I believe the following is the kind of thing you're after:
package Typelibs; use warnings; use strict; use Win32::OLE::Const; # list of all registered type libraries my @Library; Win32::OLE::Const->EnumTypeLibs(sub { my ($clsid,$title,$version,$langid,$filename) = @_; return unless $version =~ /^([0-9a-fA-F]+)\.([0-9a-fA-F]+)$/; my ($maj,$min) = (hex($1), hex($2)); push @Library, [$clsid,$title,$maj,$min,$langid,$filename]; }); sub ExistsTypeLib { my $typelib = shift; for my $lib (@Library) { return @$lib if($lib->[1] =~ /^$typelib/); } return undef; } 1;

You can then call TypeLibs::ExistsTypeLib('Microsoft Excel') and it should return a list consisting of the ClassID, Title, Major Version Number, Minor Version Number, LanguageID, and Executable Filename.

I now have a modified version to check whether Outlook is installed for my Outlook CPAN modules.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
