• Blog Rebranding

  I have been spending more and more time on learning as much as I can on Agile Development and also have been fairly immersed in rolling out TFS 2010 in our environment.  I feel like it is time to talk about some of my experiences.  With that, I am rebranding my blog to focus on these topics.  I am going to start with a bunch of blogs on the process I have gone through getting TFS 2010 configured for our development teams. Last week, Brian Harry was in our office and gave a great talk on the improved tools in TFS 2010 and how Microsoft uses the tools internally.  I followed that up with a high-level overview of the improved out of the box process templates and the process to customize them.  I am definitely very excited about the new features in 2010 and hopefully will keep up my motivation to blog about it.  I am writing my first post right now about the process I went through to build a task progress report based on the user story progress report in the MSF for Agile Development template.  Stay tunedDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Using Git with TFS projects

  If you having been following the updates to CodePlex over the last several months you will have noticed that we added support for Git source control. It is important to the CodePlex team to enable developers to use the source control system that supports their development style whether it is distributed version control or centralized version control. There are many projects on CodePlex that are using TFS centralized version control. But we continue to see more and more developers interested in using Git. Last week Brian Harry announced a new open source project called Git-TF. Git-TF is a client side bridge that enabled developer to use Git locally and push to a remote backed by Team Foundation version control. Git-TF also works great for TFS based projects on CodePlex. You may already be familiar with git-tfs. Git-TFS is a similar client side bridge between Git and TFS. Git-TFS works great if you are on Windows since it depends on the TFS .Net client object model. Git-TF adds the ability to use a Git to TFS bridge on multiple platforms since it is written in Java. You can use it on Mac OS X, Linux, and Windows, etc. Since you are connecting to a TFS Server when using Git-TF make sure you use your CodePlex TFS account name: snd\YOUR_USERNAME_cp along with your password. At this point, you will need to be a member of the project to connect using Git-TF. Resources Git-TF Getting Started Guide Download: Git-TF Git-TF Source on CodePlex

• WCF - problem with local service (The server has rejected the client credentials.)

  - by H4mm3rHead

  Hi, I have a simple setup, a WPF application running on the machine and a WCF service hosted within a Windows Service on the same machine (always on the same machine). When i debug on one computer i can easily access the local WCF Service. When i run it on another machine i get an error: "The server has rejected the client credentials." Some of my observations are, that at my local machine i have no domain/network. Its my home machine. When at a customers site, it will not run, and gives the above error. Anyone got any ideas on why this is different on these computers? /Brian

• How to avoid OLEDB converting "."s into "#"s in column names?

  - by Andrew Miner

  I'm using the ACE OLEDB driver to read from an Excel 2007 spreadsheet, and I'm finding that any '.' character in column names get converted to a '#' character. For example, if I have the following in a spreadsheet: Name Amt. Due Due Date Andrew 12.50 4/1/2010 Brian 20.00 4/12/2010 Charlie 1000.00 6/30/2010 the name of the second column would be reported as "Amt# Due" when read with the following code: OleDbConnection connection = new OleDbConnection( "Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; " + "Extended Properties=\"Excel 12.0 Xml;HDR=YES;FMT=Delimited;IMEX=1\""); OldDbCommand command = new OleDbCommand("SELECT * FROM MyTable", connection); OleDbReader dataReader = command.ExecuteReader(); System.Console.WriteLine(dataReader.GetName(1)); I've read through all the documentation I can find and I haven't found anything which even mentions that this will happen. Has anyone run into this before? Is there a way to fix this behavior?

• Linq to SQl over WCF Timesout after several calls

  - by Redeemed1

  I have a L2S Repository class which instantiates the L2S DataContext in its constructor. The repository is instantiated at run time (using Unity) in a service hosted in IIS with WCF. When I run up the client MVC applicaton the calls to the backend WCF service work for a while and then timeout. I suspected perhaps a database issue as I was depending on IIS garbage collection to dispose of unused DataContext instances in the IIS host but when I checked the characteristics of the problem I notice the following: The client makes the call to WCF but the WCF service does not respond. Next, the client times out Some time later (several minutes) the service actually executes the request by instantiating the repository and servicing the call. I have checked both client and server traces logs and only the client shows WCF errors (the timeout error). Where should I look? Is it something in WCF or is L2S possibly blocking with unfreed conenctions, resources etc.? Many thanks Brian

• Prolog Program for a recordings database

  - by RP

  I have three types of facts: album(code, artist, title, date). songs(code, songlist). musicians(code, list). Example: album(123, 'Rolling Stones', 'Beggars Banquet', 1968). songs(123, ['Sympathy for the Devil', 'Street Fighting Man']). musicians(123, [[vocals, 'Mick Jagger'], [guitar, 'Keith Richards', 'Brian Jones']]. I need to create these 4 rules: together(X,Y) This succeeds if X and Y have played on the same album. artistchain(X,Y) This succeeds if a chain of albums exists from X to Y; two musicians are linked in the chain by 'together'. role(X,Y) This succeeds if X had role Y (e.g. guitar) ever. song(X,Y) This succeeds if artist X recorded song Y. Any help?

• Strange Exception on getGeneratedKeys() with JDBC for MySQL 5.1

  - by sweeney

  Hello, I'm using JDBC to insert a row into a MYSQL database. I build a parameterized command, execute it and attempt to retrieve the auto generated keys as follows: String sql = "INSERT IGNORE INTO `users` (`email`, `pass-hash`) VALUES (?, ?)"; Connection conn = SQLAccess.getConnection(); PreparedStatement ps = conn.prepareStatement(sql); ps.setString(1, login); ps.setString(2, passHash); int count = ps.executeUpdate(); if (count == 1) { ResultSet rs = ps.getGeneratedKeys(); rs.next(); //some more stuff... } For some reason, I get the following SQLException on the line containing ResultSet rs = ps.getGeneratedKeys();: !Statement.Generated Keys Not Requested! Any thoughts? When I run the same query, as generated by running the app through the debugger, in a MySQL browser it executes without incident. Thanks, brian

• Procedural music generation?

  - by anon

  Anyone have good book / article recommendation for procedural generation of background music? (No vocals, just instruments). I'm not interested in: How do I generate the sound of a particular note on a particular instrument I'm interested in: How do I generate the melody / score for the music. Thanks! EDIT: Thanks for the reference to Brian Eno. I'm definitely looking into the ambient/user can ignore type of music. I.e. think the background music of a game. It's there to provide some basic mood, but the focus is the game.

• Overriding Doctrine_Record (sfDoctrineRecord) instance methods in Doctrine PHP Symfony

  - by notbrain

  My background is in Propel, so I was hoping it would be a simple thing to override a magical getter in a Doctrine_Record (sfDoctrineRecord), but I'm getting either a Segfault or the override method is simply ignored in favor of the one in the superclass. https://gist.github.com/697008eaf4d7b606286a class FaqCategory extends BaseFaqCategory { public function __toString() { return $this->getCategory(); } // doesn't work // override getDisplayName to fall back to category name if getDisplayName doesn't exist public function getDisplayName() { // also tried parent::getDisplayName() but got segfault(!) if(isset($this->display_name)) { $display_name = $this->display_name; } else { $display_name = $this->category; } return $display_name; } } What is the proper Doctrine way to extend/override methods on an instance of Doctrine_Record (via sfDoctrineRecord extends Doctrine_Record)? This has to be doable...or should I be looking at the Template documentation? Thanks, Brian

• Will WF 4.0 make me Obsolete

  - by codemnky

  I saw a post on Oslo about making us obsolete. I just happened to listen to the latest Deep Fried Episode with Brian Noyes. They were talking about SharePoint and Windows Workflow and how the "dream" of Windows Workflow is to let mere Business Analyst Drag and Drop their way to a functioning service. I am a newbie dotnet developer, and afraid that by the time I get to Consulting "Level" my skills would be obsolete. Should I abandon learning basic skills and just learn how to work with Frameworks and Packaged applications such as SAP, SharePoint, BizTalk. Am I wasting time trying to learn Expression Trees and Func of T's?

• MVC on Server 2008 R2 - How?

  - by Redeemed1

  I have a new WIndows Server 2008 R2 x64 DataCentre with Framework 3.5 SP1 and Framework 4 installed. When I install my MVC application (VS 2008 MVC 2.0 using a Web Setup project installer) and browse to the application I get an error that System.Web.Mvc cannot be found. If I copy the relevant DLLs (System.Web.Mvc etc)into the bin directory the app runs up perfectly. I have checked everywhere for an installer but can only find the VS2008 related bits, no server runtime. How do I get ASP.Net MVC installed in this environment so that we don't have to Copy Local the dlls? Many thanks Brian

• Evaluation of jQuery function variable value during definition of that function

  - by thesnail

  I have a large number of rows in a table within which I wish to attach a unique colorpicker (jQuery plugin) to each cell in a particular column identified by unique ids. Given this, I want to automate the generation of instances of the colorpicker as follows: var myrows={"a","b","c",.....} var mycolours={"ffffff","fcdfcd","123123"...} for (var i=0;i<myrows.length;i++) { $("#"+myrows[i]+"colour").ColorPicker({flat: false, color: mycolours[i], onChange: function (hsb, hex, rgb) { $("#"+myrows[i]+"currentcolour").css('backgroundColor', '#' + hex); } }); Now this doesn't work because the evaluation of the $("#"+myrows[i]+"currentcolour") component occurs at the time the function is called, not when it is defined (which is want I need). Given that this plugin javascript appends its code to the level and not to the underlying DOM component that I am accessing above so can't derive what id this pertains to, how can I evaluate the variable during function declaration/definition? Thanks for any help/insight anyone can give. Brian.

• Problem with absolute positioning div over SWF and IE 8.

  - by Michael S. Kelly

  I'm attempting to use the old IFrame-over-SWF trick to get HTML to display "inside" a SWF. I'm following the example provided by Brian Deitte at: http://www.deitte.com/IFrameDemo3/IFrameDemo.html. (The source code can be viewed and downloaded by right-clicking on the SWF and selecting "View Source".) In the latest versions of Firefox, Google, Opera, and Safari on the Mac, it all looks good. But in IE 8 the absolutely positioned div containing the IFrame is positioned too far up and left, and the height and width are considerably smaller. Thoughts?

• How do I find the user that has both a cat and a dog?

  - by brad

  I want to do a search across 2 tables that have a many-to-one relationship, eg class User << ActiveRecord::Base has_many :pets end class Pet << ActiveRecord::Base belongs_to :users end Now let's say I have some data like so users id name 1 Bob 2 Joe 3 Brian pets id user_id animal 1 1 cat 2 1 dog 3 2 cat 4 3 dog What I want to do is create an active record query that will return a user that has both a cat and a dog (i.e. user 1 - Bob). My attempt at this so far is User.joins(:pets).where('pets.animal = ? AND pets.animal = ?','dog','cat') Now I understand why this doesn't work - it's looking for a pet that is both a dog and a cat so returns nothing. I don't know how to modify this to give me the answer I want however. Does anyone have any suggestions? This seems like it should be easy - it doesn't seem like an especially unusual situation.
