  • Wicket, Spring and Hibernate - Testing with Unitils - Error: Table not found in statement [select re

    - by John
    Hi there. I've been following a tutorial and a sample application, namely 5 Days of Wicket - Writing the tests: http://www.mysticcoders.com/blog/2009/03/10/5-days-of-wicket-writing-the-tests/ I've set up my own little project with a simple shoutbox that saves messages to a database. I then wanted to set up a couple of tests that would make sure that if a message is stored in the database, the retrieved object would contain the exact same data. Upon running mvn test all my tests fail. The exception has been pasted in the first code box underneath. I've noticed that even though my unitils.properties says to use the 'hdqldb'-dialect, this message is still output in the console window when starting the tests: INFO - Dialect - Using dialect: org.hibernate.dialect.PostgreSQLDialect. I've added the entire dump from the console as well at the bottom of this post (which goes on for miles and miles :-)). Upon running mvn test all my tests fail, and the exception is: Caused by: java.sql.SQLException: Table not found in statement [select relname from pg_class] at org.hsqldb.jdbc.Util.sqlException(Unknown Source) at org.hsqldb.jdbc.jdbcStatement.fetchResult(Unknown Source) at org.hsqldb.jdbc.jdbcStatement.executeQuery(Unknown Source) at org.apache.commons.dbcp.DelegatingStatement.executeQuery(DelegatingStatement.java:188) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.initSequences(DatabaseMetadata.java:151) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.(DatabaseMetadata.java:69) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.(DatabaseMetadata.java:62) at org.springframework.orm.hibernate3.LocalSessionFactoryBean$3.doInHibernate(LocalSessionFactoryBean.java:958) at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:419) ... 49 more I've set up my unitils.properties file like so: database.driverClassName=org.hsqldb.jdbcDriver database.url=jdbc:hsqldb:mem:PUBLIC database.userName=sa database.password= database.dialect=hsqldb database.schemaNames=PUBLIC My abstract IntegrationTest class: @SpringApplicationContext({"/com/upbeat/shoutbox/spring/applicationContext.xml", "applicationContext-test.xml"}) public abstract class AbstractIntegrationTest extends UnitilsJUnit4 { private ApplicationContext applicationContext; } applicationContext-test.xml: <?xml version="1.0" encoding="UTF-8"? <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd" <bean id="dataSource" class="org.unitils.database.UnitilsDataSourceFactoryBean"/ </beans and finally, one of the test classes: package com.upbeat.shoutbox.web; import org.apache.wicket.spring.injection.annot.test.AnnotApplicationContextMock; import org.apache.wicket.util.tester.WicketTester; import org.junit.Before; import org.junit.Test; import org.unitils.spring.annotation.SpringBeanByType; import com.upbeat.shoutbox.HomePage; import com.upbeat.shoutbox.integrations.AbstractIntegrationTest; import com.upbeat.shoutbox.persistence.ShoutItemDao; import com.upbeat.shoutbox.services.ShoutService; public class TestHomePage extends AbstractIntegrationTest { @SpringBeanByType private ShoutService svc; @SpringBeanByType private ShoutItemDao dao; protected WicketTester tester; @Before public void setUp() { AnnotApplicationContextMock appctx = new AnnotApplicationContextMock(); appctx.putBean("shoutItemDao", dao); appctx.putBean("shoutService", svc); tester = new WicketTester(); } @Test public void testRenderMyPage() { //start and render the test page tester.startPage(HomePage.class); //assert rendered page class tester.assertRenderedPage(HomePage.class); //assert rendered label component tester.assertLabel("message", "If you see this message wicket is properly configured and running"); } } Dump from console when running mvn test: [INFO] Scanning for projects...

  • Managing Dependency Hell with WiX and C#

    - by Tom the Junglist
    We are on the eve of product launch, and at the last minute I am being bombarded with crash reports that appear to be related to our installer, which is a WiX3 project with separate outputs for x86 and x64 builds. These have been an ongoing problem that I always thought were fixed, only to find out that they were still lurking. The product itself is a collection of binaries that communicate with each other via .Net remoting, including a Windows Service and a small COM component that is loaded as an addon in another app. The service runs as SYSTEM, the COM piece runs in a low-rights context, while the other pieces run in normal user contexts. Other pieces include an third-party COM object library DLL and a shared DLL with the .net Remoting interfaces. I've observed flat-out weird behavior with MSI, particularly on version upgrades. Between MS' anal strong-name implementation (specifically, the exact version check before loading a given assembly), a documented WiX/MSI bug that sees critical files erased on upgrades (essentially, if a file in the upgrade MSI has the same version number as the existing install, that file is deleted), and having to work around Wow64 virtualization (x86 MSI can only write to registry/HD locations via Wow64, yet x64 MSIs cannot run on x86 computers...), I am about ready to trash the whole thing and port it over to a different install system. What I am looking for on tips + tricks, techniques, or suggestions on how to properly do things so that I am not fighting with Windows Installer's twisted sense of logic. I am tired of fighting with WiX/MSI/Windows Installer. All it needs to do is place files and registry keys where I tell it to, upgrade them when appropriate, and don't delete anything until the user uninstalls. Instead, dependencies are deleted willy-nilly, bringing up a whole bunch of uncatchable exceptions (can't wrap a try{} block around function declarations) and GPF'ing the whole app. I am particularly interested in 'best practices' and examples regarding shared and dependency DLLs, and any tips on making sure if a file needs to go to GAC, that it actually goes to the GAC and stays there until it is appropriate to remove it. Thanks! Tom

  • C#: Streaming an Audio file from a Server to a Client

    - by Andreas Grech
    I am currently writing an application that will allow a user to install some form of an application (maybe a Windows Service) that will open a port on it's PC and given a particular destination on the hard disk, will then be able to stream mp3 files. I will then have another application that will connect to the server (being the user's pc) and be able to browse the hosted data by connecting to that PC (remotely ofcourse) given the port, and stream mp3 files from the server to the application I have found some tutorials online but most of them are about File Servers in C# and they download allow you to download a whole file. What I want is to stream an mp3 file so that it starts playing when a certain number of bytes are download (ie, whilst it is being buffered) How do I go about in accomplishing such a task? What I need to know specifically is how to write this application (that I will turn into a Windows Service later on) that will listen on a specified port a stream files, so that I can then access the files by something of the sort: http://<serverip>:65000/acdc/wholelottarosie.mp3 and hopefully be able to stream that file in a WPF MediaPlayer. [Update] I was following this tutorial about building a file server and sending the file from the server to the client. Is what I have to do something of the sort? [Update] Currently reading this post: Play Audio from a Stream using C# and I think it looks very promising as to how I can play streamed files; but I still don't know how I can actually stream the files from the server.

  • Reducing WPF binding boilerplate with styles - updating the bindings themselves via styling?

    - by Eamon Nerbonne
    I'm still learning the WPF ropes, so if the following question is trivial or my approach wrong-headed, please do speak up... I'm trying to reduce boilerplate and it sounds like styles are a common way to do so. In particular: I've got a bunch of fairly mundane data-entry fields. The controls for these fields have various properties I'd like to set based on the target of the binding - pretty normal stuff. However, I'd also like to set properties of the binding itself in the style to avoid repetitiveness. For example: <TextBox Style="{StaticResource myStyle}"> <TextBox.Text> <Binding Path="..." Source="..." ValidatesOnDataErrors="True" ValidatesOnExceptions="True" UpdateSourceTrigger="PropertyChanged"> </Binding> </TextBox.Text> </TextBox> Now, is there any way to use styling - or some other technique to write the previous example somewhat like this: <TextBox Style="{StaticResource myStyle}" Text="{Binding Source=... Path=...}/> That is, is there any way to set all bindings that match a particular selection (here, on controls with the myStyle style) to validate data and to use a particular update trigger? Is it possible to template or style bindings themselves? Clearly, the second syntax is much, much shorter and more readable, and I'd love to be able to get rid of other similar boilerplate to keep my UI code comprehensible to myself :-).

  • DRY Validation with MVC2

    - by Matthew
    Hi All, I'm trying to figure out how I can define validation rules for my domain objects in one single location within my application but have run in to a snag... Some background: My location has several parts: - Database - DAL - Business Logic Layer - SOAP API Layer - MVC website The MVC website accesses the database via the SOAP API, just as third parties would. We are using server and and client side validation on the MVC website as well as in the SOAP API Layer. To avoid having to manually write client side validation we are implementing strongly typed views in conjunction with the Html.TextBoxFor and Html.ValidationMessageFor HTML helpers, as shown in Step 3 here. We also create custom models for each form where one form takes input for multiple domain objects. This is where the problem begins, the HTML helpers read from the model for the data annotation validation attributes. In most cases our forms deal with multiple domain objects and you can't specify more than one type in the <%@Page ... Inherits="System.Web.Mvc.ViewPage" % page directive. So we are forced to create a custom model class, which would mean duplicating validation attributes from the domain objects on to the model class. I've spent quite some time looking for workarounds to this, such has referencing the same MetadataType from both the domain class and the custom MVC models, but that won't work for several reasons: You can only specify one MetadataType attribute per class, so its a problem if a model references multiple domain objects, each with their own metadata type. The data annotation validation code throws an exception if the model class doesn't contain a property that is specified in the referenced MetadataType which is a problem with the model only deals with a subset of the properties for a given domain object. I've looked at other solutions as well but to no avail. If anyone has any ideas on how to achieve a single source for validation logic that would work across MVC client and server side validation functionality and other locations (such as my SOAP API) I would love to hear it! Thanks in advance, Matthew

  • AWS Amazon EC2 - password-less SSH login for non-root users using PEM keypairs

    - by Mark White
    We've got a couple of clusters running on AWS (HAProxy/Solr, PGPool/PostgreSQL) and we've setup scripts to allow new slave instances to be auto-included into the clusters by updating their IPs to config files held on S3, then SSHing to the master instance to kick them to download the revised config and restart the service. It's all working nicely, but in testing we're using our master pem for SSH which means it needs to be stored on an instance. Not good. I want a non-root user that can use an AWS keypair who will have sudo access to run the download-config-and-restart scripts, but nothing else. rbash seems to be the way to go, but I understand this can be insecure unless setup correctly. So what security holes are there in this approach: New AWS keypair created for user.pem (not really called 'user') New user on instances: user Public key for user is in ~user/.ssh/authorized_keys (taken by creating new instance with user.pem, and copying it from /root/.ssh/authorized_keys) Private key for user is in ~user/.ssh/user.pem 'user' has login shell of /home/user/bin/rbash ~user/bin/ contains symbolic links to /bin/rbash and /usr/bin/sudo /etc/sudoers has entry "user ALL=(root) NOPASSWD: ~user/.bashrc sets PATH to /home/user/bin/ only ~user/.inputrc has 'set disable-completion on' to prevent double tabbing from 'sudo /' to find paths. ~user/ -R is owned by root with read-only access to user, except for ~user/.ssh which has write access for user (for writing known_hosts), and ~user/bin/* which are +x Inter-instance communication uses 'ssh -o StrictHostKeyChecking=no -i ~user/.ssh/user.pem user@ sudo ' Any thoughts would be welcome.

  • Applying Test Driven Development to a tightly coupled architecture

    - by Chris D
    Hi all, I've recently been studying TDD, attended a conference and have dabbled in few tests and already I'm 100% sold, I absolutely love it TDD. As a result I've raised this with my seniors and they are prepared to give it a chance, so they have tasked me with coming up with a way to implement TDD in the development of our enterprise product. The problem is our system has evolved since the days of VB6 to .NET and implements alot of legacy technology and some far from best practice development techniques i.e. alot of business logic in the ASP.NET code behind and client script. The largest problem however is how our classes are tightly coupled with database access; properties, methods, constructors - usually has some database access in some form or another. We use an in-house data access code generator tool that creates sqlDataAdapters that gives us all the database access we could ever want, which helps us develop extremely quickly, however, classes in our business layer are very tightly coupled to this data layer - we aren't even close to implementing some form of repository design. This and the issues above have created me all sorts of problems. I have tried to develop some unit tests for some existing classes I've already written but the tests take ALOT longer to run since db access is required, not to mention since we use the MS Enterprise Caching framework I am forced to fake a httpcontext for my tests to run successfully which isn't practical. Also, I can't see how to use TDD to drive the design of any new classes I write since they have to be soo tightly coupled to the database ... help! Because of the architecture of the system it appears I can't implement TDD without some real hack which in my eyes just defeats the aim of TDD and the huge benefits that come with. Does anyone have any suggestions how I could implement TDD with the constraints I'm bound too? or do I need to push the repository design pattern down my seniors throats and tell them we either change our architecture/development methodology or forget about TDD altogether? :) Thanks

  • Can I set a <probing> privatePath in ~/subdir/web.config without access to the root application .con

    - by Bago
    In ASP.NET, is it possible to set a path from a web.config in a subdir that is not setup as a virtual directory? In other words, can I reference a private assembly in the ~/subdir/bin folder? Take a look at my setup below, and let me know if I'm doing something wrong, please. Let me explain why I'm doing this: my page is setup in ~/subdir. I don't have write access to the root. I only have FTP access to the server (i.e., I am not an IIS admin and I can't login to the machine) I am trying to use FCKeditor in my subdir application Here is my folder structure: / | -subdir | | - Bin | | | *FredCK.FCKeditorV2.dll | | *Default.aspx | | *web.config Here is the <runtime> section of ~/subdir/web.config: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="subdir;subdir/bin" /> </dependentAssembly> </assemblyBinding> </runtime> I've tried all sorts of things to get to work. However, upon checking the Fusion logs, my subdir never shows up in the probing paths.

  • WPF derived ComboBox SelectedValuePath issue

    - by opedog
    In our application we have a very large set of data that acts as our data dictionary for ComboBox lists, etc. This data is staticly cached and keyed off of 2 variables, so I thought it wise to write a control that derived from ComboBox and exposed the 2 keys as DPs. When those 2 keys have proper values I set the ItemsSource of the ComboBox automatically from the data dictionary list it corresponds to. I also automatically set the SelectedValuePath and DisplayMemberPath to Code and Description, respectively. Here's how an example of how an item in the ItemsSource from the data dictionary list always looks: public class DataDictionaryItem { public string Code { get; set; } public string Description { get; set; } public string Code3 { get { return this.Get.Substring(0, 3); } } } The value of Code is always 4 bytes long, but sometimes I only need to bind 3 bytes of it. Hence, the Code3 property. Here's how the code looks inside my custom combobox to set the ItemsSource: private static void SetItemsSource(CustomComboBox combo) { if (string.IsNullOrEmpty(combo.Key1) || string.IsNullOrEmpty(combo.Key2)) { combo.ItemsSource = null; return; } List<DataDictionaryItem> list = GetDataDictionaryList(combo.Key1, combo.Key2); combo.ItemsSource = list; } Now, my problem is, when I change the SelectedValuePath in the XAML to Code3, it doesn't work. What I bind to SelectedValue still gets the full 4 character Code from DataDictionaryItem. I even tried rerunning SetItemsSource when the SelectedValuePath was changed and no dice. Can anyone see what I need to do to get my custom combobox to wake up and use the SelectedValuePath provided if it's overridden in the XAML? Tweaking the value in the property setter in my SelectedValue bound business object is not an option.

  • How to use Tor control protocol in C#?

    - by Ed
    I'm trying to send commands to the Tor control port programmatically to make it refresh the chain. I haven't been able to find any examples in C#, and my solution's not working. The request times out. I have the service running, and I can see it listening on the control port. public string Refresh() { TcpClient client = new TcpClient("localhost", 9051); string response = string.Empty; string authenticate = MakeTcpRequest("AUTHENTICATE", client); if (authenticate.Equals("250")) response = MakeTcpRequest("SIGNAL NEWNYM", client); client.Close(); return response; } public string MakeTcpRequest(string message, TcpClient client) { client.ReceiveTimeout = 20000; client.SendTimeout = 20000; string proxyResponse = string.Empty; try { // Send message StreamWriter streamWriter = new StreamWriter(client.GetStream()); streamWriter.Write(message); streamWriter.Flush(); // Read response StreamReader streamReader = new StreamReader(client.GetStream()); proxyResponse = streamReader.ReadToEnd(); } catch (Exception ex) { // Ignore } return proxyResponse; } Can anyone spot what I'm doing wrong?

  • What is wrong with this solution? (Perm-Missing-Elem codility test)

    - by user2956907
    I have started playing with codility and came across this problem: A zero-indexed array A consisting of N different integers is given. The array contains integers in the range [1..(N + 1)], which means that exactly one element is missing. Your goal is to find that missing element. Write a function: int solution(int A[], int N); that, given a zero-indexed array A, returns the value of the missing element. For example, given array A such that: A[0] = 2 A[1] = 3 A[2] = 1 A[3] = 5 the function should return 4, as it is the missing element. Assume that: N is an integer within the range [0..100,000]; the elements of A are all distinct; each element of array A is an integer within the range [1..(N + 1)]. Complexity: expected worst-case time complexity is O(N); expected worst-case space complexity is O(1), beyond input storage (not counting the storage required for input arguments). I have submitted the following solution (in PHP): function solution($A) { $nr = count($A); $totalSum = (($nr+1)*($nr+2))/2; $arrSum = array_sum($A); return ($totalSum-$arrSum); } which gave me a score of 66 of 100, because it was failing the test involving large arrays: "large_range range sequence, length = ~100,000" with the result: RUNTIME ERROR tested program terminated unexpectedly stdout: Invalid result type, int expected. I tested locally with an array of 100.000 elements, and it worked without any problems. So, what seems to be the problem with my code and what kind of test cases did codility use to return "Invalid result type, int expected"?

  • XNA vs SlimDX for offscreen renderer

    - by Groky
    Hello, I realise there are numerous questions on here asking about choosing between XNA and SlimDX, but these all relate to game programming. A little background: I have an application that renders scenes from XML descriptions. Currently I am using WPF 3D and this mostly works, except that WPF has no way to render scenes offscreen (i.e. on a server, without displaying them in a window), and also rendering to a bitmap causes WPF to fallback to software rendering. So I'm faced with having to write my own renderer. Here are the requirements: Mix of 3D and 2D elements. Relatively few elements per scene (tens of meshes, tens of 2D elements). Large scenes (up to 3000px square for print). Only a single frame will be rendered (i.e. FPS is not an issue). Opacity masks. Pixel shaders. Software fallback (servers may or may not have a decent gfx card). Possibility of being rendered offscreen. As you can see it's pretty simple stuff and WPF can manage it quite nicely except for the not-being-able-to-export-the-scene problem. In particular I don't need many of the things usually needed in game development. So bearing that in mind, would you choose XNA or SlimDX? The non-rendering portion of the code is already written in C#, so want to stick with that.

  • How to bulk insert a CSV file into SQLite C#

    - by Lirik
    I have seen similar questions (1, 2), but none of them discuss how to insert CSV files into SQLite. About the only thing I could think of doing is to use a CSVDataAdapter and fill the SQLiteDataSet, then use the SQLiteDataSet to update the tables in the database: The only DataAdapter for CSV files I found is not actually available: CSVDataAdapter CSVda = new CSVDataAdapter(@"c:\MyFile.csv"); CSVda.HasHeaderRow = true; DataSet ds = new DataSet(); // <-- Use an SQLiteDataSet instead CSVda.Fill(ds); To write to a CSV file: CSVDataAdapter CSVda = new CSVDataAdapter(@"c:\MyFile.csv"); bool InclHeader = true; CSVda.Update(MyDataSet,"MyTable",InclHeader); I found the above code @ http://devintelligence.com/2005/02/dataadapter-for-csv-files/ The CSVDataAdapter was supposed to come with OpenNetCF's SDF, but it doesn't seem to be available anymore. Does anybody know where I can get a CSVDataAdapter? Perhaps somebody knows the much simpler thing: how to do bulk inserts of CSV files into SQLite... your help would be greatly appreciated!

  • Open a URL with parameters using selenium.open()

    - by gagneet
    I am using selenium.open(), to open a URL, which prints the cookie output to the browser window: String cookiestr = "http://my.server.com/cookie?out=text"; selenium.open( cookiestr ); The problem is that, it opens a "Save As..." popup, to save the file named "cookie". When I open the same URL in my browser directly, it displays text in the browser window. I want to capture the body text shown, when I open the URL, but am unable to do so. Is there any other command available which I can use to do this? BufferedWriter outputfile = null; String bodytext = selenium.getBodyText(); System.out.println("Body Text :" + bodytext); Integer I = new Integer(i); filename = "C:\\cookies\\" + I.toString() + ".txt"; outputfile = new BufferedWriter(new FileWriter( filename )); outputfile.write( bodytext ); outputfile.newLine(); i++;

  • Partial template specialization of free functions - best practices

    - by Poita_
    As most C++ programmers should know, partial template specialization of free functions is disallowed. For example, the following is illegal C++: template <class T, int N> T mul(const T& x) { return x * N; } template <class T> T mul<T, 0>(const T& x) { return T(0); } // error: function template partial specialization ‘mul<T, 0>’ is not allowed However, partial template specialization of classes/structs is allowed, and can be exploited to mimic the functionality of partial template specialization of free functions. For example, the target objective in the last example can be achieved by using: template <class T, int N> struct mul_impl { static T fun(const T& x) { return x * N; } }; template <class T> struct mul_impl<T, 0> { static T fun(const T& x) { return T(0); } }; template <class T, int N> T mul(const T& x) { return mul_impl<T, N>::fun(x); } It's more bulky and less concise, but it gets the job done -- and as far as users of mul are concerned, they get the desired partial specialization. My questions is: when writing templated free functions (that are intended to be used by others), should you automatically delegate the implementation to a static method function of a class, so that users of your library may implement partial specializations at will, or do you just write the templated function the normal way, and live with the fact that people won't be able to specialize them?

  • Need help on HL7

    - by rohit
    Hi All, I need all your help in guiding me with working on HL7 Interface Integration which I am to work on between two disperate clinical applications. Its something like this ,let me explain my query with an example. "We have Epic system that places orders(lab,medications..etc) presently.Now,next these lab orders are to result in another Cerner application. For this,there has to be a INTERFACE ENGINE which has to read the HL7 messages coming from the EPIC system and translate them to proper messages for the Cerner SYSTEM and then write into their database. So,could you please explain me with an example interface engine which reads the HL-7 messages first and translates them to Cerner application format. How will i implement a Interface Engine here which would read the EPIC data? What steps are involved? An example would be best. Mainly,orders are first placed in EPIC and is to resulted in Cerner applications. **PLEASE PLEASE help me with understanding the process,and how to do interface intregation with an Interface Engine? Thanks Rohit

  • WPF: Is it possible to add or modify bindings via styles or something similar?

    - by Eamon Nerbonne
    I'm still learning the WPF ropes, so if the following question is trivial or my approach wrong-headed, please do speak up... I'm trying to reduce boilerplate and it sounds like styles are a common way to do so. In particular: I've got a bunch of fairly mundane data-entry fields. The controls for these fields have various properties I'd like to set based on the target of the binding - pretty normal stuff. However, I'd also like to set properties of the binding itself in the style to avoid repetitiveness. For example: <TextBox Style="{StaticResource myStyle}"> <TextBox.Text> <Binding Path="..." Source="..." ValidatesOnDataErrors="True" ValidatesOnExceptions="True" UpdateSourceTrigger="PropertyChanged"> </Binding> </TextBox.Text> </TextBox> Now, is there any way to use styling - or some other technique to write the previous example somewhat like this: <TextBox Style="{StaticResource myStyle}" Text="{Binding Source=... Path=...}/> That is, is there any way to set all bindings that match a particular selection (here, on controls with the myStyle style) to validate data and to use a particular update trigger? Is it possible to template or style bindings themselves? Alternatively, is it possible to add the binding in the style itself? Clearly, the second syntax is much, much shorter and more readable, and I'd love to be able to get rid of other similar boilerplate to keep my UI code comprehensible to myself :-).

  • IIS HTTP Error 403.1 - Forbidden: Execute access is denied

    - by coxymla
    I have a ASP.NET 1.1 application running on IIS 6 / Windows Server 2003. It's our application, but we're trying to specifically replicate a customer's installation so the app folder has been copied entirely from their production server onto our test machine, and then we've created the Virtual Directory and Web Application for IIS manually. The problem I have is that when we access the app, we get the standard IIS security error message: The page cannot be displayed You have attempted to execute a CGI, ISAPI, or other executable program from a directory that does not allow programs to be executed. -------------------------------------------------------------------------------- Please try the following: •Contact the Web site administrator if you believe this directory should allow execute access. HTTP Error 403.1 - Forbidden: Execute access is denied. Internet Information Services (IIS) Now this is pretty standard, except as far as I can see it's not anything so simple. I have checked: IIS user has read access to the directory IIS user and Network Service users have read/write access to the Temporary ASP.NET Files folder Virtual directory is set to the correct version of ASP.NET ASP.NET 1.1 Web Service Extension is allowed Virtual directory has the correct mappings of file extensions and all verbs to the aspnet 1.1 DLL Virtual directory properties allow Scripts and Executables to be run Anonymous access is turned on and the username and password is correct What am I missing?

  • Logging Into a site that uses Live.com authentication with C#

    - by Josh
    I've been trying to automate a log in to a website I frequent, www.bungie.net. The site is associated with Microsoft and Xbox Live, and as such makes uses of the Windows Live ID API when people log in to their site. I am relatively new to creating web spiders/robots, and I worry that I'm misunderstanding some of the most basic concepts. I've simulated logins to other sites such as Facebook and Gmail, but live.com has given me nothing but trouble. Anyways, I've been using Wireshark and the Firefox addon Tamper Data to try and figure out what I need to post, and what cookies I need to include with my requests. As far as I know these are the steps one must follow to log in to this site. 1. Visit https: //login.live.com/login.srf?wa=wsignin1.0&rpsnv=11&ct=1268167141&rver=5.5.4177.0&wp=LBI&wreply=http:%2F%2Fwww.bungie.net%2FDefault.aspx&id=42917 2. Recieve the cookies MSPRequ and MSPOK. 3. Post the values from the form ID "PPSX", the values from the form ID "PPFT", your username, your password all to a changing URL similar to: https: //login.live.com/ppsecure/post.srf?wa=wsignin1.0&rpsnv=11&ct= (there are a few numbers that change at the end of that URL) 4. Live.com returns the user a page with more hidden forms to post. The client then posts the values from the form "ANON", the value from the form "ANONExp" and the values from the form "t" to the URL: http ://www.bung ie.net/Default.aspx?wa=wsignin1.0 5. After posting that data, the user is returned a variety of cookies the most important of which is "BNGAuth" which is the log in cookie for the site. Where I am having trouble is on fifth step, but that doesn't neccesarily mean I've done all the other steps correctly. I post the data from "ANON", "ANONExp" and "t" but instead of being returned a BNGAuth cookie, I'm returned a cookie named "RSPMaybe" and redirected to the home page. When I review the Wireshark log, I noticed something that instantly stood out to me as different between the log when I logged in with Firefox and when my program ran. It could be nothing but I'll include the picture here for you to review. I'm being returned an HTTP packet from the site before I post the data in the fourth step. I'm not sure how this is happening, but it must be a side effect from something I'm doing wrong in the HTTPS steps. ![alt text][1] http://img391.imageshack.us/img391/6049/31394881.gif using System; using System.Collections.Generic;

  • NHibernate Query across multiple tables

    - by Dai Bok
    I am using NHibernate, and am trying to figure out how to write a query, that searchs all the names of my entities, and lists the results. As a simple example, I have the following objects; public class Cat { public string name {get; set;} } public class Dog { public string name {get; set;} } public class Owner { public string firstname {get; set;} public string lastname {get; set;} } Eventaully I want to create a query , say for example, which and returns all the pet owners with an name containing "ted", OR pets with a name containing "ted". Here is an example of the SQL I want to execute: SELECT TOP 10 d.*, c.*, o.* FROM owners AS o INNER JOIN dogs AS d ON o.id = d.ownerId INNER JOIN cats AS c ON o.id = c.ownerId WHERE o.lastname like '%ted%' OR o.firstname like '%ted%' OR c.name like '%ted%' OR d.name like '%ted%' When I do it using Criteria like this: var criteria = session.CreateCriteria<Owner>() .Add( Restrictions.Disjunction() .Add(Restrictions.Like("FirstName", keyword, MatchMode.Anywhere)) .Add(Restrictions.Like("LastName", keyword, MatchMode.Anywhere)) ) .CreateCriteria("Dog").Add(Restrictions.Like("Name", keyword, MatchMode.Anywhere)) .CreateCriteria("Cat").Add(Restrictions.Like("Name", keyword, MatchMode.Anywhere)); return criteria.List<Owner>(); The following query is generated: SELECT TOP 10 d.*, c.*, o.* FROM owners AS o INNER JOIN dogs AS d ON o.id = d.ownerId INNER JOIN cats AS c ON o.id = c.ownerId WHERE o.lastname like '%ted%' OR o.firstname like '%ted%' AND d.name like '%ted%' AND c.name like '%ted%' How can I adjust my query so that the .CreateCriteria("Dog") and .CreateCriteria("Cat") generate an OR instead of the AND? thanks for your help.

    I'm using RabbitMQ on RHEL 5.3 using the Java client. I have 2 nodes (machines). Node1 is consuming messages from a queue on Node2 using the Java helper class QueueingConsumer. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(); ... Process message - delivery.getBody() } If the interface is brought down on Node1 or Node2 (e.g. ifconfig eth1 down), the client (above) never knows the network isn't there anymore. Does RabbitMQ provide some type of configuration on the Java client that can be used to determine if the connection has gone away. Shutting down the RabbitMQ server on Node2 will trigger a ShutdownSignalException, which can be caught and the app can go into a reconnect loop. But bringing down the interface doesn't cause any type of exception to happen, so the code will be waiting forever on consumer.nextDelivery(). I've also tried using the timeout version of this call. e.g. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); int timeout_ms = 30000; while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(timeout_ms); if (delivery == null) { if (channel.isOpen() == false) // Seems to always return true { throw new ShutdownSignalException(); } } else { ... Process message - delivery.getBody() } } but appears that this always returns true (even though the interface is down). I assume registering for the ShutdownListener on the connection will yield the same results, but haven't tried that yet. Is there a way to configure some sort of heartbeat, or do you just have to write custom lease logic (e.g. "I'm here now") in order to get this to work?

  • C#: Struct Constructor: "fields must be fully assigned before control is returned to the caller."

    - by Rosarch
    Here is a struct I am trying to write: public struct AttackTraits { public AttackTraits(double probability, int damage, float distance) { Probability = probability; Distance = distance; Damage = damage; } private double probability; public double Probability { get { return probability; } set { if (value > 1 || value < 0) { throw new ArgumentOutOfRangeException("Probability values must be in the range [0, 1]"); } probability = value; } } public int Damage { get; set; } public float Distance { get; set; } } This results in the following compilation errors: The 'this' object cannot be used before all of its fields are assigned to Field 'AttackTraits.probability' must be fully assigned before control is returned to the caller Backing field for automatically implemented property 'AttackTraits.Damage' must be fully assigned before control is returned to the caller. Consider calling the default constructor from a constructor initializer. Backing field for automatically implemented property 'AttackTraits.Distance' must be fully assigned before control is returned to the caller. Consider calling the default constructor from a constructor initializer. What am I doing wrong?
