posted 13 years ago
l am doing my project in J2ME and having some problems of writing some program as below: 1) Delete records with specifing record IDs in a text field l have done the adding records into a record store part.But l have a problem of writing codes to delete records from the record store by keying in record IDs in a text field. 2) subtraction operation l add records with prices(eg:$20.00,$30.00) and set my amount expenses of a month(eg:$100.00) in the text fields. then, l click a view form to check my balances in the form. (balance= expenses - prices).It is applied to everytime l add a new record with pricing. is there anyone could help and guide me? or give me some source codes or related codes for above program.Because l really have no ideas on how to writing the programs and need them urgently. thank you very much.
