Czarina,

While there is not exact macro-substitution you can do shell commandline executions.

Imports System
Imports System.IO
Imports Microsoft.VisualBasic

dim oshell as New Shell.DisplayCommand()
vbshell.SomekindofAction



Or

You have use AddressOf which will come the closes to marco-substitution of FoxPro.

AddHandler objValid.ValidationEventHandler, AddressOf ValidationHandler

Public Sub ValidationHandler(ByVal sender As Object, ByVal ByValargs As ValidationEventArgs)
--do something

end sub

Hope this helps
