I'm trying to get my first entry level programmer job but am finding it tough out there.......How did other people get there first jobs in programming?

  • how do i know how many clients are calling my WCF service function

    - by ZhengZhiren
    i am writing a program to test WCF service performance in high concurrency circumstance. On client side, i start many threads to call a WCF service function which returns a long list of data object. On server side, in that function called by my client, i need to know the number of clients calling the function. For doing that, i set a counter variable. In the beginning of the function, i add the counter by 1, but how can i decrease it after the funtion has returned the result? int clientCount=0; public DataObject[] GetData() { Interlocked.Increment(ref clientCount); List<DataObject> result = MockDb.GetData(); return result.ToArray(); Interlocked.Decrement(ref clientCount); //can't run to here... } i have seen a way in c++. Create a new class named counter. In the constructor of the counter class, increase the variable. And decrease it in the destructor. In the function, make a counter object so that its constructor will be called. And after the function returns, its destructor will be called. Like this: class counter { public: counter(){++clientCount; /* not simply like this, need to be atomic*/} ~counter(){--clientCount; /* not simply like this, need to be atomic*/} }; ... myfunction() { counter c; //do something return something; } In c# i think i can do so with the following codes, but not for sure. public class Service1 : IService1 { static int clientCount = 0; private class ClientCounter : IDisposable { public ClientCounter() { Interlocked.Increment(ref clientCount); } public void Dispose() { Interlocked.Decrement(ref clientCount); } } public DataObject[] GetData() { using (ClientCounter counter = new ClientCounter()) { List<DataObject> result = MockDb.GetData(); return result.ToArray(); } } } i write a counter class implement the IDisposable interface. And put my function codes into a using block. But it seems that it doesn't work so good. No matter how many threads i start, the clientCount variable is up to 3. Any advise would be appreciated.

  • SOAP WCF Webservice behaves differently when called locally or remotely

    - by Idriss
    I have a WCF SOAP 1.1 Webservice with the configuration specified below. A concurrent call to any method of this endpoint hangs until the other returns when called remotely (from another computer on the network). I cannot replicate this when these methods are called locally (with a client located on the same machine). I tried to increase the maxConcurrentCalls with no luck ... the service behavior seems to be different according to the client local/remote location. Any guess? Thanks, <?xml version="1.0" encoding="utf-8"?> <configuration> <system.serviceModel> <services> <service behaviorConfiguration="MyCustomBehavior" name="CONTOSO.CONTOSOServerApi.IContosoServiceApiImplV1"> <endpoint address="" binding="customBinding" bindingConfiguration="WebBinding" bindingNamespace="http://contoso.com" contract="CONTOSO.CONTOSOServerApiInterfaceV1.IContosoServiceApiV1" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="MyCustomBehavior"> <serviceMetadata httpGetEnabled="true" httpGetUrl="http://localhost:8080/MyEndPointV1" /> <serviceDebug httpHelpPageEnabled="false" includeExceptionDetailInFaults="true" /> <serviceThrottling maxConcurrentSessions="10000" maxConcurrentCalls="1000"/> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <customBinding> <binding name="WebBinding"> <textMessageEncoding messageVersion="Soap11" maxReadPoolSize="2147483647" maxWritePoolSize="2147483647"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> </textMessageEncoding> <httpsTransport /> </binding> </customBinding> </bindings> </system.serviceModel> </configuration>

  • TeamCity build number independent artifacts

    - by Stanislav Shevchenko
    Hello, My TeamCity's nightly build produces more than 130Mb java doc as Build Configuration artifact. I have to share these artifact for other teams(developers), but javadoc every time has another one URL(I know that it's possible to get it like .lastFinished), and get's new place on Build Machine. Is it possible on each build replace old artifact with new one because I don't need need previous versions? And have independent from build version URL for accessing.

  • Can an algorithmic process ever give true random numbers ?

    - by Arkapravo
    I have worked with random functions in python,ruby, MATLAB, Bash and Java. Nearly every programming language has a function to generate Random numbers. However, these apparently random sequences are termed as pseudo-random number sequences as the generation follows a deterministic approach, and the sequence seems to repeat (usually with a very large period). My question, can an algorithmic/programming process ever yield true random numbers ? The questions probably is more of theoretical computer science than just programming !

  • What kind of cost does Symbian require?

    - by httpinterpret
    Quoted from this answer: Cost of tools: JavaME would be cheapest, followed by Symbian, Android then iPhone. I want to get started with mobile phone programing,but I don't see where Symbian does cost, as its SDK is available for free. Anyone knows? BTW,many people say Symbian only supports Symbian C++, but after reading its document, it seems it also support Java, is this feature newly added?

Though the client has written down the data in a socket. The header is readed and decoded successfully. What's the error?

  • How do I use Entity Framework in a CLR stored procedure?

    - by Ivan
    I am looking forward to move all the logic (which is implemented as manipulating Entity Framework 4 objects) to a server side. It looks going to be simple (thanks to the application structure) and beneficial (as all I have is one oldy laptop as a client and one tough server which runs SQL Server 2008, and building a separate service for the logic can just introduce more latency if compared to doing it inside the database). So how do I correctly use Entities Framework inside a CLR stored procedure and make it using a host-server-provided SqlContext?

  • Best programming language for a beginner to learn?

    - by Dean
    I am teaching my friend how to program in C, he has no programming experience. He wants to learn C so that he can program different microprocessors. I have suggested he learn another language something like java or ruby so that he can learn basics before moving on to a language like C. Is this advisable or should i just teach him C?

  • Tool to monitor HTTP, TCP, etc. Web Service traffic

    - by huseyint
    What's the best tool that you use to monitor Web Service, SOAP, WCF, etc. traffic that's coming and going on the wire? I have seen some tools that made with Java but they seem to be a little crappy. What I want is a tool that sits in the middle as a proxy and does port redirection (which should have configurable listen/redirect ports). Are there any tools work on Windows to do this?

  • Is it possible to keep mysql migration running without keeping connection open?

    - by taw
    ALTER TABLE can easily take a few days - and during this time there's a non-negligible chance of connection getting terminated due to network problems. Is it possible to start ALTER TABLE (or CREATE TABLE ... SELECT ...; or some other very long running query) and leave it running without keeping connection open all the time? (the obvious solution of screen + console mysql client won't easily work as there's no ssh running on that server, only mysqld).

  • Print/save full webpage as PDF

    - by Oliver
    I need a method to be able to print/save the current full webpage as a PDF. I know it can be done if I download a PDF printer and print to that; but I need it to be done without the user having to do anything other than click a button in a webpage. I can't do it via PHP as the page is all client side content, so I'm guessing an ActiveX component? Any ideas would be greatly appreciated! Many thanks

  • Is there a performance hit when running obfuscated code?

    - by nvivek
    All, I am proposing the addition of code obfuscation to the standard build process at my organization. One of the questions being asked is whether there is a performance hit to running obfuscated code vs. running unobfuscated code. What is your experience? Have you seen a reduction in performance at runtime because you obfuscated your Java or C# code? Thanks, VI
