A couple of problems with the code you show: 1. You instantiate FMyList as a TStringList in your TInhertProducts constructor but never free it. 2. Calling mlist.MyList:= memo1.Lines, as you show, will clobber the internal reference to your internally constructed FMyList that you previously created; replacing it with a refrence to the TMemoStrings instance maintained by the TMemo. Doing this makes it actually impossible to free the original TStringList (you no longer have a reference to it) and will cause problems if you later free it, as it now actually refers to the internal TStrings instance of another class. If you were just meaning to COPY the values from one to the other you want to use the overridden TStrings.Assign() method. Beyond those issues, the class otherwise appears okay. I'm having trouble recreating an access error given what you've shown Can you provide some context code showing where and how you're instantiating Mlist and actually accessing the methods?
