Hi, LJ> Hello... the following script seems to work.
LJ> Factors to consider: LJ> 1)The stack should be set to purge itself from memory upon closing LJ> 2)Some firewalls might prevent the program from accepting LJ> connections on a port LJ> 3)This prevents multiple instances, but still does not quite allow LJ> the two instances to communicate. Writing to a socket from one instance LJ> seems to steal the ability of the other instance to listen to that LJ> socket - I am still trying to work out how to do that. humm, with my little experience, you probably need to differenciate the 1st instance from the second. if the first do a accept connection ( Server mode ) the second instance should do a connect as a client. So, if you see yourself in the netstat result then run a open socket on the port. LJ> 4)You might want to consider hiding the windows console and LJ> setting the cursor to watch while the script performs the shell command. LJ> 5)This will not work with the opensockets function, because that LJ> does not return the sockets opened by the other instance. The shell LJ> command for this works quite well (at least on my computer). LJ> Cheers, LJ> Jonathan LJ> on preopenstack LJ> get shell("netstat -a") LJ> put it into OPS LJ> put the number of lines in OPS into Z LJ> set the itemdelimiter to ":" LJ> repeat with X = 1 to Z LJ> put word 2 of line X of OPS into WPS LJ> if item 2 of WPS = "48953" then put "open" into queryold LJ> end repeat LJ> if queryold = "open" then LJ> answer "This program is already running, do you wish to run another LJ> instance of it?" with "No" and "Yes" LJ> put it into AAA LJ> if AAA = "No" then LJ> close this stack LJ> end if LJ> else LJ> accept connections on port 48953 with message "queryinstance" LJ> end if LJ> end preopenstack Running get shell("netstat -a") , i got this on a Win98 box : Active Connections Proto Local Address Foreign Address State TCP xxxxx:1068 0.0.0.0:0 LISTENING TCP xxxxx:2530 0.0.0.0:0 LISTENING TCP xxxxx:1068 127.0.0.1:2530 ESTABLISHED TCP xxxxx:2530 127.0.0.1:1068 ESTABLISHED what i don't understand is that i do only one <accept connection>, and then only one external process read the socket. So, why this 4 lines ? Regards, thierry _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
