For example add two vectors I can't see debugging details such as block idx,warp index

Answer 1

The problem is that you have made a breakpoint in the host code but you have no breakpoint in the device code.
When debugging with the regular VS debugger, the debugger will hit breakpoints in the host code but not in the device code.
