Question : If Statement on Control Source

I have a textbox on my form called: "txtPPAExpiryDate" and it is bound to a date field called "datPPAExpiryDate".  

If the field is empty/null I want the textbox (and it's label to be invisible) and a different label to display called "lblWillNotExpire".

Does this have to be done in VBA (if so on what event and what's the syntax) or can it be done on the Control Source field, in the property window (if so what is the syntax)?

Answer : If Statement on Control Source

Cannot go beyond 256 gb on a datastore which was created using the block size 1. See the following link for clarification.

There is no way you can increase the block size without destroying the datastore. Just move all the files to another datastore using svMotion and reconfigure the datastore with what ever block size u feel is appropriate for furture use.
