If you mean in a VFP app, it should be pretty easy. Spin through the string, looking at each character. Keep a running count of how many are ISDIGIT(), ISUPPER() and ISLOWER(). You have a strong password if:
( LEN() >= 6 ) AND( DigitCount >= 1 ) AND ( NonDigitCount >= 2 ) AND ( UpperCount >= 1 ) AND ( LowerCount >= 1 )
