Detect Null Or Zero-Length Fields In A Database

This syntax is much faster than using an If.Then.Else construct to detect null or zero-length fields, and it will ensure that an error will not occur. For strings:
 Dim sVar As String
.
sVar = "" & ds!sField
For numbers:
 Dim nVar As Integer
.
nVar = 0 & ds!nField
This assumes that ds is a dynaset and sField and nField are two fields in that dynaset.
