[development-axapta] Re: Closing files after usage

[wgr22091962]

hi preston (and others),

it's a side-effect of the compiler-advancement in Axapta 3.0!

the finalize() method of system class "Io" and all derivated classes 
is declared as an protected method (also in Axapta 2.5).

since Axapta 3.0 the compiler now consider the "scope" of an method, 
which will be defined in the method-header by using the so called 
method-modifier:
- private
- public
- protected
- final
- abstract

so, when compiling object-code like

    Io io = new Io("myFile", "W");
    ;
    io.finalize();
Axapta 2.5 will not send a compiler-error, but Axapta 3.0 will!

regards
wolfgang

Maarten & Wolfgang, 
 Thanks for the heads up on finalize being protected in 3.0, I 
hadn't
realized that. It would have slapped me in the face when the time 
comes
to upgrade one client where I reuse the same IO object for multiple
files in a single method.  Does anyone know if this was an 
intentional
feature or just a side affect of some other change?

In 3.0 this method cannot be used because the method is protected. 
if
you 
declare your asciiio object as an object, you are able to use the
finalize 
method.
ex.
object export = new asciiio(filename,'W');
