I'm new in programming forms in Access ( via VB or wizards).
On a form I have created a textfield A and a date field B.
I have another field C. C is empty when opening the form and should have the value of the contatenation of A+B on exit of field B. ( C is gonna be used as unique key).
How do I do that. I tried with C Default Value = [A]+[B].
Somebody ideas. Also can you please recommand we some tutorials on programming in Access (VB and wizards) who are on the web?
