  • Mock dll methods for unit tests

    - by sanjeev40084
    I am trying to write a unit test for a method, which has a call to method from dll. Is there anyway i can mock the dll methods so that i can unit test? public string GetName(dllobject, int id) { var eligibileEmp = dllobject.GetEligibleEmp(id); <---------trying to mock this method if(eligibleEmp.Equals(empValue) { .......... } }

  • Exception handling protocol for methods

    - by athena
    Is there any specific protocol for handling exceptions in public methods? Consider this eg. public int someMethod() { try{ code that might throw an exception } catch(Exception e) { log the exception } } Say that this method might throw an ArrayIndexOutOfBoundsException. So, is it correct to handle this Exception in the method itself (as in the example) or throw it and assume that the calling method will handle the Exception?

  • Finding the methods/properties on a swf object

    - by Jones
    I have a swf object embedded into a web page. Without having access to the source code of the swf file, how can I find the methods/properties that are exposed? For example... alert(document.getElementById('swfObject').id); ...returns a pop-up of "swfObject". And this... document.getElementById('swfObject').someMethod(); ...executes someMethod. Thanks.

  • Performance of Managed C++ Vs UnManaged/native C++

    - by bsobaid
    I am writing a very high performance application that handles and processes hundreds of events every millisecond. Is Unmanaged C++ faster than managed c++? and why? Managed C++ deals with CLR instead of OS and CLR takes care of memory management, which simplifies the code and is probably also more efficient than code written by "a programmer" in unmanaged C++? or there is some other reason? When using managed, how can one then avoid dynamic memory allocation, which causes a performance hit, if it is all transparent to the programmer and handled by CLR? So coming back to my question, Is managed C++ more efficient in terms of speed than unmanaged C++ and why?

  • Simple/Basic steganography algorithms and methods

    - by tomp
    What are the basic and simpliest steganography algorithms and methods? I mean the steganography applied to images. How does simple program that hides data to images work? How does the program recognize the encrypted message in image without the source image? What are the main techniques used?

  • Native Endians and Auto Conversion

    - by KnickerKicker
    so the following converts big endians to little ones uint32_t ntoh32(uint32_t v) { return (v << 24) | ((v & 0x0000ff00) << 8) | ((v & 0x00ff0000) >> 8) | (v >> 24); } works. like a charm. I read 4 bytes from a big endian file into char v[4] and pass it into the above function as ntoh32 (* reinterpret_cast<uint32_t *> (v)) that doesn't work - because my compiler (VS 2005) automatically converts the big endian char[4] into a little endian uint32_t when I do the cast. AFAIK, this automatic conversion will not be portable, so I use uint32_t ntoh_4b(char v[]) { uint32_t a = 0; a |= (unsigned char)v[0]; a <<= 8; a |= (unsigned char)v[1]; a <<= 8; a |= (unsigned char)v[2]; a <<= 8; a |= (unsigned char)v[3]; return a; } yes the (unsigned char) is necessary. yes it is dog slow. there must be a better way. anyone ?

  • What are some good code optimization methods?

    - by esac
    I would like to understand good code optimization methods and methodology. How do I keep from doing premature optimization if I am thinking about performance already. How do I find the bottlenecks in my code? How do I make sure that over time my program does not become any slower? What are some common performance errors to avoid (e.g.; I know it is bad in some languages to return while inside the catch portion of a try{} catch{} block

  • How to prevent inheritance for some methods?!

    Hi How can I prevent inheritance of some methods or properties in derived classes?! public class BaseClass : Collection { //Some operations... //Should not let derived classes inherit 'Add' method. } public class DerivedClass : BaseClass { public void DoSomething(int Item) { this.Add(Item); // Error: No such method should exist... } }

  • Add methods to generated WCF client proxy code

    - by dcstraw
    I'd like to add one additional method for each service operation in my WCF client proxy code (i.e. the generated class that derives from ClientBase). I have written a Visual Studio extension that has an IOperationContractGenerationExtension implementation, but this interface only seems to expose the ability to modify the service interface, not the ClientBase-derived class. Is there any way to generate new methods in the proxy client class?

  • javascript object's - private methods: which way is better.

    - by Praveen Prasad
    (function () { function User() { //some properties } //private fn 1 User.prototype._aPrivateFn = function () { //private function defined just like a public function, //for convetion underscore character is added } //private function type 2 //a closure function _anotherPrivateFunction() { // do something } //public function User.prototype.APublicFunction = function () { //call private fn1 this._aPrivateFn(); //call private fn2 _anotherPrivateFunction(); } window.UserX = User; })(); //which of the two ways of defining private methods of a javascript object is better way, specially in sense of memory management and performance.

  • Stateless singleton VS Static methods

    - by Sebastien Lorber
    Hey, Don't find any good answer to this simple question about helper/utils classes: Why would i create a singleton (stateless) rather than static methods? Why an object instance could be needed while the object has no state? Sometimes i really don't know what to use...

  • Best logging framework for native C++?

    - by Jox
    I'm looking for logging framework for C++ project. My best shoot was log4cxx, but it seems that it's abandoned project, with development stopped ~4 years ago, with only one update in last 4-5 years. Anything better that log4cxx? (log4c & log4cpp are also totally out-of-date)...

  • Get methods params type parsing wsdl file in a rails/ruby application

    - by Marco Sangiorgi
    Hi, I have a question about ruby and wsdl soap. I couldn't find a way to get each method's params and their type. For example, if I found out that a soap has a methods called "get_user_information" (using wsdlDriver) is there a way to know if this method requires some params and what type of params does it require (int, string, complex type, ecc..)? I'd like to be able to build html forms from a remote wsdl for each method... Sorry for my horrible English :D
