How to Use Triple State Check Boxes in Access


 S  M  L  XL  FS  |  Slo  Reg  Fast  2x  |  Bookmark Join Now

In this Microsoft Access tutorial, I will show you how use a triple-state checkbox to save a null value to indicate "I don't know" the answer to a yes/no question.

Stanley from Wilmington, Delaware (a Platinum Member) asks: I have a few yes/no fields in my school database for things like IsParent, IsFaculty, IsStudent, and so on. However, sometimes when we enter the data, we don't know some of these things. For example someone could be a faculty member but we don't know if they're enrolled in classes too (it happens). However with a yes/no field, the database indicates that they're not a student when they are. How do I handle this?
