Hi, im looking for some advice/guidance with regard to visual basic. Im and final year engineering student and my project requires me to make a graphical user inter phase to teach aerodynamics. I need to find out how to link the programme i design through VB with excel. Then the user can input their own data into the programme and excel will use this to make a graph and input the graph into the programme. Kind of like working in the background and producing the graph in the user inter phase. Sorry for the prolonged explanation but i've very limited computer and visual basic knowledge so its quiet confusing for me to explain. Could u tell me if this is possible and where i could find the information to teach me how to do this? Thank you, your help would be very much appreciated. Is the question above you already answered the same thing? it sounds similar but i dont understand the computer language! Sorry
