[dba-VB] Count of specific character

Is there any single function that will return a count of a specific
character in a string?

I have a situation where (apparently) the header of a CSV file has the same
field name twice.  I am trying to determine what is going on, so I want to
count the field separator characters in the header and the first line of
real data to see if there are more fields in the header than in the data or
if something else is going on.
