The first thing I see in which-func.el is that you'll need to add
visual-basic-mode to which-func-modes, and perhaps to
which-func-non-auto-modes.

If visual-basic-mode support imenu, then you should be good to go.
And if beginning-of-defun works in that mode, that might be good
enough.

Otherwise, you could try defining a function that returns the name
of the current function in visual-basic-mode, then assign that to
which-func-functions (actually, use add-hook with non-nil LOCAL arg).
