List shared Folders on network

[THEROB]

How do you list all shared folders on a particular network pc.

Thanks

After quite an extensive search no one seems to know how to do it.

The only way I can think of is to use perl script to list all of the folders - then use vb to parse the output. I used this perl script:

use strict;

my $res;

$res = `net view`;

my @computers;

@computers = split(/\\/, $res);

foreach (@computers)
{
	$_ =~ /([^ ]*) /;
	my $pc = $1;

	$res = `net view \\\\$pc`;
	print $res;

}

Anyone got a better way?

If I understand you correctly you want to list shared folders simular to how they are listed in the Network Neighborhood, is that correct?

To do so you would use WNetOpenEnum to start the enumeration of network resources and then keep calling WNetEnumResources until it returns ERROR_NO_MORE_ITEMS. I could write a demo for you if you can't figure it out from this information but I don't have time at the moment so that have to wait a few hours.
