You may have a Window's related problem, where Tk's fileevent dosn't work reliably on some version of windows. See Client/Server sockets with TK on Win32 .

There are workarounds, see Another Win32 Tk fileevent work around : using ioctl() properly for instance. If that dosn't work for you, it's possible to use a conventional select loop with sysread in a separate subroutine, and call it with a Tk timer every 10 milliseconds. See Tk fileevent with win32 sockets for a timer solution.

It goes something like this untested code:

... other Tk code 
my $timer = $mw->repeat(10, \&read_it );
MainLoop;

sub read_it{
   my $client = $listen->accept or die "Accept failed: $!";
   if( IO::Select->new($client)->can_read(5) ) {
      sysread( $client, $_, 1 ) and print;
   } else {   print "Timeout\n";
   } close $client;
}

If you are an eager seeker of Perl knowledge, I will tell you that another, more advanced GUI toolkit, called Gtk2 does have an IO watch ( like fileevent ) which does work on Windows, see Simple threaded chat server for a simple example to test with.

Finally, you could just put Ubuntu Linux on your Desktop with a dual boot to Windows. :-)

Finally, just to get you banging your head against the wall, I found an example of Wx using sockets, see Wx Socket. It probably works on Windows.

LOL!!! Finally, just to get you banging your head against the wall, I found an example of Wx using sockets,

Thanks for all the info. I will play with it when I get home from work.

Well it's been a long week of trial and error.

Had things happen with Tk, had things happen with Wx.

I'm back to the start. Wx.

The window opens after the server gets a connection. The Window has to open and display the IP First.

Then display the text from the client. And display the next set of text from the client.

And send the commands to the computer. I'm still stuck with "What to do instead of While"

                exit;           # Terminate

Run the server first. Type anything into the client. Commands are if you have X10 installed "A1 On"

Have you seen Gtk2 server and client GUI's with root messaging? :-) It should work on Windows. Wx generally uses Gtk libs as a basis, so if you have Wx installed you can probably install Gtk2. See Installing Gtk2 using PPM on Windows and Install GTK2 for example.

But back to Wx:

I don't have Wx running, but looking at your server code, I see you did not get the previous point I was making about GUI eventloop code, and using sleep, system, while loops, select loops, or anything which interferes with the eventloop. Your code , as written, will just hang in the while loop, making the Wx eventloop freeze up. I don't even have to run it to see that.

You must use Wx::Socket to run sockets in Wx. Otherwise, you need to put all your while loops into a separate thread, and at your level of programming experience, I doubt you are up to that hassle. Go back and rewrite your code using the example code in Wx::Socket

Can't locate Tk.pm in @INC (@INC contains: C:/Dwimperl/perl/site/lib C:/Dwimperl /perl/vendor/lib C:/Dwimperl/perl/lib .) at monkserver.pl line 5.

Seems like it should be easy to fix, but I don't know what a @INC is.
