Dear GME users and developers!

There's some need to change an important behavior related to creation of
GMEOLEApp. As you know you can create the GME OLE object by creating a
GMEOLEApp. The interesting thing is what should happen when you already
have a GME running and you issue the creation of a GMEOLEApp. In this
case the program returned the already running GME's OLE object instance.

We've got some request that it would be better if another GME started up
in response to a second (or more) GMEOLEApp creation request. But this
would break such codes which rely on the old functionality and assume
that they will get the already existing running instance.

Please notify us by replying to this email if such a change would break
you current code. Our goal with this letter is to see if there's anybody
out there who rely on this. If there won't be complaints for some time
we would change the default behavior to the way I described.

Thanks,
Csaba Toth
GME developer

Subject: [gme-users] Getting the IGMEOLEApp interface from GME.Application
	COM object
Message-ID: <276F2D75-982F-4269-8C9C-FAA11C70AEF4@dre.vanderbilt.edu>

Hi,

I am trying to do some automation work with GME, but I am running into  
some minor problems. More specifically, I am trying to create an  
instance of the GME application without opening a project (i.e.,  
instantiate GME using the GME.Application ProgID). Right now, here is  
the code that I thought would do that:

  CComBSTR progid ("GME.Application");
  CComPtr <IGMEOLEApp> gme_app;
  HRESULT hr = gme_app.CoCreateInstance (progid);

I, however, keep getting an invalid interface cast/query error. I  
thought the above would work because in PERL I have the following code:

  sub get_gme ()
  {
    # Create an instance of GME.
    my ($gme) = Win32::OLE->new ('GME.Application', 'Exit')
      or die 'GME is not installed\n';

    return $gme;
  }

The object returned from the code above implements the IGMEOLEApp  
interface as expected because code like the following works:

    print get_gme ()->Version ();

So, does anyone know what interface I should query when I instantiate  
a GME.Application COM object, or how to get the IGMEOLEApp interface  
from the GME.Application COM object??

Thanks,

James
