VB beginner needs help: I am trying to calcualte an invoice total and generate an invoice number for each invoice processed. my items info are loaded from a text file into list boxes. I am getting my items’ price from a listbox name lstSalesPrice. Ineed the lblTotal to display one final total of all the prices listed in that listbox If I delete an item from the listbox, the lblTotal should show the reduction in the total. Can you please help. It is an emergency. This question has already been posted but I need to have answer as soon as possible.
