Hi All,
I currently have a spreadsheet, that takes input as 4 characters and 6 digits and outputs a further 1 digit as a checkdigit. This is used to ensure the entered data has the correct check digit.
I would like to convert this into a program - hopefully a small exe, that other people can use. Maybe in the future develop it as a web service / widget type program also.
Has anyone had any experiance of writing a small program like this for windows? Any pointers where to start would be great! Maybe I can use what I have already in Excel as a basis?
