Could i use nonstatic members inside a static method?
eg.
$this->nonStaticProperty $this->nonStaticMethod()
and vice versa that is to say use static members inside non-static methods?

As a static member doesn't have.
Not really, as you can't use $this in a static context .

I'm writing a C++ class to read input from a file into preallocated buffers called "chunks".
I want the caller to be able to call a public static Chunk class method called GetNextFilledChunk() , which

As written in the CPP file you have declared a non-member function which is preceeded by a badly formed label.
It should be defined like this:
Chunk * Chunk of GetNextFilledChunk .
You're defining your member function wrong.

The problem:
I have a C++ class with gajillion (>100) members that behave nearly identically:
same type
in a function, each member has the same exact code done to it as other members, e.g. assignment from a map in a constructor where map key is same...

I have run into a problem with generics and new members. I wrote a generic class which operates on an object of type ObjectA. ObjectB derives from ObjectA and hides a few of ObjectA's members. When I supply the type of ObjectB as the type parameter to...

Any reason you're not using normal inheritance, with virtual/overridden methods?
Here's another example of... .
That's the members exposed by ObjectA .
The calls generated by the compiler are to the members it knows about at compile-time .

Hi,
I am not getting Why Size of Class with a member function is 1 byte..While member function is 4 bytes in the following example.
class Test { public: Test11() { int m = 0; }; }; int main() { Test t1; int J = sizeof(t1); int K = sizeof(t1.Test11());...

The function itself lives in the executable code region, and all instances of the same type... .
Only the class's data members (and possibly its vtable pointer, if it has one) affect its size.
The function itself is not actually stored in the class .

I'm using .net framework 3.5 SP1.

If that doesn't work, do the same thing, but remove from MSL as well .
Now you should be able to update model as usual .
Save and close, then reopen in the GUI.
Remove all references to that type from the CSDL.
Open your model as XML.

How can I do this? (The following code does NOT work, but I hope it explains the idea.)
class MyClass { .... private: int ToBeCalled(int a, char* b); typedef (MyClass::*FuncSig)(int a, char* b); int Caller(FuncSig *func, char* some_string); }
I want to...

Imagine an interface heirarchy like this:
public interface IAnimal { string Color { get; } } public interface ICat : IAnimal { }
In this case, ICat 'inherits' IAnimal's Color property.
Is it possible to add an attribute to the ICat's Color property, without...

If you want to associate some constant value with a class, here are two ways to accomplish the same goal:
class Foo { public: static const size_t Life = 42; }; class Bar { public: enum {Life = 42}; };
Syntactically and semantically they appear to be identical...

One difference is that the enum.
You've have to declare a separate member variable of enum type to take the address of it.
Well, if needed, you can take the address of a static const Member Value.
