Full Discussion: Perl error: Can't call method "value" on an undefined value
Homework and Emergencies Emergency UNIX and Linux Support Perl error: Can't call method "value" on an undefined value Post 302675105 by otheus on Saturday 21st of July 2012 05:00:58 PM

Code:
            my $fcell = $worksheet->get_cell($row, 11);
            my $name = $fcell->value();

What's probably happened is that get_cell() returned an undefined object (perhaps because that cell was undefined or empty), and thus, $fcell->value() doesn't have any meaning. Test $fcell before trying to use it:
Code:
            next unless $fcell;

As to your 2nd question:

also to add. I have removed my personal info in the email section but that does not seem to work as well when i input the data. we have some older scripts where we do not specify the smtp host and the ip we only specify the email address. is this at all possible in this script to?
That depends on your email set up. On most UNIX systems you can send the mail via sendmail directly, but it's not portable to, say, windows systems:
Code:
open(SMTP,"|/usr/lib/sendmail -t");
print SMTP "From: $sender\n";
print SMTP "To: $recipient\n";
print SMTP "Subject: $subject\n";
print SMTP "\n";
print SMTP join("\n",@log);
print SMTP "\n";
close SMTP;

XmScrollVisible(library call)											     XmScrollVisible(library call)

NAME

       XmScrollVisible -- A ScrolledWindow function that makes an invisible
	descendant of a ScrolledWindow work area visible

SYNOPSIS

       #include <Xm/ScrolledW.h>
       void XmScrollVisible(
       Widget scrollw_widget,
       Widget widget,
       Dimension left_right_margin,
       Dimension top_bottom_margin);

DESCRIPTION

       XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function re-
       positions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location relative
       to  the	viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the
       ScrolledWindow widget be set to XmAUTOMATIC.

       scrollw_widget
		 Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant.

       widget	 Specifies the ID of the widget to be made visible.

       left_right_margin
		 Specifies the margin to establish between the left or right edge of the widget and the associated edge  of  the  viewport.   This
		 margin is established only if the widget must be moved horizontally to make it visible.

       top_bottom_margin
		 Specifies  the  margin  to  establish between the top or bottom edge of the widget and the associated edge of the viewport.  This
		 margin is established only if the widget must be moved vertically to make it visible.

       For a complete definition of ScrolledWindow and its associated resources, see XmScrolledWindow(3)
