>I create cursor in my program , add a record and bind it to my grid. it is fine. Grid show my inserted record. However, when I try to SELECT mycursor after INSERT a record from other method, VFP return "alias is not found". Any ideas?

Do you have alias names in your indexes or something like that? If you have mytable.myfield as an index expression, and your table is open with the alias "mytable", you might get that, change the expression to just "myfield". Or do you have a relationship or filter set with an invalid alias? I think somethign of that sort is the problem here.
