Need help with a multi-entry input box

Could someone please provide an example of how to use a single Visual Basic input box with multiple input entries?

I need to input a prefix number and an item number that will be stored in an access database. I would like to use one input box to be able to enter both sets of data, but am unsure of how to do this.

Any help would be appreciated.

Nup.

Do it either by just having a single number, that you chop into its seperate parts, or have 2 textboxes...when you enter the prefix, say 3 numbers have it jump automatically to the second box so the user can keep typing the item number.

Or use a format like nnn-nnnnnn and then your code can split the two parts on the "-"
