Simple...

If xxx() Then
    If yyy()
        'Only if xxx() and yyy() are true
    End If
End If

Ok, let's try the proper syntax...

If xxx() Then
    If yyy() Then
        'Only if xxx() and yyy() are true
    End If
End If

AndAlso and OrElse are new keywords in VB.Net that short circuit compound conditionals if a preceding expression evaluates to false.  These can be combined to more than 2 expressions as:

If xxx() AndAlso yyy() AndAlso zzz() Then

End If

In this case the only way zzz get evaluated is if xxx and yyy are both true.
