Further experimentation indicates that Win32::OLE works differently and does not set $@, nor does the eval make any difference. But error messages can be obtained by using
$errmsg = Win32::OLE->LastError;
This can be searched for the needed string and then ignored. The message still comes out on the screen for the Perl script window but I found that can be turned off by setting the Warn level to 1 instead of 2. So a code snippet that seems to do the job is:
$warnlevel = $Win32::OLE::Warn; $Win32::OLE::Warn=1; $done = 0; while ($done == 0) { if ($excel->ActiveWorkbook) { sleep 15; } else { $errmsg = Win32::OLE->LastError; if ($errmsg =~ m/busy/) { sleep 15; } else { $done = 1; } } } $Win32::OLE::Warn=$warnlevel;
