* NOTES
|
|
* The dwClsContext parameter can be one or more of the following:
|
|
*| CLSCTX_INPROC_SERVER - Use an in-process server, such as from a DLL.
|
|
*| CLSCTX_INPROC_HANDLER - Use an in-process object which handles certain functions for an object running in another process.

|
*| CLSCTX_LOCAL_SERVER - Connect to an object running in another process.
|
|
*| CLSCTX_REMOTE_SERVER - Connect to an object running on another machine.
|
|
*
|
|
* Aggregation is the concept of deferring the IUnknown of an object to another
|
|
* object. This allows a separate object to behave as though it was part of
|
|
* the object and to allow this the pUnkOuter parameter can be set. Note that
|
|
