  • In WPF, how do I get a command in a Control Template to bind to a property in a parent?

    - by Keith
    I am relatively new to WPF and sometimes it makes my head explode. However, I do like the power behind it, especially when used with the MVVM model. I have a control template that contains a button. I use that control template inside of a custom control. I want to add a property on the custom control that will bind to the command property of the button inside the control template. Basically, it is a combo box with a button to the right of it to allow a user to pop up a search dialog. Since this control could appear on a usercontrol multiple times, I need to be able to potentially bind each control to a different command (Searh products, search customers, etc). However, I have been unable to figure out how to do this Here is some sample XAML <Style TargetType="{x:Type m:SelectionFieldControl}"> <Setter Property="LookupTemplate" Value="{StaticResource LookupTemplate}" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type m:SelectionFieldControl}"> <Border BorderThickness="{TemplateBinding Border.BorderThickness}" Padding="{TemplateBinding Control.Padding}" BorderBrush="{TemplateBinding Border.BorderBrush}" Background="{TemplateBinding Panel.Background}" SnapsToDevicePixels="True" Focusable="False"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" MinWidth="0" SharedSizeGroup="{Binding LabelShareSizeGroupName, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:BaseFieldControl}}}" /> <ColumnDefinition Width="1*" /> <ColumnDefinition Width="Auto" SharedSizeGroup="{Binding WidgetsShareSizeGroupName, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:BaseFieldControl}}}" /> </Grid.ColumnDefinitions> <!-- Customized Value Part --> <ComboBox x:Name="PART_Value" Grid.Column="1" Margin="4,2,0,1" SelectedValue="{Binding Path=SelectionField.Value, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:SelectionFieldControl}}}" IsEnabled="{Binding Field.IsNotReadOnly, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:SelectionFieldControl}}}" Visibility="{Binding Field.IsInEditMode, Converter={StaticResource TrueToVisible}, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:SelectionFieldControl}}}" FontFamily="{StaticResource FontFamily_Default}" FontSize="11px"> <ComboBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel IsVirtualizing="True" VirtualizationMode="Recycling"/> </ItemsPanelTemplate> </ComboBox.ItemsPanel> </ComboBox> <StackPanel Grid.Column="2" Orientation="Horizontal" Name="PART_Extra" Focusable="False"> <ContentControl Name="PART_LookupContent" Template="{Binding LookupTemplate, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:SelectionFieldControl}}}" Focusable="False"/> </StackPanel> </Grid> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> I thought I could get it to work by doing something like this <Button Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type SelectionFieldControl}}, Path=ShowSearchCommand}" Margin="2" /> but it does not work. Any help would be greatly appreciated.

  • Loading Separate Pages With Animation in JQTouch

    - by Donovan Keith
    I'm trying to convert a database-driven multiple-choice-style study website (written in JSP) into an iPhone app using JQTouch. If I load all of the Q&A's into their own divs in the same file I can easily link and animate between them using links to hashtags, like: a class="button" href="#question22" Unfortunately this isn't practical. The logic of the website as it currently works requires calls to a number of dynamically generated pages; I can't include every question in its own div in the same flat file. How would I go about dynamically (pre)loading the next question (a JSP page like AskQuestion.jsp?questionId=Kzhctand ) then serving that up within the app after the user presses a button? Thanks for any help you might offer. -Donovan

  • 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) )

  • LINQ 4 XML - What is the proper way to query deep in the tree structure?

    - by Keith Barrows

I would like to do a LINQ query against a class set that was deserialized from this XML. For instance: ToAddress = [email protected] FromAddress = [email protected] Query: Get EmailRule.Include(Parse).Include(TargetPST) where address == ToAddress AND Parse.ToAddress==true AND Parse.useJustDomain==false Get EmailRule.Include(Parse).Include(TargetPST) where address == [ToAddress Domain Only] AND Parse.ToAddress==true AND Parse.useJustDomain==true Get EmailRule.Include(Parse).Include(TargetPST) where address == FromAddress AND Parse.FromAddress==true AND Parse.useJustDomain==false Get EmailRule.Include(Parse).Include(TargetPST) where address == [FromAddress Domain Only] AND Parse.FromAddress==true AND Parse.useJustDomain==true I am having a hard time figuring this LINQ query out. I can, of course, loop on all the bits in the XML like so (includes deserialization into objects): XmlSerializer s = new XmlSerializer(typeof(EmailRuleList)); TextReader r = new StreamReader(path); _emailRuleList = (EmailRuleList)s.Deserialize(r); TargetPST[] PSTList = _emailRuleList.Items; foreach (TargetPST targetPST in PSTList) { olRoot = GetRootFolder(targetPST.name); if (olRoot != null) { Parse[] ParseList = targetPST.Items; foreach (Parse parseRules in ParseList) { EmailRule[] EmailRuleList = parseRules.Items; foreach (EmailRule targetFolders in EmailRuleList) { } } } } However, this means going through all these loops for each and every address. It makes more sense to me to query against the Objects. Any tips appreciated!

  • C# WMI, Performance Counters, & SNMP Oh My!

    - by Keith
    I have a C# windows service which listens to a MSMQ and sends each message out as an email. Since there's no UI, I'd like to offer an ability to monitor this service to see things such as # messages in queue, # emails sent (by message type perhaps), # of errors, etc. What is the best/recommended way to accomplish this? Is it WMI or performance counters? Is this data viewed using PerfMon or WMI CIM Studio? Does any approach allow one to monitor the service real-time as well as providing historical analysis? I can dig into the details myself but would appreciate some broad guidance to help demystify this subject.

  • How to use Microsoft.Web.Administration.dll to get the site information the page is running on?

    - by Keith Barrows
    I have a half dozen sites on my server and I would like to get some info from IIS7 to display in the footer of each page (as long as you are an admin of course). I am going through the ServerObject and found Sites but am not finding anything obvious for "this site". What should I do to get at the information for the exact site in IIS7 that the page is running on? For a quick 'hack' style approach I wrote this on my default.aspx page code behind: ServerManager serverMgr = new ServerManager(); foreach (Site site in serverMgr.Sites) { string s = info.Text + site.Name + @"<br/>"; info.Text = s; foreach (Binding binding in site.Bindings) { string t = info.Text + binding.BindingInformation + " | "; string p = t + binding.Protocol + @"<br/>"; info.Text = p; } } TIA

  • Resharper and ViEmu Keybindings ( and Visual Assist )

    - by Keith Nicholas
    With ViEmu you really need to unbind a lot of resharpers keybindings to make it work well. Does anyone have what they think is a good set of keybindings that work well for resharper when using ViEmu? What I'm doing at the moment using the Visual Studio bindings from Resharper. Toasting all the conflicting ones with ViEmu, and then just driving the rest through the menu modifiers ( Alt-R keyboard shortcut for the menu item ). I also do the same with Visual Assist shortcuts ( for C++ ) if anyones got any tips and tricks for ViEmu / Resharper or Visual Assist working together well I'd most apprciate it!

  • Is there an iconv with //TRANSLIT equivalent in java?

    - by Keith
    Is there a way to achieve transliteration of characters between charsets in java? something similar to the unix command (or similar php function): iconv -f UTF-8 -t ASCII//TRANSLIT < some_doc.txt > new_doc.txt preferably operating on strings, not having anything to do with files I know you can can change encodings with the String constructor, but that doesn't handle transliteration of characters that aren't in the resulting charset.

  • Getting error detail from WCF REST

    - by Keith
    I have a REST service consumed by a .Net WCF client. When an error is encountered the REST service returns an HTTP 400 Bad Request with the response body containing JSON serialised details. If I execute the request using Fiddler, Javascript or directly from C# I can easily access the response body when an error occurs. However, I'm using a WCF ChannelFactory with 6 quite complex interfaces. The exception thrown by this proxy is always a ProtocolException, with no useful details. Is there any way to get the response body when I get this error? Update I realise that there are a load of different ways to do this using .Net and that there are other ways to get the error response. They're useful to know but don't answer this question. The REST services we're using will change and when they do the complex interfaces get updated. Using the ChannelFactory with the new interfaces means that we'll get compile time (rather than run time) exceptions and make these a lot easier to maintain and update the code. Is there any way to get the response body for an error HTTP status when using WCF Channels?

  • Get a list of members of a WinNT group (C#)

    - by Keith Moore
    There are a couple of questions similar to this on stack overflow but not quite the same. I want to open, or create, a local group on a win xp computer and add members to it, domain, local and well known accounts. I also want to check whether a user is already a member so that I don't add the same account twice, and presumably get an exception. So far I started using the DirectoryEntry object with the WinNT:// provider. This is going ok but I'm stuck on how to get a list of members of a group? Anyone know how to do this? Or provide a better solution than using DirectoryEntry?

  • Sharing the model in MVP Winforms App

    - by Keith G
    I'm working on building up an MVP application (C# Winforms). My initial version is at http://stackoverflow.com/questions/1422343/ ... Now I'm increasing the complexity. I've broken out the code to handle two separate text fields into two view/presenter pairs. It's a trivial example, but it's to work out the details of multiple presenters sharing the same model. My questions are about the model: I am basically using a property changed event raised by the model for notifying views that something has changed. Is that a good approach? What if it gets to the point where I have 100 or 1000 properties? Is it still practical at that point? Is instantiating the model in each presenter with   NoteModel _model = NoteModel.Instance   the correct approach? Note that I do want to make sure all of the presenters are sharing the same data. If there is a better approach, I'm open to suggestions .... My code looks like this: NoteModel.cs public class NoteModel : INotifyPropertyChanged { private static NoteModel _instance = null; public static NoteModel Instance { get { return _instance; } } static NoteModel() { _instance = new NoteModel(); } private NoteModel() { Initialize(); } public string Filename { get; set; } public bool IsDirty { get; set; } public readonly string DefaultName = "Untitled.txt"; string _sText; public string TheText { get { return _sText; } set { _sText = value; PropertyHasChanged("TheText"); } } string _sMoreText; public string MoreText { get { return _sMoreText; } set { _sMoreText = value; PropertyHasChanged("MoreText"); } } public void Initialize() { Filename = DefaultName; TheText = String.Empty; MoreText = String.Empty; IsDirty = false; } private void PropertyHasChanged(string sPropName) { IsDirty = true; if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(sPropName)); } } public event PropertyChangedEventHandler PropertyChanged; } TextEditorPresenter.cs public class TextEditorPresenter { ITextEditorView _view; NoteModel _model = NoteModel.Instance; public TextEditorPresenter(ITextEditorView view)//, NoteModel model) { //_model = model; _view = view; _model.PropertyChanged += new PropertyChangedEventHandler(model_PropertyChanged); } void model_PropertyChanged(object sender, PropertyChangedEventArgs e) { if (e.PropertyName == "TheText") _view.TheText = _model.TheText; } public void TextModified() { _model.TheText = _view.TheText; } public void ClearView() { _view.TheText = String.Empty; } } TextEditor2Presenter.cs is essentially the same except it operates on _model.MoreText instead of _model.TheText. ITextEditorView.cs public interface ITextEditorView { string TheText { get; set; } } ITextEditor2View.cs public interface ITextEditor2View { string MoreText { get; set; } }

  • SQL Server database backup: Network Service file access

    - by Keith Maurino
    When trying to run the following database backup command from my code I get an "Operating system error 5(Access is denied.)" error. This is because the log on account for the SQL Server Windows Service is 'Network Service' and that does not have access to right to this folder. BACKUP DATABASE [AE3DB] TO DISK = 'c:\AE3\backup\AE3DB.bak' My question is, from my code how would I go about figuring out where on the C drive 'Network Service' is allowed to right the backup to? NOTE: This is a distributed application so I cannot easily change the log on for the SQL Server Windows Service to the 'Local System' account that would be able to right to that folder.

  • Python - Linux - Connecting to MS SQL with Windows Credentials - FreeTDS+UnixODBC + pyodbc or pymssq

    - by Keith P
    There doesn't seem to be any great instructions for setting this up. Does anyone have any good instructions? I am a linux noob so be gentle. I did see another post that is similar, but no real answer. I have a couple of problems. FreeTDS doesn't "seem" to be working. I am trying to connect and I get the following message using the "tsql" command: "Default database being set to databaseName There was a problem connecting to the server" but it doesn't mention what the problem is. The error I get when I try to connect using pyodbc is: "pyodbc.Error: ('08S01', '[08S01] [unixODBC][FreeTDS][SQL Server]Unable to connect: Adaptive Server is unavailable or does not exist (20009) (SQLDriverConnectW)')" I tried something similar with pymssql, but I ran into similar issues. I keep getting errors that I can't connect, but it doesn't tell me why.

  • jQuery CSS plugin that returns computed style of element to pseudo clone that element?

    - by Keith Bentrup
    I'm looking for a way using jQuery to return an object of computed styles for the 1st matched element. I could then pass this object to another call of jQuery's css method. For example, with width, I can do the following to make the 2 divs have the same width: $('#div2').width($('#div1').width()); It would be nice if I could make a text input look like an existing span: $('#input1').css($('#span1').css()); where .css() with no argument returns an object that can be passed to .css(obj). (I can't find a jQuery plugin for this, but it seems like it should exist. If it doesn't exist, I'll turn mine below into a plugin and post it with all the properties that I use.) Basically, I want to pseudo clone certain elements but use a different tag. For example, I have an li element that I want to hide and put an input element over it that looks the same. When the user types, it looks like they are editing the element inline. I'm also open to other approaches for this pseudo cloning problem for editing. Any suggestions? Here's what I currently have. The only problem is just getting all the possible styles. This could be a ridiculously long list. jQuery.fn.css2 = jQuery.fn.css; jQuery.fn.css = function() { if (arguments.length) return jQuery.fn.css2.apply(this, arguments); var attr = ['font-family','font-size','font-weight','font-style','color', 'text-transform','text-decoration','letter-spacing','word-spacing', 'line-height','text-align','vertical-align','direction','background-color', 'background-image','background-repeat','background-position', 'background-attachment','opacity','width','height','top','right','bottom', 'left','margin-top','margin-right','margin-bottom','margin-left', 'padding-top','padding-right','padding-bottom','padding-left', 'border-top-width','border-right-width','border-bottom-width', 'border-left-width','border-top-color','border-right-color', 'border-bottom-color','border-left-color','border-top-style', 'border-right-style','border-bottom-style','border-left-style','position', 'display','visibility','z-index','overflow-x','overflow-y','white-space', 'clip','float','clear','cursor','list-style-image','list-style-position', 'list-style-type','marker-offset']; var len = attr.length, obj = {}; for (var i = 0; i < len; i++) obj[attr[i]] = jQuery.fn.css2.call(this, attr[i]); return obj; } Edit: I've now been using the code above for awhile. It works well and behaves exactly like the original css method with one exception: if 0 args are passed, it returns the computed style object. As you can see, it immediately calls the original css method if that's the case that applies. Otherwise, it gets the computed styles of all the listed properties (gathered from Firebug's computed style list). Although it's getting a long list of values, it's quite fast. Hope it's useful to others.

  • Entity Framework - Merging 2 physical tables into one "virtual" table problems...

    - by Keith Barrows
    I have been reading up on porting ASP.NET Membership Provider into .NET 3.5 using LINQ & Entities. However, the DB model that every single sample shows is the newer model while I've inherited a rather old model. Differences: The User Table is split into a pair of User & Membership Tables. All of the tables in the DB are prepended with aspnet_ I have Lowered versions of some columns (UserName, Email, etc) To work with this I have copied the properties from the Membership table into the User table (in the DB this is a 1<-1 relationship, not a 1<-0,1), renamed aspnet_Applications to Application, aspnet_Profiles to Profile, aspnet_Users to User and aspnet_Roles to Role. (See image) Link to full size image of model Now, I am running into one of 2 problems when I try to compile. Using the model in the image I get this error: Problem in Mapping Fragment starting at line 464: EntitySets 'UserSet' and 'aspnet_Membership' are both mapped to table 'aspnet_Membership'. Their Primary Keys may collide. If I delete the aspnet_Membership table from my model (to handle the above error) I then get: Problem in Mapping Fragment starting at line 384: Column aspnet_Membership.ApplicationId in table aspnet_Membership must be mapped: It has no default value and is not nullable. My ability to hand edit the backing stores is not the best and I don't want to just hack something in that may break other things. I am looking for suggestions, best practices, etc to handle this. Note: Moving the data tables themselves is not an option as I cannot replace all the logic in the existing apps. I am building this EF Provider for a new App. Over the next 6 months the old app(s) will migrate bit-by-bit to the new structures. Note: I added a link just under the image to the full size image for better viewing.

  • "Cannot open user default database" error with "User Instance=True"

    - by Keith
    I have a desktop application that uses Sql user instancing. This is my connection string: "Data Source=.\SqlExpress; AttachDbFilename=C:\path\file.mdf; Integrated Security=True; User Instance=True; Connect Timeout=100;" My application creates this DB, downloads a load of data into it from a web service and then does a lot of actions with it. The problem comes when I attempt to re-open the connection. I get a SqlException: "Cannot open user default database. Login failed. Login failed for user 'myDomain\myusername'." This error makes no sense in this context - I have no default database. I'm logging in to an instance created just for the current application, running separately from SqlExpress. There's no other way to connect to this DB. If I start the SqlExpress service and connect to the default instance it won't be visible. It only exists for this application. The file on disk is locked by the SqlExpress instance service running under the application. if I stop the app and restart it the connection works first time, but fails on re-opening. If I just stop the app I can delete the .mdf files and begin again, but it still crashes when I re-open the connection. As my app started the instance running as me my current user should have access to every DB in the instance. This doesn't happen for other users of the same code, which suggests that it's a SQL config issue. Does anyone have any idea what causes this and how to work around it?

  • iPhone GPS Development - Tips + Tricks

    - by Keith Fitzgerald
    Hello - I'm looking for some feedback, blog links, etc that offer some tips and tricks for iPhone GPS development. I've read and understand the API, I have my demo app up and running, etc but I have run into some "quirks" with gps on iphone. For example, it seems that you you will receive a lot less location updates when your iphone enters "power save" mode. I've read that you can combat this by playing music in your application [not sure if this is true]. It also seems that, terms of making a reasonable pedometer, you should filter out any reading with horizontal accuracies less than 20 meters. Does this sound right? Is there any kind of checklist out on the web for iphone gps gotchas? Thanks in advance.

ERROR: Error installing rmagick: ERROR: Failed to build gem native extension. /usr/local/bin/ruby extconf.rb checking for Ruby version >= 1.8.5... yes checking for gcc... yes checking for Magick-config... no Can't install RMagick 2.11.0. Can't find Magick-config in /usr/bin:/bin *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=/usr/local/bin/ruby Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.11.0 for inspection. Results logged to /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.11.0/ext/RMagick/gem_make.out The directory /usr/local/bin contains Magick-config but I haven't been able to get rubygems to look there. I tried the following but the result was the same: sudo gem install rmagick -- --with-opt-dir=/usr/local/bin Any suggestions would be appreciated.

  • How to temporarily replace one primitive type with another when compiling to different targets in c#

    - by Keith
    How to easily/quickly replace float's for doubles (for example) for compiling to two different targets using these two particular choices of primitive types? Discussion: I have a large amount of c# code under development that I need to compile to alternatively use float, double or decimals depending on the use case of the target assembly. Using something like “class MYNumber : Double” so that it is only necessary to change one line of code does not work as Double is sealed, and obviously there is no #define in C#. Peppering the code with #if #else statements is also not an option, there is just too much supporting Math operators/related code using these particular primitive types. I am at a loss on how to do this apparently simple task, thanks! Edit: Just a quick comment in relation to boxing mentioned in Kyles reply: Unfortunately I need to avoid boxing, mainly since float's are being chosen when maximum speed is required, and decimals when maximum accuracy is the priority (and taking the 20x+ performance hit is acceptable). Boxing would probably rules out decimals as a valid choice and defeat the purpose somewhat. Edit2: For reference, those suggesting generics as a possible answer to this question note that there are many issues which count generics out (at least for our needs). For an overview and further references see Using generics for calculations

  • How can you centre an image within the image control in SQL Server Reporting Services 2008?

    - by Keith
    I have got an image in an image control on a report in SSRS 2008. The image is coming from an external source, and varies in width. I would like to centre the image within the control, but the image control does not have an equivalent of the text box's TextAlign property to allow right/left/center alignment to be done automatically. I have seen methods to dynamically calculate the amount of left padding as a hack to solve this, http://blogs.msdn.com/chrishays/archive/2004/10/27/CenteredImages.aspx, but the solution gives an error in SSRS 2008, perhaps not surprising given the age of the article. Has anybody got a solution to this for SSRS 2008?

  • Can you recommend an alternative for NCover?

    - by Keith
    I'm looking for a good .Net code coverage alternative to NCover (insufficient .Net 3.5 coverage and now pay-for) or VSTS (way too expensive). We currently test with NUnit, but could switch to something with a similar 'layout' for its text fixtures if it were better integrated.
