  • Getting ActiveRecord (Rails) to_xml to use xsi:nil and xsi:type instead of nil and type

    - by nbeyer
    The default behavior of XML serialization (to_xml) for ActiveRecord objects will emit 'type' and 'nil' attributes that are similar to XML Schema Instance attributes, but aren't set in a XML Namespace. For example, a model might produce an output like this: <user> <username nil="true" /> <first-name type="string">Name</first-name> </user> Is there anyway to get to_xml to utilize the XML Schema Instance namespace and prefix the attributes and the values? Using the above example, I'd like to produce the following: <user xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xs="http://www.w3.org/1999/XMLSchema"> <username xsi:nil="true" /> <first-name xsi:type="xs:string">Name</first-name> </user>

  • SQL WHERE clause not returning rows when field has NULL value

    - by JohnB
    Ok, so I'm aware of this issue: When SET ANSI_NULLS is ON, all comparisons against a null value evaluate to UNKNOWN SQL And NULL Values in where clause SQL Server return Rows that are not equal < to a value and NULL However, I am trying to query a DataTable. I could add to my query: OR col_1 IS NULL OR col_2 IS NULL for every column, but my table has 47 columns, and I'm building dynamic SQL (string concatenation), and it just seems like a pain to do that. Is there another solution? I was to bring back all the rows that have NULL values in the WHERE comparison. UPDATE Example of query that gave me problems: string query = col_1 not in ('Dorothy', 'Blanche') and col_2 not in ('Zborna', 'Devereaux') grid.DataContext = dataTable.Select(query).CopyToDataTable(); (didn't retrieve rows if/when col_1 = null and/or col_2 = null)

  • ASP.NET MVC Route Default values

    - by Sadegh
    hi, i defined two routes in global.asax like below context.MapRoute("HomeRedirect", "", new { controller = "Home", action = "redirect" }); context.MapRoute("UrlResolver", "{culture}/some", new { culture = "en-gb", controller = "someController", action = "someAction" }, new { culture = new CultureRouteConstraint() }); according to above definition, when user request mysite.com/ redirect action of HomeController should be called and in that: public class HomeController : Controller { public ActionResult Redirect() { return RedirectToRoute("UrlResolver"); } } i want to redirect user to second defined route on above, so also i specified default values for that and some Constraint for each of those. but when RedirectToRoute("UrlResolver") turns, no default values passed to routeConstraints on second route and No route in the route table matches the supplied values shows. update my CultureRouteConstraint: public class CultureRouteConstraint : IRouteConstraint { bool IRouteConstraint.Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { try { var parameter = values[parameterName] as string; return (someCondition(parameter)); } catch { return false; } } } now values parameter haven't culture key/value, but route parameter have that.

  • MVVM && IOC && Sub-ViewModels

    - by Lee Treveil
    I have a ViewModel, it takes two parameters in the constructor that are of the same type: public class CustomerComparerViewModel { public CustomerComparerViewModel(CustomerViewModel customerViewModel1, CustomerViewModel customerViewModel2) { } } public class CustomerViewModel { public string FirstName { get; set; } public string LastName { get; set; } } If I wasn't using IOC I could just new up the viewmodel and pass the sub-viewmodels in. I could package the two viewmodels into one class and pass that into the constructor but if I had another viewmodel that only needed one CustomerViewModel I would need to pass in something that the viewmodel does not need. How do I go about dealing with this using IOC? I'm using Ninject btw. Thanks

  • Big 0 theta notation

    - by niggersak
    Can some pls help with the solution Use big-O notation to classify the traditional grade school algorithms for addition and multiplication. That is, if asked to add two numbers each having N digits, how many individual additions must be performed? If asked to multiply two N-digit numbers, how many individual multiplications are required? Suppose f is a function that returns the result of reversing the string of symbols given as its input, and g is a function that returns the concatenation of the two strings given as its input. If x is the string hrwa, what is returned by g(f(x),x)? Explain your answer - don't just provide the result!

  • How do you get Matlab to write the BOM (byte order markers) for UTF-16 text files?

    - by Richard Povinelli
    I am creating UTF16 text files with Matlab, which I am later reading in using Java. In Matlab, I open a file called fileName and write to it as follows: fid = fopen(fileName, 'w','n','UTF16-LE'); fprintf(fid,"Some stuff."); In Java, I can read the text file using the following code: FileInputStream fileInputStream = new FileInputStream(fileName); Scanner scanner = new Scanner(fileInputStream, "UTF-16LE"); String s = scanner.nextLine(); Here is the hex output: Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 00000000 73 00 6F 00 6D 00 65 00 20 00 73 00 74 00 75 00 66 00 66 00 s.o.m.e. .s.t.u.f.f. The above approach works fine. But, I want to be able to write out the file using UTF16 with a BOM to give me more flexibility so that I don't have to worry about big or little endian. In Matlab, I've coded: fid = fopen(fileName, 'w','n','UTF16'); fprintf(fid,"Some stuff."); In Java, I change the code to: FileInputStream fileInputStream = new FileInputStream(fileName); Scanner scanner = new Scanner(fileInputStream, "UTF-16"); String s = scanner.nextLine(); In this case, the string s is garbled, because Matlab is not writing the BOM. I can get the Java code to work just fine if I add the BOM manually. With the added BOM, the following file works fine. Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 00000000 FF FE 73 00 6F 00 6D 00 65 00 20 00 73 00 74 00 75 00 66 00 66 00 ÿþs.o.m.e. .s.t.u.f.f. How can I get Matlab to write out the BOM? I know I could write the BOM out separately, but I'd rather have Matlab do it automatically. Addendum I selected the answer below from Amro because it exactly solves the question I posed. One key discovery for me was the difference between the Unicode Standard and a UTF (Unicode transformation format) (see http://unicode.org/faq/utf_bom.html). The Unicode Standard provides unique identifiers (code points) for characters. UTFs provide mappings of every code point "to a unique byte sequence." Since all but a handful of the characters I am using are in the first 128 code points, I'm going to switch to using UTF-8 as Romeo suggests. UTF-8 is supported by Matlab (The warning shown below won't need to be suppressed.) and Java, and for my application will generate smaller text files. I suppress the Matlab warning Warning: The encoding 'UTF-16LE' is not supported. with warning off MATLAB:iofun:UnsupportedEncoding;

  • Asp.NET MVC ActionFilter cannot get Form Submit data

    - by Goden
    I want to use custom action filter to manipulate parameters to one action. User inputs: 2 names in a form ; Action: actually needs to take 2 ids; Action Filter (onExecuting, will verify the input names and if valid, convert them into 2 ids and replace in the routedata) because i don't want to put validation logic in Action Controller. here's part of the code: Routing Info routes.MapRoute( "Default", // Route name "{controller}/{action}", // URL with parameters new { controller = "Home", action = "Index"} // Parameter defaults ); routes.MapRoute( "RelationshipResults", // Route Name "Relationship/{initPersonID}/{targetPersonID}", // URL with parameters new { controller = "Relationship", action = "Results" }); Form to submit (Create 2 input box and submit via jquery) <% using (Html.BeginForm("Results", "Relationship", FormMethod.Post, new { id = "formSearch" })) {% ... <td align="left"><%: MvcWeibookWeb.Properties.Resource.Home_InitPersonName%></td> <td align="right"> <%= Html.TextBox("initPersonName")%></td> <td rowspan="3" valign="top"> <div id="sinaIntro"> <%: MvcWeibookWeb.Properties.Resource.Home_SinaIntro %> <br /> <%: MvcWeibookWeb.Properties.Resource.Genearl_PromotionSina %> </div> </td> </tr> <tr> <td align="left" width="90px"><%: MvcWeibookWeb.Properties.Resource.Home_TargetPersonName%></td> <td align="right"><%= Html.TextBox("targetPersonName")%></td> </tr> <tr> <td colspan="2" align="right"> <a href="#" class="btn-HomeSearch" onclick="$('#formSearch').submit();"><%: MvcWeibookWeb.Properties.Resource.Home_Search%></a> </td> Action Filter public override void OnActionExecuting(ActionExecutingContext filterContext) { Sina.Searcher searcher = new Sina.Searcher(Sina.Processor.UserNetwork); String initPersonName, targetPersonName; // form submit names, we need to process them and convert them to IDs before it enters the real controller. initPersonName = filterContext.RouteData.Values["initPersonName"] as String; targetPersonName = filterContext.RouteData.Values["targetPersonName"] as String; // do sth to convert it to ids and replace Action/Controller [ValidationActionFilter] [HandleError] public ActionResult Results( Int64 initPersonName, Int64 targetPersonName) { ...

  • .Net Custom Configuration Section and Saving Changes within PropertyGrid

    - by Paul
    If I load the My.Settings object (app.config) into a PropertyGrid, I am able to edit the property inside the propertygrid and the change is automatically saved. PropertyGrid1.SelectedObject = My.Settings I want to do the same with a Custom Configuration Section. Following this code example (from here http://www.codeproject.com/KB/vb/SerializePropertyGrid.aspx), he is doing explicit serialization to disk when a "Save" button is pushed. Public Class Form1 'Load AppSettings Dim _appSettings As New AppSettings() Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click _appSettings = AppSettings.Load() ' Actually change the form size Me.Size = _appSettings.WindowSize PropertyGrid1.SelectedObject = _appSettings End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click _appSettings.Save() End Sub End Class In my code, my custom section Inherits from ConfigurationSection (see below) Question: Is there something built into ConfigurationSection class that does the autosave? If not, what is the best way to handle this, should it be in the PropertyGrid.PropertyValueChagned? (how does the My.Settings handle this internally?) Here is the example Custom Class that I am trying to get to auto-save and how I load into property grid. Dim config As System.Configuration.Configuration = _ ConfigurationManager.OpenExeConfiguration( _ ConfigurationUserLevel.None) PropertyGrid2.SelectedObject = config.GetSection("CustomSection") Public NotInheritable Class CustomSection Inherits ConfigurationSection ' The collection (property bag) that contains ' the section properties.

  • Flex actionscript extending DateChooser, events in calendar

    - by Nemi
    ExtendedDateChooser class is great solution for simple event calendar used in my flex project. You can find it if google for "Adding-Calendar-Event-Entries-to-the-Flex-DateChooser-Component" with a link of updated solution in comments of the post. I posted files below. Problem in that calendar is text events are missing when month is changed. Is there updateCompleted event in Actionscript just like in dateChooser flex component? Like in: <mx:DateChooser id="dc" updateCompleted="goThroughDateChooserCalendarLayoutAndSetEventsInCalendarAgain()"</mx> When scroll event is added, which is available in Actionscript, it gets dispatched but after updateDisplayList() is fired, so didn't manage to answer, why are calendar events erased?

  • Debugging ASP.NET Strings Downloaded to Browser (Montréal instead of Montréal)

    - by jdk
    I'm downloading a vCard to the browser using Response.Write to output .NET strings with special accented characters. Mime type is text/x-vcard and French characters are appearing wrong in Outlook, for example Montréal;Québec .NET string shows as Montréal Québec in browser. I'm using this vCard generator code from CodeProject.com I've played with the System.Encoding sample code at the bottom of this linked MSDN page to convert the unicode string into bytes and then write the ascii bytes but then I get Montr?al Qu?bec (progress but not a win). Also I've tried setting content type to both us-ascii and utf-8 of the response. If I open the downloaded vCard in Windows Notepad and save it as ANSI text (instead of default unicode format) and open in Outlook it's okay. So my assumption is I need to cause download of ANSI charset but am unsure if I'm doing it wrong or have a misunderstanding of where to start. Update: Looking at the raw HTTP, it appears my French characters are being downloaded in the unexpected format so it looks like I need to do some work on the server side... (full size)

  • Retrieving well formed HTML using Jericho HTML parser in Java

    - by Raj
    Hello, I've looked at jTidy for converting a snipped of malformed/real-world HTML into well-formed HTML/XHTML. However, there's a bug in the latest version due to which I'm not able to use it. I'm looking at Jericho since it has a lot of positive reviews around the net. However, its not immediately obvious to me how one would go about implementing a method like: public String getValidHTML(String messedUpHTML) For instance, if it was passed <div>bar, it would return <div>bar</div> Any pointers would be helpful. Thanks in advance!

  • Cross-compiling with OpenSSL for Windows

    I'm trying to compile the oauth-utils http://mir.dnsalias.com/oss/oauth/start for Windows from Ubuntu. I have compiled it on Windows before (a few months back), but wanted to try cross-compiling. I got openssl build using mingw32 ok, and put libssl.a and libcrypto.a in the right place.

    - by antongladchenko
    I have an image control with a source image located in my c drive. I get a message that the image is being used by another process whenever I try to delete the original image to change it with another one dynamically. How do I release the image from the image control to be able to delete it. I tried this variants: string path = ((BitmapImage)img.Source).UriSource.LocalPath; img.SetValue(System.Windows.Controls.Image.SourceProperty, null); File.Delete(path); And: string path = ((BitmapImage)img.Source).UriSource.LocalPath; img.Source = null; File.Delete(path) But it's not work...

  • JPQL get most recent rows

    - by Vinnie
    Let's say I have the following tables my_profile_data ------------- integer: profile_id date: date_changed string: value my_profile ------------- integer: profile_id string: name I want to get the most recent profile information. In plain SQL this would look something like: select mpd.profile_id, mpd.value, max(mpd.date_changed) from my_profile_data mpd, my_profile mp where mpd.profile_id = mp.profile_id and mp.name='The Profile I Want' group by mpd.profile_id I've tried different variants of the following JPQL query, but cant get it to work. SELECT mpd FROM MyProfileData mpd LEFT JOIN (SELECT mpd.profileId profileId, MAX(mpd.dateChanged) FROM MyProfileData mpd LEFT JOIN mp.profile WHERE mp.name = :name GROUP BY mpd.profileId) recent ON (rp.profileid = recent.profileId) Is this query doable in JPA? I'm using EclipseLink as my JPA provider. The innermost exception I get when I try to run this is Caused by: NoViableAltException(81!=[506:7: (n= joinAssociationPathExpression ( AS )? i= IDENT | t= FETCH n= joinAssociationPathExpression )]) at org.eclipse.persistence.internal.jpa.parsing.jpql.antlr.JPQLParser.join(JPQLParser.java:3669) ... 73 more

  • SQL Server 2008: FileStream Insertion Failure w/ .NET 3.5SP1

    - by James Alexander
    I've configured a db w/ a FileStream group and have a table w/ File type on it. When attempting to insert a streamed file and after I create the table row, my query to read the filepath out and the buffer returns a null file path. I can't seem to figure out why though. Here is the table creation script: /****** Object: Table [dbo].[JobInstanceFile] Script Date: 03/22/2010 18:05:36 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[JobInstanceFile]( [JobInstanceFileId] [int] IDENTITY(1,1) NOT NULL, [JobInstanceId] [int] NOT NULL, [File] [varbinary](max) FILESTREAM NULL, [FileId] [uniqueidentifier] ROWGUIDCOL NOT NULL, [Created] [datetime] NOT NULL, CONSTRAINT [PK_JobInstanceFile] PRIMARY KEY CLUSTERED ( [JobInstanceFileId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] FILESTREAM_ON [JobInstanceFilesGroup], UNIQUE NONCLUSTERED ( [FileId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] FILESTREAM_ON [JobInstanceFilesGroup] GO SET ANSI_PADDING OFF GO ALTER TABLE [dbo].[JobInstanceFile] ADD DEFAULT (newid()) FOR [FileId] GO Here's my proc I call to create the row before streaming the file: /****** Object: StoredProcedure [dbo].[JobInstanceFileCreate] Script Date: 03/22/2010 18:06:23 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO create proc [dbo].[JobInstanceFileCreate] @JobInstanceId int, @Created datetime as insert into JobInstanceFile (JobInstanceId, FileId, Created) values (@JobInstanceId, newid(), @Created) select scope_identity() GO And lastly, here's the code I'm using: public int CreateJobInstanceFile(int jobInstanceId, string filePath) { using (var connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConsumerMarketingStoreFiles"].ConnectionString)) using (var fileStream = new FileStream(filePath, FileMode.Open)) { connection.Open(); var tran = connection.BeginTransaction(IsolationLevel.ReadCommitted); try { //create the JobInstanceFile instance var command = new SqlCommand("JobInstanceFileCreate", connection) { Transaction = tran }; command.CommandType = CommandType.StoredProcedure; command.Parameters.AddWithValue("@JobInstanceId", jobInstanceId); command.Parameters.AddWithValue("@Created", DateTime.Now); int jobInstanceFileId = Convert.ToInt32(command.ExecuteScalar()); //read out the filestream transaction context to stream the file for storage command.CommandText = "select [File].PathName(), GET_FILESTREAM_TRANSACTION_CONTEXT() from JobInstanceFile where JobInstanceFileId = @JobInstanceFileId"; command.CommandType = CommandType.Text; command.Parameters.AddWithValue("@JobInstanceFileId", jobInstanceFileId); using (SqlDataReader dr = command.ExecuteReader()) { dr.Read(); //get the file path we're writing out to string writePath = dr.GetString(0); using (var writeStream = new SqlFileStream(writePath, (byte[])dr.GetValue(1), FileAccess.ReadWrite)) { //copy from one stream to another byte[] bytes = new byte[65536]; int numBytes; while ((numBytes = fileStream.Read(bytes, 0, 65536)) 0) writeStream.Write(bytes, 0, numBytes); } } tran.Commit(); return jobInstanceFileId; } catch (Exception e) { tran.Rollback(); throw e; } } } Can someone please let me know what I'm doing wrong.

  • sqlite - any improvements for this attach code (running multiple sql commands transactionally in sql

    - by Greg
    Hi, Is this code solid? I've tried to use "using" etc. Basically a method to pass as sequenced list of SQL commands to be run against a Sqlite database. I assume it is true that in sqlite by default all commands run in a single connection are handled transactionally? Is this true? i.e. I should not have to (and haven't got in the code at the moment) a BeginTransaction, or CommitTransaction. It's using http://sqlite.phxsoftware.com/ as the sqlite ADO.net database provider. private int ExecuteNonQueryTransactionally(List<string> sqlList) { int totalRowsUpdated = 0; using (var conn = new SQLiteConnection(_connectionString)) { // Open connection (one connection so should be transactional - confirm) conn.Open(); // Apply each SQL statement passed in to sqlList foreach (string s in sqlList) { using (var cmd = new SQLiteCommand(conn)) { cmd.CommandText = s; totalRowsUpdated = totalRowsUpdated + cmd.ExecuteNonQuery(); } } } return totalRowsUpdated; }
