cst (VBA) problem

Hi everyone,
Im trying to use VBA in CSt Microwave Studio to define a goal that the radiation to be as sphere, or by other words min directivity to be close as possible as max directivity.
plz i need help because i haven't used this before.

thnx

I could find the max directivity and i tried to use the same function for minimum but it didnt work. Also i want to calculate the average. the code is shown below. please can you help me with this

//
userdefined goal function for optimizer

Option Explicit

Function GoalFunction() As Double

Dim cst_value As Double

With FarfieldPlot

.Reset

SelectTreeItem "Farfields\farfield (f=0.433) [1]"

.SetPlotMode "directivity"

.SetScaleLinear True

.Plottype "3D"

.Vary "theta"

.Thetastep 1

.Phi 0

.Plot

Wait 0.02

' Maxmize directivity

GoalFunction = 10/Abs(.Getmax)

End With

End Function

Sub Main()

MsgBox CStr(GoalFunction())
End Sub
//

in the help you have some programm talking about gain and directivity in VBA. in the help write "userdefined watch" and "Visual basic (VBA) langage".

I'm studying VBA right now and I try to do something else, I have a macro which exist already. I can make this macro local or global. I want to run this macro after each calaculation of a parameter in a parameter sweep simulation. I know I have to write something in the case 1. I tried to write open "namemacro.mcr" but it didn't work. I f someone has a help, I will be grateful:

-------------------------------------------------------------------------
' userdefined watch for parameter sweep

Option Explicit

Sub ParameterSweepWatch(action As Integer)

'Please define actions for the parameter sweep watch here.

Select Case action
Case 0
'Please define actions before the parametersweep starts.

Case 1
'Please define actions after each calculation.

Case 2
'Please define actions after the parametersweep has finished.

End Select

End Sub

Sub Main()

ParameterSweepWatch 0
ParameterSweepWatch 1
ParameterSweepWatch 2

End Sub
