IsEmpty
The IsEmpty function determines if a variable holds
the empty value. An Empty value only exists for a new
variable that has been declared but not defined yet.
Dim sVar
If IsEmpty(sVar) Then Response.Write "It is Empty"
sVar = "Something"
If IsEmpty(sVar) Then Response.Write "It is Still Empty"
