user defined data type in com dll

Hello

I am writing a com dll, i am trying to use a structure variable
in on of the interface but it gives me error on compilation. I just wanted
to know whether i can use user defined data types in interface of com dll.


[id(5), helpstring("method GetData")] HRESULT GetData([in] WAYPOINTS &wp);

I get the following error

expecting a type specification near "WAYPOINTS"

You can, but the structure has to be defined in the same IDL or in an
imported IDL file. It looks like you are using a structure without
defining it first.
