ComponentOccurrence of a missing (skipped?) component?

[oransen]

If I loop over the component occurrences in an assembly, but some of these occurrences are missing and have been skipped by the user, what does...

        CComPtr<ComponentOccurrence> pCompOcc;
        hRes = pOccs->get_Item(lOccCount, &pCompOcc);
        // pCompOcc appears to be unavailable, but hRes has returned OK

...give me? If I check pCompOcc == nullptr I get an exception. Is there some member of ComponentOccurrence which tells me it is skipped?

I think what you are looking for is this:

Occurrence.ReferencedDocumentDescriptor.ReferenceMissing

This will return true if the component is unresolved or if the occurrence is suppressed. So a better option could be:

Not Occurrence.Suppressed AndAlso Occurrence.ReferencedDocumentDescriptor.ReferenceMissing

Thanks for that, I'll try it in C++ COM and let you know.

@j.haggenjos, many thanks for that it works, and here it is in C++ COM:

CComPtr<ComponentOccurrence> pCompOcc;
hRes = pOccs->get_Item(lOccCount, &pCompOcc);
if (FAILED(hRes)) {
    gLogger.Printf(ekErrMsg, L"Could not get a component");
    return false;
}

if (VARIANT_TRUE == pCompOcc->ReferencedDocumentDescriptor->ReferenceMissing) {
    // Maybe a missing and skipped component...
    continue ;
}
