  • WCF DTO versions

    - by cvista
    Hi I have some services at the moment that return a dto with the following fields: [DataMember] public int Id { get; set; } [DataMember] public string Name { get; set; } and I want to add more to this service by adding the following properties: [DataMember] public virtual DateTime StartDate { get; set; } I'm not in a position where i can update the consumers of these services though - the client does that themselves. My question is - will the old clients be able to just skip these new properties? and the new ones take advantage of them or will the serialization be an issue with the new properties? w://

  • IDE underlining custom attributes

    - by runrunraygun
    I have a custom attribute... [System.AttributeUsage(System.AttributeTargets.All)] public class Refactor : System.Attribute { private string _message; public Refactor() { _message = string.Empty; } public Refactor(string message) { _message = message; } } Applied to [Refactor("this should be less rubbish")] public virtual void RubbishMethod() { … } Now when someone makes a call to RubbishMethod I'd like the IDE (vs2008) to underline that call in a deep brown colour, similar to if I mark as Obsolete you get a green wave line. Is this possible? I've been racking my brain and hitting the google but I can't find how and where to do this.

  • Change Casing in WCF Service Reference

    - by Eric J.
    I'm creating a service reference to a web service written in Java. The generated classes now follow the Java casing convention used in the web service, for example class names are camelCase rather than PascalCase. Is there a way to get the desired casing from the service reference? CLARIFICATION: With WSE based services, one could modify the generated Reference.cs to provide .NET standard casing and use XmlElementAttribute to map to the Java naming presented by the external web service, like this: [System.Xml.Serialization.XmlElementAttribute("resultType", Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] [System.Runtime.Serialization.DataMember] public virtual MyResultType ResultType { ... } Not terribly maintenance-friendly without writing custom code to either generate the proxy code or modify it after it's been generated. What I'm after is one or more options to present a WCF generated client proxy to calling applications using the .NET casing conventions, achieving the same as I did previously with WSE. Hopefully with less manual effort.

  • How to structure a Genetic Algorithm class hierarchy?

    - by MahlerFive
    I'm doing some work with Genetic Algorithms and want to write my own GA classes. Since a GA can have different ways of doing selection, mutation, cross-over, generating an initial population, calculating fitness, and terminating the algorithm, I need a way to plug in different combinations of these. My initial approach was to have an abstract class that had all of these methods defined as pure virtual, and any concrete class would have to implement them. If I want to try out two GAs that are the same but with different cross-over methods for example, I would have to make an abstract class that inherits from GeneticAlgorithm and implements all the methods except the cross-over method, then two concrete classes that inherit from this class and only implement the cross-over method. The downside to this is that every time I want to swap out a method or two to try out something new I have to make one or more new classes. Is there another approach that might apply better to this problem?

  • Can't read from aspnet_client folder for crystal reports

    - by Hank Allen
    I created a little ASP .Net app to run Crystal Reports. It runs fine from VS 2008 but not when deployed to IIS on Windows 7. The toolbar images are not rendered. The problem seems to be I can't read from the aspnet_client folder even though I've made into a virtual directory. I can't even read images I put in there just to see if the folder can be read from an ASP page. I also made sure the IIS user can read from there. I'm stumped.

  • Reflecting derived classes in C#

    - by rook
    Let's assume there's a class with a virtual property (let's call it 'P'). It's overridden in a deriving class. Now I want to use something like this: obj.GetType().GetProperty("P") to get info about the overriding property. This search is ambigous, because there are two "P" properties (base and override). So I typed: obj.GetType().GetProperty("P", BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance) It returns the overriding "P" only, but what if I can't guess in compile time if there's an override at all? The latter call would return null. The case is even more complicated, if the hierarchy of inheritance is bigger. In other words, I want to get the 'top-most' override available, otherwise - the base property. What is the cleanest way to achieve the aim? Only one I know at the moment is to go through all properties and check name and declaring type.

  • Why is OnDragEnter not called?

    - by Harvey
    I have added the COleDropTarget variable to my view class, Registered it in the OnCreate(), which is being called at startup. I added the OnDragEnter and OnDrop virtual functions (not the others yet, as OnDragLeave). But they are not called when I drag (or drop) a piece of text over them. I just happened to think about the fact that I had already implemented the dropfiles function to the same window. Is this preventing the text drag? What else do I need? TIA, Harvey

  • Tomcat IIS 7 Integration gives 503 errors on all requests.

    - by Yvan JANSSENS
    Hi, After many attempts to install Tomcat on IIS 7, I finally managed to get it working. At least I think so :-S. I finally got the 500 errors away, by setting the correct permissions.

  • Java RS232 Comm on Vista-64 bit

    - by DD
    We have a Java application which needs to communicate with a peripheral device over Virtual Serial COM port. We use the RS232 Java COMM API (javax.comm.properties, comm.jar, win32com.dll) to achieve the same. Currently the code works fine on Windows XP 32-bit, Vista 32-bit and Windows 7. However we are having a problem trying to communicate on Vista 64-bit. I read from the Java forums that there is no 64-bit support for the Java COMM API I was wondering if anyone was facing a similar situation and were able to resolve the same in some way?

  • How Moles Isolation framework is implemented?

    - by Buu Nguyen
    Moles is an isolation framework created by Microsoft. A cool feature of Moles is that it can "mock" static/non-virtual methods and sealed classes (which is not possible with frameworks like Moq). Below is the quick demonstration of what Moles can do: Assert.AreNotEqual(new DateTime(2012, 1, 1), DateTime.Now); // MDateTime is part of Moles; the below will "override" DateTime.Now's behavior MDateTime.NowGet = () => new DateTime(2012, 1, 1); Assert.AreEqual(new DateTime(2012, 1, 1), DateTime.Now); Seems like Moles is able to modify the CIL body of things like DateTime.Now at runtime. Since Moles isn't open-source, I'm curious to know which mechanism Moles uses in order to modify methods' CIL at runtime. Can anyone shed any light?

  • iOS Efficiency File Saving Efficiency

    - by Guvvy Aba
    I was working on my iOS app and my goal is to save a file that I am receiving from the internet bit by bit. My current setup is that I have a NSMutableData object and I add a bit of data to it as I receive my file. After the last "packet" is received, I write the NSData to a file and the process is complete. I'm kind of worried that this isn't the ideal way to do it because of the limitations of RAM in a mobile device and it would be problematic to receive large files. My next thought was to implement a NSFileHandle so that as the file arrives, it would be saved to the disk, rather than the virtual memory. In terms of speed and efficiency, which method do you think will work decently on an iOS device. I am currently using the first, NSMutableData approach. Is it worth changing my app to use the NSFileHandle? Thanks in advance, Guvvy

    Hi, I am using CI + Doctrine + MySQL and I am getting the following CRUD errors: (1) When trying to create a new record in the database with this code: $book_title = 'The Peloponnesian War'; $b = new Book(); $b-title = $book_title; $b-price = 10.50; $b-save(); I get this error: Fatal error: Uncaught exeption 'Doctrine_Connection_Mysql_Exception' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'title' in 'field list' in ...

And finally, when I try to update a record as follows: $book_title = 'The Peloponnesian War'; $title = $book_title; $u = Doctrine::getTable('Book')-find($title); $u-title = $title; $u-save(); I get a similar error: Fatal error: Uncaught exception 'Doctrine_Connection_Mysql_Exception' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'b.id' in 'field list''in ... Here is my Doctrine_Record model: class Book extends Doctrine_Record{ public function setTableDefinition() { $this->hasColumn('book_id'); $this->hasColumn('isbn10','varchar',20); $this->hasColumn('isbn13','varchar',20); $this->hasColumn('title','varchar',100); $this->hasColumn('edition','varchar',20); $this->hasColumn('author_f_name','varchar',20); $this->hasColumn('author_m_name','varchar',20); $this->hasColumn('author_l_name','varchar',20); $this->hasColumn('cond','enum',null, array('values' => array('as new','very good','good','fair','poor'))); $this->hasColumn('price','decimal',8, array('scale' =>2)); $this->hasColumn('genre','varchar',20); } public function setUp() { $this->setTableName('Book'); //$this->actAs('Timestampable'); } Any assistance will be really appreciated. Thanks in advance.

  • Hiding Row in DataGridView Very Slow

    - by Ed Schwehm
    I have a DataGridView in a Winforms app that has about 1000 rows (unbound) and 50 columns. Hiding a column takes a full 2 seconds. When I want to hide about half the rows, this becomes a problem. private void ShowRows(string match) { this.SuspendLayout(); foreach (DataGridViewRow row in uxMainList.Rows) { if (match == row.Cells["thisColumn"].Value.ToString())) { row.Visible = false; } else { row.Visible = true; } } this.ResumeLayout(); } I did some testing by adding by addingConsole.WriteLine(DateTime.Now)around the actions, androw.Visible = falseis definitely the slow bit. Am I missing something obvious, like setting IsReallySlow = false? Or do I have to go ahead and enable Virtual Mode and code up the necessary events?

  • How can I set up a fault-tolerant web-service built with Erlang/OTP?

    - by Jonas
    I would like to setup a fault-tolerant web-service. I will build the web-service with Erlang/OTP. At the beginning the web-service will be hosted on a few VPS. Each VPS has its own IP-address, and I can use more if IPs if I need. I would like to have the domain name pointing to a single IP-address. How can setup my Erlang/OTP-application to be fault-tolerant behind a single IP-address? Do I need to use VLAN? Is there a way my Erlang/OTP-application can use heartbeats and handle virtual IP-addresses to route the traffic? or how should I solve this problem?

  • Troubleshooting source of heavy resource-usage on a server 2008 running multiple sites

    - by batman_man
    Hi, I am running about 10 asp.net websites on a hosted virtual server. The server runs Server 2008 - each website is backed by its own database running on SQL server 2008 on the same box. Lately the box has seemed really slow. The only kind of discovery i could think of doing was looking in the task manager, where i can see w3wp and sqlserver.exe jumping to 40% cpu usage every 5-10 seconds. What are the steps i can take to determine which of my websites is taking these resources and or what database is getting hit the most? I have of course ssms installed on the machine as well. As you can tell, my sysadmin skills are very very limited - any help would be much appreciated.

  • Lighttpd not cleanly restarting (address already in use)

    - by NilObject
    When doing a dist-upgrade recently, my lighttpd-1.4.19 install on Ubuntu 8.0.4 has begun failing to restart or reload properly with the /etc/init.d/lighttpd restart command. ~$ sudo /etc/init.d/lighttpd restart * Stopping web server lighttpd ...done. * Starting web server lighttpd 2009-06-13 04:06:36: (network.c.300) can't bind to port: 80 Address already in use ...fail! The same error occurs when I do a reload. The way I get around it is to kill lighttpd and then issue the start command, but it seems like I shouldn't have to do that :) I've looked at my config files, and can't spot any immediate errors. Does anyone have any ideas what can be causing this error? This seems to be the latest version as of writing this question that is available via the apt-get route.

  • synchronizing audio over a network

    - by sharkin
    I'm in startup of designing a client/server audio system which can stream audio arbitrarily over a network. One central server pumps out an audio stream and x number of clients receives the audio data and plays it. So far no magic needed and I have even got this scenario to work with VLC media player out of the box. However, the tricky part seems to be synchronizing the audio playback so that all clients are in audible synch (actual latency can be allowed as long as it is perceived to be in sync by a human listener). My question is if there's any known method or algorithm to use for these types of synchronization problems (video is probably solved the same way). My own initial thoughts centers around synchronizing clocks between physical machines and thereby creating a virtual "main timer" and somehow aligning audio data packets against it. Some products already solving the problem: http://www.sonos.com http://netchorus.com/ Any pointers are most welcome. Thanks. PS: This related question seem to have died long ago.

  • Why is there ambiguity in this diamond pattern?

    - by cambr
    #include <iostream> using namespace std; class A { public: void eat(){ cout<<"A";} }; class B: public A { public: void eat(){ cout<<"B";} }; class C: public A { public: void eat(){ cout<<"C";} }; class D: public B,C { public: void eat(){ cout<<"D";} }; int main(){ A *a = new D(); a->eat(); } I am not sure this is called diamond problem or not, but why doesn't this work? When I said, a->eat() (remember eat() is not virtual), there is only one possible eat() to call, that of A. Why then, do I get this error: 'A' is an ambiguous base of 'D'

  • php if clause inside foreach not retrieving data correctly

    - by Mike
    Here's my issue: In my controller, I want to grab user input from a form. I then parse the input, and compare it to database values to ensure I'm grabbing the correct input. I simply want to match the user's answers to the question, grab the user ID, the question ID, and then determine if the answer applies to a multiple choice or checkbox question, or something else. I take those values and insert them into the answer table. Ignore the waiver stuff. I'll test that once I get the answers input correctly. // add answers and waiver consent records try { $answerArray = array(); $waiverArray = array(); // retrieve answers, waiver consents, and the question ID's from form object foreach ($formData as $key => $value) { $parts = explode("_", $key); if ($parts[0] == 'question') { array_push($answerArray, $value); } if ($parts[0] == 'waiverTitle') { array_push($waiverArray, $value); } } $questions = new Model_DbTable_Questions(); $questionResults = $questions->getQuestionResults($session->idEvent); foreach ( $questionResults as $qr ) { if ($qr ['questionType'] == 'multipleChoice' || $qr ['questionType'] == 'checkBox') { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], null, $aa ); echo count ( $answerData ) . ', ' . $qr ['questionType'] . ', ' . $aa . '<br />'; } } else { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], $aa, null ); echo count ( $answerData ) . ', ' . $qr ['questionType'] . ', ' . $aa . '<br />'; } } } } catch (Zend_Db_Statement_Exception $e) { $e->getMessage(); throw $e; } From my test data, I expect to get 2 records that match the multiple choice and checkbox criteria, and 1 record for text in the ELSE clause like this: 3, checkbox, 1 3, multipleChoice, 1 3, text, question_2 What I get is a 3x3 Cartesian product, 3 question elements each with the 3 possible answers like this output from the echo statements: 4, checkBox, 1 4, checkBox, 1 4, checkBox, question_2 4, multipleChoice, 1 4, multipleChoice, 1 4, multipleChoice, question_2 4, text, 1 4, text, 1 4, text, question_2 I've tried placing the IF clause inside the inner foreach, but I get the same results. I've been staring at this problem for way too long and cannot see what I'm doing wrong. Your kind assistance would be greatly appreciated. Please let me know if my request requires more clarification.

  • fluent nhibernate m-to-m with column

    - by csetzkorn
    Hi, I am used to hbm files and started using fluent nhibernate recently. Creating an m-to-m relationship between two entities A and B is quite simple In A I create: public virtual IList Bs { get; set; } and then I use: mapping.HasManyToMany(x = x.Bs); That’s it and I can do: A a = new A(); a.Bs.Add(b); My problem is that I would like to have an additional column in my dedicated m-to-m database table which holds the two foreign keys. What is the simplest way to achieve this in FNH? Would I have to create a dedicated entity for the m-to-m realtionship or is there a simpler solution? Thanks. Best wishes, Christian
