I do not understand why you want to directly use a tcp/ip connection for fetching the data.

Rather creater a dsn to be used over the network to access the sqlserver data.

From your Cpp file use Sqlconnect using the dsn name. Prepare the stmt and exceute the sql statement to retrieve the data.

I'm using tcp/ip to transfer those data from my sql server 2000 to my client.

You suggest that to use:

Q1) How do i do that?
Q2) Can you provide some source codes?

Thank You
