    IDL Problem

    Consider this:

    VB Code:
    1. [

    2.     uuid(27dbef8a-e493-40b9-8ac5-92d064cba696),

    3.     version(1.0)

    4. ]

    5.  
    6. library Test

    7. {

    8.  
    9.     importlib("stdole2.tlb");

    10.  
    11.     struct Test {

    12.         long Bob;

    13.     };

    14.  
    15.  
    16.     [

    17.         uuid(127ee650-1258-11db-9cd8-0800200c9a66),

    18.         object,

    19.         oleautomation

    20.     ]

    21.     interface ITest : IUnknown

    22.     {

    23.         HRESULT Test ([out,retval] SAFEARRAY(struct Test)*);

    24.     };

    25.  
    26. }

    It compiles with : warning MIDL 2039 : interface does not conform to [oleautomation] attribute : [Parameter of Procedure 'Test' ( interface 'ITest')]

    The VB6 IDE concurs with this and I am unable to set a reference to the created TLB.

    The problem is in specifying the return of an array of UDT's in the function specification. I can drop OleAutomation and things will work, but I can't then use the Universal Marshaller which is what i need to do (remote COM+ application)

    Using the obsolete mktylib, and the MIDL mktyplib203 switch makes no difference, either. I am using MIDL v5.01.0164

    If anyone has *any* clue why this doesn't work I would be eternally grateful.

    Can anyone else actually replication the problem?

    It's turtles! And it's all the way down
