I like macros especially when they make the obtuse clear.  This is a clear case.

The e-mail below is from an external source.  Please do not open attachments or click links from an unknown or suspicious origin.

I usually love the WiX native coding style but one that bugs me is:

if (E_NOTFOUND == hr)
{
    hr = S_OK;
}

Four lines really clog up the screen especially with all the repetition for typical XML parsing (especially when throwing in S_FALSE too).

What do y'all think about something like this:

#define NotFoundIsOK(hr) if (E_NOTFOUND == hr) { hr = S_OK; }

hr = XmlGetAttributeEx(pixn, L"Name", &pFoo->sczName); NotFoundIsOK(hr); ExitOnFailure(hr, "Failed when querying foo Name.");
