    Those are memory leaks that VC6 debugger finds in templatesign.cpp:

    Are they real?

No, it's handled by the signature

 

From the docs.

DSIGSignature::createReference

Creates a new DSIGReference, adds it to the list of references handled by the owning DSIGSignature

Berin,

        Should I delete DSIGReference (and when?) returned from DSIGSignature::CreateReference() function? I have this peace of code:

} else {
        DSIGReference *ref;
        ref = sig->createReference(MAKE_UNICODE_STRING(""));

        DSIGTransformEnvelope *env = ref->appendEnvelopedSignatureTransform();
        DSIGTransformC14n     *c14 = ref->appendCanonicalizationTransform(CANON_C14NE_NOC);
}

I'm reading memory leaks here:

I've tried to delete "ref" variable but failed.

Best regards,
Milan
