Question : C / C++ DSN connect (.mdb)

Hello.

I have database with name dbcust.
Tablename - customers.
Column - ip_address.

I need to connect dsn and run query "select ip_addr from customers where ip_addr = VARIABLE";
If ip address exist then function will return true.
Else - return false.

I need C or C++ sample code (MS Visual studio 2008).
This code should work in ISAPI Filter.

Thanks.

This article shows how to use ADO

ADO Database Access with C++

If you are using MFC, its actually quite a bit easier.  Just create a CDatabase object:

...and execure this SQL statement:

  SELECT COUNT(*) FROM customers WHERE ip_addr= (put ip address here)

A non-zero return indicates that at least one match was found.
