in reply to 'emptyenum' error w/ use Win32::OLE::Const 'Microsoft Word'

There is another way to get to the Word-constants, which in my experience is more stable, when there are many constants, as there indeed are in Word.

I would like to encourage you to try this instead to see if it helps:
use Win32::Shortcut; use Win32::OLE qw(in with); use Win32::OLE::Const; ##=>Changed my $wdc = Win32::OLE::Const->Load("Microsoft Word"); ##=>Added my $x = Win32::OLE->GetActiveObject('Word.Application'); # snip $x->Selection->Delete( { Unit=> $wdc->{wdCharacter}, ##=>Changed Count=>1 } );

Searching through some old email conversations with jand, the author/maintainer of Win32::OLE, from 2002 I found this.

Nothing new under the sun, it seems. But the indicated way works.

Notice that your erroneous linenumber is -1 whereas mine is 65535, 16 bit integers or what?

    Success! Thank you. No more emptyenum complaints (at least after initial testing. :-)

    I applied your suggestion to all such wd occurrences:

    # instead of: # $x->Selection->Collapse( { Direction=>wdCollapseEnd } ); # do: $x->Selection->Collapse( { Direction=>$wdc->{wdCollapseEnd} } );

    As this example also shows, I left other Word-particular terms (such as Selection, Collapse, Direction) alone.

    P.S. Yes, I wondered why mine had -1 when others had 65535, but that was a weirdness to leave for another time.
