Is LAN required to run winsock control....( Please folks help me out )

[arunb]

Hi,

I am using winsock control to exchange data between two VB applications , both running on the SAME PC. The protocol used is UDP, with IP address as 127.0.0.1 etc.

The programs are working well and I am able to exchange data .

My question is do I really need a LAN card to exchange data between two applications running on the SAME PC.

This question is very important for my applications , otherwise I will have to use DDE or some such method for data exchange.


thanks

Note : My computer has a LAN card attached to it.

no, you do not have to have a lan card to use winsock

Hi,

OS: Windows 98/Windows XP
Dev. : Microsoft Visual Basic 6.0

Thank you very much for the reply. I tested a simple client-server applications in VB on a computer (running on Windows 98) that did not have a modem or a LAN card and I got the error

Runtime Error 10047: Address Family not supported
The appplication just terminated after this message...


kindly advise what is wrong...

Install a Generic Modem on your serial port, even if you don't have one.
This will load TCP/IP and the bindings necessary for your app to run.

btw - don't use the com port that the mouse may be using.

Hi,

I could do that but I need the spare serial port as well. Is there any way in which the Generic modem may be installed in the PCI bus ??

thanks

Nope, then it'd have to talk to the hardware.
