Monitoring for changes?

[Mr60s]

Hi there!

I just signed up here and was hopeing for some help.

I was wondering if its possible to monitor lets say a variable for changes.

If i got this variable or whatever:
Dim Test as integer = 1

When Test changes to let's say 2, I want to execute some peace of code.

How could I manage to do this?

It is not. You can write a property and manage monitoring in the setter:

Public Event NewPropertyChanged As EventHandler

Private newPropertyValue As Integer
Public Property NewProperty() As Integer
    Get
        Return newPropertyValue
    End Get
    Set(ByVal value As Integer)
        newPropertyValue = value
        RaiseEvent NewPropertyChanged(Me, New EventArgs)
    End Set
End Property
