Detecting the use of HRESULTs as bools

We have a big 开发者_StackOverflow社区body of code that was refactored so that stuff which was plain-old C++ is now COM.

I've been spending the last couple of days hunting out places in which we missed the fact that a function that previously returned a bool now returns an HRESULT (the problem is compound by the fact that S_OK == false).

Is there a way to detect places in which an HRESULT is being used as a bool (and vice versa)?

We're using Visual Studio 2005 (VS8) Professional.

Is there anything other than @Steve's excellent suggestion which doesn't involve installing Team Edition?

Are you using Code Analysis for C++?

If so, you should see

or

Also verify your source code (via #pragma) and project options do not disable these or other important warnings.
