IsNull ..... or not
Access Howto:
I allways had problems with the IsNull function as it will return False if it is empty so one would have to check for IsEmpty etc. all this checking became borring, so I use this little function:
Function IsBlank(V As Variant) As Boolean
On Error Resume Next
V = "" & V
If Len(V) = 0 Then IsBlank = True
End Function
Works every time.
Function IsBlank(V As Variant) As Boolean
On Error Resume Next
V = "" & V
If Len(V) = 0 Then IsBlank = True
End Function
Works every time.
