Before you start, some of you need to know that you don't belong to Ole DB, but you need a function that needs to use.
Coinitialize (); cocreateInstance (); Create a single, uninitial class object specified by CLSID. STDAPI CoCreateInstance (REECLSID rclsid, // Class identifier (CLSID) of the object LPUNKNOWN pUnkOuter, // Pointer to controlling IUnknow DWORD dwClsContext, // Context for running executable code REFIID riid, // Reference to the identifier of the interface LPVOID * ppv // Address of output variable truth receive
Refclsid Rclsid, REFIID RIID, two IDs specify components and their interfaces.
