Are there any good resources about using c++ and assembly, preferably using vs.net or vs6?

You generally wouldn''t want to use much inline assembly in your programs.

If you''re writing your own hand optimized functions, you would use "__declspec( naked )" and such VC functionality to get full control over code generation.

Taken that you have previous experience with assembly programming, MSDN should be sufficient for your compiler specific documentation. For the actual assembly, the Intel (and AMD) reference manuals are quite good.
