Release object in a procedure

TheMSsForum.com: The Microsoft Software Forum

Hi.
I have a simple problem
Here's my procedure :

PROCEDURE DestroyMyObject
PARAMETERS TheObject
RELEASE TheObject
ENDPROC

I tried to call it with @ but it has no effect.
How can I release my parameters in a procedure ? Is it
possible ?
Thanks in advance for your help.

The way you try it, it's not posible because you get a reference or value in
a new variable.
With the RELEASE you release that new variable and not the original.

The variable your release must be in scope, so make it a private (or public)
var.

*Code:
ox = CREATEOBJECT("demo")

DEFINE CLASS demo AS Session

PROCEDURE Init

private poObject
poObject = CREATEOBJECT("label")

this.destroymy()

*- this fails now...
WAIT WINDOW poObject.caption

ENDPROC

PROCEDURE destroymy()

RELEASE poObject

ENDPROC

ENDDEFINE
* End

hth,

Ok.
This is not exactly what I wanted but it helped me to find
a solution.
Thank you.

I ask myself, why someone should do that ?

If you want to delete an object, that exists in a containership, you can use
the REMOVEOBJECT() method of that container. Each container class provides
that method.

If you want to delete an object, whose reference is in a variable, just set
the variable to .null. !
