I am using VB 2010 & going to prepare a billing software for my small company. I need complete code to make the total price of a particular product after entering data in all text box field and final price will show. Also all text box excluding "basic price" will show default value. as "zero". When I select from database (stored in WindowsApplication1 as Pricelist.accdb) the "item description", same time the "basic price" and "unit" automatically shows in there field. But I am unable to addition / subtraction with other text box field.
Please help me.
