HRESULT CoCreateInstance( REFCLSID rclsid**, LPUNKNOWN** pUnkOuter = NULL, DWORD dwClsContext = CLSCTX_ALL );
HRESULT CoCreateInstance( LPCOLESTR szProgID**, LPUNKNOWN** pUnkOuter = NULL, DWORD dwClsContext = CLSCTX_ALL );
Return value
A standard HRESULT value. Can be one of the following values:
**S_OK **An instance of the specified object class was successfully created.
**REGDB_E_CLASSNOTREG **A specified class is not registered in the registration database. Also can indicate that the type of server you requested in the CLSCTX enumeration is not registered or the values for the server types in the registry are corrupt.

dwClsContext
[in] Context in which the code that manages the newly created object will run.
szProgID
[in] ProgID associated with the data and code that will be used to create the object.
