Hi Every body I want to know how it is possible to connect to database whether it may be Oracle,Ms-Access.I am using Turboc2 Compiler and windows OS and i found something like ProC that is file extension as .pc in Oracle 9i is there any relation between these i want to have a simple example on this topic.

use ODBC calls to connect to databases. See google for lots of examples and a few c++ classes. But you cannot do that at all with Turbo C because that compiler is too old, you will have to upgrade to a new compiler like Borland Builder, Dev-C++, or Microsoft VC++ 2005.
