DllGetClassObject
The DllGetClassObject function is the entry point used by C+ + file and stream handlers to create
an instance of the handler.
STDAPI DllGetClassObject(
const CLSID & rclsid,
|
| const IID & riid,
|
| void ** ppv)
|
|
Parameters
rclsid
Class identifier of the file or stream handler.
riid
Interface identifier of the file or stream handler.
ppv
Address returned for the object of the interface query. If the interface
specified in riid is not supported by the object, S_FALSE is returned and the ppvObj parameter used in the IUnknown interface must be set to NULL.
Return Values
Returns a handle of an instance of the file or stream handler.
Remarks
DllGetClassObject is the only export function your DLL needs. The OLE component object DLL
calls this function to obtain an instance of the stream- or file-handler interface.
Your file or stream handler should ensure that the system requests the correct
class identifier before creating an instance of it.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
