Why is the fourth line different, and where is it documented that it
should be different?

The best part about procrastination is that you are never bored,
because you have all kinds of things that you should be doing.

'' can be interpreted as the bitwise and operator, and in your 4th line
it is. The file handle $fh is being bitwise anded with the result of the
function call to hexdump(). Either omit the (you don't need it
anyway), or put parenthesis around the function call to disambiguate:
print $fh ( hexdump ());

Either drop the or add a + :
print FILEHANDLE LIST
print LIST
print Prints a string or a list of strings. Returns true if successful.
FILEHANDLE may be a scalar variable name, in which case the variable
contains the name of or a reference to the filehandle, thus
introducing one level of indirection. (NOTE: If FILEHANDLE is a
variable and the next token is a term, it may be misinterpreted as
an operator unless you interpose a + or put parentheses around the
arguments.)

Bonus round:
In addition to what I said in my previous post, a '+' can be used
sometimes to disambiguate certain types of expressions. In this case,
the results can vary depending on the placement of a single space:
print $fh + hexdump (); # ok
print $fh + hexdump (); # error
print $fh +hexdump (); # ok
print $fh + hexdump (); # error
Why?

GUI - Browse for directories.
Hi all, A while back a discussion issued about browsing for files (multiple selection). I need a slight variation on the subject: I want to use the getOpenFile method of Tk (or the GetOpenFileName of Win32::GUI) to open a DIRECTORY: I want to enable the selection of a directory in my directory tree structure and return that string to my script. How can that be done? I was able to find a cpp implementation of OpenDirDlg class that enables that, but I'm looking for a Perl solution (to embed in my script). Any help/ideas would be greatly appreciated.

Re: [Attn: McCarty, Michael F] Re: Out of Office AutoReply: file handle strangeness
So what doesn't the list manager simply make Out of Office a forbidden sequence in a subject or body, and trash such emails? That would cut the autoreplies at least by 2/3rds. I could certainly live with that restriction and it seems you can't teach people how to do it right, just like you can't teach people not to install viruses on their computer, when the instructions are so clear and self-contained.

On approximately 7/18/2004 10:26 AM, came the following characters from the keyboard of Tobias Hoellrich: In my case, every single OOO message via the win32-users list (actually any non-work list) ends up in Spampal's (www.spampal.org) black-list, which means I'm never, ever going to see a message from that user (that email-address) again. This also locks out legit messages from those users, but that's a problem I can live with (and there's still the question whether I actually want to see a legit message from a user who is inconsiderate enough to send his OOO message to a list). I hope that is your choice, not a requirement of using SpamPal. The latter would seem quite onerous, and would not be appropriate for every situation. -- Glenn -- http://nevcal.com/ === The best part about procrastination is that you are never bored, because you have all kinds of things that you should be doing. ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
