I need to get data from a text or excel file and input it into a windows program that I do not have source code for and cannot get it.

What I am trying to do is get sales order data from one of our customers in a file and then read the file and input the order information into our sales order system by actually stepping through the order entry process so all the checks for item #'s, zip codes, etc that are already in the sales order entry software are utilized, basically so that data files integrity is maintained.

I am very green when it comes to programming, can anyone tell me if this can be done using vb.net or should I look into using another programming language.

Thxs, Neil.
