GUI internals, looking for turorials
Category : Development Tools & Services

There are tons of resources on how to program using the APIs of various widget toolkits but I can't seem to find much in the way of a tutorial on how to create widget toolkits themselves or how they work n detail. They are basically just black boxes to me right now.

a quick, simple question from me about for-loops.

Designer to see internals?
Category : Programming Languages

I have my signed assemblies here, in one of them I have a picture in the resources.
The other one is granted to use it as it's own, so my other assembly can reference the picture, and everything works fine.

Only if it wouldn't be for the Form Designer in VS2008.

Does LINQ to SQL work in connected environment or disconnected environment? I mean if you compile the query it builds expression query and the query is sent down to sql server ,there it is translated into T-SQL statement and executed and the final result is sent back to the C# code.I hope it is working in connected environment.Is there any framework operates LINQ to SQL in disconnected fashion?

Inheritance in C++ internals
Category : C & C++ & C#

Can some one explain me how inheritance is implemented in C++ ?

Does the base class gets actually copied to that location or just refers to that location ?

What happens if a function in base class is overridden in derived class ? Does it replace it with the new function or copies it in other location in derived class memory ?
