Re: remotemachine accessing: did not get any values when I use Win32::NetResource

in reply to remotemachine accessing: did not get any values when I use Win32::NetResource

You're declaring $resources in the call to GetSharedResources. The documentation states the syntax for calling that sub is GetSharedResources( \@Resources, dwType, \%NetResource = NULL ) (note the array ref as the first argument). The tests I ran gave different results based on how the variable was declared and initialized.

use strict; use warnings; use Data::Dumper; testsub( my $ref1, 'hi' ); print Dumper( $ref1 ); # output: $VAR1 = undef; my $ref2; testsub( $ref2, 'hello' ); print Dumper( $ref2 ); # output: $VAR1 = undef; my $ref3 = []; testsub( $ref3, 'howdy' ); print Dumper( $ref3 ); # output: $VAR1 = [ 'howdy' ]; sub testsub { my ( $ref, @args ) = @_; push( @$ref, @args ); }

Try declaring $resources before the sub call, and assign an array ref to it rather than leaving it undef. I hope another monk can help to explain this behavior, because I'm not sure I understand it.

    I thought it might be that at first, but it gets auto-vivified. The problem is the invalid resource name.
