• Stack overflow in xp cmd console

  - by Dave

  I am using an older program whose source code I cannot see. I am using the cmd.exe console in windows xp. The program ran with no problems on an xp machine last year, while a stack overflow code 2000 error was observed on a different xp machine (easy fix - use the machine that works). I tried running the program on the previously working machine lately, and now am getting the same error. No changes to the os were made and I did not change the service pack version. Any ideas on how to get around this stack overflow error so I can use the program? Dosbox will at least open the program, however it does not run to completion. Thanks!

• why does absolute paths of images gets converted to cid?

  - by David Verhulst

  I've got mailings that need to be sended using cron. When I load the script manualy all works fine. With cron i get broken images. to change the src of my img i used: $body = eregi_replace("managersrc_logo","images/managers/acertainlogo.jpg",$body); Because i thaught that it is importent to use absolute paths i also tried: $body = eregi_replace("managersrc_logo","http://www.site.com/images/managers/acertainlogo.jpg",$body); In that case i even do not see the images when i run the cronscript manualy. Nor the automated cron will display me the images. When i check the source of the mail that is received i always see "cid:encryptedstuff" even if i use absolute paths? Why is that? I just want my absolute paths being printed in the src attribute of the img tag. Who changes my absolute path to cid: ? is it php, phpmailer or outlook itself? Any help someone?.... David

• Outlook 2003 add-in - Getting COM exception on application shutdown after creating WPF window

  - by Oliver Hanappi

  Hi! I'm developing an outlook 2003 add-in. Until now I used only winforms to display one form, but today I've added a WPF window for more complex stuff. DUe to the WPF window, a COM exception is being thrown when outlook shuts down. Does anybody know why? I need to start a separate thread for the WPF window in single apartment state. Here is the exception: System.Runtime.InteropServices.InvalidComObjectException was unhandled Message="COM object that has been separated from its underlying RCW cannot be used." Source="PresentationCore" StackTrace: at System.Windows.Input.TextServicesContext.StopTransitoryExtension() at System.Windows.Input.TextServicesContext.Uninitialize(Boolean appDomainShutdown) at System.Windows.Input.TextServicesContext.TextServicesContextShutDownListener.OnShutDown(Object target) at MS.Internal.ShutDownListener.HandleShutDown(Object sender, EventArgs e) InnerException: Best Regards, Oliver Hanappi

• Synchronize Data between a Silverlight ListBox and a User Control

  - by psheriff

  One of the great things about XAML is the powerful data-binding capabilities. If you load up a list box with a collection of objects, you can display detail data about each object without writing any C# or VB.NET code. Take a look at Figure 1 that shows a collection of Product objects in a list box. When you click on a list box you bind the current Product object selected in the list box to a set of controls in a user control with just a very simple Binding statement in XAML.  Figure 1: Synchronizing a ListBox to a User Control is easy with Data Binding Product and Products Classes To illustrate this data binding feature I am going to just create some local data instead of using a WCF service. The code below shows a Product class that has three properties, namely, ProductId, ProductName and Price. This class also has a constructor that takes 3 parameters and allows us to set the 3 properties in an instance of our Product class. C#public class Product{  public Product(int productId, string productName, decimal price)  {    ProductId = productId;    ProductName = productName;    Price = price;  }   public int ProductId { get; set; }  public string ProductName { get; set; }  public decimal Price { get; set; }} VBPublic Class Product  Public Sub New(ByVal _productId As Integer, _                 ByVal _productName As String, _                 ByVal _price As Decimal)    ProductId = _productId    ProductName = _productName    Price = _price  End Sub   Private mProductId As Integer  Private mProductName As String  Private mPrice As Decimal   Public Property ProductId() As Integer    Get      Return mProductId    End Get    Set(ByVal value As Integer)      mProductId = value    End Set  End Property   Public Property ProductName() As String    Get      Return mProductName    End Get    Set(ByVal value As String)      mProductName = value    End Set  End Property   Public Property Price() As Decimal    Get      Return mPrice    End Get    Set(ByVal value As Decimal)      mPrice = value    End Set  End PropertyEnd Class To fill up a list box you need a collection class of Product objects. The code below creates a generic collection class of Product objects. In the constructor of the Products class I have hard-coded five product objects and added them to the collection. In a real-world application you would get your data through a call to service to fill the list box, but for simplicity and just to illustrate the data binding, I am going to just hard code the data. C#public class Products : List<Product>{  public Products()  {    this.Add(new Product(1, "Microsoft VS.NET 2008", 1000));    this.Add(new Product(2, "Microsoft VS.NET 2010", 1000));    this.Add(new Product(3, "Microsoft Silverlight 4", 1000));    this.Add(new Product(4, "Fundamentals of N-Tier eBook", 20));    this.Add(new Product(5, "ASP.NET Security eBook", 20));  }} VBPublic Class Products  Inherits List(Of Product)   Public Sub New()    Me.Add(New Product(1, "Microsoft VS.NET 2008", 1000))    Me.Add(New Product(2, "Microsoft VS.NET 2010", 1000))    Me.Add(New Product(3, "Microsoft Silverlight 4", 1000))    Me.Add(New Product(4, "Fundamentals of N-Tier eBook", 20))    Me.Add(New Product(5, "ASP.NET Security eBook", 20))  End SubEnd Class The Product Detail User Control Below is a user control (named ucProduct) that is used to display the product detail information seen in the bottom portion of Figure 1. This is very basic XAML that just creates a text block and a text box control for each of the three properties in the Product class. Notice the {Binding Path=[PropertyName]} on each of the text box controls. This means that if the DataContext property of this user control is set to an instance of a Product class, then the data in the properties of that Product object will be displayed in each of the text boxes. <UserControl x:Class="SL_SyncListBoxAndUserControl_CS.ucProduct"  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  HorizontalAlignment="Left"  VerticalAlignment="Top">  <Grid Margin="4">    <Grid.RowDefinitions>      <RowDefinition Height="Auto" />      <RowDefinition Height="Auto" />      <RowDefinition Height="Auto" />    </Grid.RowDefinitions>    <Grid.ColumnDefinitions>      <ColumnDefinition MinWidth="120" />      <ColumnDefinition />    </Grid.ColumnDefinitions>    <TextBlock Grid.Row="0"               Grid.Column="0"               Text="Product Id" />    <TextBox Grid.Row="0"             Grid.Column="1"             Text="{Binding Path=ProductId}" />    <TextBlock Grid.Row="1"               Grid.Column="0"               Text="Product Name" />    <TextBox Grid.Row="1"             Grid.Column="1"             Text="{Binding Path=ProductName}" />    <TextBlock Grid.Row="2"               Grid.Column="0"               Text="Price" />    <TextBox Grid.Row="2"             Grid.Column="1"             Text="{Binding Path=Price}" />  </Grid></UserControl> Synchronize ListBox with User Control You are now ready to fill the list box with the collection class of Product objects and then bind the SelectedItem of the list box to the Product detail user control. The XAML below is the complete code for Figure 1. <UserControl x:Class="SL_SyncListBoxAndUserControl_CS.MainPage"  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  xmlns:src="clr-namespace:SL_SyncListBoxAndUserControl_CS"  VerticalAlignment="Top"  HorizontalAlignment="Left">  <UserControl.Resources>    <src:Products x:Key="productCollection" />  </UserControl.Resources>  <Grid x:Name="LayoutRoot"        Margin="4"        Background="White">    <Grid.RowDefinitions>      <RowDefinition Height="Auto" />      <RowDefinition Height="*" />    </Grid.RowDefinitions>    <ListBox x:Name="lstData"             Grid.Row="0"             BorderBrush="Black"             BorderThickness="1"             ItemsSource="{Binding                   Source={StaticResource productCollection}}"             DisplayMemberPath="ProductName" />    <src:ucProduct x:Name="prodDetail"                   Grid.Row="1"                   DataContext="{Binding ElementName=lstData,                                          Path=SelectedItem}" />  </Grid></UserControl> The first step to making this happen is to reference the Silverlight project (SL_SyncListBoxAndUserControl_CS) where the Product and Products classes are located. I added this namespace and assigned it a namespace prefix of “src” as shown in the line below: xmlns:src="clr-namespace:SL_SyncListBoxAndUserControl_CS" Next, to use the data from an instance of the Products collection, you create a UserControl.Resources section in the XAML and add a tag that creates an instance of the Products class and assigns it a key of “productCollection”.   <UserControl.Resources>    <src:Products x:Key="productCollection" />  </UserControl.Resources> Next, you bind the list box to this productCollection object using the ItemsSource property. You bind the ItemsSource of the list box to the static resource named productCollection. You can then set the DisplayMemberPath attribute of the list box to any property of the Product class that you want. In the XAML below I used the ProductName property. <ListBox x:Name="lstData"         ItemsSource="{Binding             Source={StaticResource productCollection}}"         DisplayMemberPath="ProductName" /> You now need to create an instance of the ucProduct user contol below the list box. You do this by once again referencing the “src” namespace and typing in the name of the user control. You then set the DataContext property on this user control to a binding. The binding uses the ElementName attribute to bind to the list box name, in this case “lstData”. The Path of the data is SelectedItem. These two attributes together tell Silverlight to bind the DataContext to the selected item of the list box. That selected item is a Product object. So, once this is bound, the bindings on each text box in the user control are updated and display the current product information. <src:ucProduct x:Name="prodDetail"               DataContext="{Binding ElementName=lstData,                                      Path=SelectedItem}" /> Summary Once you understand the basics of data binding in XAML, you eliminate a lot code that is otherwise needed to move data into controls and out of controls back into an object. Connecting two controls together is easy by just binding using the ElementName and Path properties of the Binding markup extension. Another good tip out of this blog is use user controls and set the DataContext of the user control to have all of the data on the user control update through the bindings.

• Could the HTML 5 Video tag pick up an IP Multicast Stream?

  - by DrewBarbs

  I've been researching methods of getting an IP Multicast over UDP to the browser, and have found little that suggests I would be able to do it without using a plug-in like Java, Flash, or Silverlight in order to open a UDP port and (somehow) render the video. Checking out the HTML 5 <video> spec, there is (obviously) little in the way of specific implementation details, so as far as I can tell, there is nothing stopping a browser from parsing a address of the form "udp://224.1.1.1:8000" and joining a multicast group on that IP/port. Is this a correct understanding? Or must the resource pointed to by the <source> be a file?

• Visual C# 2008 Express connection to SQL Server 2008 Express problem

  - by Phil

  Hi guys, I have a problem with Visual C# 2008 express (SP1) connecting to SQL Server 2008 express. The "Add Connection" window (wherever initiated) doesn't list existing sql server and no option for sql server except a compact edition. Note that, I've got the VWD 2008 express (SP1) on the same machine which shows the window regularly (with SQL server listed) and SQL Server Management studio works fine with the server as well. I've seen other similar posts, did take some advices: reinstalled the VC#, services run ok, etc... but with no success with VC# so far. Again, on the same machine the VWD shows the dialog with sql server option regularly, but VC# shows only 3 options in "Change data source" dialog (1. Microsoft Access Database File (OLE DB) 2. Microsoft SQL Server Compact 3.5, 3. Microsoft SQL Server Database File) Any idea? Thanks in advice, Phil

• How do I determine a best-fit distribution in java?

  - by Eadwacer

  I have a bunch of sets of data (between 50 to 500 points, each of which can take a positive integral value) and need to determine which distribution best describes them. I have done this manually for several of them, but need to automate this going forward. Some of the sets are completely modal (every datum has the value of 15), some are strongly modal or bimodal, some are bell-curves (often skewed and with differing degrees of kertosis/pointiness), some are roughly flat, and there are any number of other possible distributions (possion, power-law, etc.). I need a way to determine which distribution best describes the data and (ideally) also provides me with a fitness metric so that I know how confident I am in the analysis. Existing open-source libraries would be ideal, followed by well documented algorithms that I can implement myself.

• issues with horizontal scrolling using jQuery.ScrollTo / jQuery.SerialScroll

  - by kapil.israni

  Hi, I am trying to develop auto horizontal scrolling for our website using - jQuery.ScrollTo / jQuery.SerialScroll. I am not sure if this is the best jquery library to do that, but if there's something better, please let me know. Here's the behavior that I want, check out foursquare's "Recent Activity" list. The data that will refresh will come from a ajax request that I make every few seconds using window.setInterval. I am not really a CSS/java script guy so I havent been able to figure out jQuery.SerialScroll. Here's the website - look at the "Live job Feeds" list. Currently the list does refresh the data coming from the ajax call, but I dont see the effect, the animation, in fact I dont even think serialScroll is being used. Right now I am doing a - $('#feed-ticker').prepend(content) to pre-append the newly arrived data. You can do a view source to look at the current code. Any help would be really appreciated. Thanks.

• Looking for fully managed WeifenLuo(DockPanel Suite) replacement or hints on implementing one

  - by luiscubal

  I need a WeifenLuo replacement that'll run on both .NET and Mono, on Windows, Linux and Mac, preferrably licensed under the MIT license. I'd appreciate if the API was similar to WeifenLuo's, but I understand that such may not be available. Also, since I couldn't find anything on Google, I believe this might not exist. In this case, I'd like some hints regarding how to implement this. I have some(not much) Windows.Forms experience, and I must not use any P/Invoke. I already know out how to detect window motion and how to create a borderless translucent window on a given position and with a given size. So here are some problems I am facing: WeifenLuo supports multiple left/right/top/bottom panes, allowing them to be resized and contain more than one panel. It also supports splittable tabs. Is there anything else I should be aware of before starting? Are there similar open-source projects available?

• NoSQL with MongoDB, NoRM and ASP.NET MVC - Part 2

  - by shiju

   In my last post, I have given an introduction to MongoDB and NoRM using an ASP.NET MVC demo app. I have updated the demo ASP.NET MVC app and a created a new drop at codeplex. You can download the demo at http://mongomvc.codeplex.com/In my last post, we have discussed to doing basic CRUD operations against a simple domain entity. In this post, let’s discuss on domain entity with deep object graph.The below is our domain entities  public class Category {       [MongoIdentifier]     public ObjectId Id { get; set; }       [Required(ErrorMessage = "Name Required")]     [StringLength(25, ErrorMessage = "Must be less than 25 characters")]     public string Name { get; set;}     public string Description { get; set; }     public List<Expense> Expenses { get; set; }       public Category()     {         Expenses = new List<Expense>();     } }    public class Expense {     [MongoIdentifier]     public ObjectId Id { get; set; }     public Category Category { get; set; }     public string  Transaction { get; set; }     public DateTime Date { get; set; }     public double Amount { get; set; }   }   We have two domain entities - Category and Expense. A single category contains a list of expense transactions and every expense transaction should have a Category.The MongoSession class  internal class MongoSession : IDisposable {     private readonly MongoQueryProvider provider;       public MongoSession()     {         this.provider = new MongoQueryProvider("Expense");     }       public IQueryable<Category> Categories     {         get { return new MongoQuery<Category>(this.provider); }     }     public IQueryable<Expense> Expenses     {         get { return new MongoQuery<Expense>(this.provider); }     }     public MongoQueryProvider Provider     {         get { return this.provider; }     }       public void Add<T>(T item) where T : class, new()     {         this.provider.DB.GetCollection<T>().Insert(item);     }       public void Dispose()     {         this.provider.Server.Dispose();     }     public void Delete<T>(T item) where T : class, new()     {         this.provider.DB.GetCollection<T>().Delete(item);     }       public void Drop<T>()     {         this.provider.DB.DropCollection(typeof(T).Name);     }       public void Save<T>(T item) where T : class,new()     {         this.provider.DB.GetCollection<T>().Save(item);                }     }     ASP.NET MVC view model  for Expense transaction  public class ExpenseViewModel {     public ObjectId Id { get; set; }       public ObjectId CategoryId { get; set; }       [Required(ErrorMessage = "Transaction Required")]            public string Transaction { get; set; }       [Required(ErrorMessage = "Date Required")]            public DateTime Date { get; set; }       [Required(ErrorMessage = "Amount Required")]        public double Amount { get; set; }       public IEnumerable<SelectListItem> Category { get; set; } }  Let's create action method for Insert and Update a expense transaction   [HttpPost] public ActionResult Save(ExpenseViewModel expenseViewModel) {     try     {         if (!ModelState.IsValid)         {             using (var session = new MongoSession())             {                 var categories = session.Categories.AsEnumerable<Category>();                 expenseViewModel.Category = categories.ToSelectListItems(expenseViewModel.CategoryId);                }             return View("Save", expenseViewModel);         }           var expense=new Expense();         ModelCopier.CopyModel(expenseViewModel, expense);           using (var session = new MongoSession())         {             ObjectId Id = expenseViewModel.CategoryId;             var category = session.Categories                 .Where(c => c.Id ==Id  )                 .FirstOrDefault();             expense.Category = category;             session.Save(expense);         }         return RedirectToAction("Index");     }     catch     {         return View();     } } Query with Expenses  using (var session = new MongoSession()) {     var expenses = session.Expenses.         Where(exp => exp.Date >= StartDate && exp.Date <= EndDate)         .AsEnumerable<Expense>(); }  We are doing a LINQ query expression with a Date filter. We can easily work with MongoDB using NoRM driver and can managing object graph of domain entities are pretty cool. Download the Source - You can download the source code form http://mongomvc.codeplex.com

• Rails, gmail: howto get plain/text from body

  - by atmorell

  Hello, I am loading am email with IMAP and parsing it with mail. This works very well, however the mail.body.decoded field contains a lot of formatting. How do I dig out the plain/txt body of the email - ignore attachements, formatting etc. It works fine if I try with an email without html. source = imap.uid_fetch(uid, ['RFC822']).first.attr['RFC822'] mail = Mail.new(source) This body content looks like this: Mail::Body:0x7f36ed468270 @epilogue="", @boundary="_004_4C49171DCB8C4540844E69DD39FDD98Ffirm_", @encoding="7bit", @raw_source="--_004_4C49171DCB8C4540844E69DD39FDD98Ffirm_\r\nContent-Type: multipart/alternative;\r\n\tboundary=\"_000_4C49171DCB8C4540844E69DD39FDD98Ffirm_\"\r\n\r\n--_000_4C49171DCB8C4540844E69DD39FDD98Ffirm_\r\nContent-Type: text/plain; charset=\"iso-8859-1\"\r\nContent-Transfer-Encoding: quoted-printable\r\n\r\ndasdsasda\r\n\r\n\r\n\r\nMed venlig hilsen / Med V=E4nlig H=E4lsning / Best Regards\r\r\nAsbj=F8rn Toke Morell. .\r\n+45 7020 0160\r\n+45 2152 0015\r\n[cid:[email protected]]\r\nhttp://www..dk\r\n\r\n\r\n--_000_4C49171DCB8C4540844E69DD39FDD98Ffirm_\r\nContent-Type: text/html; charset=\"iso-8859-1\"\r\nContent-Transfer-Encoding: quoted-printable\r\n\r\n<html>headheadbody style3D"word-wrap: break-word; -webkit-nbsp-mode:=\r\n space; -webkit-line-break: after-white-space; ">dasdsasda<br><div apple-co=\r\nntent-edited=3D"true">\r\n<span class=3D"Apple-style-span" style=3D"border-collapse: separate; color:=\r\n rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: norma=\r\nl; font-variant: normal; font-weight: normal; letter-spacing: normal; line-=\r\nheight: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transf=\r\norm: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-borde=\r\nr-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-te=\r\nxt-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-tex=\r\nt-stroke-width: 0px; "><span class=3D"Apple-style-span" style=3D"font-famil=\r\ny: Calibri, sans-serif; font-size: 15px; "><span class=3D"Apple-style-span"=\r\n style=3D"border-collapse: separate; color: rgb(0, 0, 0); font-family: Helv=\r\netica; font-size: medium; font-style: normal; font-variant: normal; font-we=\r\night: normal; letter-spacing: normal; line-height: normal; orphans: 2; text=\r\n-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-sp=\r\nacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical=\r\n-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-=\r\nadjust: auto; -webkit-text-stroke-width: 0px; "><span class=3D"Apple-style-=\r\nspan" style=3D"font-family: Calibri, sans-serif; font-size: 15px; "><div st=\r\nyle=3D"margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-=\r\nleft: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; "><font class=\r\n=3D"Apple-style-span" color=3D"#000080" face=3D"'Times New Roman', serif" s=\r\nize=3D"3"><span class=3D"Apple-style-span" style=3D"font-size: 13px; "><br =\r\nclass=3D"Apple-interchange-newline"><br></span></font></div><div style=3D"m=\r\nargin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0c=\r\nm; font-size: 11pt; font-family: Calibri, sans-serif; "><font class=3D"Appl=\r\ne-style-span" color=3D"#000080" face=3D"'Times New Roman', serif" size=3D"3=\r\n"><span class=3D"Apple-style-span" style=3D"font-size: 13px; "><br></span><=\r\n/font></div><div style=3D"margin-top: 0cm; margin-right: 0cm; margin-bottom=\r\n: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-s=\r\nerif; "><span style=3D"font-size: 10pt; font-family: 'Times New Roman', ser=\r\nif; color: navy; ">Med venlig hilsen / Med V=E4nlig H=E4lsning / Best Regar=\r\nds&nbsp;<br>firm<br>Asbj=F8rn Toke Morell...

• Ruby Irb reacts strangely to control keys

  - by eegg

  Hi. I'm (extremely) new to Ruby, having started today. I just moved from my system's Ruby 1.8 installation to Ruby 1.9, compiled from source. In doing so, irb has taken a turn for the worse. It reacts in a most unfriendly way to the non-alphanumeric control keys: UP key prints: ^[[A DOWN key prints: ^[[B DELETE key prints: ^[[3~ ...and so on. The main result of this for me is that I have no access to previously issued commands. Nor does tab-completion work; though none of this seems to be an issue with Wirble - the same happens when I remove my ~/.irbrc. I'm using: Ubuntu 9.10 GNOME Terminal 2.28.1 ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux] Irb version 0.9.5 (05/04/13) Any ideas? :(

• Assert a good practice or not ?

  - by rkenshin

  Is it a good practice to use Assert for function parameters to enforce their validity. I was going through the source code of Spring Framework and I noticed that they use Assert.notNull a lot. Here's an example public static ParsedSql parseSqlStatement(String sql) { Assert.notNull(sql, "SQL must not be null");} Here's Another one public NamedParameterJdbcTemplate(DataSource dataSource) { Assert.notNull(dataSource, "The [dataSource] argument cannot be null."); this .classicJdbcTemplate = new JdbcTemplate(dataSource); } public NamedParameterJdbcTemplate(JdbcOperations classicJdbcTemplate) { Assert.notNull(classicJdbcTemplate, "JdbcTemplate must not be null"); this .classicJdbcTemplate = classicJdbcTemplate; } Thank you

• Merge\Combine two datatables

  - by madlan

  I'm trying to merge\combine two datatables. I've looked at various examples and answers but they seem to create duplicate rows or require indexes (merge on datatable etc) I can't do this via SQL as one source is from a linked Oracle server accessed via MSSQL and the other from a different MSSQL Server that does not have linked access. The data is currently very simple: Name, Email, Phone DataTable1: "John Clark", "", "01522 55231" "Alex King", "[email protected]", "01522 55266" "Marcus Jones", "[email protected]", "01522 55461" DataTable2: "John Clark", "[email protected]", "01522 55231" "Alex King", "[email protected]", "" "Marcus Jones", "[email protected]", "01522 55461" "Warren bean", "[email protected]", "01522 522311" Giving a datatable with the following: "John Clark", "[email protected]", "01522 55231" "Alex King", "[email protected]", "01522 55266" "Marcus Jones", "[email protected]", "01522 55461" "Warren bean", "[email protected]", "01522 522311" Name is the field to match records on, with the first datatable taking priority.

• Create multi-part message in MIME format Freemarker template

  - by Mat Banik

  How do you create email message that contains text and HTML version for the same content? Of course I would like to know how to setup the freemarker template or the header of the message that will be send. When I look on the source of message multi-part message in MIME format that I receive in inbox every once in while this is what is in there: This is a multi-part message in MIME format. ------=_NextPart_000_B10D_01CBAAA8.F29DB300 Content-Type: text/plain Content-Transfer-Encoding: 7bit ...Text here... ------=_NextPart_000_B10D_01CBAAA8.F29DB300 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <html><body> html code here ... </body></html>

• System.Reflection - Global methods aren't available for reflection

  - by mrjoltcola

  I have an issue with a semantic gap between the CLR and System.Reflection. System.Reflection does not (AFAIK) support reflecting on global methods in an assembly. At the assembly level, I must start with the root types. My compiler can produce assemblies with global methods, and my standard bootstrap lib is a dll that includes some global methods. My compiler uses System.Reflection to import assembly metadata at compile time. It seems if I depend on System.Reflection, global methods are not a possibility. The cleanest solution is to convert all of my standard methods to class static methods, but the point is, my language allows global methods, and the CLR supports it, but System.Reflection leaves a gap. ildasm shows the global methods just fine, but I assume it does not use System.Reflection itself and goes right to the metadata and bytecode. Besides System.Reflection, is anyone aware of any other 3rd party reflection or disassembly libs that I could make use of (assuming I will eventually release my compiler as free, BSD licensed open source).

• How to refactor large projects in visual studio

  - by Aaron

  I always run into a problem where my projects in Visual Studio (2008) become huge monstrosities and everything is generally thrown into a Web Application project. I know from checking out some open source stuff that they tend to have multiple projects within a solution, each with their own responsibilities. Does anyone have any advice for how to refactor this out? What should be in a separate project vs. part of the web project? Can you point me to any reference materials on the subject, or is it just something you become accustomed to with time?

• How to get Webkit Browser DBus Bridge working?

  - by SS

  I've been struggling to get the Browser Dbus Binding working for Webkit/GTK (http://gitorious.org/webkitgtk/stable) port. I have been able to successfully compile the Webkit/GTK port as well as the DBus binding library on my Ubuntu Lucid Beta. I also installed the DBus binding library at the standard location /usr/local/lib. But now when I launch the Webkit/GTK browser and try to run one of the sample html files that are provided with DBus binding source, I get "Browser D-Bus Bridge not available, cannot run tests." Basically, JavaScript cannot find window.dbus object. Can anyone tell me what needs to be done here?

• How to automatically add SVN commit messages and revision numbering to java file?

  - by John

  I'm working on an Apache Wicket project in Eclipse with Maven2 -- my SCM is Subversion. I've got Subclipse set up which I use to commit changes to the repository. I've seen several projects with nice headers containing the current revision number and at the bottom of the java source file there's a list of all the changes that have been committed to the file including the comments that were passed. Is there any way of achieving this sort of behaviour automatically? At work I'm using MKS which does this automatically but I am yet to figure out how to achieve this with SVN and Eclipse.

• Spring MVC absolute URL problem

  - by Umar

  Background I am developing an application (with Spring MVC) with its base path as: http://localhost:8080/myapplication/ I have a stylesheet /css/style.css that I am trying to refer with absolute path in a JSP as: <link rel="stylesheet" href="/css/style.css" type="text/css" media="screen, projection"> Problem The stylesheet never loads in the browser. When I follow the stylesheet link through browser's view source feature, the link appears to be: http://localhost:8080/css/style.css Which should have had been: http://localhost:8080/myapplication/css/style.css I used to fix this issue with html:rewrite tag while working with Struts. Is there any equivalent tag/technique in Spring MVC? Thanks for your time.

• Port scientific software to GPU and publish it

  - by Werner

  Hi, let's say that I am a physicist and that I am the master of the universe when it comes to port salready existing oftware to GPU's with 100x or more speedups. Let's say that I find that some other scientist, which does not know how to program GPU, publishes the Open Source code in his/her website of a physical simulation program, in the field I am expert on. Let's say that I realize "I can port that code to GPU", and I suggest him, but he shows no interest. My interest here is, 1) to port it to GPU, 2) to publish this result in a scientific journal related with physics and/or computer science My question for you is 1- would you proceed here to port the code to GPU (or other new arch) and publish it? 2- how would you do it and which journal do you suggest? Thanks

• How do I implement IDataServiceMetadataProvider and tell my Data Service to use that custom provider

  - by Pwninstein

  There's no obvious entry point for implementing a custom provider for an ADO.NET Data Service using IDataServiceMetadataProvider, and then telling a Data Service to use that provider. Has anyone had any luck in this area? I've tried implementing this interface on my Data Source class, but none of my breakpoints are hit. There is also no (obvious) way to set the provider from the Data Service's DataServiceConfiguration parameter passed in to the InitializeService function. Any help would be appreciated. Thanks!

• HTML table to “graphical text” for code comments

  - by Atif Aziz

  Is there a tool (ideally command-line-based) that can help in converting the source to HTML tables into “graphical text” (think perhaps ASCII art for HTML tables) for use in code comments (like /*…*/), as show below? /* +--------------------------------------------------------------------+ | Network | +--------------------------------------------------------------------+ | 11.05.2010 | ABC | DEF | +------------+-------------+-------------+-------------+-------------+ | | INPUT | OUTPUT | INPUT | OUTPUT | +------------+-------------+-------------+-------------+-------------+ | Value | 366,899,791 | 0 | 213,001 | 2,132,827 | +------------+-------------+-------------+-------------+-------------+ */ Background: A piece of code that reads values from HTML tables can be annotated with comments depicting text-based graphical representations of complex HTML table layouts. Someone maintaining the code later can then find it easier to understand, for example, how a piece of code is slicing and dicing an HTML table or plucking values at certain cell positions.

• What are modern and old compilers written in?

  - by ulum

  As a compiler, other than an interpreter, only needs to translate the input and not run it the performance of itself should be not that problematic as with an interpreter. Therefore, you wouldn't write an interpreter in, let's say Ruby or PHP because it would be far too slow. However, what about compilers? If you would write a compiler in a scripting language maybe even featuring rapid development you could possibly cut the source code and initial development time by halv, at least I think so. To be sure: With scripting language I mean interpreted languages having typical features that make programming faster, easier and more enjoyable for the programmer, usually at least. Examples: PHP, Ruby, Python, maybe JavaScript though that may be an odd choice for a compiler What are compilers normally written in? As I suppose you will respond with something low-level like C, C++ or even Assembler, why? Are there compilers written in scripting languages? What are the (dis)advantages of using low or high level programming languages for compiler writing?
