S The bar code APIs, defined in the IADC interface, are available to get
bar code data from the bar code scanner. The following example shows
how to programmatically collects bar code data:
// Linked with ITCUUID.LIB
// Linked with ITCAdcDevMgmt.lib
// Name of the ADC device.
// COM interface to return
// Device's Flags
// the returned interface
// Buffer to put the ADC data.
// Size of pDataBuffer in bytes.
// Number bytes returned.
// Time stamp of the received data. NULL.
// Number of milliseconds to wait.
