  Hi, In Python script,for every method definition in some C++ code of the form: return_value ClassName::MethodName(args) {MehodBody} ,I need to extract three parts: the class name, the method name and the method body for further processing.

• Creating multiple objects of a view defined in the xml

  - by user362953

  I have to dynamically add a list of views (the views use RelativeLayout). Can I do this by specifying the view definition in xml and instantiate multiple objects off it? This gives the usual benefits of separating the view part from the code (for e.g., making it easy for the UI guys to alter things) or Is going the ArrayAdapter the suggested/only route?

• can the web.config be changed so roles wouldn't work any more?

  - by Scott J.

  I have had two instances of this problem, first on my local computer, now on the main site. Users can log in to the site, but it doesn't seem to recognize their roles. When I log in (which the database still recognizes as having the role admin), the code does not recognize it as being in the admin role. If there are other web.configs in subfolders, would that cause the problem? What could possibly cause this issue? Thanks! scojomodena

• Does Math.Sqrt cache its own results?

  - by Jonathan Beerhalter

  Someone has suggested to me that the built in C# Math.Sqrt function in .NET 4.0 caches its results, so that if I call Math.Sqrt(50) over and over again, it's not actually doing a sqrt, but just pulling the answer from a cache. Can anyone verify or deny this claim? If it's true then I have a bunch of needless caching going on in my code.

• Business object and linq2SQL

  - by Overdose

  What is the optimal way to write the code which interacts with DB using linq2SQL? I need to add some business logic to the entities. So I guess there are two ways: Write some wrapper class. The main minus is that many fields are the same, so i don't feel it as DRY style. Add business logic methods to linq2sql entities(these classes are partial) directly ???

• Is it the best practice to extract an interface for every class?

  - by the_drow

  I have seen code where every class has an interface that it implements. Sometimes there is no common interface for them all. They are just there and they are used instead of concreate objects. They do not offer a generic interface for two classes and are specific to the domain of the problem that the class solves. Is there any reason to do that?
