java - In which DLL is the COM interface iStream defined? -

i'm complete newbie windows , com programming, trying use com4j in order call com object java.

com4j generates java interfaces com definitions "often found in .ocx, .dll, .exe, and/or .tlb files" . easy me locate .ocx file of target com object, have no clue regarding standard interface istream.

microsoft's documentation mentions ole32.dll ( c:\windows\windows32\ole32.dll ?) , neither com4j generator nor oleviewer succeed in opening file.

any hints?

it looks defined in comsvcs.dll .
