network between XP and Windows 7

| Has anybody tried it? I used to have my game working a long time ago with two XP computers. Now can not get it to work with windows 7 and XP. But I am able to share files, and printer etc. from windows, no problem. I used IPconfig to get my computers IP address. Any suggestions? |

| Could be windows firewall blocking either incoming or outgoing connections on the port that you're using... (Or possibly a 3rd party program like zonealarm, or even antivirus program if you're using a suspicious port like 25) |

| I got it to work with a XP laptop, still can't get it to work with Windows 7 I tried disabling firewall and antivirus program Do I need to mess with network adpater properties more specifically Intel 8256v-2 Gigabit network connection properties |

| Do I need to mess with network adpater properties more specifically Very unlikely. There are differences between XP and Windows 7 though. It's also possible that the communication *port* that you're using may already be in use by another program. - What port are you using? - You can use Sysinternal's TCPView to see if there is already a program trying to use the same port as your app is |

| I don't know how blitzplus selects port number.... I ran TCPView, (first time I've used it) On the XP computer I can see that the program uses Ports 2300,2350,44999,57218 On the Windows 7 computer it seems to want to use 2300,2350,4894,9539 I'm no expert when it comes to ports or networks, so not sure what to look for. I don't know how I can tell if there is a port conflict. I'm able to ping the computers... XP to windows 7 and Windows 7 to XP no problem. |

| Assuming you are using the built-in networking commands, you specify the port you're listening on. On the 'server': CreateTCPServer(port) On the 'client': OpenTCPStream (ip$,port) The 'port' parameter is the port used to listen on, and to send to. (There's also a randomly assigned port for the outgoing traffic, but that port number is pretty much irrelevant as long as you aren't actively blocking the outgoing connection in a software firewall... So... - What port value are you specifying in your program? - Check in TCP view to make sure that there is no other program listening on that specific port. For example, I've ran into problems there myself in the past because I was trying to run a webserver on port 80, but couldn't because Skype was already listening on that port for a fall-back connection. Many common ports may already be in use by another application. Look at the contents of the file c:\windows\system32\drivers\etc\services to find a list of common ports that you should avoid to decrease the likelyhood of interfering with other programs and services... |

| Looks like I've been using DirectPlay. I was not even aware of TCP(network). I originally wrote it in Blitzbasic not Blitzplus. Do you recommend I rewrite it using TCP(network). Is there any examples of how to exchange variable data (integers and floating point) between the two computers. Thanks Dan |

| I do recommend you to rewrite it using TCP commands. Usually to set up a TCP connection you do something like 'server': svr=CreateTCPServer(port) Repeat stream=AccepTCPStream(svr) Until stream 'client': stream=OpenTCPStream(ip,port) Then you have a stream object (actually a pointer to the stream buffer) in which you can write your data (and read it) using ReadByte, WriteString etc |
