Hi

I know this isn't to do with the forums but I am a bit stuck! I'd like to pass variables from PHP to a Visual Basic programme is there anyway to do this? I thought about cookies but I don't really know.

Cookies wont do it.

Where is the PHP script, and where is the VB app?

I've done this before using TCP sockets. The PHP script was on a web server, and the VB app was on a remote personal machine. The VB app was listening to a specified port, and the PHP script simply opened IP:port, sent a string, and closed the socket. The VB app then parsed the string for needed data and performed it's functions. (this was used for RCM software)

Yep it is PHP on the web server, and the VB app on a computer.

Taht's great! How do you tell PHP to open a port and broadcast on it?

something like this:

<?
if ($flag == 1) {
$fp = fsockopen ("$IP", $Port, $errno, $errstr, 30) or die("Error ($errno): $errstr <br>\n");
fputs($fp,"$String");
fclose ($fp);
}
?>

You can read more about PHP's socket functions here (http://php.net/manual/en/function.socket.php).

I've attached a zip with a basic winsock client. It's written in Visual Basic. I haven't used it in quite a while. I made it to test my PHP script. It's listening to port 123, but you can easily change that (even in notepad).

All you'll see is a textarea. If it receives any data, it will write it to the textarea.
