Remarks
If the requested object is in a DLL (in-process server), you will always use the NewCom option, as you're asking for a new object. If the request is successful, the object reference is assigned to the iDispatchVariable.
If the requested object is in an EXE (out-of-process server), you may use any of the three options: NewCom, GetCom, AnyCom.
•with NewCom: a new instance of a COM application is created.
with GetCom: an interface will be opened on an existing, running application, which has been registered as the active automation object for its class.
•with AnyCom: first try to use an existing, running application if available, or a new instance if not.
