Question

I’m creating a program in which I have a publicly defined boolean value

Public boolOverallStatus As Boolean = True

and I need to execute some code whenever the boolean value changes. In previous applications, an actual form item change handled this, but it can be changed by several different subs.

How would I handle this? I’m looking through msdn, but it’s rather confusing.
In a nutshell: How to execute code when the event of a boolean value changing occurs.

Make it a property instead.

Private _boolOverallStatus As Boolean = True

Property boolOverallStatus As Boolean
  Get
    Return _boolOverallStatus
  End Get
  Set(ByVal value as Boolean)
    If value <> _boolOverallStatus Then
      _boolOverallStatus = value
      '// handle more code changes here.'
    End If
  End Set
End Property
