Reply: VB functions no OCX maybe What do you mean by "measure". Are you doing an oscilloscope? or do you want numeric? I don't think VB is fast enough to do the raw processing for a real time display. For high reoluion a DSP would be nice. There are quite a few programs out in the web that do the oscilloscope type display using the sound card for input. There are add-in cards and external devices for wide range data acquisition.
