I am a new student in the area with very little programming experience. We are working with arrays in our vb.Net class and I am coompletely lost. Our program has to look up part numbers in order to improve customer service. The user has to enter the part number and brand and look up the corresponding Auto number. They get to choose from 3 brands which can be selected by radio button. We can either store the part numbers in a 2-dimensional array or in an array of a structure. We have to use the part number to lookuup and display the part number. can anyone provide any assistance as to where i should start?
