• SilverLight 3.0 DataGrid LoadingRow Event

  - by Asim Sajjad

  Following are my Question regarding the LoadingRow event of the Datagrid When will it fires after the Row is bound to the data or after that. As if you debug the Silverlight application then of first execution if you type following code ((System.Windows.Controls.TextBlock)(((System.Windows.Controls.ContentControl)(((DataGridRow)e.Row).Cells[1])).Content)).Text if will return empty string but if your datagrid has scroll (which is in my case , my datagrid has scroll), if you scroll down then the LoadingRow firs again and this time it will return Text on that cell?? why it is not return text on first time and return on second time when i press the scroll bar ??? If I paste above code in the cs file then it will return error 'System.Windows.Controls.DataGridRow' does not contain a definition for 'Cells' and no extension method 'Cells' accepting a first argument of type 'System.Windows.Controls.DataGridRow' could be found (are you missing a using directive or an assembly reference?) Can any one help me in these question thanks in advance,

• How can I use Boost::regex.hpp library in C++?

  - by MIH1406

  I tried to use Boost library but I failed, see my code: #include "listy.h" #include <boost/regex.hpp> using namespace boost; ListyCheck::ListyCheck() { } ListyCheck::~ListyCheck() { } bool ListyCheck::isValidItem(std::string &__item) { regex e("(\\d{4}[- ]){3}\\d{4}"); return regex_match(__item, e); } When I tried to compile it I get those messages: /usr/include/boost/regex/v4/regex_match.hpp:50: undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__normal_iterator, std::allocator , std::allocator, std::allocator , boost::regex_traits ::match()' /usr/include/boost/regex/v4/basic_regex.hpp:425: undefined reference to `boost::basic_regex ::do_assign(char const*, char const*, unsigned int)' /usr/include/boost/regex/v4/perl_matcher.hpp:366: undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__normal_iterator, std::allocator , std::allocator, std::allocator , boost::regex_traits ::construct_init(boost::basic_regex const&, boost::regex_constants::_match_flags)' etc...

• IOException reading from HttpWebResponse response stream over SSL

  - by Lawrence Johnston

  I get the following exception when attempting to read the response from my HttpWebRequest: System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream. at System.Net.ConnectStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.IO.StreamReader.ReadBuffer() at System.IO.StreamReader.ReadToEnd() ... My code functions without issue when using http. I am talking to a third-party device; I do not have access to the server code. My code is as follows: private string MakeRequest() { // Disable SSL certificate verification per // http://www.thejoyofcode.com/WCF_Could_not_establish_trust_relationship_for_the_SSL_TLS_secure_channel_with_authority.aspx ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate { return true; }); Uri uri = new Uri("https://mydevice/mypath"); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); request.Method = WebRequestMethods.Http.Get; using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { using (Stream responseStream = response.GetResponseStream()) { using (StreamReader sr = new StreamReader(responseStream.)) { return sr.ReadToEnd(); } } } } Does anybody have any thoughts about what might be causing it?

• XML Parsing from Non-XML Document

  - by Neel Basu

  in a xml/non-xml File there may exist some XML Block that I need to parse and replace with some other string.. The Scenario is something like this.. Some Text <cnt:use name="abc" call="xyz"> <cnt:param name="x" value="2" /> </cnt:use> Some Text There is no guarantee that the document is a proper XML document. (there may exist some unclosed Tags. or some other common mistakes that a Stupid people can make while typing HTML). so I can't use SAX or DOM. I can't even pass it to XSLT (am I right ?). So Whats the best way to extract the <cnt:*> part from the non-xml Document. and read it then replace with something else.

• How to use html2canvas JavaScript with Selenium webdriver in C#

  - by PapyRef

  With selenium webdriver, I would test html2canvas JS script to take "screenshots" of webpages or parts of it, directly on the browser. I have a written this C# code to test it, but obj is always null. C# Code for reference IWebDriver Driver = new FirefoxDriver(); Driver.Navigate().GoToUrl("http://www.monsite.com"); string scriptJS = File.ReadAllText("html2canvas.js"); scriptJS += @" html2canvas(document.body, { onrendered: function(canvas) { var img = canvas.toDataURL("image/png"); return img; } });"; IJavaScriptExecutor executorJS = Driver as IJavaScriptExecutor; var obj = executorJS.ExecuteScript(scriptJS);

• Problem finding office DCOM in Component Services in Windows 7

  - by Tomas I

  I have a problem getting my word and excel to work in ASP .NET. I get the error message: {System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005. at xxx.Utility.WordDocument..ctor(String filePath, HttpServerUtility util) at customer_communication.BuCreate_click(Object sender, EventArgs e) in This means I have access problem to the DCOM files. In Vista this isnt a problem, all I have to do there is to run "dcomcnfg" and in there find the Microsoft Excel dcom file. In Windows 7 I cant find it, and I have no idea what to do now... If anyone could help me that would be great!

• Cannot SSH after resetting firewall on VPS

  - by Thomas Buckley

  I'm having trouble trying to SSH to my Debian 5 VPS with blacknight. It was working fine until I did the following: Logged into 'Parallels Infrastructure Manager' - Container - Firewall - Set to 'Normal Firewall settings'. It told me there was an error with the IPTables and offered the option again with a checkbox to 'reset' firewall settings, I selected this. I can see that that the default rules are been applied ( anything from anyone on any port and allowing anything to happen).

• Locking Cache Key without Locking the entire Cache

  - by Gandalf

  I have servlets that caches user information rather then retrieving it from the user store on every request (shared Ehcache). The issue I have is that if a client is multi-threaded and they make more then one simultaneous request, before they have been authenticated, then I get this in my log: Retrieving User [Bob] Retrieving User [Bob] Retrieving User [Bob] Returned [Bob] ...caching Returned [Bob] ...caching Returned [Bob] ...caching What I would want is that the first request would call the user service, while the other two requests get blocked - and when the first request returns, and then caches the object, the other two requests go through: Retrieving User [Bob] blocking... blocking... Returned [Bob] ...caching [Bob] found in cache [Bob] found in cache I've thought about locking on the String "Bob" (because due to interning it's always the same object right?). Would that work? And if so how do I keep track of the keys that actually exist in the cache and build a locking mechanism around them that would then return the valid object once it's retrieved. Thanks.

• WMI Win32_OperatingSystem OSArchitecture field causes exception

  - by Andrew J. Brehm

  I am trying to get information on the version of Windows installed from WMI. Most fields work. I can get the operating system "Name" as well as the "Version", both are fields of the Win32_OperatingSystem object I have. But another field "OSArchitecture" generates an exception ("Not found"). strScope = "\\" + strServer + "\root\CIMV2" searcher = New ManagementObjectSearcher(strScope, "SELECT * FROM Win32_OperatingSystem") For Each mo In searcher.Get strOSName = mo("Name") strOSVersion = mo("Version") strOSArchitecture = mo("Architecture") strStatus = mo("Status") strLastBoot = mo("LastBootUpTime") Next The documentation says that the field ought to exist and is a String: http://msdn.microsoft.com/en-us/library/aa394239(VS.85).aspx Any ideas?

• SUBSONIC 3.0.0.3 Subsonic.Query.SqlQuery

  New to subsonic and having issues figuring it out. I am simply just trying to do a distinct search and any documentation I find is telling me to use the class/method SubSonic.SqlQuery Though I am finding out that since I am using the newest version, a lot of the documentation I am finding does not apply. For example, I am getting this query working beautifully using Subsonic.Query.SqlQuery though there is NO distinct method hanging off of it as suggested by what I have seen. Please advice! SubSonic.Query.SqlQuery query = brickDB.SelectColumns(new string[] { "DomainName" }).From<Web.Data.DB.WebLog>() .Where(Web.Data.DB.WebLogTable.DomainNameColumn).IsNotNull(); -> No distinct hanging off of From<>()....

• Flash Player 10.1 crash on shared object access

  - by Simon

  Hi all, since updating my Flash Player plugin from 10 to 10.1, I'm seeing a weird crash when accessing shared objects. Flex Builder's debugger pops up and prints a stack trace like this: undefined at flash.net::SharedObject$/getLocal() at my.code::MyClass$/load()[/my/path/to/my/MyClass.as:27] (...) This happens when calling SharedObject.getLocal("someString") for the second time for the same string, though it doesn't always crash. When using another browser on the same machine (not configured as the preferred debugging browser in Flex Builder), Flash Player remains silent. The code is wrapped in a try/catch(Error) block which does not catch this error. I'm using Flex SDK 3.5 and Flex Builder 3 on Mac OS X 10.6.3. Has anyone else seen this? Thanks, Simon

• Sending and receiving a TMemoryStream using IdTCPClient and IdTCPServer

  - by Martin Melka

  I found Remy Lebeau's chat demo of IdTCP components in XE2 and I wanted to play with it a little bit. (It can be found here) I would like to send a picture using these components and the best approach seems to be using TMemoryStream. If I send strings, the connection works fine, the strings are transmitted successfully, however when I change it to Stream instead, it doesn't work. Here is the code: Server procedure TMainForm.IdTCPServerExecute(AContext: TIdContext); var rcvdMsg: string; ms:TMemoryStream; begin // This commented code is working, it receives and sends strings. // rcvdMsg:=AContext.Connection.IOHandler.ReadLn; // LogMessage('<ServerExec> '+rcvdMsg); // // TResponseSync.SendResponse(AContext, rcvdMsg); try ms:=TMemoryStream.Create; AContext.Connection.IOHandler.ReadStream(ms); ms.SaveToFile('c:\networked.bmp'); except LogMessage('Failed to receive',clred); end; end; Client procedure TfrmMain.Button1Click(Sender: TObject); var ms: TMemoryStream; bmp: TBitmap; pic: TPicture; s: string; begin // Again, this code is working for sending strings. // s:=edMsg.Text; // Client.IOHandler.WriteLn(s); ms:=TMemoryStream.Create; pic:=TPicture.Create; pic.LoadFromFile('c:\Back.png'); bmp:=TBitmap.Create; bmp.Width:=pic.Width; bmp.Height:=pic.Height; bmp.Canvas.Draw(0,0,pic.Graphic); bmp.SaveToStream(ms); ms.Position:=0; Client.IOHandler.Write(ms); ms.Free; end; When I try to send the stream from the client, nothing observable happens (breakpoint in the OnExecute doesn't fire). However, when closing the programs(after sending the MemoryStream), two things happen: If the Client is closed first, only then does the except part get processed (the log displays the 'Failed to receive' error. However, even if I place a breakpoint on the first line of the try-except block, it somehow gets skipped and only the error is displayed). If the Server is closed first, the IDE doesn't change back from debug, Client doesn't change its state to disconnected (as it normally does when server disconnects) and after the Client is closed as well, an Access Violation error from the Server app appears. I guess this means that there is a thread of the Server still running and maintaining the connection. But no matter how much time i give it, it never completes the task of receiving the MemoryStream. Note: The server uses IdSchedulerOfThreadDefault and IdAntiFreeze, if that matters. As I can't find any reliable source of help for the revamped Indy 10 (it all appears to apply for the older Indy 10, or even Indy 9), I hope you can tell me what is wrong. Thanks - ANSWER - SERVER procedure TMainForm.IdTCPServerExecute(AContext: TIdContext); var size: integer; ms:TMemoryStream; begin try ms:=TMemoryStream.Create; size:=AContext.Connection.IOHandler.ReadLongInt; AContext.Connection.IOHandler.ReadStream(ms, size); ms.SaveToFile('c:\networked.bmp'); except LogMessage('Failed to receive',clred); end; end; CLIENT procedure TfrmMain.Button1Click(Sender: TObject); var ms: TMemoryStream; bmp: TBitmap; pic: TPicture; begin ms:=TMemoryStream.Create; pic:=TPicture.Create; pic.LoadFromFile('c:\Back.png'); bmp:=TBitmap.Create; bmp.Width:=pic.Width; bmp.Height:=pic.Height; bmp.Canvas.Draw(0,0,pic.Graphic); bmp.SaveToStream(ms); ms.Position:=0; Client.IOHandler.Write(ms, 0, True); ms.Free; end;

• Entity Framework 4.0 and DDD patterns

  - by Voice

  Hi everybody I use EntityFramework as ORM and I have simple POCO Domain Model with two base classes that represent Value Object and Entity Object Patterns (Evans). These two patterns is all about equality of two objects, so I overrode Equals and GetHashCode methods. Here are these two classes: public abstract class EntityObject<T>{ protected T _ID = default(T); public T ID { get { return _ID; } protected set { _ID = value; } } public sealed override bool Equals(object obj) { EntityObject<T> compareTo = obj as EntityObject<T>; return (compareTo != null) && ((HasSameNonDefaultIdAs(compareTo) || (IsTransient && compareTo.IsTransient)) && HasSameBusinessSignatureAs(compareTo)); } public virtual void MakeTransient() { _ID = default(T); } public bool IsTransient { get { return _ID == null || _ID.Equals(default(T)); } } public override int GetHashCode() { if (default(T).Equals(_ID)) return 0; return _ID.GetHashCode(); } private bool HasSameBusinessSignatureAs(EntityObject<T> compareTo) { return ToString().Equals(compareTo.ToString()); } private bool HasSameNonDefaultIdAs(EntityObject<T> compareTo) { return (_ID != null && !_ID.Equals(default(T))) && (compareTo._ID != null && !compareTo._ID.Equals(default(T))) && _ID.Equals(compareTo._ID); } public override string ToString() { StringBuilder str = new StringBuilder(); str.Append(" Class: ").Append(GetType().FullName); if (!IsTransient) str.Append(" ID: " + _ID); return str.ToString(); } } public abstract class ValueObject<T, U> : IEquatable<T> where T : ValueObject<T, U> { private static List<PropertyInfo> Properties { get; set; } private static Func<ValueObject<T, U>, PropertyInfo, object[], object> _GetPropValue; static ValueObject() { Properties = new List<PropertyInfo>(); var propParam = Expression.Parameter(typeof(PropertyInfo), "propParam"); var target = Expression.Parameter(typeof(ValueObject<T, U>), "target"); var indexPar = Expression.Parameter(typeof(object[]), "indexPar"); var call = Expression.Call(propParam, typeof(PropertyInfo).GetMethod("GetValue", new[] { typeof(object), typeof(object[]) }), new[] { target, indexPar }); var lambda = Expression.Lambda<Func<ValueObject<T, U>, PropertyInfo, object[], object>>(call, target, propParam, indexPar); _GetPropValue = lambda.Compile(); } public U ID { get; protected set; } public override Boolean Equals(Object obj) { if (ReferenceEquals(null, obj)) return false; if (obj.GetType() != GetType()) return false; return Equals(obj as T); } public Boolean Equals(T other) { if (ReferenceEquals(null, other)) return false; if (ReferenceEquals(this, other)) return true; foreach (var property in Properties) { var oneValue = _GetPropValue(this, property, null); var otherValue = _GetPropValue(other, property, null); if (null == oneValue && null == otherValue) return false; if (false == oneValue.Equals(otherValue)) return false; } return true; } public override Int32 GetHashCode() { var hashCode = 36; foreach (var property in Properties) { var propertyValue = _GetPropValue(this, property, null); if (null == propertyValue) continue; hashCode = hashCode ^ propertyValue.GetHashCode(); } return hashCode; } public override String ToString() { var stringBuilder = new StringBuilder(); foreach (var property in Properties) { var propertyValue = _GetPropValue(this, property, null); if (null == propertyValue) continue; stringBuilder.Append(propertyValue.ToString()); } return stringBuilder.ToString(); } protected static void RegisterProperty(Expression<Func<T, Object>> expression) { MemberExpression memberExpression; if (ExpressionType.Convert == expression.Body.NodeType) { var body = (UnaryExpression)expression.Body; memberExpression = body.Operand as MemberExpression; } else memberExpression = expression.Body as MemberExpression; if (null == memberExpression) throw new InvalidOperationException("InvalidMemberExpression"); Properties.Add(memberExpression.Member as PropertyInfo); } } Everything was OK until I tried to delete some related objects (aggregate root object with two dependent objects which was marked for cascade deletion): I've got an exception "The relationship could not be changed because one or more of the foreign-key properties is non-nullable". I googled this and found http://blog.abodit.com/2010/05/the-relationship-could-not-be-changed-because-one-or-more-of-the-foreign-key-properties-is-non-nullable/ I changed GetHashCode to base.GetHashCode() and error disappeared. But now it breaks all my code: I can't override GetHashCode for my POCO objects = I can't override Equals = I can't implement Value Object and Entity Object patters for my POCO objects. So, I appreciate any solutions, workarounds here etc.

• C# Implementing a custom stream writer-esque class

  - by Luke

  How would I go about writing my own stream manipulator class? Basically what I'm trying to wrap my head around is storing the reference to the underlying stream in the writer. For example, when writing to a memory stream using a StreamWriter, when a Write() is made, the underlying memory stream is written to. Can I store the reference to an underlying stream without using pointers or unsafe code? Even if it was just a string I wanted to "write" to. Really this has little to do with stream writers, and I'm just wondering how I could store references in a class. The StreamWriter was the best example I could come up with for this.

• Deserializing JSON into an object with Json.NET

  - by hmemcpy

  Hello. I'm playing a little bit with the new StackOverflow API. Unfortunately, my JSON is a bit weak, so I need some help. I'm trying to deserialize this JSON of a User: {"user":{ "user_id": 1, "user_type": "moderator", "creation_date": 1217514151, "display_name": "Jeff Atwood", ... "accept_rate": 100 }} into an object which I've decorated with JsonProperty attributes: [JsonObject(MemberSerialization.OptIn)] public class User { [JsonProperty("user_id", Required = Required.Always)] public virtual long UserId { get; set; } [JsonProperty("display_name", Required = Required.Always)] public virtual string Name { get; set; } ... } I get the following exception: Newtonsoft.Json.JsonSerializationException: Required property 'user_id' not found in JSON. Is this because the JSON object is an array? If so, how can I deserialize it to the one User object? Thanks in advance!

• Resolve dependency with autofac based on constructor parameter attribute

  - by Andrew Davey

  I'm using AutoFac. I want to inject a different implementation of a dependency based on an attribute I apply to the constructor parameter. For example: class CustomerRepository { public CustomerRepository([CustomerDB] IObjectContainer db) { ... } } class FooRepository { public FooRepository([FooDB] IObjectContainer db) { ... } } builder.Register(c => /* return different instance based on attribute on the parameter */) .As<IObjectContainer>(); The attributes will be providing data, such as a connection string, which I can use to instance the correct object. How can I do this?

• Delphi: Get MAC of Router

  - by Daniel Marschall

  Hello, I am using Delphi and I want to determinate the physical MAC address of a network device in my network, in this case the Router itself. My code: var idsnmp: tidsnmp; val:string; begin idsnmp := tidsnmp.create; try idsnmp.QuickSend('.1.3.6.1.2.1.4.22.1.2', 'public', '10.0.0.1', val); showmessage(val); finally idsnmp.free; end; end; where 10.0.0.1 is my router. Alas, QuickSend does always send "Connection reset by peer #10054". I tried to modify the MIB-OID and I also tried the IP 127.0.0.1 which connection should never fail. I did not find any useable Tutorials about TIdSNMP at Google. :-( Regards Daniel Marschall

Any suggestions? Thanks!

• postgres - remove whitespace from field?

  - by n00b0101

  I imported a bunch of data using pgloader, and am now seeing that there's a bunch of whitespace (both spaces and tabs) inside of the fields. Is there a way to quickly update the fields to remove it from the beginning, the end, and the middle? I know there's TRIM, but that won't work for me... As an added problem... I only want to remove double spaces and replace it with a single space, but there might be 5 or 6 spaces in a row, and I'd prefer not to have to rerun a replace query until they're all ok? I was looking at regex_replace, but, I'm not sure how to make certain that it removes it from the middle of a string as well...
