[Gambas-user] R: How to know is my Form activated or not?

[Fabien Bodard]

Public Toto as String 'is public
Public  _Toto as string 'Is public but hidden
Private $sToto as String 'Is Private

Property _Toto as String 'Is public access but hidden

Dim sToto as string 'Is Local

In Fact it is the convention used on the gambas IDE and generally on
my own projects.

Even _MyClass is hidden by the ide

Well generally the _Var means to not expert DO NOT TOUCH THAT WITHOUT
MANY CARE !
