Thansk for u replying.....
i had tried to double up the single quote. but still getting the error.
i know in SQL we need to double up the single quote in order to retrieve/get record from database.
my problem now is, i try to direct pass the string (contain single quote) into the crystal report by using formulas without save the string into database and then retrieve it.
i had do the online research but din find any soluction yet.
the alternatively way that ur suggested may be i will consider it. but i have to restrict the user entering the character so that they canot enter this character ^
beside this, is there any soluction/suggestion to solve my problem?
