in reply to Starting a process under Win32

The problem is that the documentation is not clear, partly because of the way Microsoft document the underlying API CreateProcess. The 3rd argument must be the complete command-line, including the program name:
my $program = 'C:\\Program Files\\VideoLAN\\VLC\\vlc.exe',

Win32::Process::Create( $p,
                        $program,
                        "$program --rc-host 127.0.0.1:9999",
                        0,
                        NORMAL_PRIORITY_CLASS,
                        '.' ) or die;

Note that the full path-name must be included.

    Seems clear to me 
    SYNOPSIS
        use Win32::Process;
        use Win32;

        sub ErrorReport{
            print Win32::FormatMessage( Win32::GetLastError() );
        }

        Win32::Process::Create($ProcessObj,
                                   "C:\\winnt\\system32\\notepad.exe",
                                    "notepad temp.txt",
                                    0,
                                    NORMAL_PRIORITY_CLASS,
                                    ".")|| die ErrorReport();

        $ProcessObj->Suspend();
        $ProcessObj->Resume();
        $ProcessObj->Wait(INFINITE);

    The program name needs to have the full path in the 2nd argument, but not the 3rd.

    I've changed it to 
    Win32::Process::Create( $p,
                        "C:\\Program Files\\VideoLAN\\VLC\\vlc.exe",
                        "C:\\Program Files\\VideoLAN\\VLC\\vlc.exe --r
+c-host 127.0.0.1:9999",
                        0,
                        NORMAL_PRIORITY_CLASS,
                        '.' ) or die $! . $^E;

    Still the same problem, VLC reports the command line is no good.

      OK. What is the exact text of the error message?
[reply]
        The command line options couldn't be loaded, check that they are valid
+.

Press the RETURN key to continue...

        This error is coming from VLC, the perl script reports no error at the Create() call.
