I would really like to continue learning C++

I have recently been giving C# a try but would now like to continue with C++.
I also believe that i have a pretty good understanding of C#.

I have done all of the console application stuff. If statements, file IO, etc
(Meaning i know the C++ syntax).

And i am wondering what to do next? I would guess to start with a C++ UI application but i don't know where to begin but i do not want to use .Net(100% native code).

-Where do i begin? I have visual studio 2008 pro installed.

Thanks.
