Implementing elegant if else

A typical if else condition in VBScript would look like below

View Code QTP
If (message = "ok") Then 
    Msgbox "I am calling ok"
Else
    Msgbox "I am calling not ok"
End if

VB provides a elegant function named IIf for such small if else conditions. The function can be easily witten in VBScript

View Code QTP
Public Function IIf(ByVal pCondition, ByVal trueValue, ByVal falseValue)
    If pCondition Then
        IIf = trueValue
    Else
        IIf = falseValue
    End If
End Function

Now the same code be written in single line of code

View Code QTP
Msgbox "I am calling " & IIf(message="ok","ok", "not ok")
