Stephen,

There's some holes in your description. The users will enter something like cStart = "ABCDEFG", cEnd = "ABDFZZ" and you want to generate all the values in between and come up with what? Are you generating Keys for records (like lottery tickets) and the user will then enter one to access the rest of the record?

What is the purpose of the combo box with all possible combinations?
