I am looking for a simple (read very simple) vc++ example for acquiring data from an analog channel on a PCI 6221

Hello twrfte,

Welcome to the NI forums.  The examples should be installed in C:\Program Files\National Instruments\NI-DAQ\Examples\VisualC\Ai.  If they are not here, then you need to be sure that you included support for VisualC when you installed the driver. Below is some links to some resources to help you get started with basic DAQ programming. I hope this is what you are looking for
