in reply to How to 'invoke' a PDF file on Win32

Win32::Process is a standard module with ActiveState.
Try perldoc Win32::Process. Plenty of examples!

    I tried namely
    perldoc Win32::Process
    ! The main problem is I can not 'invoke' pdf files directly using it.

    OTOH I've almost solved this by determining of associated to '.pdf' command line and invoking that file. So, following works (with console window appearing for half of a second and then disappearing):

    use Win32::Process; sub ErrorReport{ print Win32::FormatMessage(Win32::GetLastError()); } my ($ftype) = `assoc .pdf`=~/=(.*)/; print $ftype,"\n"; my ($apath) = `ftype $ftype`=~/=(.*)/; print $apath,"\n"; my $procobj; $apath=~s/"%1"$//; $apath=~s/^"//; $apath=~s/"\s*$//; Win32::Process::Create( $procobj, "$apath", "x D:\\WORK\\Documentation\\cd-writing\\perl-technology\\root-cd-tk\ +\files\\PSAX1250_IG_R610_Iss1-mp.pdf", 0, NORMAL_PRIORITY_CLASS, "." ) || die ErrorReport();
    This works good. May be it is needed to search in registry instead of `assoc` and `ftype`. When I'll come with a final solution I'll probably report this in 'code' section.
      Here's a better solution, using the ShellExecute API. This works as-is:

      #!/usr/bin/perl -w use strict; #use diagnostics; use warnings; use Win32::API; my $ShellExecute = new Win32::API("shell32", "ShellExecute", [qw(N P P + P P N)], 'N'); my $hWnd; $ShellExecute->Call($hWnd, 'open', 'c:/rc.d.pdf', undef, undef, 1);

      Try perldoc Win32::API, then find a good API reference. A lot of VB oriented sites will have good info.

        Thank you!

        That is exactly what I've searched for... Now I will test it on different Win32 platforms and will use this.

        Warmest wishes,
