  • Creating Instance of a DataContract Class on the client side

    - by hgulyan
    I'm not sure, if it's right to do this, but I'd like to ask this question again ( http://stackoverflow.com/questions/2498644/creating-instance-of-a-service-side-datacontract-class-on-client-side-in-wcf ). The main question is - why there's difference between creating instance on the client side and creating it on the server side? Why there're some properties, that lose their values when you create them on the client side and pass it to service's functions? What could be the issue? Any version will be appreciated. I've written about my problem in the update part of the question in that link. Thank You. p.s. If this is against the rules, I'll delete it.

  • Best method to compress JSON string in term of performance and compress radio

    - by Eric Yin
    For a JSON string, contains all kinds of settings, numbers, string etc. Total JSON string fairly fall into 10k~50K range. I want to compress it before save to database. So I wonder which compress method should I choose, I am using c# 4, I know I can choose gzip and deflate but the compression radio is not good (although speed is good). More specific, compress can be a little slow (since only once) but should be small. Decompress should be lighting fast since decompress happens lots. Please give some advice.

  • Is my form password being passed in clear text?

    - by liinkas
    This is what my browser sent, when logging into some site: POST http://www.some.site/login.php HTTP/1.0 User-Agent: Opera/8.26 (X2000; Linux i686; Z; en) Host: www.some.site Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1 Accept-Language: en-US,en;q=0.9 Accept-Charset: iso-8859-1, utf-8, utf-16, *;q=0.1 Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0 Referer: http://www.some.site/ Proxy-Connection: close Content-Length: 123 Content-Type: application/x-www-form-urlencoded lots_of_stuff=here&e2ad811=my_login_name&e327696=my_password&lots_of_stuff=here Can I state that anyone can sniff my login name and password for that site? Maybe just on my LAN? If so (even only on LAN ) then I'm shocked. I thought using <input type="password"> did something more than make all characters look like ' * ' p.s. If it matters I played with netcat (on linux) and made connection browser <= netcat (loged here) <= proxy <= remote_site

  • Inherit from Type class of .Net

    - by Miguel Angelo
    Is there any point at all on inheriting from Type class in .Net? i.e. What could be the meaning of doing so? I am asking this because of this text in MSDN documentation: Notes to Inheritors When you inherit from Type, you must override the following members... list of members. MSDN doc for Type: http://msdn.microsoft.com/en-us/library/system.type.aspx ok, that is actually saying that anyone can inherit from Type... but they dont say why would you ever want to do that. Thanks!

  • Looking for the most painless non-RDBMS storage method in C#

    - by NateD
    I'm writing a simple program that will run entirely client-side. (Desktop programming? do people still do that?) and I need a simple way to store trivial amounts of data in a structured form, but really don't see any need to use a database system. What's more, some of the data needs to be serialized and passed around to different users, like some kind of "file" or perhaps a "document". (has anyone ever done that before?) So, I've looked at using .Net DataSets, LINQ, direct XML manipulation, and they all seem like they would get the job done, but I would like to know before I dive into any of them if there's one method that is generally regarded as easier to code than others. As I said, the amount of data to be stored is trivial, even if one hundred people all used the same machine we're not talking about more than 10 MB, so performance is not as large a concern as is codeability/maintainability. Thank you all in advance!

  • Basic Java Multi-Threading Question

    - by Veered
    When an object is instantiated in Java, is it bound to the thread that instantiated in? Because when I anonymously implement an interface in one thread, and pass it to another thread to be run, all of its methods are run in the original thread. If they are bound to their creation thread, is there anyway to create an object that will run in whatever thread calls it?

  • Assigning to struct in different class

    - by 4thSpace
    I have a struct in ClassA and want to assign it to the same struct in ClassB (the two structs are the same with different names). ClassA and ClassB are view controllers. Basically, I need to pass this struct to another class. However, structs don't seem to be exposed as members, which means I can't access them. Here is ClassA's struct declared in its header file: typedef struct { NSString *startDate; NSString *endDate; NSString *classId; } selectedItemsClassAStruct; selectedItemsClassAStruct selectedItemsClassA; and the same for ClassB (just with ClassA text replaced) It doesn't appear in code hints for ClassB. I see this error if I try to access it: request for member 'selectedItemsClassBStruct' in something not a structure or union How should it be done?

  • Use super class's address/pointer in initialization list

    - by JQ
    context 1: class D : public B1, public B2{}; context 2: B2 takes B1 to initialize: B2( B1 * ) //B2's constructor my question is in D's initialization list: D::D() : B1(), B2( ? )... What should be in ? I don't want to put " (B1*)this " in the ? place, because it's no good to use "this" in initialization list. And since B1 part has been initialized, it makes sense to use it. What should I do ?

  • Garbage collection of Strings returned from C# method calls in ascx pages

    - by Icarus
    Hi, For a web application developed on ASP.NET, we are finding that for user control files (ascx) we are returning long strings as a result of method calls. These are embedded in the ascx pages using the special tags <% %> When performing memory dump analysis for the application, we find that many of those strings are not being garbage collected. Also, the ascx pages are compiled to temporary DLLs and they are held in memory. Is this responsible for causing the long strings to remain in memory and not be garbage collected ? Note : The strings are larger than 85K in size.

  • adldap class, need to search for user in two groups

    - by Brad
    http://adldap.sourceforge.net/wiki/doku.php?id=api_user_functions#user_ingroup_username_group_recursive_null I am using the adLDAP class above to authenticate users against our ldap server. I was wondering how I could check multiple groups to see if the user belongs to either, if they belong to either. I don't know if user_ingroup($username,$group,$recursive=NULL); can handle search two different groups for the user, need help coding it to search for the user in two different groups, and as soon as it finds it in one of those, break the operation and set a variable to true. Any help is appreciated.

  • F#: Define an abstract class that inherits an infterface, but does not implement it

    - by akaphenom
    I owuld like to define an abstract class that inerhits from UserControl and my own Interface IUriProvider, but doesn't implement it. The goal is to be able to define pages (for silverlight) that implement UserControl but also provide their own Uri's (and then stick them in a list / array and deal with them as a set: type IUriProvider = interface abstract member uriString: String ; abstract member Uri : unit -> System.Uri ; end type UriUserControl() as this = inherit IUriProvider with abstract member uriString: String ; inherit UserControl() Also the Uri in the definition - I would like to implement as a property getter - and am having issues with that as well. this does not compile type IUriProvider = interface abstract member uriString: String with get; end Thank you...

  • Mono - Uri class

    - by Jonathan.Peppers
    I am making an HttpWebRequest at a url similar to this: "http://mysite.com/search?query=my+search+string" Problem is, the Uri class escapes it with %, and the site I'm making the request against can't handle the escaped characters. (I have no control to fix the site) So tried this [Obsolete] constructor: new Uri(myUriString, true); But it did not seem to make any difference, when debugging, my Uri still got escaped. I am running this on a Mac with Mono, but I have not tried it on standard .Net on Windows to see if it has the same behavior. Is there another way to get around this issue?

  • Is it possible to overwrite a static method in parent class?

    - by MartinDenny2069
    I have a static method defined in a base class, I want to overwrite this method in its child class, is it possible? I tried this but it did not work as I expected. When I created an instance of class B and invoke its callMe() method, the static foo() method in class A is invoked. public abstract class A { public static void foo() { System.out.println("I am base class"); } public void callMe() { foo(); } } Public class B { public static void foo() { System.out.println("I am child class"); } }

  • Better way to clean this messy bool method

    - by Luís Custódio
    I'm reading Fowler Clean Code book and I think that my code is a little messy, I want some suggestions: I have a simple business requirement that is return the date of new execution of my Thread. I've two class fields: _hour and _day. If actual day is higher than my _day field I must return true, so I'll add a month to "executionDate" If the day is the same, but the actual hour is higher than _hour I should return true too. So I did this simple method: private bool ScheduledDateGreaterThanCurrentDate (DateTime dataAtual) { if (dateActual.Day > _day) { return true; } if (dateActual.Day == _day && dateActual.Hour > _hour) { return true; } if (dateActual.Day == _day && dateActual.Hour == _hour) if (dateActual.Minute>0 || dateActual.Second>0) return true; return false; } I'm programming with TDD, so I know that the return is correct, but this is bad maintain code right?

  • Ambiguous Generic restriction T:class vs T:struct

    - by Maslow
    This code generates a compiler error that the member is already defined with the same parameter types. private T GetProperty<T>(Func<Settings, T> GetFunc) where T:class { try { return GetFunc(Properties.Settings.Default); } catch (Exception exception) { SettingReadException(this,exception); return null; } } private TNullable? GetProperty<TNullable>(Func<Settings, TNullable> GetFunc) where TNullable : struct { try { return GetFunc(Properties.Settings.Default); } catch (Exception ex) { SettingReadException(this, ex); return new Nullable<TNullable>(); } } Is there a clean work around?

  • what pattern to use for multi-argument method?

    - by Omid S
    I have a method with the following signature: foo (Sample sample, Aliquot aliquot) "foo" needs to alter a Sample object, either the first argument or from the second argument it can extract its Sample. For example: foo (Sample sample, Aliquot aliquot) { Sample out = null; if (sample != null) out = sample else out = aliquot.getSample() return out; } But that is so un-elegant, other than reading the API a developer does not know the reference of the first argument overrides the Sample of the second argument. Now, I could change "foo" to foo (SomeMagicalObject bar) where SomeMagicalObject is a tuple for Sample and Aliquot and holds some logic ... etc. But I am wondering, are there some patterns for this question?

  • How can I interrupt a ServerSocket accept() method?

    - by lukeo05
    Hi, In my main thread I have a while(listening) loop which calls accept() on my ServerSocket object, then starts a new client thread and adds it to a Collection when a new client is accepted. I also have an Admin thread which I want to use to issue commands, like 'exit', which will cause all the client threads to be shut down, shut itself down, and shut down the main thread, by turning listening to false. However, the accept() call in the while(listening) loop blocks, and there doesn't seem to be any way to interrupt it, so the while condition cannot be checked again and the program cannot exit! Is there a better way to do this? Or some way to interrupt the blocking method? Thanks!

  • Recording object method calls to generate automated test.

    - by Constantin
    I have an object with large interface and I would like to record all its method calls done during a user session. Ideally this sequence of calls would be available as source code: myobj.MethodA(42); myobj.MethodB("spam", false); ... I would then convert this code to a test case to have a kind of automated smoke/load test. WCF Load Test can do this for WCF services and CodedUI test recorder can do this for UIs. What are my options for a POCO class? I am in position to edit application code and replace the object in question with some recording/forwarding proxy.
