You're duplicating the code that handles VT_I4 case. Please avoid it.

Do you think, this code will be better? And can I truncate "VT_I4" from trace?

if(V_VT(&name) == VT_I4 || V_VT(&name) == VT_INT) {
        int i;

if (V_VT(&name) == VT_I4) {
            i = V_I4(&name);
            TRACE("name is VT_I4: %d\n", i);
        }
        else {
            i = V_INT(&name);
            TRACE("name is VT_INT: %d\n", i);
        }

if(i < 0)
            return E_INVALIDARG;
        if(i >= This->len)
            return S_OK;

*pdisp = (IDispatch*)This->elems[i];
        IDispatch_AddRef(*pdisp);
        TRACE("Returning pdisp=%p\n", pdisp);
        return S_OK;
    }

And about my test for this problem - it's OK?

Yes, it looks better, but I'd suggest to move this code to separated 
function.

Yes, it's OK. There is one improvement that would be nice to have. You 
could test returned disp better than comparing to NULL. It could look 
like an attached patch (compile tested only).
Also tests must pass after each patch, so you should change order of 
patches or mark them as todo_wine and remove todo_wine in second patch 
or send both changes in one patch. I'd suggest sending in one patch in 
this case.

Thanks,
