It is far faster to compare the length of a string to 0 than it is to compare the string itself to empty string. Further, the LenB
implementation is faster than the Len implementation, and is therefore preferred.
Noncompliant code example
If Text = "" Then
If Text <> "" Then
Compliant solution
If LenB(Text) = 0 Then
If LenB(Text) <> 0 Then
