OLEUninitialize()

OLEUninitialize()

Postby Enrico Maria Giordano » Wed Dec 07, 2011 11:24 pm

Is the function OLEUninitialize() obsolete (ie. not required anymore)? I found it inside tcomobj.prg and testole.prg.

Enrico,

OLEUninitialize() is required when using OLE:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms691326(v=vs.85).aspx

but as we are using Harbour OLE support, Harbour automatically calls it, so we don't need to provide it
regards, saludos

So, it must be removed from tcomobj.prg and testole.prg?

Enrico,

Yes, I think that we could remove it though lets see if we can check it to be 100% sure about it.

Another choice is to include that function in those examples.

Ok, keep me updated.

Ok, but the question is: is it required? If it is not why we need to include it in the samples?

Enrico,

Harbour can implement atomatic "cleaning" when a variable is "destroyed", thats why some calls are no longer needed.

In example:
Code: Select all  Expand view
  METHOD Destroy()

   DESTRUCTOR Destroy()


That above means that if an object is made equal to nil, or simply exiting from a function or procedure where it is created, then such method is invoked and there we can do the cleaning. What I am not sure about is if xharbour implements it too. I think so.
regards, saludos

Dear Antonio, suddenly I realize that I didn't say that the following sample doesn't compile because OLEUninitialize() doesn't exist:

Code: Select all  Expand view
#include "Fivewin.ch"


FUNCTION MAIN()

    OLEUNINITIALIZE()

    RETURN NIL
