Maarten,

Do you mean for any variable? No, you can not. If the instance of the
type of the variable exposes events, then you can attach to those, but in
general, no, you can not be notified when an arbitrary variable changes.

Hope this helps.

thanks,

yes i mean for all variables

for examle
string test = "test" ;

and then fix an eventhandler that starts if the content of the variable
changes.

You could create a custom object and add event - handling to it. For an
example, see Darth Pedro's "ArrayList with Events" at godotnet.com:
