Ok, I finally found it. it has to be replaced by a double quate as follow "The word ""hello"" is quoted." so in C# it will be: "The word \"\"hello\"\" is quoted." thanks anyway!

C# code -------

int intCopies = 1;
string strAddress = "6534 Burbank, next to the \"Amy Books\" bookstore";
string temp = orpt.DataDefinition.FormulaFields["Address1"].Text;
orpt.DataDefinition.FormulaFields["Address1"].Text = temp.Replace("Address1", strAddress1);
orpt.Refresh();
orpt.PrintToPrinter(intCopies, true, 1, 1);

------------------------- Crystal Reports --------------- in crystal reports I have a formula named: @Address formula text: "Address" -------------------------- I'm using VS 2005 with Crystal reports version 8.5 Thanks!
