Find position of first occurrence of a substring in a string

Question

I wan\'t a method with which to find a string within another string. It should return the position of the first occurrence of the substring. (In VB 2008 !)

Answer 1

position = instr([stringField] & " ", " ")

Looking for the first blank in what might be an empty string named [stringField]. The ' & " "' avoids an error situation where there are no blanks in [stringField].
