Hello.

I've created two classes, Class1 and Class2, taking as base FormSet
class.

A form in Class1 must call another form in Class2 pressing a button.
in the clic method of that button i have something like this:
Class2.form1.show

My ploblem is: the Class2.form1 is shown on the scrren, but when the
clic button method ends, the Class2.form1 is release...

Can you help me??

Maybe I misunderstood your description - is "class2" a public
reference or is it a variable created in the current method or
procedure?
If the latter, it might be released, "go out of scope", when your
method is over (as Vfp variables do by default as long as they
are not declared as Public).
Perhaps you can use a property of the current (parent) form
instead of a Local or Private variable.

Hi Stefan.

Initially, class2 is an empty public variable wich in the button's
click method is an object assigned to it:

class2 = CREATEOBJECT("CLASS2")

I don't believe that the error is caused by the scope of the variable,
because is declared as PUBLIC, not as procedure variable or local
variable.

Hi Francisco

Hmm, this sounds exactly like a out-of-scope issue ...

.... but you're right, this sounds as if it where not.
Can you post the code of your commandbutton.Click()
method? Or even a complete runnable demo code PRG?

Can you still see "class2" in the debugger's Watch window
when your Click() method is over?
Do you Release class2 somewhere in your code between the
Public statement and before the CreateObject / Show ?
Does the behaviour change when you use a property of the
persisting parent form object instead?
*!* class2 = CREATEOBJECT("CLASS2")
If Not PemStatus(Thisform, "Class2", 5)
Thisform.AddProperty("Class2")
Endif
Thisform.class2 = CREATEOBJECT("CLASS2")
...

whit this line the problem was resolved:
you were right... i referenced the class2 variable by its name, not as
property of class1.

Thank you very much for your time and your help.
