Re: Using OLE to view given Paragraph in MS Word Document

[ricDeez]

I managed to get this to work with the changes made as per below:

#!/usr/bin/perl -w
# Simple case to open MS Word Document and view Nth paragraph
use strict;
use warnings;
use 5.012;
use Win32::OLE;
use Win32::OLE::Enum;
use Cwd qw(getcwd abs_path);

my $ParaNo = 10;            # Default target paragraph
# my $InFile = shift if @ARGV > 0;    # Required file name

#####################################################################
# For the purposes of testing, I hard-coded the file name and path  
#####################################################################

my $InFile = "C:/Users/Ric/Desktop/Report-WirelessSurvey.doc";

#####################################################################
# The following makes the code less portable, requiring $app_name to 
# be modified accordingly!
#####################################################################
# my $app_name = "Word.Application.8";        # Word's application nam
+e
# my $app;


#####################################################################
# This approach will use the active instance or will open word if
# required
#####################################################################

my $doc = Win32::OLE->GetObject ( $InFile ) or 
    die "Could not load $InFile. \n";
my $app = $doc->{Application};
$app->{Visible} = 1;

#####################################################################
# This is a good idea
#####################################################################

$app->{DisplayAlerts} = 0;

# eval {$app = Win32::OLE->GetActiveObject($app_name)};    # Use insta
+nce if already running
# die "Word ($app_name) is not installed" if $@;
# if (!defined($app))    {    
#     $app = Win32::OLE->new($app_name, sub {$_[0]->Quit;})
#         || die "Could not connect to $app_name $!";
# }
# $app->{'Visible'} = 1;

# my $abspath = abs_path($InFile);    # Word appears to need absolute 
+path
# my $doc = $app->Documents()->Open({
#     FileName => $abspath,
#     ReadOnly => 0,
#     });
# die "Can't open doc $abspath: $!" if !defined($doc);

#####################################################################
# Why are you using Win32::OLE::Enum?
#####################################################################

my $paragraphs = $doc->Paragraphs();

# my $enumerate = new Win32::OLE::Enum($paragraphs);
# if (!defined($enumerate)) {
#     die "Can't get enumerate for $InFile";
# }

my $paragraph;
# for (my $i = 0; $i<$ParaNo; $i++) {
for my $i ( 1 .. $paragraphs->Count()){
    last if $i > $ParaNo; #Forgot that you wanted to stop here!
        $paragraph = $paragraphs->Item( $i );
    ##################################################################
    # This bit needs to be in the loop!
    ##################################################################
    my $style = $paragraph->{Style}->{NameLocal};
    my $text = $paragraph->{Range}->{Text};
    print "style=$style text=$text\n";
    # print "Why doesn't the view show this location?\n";
    # print "ENTER to quit\n";
    # my $ans = <>;
    # $paragraph = $enumerate->Next();
}

Try these changes and let me know how you go. This may still trip up on unicode characters!
