in thread Changing process name

I use wxPerl (wxWidgets) to start subprocesses, so I can't use exec or system.

Then how do you "start subprocesses"?

The probablility is that under Win32, you could system 1, 'perl.exe script.pl'; as this does an asynchronous spawn. Ie. It returns immediately and so does not upset GUI message loops.

Similarly, you could probably use system 'perl script &'; under Linux to achieve the same end.

    Looks like this: 
    my $szPerlExe = $this->{$this->{choPerlExecutable}->GetStringSelection
+()};
my $szShell = $this->{stcShell}->GetText();
$szShell =~ s/"/\\"/g;
my $szCommand = $szPerlExe.' -e '.'"'.$szShell.'"';

$this->{wProcessId} = Wx::NewId();
$this->{hProcess} = Wx::Process->new($this, $this->{wProcessId});
$this->{hProcess}->Redirect();
$this->{hProcess}->CloseOutput();

my $wProcessPid = Wx::ExecuteCommand($szCommand, wxEXEC_ASYNC|wxEXEC_N
+OHIDE, $this->{hProcess});
$this->{wProcessPID}->{$wProcessPid} = $szTimeStamp;

$this->{tmrProcessRunning} = Wx::Timer->new($this, $this->{wProcessId}
+);
$this->{tmrProcessRunning}->Start(500);

EVT_TIMER($this, $this->{wProcessId}, \&ProcessRunning_OnTimer);

EVT_END_PROCESS($this, $this->{wProcessId}, \&ProcessEnded);

    So I need a way to change the name of a process from within the executed script. I also use this kind of execution for system commands and scripts (without perl -e)

      Well. There is no way of doing this on Win32 that I am aware of, and I've looked pretty hard. As noted elsewhere, this is "by design", as executables that can change their apparent name is a security hole.

      WxPerl is outside of my experience and sufficiently different from similar stuff (Tk) that I doubt I can help.

      One thought that does cross my mind is: How are the commands run? Does a new (console) window appear or are they run strictly in the background?

      If they run in a window, would changing the title of the window be sufficient to differentiate them?

        If I executed my App with perl and there is a console window 
opened for it not. Maybe if I use wperl (which do not open a 
console), then the executed script opens a new console window,
but I'm not sure. 

So it looks like I have to differentiate them by Process Id 
and the timestamp, when they where executed. It isnt that kind of problem anyway, it would just be better if.

Thanks anyway
