• Integration test failing through NUnit Gui/Console, but passes through TestDriven in IDE

  - by Cliff

  I am using NHibernate against an Oracle database with the NHibernate.Driver.OracleDataClientDriver driver class. I have an integration test that pulls back expected data properly when executed through the IDE using TestDriven.net. However, when I run the unit test through the NUnit GUI or Console, NHibernate throws an exception saying it cannot find the Oracle.DataAccess assembly. Obviously, this prevents me from running my integration tests as part of my CI process. NHibernate.HibernateException : The IDbCommand and IDbConnection implementation in the assembly Oracle.DataAccess could not be found. Ensure that the assembly Oracle.DataAccess is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly.* I have tried making the assembly available in two ways, by copying it into the bin\debug folder and by adding the element in the config file. Again, both methods work when executing through TestDriven in the IDE. Neither work when executing through NUnit GUI/Console. The NUnit Gui log displays the following message. 21:42:26,377 ERROR [TestRunnerThread] ReflectHelper [(null)]- Could not load type Oracle.DataAccess.Client.OracleConnection, Oracle.DataAccess. System.BadImageFormatException: Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.20, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies.

• Castle ActiveRecord "Could not compile the mapping document: (string)"

  - by Nick

  Hi I am having getting an exception when trying to initialize ActiveRecord and I cannot figure out what I am missing. I am trying to convince the company I work for to use Castle ActiveRecord and it won't look good if I can't demonstrate how it works. I have work on projects before with Castle ActiveRecord and I had never experience this problem before.

• How do I use VS2010 One-Click Publish (MsDeploy) to deploy remotely from the command line?

  - by David

  On the remote web server I have installed the remote service http://x.x.x.x/MsDeployAgentService. If I use the Web Application Project's Publish command in VS2010 I can successfully publish to this remote web server and update a specific IIS website. What I want to do now is execute this capability from the command line. I am guessing it is two steps. First build the web application project using the relevant build configuration: msbuild "C:\MyApplication\MyWebApplication.csproj" /T:Package /P:Configuration=Release Then issue the MsDeploy command to have it publish/sync with the remove IIS server: msdeploy -verb:sync -source:package="C:\MyApplication\obj\Release\Package\MyWebApplication.zip" -dest:contentPath="My Production Website", computerName=http://x.x.x.x/MsDeployAgentService, username=adminuser,password=adminpassword Unfortunately I get an the error: Error: (10/05/2010 3:52:02 PM) An error occurred when the request was processed on the remote computer. Error: Source (sitemanifest) and destination (contentPath) are not compatible for the given operation. Error count: 1. I have tried a number of different combinations for destination provider but no joy :( Has anyone managed to replicate VS2010 Web Application Project "One Click" Publish from the command line?

On debug mode, I see that openNodes is accessible and contains the open nodes, as expected. Doing tmp:Object = parentComponent.dataGrid.dataProvider.openNodes works, but not with ObjectUtil. (parentComponent is the reference to the component which contains the DG).

• How to prevent duplicate records being inserted with SqlBulkCopy when there is no primary key

  - by kscott

  I receive a daily XML file that contains thousands of records, each being a business transaction that I need to store in an internal database for use in reporting and billing. I was under the impression that each day's file contained only unique records, but have discovered that my definition of unique is not exactly the same as the provider's. The current application that imports this data is a C#.Net 3.5 console application, it does so using SqlBulkCopy into a MS SQL Server 2008 database table where the columns exactly match the structure of the XML records. Each record has just over 100 fields, and there is no natural key in the data, or rather the fields I can come up with making sense as a composite key end up also having to allow nulls. Currently the table has several indexes, but no primary key. Basically the entire row needs to be unique. If one field is different, it is valid enough to be inserted. I looked at creating an MD5 hash of the entire row, inserting that into the database and using a constraint to prevent SqlBulkCopy from inserting the row,but I don't see how to get the MD5 Hash into the BulkCopy operation and I'm not sure if the whole operation would fail and roll back if any one record failed, or if it would continue. The file contains a very large number of records, going row by row in the XML, querying the database for a record that matches all fields, and then deciding to insert is really the only way I can see being able to do this. I was just hoping not to have to rewrite the application entirely, and the bulk copy operation is so much faster. Does anyone know of a way to use SqlBulkCopy while preventing duplicate rows, without a primary key? Or any suggestion for a different way to do this?

• Problem with Remember Me Service in Spring Security

  - by Gearóid

  Hi, I'm trying to implement a "remember me" functionality in my website using Spring. The cookie and entry in the persistent_logins table are getting created correctly. Additionally, I can see that the correct user is being restored as the username is displayed at the top of the page. However, once I try to access any information for this user when they return after they were "remembered", I get a NullPointerException. It looks as though the user isn't being set in the session again. My applicationContext-security.xml contains the following: <remember-me data-source-ref="dataSource" user-service-ref="userService"/> ... <authentication-provider user-service-ref="userService" /> <jdbc-user-service id="userService" data-source-ref="dataSource" role-prefix="ROLE_" users-by-username-query="select email as username, password, 1 as ENABLED from user where email=?" authorities-by-username-query="select user.id as id, upper(role.name) as authority from user, role, users_roles where users_roles.user_fk=id and users_roles.role_fk=role.name and user.email=?"/> I thought it may have had something to do with users-by-username query but surely login wouldn't work correctly if this query was incorrect? Any help on this would be greatly appreciated. Thanks, gearoid.

• Newbie, deciding Python or Erlang

  - by Joe

  Hi Guys, I'm a Administrator (unix, Linux and some windows apps such as Exchange) by experience and have never worked on any programming language besides C# and scripting on Bash and lately on powershell. I'm starting out as a service provider and using multiple network/server monitoring tools based on open source (nagios, opennms etc) in order to monitor them. At this moment, being inspired by a design that I came up with, to do more than what is available with the open source at this time, I would like to start programming and test some of these ideas. The requirement is that a server software that captures a stream of data and store them in a database(CouchDB or MongoDB preferably) and the client side (agent installed on a server) would be sending this stream of data on a schedule of every 10 minutes or so. For these two core ideas, I have been reading about Python and Erlang besides ruby. I do plan to use either Amazon or Rackspace where the server platform would run. This gives me the scalability needed when we have more customers with many servers. For that reason alone, I thought Erlang was a better fit(I could be totally wrong, new to this game) and I understand that Erlang has limited support in some ways compared to Ruby or Python. But also I'm totally new to the programming realm of things and any advise would be appreciated grately. Jo

• Web-based clients vs thick/rich clients?

  - by rudolfv

  My company is a software solutions provider to a major telecommunications company. The environment is currently IBM WebSphere-based with front-end IBM Portal servers talking to a cluster of back-end WebSphere Application Servers providing EJB services. Some of the portlets use our own home-grown MVC-pattern and some are written in JSF. Recently we did a proof-of-concept rich/thick-client application that communicates directly with the EJB's on the back-end servers. It was written in NetBeans Platform and uses the WebSphere application client library to establish communication with the EJB's. The really painful bit was getting the client to use secure JAAS/SSL communications. But, after that was resolved, we've found that the rich client has a number of advantages over the web-based portal client applications we've become accustomed to: Enormous performance advantage (CORBA vs. HTTP, cut out the Portal Server middle man) Development is simplified and faster due to use of NetBeans' visual designer and Swing's generally robust architecture The debug cycle is shortened by not having to deploy your client application to a test server No mishmash of technologies as with web-based development (Struts, JSF, JQuery, HTML, JSTL etc., etc.) After enduring the pain of web-based development (even JSF) for a while now, I've come to the following conclusion: Rich clients aren't right for every situation, but when you're developing an in-house intranet-based solution, then you'd be crazy not to consider NetBeans Platform or Eclipse RCP. Any comments/experiences with rich clients vs. web clients?

• Single Sign On for Web Application and Application in Virtual Directory

  - by Stefan

  To enable single sign-on for a web application and a web application in a virtual directory, I set the machinekey in both apps to the same: <machineKey validationKey="xxx" decryptionKey="yy" validation="SHA1" /> The single sign on works just fine, but existing users can't sign in any more; their passwords are rejected. The machinekey used to be this in the parent application: <machineKey validationKey="xxx,IsolateApps" decryptionKey="yy,IsolateApps" validation="SHA1" /> I tried other ways to make single sign on work, but it just won't as long as the keys contain "IsolateApps". What am I missing? I should add that the in the membership provider, passwordFormat is set to "Encrypted". So I assume the password was encrypted using the key that contained "IsolateApps" and now when it tries to validate the password it's using the key without the "IsolateApps". Still not sure how to solve that problem. Is there maybe a way that I can set the encryption keys for the password separately from the one that is used for the authentication cookie?

• How to access/use custom attribute in spring security based CAS client

  - by Bill Li

  I need send certain attributes(say, human readable user name) from server to client after a successful authentication. Server part was done. Now attribute was sent to client. From log, I can see: 2010-03-28 23:48:56,669 DEBUG Cas20ServiceTicketValidator:185 - Server response: [email protected] <cas:proxyGrantingTicket>PGTIOU-1-QZgcN61oAZcunsC9aKxj-cas</cas:proxyGrantingTicket> <cas:attributes> <cas:FullName>Test account 1</cas:FullName> </cas:attributes> </cas:authenticationSuccess> </cas:serviceResponse> Yet, I don't know how to access the attribute in client(I am using Spring security 2.0.5). In authenticationProvider, a userDetailsService is configured to read db for authenticated principal. <bean id="casAuthenticationProvider" class="org.springframework.security.providers.cas.CasAuthenticationProvider"> <sec:custom-authentication-provider /> <property name="userDetailsService" ref="clerkManager"/> <!-- other stuff goes here --> </bean> Now in my controller, I can easily do this: Clerk currentClerk = (Clerk)SecurityContextHolder.getContext().getAuthentication().getPrincipal(); Ideally, I can fill the attribute to this Clerk object as another property in some way. How to do this? Or what is recommended approach to share attributes across all apps under CAS's centralized nature?

• Start or ensure that Delayed Job runs when an application/server restarts.

  - by btelles

  Hi there, We have to use delayed_job (or some other background-job processor) to run jobs in the background, but we're not allowed to change the boot scripts/boot-levels on the server. This means that the daemon is not guaranteed to remain available if the provider restarts the server (since the daemon would have been started by a capistrano recipe that is only run once per deployment). Currently, the best way I can think of to ensure the delayed_job daemon is always running, is to add an initializer to our Rails application that checks if the daemon is running. If it's not running, then the initializer starts the daemon, otherwise, it just leaves it be. The question, therefore, is how do we detect that the Delayed_Job daemon is running from inside a script? (We should be able to start up a daemon fairly easily, bit I don't know how to detect if one is already active). Anyone have any ideas? Regards, Bernie Based on the answer below, this is what I came up with. Just put it in config/initializers and you're all set: #config/initializers/delayed_job.rb DELAYED_JOB_PID_PATH = "#{Rails.root}/tmp/pids/delayed_job.pid" def start_delayed_job Thread.new do `ruby script/delayed_job start` end end def process_is_dead? begin pid = File.read(DELAYED_JOB_PID_PATH).strip Process.kill(0, pid.to_i) false rescue true end end if !File.exist?(DELAYED_JOB_PID_PATH) && process_is_dead? start_delayed_job end

• Using db4o with multiple application instances under medium trust

  - by Anders Fjeldstad

  I recently stumbled over the object database engine db4o which I think looks really interesting. I would like to use it in an ASP.NET MVC application that will be deployed to a shared hosting environment under medium trust. Because of the trust level, I'm restricted to using db4o in embedded/in-process mode. That in itself should be no problem, but the hosting provider also transparently runs each web application in multiple (load-balanced) server instances with shared storage, which I would say is normally a very nice feature for a $10/month hoster. However, since an instance of a db4o server with write access (whether in-process or networked) locks the underlying database file, having multiple instances of the application using the same file won't work (or at least I can't see how it would). So the question is: is it possible to use db4o in this specific environment? I have considered letting each application have its own database which is synchronized with a master database using replication (dRS), but that approach will most likely end up with very frequent bi-directional replication (read master changes at beginning of each request, write to master after each change) which I don't think will be very efficient. Summary of the web application/environment characteristics: Read-intensive (but not entirely read-only) Some delay (a few seconds) is acceptible between the time that a change is made and the time when the change shows up in all the application instances' data Must run in medium trust No guarantee that the load-balancer uses "sticky sessions" All suggestions are much appreciated!

• Accessing Yahoo realtime stock quotes

  - by DVK

  There's a fairly easy way of retrieving 15-minute delayed quotes off of Yahoo! Finance web site ("quotes.csv" API). However, so far I was unable to find any info on how to access real-time quotes. The hang-ups with real-time quotes are: Only available to logged-in user No API Non-obvious how to scrape the info - I'm somewhat convinced they are placed on the page by some weird Ajax call. So I was wondering if anyone had managed to develop a publically available solution to retrieve real-time quotes for a stock from Yahoo! Finance. Notes: Implementation language/framework need is flexible but Perl or Excel is highly preferred. Assume that security is not an issue - I'm willing to supply yahoo userid and pasword, even in cleartext. I'm not 100% hung up on Yahoo - they are merely the only provider of free realtime stock quotes I'm familiar with. if the same thing can be done with Google Finance, I'd be just as happy. This is for a personal project, so scalability/fault tolerance/etc... are not important. I'm looking for a "do the whole retrieval" library ideally, but if I'm pointed to partial solutions (e.g. how to retrieve info from Yahoo's user-logged-in pages; how to scrape realtime quotes from Yahoo's page) I can fill in the blanks. I saw Finance::YahooQuote but it does not seem to allow you to supply log-in information and appears to use the lagging quotes.csv API Thanks!

• Dynamics CRM Customer Portal Accelerator Installation

  - by saturdayplace

  (I've posted this question on the codeplex forums too, but have yet to get a response) I've got an on-premise installation of CRM and I'm trying to hook the portal to it. My connection string in web.config: <connectionStrings> <add name="Xrm" connectionString="Authentication Type=AD; Server=http://myserver:myport/MyOrgName; User ID=mydomain\crmwebuser; Password=thepassword" /> </connectionStrings> And my membership provider: <membership defaultProvider="CustomCRMProvider"> <providers> <add connectionStringName="Xrm" applicationName="/" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" minRequiredPasswordLength="1" minRequiredNonalphanumericCharacters="0" name="CustomCRMProvider" type="System.Web.Security.SqlMembershipProvider" /> </providers> </membership> Now, I'm super new to MS style web development, so please help me if I'm missing something. In Visual Studio 2010, when I go to Project ASP.NET Configuration it launches the Web Site Administration Tool. When I click the Security Tab there, I get the following error: There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: An error occurred while attempting to initialize a System.Data.SqlClient.SqlConnection object. The value that was provided for the connection string may be wrong, or it may contain an invalid syntax. Parameter name: connectionString I can't see what I'm doing wrong here. Does the user mydomain\crmwebuser need certain permissions in the SQL database, or somewhere else? edit: On the home page of the Web Site Administration Tool, I have the following: **Application**:/ **Current User Name**:MACHINENAME\USERACCOUNT Which is obviously a different set of credentials than mydomain\crmwebuser. Is this part of the problem?

• How do you host multiple public facing websites on a VPS?

  - by Petras

  We host about 30 websites using typical shared hosting plans using ASP.NET and SQL 2000/2005/2008. I am now wondering about hosting all of these websites using our own virtual private server such as http://www.crystaltech.com/vps.aspx This is clearly cheaper but comes with a lot of questions I need answers to: Is the risk of having to keep this VPS server up and running worth it? Until now, the host provider has managed the server and we have not had to worry about crashes, downtime, software patches etc. We are not server administrators, we are programmers, so this is not really our expertise. On the other hand, it may not be hard to learn. When we make a website live, we log in to a domain management control panel and change the primary and secondary name servers to point to our shared web host: Eg ns1.sharedwebhost.com and ns2.sharedwebhost.com These name servers are going to have to change when we have a VPS. I don’t understand anything about how to set this up. Is there some useful info anyone could direct me to? Or is there software we need to install to make the primary and secondary name servers work on our VPS? The control panel we have for shared hosting comes with DNS management like this: What software would I need to install to create this for each site we host at a VPS? The control panel we have for shared hosting also comes with a POP email interface that allows email addresses to be added easily: Is this something that can be easily set up at a VPS so clients can manage their own email addresses? Is there software we need to install to make this work?

• IIS 7 can't connect to SQLServer 2008

  - by Nicolas Cadilhac

  Sorry if this is the most seen question on the web, but this is my turn. I am trying to publish my asp.net mvc app on IIS 7 under MS Sql Server 2008. I am on a Windows Server 2008 virtual machine. I get the following classical error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Under SQLServer, Allow remote connections is checked. My connection string is: Data Source=.\MSSQLSERVER;Initial Catalog=mydbname;User Id=sa;Password=mypassword I also tried with no username/password and "Integrated Security=true". There is only one instance of SQLServer installed. I tried to access my web page locally and remotely. There is no active firewall on the virtual machine. Thx for your help.

• LINQ-to-SQL: Could not find key member 'x' of key 'x' on type 'y'

  - by Austin Hyde

  I am trying to connect my application to a SQLite database with LINQ-to-SQL, and so far everything has worked fine. The only hitch was that the SQLite provider I am using does not support code generation (unless I was doing something wrong), so I manually coded the 4 tables in the DB. The solution builds properly, but will not run, giving me the error message Could not find key member 'ItemType_Id' of key 'ItemType_Id' on type 'Item'. The key may be wrong or the field or property on 'Item' has changed names. I have checked and double checked spellings and field names on the database and in the attribute mappings, but could not find any problems. The SQL for the table looks like this: CREATE TABLE [Items] ( [Id] integer PRIMARY KEY AUTOINCREMENT NOT NULL, [Name] text NOT NULL, [ItemType_Id] integer NOT NULL ); And my mapping code: [Table(Name="Items")] class Item { // [snip] [Column(Name = "Id", IsPrimaryKey=true, IsDbGenerated=true)] public int Id { get; set; } // [snip] [Column(Name="ItemType_Id")] public int ItemTypeId { get; set; } [Association(Storage = "_itemType", ThisKey = "ItemType_Id")] public ItemType ItemType { get { return _itemType.Entity; } set { _itemType.Entity = value; } } private EntityRef<ItemType> _itemType; // [snip] } This is really my first excursion into LINQ-to-SQL, and am learning as I go, but I cannot seem to get past this seeming simple problem. Why cannot LINQ see my association?

• Milliseconds in DateTime.Now on .NET Compact Framework always zero? [SOLVED]

  - by Marcel

  Hi all, i want to have a time stamp for logs on a Windows Mobile project. The accuracy must be in the range a hundred milliseconds at least. However my call to DateTime.Now returns a DateTime object with the Millisecond property set to zero. Also the Ticks property is rounded accordingly. How to get better time accuracy? Remember, that my code runs on on the Compact Framework, version 3.5. I use a HTC touch Pro 2 device. Based on the answer from MusiGenesis i have created the following class which solved this problem: /// <summary> /// A more precisely implementation of some DateTime properties on mobile devices. /// </summary> /// <devdoc>Tested on a HTC Touch Pro2.</devdoc> public static class DateTimePrecisely { /// <summary> /// Remembers the start time when this model was created. /// </summary> private static DateTime _start = DateTime.Now; /// <summary> /// Remembers the system uptime ticks when this model was created. This /// serves as a more precise time provider as DateTime.Now can do. /// </summary> private static int _startTick = Environment.TickCount; /// <summary> /// Gets a DateTime object that is set exactly to the current date and time on this computer, expressed as the local time. /// </summary> /// <returns></returns> public static DateTime Now { get { return _start.AddMilliseconds(Environment.TickCount - _startTick); } } }

• The Date type and the Android database

  - by cdonner

  I understand that SQLite stores dates as long integers. When I read rows into a cursor using the standard method (i.e. using the query() method that reads data into a cursor), the result is a date string that includes the time. If I want a different format, I have to parse the string back into a date - possible, but a bit backwards. By using a ViewBinder (as suggested in this question), I can pretty much do anything I want, but the date is already a string at the time the method executes. The accepted answer to the above question also suggests that storing dates as longs would help avoid this problem. I don't want to do that, just in case I want to interpret my data with something else than this application. Maybe I want to expose it via a provider. Is there a way to handle this in the database adapter instead, i.e. controlling the date format that the cursor contains, so that I don't have to change the schema, and don't have to parse the default output back into a Date type?

• Gmail IMAP OAuth for desktop clients

  - by Sabya

  Recently Google announced that they are supporting OAUth for Gmail IMAP/SMTP. I browsed through their multiple documentations, but still I am confused about if they support OAuth for installed applications. 1. In this documentation they say: Note: Though the OAuth protocol supports the desktop/installed application use case, Google only supports OAuth for web applications. But they also have a document for OAuth for installed applications. 2. When I read the OAuth specification pointed by them, it says (in section 11.7): In many applications, the Consumer application will be under the control of potentially untrusted parties. For example, if the Consumer is a freely available desktop application, an attacker may be able to download a copy for analysis. In such cases, attackers will be able to recover the Consumer Secret used to authenticate the Consumer to the Service Provider. Also I think the disclaimer in point 1 above is about Google Data APIs, and surely IMAP/SMTP is not a part of them. I understand that for installed applications I can have a setup like: Have a small web-app at say example.com for my application. This web-app talks to Google gets the access token. The installed application talks to example.com only to get the access token. Installed application then talks to Google with the access token. I am now confused. Is this the only way?

• Having problems with uploading photos to TwitPic using OAuth in Objective C on the iPhone

  - by M. Bedi

  I have been working on an iPhone app that has a feature of uploading photos to TwitPic. I have it working with basic authentication. I am trying to get it working with OAuth. I am getting authentication errors. I have studied very carefully the TwitPic documentation. I am authorising the app by displaying a UI Web View and the it returns a PIN value. I enter the PIN value in the app and request the token. I am able to upload status updates to Twitter but not photos. My code is based on some example code from here: Example iPhone app using OAuth Here is my code: NSString *url = @"http://api.twitpic.com/2/upload.json"; NSString *oauth_header = [oAuth oAuthHeaderForMethod:@"POST" andUrl:url andParams:nil]; NSLog(@"OAuth header : %@\n\n", oauth_header); ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:url]]; [request addRequestHeader:@"User-Agent" value:@"ASIHTTPRequest"]; request.requestMethod = @"POST"; [request addRequestHeader:@"X-Auth-Service-Provider" value:@"https://api.twitter.com/1/account/verify_credentials.json"]; [request addRequestHeader:@"X-Verify-Credentials-Authorization" value:oauth_header]; NSData *imageRepresentation = UIImageJPEGRepresentation(imageToUpload, 0.8); [request setData:imageRepresentation forKey:@"media"]; [request setPostValue:@"Some Message" forKey:@"message"]; [request setPostValue:TWITPIC_API_KEY forKey:@"key"]; [request setDelegate:self]; [request setDidFinishSelector:@selector(requestDone:)]; [request setDidFailSelector:@selector(requestFailed:)]; [request start]; Here is the OAuth Header: OAuth realm="http://api.twitter.com/", oauth_timestamp="1275492425", oauth_nonce="b686f20a18ba6763ac52b689b2ac0c421a9e4013", oauth_signature_method="HMAC-SHA1", oauth_consumer_key="zNbW3Xi3MuS7i9cpz6fw", oauth_version="1.0", oauth_token="147275699-jmrjpwk3B6mO2FX2BCc9Ci9CRBbBKYW1bOni2MYs", oauth_signature="d17HImz6VgygZgbcp845CD2qNnI%3D"
