in reply to Win32 wperl open Console when system

Using cmd.exe to launch the default program will always open a console window (if none is open already), because cmd.exe is a console program:

qx{start "$pdf" /b };

If you want to avoid that, don't involve the start command of cmd.exe and instead do what the command does, by using the AssocQueryStringA function, as in this Stackoverflow post. Doing so shouldn't be too hard using Win32::API, but I can't test it right now.

    unfortunatly, .pdf has no default association in HKEY_CLASS_ROOT for .pdf :-(

    And if I directly run "C:\Program Files\Internet Explorer\iexplore.exe" file.pdf, it asks what to do with the file instead of displaying it directly...

      You first said "explorer" (files) now you say iexplore (internet)?

      These are two different programs.

      this C:\>C:\Windows\explorer.exe \tmp\xxx.pdf works for me from the console (cmd.exe)


      this doesn't :/

      perl -e"`C:/Windows/explorer.exe /tmp/xxx.pdf`"

      Wikisyntax for the Monastery FootballPerl is like chess, only without the dice

        perl -e "qx(explorer.exe C:\Path\To\my.pdf)"
        opens the explorer, but
        perl -e "qx'explorer.exe C:\Path\To\my.pdf'"
        opens my pdf

        only difference is the qx delimiter. (insert smiley with gaping open mouth here)
