DLL versus OCX

Hi,


Does anybody know the exact difference between a DLL and an OCX file?
I understand that they are both dynamic library files or am i wrong?

Is it possible to write an OCX file an include this in an VB.NET application?

At my internship i'm supposed to write a library in C++ that can be included into a Visual Basic application.

Software is Visual Studio 2005 Professional

One question is not about programming, the other is not about C++. Wrong forum.
