• Xobni Plus for Outlook [Review]

  - by The Geek

  Overview Xobni Plus is an addin that will bring a sidebar to Outlook which allows you to search through your inbox and contacts a lot easier. It provides the ability to search and keep track of your favorite social networks. Searching with Xobni is a lot more powerful than the default search feature in Outlook. It let’s you drill down your searches to conversations, email, links, and attachments. It now supports Outlook 2010 both 32 & 64-bit versions. Installation & Setup Installation is easy following the wizard. After completing the wizard you can tell you’re friends on Facebook and Twitter that you are now using it. You can also decide to join their Product Improvement Program if you want. After installation when you open Outlook, Xobni appears as a sidebar on the right side. Don’t worry about it always being in the way, as you can hide it if you need more room for other Outlook functions. After Xobni free is installed, you can upgrade to the Plus version at any time. A new window will open up and you can use your Credit Card, PayPal, or redeem a code if you have one. Features & Use Where to begin with the amount of features available in Xobni Plus? It really has an amazing amount of cool features. Of course you’ll have all of the features of the Free Version which we previously covered…and a lot more. After Xobni is installed you’ll notice a section for it on the Ribbon. From here you can search Xobni, show or hide the Sidebar, and change other options. It allows you to easily keep up with various social networks like Facebook, Twitter, and LinkedIn… Check out email analytics and contact ranks. Click on the Files Exchanged tab to search for specific attachments. Quickly search links exchanged with your contacts. Hover over a link to get a preview of what it entails. It gives you the ability to index all of your Yahoo mail as well, without the need for purchasing Yahoo Plus! Then your Yahoo messages appear in the Xobni sidebar. When you select a contact you can see related messages from you Yahoo account. Easily index all of your mail…including Yahoo mail for better organization and faster search results. There are several options you can select to change the way Xobni works. From setting up your Yahoo email, Indexing options, and much more. Additional Features of Xobni Plus Advanced Search Capabilities – Filter results, Boolean & Phrase Search, Ability to search Appointments & Tasks, Advanced Search Builder Search unlimited PST data files Xobni contacts in the compose screen Find links exchanged with your contacts View calendar appointments One year premium tech support No Ads! Performance We ran Xobni Plus on Outlook 2010 32-bit on a Dual-Core AMD Athlon system with 4GB of RAM and found it to run quite smoothly. However, we did notice it would sometimes slow down launching Outlook, especially if other apps are running at the same time. Product Support When you buy a license for Xobni Plus you get a full year of premium tech support. They provide a Questions and Answers page on their site where you can run a search query and answers appear instantly. You can contact support directly as a Plus member through their web form and they advise the turn around time is 2 business days. However, when we tested it, we received a response within 24 hours. They also provide FAQ, Community forum, and you can download the Owners Manual in PDF format from the support page. Conclusion Xobni Plus is a very powerful addin for Outlook and includes a lot more features that we didn’t cover in this review. You can download Xobni free edition which includes an 8 day free trial of the Plus version. This provides a good way to start getting familiar with it. Then upgrade to Xobni Plus at any time for $29.95. Once you get started, you’ll find the sidebar is nicely laid out and intuitive to use. If you live out of Outlook during the day, Xobni Plus is a great addition for fast and powerful searches. It provides an easy way to keep all of your contacts and messages well organized and easy to find.

• Silverlight Relay Commands

Which I enjoy, since I like the idea of going into a day knowing that I am  going to learn something new. The issue that I am currently working on centers around relay commands. I have a pretty good handle on Relay Commands and how we use them within our applications. <Button Command="{Binding ButtonCommand}" CommandParameter="NewRecruit" Content="New Recruit" /> Here in our xaml we have a button. The button has a Command and a CommandParameter. The command binds to the ButtonCommand that we have in our ViewModel RelayCommand _buttonCommand;         /// <summary>         /// Gets the button command.         /// </summary>         /// <value>The button command.</value>         public RelayCommand ButtonCommand         {             get             {                 if (_buttonCommand == null)                 {                     _buttonCommand = new RelayCommand(                         x => x != null && x.ToString().Length > 0 && CheckCommandAvailable(x.ToString()),                         x => ExecuteCommand(x.ToString()));                 }                 return _buttonCommand;             }         }   In our relay command we then do some checks with a lambda expression. We check if the command  parameter is null, is the length greater than 0 and we have a CheckCommandAvailable method that will tell  us if the button is even enabled. After we check on these three items we then pass the command parameter to an action method. This is all pretty straight forward, the issue that we solved a few days ago centered around having a control that needed to use a Relay Command and this control was a nested control and was using a different DataContext. The example below illustrates how we handled this scenario. In our xaml usercontrol we had to set a name to this control. <Controls3:RadTileViewItem x:Class="RecruitStatusTileView"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"      xmlns:Controls1="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"      xmlns:Controls2="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input"      xmlns:Controls3="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"      mc:Ignorable="d" d:DesignHeight="400" d:DesignWidth="800" Header="{Binding Title,Mode=TwoWay}" MinimizedHeight="100"                             x:Name="StatusView"> Here we are using a telerik RadTileViewItem. We set the name of this control to “StatusView”. In our button control we set our command parameters and commands different than the example above. <HyperlinkButton Content="{Binding BigBoardButtonText, Mode=TwoWay}" CommandParameter="{Binding 'Position.PositionName'}" Command="{Binding ElementName=StatusView, Path=DataContext.BigBoardCommand, Mode=TwoWay}" /> This hyperlink button lives in a ListBox control and this listbox has an ItemSource of PositionSelectors. The Command Parameter is binding to the Position.Position property of that PositionSelectors object. This again is pretty straight forward again. What gets a bit tricky is the Command property in the hyperlink. It is binding to the element name we created in the user control (StatusView) Because this hyperlink is in a listbox and is in the item template it doesn’t have a direct handle on the DataContext that the RadTileViewItem has so we have to make sure it does. We do that by binding to the element name of status view then set the path to DataContext.BigBoardCommand. BigBoardCommand is the name of the RelayCommand in the view model. private RelayCommand _bigBoardCommand = null;         /// <summary>         /// Gets the big board command.         /// </summary>         /// <value>The big board command.</value>         public RelayCommand BigBoardCommand         {             get             {                 if (_bigBoardCommand == null)                 {                     _bigBoardCommand = new RelayCommand(x => true, x => AddToBigBoard(x.ToString()));                 }                 return _bigBoardCommand;             }         } From there we check for true again and then call the action and pass in the parameter that we had as the command parameter. What we are working on now is a bit trickier than this second example. In the above example we are only creating this TileViewItem with this name “StatusView” once. In another part of our application we are generating multiple TileViewItems, so we cannot set the name in the control as we cant have multiple controls with the same name. When we run the application we get an error that reads that the value is out of expected range. My searching has led me to think we cannot have multiple controls with the same name. This is today’s problem and Ill post the solution to this once it is found.

• concurrency::index<N> from amp.h

  - by Daniel Moth

  Overview C++ AMP introduces a new template class index<N>, where N can be any value greater than zero, that represents a unique point in N-dimensional space, e.g. if N=2 then an index<2> object represents a point in 2-dimensional space. This class is essentially a coordinate vector of N integers representing a position in space relative to the origin of that space. It is ordered from most-significant to least-significant (so, if the 2-dimensional space is rows and columns, the first component represents the rows). The underlying type is a signed 32-bit integer, and component values can be negative. The rank field returns N. Creating an index The default parameterless constructor returns an index with each dimension set to zero, e.g. index<3> idx; //represents point (0,0,0) An index can also be created from another index through the copy constructor or assignment, e.g. index<3> idx2(idx); //or index<3> idx2 = idx; To create an index representing something other than 0, you call its constructor as per the following 4-dimensional example: int temp[4] = {2,4,-2,0}; index<4> idx(temp); Note that there are convenience constructors (that don’t require an array argument) for creating index objects of rank 1, 2, and 3, since those are the most common dimensions used, e.g. index<1> idx(3); index<2> idx(3, 6); index<3> idx(3, 6, 12); Accessing the component values You can access each component using the familiar subscript operator, e.g. One-dimensional example: index<1> idx(4); int i = idx[0]; // i=4 Two-dimensional example: index<2> idx(4,5); int i = idx[0]; // i=4 int j = idx[1]; // j=5 Three-dimensional example: index<3> idx(4,5,6); int i = idx[0]; // i=4 int j = idx[1]; // j=5 int k = idx[2]; // k=6 Basic operations Once you have your multi-dimensional point represented in the index, you can now treat it as a single entity, including performing common operations between it and an integer (through operator overloading): -- (pre- and post- decrement), ++ (pre- and post- increment), %=, *=, /=, +=, -=,%, *, /, +, -. There are also operator overloads for operations between index objects, i.e. ==, !=, +=, -=, +, –. Here is an example (where no assertions are broken): index<2> idx_a; index<2> idx_b(0, 0); index<2> idx_c(6, 9); _ASSERT(idx_a.rank == 2); _ASSERT(idx_a == idx_b); _ASSERT(idx_a != idx_c); idx_a += 5; idx_a[1] += 3; idx_a++; _ASSERT(idx_a != idx_b); _ASSERT(idx_a == idx_c); idx_b = idx_b + 10; idx_b -= index<2>(4, 1); _ASSERT(idx_a == idx_b); Usage You'll most commonly use index<N> objects to index into data types that we'll cover in future posts (namely array and array_view). Also when we look at the new parallel_for_each function we'll see that an index<N> object is the single parameter to the lambda, representing the (multi-dimensional) thread index… In the next post we'll go beyond being able to represent an N-dimensional point in space, and we'll see how to define the N-dimensional space itself through the extent<N> class. Comments about this post by Daniel Moth welcome at the original blog.

• Stumbling Through: Visual Studio 2010 (Part II)

  I would now like to expand a little on what I stumbled through in part I of my Visual Studio 2010 post and touch on a few other features of VS 2010.  Specifically, I want to generate some code based off of an Entity Framework model and tie it up to an actual data source.  Im not going to take the easy way and tie to a SQL Server data source, though, I will tie it to an XML data file instead.  Why?  Well, why not?  This is purely for learning, there are probably much better ways to get strongly-typed classes around XML but it will force us to go down a path less travelled and maybe learn a few things along the way.  Once we get this XML data and the means to interact with it, I will revisit data binding to this data in a WPF form and see if I cant get reading, adding, deleting, and updating working smoothly with minimal code.  To begin, I will use what was learned in the first part of this blog topic and draw out a data model for the MFL (My Football League) - I dont want the NFL to come down and sue me for using their name in this totally football-related article.  The data model looks as follows, with Teams having Players, and Players having a position and statistics for each season they played: Note that when making the associations between these entities, I was given the option to create the foreign key but I only chose to select this option for the association between Player and Position.  The reason for this is that I am picturing the XML that will contain this data to look somewhat like this: <MFL> <Position/> <Position/> <Position/> <Team>     <Player>         <Statistic/>     </Player> </Team> </MFL> Statistic will be under its associated Player node, and Player will be under its associated Team node no need to have an Id to reference it if we know it will always fall under its parent.  Position, however, is more of a lookup value that will not have any hierarchical relationship to the player.  In fact, the Position data itself may be in a completely different xml file (something Id like to play around with), so in any case, a player will need to reference the position by its Id. So now that we have a simple data model laid out, I would like to generate two things based on it:  A class for each entity with properties corresponding to each entity property An IO class with methods to get data for each entity, either all instances, by Id or by parent. Now my experience with code generation in the past has consisted of writing up little apps that use the code dom directly to regenerate code on demand (or using tools like CodeSmith).  Surely, there has got to be a more fun way to do this given that we are using the Entity Framework which already has built-in code generation for SQL Server support.  Lets start with that built-in stuff to give us a base to work off of.  Right click anywhere in the canvas of our model and select Add Code Generation Item: So just adding that code item seemed to do quite a bit towards what I was intending: It apparently generated a class for each entity, but also a whole ton more.  I mean a TON more.  Way too much complicated code was generated now that code is likely to be a black box anyway so it shouldnt matter, but we need to understand how to make this work the way we want it to work, so lets get ready to do some stumbling through that text template (tt) file. When I open the .tt file that was generated, right off the bat I realize there is going to be trouble there is no color coding, no intellisense no nothing!  That is going to make stumbling through more like groping blindly in the dark while handcuffed and hopping on one foot, which was one of the alternate titles I was considering for this blog.  Thankfully, the community comes to my rescue and I wont have to cast my mind back to the glory days of coding in VI (look it up, kids).  Using the Extension Manager (Available under the Tools menu), I did a quick search for tt editor in the Online Gallery and quickly found the Tangible T4 Editor: Downloading and installing this was a breeze, and after doing so I got some color coding and intellisense while editing the tt files.  If you will be doing any customizing of tt files, I highly recommend installing this extension.  Next, well see if that is enough help for us to tweak that tt file to do the kind of code generation that we wantDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Common reasons for the &lsquo;Sys is undefined&rsquo; error in ASP.NET Ajax applications

    In this blog I will try to summarize the most common reasons for getting the famous 'Sys is undefined' error when running an Ajax enabled web site or application (there are almost one milion results on Google for that phrase). Where does it come from? In every Ajax web pages source you will see a code like this: <script type="text/javascript"> //<![CDATA[ Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('form1')); Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90); //]]> </script>   This is the initialization script of the ScriptManager. So, if for some reason the Sys namespace is not available when the code executes you get the Sys is undefined error. Here are the most common reasons and solutions for that problem:   1. The error occurs when you have added a control from RadControls for ASP.NET AJAX, but your application is not configured to use ASP.NET AJAX. For example, in VS 2005 you created a new Blank Site instead of a new Ajax-Enabled Web Site and the Sys is undefined message pops up. To fix it you need to follow the steps described at Configuring ASP.NET Ajax article (check the topic called Adding ASP.NET AJAX Configuration Elements to an Existing Web Site) or simply create the Ajax-Enabled Web Site. You can also check my other blog post on the matter: Visual Studio 2008: Where is the new ASP.NET Ajax-Enabled Web Site template?   2. Authentication - as the website denies access to all pages to unauthorized users, access to the Telerik.Web.UI.WebResource.axd handler is unauthorized (this is the default handler of RadScriptManager). This causes the handler to serve the content of the login page instead of the combined scripts, hence the error. To solve it - add a <location> section to the application configuration file to allow access to Telerik.Web.UI.WebResource.axd to all users, like: <configuration> ... <location path="Telerik.Web.UI.WebResource.axd"> <system.web> <authorization> <allow users="*"/> </authorization> </system.web> </location> ... </configuration>   Note that the access to the standard ScriptResource.axd and WebResource.axd is automatically allowed for all users (authenticated and unauthenticated), so if you use the ScriptManager instead of RadScriptManager - you will not face this problem. The authentication problem does not manifest when you disable script combining or use the CDN. Adding the above configuration section will make it work with RadScriptManagers combined script.   3. The IE6 browser fails to load the compressed script. The problem does not appear in any other browser. There is a well known bug in the older versions of IE6 which lose the first 2,048 bytes of data that are sent back from a Web server that uses HTTP compression. Latest versions of RadScriptManager does not compress the output at all if the client is IE6, but in the previous versions you need to manually disable the output compression to prevent the error. So, if you get the Sys is undefined error in IE6 - update to the latest version of RadControls or simply disable the output compression.   4. Requests to the *.axd files returns Error Code 404 - Not Found. This could  be fixed easily: Check in the IIS management console that the .axd extension (the default HTTP handler extension) is allowed:     Also check if the Verify if file exists checkbox is unchecked (click on the Edit button appearing in the previous screenshot to check). More information can be found in our troubleshooting article and from the ASP.NET QA team blog post   5. The virtual directory in IIS is not marked as Web Application. Converting it to Web Application should fix the problem.   6. Check for the <xhtmlConformance mode="Legacy"/> option in your web.config and remove it. It would be rather rare to become a victim of this exact case, but still have it in mind. Scott Guthrie describes it in more details   In the above points I mentioned several times the terms web resources, javascript output, compressed script. If you want to find out more about these please see the Web Resources Demystified series of my friend and colleague Atanas Korchev   I hope that one of the above solutions will help you get rid of the Sys is undefined error.   Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Mousin' down the PathListBox

  - by T

  While modifying the standard media player with a new look and feel for Ineta Live I saw a unique opportunity to use their logo with a dotted I with and attached arc as the scrub control. So I created a PathListBox that I wanted an object to follow when a user did a click and drag action.  Below is how I solved the problem.  Please let me know if you have improvements or know of a completely different way.  I am always eager to learn. First, I created a path using the pen tool in Expression Blend (see the yellow line in image below).  Then I right clicked that path and chose [Path] --> [Make Layout Path].   That created a new PathListBox.  Then I chose the object I want to move down the new PathListBox and Placed it as a child in the Objects and Timeline window (see image below).  If the child object (the thing the user will click and drag) is XAML, it will move much smoother than images. Just as another side note, I wanted there to be no highlight when the user selects the “ball” to drag and drop.  This is done by editing the ItemContainerStyle under Additional Templates on the PathListBox.  Post a question if you need help on this and I will expand my explanation. Here is a pic of the object and the path I wanted it to follow.  I gave the path a yellow solid brush here so you could see it but when I lay this over another object, I will make the path transparent.   To animate this object down the path, the trick is to animate the Start number for the LayoutPath.  Not the StartItemIndex, the Start above Span. In order to enable animation when a user clicks and drags, I put in the following code snippets in the code behind. the DependencyProperties are not necessary for the Drag control.   namespace InetaPlayer { public partial class PositionControl : UserControl { private bool _mouseDown; private double _maxPlayTime; public PositionControl() { // Required to initialize variables InitializeComponent(); //mouse events for scrub control positionThumb.MouseLeftButtonDown += new MouseButtonEventHandler(ValueThumb_MouseLeftButtonDown); positionThumb.MouseLeftButtonUp += new MouseButtonEventHandler(ValueThumb_MouseLeftButtonUp); positionThumb.MouseMove += new MouseEventHandler(ValueThumb_MouseMove); positionThumb.LostMouseCapture += new MouseEventHandler(ValueThumb_LostMouseCapture); } // exposed for binding to real slider using a DependencyProperty enables animation, styling, binding, etc.... public double MaxPlayTime { get { return (double)GetValue(MaxPlayTimeProperty); } set { SetValue(MaxPlayTimeProperty, value); } } public static readonly DependencyProperty MaxPlayTimeProperty = DependencyProperty.Register("MaxPlayTime", typeof(double), typeof(PositionControl), null);   // exposed for binding to real slider using a DependencyProperty enables animation, styling, binding, etc....   public double CurrSliderValue { get { return (double)GetValue(CurrSliderValueProperty); } set { SetValue(CurrSliderValueProperty, value); } }   public static readonly DependencyProperty CurrSliderValueProperty = DependencyProperty.Register("CurrSliderValue", typeof(double), typeof(PositionControl), new PropertyMetadata(0.0, OnCurrSliderValuePropertyChanged));   private static void OnCurrSliderValuePropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { PositionControl control = d as PositionControl; control.OnCurrSliderValueChanged((double)e.OldValue, (double)e.NewValue); }   private void OnCurrSliderValueChanged(double oldValue, double newValue) { _maxPlayTime = (double) GetValue(MaxPlayTimeProperty); if (!_mouseDown) if (_maxPlayTime!=0) sliderPathListBox.LayoutPaths[0].Start = newValue / _maxPlayTime; else sliderPathListBox.LayoutPaths[0].Start = 0; }   //mouse control   void ValueThumb_MouseMove(object sender, MouseEventArgs e) { if (!_mouseDown) return; //get the offset of how far the drag has been //direction is handled automatically (offset will be negative for left move and positive for right move) Point mouseOff = e.GetPosition(positionThumb); //Divide the offset by 1000 for a smooth transition sliderPathListBox.LayoutPaths[0].Start +=mouseOff.X/1000; _maxPlayTime = (double)GetValue(MaxPlayTimeProperty); SetValue(CurrSliderValueProperty ,sliderPathListBox.LayoutPaths[0].Start*_maxPlayTime); }   void ValueThumb_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { _mouseDown = false; } void ValueThumb_LostMouseCapture(object sender, MouseEventArgs e) { _mouseDown = false; } void ValueThumb_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { _mouseDown = true; ((UIElement)positionThumb).CaptureMouse(); }   } }   I made this into a user control and exposed a couple of DependencyProperties in order to bind it to a standard Slider in the overall project.  This control is embedded into the standard Expression media player template and is used to replace the standard scrub bar.  When the player goes live, I will put a link here.

• How can I implement a database TableView like thing in C++?

  - by Industrial-antidepressant

  How can I implement a TableView like thing in C++? I want to emulating a tiny relation database like thing in C++. I have data tables, and I want to transform it somehow, so I need a TableView like class. I want filtering, sorting, freely add and remove items and transforming (ex. view as UPPERCASE and so on). The whole thing is inside a GUI application, so datatables and views are attached to a GUI (or HTML or something). So how can I identify an item in the view? How can I signal it when the table is changed? Is there some design pattern for this?

• Stumbling Through: Visual Studio 2010 (Part II)

  I would now like to expand a little on what I stumbled through in part I of my Visual Studio 2010 post and touch on a few other features of VS 2010.  Specifically, I want to generate some code based off of an Entity Framework model and tie it up to an actual data source.  Im not going to take the easy way and tie to a SQL Server data source, though, I will tie it to an XML data file instead.  Why?  Well, why not?  This is purely for learning, there are probably much better ways to get strongly-typed classes around XML but it will force us to go down a path less travelled and maybe learn a few things along the way.  Once we get this XML data and the means to interact with it, I will revisit data binding to this data in a WPF form and see if I cant get reading, adding, deleting, and updating working smoothly with minimal code.  To begin, I will use what was learned in the first part of this blog topic and draw out a data model for the MFL (My Football League) - I dont want the NFL to come down and sue me for using their name in this totally football-related article.  The data model looks as follows, with Teams having Players, and Players having a position and statistics for each season they played: Note that when making the associations between these entities, I was given the option to create the foreign key but I only chose to select this option for the association between Player and Position.  The reason for this is that I am picturing the XML that will contain this data to look somewhat like this: <MFL> <Position/> <Position/> <Position/> <Team>     <Player>         <Statistic/>     </Player> </Team> </MFL> Statistic will be under its associated Player node, and Player will be under its associated Team node no need to have an Id to reference it if we know it will always fall under its parent.  Position, however, is more of a lookup value that will not have any hierarchical relationship to the player.  In fact, the Position data itself may be in a completely different xml file (something Id like to play around with), so in any case, a player will need to reference the position by its Id. So now that we have a simple data model laid out, I would like to generate two things based on it:  A class for each entity with properties corresponding to each entity property An IO class with methods to get data for each entity, either all instances, by Id or by parent. Now my experience with code generation in the past has consisted of writing up little apps that use the code dom directly to regenerate code on demand (or using tools like CodeSmith).  Surely, there has got to be a more fun way to do this given that we are using the Entity Framework which already has built-in code generation for SQL Server support.  Lets start with that built-in stuff to give us a base to work off of.  Right click anywhere in the canvas of our model and select Add Code Generation Item: So just adding that code item seemed to do quite a bit towards what I was intending: It apparently generated a class for each entity, but also a whole ton more.  I mean a TON more.  Way too much complicated code was generated now that code is likely to be a black box anyway so it shouldnt matter, but we need to understand how to make this work the way we want it to work, so lets get ready to do some stumbling through that text template (tt) file. When I open the .tt file that was generated, right off the bat I realize there is going to be trouble there is no color coding, no intellisense no nothing!  That is going to make stumbling through more like groping blindly in the dark while handcuffed and hopping on one foot, which was one of the alternate titles I was considering for this blog.  Thankfully, the community comes to my rescue and I wont have to cast my mind back to the glory days of coding in VI (look it up, kids).  Using the Extension Manager (Available under the Tools menu), I did a quick search for tt editor in the Online Gallery and quickly found the Tangible T4 Editor: Downloading and installing this was a breeze, and after doing so I got some color coding and intellisense while editing the tt files.  If you will be doing any customizing of tt files, I highly recommend installing this extension.  Next, well see if that is enough help for us to tweak that tt file to do the kind of code generation that we wantDid 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.

• Mousin' down the PathListBox

  - by T

  While modifying the standard media player with a new look and feel for Ineta Live I saw a unique opportunity to use their logo with a dotted I with and attached arc as the scrub control. So I created a PathListBox that I wanted an object to follow when a user did a click and drag action.  Below is how I solved the problem.  Please let me know if you have improvements or know of a completely different way.  I am always eager to learn. First, I created a path using the pen tool in Expression Blend (see the yellow line in image below).  Then I right clicked that path and chose [Path] --> [Make Layout Path].   That created a new PathListBox.  Then I chose the object I want to move down the new PathListBox and Placed it as a child in the Objects and Timeline window (see image below).  If the child object (the thing the user will click and drag) is XAML, it will move much smoother than images. Just as another side note, I wanted there to be no highlight when the user selects the “ball” to drag and drop.  This is done by editing the ItemContainerStyle under Additional Templates on the PathListBox.  Post a question if you need help on this and I will expand my explanation. Here is a pic of the object and the path I wanted it to follow.  I gave the path a yellow solid brush here so you could see it but when I lay this over another object, I will make the path transparent.   To animate this object down the path, the trick is to animate the Start number for the LayoutPath.  Not the StartItemIndex, the Start above Span. In order to enable animation when a user clicks and drags, I put in the following code snippets in the code behind. the DependencyProperties are not necessary for the Drag control. namespace InetaPlayer{ public partial class PositionControl : UserControl { private bool _mouseDown; private double _maxPlayTime; public PositionControl() { // Required to initialize variables InitializeComponent(); //mouse events for scrub control positionThumb.MouseLeftButtonDown += new MouseButtonEventHandler(ValueThumb_MouseLeftButtonDown); positionThumb.MouseLeftButtonUp += new MouseButtonEventHandler(ValueThumb_MouseLeftButtonUp); positionThumb.MouseMove += new MouseEventHandler(ValueThumb_MouseMove); positionThumb.LostMouseCapture += new MouseEventHandler(ValueThumb_LostMouseCapture); } // exposed for binding to real slider using a DependencyProperty enables animation, styling, binding, etc.... public double MaxPlayTime { get { return (double)GetValue(MaxPlayTimeProperty); } set { SetValue(MaxPlayTimeProperty, value); } } public static readonly DependencyProperty MaxPlayTimeProperty = DependencyProperty.Register("MaxPlayTime", typeof(double), typeof(PositionControl), null);   // exposed for binding to real slider using a DependencyProperty enables animation, styling, binding, etc....   public double CurrSliderValue { get { return (double)GetValue(CurrSliderValueProperty); } set { SetValue(CurrSliderValueProperty, value); } }   public static readonly DependencyProperty CurrSliderValueProperty = DependencyProperty.Register("CurrSliderValue", typeof(double), typeof(PositionControl), new PropertyMetadata(0.0, OnCurrSliderValuePropertyChanged));   private static void OnCurrSliderValuePropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { PositionControl control = d as PositionControl; control.OnCurrSliderValueChanged((double)e.OldValue, (double)e.NewValue); }   private void OnCurrSliderValueChanged(double oldValue, double newValue) { _maxPlayTime = (double) GetValue(MaxPlayTimeProperty); if (!_mouseDown) if (_maxPlayTime!=0) sliderPathListBox.LayoutPaths[0].Start = newValue / _maxPlayTime; else sliderPathListBox.LayoutPaths[0].Start = 0; }  //mouse control   void ValueThumb_MouseMove(object sender, MouseEventArgs e) { if (!_mouseDown) return; //get the offset of how far the drag has been //direction is handled automatically (offset will be negative for left move and positive for right move) Point mouseOff = e.GetPosition(positionThumb); //Divide the offset by 1000 for a smooth transition sliderPathListBox.LayoutPaths[0].Start +=mouseOff.X/1000; _maxPlayTime = (double)GetValue(MaxPlayTimeProperty); SetValue(CurrSliderValueProperty ,sliderPathListBox.LayoutPaths[0].Start*_maxPlayTime); }   void ValueThumb_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { _mouseDown = false; } void ValueThumb_LostMouseCapture(object sender, MouseEventArgs e) { _mouseDown = false; } void ValueThumb_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { _mouseDown = true; ((UIElement)positionThumb).CaptureMouse(); }   }}  I made this into a user control and exposed a couple of DependencyProperties in order to bind it to a standard Slider in the overall project.  This control is embedded into the standard Expression media player template and is used to replace the standard scrub bar.  When the player goes live, I will put a link here.

• BIP 11g Dynamic SQL

  - by Tim Dexter

  Back in the 10g release, if you wanted something beyond the standard query for your report extract; you needed to break out your favorite text editor. You gotta love 'vi' and hate emacs, am I right? And get to building a data template, they were/are lovely to write, such fun ... not! Its not fun writing them by hand but, you do get to do some cool stuff around the data extract including dynamic SQL. By that I mean the ability to add content dynamically to your your query at runtime. With 11g, we spoiled you with a visual builder, no more vi or notepad sessions, a friendly drag and drop interface allowing you to build hierarchical data sets, calculated columns, summary columns, etc. You can still create the dynamic SQL statements, its not so well documented right now, in lieu of doc updates here's the skinny. If you check out the 10g process to create dynamic sql in the docs. You need to create a data trigger function where you assign the dynamic sql to a global variable that's matched in your report SQL. In 11g, the process is really the same, BI Publisher just provides a bit more help to define what trigger code needs to be called. You still need to create the function and place it inside a package in the db. Here's a simple plsql package with the 'beforedata' function trigger. Spec create or replace PACKAGE BIREPORTS AS whereCols varchar2(2000); FUNCTION beforeReportTrig return boolean; end BIREPORTS; Body create or replace PACKAGE BODY BIREPORTS AS   FUNCTION beforeReportTrig return boolean AS   BEGIN       whereCols := ' and d.department_id = 100';     RETURN true;   END beforeReportTrig; END BIREPORTS; you'll notice the additional where clause (whereCols - declared as a public variable) is hard coded. I'll cover parameterizing that in my next post. If you can not wait, check the 10g docs for an example. I have my package compiling successfully in the db. Now, onto the BIP data model definition. 1. Create a new data model and go ahead and create your query(s) as you would normally. 2. In the query dialog box, add in the variables you want replaced at runtime using an ampersand rather than a colon e.g. &whereCols.   select     d.DEPARTMENT_NAME, ...  from    "OE"."EMPLOYEES" e,     "OE"."DEPARTMENTS" d  where   d."DEPARTMENT_ID"= e."DEPARTMENT_ID" &whereCols   Note that 'whereCols' matches the global variable name in our package. When you click OK to clear the dialog, you'll be asked for a default value for the variable, just use ' and 1=1' That leading space is important to keep the SQL valid ie required whitespace. This value will be used for the where clause if case its not set by the function code. 3. Now click on the Event Triggers tree node and create a new trigger of the type Before Data. Type in the default package name, in my example, 'BIREPORTS'. Then hit the update button to get BIP to fetch the valid functions.In my case I get to see the following: Select the BEFOREREPORTTRIG function (or your name) and shuttle it across. 4. Save your data model and now test it. For now, you can update the where clause via the plsql package. Next time ... parametrizing the dynamic clause.

• WPF TreeView MouseDown

  - by imekon

  I've got something like this in a TreeView: <DataTemplate x:Key="myTemplate"> <StackPanel MouseDown="OnItemMouseDown"> ... </StackPanel> </DataTemplate> Using this I get the mouse down events if I click on items in the stack panel. However... there seems to be another item behind the stack panel that is the TreeViewItem - it's very hard to hit, but not impossible, and that's when the problems start to occur. I had a go at handling PreviewMouseDown on TreeViewItem, however that seems to require e.Handled = false otherwise standard tree view behaviour stops working. Ok, Here's the source code...

• marshal data too short!!!

  - by Nitin Garg

  My application requires to keep large data objects in session. There are like 3-4 data objects each created by parsing a csv containing 150 X 20 cells having strings of 3-4 characters. My application shows this error- "marshal data too short". I tried this- Deleting the old session table. Deleting the old migration for session table. Creating a new migration using rake db: sessions:create. editing the migration manually, changing "text: data" to "longtext: data". running the migration using rake db: migrate. now when i open my application, i see this page- link text please someone help me, this is getting on my nerves!! other details of application-- In view "index.html.erb"- There is a link that makes ajax call to an action in controller, that action parses large csv file and makes an object out of it. this object is stored in session.

• Drupal views pane content not visible

• JBoss Seam: In ScopeType.PAGE I get: java.lang.IllegalStateException: No conversation context active

  - by Markos Fragkakis

  Hi all, I have a page-scoped component, which has an instance variable List with data, which I display in a datatable. This datatable has pagination, sorting and filtering. The first time gate into the page, I get this appended in my URL: ?conversationId=97. The page works correctly, and when I change datatable pages no now component is created. After a minute or two, and at seamingly random time, I get an exception saying that there is no context. I have not used @Create in my code or my navigation files. So, I have two questions: Why do I get this suffix in my URL? Why did a conversation start? Why the exception? The component is scoped to PAGE. If I received an exception, it should not be related to a conversation. Right? Or is the conversation the exception is referring a temporary conversation? Cheers!

• Help with Boost Grammar

  - by Decmanc04

  I have been using the following win32 console code to try to parse a B Machine Grammar embedded within C++ using Boost Spirit grammar template. I am a relatively new Boost user. The code compiles, but when I run the .exe file produced by VC++2008, the program partially parses the input file. I believe the problem is with my grammar definition or the functions attached as semantic atctions. The code is given below: // BIFAnalyser.cpp : Defines the entry point for the console application. // // /*============================================================================= Copyright (c) Temitope Jos Onunkun 2010 http://www.dcs.kcl.ac.uk/pg/onun/ Use, modification and distribution is subject to the Boost Software License, Version 1.0.

• Sensible Way to Pass Web Data in XML to a SQL Server Database

  - by Emtucifor

  After exploring several different ways to pass web data to a database for update purposes, I'm wondering if XML might be a good strategy. The database is currently SQL 2000. In a few months it will move to SQL 2005 and I will be able to change things if needed, but I need a SQL 2000 solution now. First of all, the database in question uses the EAV model. I know that this kind of database is generally highly frowned on, so for the purposes of this question, please just accept that this is not going to change. The current update method has the web server inserting values (that have all been converted first to their correct underlying types, then to sql_variant) to a temp table. A stored procedure is then run which expects the temp table to exist and it takes care of updating, inserting, or deleting things as needed. So far, only a single element has needed to be updated at a time. But now, there is a requirement to be able to edit multiple elements at once, and also to support hierarchical elements, each of which can have its own list of attributes. Here's some example XML I hand-typed to demonstrate what I'm thinking of. Note that in this database the Entity is Element and an ID of 0 signifies "create" aka an insert of a new item. <Elements> <Element ID="1234"> <Attr ID="221">Value</Attr> <Attr ID="225">287</Attr> <Attr ID="234"> <Element ID="99825"> <Attr ID="7">Value1</Attr> <Attr ID="8">Value2</Attr> <Attr ID="9" Action="delete" /> </Element> <Element ID="99826" Action="delete" /> <Element ID="0" Type="24"> <Attr ID="7">Value4</Attr> <Attr ID="8">Value5</Attr> <Attr ID="9">Value6</Attr> </Element> <Element ID="0" Type="24"> <Attr ID="7">Value7</Attr> <Attr ID="8">Value8</Attr> <Attr ID="9">Value9</Attr> </Element> </Attr> <Rel ID="3827" Action="delete" /> <Rel ID="2284" Role="parent"> <Element ID="3827" /> <Element ID="3829" /> <Attr ID="665">1</Attr> </Rel> <Rel ID="0" Type="23" Role="child"> <Element ID="3830" /> <Attr ID="67" </Rel> </Element> <Element ID="0" Type="87"> <Attr ID="221">Value</Attr> <Attr ID="225">569</Attr> <Attr ID="234"> <Element ID="0" Type="24"> <Attr ID="7">Value10</Attr> <Attr ID="8">Value11</Attr> <Attr ID="9">Value12</Attr> </Element> </Attr> </Element> <Element ID="1235" Action="delete" /> </Elements> Some Attributes are straight value types, such as AttrID 221. But AttrID 234 is a special "multi-value" type that can have a list of elements underneath it, and each one can have one or more values. Types only need to be presented when a new item is created, since the ElementID fully implies the type if it already exists. I'll probably support only passing in changed items (as detected by javascript). And there may be an Action="Delete" on Attr elements as well, since NULLs are treated as "unselected"--sometimes it's very important to know if a Yes/No question has intentionally been answered No or if no one's bothered to say Yes yet. There is also a different kind of data, a Relationship. At this time, those are updated through individual AJAX calls as things are edited in the UI, but I'd like to include those so that changes to relationships can be canceled (right now, once you change it, it's done). So those are really elements, too, but they are called Rel instead of Element. Relationships are implemented as ElementID1 and ElementID2, so the RelID 2284 in the XML above is in the database as: ElementID 2284 ElementID1 1234 ElementID2 3827 Having multiple children in one relationship isn't currently supported, but it would be nice later. Does this strategy and the example XML make sense? Is there a more sensible way? I'm just looking for some broad critique to help save me from going down a bad path. Any aspect that you'd like to comment on would be helpful. The web language happens to be Classic ASP, but that could change to ASP.Net at some point. A persistence engine like Linq or nHibernate is probably not acceptable right now--I just want to get this already working application enhanced without a huge amount of development time. I'll choose the answer that shows experience and has a balance of good warnings about what not to do, confirmations of what I'm planning to do, and recommendations about something else to do. I'll make it as objective as possible. P.S. I'd like to handle unicode characters as well as very long strings (10k +). UPDATE I have had this working for some time and I used the ADO Recordset Save-To-Stream trick to make creating the XML really easy. The result seems to be fairly fast, though if speed ever becomes a problem I may revisit this. In the meantime, my code works to handle any number of elements and attributes on the page at once, including updating, deleting, and creating new items all in one go. I settled on a scheme like so for all my elements: Existing data elements Example: input name e12345_a678 (element 12345, attribute 678), the input value is the value of the attribute. New elements Javascript copies a hidden template of the set of HTML elements needed for the type into the correct location on the page, increments a counter to get a new ID for this item, and prepends the number to the names of the form items. var newid = 0; function metadataAdd(reference, nameid, value) { var t = document.createElement('input'); t.setAttribute('name', nameid); t.setAttribute('id', nameid); t.setAttribute('type', 'hidden'); t.setAttribute('value', value); reference.appendChild(t); } function multiAdd(target, parentelementid, attrid, elementtypeid) { var proto = document.getElementById('a' + attrid + '_proto'); var instance = document.createElement('p'); target.parentNode.parentNode.insertBefore(instance, target.parentNode); var thisid = ++newid; instance.innerHTML = proto.innerHTML.replace(/{prefix}/g, 'n' + thisid + '_'); instance.id = 'n' + thisid; instance.className += ' new'; metadataAdd(instance, 'n' + thisid + '_p', parentelementid); metadataAdd(instance, 'n' + thisid + '_c', attrid); metadataAdd(instance, 'n' + thisid + '_t', elementtypeid); return false; } Example: Template input name _a678 becomes n1_a678 (a new element, the first one on the page, attribute 678). all attributes of this new element are tagged with the same prefix of n1. The next new item will be n2, and so on. Some hidden form inputs are created: n1_t, value is the elementtype of the element to be created n1_p, value is the parent id of the element (if it is a relationship) n1_c, value is the child id of the element (if it is a relationship) Deleting elements A hidden input is created in the form e12345_t with value set to 0. The existing controls displaying that attribute's values are disabled so they are not included in the form post. So "set type to 0" is treated as delete. With this scheme, every item on the page has a unique name and can be distinguished properly, and every action can be represented properly. When the form is posted, here's a sample of building one of the two recordsets used (classic ASP code): Set Data = Server.CreateObject("ADODB.Recordset") Data.Fields.Append "ElementID", adInteger, 4, adFldKeyColumn Data.Fields.Append "AttrID", adInteger, 4, adFldKeyColumn Data.Fields.Append "Value", adLongVarWChar, 2147483647, adFldIsNullable Or adFldMayBeNull Data.CursorLocation = adUseClient Data.CursorType = adOpenDynamic Data.Open This is the recordset for values, the other is for the elements themselves. I step through the posted form and for the element recordset use a Scripting.Dictionary populated with instances of a custom Class that has the properties I need, so that I can add the values piecemeal, since they don't always come in order. New elements are added as negative to distinguish them from regular elements (rather than requiring a separate column to indicate if it is new or addresses an existing element). I use regular expression to tear apart the form keys: "^(e|n)([0-9]{1,10})_(a|p|t|c)([0-9]{0,10})$" Then, adding an attribute looks like this. Data.AddNew ElementID.Value = DataID AttrID.Value = Integerize(Matches(0).SubMatches(3)) AttrValue.Value = Request.Form(Key) Data.Update ElementID, AttrID, and AttrValue are references to the fields of the recordset. This method is hugely faster than using Data.Fields("ElementID").Value each time. I loop through the Dictionary of element updates and ignore any that don't have all the proper information, adding the good ones to the recordset. Then I call my data-updating stored procedure like so: Set Cmd = Server.CreateObject("ADODB.Command") With Cmd Set .ActiveConnection = MyDBConn .CommandType = adCmdStoredProc .CommandText = "DataPost" .Prepared = False .Parameters.Append .CreateParameter("@ElementMetadata", adLongVarWChar, adParamInput, 2147483647, XMLFromRecordset(Element)) .Parameters.Append .CreateParameter("@ElementData", adLongVarWChar, adParamInput, 2147483647, XMLFromRecordset(Data)) End With Result.Open Cmd ' previously created recordset object with options set Here's the function that does the xml conversion: Private Function XMLFromRecordset(Recordset) Dim Stream Set Stream = Server.CreateObject("ADODB.Stream") Stream.Open Recordset.Save Stream, adPersistXML Stream.Position = 0 XMLFromRecordset = Stream.ReadText End Function Just in case the web page needs to know, the SP returns a recordset of any new elements, showing their page value and their created value (so I can see that n1 is now e12346 for example). Here are some key snippets from the stored procedure. Note this is SQL 2000 for now, though I'll be able to switch to 2005 soon: CREATE PROCEDURE [dbo].[DataPost] @ElementMetaData ntext, @ElementData ntext AS DECLARE @hdoc int --- snip --- EXEC sp_xml_preparedocument @hdoc OUTPUT, @ElementMetaData, '<xml xmlns:s="uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882" xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882" xmlns:rs="urn:schemas-microsoft-com:rowset" xmlns:z="#RowsetSchema" />' INSERT #ElementMetadata (ElementID, ElementTypeID, ElementID1, ElementID2) SELECT * FROM OPENXML(@hdoc, '/xml/rs:data/rs:insert/z:row', 0) WITH ( ElementID int, ElementTypeID int, ElementID1 int, ElementID2 int ) ORDER BY ElementID -- orders negative items (new elements) first so they begin counting at 1 for later ID calculation EXEC sp_xml_removedocument @hdoc --- snip --- UPDATE E SET E.ElementTypeID = M.ElementTypeID FROM Element E INNER JOIN #ElementMetadata M ON E.ElementID = M.ElementID WHERE E.ElementID >= 1 AND M.ElementTypeID >= 1 The following query does the correlation of the negative new element ids to the newly inserted ones: UPDATE #ElementMetadata -- Correlate the new ElementIDs with the input rows SET NewElementID = Scope_Identity() - @@RowCount + DataID WHERE ElementID < 0 Other set-based queries do all the other work of validating that the attributes are allowed, are the correct data type, and inserting, updating, and deleting elements and attributes. I hope this brief run-down is useful to others some day! Converting ADO Recordsets to an XML stream was a huge winner for me as it saved all sorts of time and had a namespace and schema already defined that made the results come out correctly. Using a flatter XML format with 2 inputs was also much easier than sticking to some ideal about having everything in a single XML stream.

• Sensible Way to Pass Web Data to Sql Server Database

  - by Emtucifor

  After exploring several different ways to pass web data to a database for update purposes, I'm wondering if XML might be a good strategy. The database is currently SQL 2000. In a few months it will move to SQL 2005 and I will be able to change things if needed, but I need a SQL 2000 solution now. First of all, the database in question uses the EAV model. I know that this kind of database is generally highly frowned on, so for the purposes of this question, please just accept that this is not going to change. The current update method has the web server inserting values (that have all been converted first to their correct underlying types, then to sql_variant) to a temp table. A stored procedure is then run which expects the temp table to exist and it takes care of updating, inserting, or deleting things as needed. So far, only a single element has needed to be updated at a time. But now, there is a requirement to be able to edit multiple elements at once, and also to support hierarchical elements, each of which can have its own list of attributes. Here's some example XML I hand-typed to demonstrate what I'm thinking of. Note that in this database the Entity is Element and an ID of 0 signifies "create" aka an insert of a new item. <Elements> <Element ID="1234"> <Attr ID="221">Value</Attr> <Attr ID="225">287</Attr> <Attr ID="234"> <Element ID="99825"> <Attr ID="7">Value1</Attr> <Attr ID="8">Value2</Attr> <Attr ID="9" Action="delete" /> </Element> <Element ID="99826" Action="delete" /> <Element ID="0" Type="24"> <Attr ID="7">Value4</Attr> <Attr ID="8">Value5</Attr> <Attr ID="9">Value6</Attr> </Element> <Element ID="0" Type="24"> <Attr ID="7">Value7</Attr> <Attr ID="8">Value8</Attr> <Attr ID="9">Value9</Attr> </Element> </Attr> <Rel ID="3827" Action="delete" /> <Rel ID="2284" Role="parent"> <Element ID="3827" /> <Element ID="3829" /> <Attr ID="665">1</Attr> </Rel> <Rel ID="0" Type="23" Role="child"> <Element ID="3830" /> <Attr ID="67" </Rel> </Element> <Element ID="0" Type="87"> <Attr ID="221">Value</Attr> <Attr ID="225">569</Attr> <Attr ID="234"> <Element ID="0" Type="24"> <Attr ID="7">Value10</Attr> <Attr ID="8">Value11</Attr> <Attr ID="9">Value12</Attr> </Element> </Attr> </Element> <Element ID="1235" Action="delete" /> </Elements> Some Attributes are straight value types, such as AttrID 221. But AttrID 234 is a special "multi-value" type that can have a list of elements underneath it, and each one can have one or more values. Types only need to be presented when a new item is created, since the ElementID fully implies the type if it already exists. I'll probably support only passing in changed items (as detected by javascript). And there may be an Action="Delete" on Attr elements as well, since NULLs are treated as "unselected"--sometimes it's very important to know if a Yes/No question has intentionally been answered No or if no one's bothered to say Yes yet. There is also a different kind of data, a Relationship. At this time, those are updated through individual AJAX calls as things are edited in the UI, but I'd like to include those so that changes to relationships can be canceled (right now, once you change it, it's done). So those are really elements, too, but they are called Rel instead of Element. Relationships are implemented as ElementID1 and ElementID2, so the RelID 2284 in the XML above is in the database as: ElementID 2284 ElementID1 1234 ElementID2 3827 Having multiple children in one relationship isn't currently supported, but it would be nice later. Does this strategy and the example XML make sense? Is there a more sensible way? I'm just looking for some broad critique to help save me from going down a bad path. Any aspect that you'd like to comment on would be helpful. The web language happens to be Classic ASP, but that could change to ASP.Net at some point. A persistence engine like Linq or nHibernate is probably not acceptable right now--I just want to get this already working application enhanced without a huge amount of development time. I'll choose the answer that shows experience and has a balance of good warnings about what not to do, confirmations of what I'm planning to do, and recommendations about something else to do. I'll make it as objective as possible. P.S. I'd like to handle unicode characters as well as very long strings (10k +). UPDATE I have had this working for some time and I used the ADO Recordset Save-To-Stream trick to make creating the XML really easy. The result seems to be fairly fast, though if speed ever becomes a problem I may revisit this. In the meantime, my code works to handle any number of elements and attributes on the page at once, including updating, deleting, and creating new items all in one go. I settled on a scheme like so for all my elements: Existing data elements Example: input name e12345_a678 (element 12345, attribute 678), the input value is the value of the attribute. New elements Javascript copies a hidden template of the set of HTML elements needed for the type into the correct location on the page, increments a counter to get a new ID for this item, and prepends the number to the names of the form items. var newid = 0; function metadataAdd(reference, nameid, value) { var t = document.createElement('input'); t.setAttribute('name', nameid); t.setAttribute('id', nameid); t.setAttribute('type', 'hidden'); t.setAttribute('value', value); reference.appendChild(t); } function multiAdd(target, parentelementid, attrid, elementtypeid) { var proto = document.getElementById('a' + attrid + '_proto'); var instance = document.createElement('p'); target.parentNode.parentNode.insertBefore(instance, target.parentNode); var thisid = ++newid; instance.innerHTML = proto.innerHTML.replace(/{prefix}/g, 'n' + thisid + '_'); instance.id = 'n' + thisid; instance.className += ' new'; metadataAdd(instance, 'n' + thisid + '_p', parentelementid); metadataAdd(instance, 'n' + thisid + '_c', attrid); metadataAdd(instance, 'n' + thisid + '_t', elementtypeid); return false; } Example: Template input name _a678 becomes n1_a678 (a new element, the first one on the page, attribute 678). all attributes of this new element are tagged with the same prefix of n1. The next new item will be n2, and so on. Some hidden form inputs are created: n1_t, value is the elementtype of the element to be created n1_p, value is the parent id of the element (if it is a relationship) n1_c, value is the child id of the element (if it is a relationship) Deleting elements A hidden input is created in the form e12345_t with value set to 0. The existing controls displaying that attribute's values are disabled so they are not included in the form post. So "set type to 0" is treated as delete. With this scheme, every item on the page has a unique name and can be distinguished properly, and every action can be represented properly. When the form is posted, here's a sample of building one of the two recordsets used (classic ASP code): Set Data = Server.CreateObject("ADODB.Recordset") Data.Fields.Append "ElementID", adInteger, 4, adFldKeyColumn Data.Fields.Append "AttrID", adInteger, 4, adFldKeyColumn Data.Fields.Append "Value", adLongVarWChar, 2147483647, adFldIsNullable Or adFldMayBeNull Data.CursorLocation = adUseClient Data.CursorType = adOpenDynamic Data.Open This is the recordset for values, the other is for the elements themselves. I step through the posted form and for the element recordset use a Scripting.Dictionary populated with instances of a custom Class that has the properties I need, so that I can add the values piecemeal, since they don't always come in order. New elements are added as negative to distinguish them from regular elements (rather than requiring a separate column to indicate if it is new or addresses an existing element). I use regular expression to tear apart the form keys: "^(e|n)([0-9]{1,10})_(a|p|t|c)([0-9]{0,10})$" Then, adding an attribute looks like this. Data.AddNew ElementID.Value = DataID AttrID.Value = Integerize(Matches(0).SubMatches(3)) AttrValue.Value = Request.Form(Key) Data.Update ElementID, AttrID, and AttrValue are references to the fields of the recordset. This method is hugely faster than using Data.Fields("ElementID").Value each time. I loop through the Dictionary of element updates and ignore any that don't have all the proper information, adding the good ones to the recordset. Then I call my data-updating stored procedure like so: Set Cmd = Server.CreateObject("ADODB.Command") With Cmd Set .ActiveConnection = MyDBConn .CommandType = adCmdStoredProc .CommandText = "DataPost" .Prepared = False .Parameters.Append .CreateParameter("@ElementMetadata", adLongVarWChar, adParamInput, 2147483647, XMLFromRecordset(Element)) .Parameters.Append .CreateParameter("@ElementData", adLongVarWChar, adParamInput, 2147483647, XMLFromRecordset(Data)) End With Result.Open Cmd ' previously created recordset object with options set Here's the function that does the xml conversion: Private Function XMLFromRecordset(Recordset) Dim Stream Set Stream = Server.CreateObject("ADODB.Stream") Stream.Open Recordset.Save Stream, adPersistXML Stream.Position = 0 XMLFromRecordset = Stream.ReadText End Function Just in case the web page needs to know, the SP returns a recordset of any new elements, showing their page value and their created value (so I can see that n1 is now e12346 for example). Here are some key snippets from the stored procedure. Note this is SQL 2000 for now, though I'll be able to switch to 2005 soon: CREATE PROCEDURE [dbo].[DataPost] @ElementMetaData ntext, @ElementData ntext AS DECLARE @hdoc int --- snip --- EXEC sp_xml_preparedocument @hdoc OUTPUT, @ElementMetaData, '<xml xmlns:s="uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882" xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882" xmlns:rs="urn:schemas-microsoft-com:rowset" xmlns:z="#RowsetSchema" />' INSERT #ElementMetadata (ElementID, ElementTypeID, ElementID1, ElementID2) SELECT * FROM OPENXML(@hdoc, '/xml/rs:data/rs:insert/z:row', 0) WITH ( ElementID int, ElementTypeID int, ElementID1 int, ElementID2 int ) ORDER BY ElementID -- orders negative items (new elements) first so they begin counting at 1 for later ID calculation EXEC sp_xml_removedocument @hdoc --- snip --- UPDATE E SET E.ElementTypeID = M.ElementTypeID FROM Element E INNER JOIN #ElementMetadata M ON E.ElementID = M.ElementID WHERE E.ElementID >= 1 AND M.ElementTypeID >= 1 The following query does the correlation of the negative new element ids to the newly inserted ones: UPDATE #ElementMetadata -- Correlate the new ElementIDs with the input rows SET NewElementID = Scope_Identity() - @@RowCount + DataID WHERE ElementID < 0 Other set-based queries do all the other work of validating that the attributes are allowed, are the correct data type, and inserting, updating, and deleting elements and attributes. I hope this brief run-down is useful to others some day! Converting ADO Recordsets to an XML stream was a huge winner for me as it saved all sorts of time and had a namespace and schema already defined that made the results come out correctly. Using a flatter XML format with 2 inputs was also much easier than sticking to some ideal about having everything in a single XML stream.

• ASP.Net MVC 2 DropDownListFor in EditorTemplate

  - by tschreck

  I have a view model that looks like this: namespace AutoForm.Models { public class ProductViewModel { [UIHint("DropDownList")] public String Category { get; set; } [ScaffoldColumn(false)] public IEnumerable<SelectListItem> CategoryList { get; set; } ... } } It has Category and CategoryList properties. The CategoryList is the source data for the Category dropdown UI element. I have an EditorTemplate that looks like this: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ProductViewModel>" %> <%@ Import Namespace="AutoForm.Models"%> <%=Html.DropDownListFor(m => m.Category , Model.CategoryList ) %> NOTE: this EditorTemplate is strongly typed to ProductViewModel My Controller is populating CategoryList property with data from a database. I cannot get the DropDownListFor template to render a drop down list with data from CategoryList. I know CategoryList is getting populated with data in the controller because I see the data when I debug and step through the controller. Here's my error message in the browser: Server Error in '/' Application. Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Source Error: Line 2: <%@ Import Namespace="AutoForm.Models"% Line 3: Line 4: <%=Html.DropDownListFor(m = m.Category, Model.CategoryList) % Source File: c:\ProjectStore\AutoForm\AutoForm\Views\Shared\EditorTemplates\DropDownList.ascx Line: 4 Any ideas? Thanks Tom As a followup, I noticed that ViewData.Model is null when I'm stepping through the code in the EditorTemplate. I have the EditorTemplate strongly typed to "ProductViewModel" which is also the type that's passed to the View in the controller. I'm perplexed as to why ViewData.Model is null even though it's getting populated in the controller before getting passed to the view.

• WPF - ListView within listView Scrollbar problem

  - by Josh

  So I currently have a ListView "List A" who's items each have an expander control which contains another ListView "List B". The problem I am having is that sometimes List B grows so big that it extends beyond the range of List A's view area. List A's scroll bars do not pick up the fact that parts of List B are not being displayed. Is there a way to setup my xaml so that the scroll bars for List A will detect when the list inside the expander is longer then the viewing area of List A. Here is the section of code I need to modify: <TabItem Header="Finished"> <TabItem.Resources> <ResourceDictionary> <DataTemplate x:Key="EpisodeItem"> <DockPanel Margin="30,3"> <TextBlock Text="{Binding Title}" DockPanel.Dock="Left" /> <WrapPanel Margin="10,0" DockPanel.Dock="Right"> <TextBlock Text="Finished at: " /> <TextBlock Text="{Binding TimeAdded}" /> </WrapPanel> </DockPanel> </DataTemplate> <DataTemplate x:Key="AnimeItem"> <DockPanel Margin="5,10"> <Image Height="75" Width="Auto" Source="{Binding ImagePath}" DockPanel.Dock="Left" VerticalAlignment="Top"/> <Expander Template="{StaticResource AnimeExpanderControlTemplate}" > <Expander.Header> <TextBlock FontWeight="Bold" Text="{Binding AnimeTitle}" /> </Expander.Header> <ListView ItemsSource="{Binding Episodes}" ItemTemplate="{StaticResource EpisodeItem}" BorderThickness="0,0,0,0" /> </Expander> </DockPanel> </DataTemplate> </ResourceDictionary> </TabItem.Resources> <ListView Name="finishedView" ItemsSource="{Binding UploadedAnime, diagnostics:PresentationTraceSources.TraceLevel=High}" ItemTemplate="{StaticResource AnimeItem}" /> </TabItem> List A is the ListView with name "finishedView" and List B is the ListView with ItemSource "Episodes"

• WPF DataGrid binding to UserControl

  - by Trindaz

  I have a DataGrid with one column using a UserControl via a styled DataGridTemplateColumn. I can't seem to get the UserControl to 'see' the object that is in it's containing DataGridCell though. What kind of bindings can I create on the TextBox in my UserControl so that it can look up and see that object?! My UserControl and TemplateColumn Style are defined as: <Window.Resources> <local:UCTest x:Key="UCTest" /> <Style x:Key="TestStyle" TargetType="{x:Type WpfToolkit:DataGridCell}"> <Style.Setters> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type WpfToolkit:DataGridCell}"> <Grid Background="{Binding RelativeSource={RelativeSource TemplatedParent}, Converter={StaticResource drc}, Path=DataContext}"> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <local:UCTest /> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style.Setters> </Style> </Window.Resources> and my sample DataGrid is defined as: <WpfToolkit:DataGrid Name="dgSampleData" ItemsSource="{Binding}" AutoGenerateColumns="True" Margin="0,75,0,0"> <WpfToolkit:DataGrid.Columns> <WpfToolkit:DataGridTemplateColumn Header="Col2" CellStyle="{StaticResource TestStyle}" /> </WpfToolkit:DataGrid.Columns> </WpfToolkit:DataGrid> and my User Control is defined in a separate file as: <UserControl x:Class="UCTest" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:local="clr-namespace:WpfApplication1" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="104" Height="51"> <UserControl.Resources> <local:DataRowConverter x:Key="drc" /> </UserControl.Resources> <Grid> <TextBox Margin="12,12,-155,16" Name="TextBox1" Text="" /> </Grid> EDIT: My implementation of TestClass, which has the Test Property, which I want UCTest.TextBox1 to bind do: Public Class TestClass Private _Test As String = "Hello World Property!" Public Property Test() As String Get Return _Test End Get Set(ByVal value As String) _Test = value End Set End Property End Class Thanks in advance!
