our object. } } class OnlinePresence { int accountId; bool isOnline; public static OnlinePresence Get(int accountId) { // hits a database and gets back our object. } } What we're often doing in our code is trying to access the account Presence of a user by doing var presence = user.Account.Presence; The problem with this is that this is actually making two requests to the database. One to get the Account object, and then one to get the Presence object. We could easily knock this down to one request if we did the following : var presence = UserPresence.Get(user.id); This works, but sort of requires developers to have an understanding of the UserPresence class/methods that would be nice to eliminate. I've thought of a couple of cool ways to be able to handle this problem, and was wondering if anyone knows if these are possible, if there are other ways of handling this, or if we just need to think more as we're coding and do the UserPresence.Get instead of using properties. Overload nested accessors. It would be cool if inside the User class I could write some sort of "extension" that would say "any time a User object's Account property's Presence object is being accessed, do this instead". Overload the . operator with knowledge of what comes after. If I could somehow overload the . operator only in situations where the object on the right is also being "dotted" it would be great. Both of these seem like things that could be handled at compile time, but perhaps I'm missing something (would reflection make this difficult?). Am I looking at things completely incorrectly? Is there a way of enforcing this that removes the burden from the user of the business logic? Thanks! Tim

  • XML to be validated against multiple xsd schemas

    - by Michael Rusch
    I'm writing the xsd and the code to validate, so I have great control here. I would like to have an upload facility that adds stuff to my application based on an xml file. One part of the xml file should be validated against different schemas based on one of the values in the other part of it. Here's an example to illustrate: <foo> <name>Harold</name> <bar>Alpha</bar> <baz>Mercury</baz> <!-- ... more general info that applies to all foos ... --> <bar-config> <!-- the content here is specific to the bar named "Alpha" --> </bar-config> <baz-config> <!-- the content here is specific to the baz named "Mercury" --> </baz> </foo> In this case, there is some controlled vocabulary for the content of <bar>, and I can handle that part just fine. Then, based on the bar value, the appropriate xml schema should be used to validate the content of bar-config. Similarly for baz and baz-config. The code doing the parsing/validation is written in Java. Not sure how language-dependent the solution will be. Ideally, the solution would permit the xml author to declare the appropriate schema locations and what-not so that s/he could get the xml validated on the fly in a sufficiently smart editor. Also, the possible values for <bar> and <baz> are orthogonal, so I don't want to do this by extension for every possible bar/baz combo. What I mean is, if there are 24 possible bar values/schemas and 8 possible baz values/schemas, I want to be able to write 1 + 24 + 8 = 33 total schemas, instead of 1 * 24 * 8 = 192 total schemas. Also, I'd prefer to NOT break out the bar-config and baz-config into separate xml files if possible. I realize that might make all the problems much easier, as each xml file would have a single schema, but I'm trying to see if there is a good single-xml-file solution.

  • Installing PyGraphViz on Windows, Python 2.7

    - by user574043
    I can't install pygraphviz on Windows XP. I'm using Python27.

  • WPF MVVM Pattern, ViewModel DataContext question

    - by orangecl4now
    I used this side to create my demo application http://windowsclient.net/learn/video.aspx?v=314683 The site was very useful in getting my started and in their example, they created a file called EmployeeRepository.cs which appears to be the source for the data. In their example, the data was hard-wired in code. So I'm trying to learn how to get the data from a data source (like a DB). In my specific case, I want to get the data from a Microsoft Access DB. (READ ONLY, So I'll only use SELECT commands). using System.Collections.Generic; using Telephone_Directory_2010.Model; namespace Telephone_Directory_2010.DataAccess { public class EmployeeRepository { readonly List<Employee> _employees; public EmployeeRepository() { if (_employees == null) { _employees = new List<Employee>(); } _employees.Add(Employee.CreateEmployee("Student One", "IT201", "Information Technology", "IT4207", "Building1", "Room650")); _employees.Add(Employee.CreateEmployee("Student Two", "IT201", "Information Technology", "IT4207", "Building1", "Room650")); _employees.Add(Employee.CreateEmployee("Student Three", "IT201", "Information Technology", "IT4207", "Building1", "Room650")); } public List<Employee> GetEmployees() { return new List<Employee>(_employees); } } } I found another example where an Access DB is used but it doesn't comply with MVVM. So I was trying to figure out how to add the DB file to the project, how to wire it up and bind it to a listbox (i'm not that far yet). Below is my modified file using System.Collections.Generic; using Telephone_Directory_2010.Model; // integrating new code with working code using Telephone_Directory_2010.telephone2010DataSetTableAdapters; using System.Windows.Data; namespace Telephone_Directory_2010.DataAccess { public class EmployeeRepository { readonly List<Employee> _employees; // start // integrating new code with working code private telephone2010DataSet.telephone2010DataTable employeeTable; private CollectionView dataView; internal CollectionView DataView { get { if (dataView == null) { dataView = (CollectionView) CollectionViewSource.GetDefaultView(this.DataContext); } return dataView; } } public EmployeeRepository() { if (_employees == null) { _employees = new List<Employee>(); } telephone2010TableAdapter employeeTableAdapter = new telephone2010TableAdapter(); employeeTable = employeeTableAdapter.GetData(); this.DataContext = employeeTable; } public List<Employee> GetEmployees() { return new List<Employee>(_employees); } } } I get the following error messages when building Error 1 'Telephone_Directory_2010.DataAccess.EmployeeRepository' does not contain a definition for 'DataContext' and no extension method 'DataContext' accepting a first argument of type 'Telephone_Directory_2010.DataAccess.EmployeeRepository' could be found (are you missing a using directive or an assembly reference?)

  • imagick showing script url instead of image

    - by Raz
    Hi, currently i'm trying to use imagick to generate some images without saving them on the server and then outputting to the browser, my method of choice was image magic with the imagick extension for php. I read the documentation, and i'm sure the package is installed on my machine (windows xp, with xampp). the class is installed imagick module enabled imagick module version 2.0.0-alpha imagick classes Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator ImageMagick version ImageMagick 6.3.3 04/21/07 Q16 http://www.imagemagick.org ImageMagick release date 04/21/07 ImageMagick Number of supported formats: 164 ImageMagick Supported formats A, ART, AVI, AVS, B, BIE, BMP, BMP2, BMP3, C, CACHE, CAPTION, CIN, CIP, CLIP, CLIPBOARD, CMYK, CMYKA, CUR, CUT, DCM, DCX, DFONT, DPS, DPX, EMF, EPDF, EPI, EPS, EPS2, EPS3, EPSF, EPSI, EPT, EPT2, EPT3, FAX, FITS, FRACTAL, FTS, G, G3, GIF, GIF87, GRADIENT, GRAY, HISTOGRAM, HTM, HTML, ICB, ICO, ICON, INFO, JBG, JBIG, JNG, JP2, JPC, JPEG, JPG, JPX, K, LABEL, M, M2V, MAP, MAT, MATTE, MIFF, MNG, MONO, MPC, MPEG, MPG, MSL, MSVG, MTV, MVG, NULL, O, OTB, OTF, PAL, PALM, PAM, PATTERN, PBM, PCD, PCDS, PCL, PCT, PCX, PDB, PDF, PFA, PFB, PGM, PGX, PICON, PICT, PIX, PJPEG, PLASMA, PNG, PNG24, PNG32, PNG8, PNM, PPM, PREVIEW, PS, PS2, PS3, PSD, PTIF, PWP, R, RAS, RGB, RGBA, RGBO, RLA, RLE, SCR, SCT, SFW, SGI, SHTML, STEGANO, SUN, SVG, SVGZ, TEXT, TGA, THUMBNAIL, TIFF, TILE, TIM, TTC, TTF, TXT, UIL, UYVY, VDA, VICAR, VID, VIFF, VST, WBMP, WMF, WMFWIN32, WMZ, WPG, X, XBM, XC, XCF, XPM, XV, XWD, Y, YCbCr, YCbCrA, YUV this is from the phpinfo so i know i have it installed, the thing is when i try to generate an image and save it, it works flawlessly, but when i try to output the image directly, i get the script url as an image $draw = new ImagickDraw(); $draw->setFont('AnkeCalligraph.TTF'); $draw->setFontSize(52); $draw->annotation(110, 110, "Hello World!"); $draw->annotation(50, 220, "Hello World!"); $canvas = new Imagick('./pictures/test_live.PNG'); $canvas->drawImage($draw); $canvas->setImageFormat('png'); header("Content-Type: image/png"); echo $canvas; this is the code used. if i use writeimage, then the file on the server is created with no problems. does anyone have any ideas what i'm doing wrong ?

  • Challenge: Neater way of currying or partially applying C#4's string.Join

    - by Damian Powell
    Background I recently read that .NET 4's System.String class has a new overload of the Join method. This new overload takes a separator, and an IEnumerable<T> which allows arbitrary collections to be joined into a single string without the need to convert to an intermediate string array. Cool! That means I can now do this: var evenNums = Enumerable.Range(1, 100) .Where(i => i%2 == 0); var list = string.Join(",",evenNums); ...instead of this: var evenNums = Enumerable.Range(1, 100) .Where(i => i%2 == 0) .Select(i => i.ToString()) .ToArray(); var list = string.Join(",", evenNums); ...thus saving on a conversion of every item to a string, and then the allocation of an array. The Problem However, being a fan of the functional style of programming in general, and method chaining in C# in particular, I would prefer to be able to write something like this: var list = Enumerable.Range(1, 100) .Where(i => i%2 == 0) .string.Join(","); This is not legal C# though. The closest I've managed to get is this: var list = Enumerable.Range(1, 100) .Where(i => i%2 == 0) .ApplyTo( Functional.Curry<string, IEnumerable<object>, string> (string.Join)(",") ); ...using the following extension methods: public static class Functional { public static TRslt ApplyTo<TArg, TRslt>(this TArg arg, Func<TArg, TRslt> func) { return func(arg); } public static Func<T1, Func<T2, TResult>> Curry<T1, T2, TResult>(this Func<T1, T2, TResult> func) { Func<Func<T1, T2, TResult>, Func<T1, Func<T2, TResult>>> curried = f => x => y => f(x, y); return curried(func); } } This is quite verbose, requires explicit definition of the parameters and return type of the string.Join overload I want to use, and relies upon C#4's variance features because we are defining one of the arguments as IEnumerable rather than IEnumerable. The Challenge Can you find a neater way of achieving this using the method-chaining style of programming?

  • Http Modules are called on every request when using mvc/routing module

    - by MartinF
    I am developing a http module that hooks into the FormsAuthentication Module through the Authenticate event. While debugging i noticed that the module (and all other modules registered) gets hit every single time the client requests a resource (also when it requests images, stylesheets, javascript files (etc.)). This happens both when running on a IIS 7 server in integrated pipeline mode, and debugging through the webdev server (in non- integrated pipeline mode) As i am developing a website with a lot images which usually wont be cached by the client browser it will hit the modules a lot of unnessecary times. I am using MVC and its routing mechanishm (System.Web.Routing.UrlRoutingModule). When creating a new website the runAllManagedModulesForAllRequests attribute for the IIS 7 (system.webServer) section is per default set to true in the web.config, which as the name indicates make it call all modules for every single request. If i set the runAllManagedModulesForAllRequests attribute to false, no modules will get called. It seems that the reason for this is because of the routing module or mvc (dont know excactly why), which causes that the asp.net (aspx) handler never gets called and therefore the events and the modules never gets called (one time only like supposed). I tested this by trying to call "mydomain.com/Default.aspx" instead of just "mydomain.com/" and correctly it calls the modules only once like it is supposed. How do i fix this so it only calls the modules once when the page is requested and not also when all other resources are requested ? Is there some way i can register that all requests should fire the asp.net (aspx) handler, except requests for specific filetype extensions ? Of course that wont fix the problem if i choose to go with urls like /content/images/myimage123 for the images (without the extension). But i cant think of any other way to fix it. Is there a better way to solve this problem ? I have tried to set up an ignoreRoute like this routes.IgnoreRoute("content/{*pathInfo}"); where the content folder contains all the images, javascripts and stylesheets in seperat subfolders, but it doesnt seem to change anything. I can see there a many different possibilites when setting up a handler but I cant seem to figure out how it should be possible to setup one that will make it possible to use the routing module and have urls like /blog/post123 and not call the modules when requesting images, javascripts and stylesheets (etc.). Hope anyone out there can help me ? Martin

  • What does this WCF error mean: "Custom tool warning: Cannot import wsdl:portType"

    - by stiank81
    I created a WCF service library project in my solution, and have service references to this. I use the services from a class library, so I have references from my WPF application project in addition to the class library. Services are set up straight forward - only changed to get async service functions. Everything was working fine - until I wanted to update my service references. It failed, so I eventually rolled back and retried, but it failed even then! So - updating the service references fails without doing any changes to it. Why?! The error I get is this one: Custom tool error: Failed to generate code for the service reference 'MyServiceReference'. Please check other error and warning messages for details. The warning gives more information: Custom tool warning: Cannot import wsdl:portType Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.DataContractSerializerMessageContractImporter Error: List of referenced types contains more than one type with data contract name 'Patient' in namespace 'http://schemas.datacontract.org/2004/07/MyApp.Model'. Need to exclude all but one of the following types. Only matching types can be valid references: "MyApp.Dashboard.MyServiceReference.Patient, Medski.Dashboard, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" (matching) "MyApp.Model.Patient, MyApp.Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" (matching) XPath to Error Source: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:portType[@name='ISomeService'] There are two similar warnings too saying: Custom tool warning: Cannot import wsdl:binding Detail: There was an error importing a wsdl:portType that the wsdl:binding is dependent on. XPath to wsdl:portType: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:portType[@name='ISomeService'] XPath to Error Source: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:binding[@name='WSHttpBinding_ISomeService'] And the same for: Custom tool warning: Cannot import wsdl:port .. I find this all confusing.. I don't have a Patient class on the client side Dashboard except the one I got through the service reference. So what does it mean? And why does it suddenly show? Remember: I didn't even change anything! Now, the solution to this was found here, but without an explanation to what this means. So; in the "Configure service reference" for the service I uncheck the "Reuse types in the referenced assemblies" checkbox. Rebuilding now it all works fine without problems. But what did I really change? Will this make an impact on my application? And when should one uncheck this? I do want to reuse the types I've set up DataContract on, but no more. Will I still get access to those without this checked?

  • Creating a bundle - What's going wrong?

    - by joeylange
    Hello everyone, I've got a relatively simple one here. I'm making bundles to live inside the Resources folder of my application (and possibly in the Application Support folder). These bundles will contain template information for the data the application handles. I've constructed a bundle, with extension "booksprintstyle", and the directory structure is up to spec. I have an Info.plist all set and I think I've filled in all the values I need to. Do I need to change something in my App to have these folders-with-extensions recognized as bundle files, or am I missing something in my bundle structure? I noticed that some bundles have a file called PkgInfo; is that important? Below is the Info.plist from my bundle. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleDevelopmentRegion</key> <string>English</string> <key>CFBundleGetInfoString</key> <string>1.0, Copyright © 2009 Joey Lange</string> <key>CFBundleIdentifier</key> <string>net.atherial.books.exporter.printingpress.printstyle</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundleName</key> <string>Books Print Style - Generic</string> <key>CFBundlePackageType</key> <string>BNDL</string> <key>CFBundleShortVersionString</key> <string>1.0</string> <key>CFBundleSignature</key> <string>????</string> <key>CFBundleDisplayName</key> <string>Books Print Style - Generic</string> <key>NSHumanReadableCopyright</key> <string>Copyright © 2009 Joey Lange</string> <key>CFBundleVersion</key> <string>1.0</string> </dict> </plist>

  • json problems with making a ruby on rails application

    - by Prince Merdz
    So I'm using Bitnami to learn Ruby on Rails. I have also previously tried the manual installation for ruby and rails and was met by the same problem so I thought I should try first the easy package deal of Bitnami. Anyway my problem with json is that it causes the bundle install to fail. First the auto bundle install that rails new does fails because of an ssl error. Which is easily solved by changing the source in the gemfile which is https to http. However when I try to bundle install it does another error when it tries to install json.

  • "RFC 2833 RTP Event" Consecutive Events and the E "End" Bit

    - by brian_d
    Hello, I can send out a RFC 2833 dtmf event as outlined at http://www.ietf.org/rfc/rfc2833.txt When I do set the E "End" bit, but leave it as 0, I get the following behaviour: If for example keys 7874556332111111145855885#3 were pressed, then ALL events would be sent and show up in a program like wireshark, however only 87456321458585#3 would sound. So the first key (which I figure could be a separate issue) and any repeats of an event (ie 11111) are failing to sound. In section 3.9, figure 2 of the above linked document, they give a 911 example. Here all but the last event have the E bit set. When I set the bit for all numbers, I never get an event to sound. I have thought of a couple possible thing but do not know if they are the reason: 1) figure 2 shows payload types of 96 and 97 sent. I have not nor know how to exactly. In section 3.8, codes 96 and 97 are described as "the dynamic payload types 96 and 97 have been assigned for the redundancy mechanism and the telephone event payload respectively" 2) In section 3.5, "E:", "A sender MAY delay setting the end bit until retransmitting the last packet for a tone, rather than on its first transmission" Does anyone have an idea of how to actually do this? I have also fiddled around with timestamp intervals and the RTP marker. Any help is greatly appreciated. Here is a sample wireshark event capture of the relevant areas: 6590 31.159045000 xx.x.x.xxx --.--.---.-- RTP EVENT Payload type=RTP Event, DTMF Pound # (end) Real-Time Transport Protocol Stream setup by SDP (frame 6225) Setup frame: 6225 Setup Method: SDP 10.. .... = Version: RFC 1889 Version (2) ..0. .... = Padding: False ...0 .... = Extension: False .... 0000 = Contributing source identifiers count: 0 0... .... = Marker: False Payload type: telephone-event (101) Sequence number: 0 Extended sequence number: 65536 Timestamp: 0 Synchronization Source identifier: 0x15f27104 (368210180) RFC 2833 RTP Event Event ID: DTMF Pound # (11) 1... .... = End of Event: True .0.. .... = Reserved: False ..00 0000 = Volume: 0 Event Duration: 2048

  • How can arguments to variadic functions be passed by reference in PHP?

    - by outis
    Assuming it's possible, how would one pass arguments by reference to a variadic function without generating a warning in PHP? We can no longer use the '&' operator in a function call, otherwise I'd accept that (even though it would be error prone, should a coder forget it). What inspired this is are old MySQLi wrapper classes that I unearthed (these days, I'd just use PDO). The only difference between the wrappers and the MySQLi classes is the wrappers throw exceptions rather than returning FALSE. class DBException extends RuntimeException {} ... class MySQLi_throwing extends mysqli { ... function prepare($query) { $stmt = parent::prepare($query); if (!$stmt) { throw new DBException($this->error, $this->errno); } return new MySQLi_stmt_throwing($this, $query, $stmt); } } // I don't remember why I switched from extension to composition, but // it shouldn't matter for this question. class MySQLi_stmt_throwing /* extends MySQLi_stmt */ { protected $_link, $_query, $_delegate; public function __construct($link, $query, $prepared) { //parent::__construct($link, $query); $this->_link = $link; $this->_query = $query; $this->_delegate = $prepared; } function bind_param($name, &$var) { return $this->_delegate->bind_param($name, $var); } function __call($name, $args) { //$rslt = call_user_func_array(array($this, 'parent::' . $name), $args); $rslt = call_user_func_array(array($this->_delegate, $name), $args); if (False === $rslt) { throw new DBException($this->_link->error, $this->errno); } return $rslt; } } The difficulty lies in calling methods such as bind_result on the wrapper. Constant-arity functions (e.g. bind_param) can be explicitly defined, allowing for pass-by-reference. bind_result, however, needs all arguments to be pass-by-reference. If you call bind_result on an instance of MySQLi_stmt_throwing as-is, the arguments are passed by value and the binding won't take. try { $id = Null; $stmt = $db->prepare('SELECT id FROM tbl WHERE ...'); $stmt->execute() $stmt->bind_result($id); // $id is still null at this point ... } catch (DBException $exc) { ... } Since the above classes are no longer in use, this question is merely a matter of curiosity. Alternate approaches to the wrapper classes are not relevant. Defining a method with a bunch of arguments taking Null default values is not correct (what if you define 20 arguments, but the function is called with 21?). Answers don't even need to be written in terms of MySQL_stmt_throwing; it exists simply to provide a concrete example.

  • How to maximize http.sys file upload performance

    - by anelson
    I'm building a tool that transfers very large streaming data sets (possibly on the order of terabytes in a single stream; routinely in the tens of gigabytes) from one server to another. The client portion of the tool will read blocks from the source disk, and send them over the network. The server side will read these blocks off the network and write them to a file on the server disk. Right now I'm trying to decide which transport to use. Options are raw TCP, and HTTP. I really, REALLY want to be able to use HTTP. The HttpListener (or WCF if I want to go that route) make it easy to plug in to the HTTP Server API (http.sys), and I can get things like authentication and SSL for free. The problem right now is performance. I wrote a simple test harness that sends 128K blocks of NULL bytes using the BeginWrite/EndWrite async I/O idiom, with async BeginRead/EndRead on the server side. I've modified this test harness so I can do this with either HTTP PUT operations via HttpWebRequest/HttpListener, or plain old socket writes using TcpClient/TcpListener. To rule out issues with network cards or network pathways, both the client and server are on one machine and communicate over localhost. On my 12-core Windows 2008 R2 test server, the TCP version of this test harness can push bytes at 450MB/s, with minimal CPU usage. On the same box, the HTTP version of the test harness runs between 130MB/s and 200MB/s depending upon how I tweak it. In both cases CPU usage is low, and the vast majority of what CPU usage there is is kernel time, so I'm pretty sure my usage of C# and the .NET runtime is not the bottleneck. The box has two 6-core Xeon X5650 processors, 24GB of single-ranked DDR3 RAM, and is used exclusively by me for my own performance testing. I already know about HTTP client tweaks like ServicePointManager.MaxServicePointIdleTime, ServicePointManager.DefaultConnectionLimit, ServicePointManager.Expect100Continue, and HttpWebRequest.AllowWriteStreamBuffering. Does anyone have any ideas for how I can get HTTP.sys performance beyond 200MB/s? Has anyone seen it perform this well on any environment?

  • Entity Framework in n-layered application - Lazy loading vs. Eager loading patterns

    - by Marconline
    Hi all. This questions doesn't let me sleep as it's since one year I'm trying to find a solution but... still nothing happened in my mind. Probably you can help me, because I think this is a very common issue. I've a n-layered application: presentation layer, business logic layer, model layer. Suppose for simplicity that my application contains, in the presentation layer, a form that allows a user to search for a customer. Now the user fills the filters through the UI and clicks a button. Something happens and the request arrives to presentation layer to a method like CustomerSearch(CustomerFilter myFilter). This business logic layer now keeps it simple: creates a query on the model and gets back results. Now the question: how do you face the problem of loading data? I mean business logic layer doesn't know that that particular method will be invoked just by that form. So I think that it doesn't know if the requesting form needs just the Customer objects back or the Customer objects with the linked Order entities. I try to explain better: our form just wants to list Customers searching by surname. It has nothing to do with orders. So the business logic query will be something like: (from c in ctx.CustomerSet where c.Name.Contains(strQry) select c).ToList(); now this is working correctly. Two days later your boss asks you to add a form that let you search for customers like the other and you need to show the total count of orders created by each customer. Now I'd like to reuse that query and add the piece of logic that attach (includes) orders and gets back that. How would you front this request? Here is the best (I think) idea I had since now. I'd like to hear from you: my CustomerSearch method in BLL doesn't create the query directly but passes through private extension methods that compose the ObjectQuery like: private ObjectQuery<Customer> SearchCustomers(this ObjectQuery<Customer> qry, CustomerFilter myFilter) and private ObjectQuery<Customer> IncludeOrders(this ObjectQuery<Customer> qry) but this doesn't convince me as it seems too complex. Thanks, Marco
