RE: Win32::OLE-GetActiveObject not working!
Are you running XP SP2 or recently upgraded? Yes to SP2, but not recent. Recent hot fixes.. auto applied by windows update. Recently trying to use Win32::OLE though, so no help in finding out if this is something new.. but others seem to have similar problems. This returns the value zero: use strict; use Win32::OLE; my $Count = Win32::OLE-EnumAllObjects; You may need to setup your DCOM permissions. Checked that first, but what DCOM permissions, and how do I setup these permissions so that perl.exe has sufficient rights when being run as me? The default permissions are in place, and seem fairly permissive as reported in dcomcnfg. In any case, I believe that the Computer defaults specify that launch permission and activate permission go hand in hand.. no? Since I can launch the application, why wouldn't I be able to activate the application? And.. I am member of Administrator group. Your ID may not have rights to access the COM objects on your local PC. I can use Internet Explorer and the Win32::OLE - Type Library Browser to enumerate objects in Internet Explorer. I can use the Microsoft OLEView application to enumerate and view objects. I can use mmc viewer to adjust security settings of My Computer and individual DCOM items at an administrative level. Under the Component Services mmc you can manage the permissions for your PC My computer, or you can manage individual objects. Yup. Just in case, I added my specific username to the default permissions at the Computer level with access to both local and remote rights in all contexts. What is very odd is that Win32::OLE is unable to enumerate objects, but it *is* allowed to launch them using the same interface. Start-run-dcomcnfg (This will get you into the MMC.) uh huh.. I'm still not certain that this behavior isn't just restricted to my machine and a few other users. Is there a maintainer of the Win32::OLE core who can set the record straight here?

I could be wrong, but I don't think iTunes is an OLE Object which could
be causing your troubles.
It's a shame that it doesn't have a direct Perl API.

Subject: Win32::OLE-GetActiveObject not working!
Here is a snippit based on the example in the ActivePerl User Guide with
iTunes instead of Excel..
# use existing instance if iTunes is already running
eval {$iTunesHandle =
Win32::OLE-GetActiveObject('iTunes.Application')};
die iTunes not installed if $@;
unless (defined $iTunesHandle) {
$iTunesHandle = Win32::OLE-new('iTunes.Application', sub
{$_[0]-Quit;})
or die Oops, cannot start iTunes;
}
A running instance of iTunes will always be killed, because
Win32::OLE-GetActiveObject never finds an object! I tried a generic
CLSID, and specific PROGID version strings, but nothing makes
GetACtiveObject return an object. I used OLEView to check on the CLSID
of iTunes.. you can see it is just a fairly straightforward interface.
I think this is a problem with RPC, SP2 and new security patches. I had
some other trouble with RPC recently for an install program for a USB
DSL modem.. it died at the end with an RPC call failed message. No one
seemed to know what I was talking about (happened 2 days ago), but I'm
certain my computer is ok. I was going to use Safe Mode boot to play
with the permissions, but I can't afford the time to reinstall windows
if something goes wrong.
Any other applications that can't use GetActiveObject through a typelib
interface? Is there a work around for this? Is it just my problem?
