I want to use C program to connect MS SQL server.
I copied some sample file to install on my computer.
When I run the program, an error occurred, which is about ntwdblib.dll
not find in some paths.
But when I check the paths again, they have ntwdblib.dll.
When I run my C program in another computer, it works...
so , I feel very frustrated.
In my C program, I include the following libraries.
#defineDBNTWIN32
#include "windows.h"
#include <sqlfront.h>
#include <sqldb.h>
#include <stdio.h
Also, I don't know the meaning of "#defineDBNTWIN32".
I haven't installed SQL Client on my computer. Is it the main
problem??
Pls help!!
Cheers,

Yes, that is the problem. NTWDBLIB.DLL is the DLL for DB-Library, which
is not part of MDAC, so SQL connectivity is about the only way to install
it.
DB-Library is a very good client library, but unfortunately Microsoft
does not agree, so they stopped developmet of DB-Lib many years ago.
As a consequence, you have restricted support for new features in
SQL Server with DB-Library.
Unless you have some legacy software you are working with, I'd recommend
you to use ODBC or OLE DB instead.
