I don't know how to make program that will run and communicate on 2 or more computers in LAN. I tied the chat demo in delphi 4, but it didn't work. It tried to connect to my ISP by modem, but I only need to chat with other computers in LAN.

Hi.  Have a look at the TMailSlot component on my website (http://secretdelphi.cjb.net)  It's really easy to use.  If you need any help, just ask and I'll give you and example prog.

Thanks,

John.

I can email you a demo that uses TCP/IP. It's a server that can accept multiple client connections.

WHAT AM I - INVISIBLE.  Nice to see that you "Experts" value each other's ideas and opinions so much.

Mirec - I hope one day that I can answer a question for you that no-one else can, because I won't.

Thanks for acknowledging my offer.  At least to say "No thanks" would have been politer than letting me wait for 2 days to find out that you're an ignorant idiot.

Jaymol,

read Mirec's comment from "Monday, February 14 2000 - 07:05PM". He asked you to send your stuff to him, too. He said "I will try both". That includes your stuff.

Regards, Madshi.

Hi Jaymol.

I am very sorry about that thing, but to explain it I must say I am in the situation when I can connect to Internet once or twice a day for few minutes only. This question was my first and I was very glad You answered it. When I have read your comment, I tried component from Your website and NOW I know it's working. Thanx for it. I think I will use it. If it was possible I'd give You 300 points and to Epsylon 300 if he helps me.
And also I can't forget I am ignorant and I must ignore some comment from Jaymol, Tuesday, February 15, 11:26AM CET. ;-) I think there's no such a comment. Can anybody see it ?
Have a nice day Jaymol. Hope we can help each other in the future.



Hi Epsylon.

I tried your demo, but I don't know what I'm doing wrong. It don't communicate. I don't know how to fill out IP address. Can You PLEASE help me solve this problem. I have read delphi help about TClientSocket and TServerSocket components. Can there be something wrong in Windows\hosts.sam file ?
Please help me.

Thanx in advance.



Hi Madshi.




PS.: Can I split points between 2 people ?

Mirec, here's a short explanation:

1) All systems that will use this demo must have TCP/IP installed and correctly configured (use ping to find out if the computers can see each other).

2) Run the server-part on say 192.168.0.1. The server uses port 8999 to listen on.

3) Now run one or more clients on any computer in the network. You can even run multiple clients on a single computer. Each client must use 192.168.0.1 as the ip address and 8999 as the port. Just type it in the edit-boxes.

4) Once you have told the client where to find the server, click 'Connect'. Some messages will appear and if everything goes right the client is connected. Now you can type text in the left memo-box. Other clients that are connected to the same server will see the text in the right memo-box. It's just like IRC.

I hope this is enough to get it to work.

Regards,

Epsylon.

I'm not running SyGate and we are talking about a LAN here.
It should work with gateways/proxy servers. I'm not familiar with SyGate but I think it has some firewall features that prevents hackers from entering your system using a 'trojan horse'. Port 8999 my be in the range that SyGate blocks.
Just make sure it does not block port 8999 and then it should work!
