    How do you use VB and the computer's microphone to
    to a pitch and determine its frequency in hertz?

    Well, first you have to get the address of the sound card, then the address of the mic, and probably another address. I have been able to do this only with a Sound Blaster 16 card, so I don't know about other cards, but once you can sample the input continuously, you can add some code that would tell how many times per second that it got up to a certain value relative to the center of the wave. The hardest part, though, will be sampling the sound card.
