// ADOSamp.cpp : Implementation of DLL Exports.

// You will need the NT SUR Beta 2 SDK or VC 4.2 or higher in order to build this
// project.  This is because you will need MIDL 3.00.15 or higher and new
// headers and libs.  If you have VC 4.2 or higher installed, then everything should
// already be configured correctly.

// Note: Proxy/Stub Information
//      To build a separate proxy/stub DLL,
//      run nmake -f ADOSampps.mak in the project directory.
