in reply to Access given folder to parse a file

Hi ArifS,

There are a number of problems with your code that would have been shown to you had you started your program off using strict and warnings. There is a function provided by File::Spec::Functions named catfile, which will put the proper separator between your directory and file. I'd also suggest using the 3 argument version of open along with a lexical variable instead of a bareword "INPUT". Example changes shown below along with use of Win32 GetFolderPath to use the Desktop as the target directory:

use strict;
use warnings;

use File::Spec::Functions;
use Win32 qw(CSIDL_DESKTOP);

my $directory = Win32::GetFolderPath(CSIDL_DESKTOP);
my $file      = "my log file.log";
my $path = catfile($directory,$file);

open my $input, '<', $path or die "Can't open INPUT: $!";
my @lines = <$input>;

print "I have access to the folder\n";
close $input;

    I tried your script replacing with the following and getting an error- 
    use Win32 qw(folder(1));

my $directory = Win32::GetFolderPath(folder(1));

    Error:
"folder(1)" is not exported by the Win32 module
Can't continue after import errors at c:\temp\dir5B6B.tmp\AccessFolder
+.pl line 8.
BEGIN failed--compilation aborted at c:\temp\dir5B6B.tmp\AccessFolder 
+line 8.

    Please let me know.

      Please explain what the following line is supposed to do:

      use Win32 qw(folder(1));

      Where did you find this syntax documented in the documentation of Win32?
