Hi

I have 2 network adapters in my system and i have an array of messages
in my software component. According to the settings in the messages my
component need to send messages to either of the 2 available network
adapters.

How i can do it dynamically from user mode? or i need to write some
kernal mode switching component?

Can we dynamically bind/unbind different network adapters with TCP/IP
stack?

Can we configure network adapter from Sockets level?

Please gime some lights in this areas
Thanks in adv...

Assuming you mean plain UDP packets, not multicast, and both NICS are on
different subnets, you simply need to bind a socket to each address. If not,
then please provide more details.

Hi Phil

Thanx for your prompt ansswer..
Actually my NICs are Virtual network Drivers.. and below this virtual
driver, i am using my own different wireless or wireline transport
machanisms. So i cant differentiate it through IP addresses..

I want to switch different Network Interfaces below TCP/IP stack, can
i do it using any Windows APIs?

See e.g. the INetCfgComponentBindings interface:

But I would not actually recommend this solution for your approach.

Thanks Stephan..

Let me try with this stuff.. BTW can we use 'SetIfEntry' API for the same?
i think it will be the best solution.. right?
